Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

The present invention is explained by taking the bluetooth phone in the PHS (Little Smart) network dual-mode dual-machine as an example. Among them, the "Bluetooth PHS phone" has the function of connecting to the PHS switching network through the PHS wireless protocol and PHS wireless equipment, and also has the function of connecting to the access device HOMEBOX through the Bluetooth protocol interface (the HOMEBOX can be connected to the PSTN network).

As shown in Figure 1, the communication system of the present invention consists of intelligent network service control point equipment (SCP), mobile exchange/service switching point equipment (SSP), home location register (HLR) and fixed exchange of PSTN network, dual-mode telephone interface Into the device (also known as HOMEBOX, cordless telephone landline, in the PHS network, called PHS cordless telephone landline) and dual-mode mobile phone. The SCP is the core component of the intelligent network and the control point of business logic and data collection in the intelligent network. It includes two parts: business control function and business data function. The SSP is mainly responsible for call control and service exchange, and interfaces connected with other functional entities are set on it to obtain additional information. The SSP is located at the end office. The home location register is used to store the basic service and supplementary service data of the mobile user, especially the service data of the intelligent network, and the control point device is connected with the home location register of the mobile network to which the dual-mode mobile phone belongs. The service control point equipment and the service exchange point equipment are connected through the No. 7 signaling link, which is used to transmit intelligent network signaling messages such as CAP (CAMEL Application Part,) messages. The service control point equipment and the HLR equipment are also connected through the No. 7 No. signaling link connection for transmitting MAP (Mobile Application Part) messages. The service switching point device has the function of supporting the intelligent network service of the present invention. The service switching point device can support triggering the intelligent network service according to the called number segment. There is a voice channel link between the exchange point and the fixed exchange, and the HOMEBOX is connected to the fixed exchange through the voice channel, that is, the HOMEBOX has the function of serving as a terminal of the fixed exchange. The fixed exchange can connect the call with a special prefix (the call that needs to be transmitted by the intelligent network) dialed by HOMEBOX to the switching network to which the dual-mode mobile phone belongs, and the service switching point of the switching network to which the dual-mode mobile phone belongs triggers the service to the service control point. The HOMEBOX and the dual-mode mobile phone can use Bluetooth protocol, WLAN protocol, PHS protocol, etc. to communicate to transmit data, voice and other messages, and the dual-mode mobile phone becomes a sub-machine of the HOMEBOX. The service control point of the present invention also has the functions of registering the dual-mode mobile phone to the HOMEBOX and completing network access authentication or deregistration, and HOMEBOX registration to the SCP or deregistration, thereby completing the authentication of the dual-mode mobile phone network access and HOMEBOX status registration. The "HOMEBOX service" item is added to the mobile phone user (dual-mode mobile phone) data item on the HLR, which records whether the HOMEBOX service of the dual-mode mobile phone has been activated, the SCP address at the time of authentication and other parameters, and can control the service through MAP messages These parameters are passed between control points.

In the present invention, HOMEBOX is also referred to as a PHS telephone landline; a dual-mode mobile phone is also referred to as a sub-unit of a PHS telephone landline, and the dual-mode mobile phone has a terminal identification (physical number PS_NUM). A PSTN phone number uniquely identifies a HOMEBOX. HOMEBOX has the function of automatically sending the number prefix. When the present invention communicates, a number prefix (N1) must be specified in advance, and the HOMEBOX device calls the mobile switch by calling "number prefix + command number + command parameter", and finally the SCP is responsible for completing the recording of the dual-mode phone to the HOMEBOX device Binding, unbinding of dual-mode phone to HOMEBOX device and recording the registration status of HOMEBOX device. The switching network connects the call to the SSP of the mobile switching network, and the SSP triggers the intelligent network service on the SCP. The length of N1 is fixed, and the length of "command number" is also fixed. The total length of "number prefix + command number + command parameter" can be limited by the capability of the switch. For each HOMEBOX user, set a non-empty password with a fixed length. When the HOMEBOX registers the dual-mode phone, it can be provided to the SCP, and the SCP will authenticate the HOMEBOX: if the password is incorrect, the connection relationship between the HOMEBOX and the dual-mode phone cannot be registered on the SCP. Similarly, for a dual-mode mobile phone, a corresponding password can also be set for authentication.

When a dual-mode mobile phone enters the HOMEBOX wireless signal control area, HOMEBOX first assigns an extension number to the dual-mode mobile phone, and initiates an intelligent network service activation registration request to the service switching point through the PSTN end office. The specific registration/deregistration process of the present invention will be described in detail below.
