Call tracking method, system and device

Abstract

The method can make the media gateway to trace users' calling based on users' numbers. In the invention, the soft switch equipment adds the users' number of the calling into the call signaling sent to the media gateway; the media gateway records the corresponding relation between the users' number and the end point of the call; when receiving the tracing instruction, the media gateway finds the corresponding end point from the corresponding relation of users' number, and traces the end point; when outputting the tracing result, according to the end point ID in the tracing result the media gateway find the corresponding users' number and outputs the users' number and the tracing result together.

Description

technical field [0001] The invention relates to the communication field, in particular to a call tracking technology. Background technique [0002] Traditional communication networks used to transmit voice are usually based on Time Division Multiplexing (Time Division Multiplexing, referred to as "TDM") public switched telephone network (Public Switched Telephone Network, referred to as "PSTN"), the communication network is based on circuit switching Mainly, the business and control related to voice are completed by the switch. In a traditional TDM-based circuit switching network, the structure of the switch is shown in Figure 1. Among them, in call control, the Signaling System 7 (Signaling System 7, "SS7" for short) is widely used. [0003] With the rapid growth of data services, the traditional network based on circuit switching has brought a lot of inconvenience to data users, such as high communication prices, slow Internet speed, long waiting time, low transmission q...

AI Technical Summary

Problems solved by technology

[0014] 1. The tracking process must be initiated by the softswitch device or the network management tracking server, and the media gateway cannot track according to the user number by itself (there is no endpoint ID corresponding to the user number);

[0015] 2. There is no relevant information about the user number in the records saved and output on the media gateway, so the search and tracking results based on the user number can only be performed on the softswitch device or the network management tracking server;
