A method and communication system for realizing wide-area group service

Abstract

The present invention provides a method and communication system for achieving wide area group service, keeping signal and logic number of group user and corresponding small number of the wide area group on the home location register of the exchanging equipment communication in multiple switched network; when the calling side exchanging equipment receiving the call request of the wide area group service, if judging called being other group user, sponsoring inquiry request to the home location register, carrying the called small number of and calling logic number inquired in the local; the home location register determining the group number of wide area group of the calling after receiving inquiry request, and determining called logic number by combining the called small number, then requesting the called routing number and returning to the calling side exchanging equipment; the calling side exchanging equipment routing to the called exchanging equipment by the routing number and completing the call. The system and method of the invention achieves the wide area group service on the basis of utilizing the present equipment in the network as possible.

Description

technical field [0001] The present invention relates to a wide-area group service realization in the field of communication network, more specifically, relates to a method and a communication system for realizing the wide-area group service. Background technique [0002] With the continuous integration of communication networks, wide area group users (or large business group users) will not only span multiple switching networks, but also have multiple types of networks at the same time, such as fixed networks, PHS networks, and mobile networks. [0003] At present, there are mainly the following methods to provide wide area group services: [0004] One is: through the introduction of intelligent service platforms or other server platforms, this method requires additional equipment and increases operating costs, and the group services realized by the original switching equipment cannot be provided. [0005] The other is: each switching device stores the number correspondence...

Problems solved by technology

[0004] One is: through the introduction of intelligent service platforms or other server platforms, this method requires additional equipment and increases operating costs, and the group services realized by the original switching equipment cannot provide

[0005] The other is: each switching device stores the number correspondence data of all business group users including other office group users, and each switching device can query this part of the data locally; this method has many switching devices on the existing network, It is difficult to implement such a data storage and query function on all switching devices of all manufacturers, and the modification of group user data needs to be modified by all related switching devices, especially when crossing different networks, it is difficult to implement and maintain, and it is not operable
