Description

  The present invention relates to the field of communication technology, and more particularly to a method and terminal for establishing a communication connection.

  Near field communication (NFC for short) is a short-range wireless communication technology. It is based on radio frequency identification (RFID for short) technology and realizes short-range communication between electronic devices using electromagnetic induction. The user need only touch or approach the device to achieve visual, secure and contactless information exchange, payment transactions, and the like. NFC works on a 13.56 MHz frequency and supports four rates: 106 kbit / s, 212 kbit / s, 424 kbit / s and 848 kbit / s. NFC can function within a range of 20 centimeters, with a typical value of 4 cm. NFC is well suited for exchanging small data due to its simple operation and low data transmission rate, and for large files (eg high definition pictures or high definition videos with megabyte scores, etc.) When used, the slow disadvantage has a significant impact on the user experience. Therefore, the NFC Forum has proposed an NFC-based connection handover technology. Two terminals that simultaneously support NFC, Bluetooth, and Wi-Fi (Wireless Fidelity, abbreviated to Wi-Fi for short) use NFC to exchange Bluetooth or Wi-Fi connection configuration information. You may make it do. Thereafter, the terminal may establish a Bluetooth connection or a Wi-Fi connection using the configuration information, and transmit a large file using the established Bluetooth connection or the Wi-Fi connection.

  The step 102 established between the first terminal and the second terminal according to the Wi-Fi Direct configuration information with which the Wi-Fi Direct connection has been exchanged is as follows: If it is determined that neither the first terminal nor the second terminal is a member of the existing group according to the group information, the first terminal uses the Wi-Fi Direct configuration information of the first terminal and the Wi-Fi of the second terminal. Establish Wi-Fi Direct connection with the second terminal according to the Fi Direct configuration information, or the first terminal and the second terminal according to the group information of the first terminal and the group information of the second terminal If the first terminal determines that at least one of the members is a member of an existing group, the first terminal Or establishing a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the new group to be created.

  In this embodiment, the first terminal establishes a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the new group scheduled to be created by the first terminal. It should be noted that it means creating.

In the present embodiment, the Wi-Fi Direct configuration information of the first terminal includes group information of the first terminal, where the value of the group information of the first terminal is a member of an existing group of the first terminal. The first terminal may be a group owner of an existing group to which the first terminal belongs, or the first terminal may be a client of an existing group to which the first terminal belongs. The Wi-Fi Direct configuration information of the terminal may further include the group owner intention of the first terminal, the number of MAC entities in the first terminal, and the address of each MAC entity,
The Wi-Fi Direct configuration information of the second terminal further includes the group owner intention of the second terminal, the number of MAC entities in the second terminal, and the address of each MAC entity, where the group information of the second terminal The value is that the second terminal is not a member of an existing group, that the second terminal is a group owner of an existing group to which the second terminal belongs, or that the second terminal is a client of an existing group to which the second terminal belongs. It may be,

  In one implementation of this embodiment, when the first terminal determines that neither the first terminal nor the second terminal is a member of an existing group according to the group information of the first terminal and the group information of the second terminal The first terminal establishes a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the first terminal and the Wi-Fi Direct configuration information of the second terminal. The Wi-Fi Direct configuration information of a new group to be created is set according to the Wi-Fi Direct configuration information of the first terminal and the Wi-Fi Direct configuration information of the second terminal, and then the first terminal is NFC Wi of the new group scheduled to be created on the second terminal via the connection Fi Direct configuration information may be transmitted, and finally, the first terminal may establish a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the new group to be created. .

  For example, when setting Wi-Fi Direct configuration information of a new group scheduled to be created, such as when setting an identifier of a new group scheduled to be created, the first terminal uses the Wi-Fi Direct configuration of the first terminal. Use the group identifier in the information, use the group identifier in the Wi-Fi Direct configuration information of the second terminal, do not use the group identifier in the Wi-Fi Direct configuration information of the first terminal, or A new identifier may be set for a new group to be created without using the group identifier in the Wi-Fi Direct configuration information of the second terminal. Similarly, the BSSID of the new group to be created, the operating channel of the new group to be created, the IP base address of the new group to be created, and the MAC entity address used in the new group to be created are also described above. That is, the corresponding information included in the Wi-Fi Direct configuration information of the first terminal or the second terminal may be used, or a new value is set. Details are not repeated here.

