Problems solved by technology

These three solutions have some disadvantages in the group call performance solution. Although the first solution optimizes the air interface, due to the use of the public network architecture of the TD-LTE core network, multiple interactions between the core network devices are required during the group call establishment process. , which is not conducive to shorten

Embodiment Construction

[0042] The embodiment of the present invention provides a method and device for group call release, which are used to realize group call release under a new TD-LTE broadband multimedia trunking architecture, reduce signaling interaction in the group call release process, and further reduce group call Release delay to improve group call release efficiency.

[0043] The network architecture of the TD-LTE broadband multimedia cluster provided by the embodiment of the present invention is as follows figure 1 As shown, the system includes user equipment (UE), evolved base station (eNB), trunking mobility session management entity (TMSE, Trunking Mobility Session Entity), home subscriber server (Home Subscriber Server, HSS), scheduling server (Server ), dispatching desk and operation and maintenance desk.

[0044] Under the system architecture, the core network adopts the idea of ​​centralization, and the functions of core network equipment are unified by TMSE. TMSE directly contro...

Abstract

The invention discloses a group calling release method and a device thereof for achieving group calling release under novel time division-long term evolution (TD-LTE) broadband multi-media cluster architecture, reducing signaling interaction in the process of group calling release procedure, further reducing group calling release time delay and improving group calling release efficiency. The group calling release method comprises the following steps: a session management entity topic meta-search engine (TMSE) where cluster mobility called user equipment (UE) belongs to receives group calling release requests of the called UE, and the TMSE where the called UE belongs to sends information of the group calling release requests to a dispatch server, wherein identification of the called UE is carried.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a group call release method and device. Background technique [0002] On December 28, 2000, the Ministry of Information Industry officially released the "Digital Trunked Mobile Communication System System", and recommended the use of terrestrial trunked radio (TETRA, Terrestrial Trunked Radio) and integrated digital enhanced networks (iDEN, Integrated Digital Enhanced Networks) Two systems. In the following years, the open trunking architecture (GOTA, Global Open Trunking Architecture) based on Code Division Multiple Access (CDMA, Code Division Multiple Access) technology independently developed in China and the GT800 based on GSM technology came out. [0003] With the rapid development of the mobile Internet and the popularization of TD-LTE technology, the demand for mobile communication broadband is becoming more and more obvious, and the trunking system is also...
