Abstract

The invention discloses a subway PIS service multicast method and device based on LTE broadband trunking communication. The method comprises the following steps: configuring a PIS trunking group by atrunking core network, and setting a multicast IP; initiating group calling by the trunking core network; sending a PIS service message provided with the multicast IP to the trunking core network by aPIS server; multicasting a GTP-U message comprising the PIS service message and the multicast IP to an eNB by the trunking core network; sending a PDCP message containing payload data to a terminal by the eNB; receiving the PDCP message by the terminal and analyzing, and if the multicast IP contains an address of the terminal, playing a PIS service. The invention also provides a device applicableto the method. Compared with the traditional subway PIS service multicast method and device, the method and device which are disclosed by the invention have the beneficial effects of high system capacity, high frequency utilization rate and low manufacturing cost.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a subway PIS service multicast method and device based on LTE broadband trunking communication. Background technique [0002] Passenger Information System (PIS) is a service system that provides passengers with various information in the subway. The passenger information system relies on multimedia network technology, takes the computer system as the core, and provides information services to passengers with the station display terminal and vehicle display terminal as the medium. [0003] The LTE broadband trunking communication system is a system that can provide mobile dispatching services to professional or public users, and represents the development direction of private mobile communication networks. The system has the advantages of large system capacity, high frequency utilization rate, and various functions, and has become the mainstream technol...
