Problems solved by technology

The latest standard of the third-generation mobile communication also uses the SIP protocol to realize the IP-based mobile communication subsystem, but it has not been commercialized on a large scale.
If the existing SIP protocol is used to use the fixed telephone to realize the communication among the branches of an enterprise, on the one hand, the fixed telephone will bring a lot of inconvenience, and on the other hand, the high telephone fee will also become a burden on the enterprise

Embodiment Construction

[0042] The present invention combines an extended SIP protocol (abbreviated as S-PHS protocol) with PHS technology, and provides a low-cost and fast method for realizing wide-area distribution wireless group telephones. The method uses figure 1 The networking structure shown, the following describes the various networking devices and their functions as follows:

[0043] One S-PHS registration and redirection server: This server is located in the Internet protocol IP backbone network, and stores the location information and authentication information of all PHS wireless PBX users. The server software is modified on the SIP registration and redirection server software, and supports the saving and updating of PHS user information. It accesses the IP backbone network through the TCP / IP protocol, and communicates with several S-PHS proxy servers through the S-PHS protocol.

[0044] Several S-PHS proxy servers: Set up several S-PHS proxy servers located in the backbone network acc...

Abstract

A distributing wireless group phone realized method is disclosed, which is realized by S-PHS protocol and PHS technique, S-PHS registration and redirection server accesses the base station of PHS and mobile communication via the S-PHS gateway, and the registration route includes: (a) when the terminal of PHS is open or move to different paging district, the base station sends the registration messages to S-PHS via S-PHS gateway, and the S-PHS gateway stores the user information in registration messages; (b) S-PHS registration and redirection server generates the discriminated random number and calculates the discriminated result, and sends the responds message to the S-PHS gateway; (c) S-PHS gateway processes the discrimination, if the discrimination passed, S-PHS gateway sends registration message to S-PHS registration and redirection server again; (d) after S-PHS registration and redirection server receives the second registration message, it refreshes user information, and returns the response message of successful registration. The invention can realize cheap mobile communication between the branches with long distant geographic position of one company.

Description

technical field [0001] The invention relates to a distributed wireless group telephone system and its realization method. Background technique [0002] The function of the existing SIP (Session Initiation Protocol, Session Initiation Protocol) protocol is to establish, modify, and release the session of one or more participants. Because it is simple, flexible, easy to expand, and supports mobility, it has become a recognized future in the industry. An important signaling protocol for building an all-IP mobile communication core network. However, it is still far away from the emergence of the all-IP core network, because it involves the investment protection of existing operators' equipment and unified billing issues. At present, the SIP protocol is mainly used for VoIP (Voice over IP, IP voice technology) operators to provide fixed-line telephone services for VoIP terminal users. The latest standard of the third generation of mobile communication also uses the SIP protocol...
