Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcoming of being unable to realize cross-cluster scheduling server hard handover in the existing CDMA system cluster system, in order to realize the hard handover function in the cluster system, including cross-base station hard handover and cross-scheduling server hard handover, in realizing At the same time of handover, fully take into account handover reliability, handover success rate, handover delay and other indicators, while taking into account the needs of billing

Embodiment Construction

[0026] The implementation of the technical solution in the actual system is further described in detail below in conjunction with the accompanying drawings:

[0027] Fig. 1 is a flow chart of the processing of the source base station's pilot measurement report to the mobile station. Specifically include the following steps:

[0028] 101. The base station system receives the pilot strength reported by the mobile station, and the system judges whether handover is required according to the mobile station, and initially judges the handover type;

[0029] 102. The system further judges the system resources, and judges whether the resource conditions required for trunking call switching are met;

[0030] 103. If it is determined that the handover is possible and the cell to be handed over is not located in the current BSC, then determine whether there is an interconnection relationship between the two BSCs to finally determine the handover type. When there is an interconnection re...

Abstract

The method includes following step: 1) the base station processes request for switching from mobile station; 2) the base station at target side and trunking dispatching server process the request for switching; 3) after switching is succeeded, the base station at resource side and trunking dispatching server release the resource. The invention can implement hardware switching in trunking system that includes crossing- base station hardware switching and crossing-dispatching server hardware switching.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to PDC (PTTDispatch Client, scheduling client) / BSC (Base Station Controller, base station controller) in the field of common network digital trunking based on CDMA (Code Division Multiple Access, code division multiple access) system and a method for implementing hard switching across PDS (PTT Dispatch Server, scheduling server). 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 servic...
