Group call channel resource managing method in mobile communication system

Abstract

Said invention provides a group calling channel resource managing method in mobile communication system. It contains base station subsystem defining down detecting message to cell down user terminal and proceeding detecting, and proceeding channel resource manager according to down user detecting result. Said invention fully considers protocol compatibility and has simple implementation method, ensuring releasing group calling channel accuracy, thereby realizing saving system resources enhancing system resources utilization.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for managing group call channel resources in a mobile communication system. Background technique [0002] According to the different characteristics of mobile user groups, mobile communication can be divided into public mobile communication and private mobile communication. Dedicated mobile communication is mainly used internally by various professional departments. The dedicated mobile communication of each professional department has its own different frequency points, different business and network requirements. [0003] Since the 1990s, with the development of digital public mobile communications, digital private mobile communications are gradually attracting people's attention. [0004] In 1993, the European UIC (European Railway Union) decided to use GSM (Global System for Mobile Communications) as the basic platform for future railway mobile communic...

Problems solved by technology

[0017] This type of user terminal is making a VGCS call, and when the base station subsystem uses the delay assignment function to manage channel resources, it will cause each cell that the user terminal passes through to reserve a group call channel, even if some cells do not have The user terminal is using the group call channel

[0018] To sum up, in the existing group call channel resource management method, when the base station subsystem adopts the delayed assignment function to manage group call channel resources, if a certain cell has allocated group call channel resources through a notification response, the After all monitored user terminals leave the cell, the group call channel resources allocated for the cell are still reserved and cannot be released automatically, which wastes system resources and makes the utilization rate of system resources low