In another implementation method of this embodiment, the first terminal determines that at least one of the first terminal and the second terminal is a member of an existing group according to the group information of the first terminal and the group information of the second terminal. To do

  Furthermore, the first terminal receives the default setting of the second terminal transmitted by the second terminal via the NFC connection. Specifically, the default setting of the second terminal may be included in the Wi-Fi Direct configuration information of the second terminal and transmitted to the first terminal, or the default setting may also be The Wi-Fi Direct configuration information may not be included in the Wi-Fi Direct configuration information and is transmitted to the first terminal together with the Wi-Fi Direct configuration information of the second terminal. Here, the default setting is that the second terminal belongs to the first terminal. Reflects that it is requesting to join an existing group or that the second terminal is requesting to create a new group with the first terminal.

  In a specific implementation of this implementation, the first terminal establishes a Wi-Fi Direct connection with the second terminal in accordance with the existing group's Wi-Fi Direct configuration information. It is determined that the second terminal is requesting to join the existing group to which the first terminal belongs according to the default setting, and the first terminal is the existing to which the first terminal belongs according to the group information of the first terminal. If the second terminal determines that it is the group owner of the group, the second terminal sets the value of the group owner intent in the Wi-Fi Direct configuration information of the second terminal according to the Wi-Fi Direct configuration information of the existing group. -Group owner in Fi Direct configuration information The first terminal transmits Wi-Fi Direct configuration information of the existing group to which the first terminal belongs to the second terminal via the NFC connection so as to set a value smaller than the intended value, and thus, Since the second terminal joins the existing group to which the first terminal belongs, the second terminal can be used as a client. Thereafter, the first terminal can perform Wi-Fi with the second terminal according to the Wi-Fi Direct configuration information of the existing group. It may be to establish a Direct connection.

  In another specific implementation scheme of the present implementation scheme, the first terminal establishes a Wi-Fi Direct connection with the second terminal according to the existing group's Wi-Fi Direct configuration information. According to the default setting of the terminal, it is determined that the second terminal requests to join the existing group to which the first terminal belongs, and the first terminal belongs to the first terminal according to the group information of the first terminal If it is determined that the client is an existing group client, the second terminal requests encryption information in the existing group's Wi-Fi Direct configuration information from the group owner according to the description information of the group owner, and is transmitted by the group owner. In the Wi-Fi Direct configuration information of the existing group The first terminal excludes the encryption information in the Wi-Fi Direct configuration information of the existing group and the description information of the group owner of the existing group via the NFC connection so as to receive the encryption information Configuration information is transmitted, and in this way, the second terminal acquires all Wi-Fi Direct configuration information of the existing group to which the first terminal belongs, and then the first terminal It may be to establish a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information.

  In yet another specific implementation of this implementation, establishing a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the new group that the first terminal is scheduled to create is When one terminal determines that the second terminal requests to create a new group with the first terminal according to the default setting of the second terminal, and the first terminal has at least one unused MAC entity If the first terminal determines, the first terminal selects one of the unused MAC entities in the first terminal as the MAC entity to be used by the first terminal in the new group to be created and Group Wi-Fi Direct configuration information is set, and then the first terminal is connected via an NFC connection. The Wi-Fi Direct configuration information of the new group scheduled to be created is transmitted to the second terminal, and the Wi-Fi Direct connection with the second terminal is established according to the Wi-Fi Direct configuration information of the new group scheduled to be created. Here, the Wi-Fi Direct configuration information of the new group scheduled to be created is consistent with the Wi-Fi Direct configuration information of the existing group to which the first terminal belongs, and The group Wi-Fi Direct configuration information further includes group information of the first terminal. Specifically, when setting Wi-Fi Direct configuration information of a new group to be created, the first terminal may use part or all of the Wi-Fi Direct configuration information of the second terminal. Alternatively, the new Wi-Fi Direct configuration information of a new group to be created may be set without using the Wi-Fi Direct configuration information of the second terminal.

  In yet another specific implementation of this implementation, establishing a Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the new group that the first terminal is scheduled to create is One terminal determines that the second terminal requests to create a new group with the first terminal according to the default setting of the second terminal, and the first terminal uses all the MAC entities in the first terminal. The first terminal prompts the user using the first terminal to quit the existing group to which the first terminal belongs, and the user using the first terminal selects the existing group to which the first terminal belongs. If the user chooses to quit, the first terminal quits the existing group to which the first terminal belongs, and then the Wi-Fi Direct configuration of the first terminal. The Wi-Fi Direct configuration information of the new group to be created may be set according to the location information and the Wi-Fi Direct configuration information of the second terminal. Here, the group owner of the first terminal may be set. The intention value is different from the group owner intention value of the second terminal in the Wi-Fi Direct configuration information of the new group to be created. Next, the first terminal is scheduled to create the second terminal via the NFC connection. The Wi-Fi Direct configuration information of the new group may be transmitted, and the Wi-Fi Direct connection with the second terminal may be established according to the Wi-Fi Direct configuration information of the new group to be created.

