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

Abstract

The invention discloses a method for detecting that a telephone user is in the same gateway / gateway controller device. The circuit communication link between the calling telephone user and the called telephone user is established through the equipment for managing the call function of the telephone user. The method also includes : A, the gateway / gateway controller device to which the calling phone user belongs monitors the detection information sent by the gateway / gateway controller device to which the called phone user belongs on the circuit communication link; B, the gateway / gateway controller device to which the calling phone user belongs The gateway controller device judges whether the gateway / gateway controller device to which the calling phone user belongs and the gateway / gateway controller device to which the called phone user belongs are the same device according to the detection information, and if so, determines whether the calling phone user and the called phone user The users belong to the same gateway / gateway controller device; otherwise, it is determined that the calling phone user and the called phone user belong to different gateway / gateway controller devices.

Description

Technical field [0001] The present invention relates to a technology for detecting telephone users in an Internet Protocol (IP) network, and particularly relates to a method for detecting telephone users in the same gateway / gateway controller device. Background technique [0002] With the rapid development of IP networks, it has become possible to provide cheap and high-quality voice and data services on IP networks. Therefore, IP networks have increasingly attracted the attention of telecommunication equipment manufacturers and operators. Telecommunication equipment manufacturers have also introduced a variety of gateway / gateway controller devices 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 equipment, but the management functions of these telephone users are implemented in the upper-level equipment of the gateway / gateway contro...

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
