The connector 107 is used for connection between the first call unit 105 and the second call unit 106 and the first baseband unit 103 and the second baseband unit 104 .

For example, when the first call unit 105 is connected to the first baseband unit 103, the user can use the first call unit 105 to make a call with the first mobile phone card. When the second call unit 106 is connected with the second baseband unit 104, the user can use the second call unit 106 to make a call with the second mobile phone card. In this way, the user can simultaneously use the first call unit 105 and the second call unit 106 to make calls between the first mobile phone card and the second mobile phone card.

The communication controller 108 controls the connection state of the communication device 107 . In other words, the connecter 107 is controlled to realize different connection states between the first call unit 105 and the second call unit 106 and the first baseband unit 103 and the second baseband unit 104 . Specifically, when a baseband unit in the first baseband unit 103 and the second baseband unit 104 receives an incoming call or initiates an outgoing call to establish a call, the connection controller 108 connects the baseband unit to the first call unit 105 and one of the second call unit 106 that is in an idle state to make a call. The idle state here refers to not being connected to the first baseband unit 103 or the second baseband unit 104 . In addition, when the call ends, the connectivity controller 108 disconnects the baseband unit from the call unit.

Fig. 2 shows a flowchart of a call control method according to an exemplary embodiment of the present invention.

In step 201, the connectivity controller 108 receives a request from one of the first baseband unit 103 and the second baseband unit 104 to connect to the talk unit. When one of the first baseband unit 103 and the second baseband unit 104 has an incoming or outgoing call, the baseband unit where the call occurs requests the connection controller 108 to connect to the call unit.

In step 202, the connectivity controller 108 determines whether both the first talk unit 105 and the second talk unit 106 are in an idle state. It can be determined whether the connector 107 connects the first baseband unit 103 to the first talk unit 105 and the second talk unit 106, and determines whether the connector 107 connects the second baseband unit 104 to the first talk unit 105 and the second talk unit. unit 106 to determine whether both the first call unit 105 and the second call unit 106 are in an idle state.

When the connector 107 does not connect the first baseband unit 103 to the first communication unit 105 and the second communication unit 106, and it is determined that the connector 107 does not connect the second baseband unit 104 to the first communication unit 105 and the second communication unit 106 , it is determined that both the first call unit 105 and the second call unit 106 are in an idle state. Otherwise, it is determined that neither the first call unit 105 nor the second call unit 106 is in an idle state.

When it is determined in step 202 that the first call unit 105 and the second call unit 106 are in an idle state, in step 203, the connection controller 108 controls the connecter 107 to connect the one baseband unit to the first call unit 105 and the second call unit 105. One of the talking units 106 .

Optionally, the connection controller 108 may make an output interface (for example, a display, a speaker) of the mobile communication terminal notify the user to select a call unit from the first call unit and the second call unit. For example, displaying a user interface for the above selection on the display; or notifying the user to press a predetermined key to make the selection through a loudspeaker. In addition, the connectivity controller 108 may receive a user's selection from an input interface (eg, keypad, buttons, touch screen) of the mobile communication terminal. When the user selects the first call unit 105, the connection controller 108 controls the connecter 107 to connect the one baseband unit to the first call unit 105; when the user selects the second call unit 106, the connection controller 108 controls the connecter 107 The one baseband unit is connected to the second talk unit 106 .

When it is determined in step 202 that the first call unit 105 and the second call unit 106 are not in an idle state, in step 204, the connection controller 108 controls the connecter 107 to connect the one baseband unit to the first call unit 105 and the second call unit 105. A call unit in an idle state among the two call units 106 . It should be understood that when the first call unit 105 and the second call unit 106 are not both in the idle state, the call unit in the non-idle state is connected to another baseband unit for the call of the other baseband unit. In addition, since the same baseband unit is not connected to two talk units at the same time, there is one talk unit in an idle state because the one baseband unit has not yet established a connection with the talk unit.

In addition, when the connection controller 108 simultaneously receives a request from one of the first baseband unit 103 and the second baseband unit 104 to connect to the communication unit, it can control the connection unit 107 to connect the first baseband unit 103 to the first communication unit. One of the first talk unit 105 and the second talk unit 106 connects the second baseband unit 104 to the other of the first talk unit 105 and the second talk unit 106 .

In addition, the connection controller 108 can make the output interface of the mobile communication terminal notify the user to select the talk unit for the first baseband unit 103 and the second baseband unit 104 respectively, and can receive the user's selection from the input interface of the mobile communication terminal. Subsequently, the connectivity controller 108 can respectively connect the first baseband unit 103 and the second baseband unit 104 to the talk unit selected by the user.

In addition, when the call of the first baseband unit ends and the call of the second baseband unit does not end, the connection controller 108 controls the connecter to disconnect the connection between the first baseband unit and the currently connected call unit, and through The output interface of the mobile communication terminal notifies the user that another talk unit (ie, the talk unit disconnected from the first baseband unit) is available. When receiving from the input interface of the mobile communication terminal that the user selects another talk unit for the second baseband unit, the connection controller 108 controls the connecter to connect the second baseband unit to the other talk unit.

FIG. 3 shows an example of the connector 107 in the mobile communication terminal shown in FIG. 1 according to an embodiment of the present invention.

In this embodiment, the communication device 107 includes two communication switches, namely, a first communication switch 301 and a second communication switch 302 .

One connection end of the first connecting switch 301 is a fixed end, which is fixedly connected to the first baseband unit 103; the other connecting end of the first connecting switch 301 is a moving end, which can be connected to the first communication unit 105 or the second communication unit 106 is either at zero (ie not connected to any talk unit).