  In yet another implementation method of the present embodiment, at least one of the first terminal and the second terminal is a member of an existing group according to the group information of the first terminal and the group information of the second terminal.

Configuration information excluding encryption information in the Wi-Fi Direct configuration information of the group, and further, the first terminal is transmitted by the second terminal via the NFC connection, and the group owner of the existing group to which the second terminal belongs The description information is received. Specifically, the description information of the group owner of the existing group to which the second terminal belongs may be included in the Wi-Fi Direct configuration information of the second terminal, or the existing group to which the second terminal belongs. The group owner description information may not be included in the Wi-Fi Direct configuration information of the second terminal, and is transmitted to the first terminal together with the Wi-Fi Direct configuration information of the second terminal.

  In this way, the first terminal establishes the Wi-Fi Direct connection with the second terminal according to the Wi-Fi Direct configuration information of the existing group. The first terminal follows the default setting of the first terminal, It is determined that the first terminal is requesting to join the existing group to which the second terminal belongs, and the first terminal belongs according to the description information of the group owner of the existing group to which the second terminal belongs Request encryption information in the Wi-Fi Direct configuration information of the existing group from the group owner, receive the encryption information in the Wi-Fi Direct configuration information of the existing group transmitted by the group owner, and then One terminal is a Wi-Fi Direct link for an existing group.

In this embodiment, the Wi-Fi Direct configuration information of the terminal B further includes the group owner intention of the terminal B, the number of MAC entities in the terminal B, and the address of each MAC entity. Here, the group information of the terminal B The value of is that terminal B is not a member of an existing group, that terminal B is a group owner of an existing group to which terminal B belongs, or that terminal B is a client of an existing group to which terminal B belongs. You can,
The Wi-Fi Direct configuration information of the terminal A further includes the group owner intention of the terminal A, the number of MAC entities in the terminal A, and the address of each MAC entity, where the value of the group information of the terminal A is the terminal It may be that A is not a member of an existing group, terminal A is a group owner of an existing group to which terminal A belongs, or terminal A is a client of an existing group to which terminal A belongs.

  Step 603: Terminal B determines that one of terminal B and terminal A is a member of an existing group according to the group information of terminal A and terminal B. If terminal B is a member of an existing group and terminal A is not a member of an existing group, step 604 is executed and terminal B is not a member of an existing group and terminal A is a member of an existing group Step 620 is executed.

  Step 604: Terminal B receives the default setting of terminal A transmitted by terminal A via an NFC connection.

  Specifically, the default setting of terminal A may be included in the Wi-Fi Direct configuration information of terminal A, or the default setting may not be included in the Wi-Fi Direct configuration information of terminal A. However, it is transmitted to the terminal B together with the Wi-Fi Direct configuration information of the terminal A.

  The default settings for terminal A reflect that terminal A is requesting to join an existing group to which terminal B belongs or that terminal A is requesting to create a new group with terminal B. .

  Step 605: Terminal B determines whether terminal A requests to join the existing group to which terminal B belongs according to the default setting of terminal A, and requests that terminal A join to the existing group to which terminal B belongs If so, step 606 is executed or if terminal A is not requesting to join the existing group to which terminal B belongs, i.e. terminal B is in terminal B according to the default settings of terminal A. If a new group is requested to be created, step 613 is executed.

  Step 606: According to the group information of terminal B, terminal B determines whether terminal B is a group owner of an existing group to which terminal B belongs. If terminal B is the group owner of the existing group to which terminal B belongs, step 607 is executed, and if terminal B is not the group owner of the existing group to which terminal B belongs, but is a client of the existing group, step 610 Is executed.

  Step 607: The terminal B encapsulates the Wi-Fi Direct configuration information of the existing group to which the terminal B belongs into an NFC connection handover response, and transmits the response to the terminal A.

  Step 608: The terminal A changes the value of the group owner intention in the Wi-Fi Direct configuration information of the terminal A to the group owner in the Wi-Fi Direct configuration information of the terminal B according to the Wi-Fi Direct configuration information of the existing group. Set a value smaller than the intended value. In this way, the terminal A can be used as a client because it joins the existing group to which the terminal B belongs.

