Problems solved by technology

[0004] The purpose of the present invention is to overcome the serious conflicts between the services existing in the existing cluster system and the CDMA system, as well as the inflexible configuration in the non-cluster CDMA network, and the shortcomings of long duration of new services, in order to propose a method that can take into account various services. A fast, flexible and diverse method to achieve business priority in the CDMA trunking system while switching between

Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0031] figure 1 Describes the network structure diagram of the shared network cluster that realizes the business priority function.

[0032] It can be seen from the figure that the entire network is composed of a cluster dispatch server, a dispatch client (PDC, PTT Dispatch Client), a base station system, and a mobile switching center. The base station system is connected to the mobile switching center through the standard A1 interface, which is mainly used to carry signaling; it is connected with the dispatching client through the A8d / A9d interface, and the A8d carries the service and the A9d carries the signaling. The scheduling client is connected to the cluster scheduling server through A10d / A11d, A10d carries services, and A11d carries signaling. The PDS is interconnected with the PDS through the PP interface, and switching and roaming can be r...

Abstract

The method includes following steps: 1) the user state is set in calling process; 2) when group call begins, the group call dispatch sever determines traffic priority; when the dispatching sever determines it is a traffic priority call, it will be instructed to base station system in paging message, it will be indicated in point segment to forcedly release priority; 3) the base station decide if it is user's ordinary call, then first makes forced releasing, then makes paging, if the user is in idle, then directly makes paging.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for realizing service priority in a cluster system based on CDMA (Code Division Multiple Access, code division multiple access) system. Background technique [0002] With the increasingly widespread application of mobile communication systems in various fields such as economy and social life, mobile communication system technology itself is also developing rapidly, from the second-generation mobile communication system that is currently widely used to the mature and perfect third-generation mobile communication system. The development of technology is increasingly meeting the needs of users for communication systems. More and more effectively meet the needs of value-added services including video, audio, and real-time multimedia service interaction, so that mobile communication systems play an increasingly important role in people's lives and work. Among them, the tr...
