Digital cluster system and method of managing mobility for users

Abstract

The invention is used in a digital trunking system comprising user end, access network and core network with packet domain and scheduling domain. The method comprise: 1) the packet domain synchronizesthe mobility management data of managing the user end of digital trunking system to the scheduling domain; 2) scheduling domain receives the mobility management data and makes management for the userend of digital trunking system.

Description

technical field [0001] The present invention relates to a digital trunking system, in particular to a system and method for managing user mobility in a TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access) digital trunking system. Background technique [0002] The trunking communication system was born in the 1970s. The earliest trunking communication was an analog system. The digital trunking technology began to rise around the world in the mid-1990s, and a digital trunking network appeared in China in the late 1990s. Digital trunking technology has the advantages of fast connection, high spectrum utilization, and flexible networking. It is mainly used in special mobile communication systems for production scheduling, command and control, and plays an extremely important role in improving production and work efficiency and ensuring safety. [0003] The traditional digital trunking system is mostly used in private networks. The problems of private networks are: (...

AI Technical Summary

Problems solved by technology

[0003] The traditional digital trunking system is mostly used in private networks. The problems of private networks are: (1) The construction of a separate network is repeated with the construction of the public network, resulting in waste of resources; (2) Difficult maintenance, a large number of small-scale private networks require a large Specialized technicians are required for maintenance; (3) It is difficult to upgrade technology; (4) The service scope and service population are limited

[0013] However, because scheduling exists as an independent domain in the TD-SCDMA digital trunking system, the scheduling domain needs to complete all the processes of mobility management by itself

Many of these mobility management processes are repeated with the mobility management processes in the circuit domain and packet domain, which makes the mobility management function in the core network scheduling domain relatively complicated; After the mobility management process in the scheduling domain and packet domain, it needs to be repeated in the scheduling domain. On the one hand, it causes a waste of air resources, on the other hand, it also increases power consumption, and shortens the standby time of terminals.
