Problems solved by technology

[0005]Currently, only wide area group technology is used to realize closed group services across exchanges. Generally, SHLR and tandem office are used to cooperate, or the service authentication server cooperates with tandem office to realize , and it is necessary to restrict data at each originating office to prevent calls outside the user group, which is not conducive to centralized management by operators

Embodiment Construction

[0040] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0041] In existing applications, the closed group service is generally realized through the cooperation of the SHLR and the tandem office, or the cooperation of the service authentication server and the tandem office. However, the present invention organically combines the two methods, fully utilizes the advantages of the two methods, and increases the flexibility and high efficiency of service configuration. The specific connection method is as figure 1 As shown, the tandem office is connected to the SHLR through the MAP+ protocol, the service authentication server and the tandem office establish communication through the TCP / IP protocol, and the end office and the tandem office use ISUP (Integrated Digital Service Network User Part) standard relay interconnection .

Abstract

This invention provides a system of realizing close group service including a junction center, a SHLR, a service authentication server and an end office, in which, the junction center is connected with the SHLR via the MAP +protocol and sets up communication with the service authentication server by the TCP / IP protocol and is mutual-connected with the standard relay of the end office ISUP. This invention also provides a method for realizing said service including: after a user in the group initiates a call, if the junction center judges that the called number is a small number in a WAN group,it plugs a WAN group access code before it and sends it to the SHLR, otherwise, it sends the number to the SHLR directly, which returns the response information to the junction center and allows thistime of call if it judges that the calling user has signed the close group service and a WAN group access code is plugged before the called number, it carries out the next step, otherwise it informs the junction center to refuse the call to continue successive calls.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing closed group service. Background technique [0002] With the continuous development of fixed-line services, the majority of users have put forward higher requirements for closed group services. Users in the group not only require the ability to make calls across exchanges, but also require services such as color ringing and simultaneous ringing. [0003] Closed group service features: users in the group are only allowed to make calls within the group and use 201 card services. [0004] Mobile application part MAP+ technical features: all calls from the end office are sent to the tandem office for unified processing. After processing, continue to be called. Using the MAP+ technology, services such as calling CRBT, calling prepaid, called one number, and called CRBT can be realized. [0005] At present, the only technology for realizing closed group services ac...