One connection end of the second connection switch 302 is a fixed end, which is fixedly connected to the second baseband unit 104; the other connection end of the second connection switch 302 is a dynamic end, which can be connected to the first communication unit 105 or the second communication unit 106 is either at zero (ie not connected to any talk unit).

The control ends of the first connection switch 301 and the second connection switch 302 are connected to the connection controller 108 , so that they are in different connection states under the control of the connection controller 108 .

Each connecting switch can be in three kinds of connecting states, that is, (1) the moving end is connected to the first talking unit 105; (2) the moving end is connected to the second talking unit 106; (3) the moving end is not connected to the first talking unit 105 and any one of the two talk units 106 (ie, at zero).

A connectivity switch in state (1) or state (2) indicates that a voice connection is established. Therefore, generally speaking, the first connection switch 301 and the second connection switch 302 are not in state (1) or state (2) at the same time. In other words, a talk unit will not be connected to two baseband units at the same time. However, the first connection switch 301 and the second connection switch 302 can be in the state (3) at the same time, which indicates that both baseband units have established a voice connection and are in a mute state or that both baseband units have not established a voice connection.

Usually, when the mobile communication terminal is turned on, the connection controller 108 sets the connection state of the first connection switch 301 and the second connection switch 302 to state (3) by default.

During the standby process of the mobile communication terminal, when there is an incoming call or an outgoing call (that is, a call needs to be established) in a certain baseband unit, the connection controller 108 sets the connection state of the connection switch of the baseband unit to state (1) or State (2), thereby establishing the connection between the baseband unit and the communication unit. When a certain baseband unit terminates the call or the user selects the silent mode during the call, the connection state of the connection switch of the baseband unit 108 is set to state (3) by the connection controller 108, thereby disconnecting the connection between the baseband unit and the call unit connect.

The call control method of the mobile communication terminal shown in FIG. 1 and FIG. 3 according to an embodiment of the present invention will be described below with reference to FIG. 4 . Fig. 4 shows a flowchart of a call control method according to an exemplary embodiment of the present invention.

As shown in FIG. 4 , in step 401 , when there is an incoming or outgoing call from one of the first baseband unit 103 and the second baseband unit 104 , the baseband unit that has the call requests the connection controller 108 to connect to the call unit. At this time, the connectivity controller 108 may receive a request from the baseband unit to connect to the talk unit.

In step 402 , in response to a request from the baseband unit to connect to the talk unit, the connectivity controller 108 queries the connection statuses of the first connectivity switch 301 and the second connectivity switch 302 . That is, it is determined whether the connection states of the first connection switch 301 and the second connection switch 302 are both in state (3).

When it is determined in step 402 that the connection states of the first connection switch 301 and the second connection switch 302 are all in state (3), in step 403, the connection controller 108 connects the first connection switch 301 and the second connection switch 302 with The connection state of the corresponding connection switch of the baseband unit is set to state (1) or state (2). For example, if the first baseband unit 103 receives an incoming call or initiates an outgoing call, the connection controller 108 sets the connection state of the first connection switch 301 to state (1) or state (2); for example, if the second baseband When the unit 104 receives an incoming call or initiates an outgoing call, the connection controller 108 sets the connection state of the second connection switch 302 to state (1) or state (2).

In another embodiment, when it is determined in step 402 that the connection states of the first connection switch 301 and the second connection switch 302 are both in state (3), the connection controller 108 may make the output interface of the mobile communication terminal (for example, a display , loudspeaker) to notify the user to select a call unit from the first call unit and the second call unit. For example, displaying a user interface for the above selection on the display; or notifying the user to press a predetermined key to make the selection through a loudspeaker. In addition, the connectivity controller 108 may receive a user's selection from an input interface (eg, keypad, buttons, touch screen) of the mobile communication terminal. When the user chooses to use the first communication unit 105, the connection controller 108 sets the connection state of the corresponding connection switch to state (1); when the user chooses to use the second communication unit 106, the connection controller 108 sets the connection state of the corresponding connection switch to The state is set to state(2).

In addition, when the user selects the silent mode during a call, the connectivity controller 108 may set the connectivity state of the corresponding connectivity switch to state (3).

When it is determined in step 402 that the connected states of the first connected switch 301 and the second connected switch 302 are not all in state (3), in step 404, the second connecting end of the corresponding connected switch is connected to the first call unit 105 and one of the second call units 106 that is in an idle state.

In another embodiment, one connection end of the first connection switch 301 shown in FIG. 3 is a fixed end, which is fixedly connected to the first communication unit 105; Either connected to the first baseband unit 103 or the second baseband unit 104 or in the null position (ie not connected to any baseband unit).

One connection end of the second communication switch 302 is a fixed end, which is fixedly connected to the second call unit 106; the other connection end of the second connection switch 302 is a dynamic end, which can be connected to the first baseband unit 103 or the second baseband unit 104 is either in null position (ie not connected to any baseband unit).

It should be understood that connecters with other structures are also feasible, as long as the first baseband unit 103 and the second baseband unit 104 can be connected with the first call unit 105 and the second call unit 106 under the control of the connect controller 108, and a The baseband unit is not connected to the first talk unit 105 and the second talk unit 106 at the same time.

According to the mobile communication terminal and the call control method of the present invention, two mobile phone cards can be used for calling at the same time, which overcomes the limitation that only one mobile phone card can be used for calling.

While the invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that changes may be made in form and detail without departing from the spirit and scope of the invention as defined by the claims. various changes.
