Abstract

The present application discloses a subway PIS service multicast method and device based on LTE broadband cluster communication. The method includes the following steps: the cluster core network configures a PIS cluster group, and sets the multicast IP; the cluster core network initiates a group call; the PIS server Send the PIS service message with multicast IP to the cluster core network; the cluster core network multicasts the GTP-U message including the PIS service message and multicast IP to the eNB; the eNB sends the PDCP message containing the payload data Send it to the terminal; the terminal receives the PDCP message and parses it, and if the multicast IP in it contains the address of the terminal, it plays the PIS service. The present application also provides a device suitable for the above method. Compared with the traditional subway PIS service multicast method and device, the application has the beneficial effects of large system capacity, high frequency utilization rate and low 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...