  Step 609: The terminal B establishes a Wi-Fi Direct connection with the terminal A according to the existing group's Wi-Fi Direct configuration information.

  Step 610: The terminal B encapsulates the configuration information excluding the encryption information in the Wi-Fi Direct configuration information of the existing group and the description information of the group owner of the existing group into an NFC connection handover response, and sends the response Transmit to terminal A.

  Step 611: The terminal A requests the group owner for encryption information in the Wi-Fi Direct configuration information of the existing group according to the description information of the group owner, and the Wi-Fi Direct configuration of the existing group transmitted by the group owner. Receives encryption information in the session information.

  Specifically, the terminal A may request the encryption information from the group owner by a wireless connection (Wi-Fi or the like) method, or may acquire the encryption information by an additional touch (ie, , By establishing an NFC connection with the group owner). In this way, terminal A also obtains all Wi-Fi Direct configuration information of the existing group, and then step 612 is performed.

  Step 612: Terminal B establishes a Wi-Fi Direct connection with terminal A according to the Wi-Fi Direct configuration information of the existing group.

  Step 613: Terminal B determines whether terminal B has at least one unused MAC entity. If terminal B has at least one unused MAC entity, step 614 is performed. If terminal B does not have at least one unused MAC entity, that is, if terminal B determines that all MAC entities in terminal B are used, step 616 is performed.

  Step 614: Terminal B selects one of the unused MAC entities in terminal B as the MAC entity to be used by terminal B in the new group scheduled for creation, and Wi-Fi Direct for the new group scheduled for creation. Set configuration information.

  The Wi-Fi Direct configuration information of the new group scheduled to be created is consistent with the Wi-Fi Direct configuration information of the existing group to which the terminal B belongs. Specifically, when setting the Wi-Fi Direct configuration information of a new group to be created, the terminal B may use a part or all of the Wi-Fi Direct configuration information of the terminal A, For example, the group ID in the Wi-Fi Direct configuration information of the terminal A may be used as the identifier of the new group scheduled to be created, and / or the Wi-Fi Direct of the terminal A as the BSSID of the new group scheduled to be created. The group BSSID in the configuration information may be used, or new Wi-Fi Direct configuration information is set for a new group to be created without using the Wi-Fi Direct configuration information of the terminal A Shi It may be. As long as the Wi-Fi Direct configuration information of the new group scheduled to be created is consistent with the Wi-Fi Direct configuration information of the existing group to which the terminal B belongs, the present invention -The method of setting Fi Direct configuration information is not limited.

  Further, the Wi-Fi Direct configuration information of the new group scheduled to be created further includes the group information of the terminal A.

  Step 615: The terminal B encapsulates the Wi-Fi Direct configuration information of the new group scheduled to be created into an NFC connection handover response, transmits the response to the terminal A, and creates the Wi-Fi Direct of the new group scheduled to be created. A Wi-Fi Direct connection with terminal A is established according to the configuration information.

  Step 616: If the terminal B quits the existing group to which the terminal B belongs or prompts the user to use the terminal B, and the user using the terminal B selects to quit the existing group to which the terminal B belongs, step 617 Or if the user using terminal B chooses not to leave the existing group to which terminal B belongs, step 619 is executed.

  Step 617: The terminal B quits the existing group to which the terminal B belongs, and the Wi-Fi of the new group to be created according to the Wi-Fi Direct configuration information of the terminal B and the Wi-Fi Direct configuration information of the terminal A Direct configuration information is set.

  The Wi-Fi Direct configuration information of the new group to be created includes the identifier of the new group to be created, the BSSID of the new group to be created, the operation channel of the new group to be created, and the group owner intention of the terminal B The IP base address of the new group to be created, and the address of the MAC entity used by terminal B in the new group to be created.

  The value of the group owner intention of the terminal B is different from the value of the group owner intention of the terminal A in the Wi-Fi Direct configuration information of the new group to be created.

  Step 618: The terminal B encapsulates the Wi-Fi Direct configuration information of the new group to be created in an NFC connection handover response, transmits the response to the terminal A, and creates the Wi-Fi Direct of the new group to be created. A Wi-Fi Direct connection with terminal A is established according to the configuration information.

  Step 619: The terminal B returns a connection establishment failure response to the terminal A.

