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

Embodiment Construction

[0025] The embodiment of the present invention provides a method for establishing a group call, which is used to reduce signaling interaction in the process of establishing a group call, thereby reducing the time delay of establishing a group call, and improving the efficiency of establishing a group call.

[0026] 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), trunk mobility session management entity (TMSE, TrunkingMobilitySessionEntity), home subscriber server (HomeSubscriberServer, HSS), scheduling server (Server), scheduling console and Operation and maintenance of several parts of the station.

[0027] 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 controls all TD-LTE base station equi...

Abstract

The invention discloses a group calling establishing method which is used for reducing signal interaction in a group calling establishing process, and therefore reducing time delay in establishing group calling and improving the efficiency in establishing the grouping calling. The group calling establishing method includes the following steps that a TMSE receives the request for establishing group calling from calling UE; the TMSE converts the request for establishing the group calling into an SIP Invite message, wherein an instruction for establishing the group calling is contained in the SIP Invite message. The TMSE sends the SIP Invite message to a dispatching server.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for establishing a group call. 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 also develop...
