Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0039] The LTE wireless access network based on BTrunc is a private network broadband trunking communication system, which can provide broadband trunking service functions such as multimedia trunking scheduling, and has the characteristics of flexible bandwidth, high frequency efficiency, low delay and high reliability, and can meet the needs of professional users. Voice trunking, broadband data, and emergency command and dispatch requirements. The LTE wireless access network based on BTrunc has three basic service types of "voice", "data" and "video", which can realize services such as group call / visual group call, individual call / visual individual call, and emergency call .

[0040] The embodiment of the present invention adopts the LTE wireless acce...

Abstract

The invention discloses a system and a method for realizing cluster communication by a passenger information system (PIS) service. A PIS server and a vehicle-mounted station are accessed to an LTE wireless access network based on broadband trunking communication (BTrunc). After the LTE wireless access network based on BTrunc controls the vehicle-mounted station to realize cluster grouping, the PISserver performs multicast of communication information in the cluster group through the LTE wireless access network based on BTrunc, so that the vehicle-mounted station in the cluster group is released through the visual equipment connected with the vehicle-mounted station after receiving the communication information. In this way, due to the fact that the LTE wireless access network based on BTrunc is introduced into the rail transit system, communication information transmission of the PIS service is carried out on the vehicle-mounted station in a trunking communication mode.

Description

technical field [0001] The communication system of the rail transit of the present invention particularly relates to a system and a method for realizing cluster communication of Passenger Information System (PIS) business. Background technique [0002] With the development of rail transit, technologies for realizing communication in the rail transit system have been proposed, including PIS. PIS is a multi-media system that relies on multimedia network technology and takes computer systems as the core to allow passengers to timely and accurately understand train operation information and public media information through display on-board stations installed in station halls, platforms, entrances and exits, and trains in the rail transit system. The comprehensive information system is an important facility for the subway system to realize people-oriented, improve service quality, and speed up the transmission of various information announcements. It is an effective tool to impro...