  Step 620: According to the default setting of terminal B, terminal B determines whether terminal B is requesting to join an existing group to which terminal A belongs. If terminal B requests to join an existing group to which terminal A belongs, step 621 is executed and terminal B joins the existing group to which terminal A belongs according to the default settings of terminal B If it is determined that a new group is created with terminal A, step 626 is executed.

  Step 621: According to the group information of the terminal A, the terminal B determines whether the terminal A is a group owner of an existing group to which the terminal A belongs. If terminal A is the group owner of the existing group to which terminal A belongs, step 622 is executed; if terminal A is not the group owner of the existing group to which terminal A belongs, but is a client of the existing group, step 623 Is executed.

  Step 622: The terminal B sets the value of the group owner intention in the Wi-Fi Direct configuration information of the terminal B to a value smaller than the value of the group owner intention in the Wi-Fi Direct configuration information of the terminal A. A Wi-Fi Direct connection with the terminal A is established according to the Wi-Fi Direct configuration information.

  In this step, the terminal B sets the value of the group owner intention in the Wi-Fi Direct configuration information of the terminal B to a value smaller than the value of the group owner intention in the Wi-Fi Direct configuration information of the terminal A. In this way, since the terminal B joins the existing group, the terminal B can be used as a client of the existing group to which the terminal A belongs.

  The Wi-Fi Direct configuration information of the terminal A is Wi-Fi Direct configuration information of the existing group to which the terminal A belongs.

  Step 623: The terminal B receives the description information of the group owner of the existing group to which the terminal A belongs, which is transmitted by the terminal A through the NFC connection.

  Specifically, the description information of the group owner of the existing group to which the terminal A belongs may be included in the Wi-Fi Direct configuration information of the terminal A, or the group owner of the existing group to which the terminal A belongs. Is also not included in the Wi-Fi Direct configuration information of the terminal A, and is transmitted to the terminal B together with the Wi-Fi Direct configuration information of the terminal A.

  In this case, the Wi-Fi Direct configuration information of the terminal A is configuration information excluding encryption information in the Wi-Fi Direct configuration information of the existing group to which the terminal A belongs.

  In the present embodiment, the description information of the group owner of the existing group to which the terminal A belongs may be transmitted together with the Wi-Fi Direct configuration information of the terminal A, or may be transmitted separately. It is not limited. That is, when the terminal A is a client of the existing group to which the terminal A belongs, the terminal A, in step 602, together with the description information of the group owner of the existing group to which the terminal A belongs to the terminal B via the NFC connection Wi-Fi Direct configuration information may be transmitted. For example, these two pieces of information may be encapsulated in an NFC connection handover request and the request may be transmitted to terminal B. The Wi-Fi Direct configuration information of terminal A is added to the NFC connection handover request, and the request is transmitted to terminal B in step 602. Then, the description information of the group owner of the existing group to which terminal A belongs is added to the NFC connection handover request. Or other In step 623, the message is transmitted to the terminal B via the NFC connection.

  Step 624: The terminal B requests the group owner for encryption information in the Wi-Fi Direct configuration information of the existing group to which the terminal A belongs according to the description information of the group owner of the existing group to which the terminal A belongs. The encrypted information in the Wi-Fi Direct configuration information of the existing group transmitted by (2) is received.

  Specifically, the terminal B may request the encryption information from the group owner by a wireless connection method, or may acquire the encryption information by additional touch (that is, establish an NFC connection with the group owner). By). In this way, terminal B also obtains all Wi-Fi Direct configuration information for the existing group, after which step 625 is executed.

  Step 625: Terminal B establishes a Wi-Fi Direct connection with terminal A according to the existing group's Wi-Fi Direct configuration information.

  Step 626: Terminal B determines whether terminal A has at least one unused MAC entity. If terminal A has at least an unused MAC entity, step 627 is executed. If terminal A does not have at least one unused MAC entity, that is, if terminal B determines that all MAC entities in terminal A are used, step 629 is performed.

  Step 627: Terminal B selects one of the unused MAC entities in terminal A and sets the Wi-Fi Direct configuration information for the new group to be created.

