Method of realizing user calling signalling tracking in PHS communication system

Abstract

When user calls, mobile terminal sends authentication request to register of access location. Flag bit to show whether the user carries out signaling tracking is added to the message responded by the register of access location. Hereafter, the signaling tracking symbol is transferred to relevant signaling message along with calling flow. When the calling signaling flows through a module, the module determines whether the signaling tracking symbol is true. If yes, the corresponding signaling message and message body are reported to operational maintenance terminal. The invention makes personnel for operating and maintaining mobile communication system obtain internal signaling flow and contents of the mobile users easily. Thus, faults in system can be solved in shortest time so as to reduce loss of users and managers.

Description

(1) Technical field [0001] The invention relates to a method for tracking user call signaling in a PHS communication system, which is an efficient and real-time tracking method for mobile user call signaling in the PHS communication system. By using this method, the detailed flow and content of PHS mobile user call signaling can be completely displayed on the terminal, so as to realize the tracking of user calls, facilitate the analysis and location of call faults in the system, and have minimal impact on the system load. (2) Background technology [0002] At present, mobile communication technology has been used on a large scale and penetrated into all walks of life and people's lives. The mobile communication system is a communication system that can establish many information transmission channels between mobile objects, between mobile objects and fixed-point users, and between fixed-point users and mobile objects. Mobile communication includes wireless transmission, wir...

Problems solved by technology

This method is not suitable for mobile communication systems, because: 1. Mobile communication systems are different from wired systems, and the location of users is not fixed. When users roam, signaling will flow through many scattered devices. To track it down completely, it is necessary to use the broadcast method to issue a signaling tracking command for a user call to all devices, which will add a lot of unnecessary processing to the program, and if there is a problem with the transmission, some modules will lose the signal. If the tracking flag is set, the reported signaling is incomplete and the purpose of tracking cannot be achieved; 2. In the mobile system, different devices and modules have inconsistent representations for users. For example, in some parts, users are uniquely identified by phone numbers, and in some parts , is uniquely identified by the protocol address, and some parts are uniquely identified by the mobile phone ID. If tracking of a certain user is set in each module, many user ID conversions are required. At the same time, the comparison operation of long strings will seriously affect system efficiency

3. The signaling trace flag records need to be sent and recorded in each module, and the stability is poor. When the signaling trace flag in a module is lost, it is easy to cause incomplete signaling reporting
