Method for detecting telephone subscriber in same gateway/gateway controller equipment

Abstract

The disclosed method to detect telephone user on same gateway / gateway controller comprises: building communication link between the calling and called, A. the gateway / controller of the calling monitors the detection information from the gateway / controller of the called; B. the gateway / controller of the calling decides whether they are the same device, yes to decide the calling and called belong to one gateway / gateway controller, v.v.

Description

technical field [0001] The invention relates to a technology for detecting telephone users in an Internet Protocol (IP) network, in particular to a method for detecting that the telephone users are in the same gateway / gateway controller device. Background technique [0002] With the rapid development of the IP network, it becomes possible to provide cheap and high-quality voice and data services on the IP network, so the IP network is increasingly concerned by telecommunication equipment manufacturers and operators. Telecommunication equipment manufacturers have also introduced a variety of gateway / gateway controller equipment to meet the flexible and changeable networking requirements of operators. [0003] In the current IP network networking, telephone users directly or indirectly access the gateway / gateway controller device, but the management functions of these telephone users are implemented in the upper-level device of the gateway / gateway controller device. figure 1 ...

AI Technical Summary

Problems solved by technology

Therefore, it will cause two problems: the first problem, because the circuit communication link passes through the gateway controller device twice, then two codecs must be performed during the communication, the codec is actually the compression of the voice, and the decoded The voice will be distorted, so the two codecs will cause greater voice distortion during the communication process; the second problem is that the codec process takes time, and the voice is sent from the gateway controller device to the gateway controller device through the established circuit communication link. It also takes time for the upper-level equipment to be received by the gateway controller equipment from the upper-level equipment, which increases the network delay and reduces the voice quality of the telephone user's communication

[0012] Though, this method has solved the problem that the telephone user under the jurisdiction of the same gateway / gateway controller will carry out the problem of twice codec to the transmitted voice in the communication process, but also has shortcoming: one, when gateway / gateway controller When the telephone users under the jurisdiction of the device are still the telephone users of the virtual exchange (CENTREX) group, these telephone users will have two telephone numbers of the CENTREX group and the telephone number of the communication network with different lengths at the same time, and the gateway / gateway controller device also Two different telephone numbers of the same telephone user must be configured. When determining whether the called telephone user with the number carried by the call is a telephone user under the jurisdiction of the gateway / gateway controller device according to the configured number, that is, when performing telephone number analysis It will be more difficult; two, because the call management function of the telephone user is realized in the upper-level equipment of the gateway / gateway controller device, after the upper-level device of the gateway / gateway controller device modifies the telephone number of the telephone user, it also needs to manage the phone number The phone number of the phone user is modified on the user's gateway / gateway controller device, which makes it difficult to maintain the IP network
