Example Embodiment

[0052] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0053] The core idea of ​​the present invention is: after the network side notifies the base station where the user terminal of the called group is located to release the cluster context, the base station where the user terminal of the called group is located sends the group call release message by broadcasting, that is to say, the present invention is based on TD-LTE broadband digital The group call release method implemented by the trunking communication system enables the group call release message to be issued in a broadcast mode. After the user terminal of the called group receives the broadcast message, the group call release is directly performed without sending a response to the base station where the called group user terminal is located. ...

Abstract

The invention discloses a group call release method, which is realized on the basis of a time division-long term evolution (TD-LTE) broadband digital trunking communication system. The method comprises the following steps: a calling user terminal and a called group user terminal execute call release respectively; and when the called group user terminal executes the call release, a mobility management entity (MME)/service gateway (SGW) initiates a trunking context release process to a base station where the called group user terminal is located, then the base station where the called group user terminal is located transmits a group call release message to the called group user terminal in a broadcast manner, wherein the called group user terminal comprises a calling user terminal and a called user terminal, and the base station where the called group user terminal is located comprises the base station where the calling user terminal is located and the base station where the called userterminal is located. By adopting the method, quick release of group call can be realized.

Description

technical field [0001] The invention relates to TD-LTE broadband digital trunking communication system technology, in particular to a group call release method. Background technique [0002] Due to its unique characteristics of dispatching, group calling and fast calling, the digital trunking communication system has played a huge role in the field of professional communication. Since the mid-1990s, the digital trunking communication system has risen in the world, has been widely used, and has achieved good economic and social benefits. In the existing digital trunking communication technology system, Terrestrial Trunked Radio (TETRA) and Integrated Digital Enhanced Networks (Integrated Digital Enhanced Networks, iDEN) are the most widely used. Access, CDMA) technology-based open trunking architecture (Global Open Trunking Architecture, GoTa) and Global System for Mobile Communications (Global System for Mobile Communications, GSM)-based GT800 technology. [0003] The grou...
