Abstract

The invention provides a method and device for a trunking user to quit a group call. The method comprises steps of: proactively quitting a group call in progress, storing the group number and the group identifier of the quitted group call; receiving trunking paging messages and ignoring a received trunking paging message if the received trunking paging message includes the group number and the group identifier of the quitted group call; and deleting the stored group number and the stored group identifier when the calling of the quitted group call ends. The method may effectively prevent the trunking user from getting access to the group call again by mistake under the influence of a trunking system lagged enter mechanism, prevent air interface signaling information modification, extra increased air interface overhead, signaling interaction with a trunking system, and is simple and fast in quitting process, and good in practicality.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for a trunking user to withdraw from a group call. Background technique [0002] Time Division-Long Term Evolution (TD-LTE) technology is a new generation of wireless access technology for broadband mobile communication. Compared with the wireless access technology of existing 2G and 3G mobile communication systems, Small delay, high quality of service (Quality of Service, QoS) guarantee and so on. In the existing TD-LTE technology, it is the development direction of the trunking communication system to increase the characteristics of the trunking service and realize the TD-LTE broadband digital trunking communication system. The broadband digital trunking communication system based on TD-LTE technology can not only support various multimedia services of the TD-LTE mobile communication system itself, but also provide basic trunking call services and t...