  The Wi-Fi Direct configuration information of the new group to be created further includes the address of the MAC entity selected by the terminal A to the terminal B, and the Wi-Fi Direct configuration information of the new group to be created is This is consistent with the Wi-Fi Direct configuration information of the existing group to which the terminal A belongs. Specifically, when setting the Wi-Fi Direct configuration information of a new group to be created, the terminal B may use a part or all of the Wi-Fi Direct configuration information of the terminal B, For example, the group ID in the Wi-Fi Direct configuration information of the terminal B is used as the identifier of the new group scheduled to be created, and / or the Wi-Fi Direct configuration information of the terminal B is used as the BSSID of the new group scheduled to be created. May use the group BSSID of the terminal B, or may not use the Wi-Fi Direct configuration information of the terminal B, and may provide new Wi-Fi Direct configuration information for a new group to be created. It may be constant. As long as the Wi-Fi Direct configuration information of the new group scheduled to be created does not conflict with the Wi-Fi Direct configuration information of the existing group to which the terminal A belongs, the present invention -The method for setting Fi Direct configuration information is not limited.

  Step 628: The terminal B encapsulates the Wi-Fi Direct configuration information of the new group to be created in an NFC connection handover response, transmits the response to the terminal A, and creates the Wi-Fi Direct of the new group to be created. A Wi-Fi Direct connection with terminal A is established according to the configuration information.

  In other implementations of this embodiment, steps 627 and 628 may also be as follows: That is, the terminal B sets Wi-Fi Direct configuration information of a new group scheduled to be created, and here, the Wi-Fi Direct configuration information of the new group scheduled to be created is stored in the existing group to which the terminal A belongs. There is no contradiction with the Wi-Fi Direct configuration information, and then the terminal B transmits Wi-Fi Direct configuration information of a new group to be created to the terminal A via the NFC connection. Terminal A then selects one of the unused MAC entities at terminal A and establishes a Wi-Fi Direct connection with terminal B according to the Wi-Fi Direct configuration information of the new group to be created. . When setting the Wi-Fi Direct configuration information of a new group to be created, the terminal B may use part or all of the Wi-Fi Direct configuration information of the terminal B. For example, The group ID in the Wi-Fi Direct configuration information of the terminal B may be used as the identifier of the new group, and / or the group in the Wi-Fi Direct configuration information of the terminal B as the BSSID of the new group to be created BSSID may be used, or new Wi-Fi Direct configuration information may be set for a new group to be created without using Wi-Fi Direct configuration information of terminal B.As long as the Wi-Fi Direct configuration information of the new group scheduled to be created does not conflict with the Wi-Fi Direct configuration information of the existing group to which the terminal A belongs, the present invention -The method of setting Fi Direct configuration information is not limited.

  Step 629: Terminal B transmits to terminal A a notification that terminal B is requesting to create a new group with terminal A.

  Step 630: The terminal A prompts the user who uses the terminal A to quit the existing group to which the terminal A belongs. When the user using the terminal A selects to stop the existing group to which the terminal A belongs, Step 631 is executed, and the user using the terminal A selects to stop the existing group to which the terminal A belongs Step 632 is executed.

  Step 631: The terminal A quits the existing group to which the terminal A belongs, and the Wi-Fi Direct configuration information of the terminal B and the Wi-Fi Direct configuration information of the terminal A, the Wi-Fi of a new group to be created Fi Direct configuration information is set, and Wi-Fi Direct connection with terminal B is established according to the Wi-Fi Direct configuration information of a new group to be created.

  After terminal A quits the existing group to which terminal A belongs, both terminal A and terminal B are not members of the existing group, so terminal A and terminal B are in accordance with the embodiment shown in FIG. A Wi-Fi Direct connection may be established according to the provided method. Details are not repeated here.

  Step 632: A Wi-Fi Direct connection cannot be established between terminal B and terminal A.

  In this embodiment, only one of terminal A and terminal B is a member of an existing group. If a member of an existing group is a group owner of an existing group to which the member belongs, the member may be used as a group owner or client in the new group to be created, and a member of the existing group belongs to the member If it is a client of an existing group, the terminal can be used only as a group owner in a new group to be created.

  In this embodiment, when the terminal A is a member of an existing group, the terminal A is a GO of the existing group to which the terminal A belongs, and the terminal B requests to join the existing group to which the terminal A belongs The format of the NFC connection handover request transmitted from the terminal A to the terminal B may be as shown in FIG. FIG. 7 is a schematic diagram of another embodiment of a format of a connection handover request according to the present invention.

  If terminal B is a member of an existing group, terminal B is a GO of an existing group to which terminal B belongs, and terminal A requests to join an existing group to which terminal B belongs, terminal B will The format of the connection handover response transmitted to A may be as shown in FIG. FIG. 8 is a schematic diagram of another embodiment of a format of a connection handover response according to the present invention.

