Embodiment Construction

[0053] The technical solution of the present invention will be further elaborated below in conjunction with the drawings and specific embodiments.

[0054] The embodiment of the present invention provides a digital trunking communication system based on LTE, such as figure 2 As shown, it mainly includes: terminal, E-UTRAN, and cluster scheduling subsystem. The terminal includes user equipment (UE), fixed station, vehicle-mounted station, wireless dispatching station, etc.; E-UTRAN includes eNodeB; the cluster dispatching subsystem includes dispatching server (PDS, PTT Dispatching Server), home register (PHR, PTT Home Register), Dispatching Agent Server (DAS, Dispatching Agent Server) and Dispatching Agent Client (DAC, Dispatching Agent Client). Among them, PDS is divided into control plane PDS (C-PDS) and media plane PDS (M-PDS).

[0055] The terminal and eNodeB are connected through LTE-Uu interface; eNodeB and C-PDS are connected through T1-C interface; eNodeB and M-PDS are con...

Abstract

The invention discloses a digital trunked communication system based location updating method and system. The method includes that a PDS (PTT dispatching server) receives a trunked starting-up location registration request message, location updating request message or trunked shutdown location registration request message reported by a trucking terminal through an evolved base station (eNodeB), the received request message is sent to a PHR (PTT home register), and the PHR records terminal location information carried in the request message; the PDS receives a trunked starting-up location registration response message, location updating response information or trunked shutdown location registration response message returned by the PHR, and the response message is sent to the trunking terminal through the eNodeB. By the method and system, terminal location updating in an LTE (long term evolution) based digital trunked communication system is realized.

Description

Technical field [0001] The present invention relates to the technical field of cluster communication, in particular to a location update method and system based on a digital cluster communication system. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the command and dispatching needs of industry users; in the trunking communication system, a large number of wireless users share a small number of wireless channels, with command and dispatch as the main application; the trunking communication system is one A multi-purpose, high-performance wireless communication system. [0003] The trunking communication system has experienced a similar development process to that of the cellular mobile communication system: [0004] The first generation trunking system is an analog trunking communication system, which mainly supports voice communication; [0005] The second-generation tr...
