System and device for achieving cluster service

Abstract

Disclosed are a trunked service realization system and device, for reducing the signaling interaction during trunked service process, reducing trunked service time delay and improving trunked service efficiency. The trunked service realization system provided by the present application comprises a TMSE and a scheduling server; the TMSE is used to convert a trunked service request message received from a user equipment (UE) into a session initiation protocol (SIP) message, and transmit the SIP message to the scheduling server; the TMSE is further used to convert the SIP message received from the scheduling server into a message identifiable for the UE, and transmit the message to the UE; the scheduling server is used to receive the SIP message transmitted by the TMSE, conduct processing according to the SIP message, and transmit the processing result to the TMSE via the SIP message.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a system and device for realizing trunking services. 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 s...

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