  When the member of the existing group is a client of the existing group, the connection handover request shown in FIG. 7 or the connection handover response shown in FIG. 8 does not have authentication information or encryption information, and is a member of the existing group. It should be noted that FIGS. 4 and 5 may be referred to for the format of the connection handover request and the connection handover response when quits an existing group or when two terminals create a new group. Details are not repeated here.

  In the above embodiment, the terminal A and the terminal B exchange Wi-Fi Direct configuration information by using an NFC connection, and the device detection procedure and the GO negotiation procedure are implicitly included in the exchange process. By using wireless signaling, the Wi-Fi Direct connection establishment procedure is simplified without using handshake procedures such as device detection, GO negotiation, and WPS authentication information exchange defined in the Wi-Fi Direct protocol. Can be Furthermore, the Wi-Fi Direct protocol specifies that the client cannot actively detect other groups of GOs or clients. In this scenario, a Wi-Fi Direct connection cannot be established by utilizing wireless signaling, and this restriction does not exist when the technical means provided by this embodiment is utilized. As long as the terminal A and the terminal B are within the NFC communication range, the terminal A and the terminal B can exchange configuration information, and both of them are Wi-Fi Direct connection between the terminal A and the terminal B. Can be established.

  9A and 9B are flowcharts of yet another embodiment of a method for establishing a communication connection according to the present invention. As shown in FIGS. 9A and 9B, a method for establishing a communication connection may include:

  Step 901: Terminal A unlocks the screen, activates the NFC function, and also activates the NFC function, touches the terminal B that unlocked the screen, and then the NFC connection is between the terminal A and the terminal B. Established in

  Step 902: Terminal B receives terminal A's Wi-Fi Direct configuration information transmitted by terminal A via an NFC connection.

  In a specific implementation, terminal A and terminal B may use a “handover request conflict resolution mechanism” defined in the NFC connection handover protocol to determine the identifier of the Requester and Selector. However, the present embodiment will be described by using as an example that the terminal A is a Requester and the terminal B is a Selector.

  In the present embodiment, the Wi-Fi Direct configuration information of the terminal B includes the group information of the terminal B.

In this embodiment, the Wi-Fi Direct configuration information of the terminal B further includes the group owner intention of the terminal B, the number of MAC entities in the terminal B, and the address of each MAC entity. Here, the group information of the terminal B The value of is that terminal B is not a member of an existing group, that terminal B is a group owner of an existing group to which terminal B belongs, or that terminal B is a client of an existing group to which terminal B belongs. You can,
The Wi-Fi Direct configuration information of the terminal A includes group information of the terminal A. The Wi-Fi Direct configuration information of the terminal A further includes the group owner intention of the terminal A, the number of MAC entities in the terminal A, and each Having the address of the MAC entity, where the value of the group information of terminal A is that terminal A is not a member of an existing group, terminal A is a group owner of an existing group to which terminal A belongs, or terminal A may be a client of an existing group to which terminal A belongs.

  Step 903: According to the group information of terminal B and the group information of terminal A, terminal B determines that both terminal B and terminal A are members of an existing group.

  Step 904: The terminal B determines whether the terminal B and the terminal A belong to the same group according to the Wi-Fi Direct configuration information of the terminal B and the Wi-Fi Direct configuration information of the terminal A. If terminal B and terminal A belong to the same group, step 905 is executed, and if terminal B and terminal A do not belong to the same group, step 906 is executed.

  Specifically, since the terminal B determines whether the terminal B and the terminal A belong to the same group, the group ID, the group BSSID, and the GO MAC in the Wi-Fi Direct configuration information of the terminal B and the terminal A are determined. If the address, IP base address, etc. are the same, and the group ID, group BSSID, GO MAC address, IP base address, etc. in the Wi-Fi Direct configuration information are all the same, terminal B and terminal A Can be determined to belong to the same group, otherwise terminal B and terminal A can be determined not to belong to the same group.

  Step 905: The terminal B transmits to the terminal A a message indicating that the terminal B can directly communicate with the terminal A.

  Specifically, when both terminal B and terminal A are clients, communication may be executed by using GO, or directly by using GO to execute communication. If a data connection is established and one of terminal B and terminal A is GO and the other is a client, the communication may be performed directly.

  Step 906: The terminal B determines whether at least one of the terminal B and the terminal A is a group owner according to the group information of the terminal B and the group information of the terminal A. If at least one of terminal B and terminal A is a group owner, step 907 is executed, and if neither terminal B nor terminal A is a group owner, that is, both terminal B and terminal A are existing groups If so, step 910 is executed.

