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 shortening the delay of group call establishment; the second and third schemes both use the standard Poc service for enhancement, and the optimization space is limited due to the limitation of the Poc service's own process
Although the third scheme uses the MBMS joint transmission scheme to optimize the air interface, it is not obvious to the optimization of the overall scheme

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 that the cluster use two systems: Terrestrial Trunked Radio (TETRA, Terrestrial Trunked Radio) and Integrated Digital Enhanced Network (iDEN, Integrated Digital Enhanced Networks). In the next few years, the open trunking architecture (GOTA, Global Open Trunking Architecture) based on Code Division Multiple Access (CDMA, CodeDivisionMultipleAccess) technology and GT800 based on GSM technology independently developed in China 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 als...
