Method and device for optimizing group call context establishment

Abstract

The invention relates to a group call context establishment optimization method. The method comprises the following steps: after a group establishment success message is replied to a core network, ifgroup call context establishment failure of any cell within a first set period is detected, then initiating a group call context establishment step to the cell again within the next first set period,until the group call context establishment is successful. The invention further provides a group call context establishment optimization apparatus. After replying the group establishment success message to the core network, a base station initiates periodic group call context reestablishment to the cell subjected to group call context establishment failure, until the group call context establishment of the cell is successful. After a group call is initially established, in order to solve the problem of group call context establishment failure of a part of cells, an effective supplementary establishment method is provided, the core network does not need to participate in the reestablishment process, thus effectively reducing signaling interaction, accordingly, the coverage capability of thegroup call service is improved, and the performance and reliability of the entire communication system are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a group call context establishment optimization method and device. Background technique [0002] With the continuous development of information and communication technology, communication systems are constantly being upgraded to meet people's ever-increasing production technology needs and quality of life needs. In the contemporary communication system, the trunking system is a representative communication application system. The trunking system is developed to meet the requirements of industry command and dispatch, and has a wide range of applications in the fields of public safety, transportation, public utilities, petrochemicals, industry, commerce, and military. During the continuous development of mobile communication, the trunking system has gradually developed from the initial 2G narrowband wireless communication system to a broadband trunking system. While...

AI Technical Summary

Problems solved by technology

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the traditional technology: In the traditional trunking system, for the establishment of a group call, the main concern is the time delay of the group call context establishment process, and the context establishment on the terminal. process optimization and other issues

However, when multiple base stations support multiple cells, etc., the reliability of the system is still not high.