  Step 907: Terminal B determines whether both Terminal A and Terminal B have at least one unused MAC entity, and if Terminal A and Terminal B have at least one unused MAC entity, Step If 908 is executed and all MAC entities in terminal A and / or terminal B are utilized, step 910 is executed.

  Step 908: Terminal B selects one from the unused MAC entity at terminal B as the MAC entity to be used by terminal B in the new group to be created, and 1 from the unused MAC entity at terminal A. And set Wi-Fi Direct configuration information for a new group to be created.

  The Wi-Fi Direct configuration information of the new group to be created may further include the address of the MAC entity selected by terminal B from terminal A.

  In this example, if only one of terminal B and terminal A is a group owner in an existing group, the terminal that is the group owner in the existing group must be a client in the new group, The group owner intention must be set to be smaller than the peer end group owner intention in the Wi-Fi Direct configuration information of the new group, and both terminal B and terminal A are group owners in the existing group. In this case, the group owner intention of the two terminals in the new group configuration information may be set randomly as long as the values of the group owner intention of the two terminals are set differently.

  Step 909: The terminal B encapsulates the Wi-Fi Direct configuration information of the new group to be created in an NFC connection handover response, transmits the response to the terminal A, and creates the Wi-Fi Direct of the new group to be created. A Wi-Fi Direct connection with terminal A is established according to the configuration information.

  Step 910: The terminal B prompts the user who uses the terminal B to stop the existing group to which the terminal B belongs, and instructs the terminal A to prompt the user who uses the terminal A to stop the existing group to which the terminal A belongs. .

  Step 911: After the user using terminal B chooses to quit the existing group to which terminal B belongs and / or after the user using terminal A chooses to quit the existing group to which terminal A belongs, The terminal B establishes a Wi-Fi Direct connection with the terminal A according to the Wi-Fi Direct configuration information of the terminal that does not quit the existing group to which the terminal belongs or the Wi-Fi Direct configuration information of the new group to be created. To do.

  In this embodiment, when the terminal B or the terminal A not only secures the initial connection but also establishes a new connection, the terminal cannot be used as a client in both of the two groups. Specifically, if the terminal is used as a client in the initial connection, the terminal needs to be used as a group owner in the new connection, and if the terminal is used as a group owner in the initial connection, the terminal Can be used as a group owner or client in a new group.

  Specifically, when the user using terminal B chooses to quit the existing group to which terminal B belongs, or when the user using terminal A chooses to quit the existing group to which terminal A belongs Terminal A and Terminal B may establish and communicate with a Wi-Fi Direct connection by utilizing the method provided by the embodiments shown in FIGS. 6A, 6B, 6C and 6D of the present invention. . That is, if the user using terminal B chooses to quit the existing group to which terminal B belongs, and the user using terminal A also chooses to quit the existing group to which terminal A belongs, terminal A and terminal B may communicate by establishing a Wi-Fi Direct connection by utilizing the method provided by the embodiment shown in FIG. 3 of the present invention. Details are not repeated here.

  In this embodiment, since terminal A forms a new group, when establishing an inter-group connection with terminal B, the formats of the connection handover request used and the connection handover response used are shown in FIGS. 10 and 11, respectively. As shown in FIG. FIG. 10 is a schematic diagram of still another embodiment of the format of the connection handover request according to the present invention, and FIG. 11 is a schematic diagram of still another embodiment of the format of the connection handover response according to the present invention.

  In the above embodiment, the terminal A and the terminal B exchange Wi-Fi Direct configuration information by using the NFC connection, and the device detection procedure and the GO negotiation procedure are implicitly included in the exchange process. As a result, a Wi-Fi Direct connection establishment procedure is performed without using handshake procedures such as device detection, GO negotiation, and WPS authentication information exchange, which are executed by using wireless signaling and defined in the Wi-Fi Direct protocol. It can be simplified. Furthermore, the Wi-Fi Direct protocol specifies that the client cannot actively detect other groups of GOs or clients. In this scenario, the Wi-Fi Direct connection cannot be established by utilizing wireless signaling, and there is no such restriction when the technical means provided by this embodiment is utilized. As long as the terminal A and the terminal B are within the NFC communication range, the terminal A and the terminal B can exchange configuration information, and both can establish a Wi-Fi Direct connection between the terminal A and the terminal B. .
