Detailed ways

The networking of the system of the embodiment of the present invention is shown in Figure 1, by the service control point equipment (SCP), the service switching point equipment (SSP) of the PHS switching network and the fixed switch that the AP belongs to, the dual-mode mobile phone access point equipment (AP) ), a PHS network dual-mode mobile phone, etc., and the figure also shows the way that the dual-mode mobile phone is connected to the SSP through the wireless network it belongs to. Among them, there is a No. 7 signaling link between the SCP and the SSP, which is used for transmitting intelligent network signaling messages. There is a voice channel link between the SSP and the fixed switch, and the AP is connected to the fixed switch through the voice channel, and has the function of serving as a terminal of the fixed switch. The networking mode in the figure and the communication protocol adopted between each device (TUP/CAP/WLAN shown in the figure) have been widely used in the live network.

In order to illustrate the device functions and business processes of this embodiment, the "service user" and "access point user (AP user)" are described first.

A dual-mode mobile phone number uniquely represents a "service user" of the present invention, and this service user phone can be a PHS bluetooth phone, PHS WLAN phone or other network phone or the like. Service users need to sign up for the calling process of the intelligent network and the called process of the intelligent network on the SSP.

A local phone number uniquely represents an "AP user" (AP device), which is a device used to provide dual-mode mobile phone access.

The dual-mode mobile phone of the present embodiment is the bluetooth telephone in the dual-mode mobile phone of PHS network, and this " bluetooth PHS telephone " can be connected to PHS switching network by PHS wireless agreement, PHS wireless equipment, also can pass bluetooth protocol interface (or WLAN protocol , or other short-range wireless communication protocols) to connect to the AP device, initiate or receive calls;

The AP device establishes a connection with the dual-mode mobile phone through the Bluetooth protocol, connects with the home switch through the voice channel, and exchanges signals in the communication link to realize functions such as voice calls. In this embodiment, the AP also has a dial processing module and a connection processing module related to the service of the present invention, wherein:

The dialing processing module is configured to dial to the SSP after detecting that the connection with the dual-mode mobile phone is established or disconnected, or after receiving a call from the dual-mode mobile phone. In the call initiated by the AP, the caller is based on the AP number, but the service of the present invention also needs to know the number of the dual-mode mobile phone, the information registered on the access point device of the dual-mode mobile phone, and the routing information, so this embodiment , the call processing module transforms the called number, and dials to the service switching point device by adding "number prefix + instruction category number + instruction parameter" before the called number. Among them, the number prefix is represented by N1, which needs to be specified in advance, and is used for routing, addressing and other operations; the instruction category number is a number with a length of one digit, "1" means to register a dual-mode mobile phone-AP device binding, "2 "Indicates the release of a dual-mode mobile phone-AP device binding, "3" indicates that the registered dual-mode mobile phone is used as the calling party; the command parameter is represented by X, which is the serial number assigned by the registered mobile phone number in the AP, and the range is 00 -99. The length of N1 is fixed, and the length of the command number is also fixed. The total length of "number prefix + command number + command parameter" is limited by the capabilities supported by the switch. In addition, the AP password needs to be added to the number dialed when the dual-mode mobile phone is detected to be connected or disconnected.

The connection processing module is used for finding the dual-mode mobile phone to be connected when receiving the connection message from the SSP. Since the called number in the call from the SSP to the AP is the number of the AP, the AP needs to determine the dual-mode mobile phone to be connected according to the registration serial number of the dual-mode mobile phone carried in the calling parameter.

The fixed switch is used to analyze the number prefix in the AP call, and route the call to the SSP of the PHS switching network. Number analysis is the basic capability of the switch, and it only needs to configure the corresponding data on the management console of the switch.

In addition to the original functions, the SSP needs to load an intelligent network service triggering module specially used in the present invention to support the user in the present invention to trigger the intelligent network service on the SCP in a subscription manner.

In addition to the original functions of the SCP, an intelligent network service module and a user management module need to be added. in:

The intelligent network service module is used to provide various services of the present invention, and further includes: a registration processing unit, a deregistration processing unit, a calling process processing unit and a called process processing unit:

The registration processing unit is used to record the association relationship between the AP number, the dual-mode mobile phone number and the registration serial number of the dual-mode mobile phone in the AP after the AP that initiated the registration passes the authentication, issue a bill and play a prompt voice. If the dual-mode mobile phone has already been registered, the original registration relationship will be canceled first.

The deregistration processing unit is used to cancel the registration of the dual-mode mobile phone on the AP after passing the authentication of the AP that initiated the deregistration, or when the dual-mode mobile phone makes an outgoing call through its home network and has registered with the AP, issues a bill and Play prompt voice.

The calling process processing unit is used to determine the calling number of the dual-mode mobile phone according to the registration record after receiving the call from the dual-mode mobile phone through the AP, and use it as the calling number in the connection message for connection.

The called process processing unit is used to add the number prefix and the registration number of the called party on the AP to the calling parameter of the connection message according to the registration record when the calling party dials a dual-mode mobile phone number registered to the AP. Fill in the phone number of the AP in the call parameter to connect.

The user management module is used to manage the data and registration situation of service users (referring to PHS bluetooth phone) and AP users in the database, further comprising:

The business user management unit is used to add new business users in the database of the system, such as PHS bluetooth phones; query and delete business users in the system; modify the attributes of business users in the system, such as account opening date, validity period, and owner information etc.

The AP user management unit is used to add new AP users in the database of the system; query and delete the AP users in the system; modify the attributes of the AP users in the system, such as passwords, etc. In particular, each AP user has a non-empty password. When the AP registers a dual-mode mobile phone, it must provide the password to the SCP. The SCP authenticates the AP. If the password is incorrect, the connection between the AP and the dual-mode mobile phone cannot be registered on the SCP. relation.

The user registration management unit is used to add or delete related records in the system database (including dual-mode mobile phone numbers, AP phone numbers, and registration of dual-mode mobile phones in APs) relationship between serial numbers), query and so on.

In this embodiment, the above-mentioned user management module is implemented through a newly added data management and maintenance terminal connected to the SCP, which is also a component of the SCP. The software on the operation and maintenance terminal can modify the data in the SCP database.

When using the method of the present invention, the service user needs to first sign up for the intelligent network calling process and the intelligent network called process on the SSP. In this embodiment, after the dual-mode mobile phone is registered to the AP through the Bluetooth protocol, within the effective communication range of Bluetooth, the user can repeatedly call in or out. registration, dual-mode mobile phone registration returns to the network.
