Abstract

The invention relates to a communication entity (100a) associated with a base station (101a). The communication entity (100a) includes: an analyzer (103) configured to analyze the content and / or type of messages received by the base station (101a); a local message distributor (105) configured to The content and / or type of the message, using a local message distribution strategy, for distributing the message to at least one user equipment in a plurality of user equipments (110a, b); and a global message distributor (107), which is configured Based on the content and / or type of the message, adopting a global message distribution strategy for distributing the message to at least one of a plurality of other communication entities (100b-d), wherein each other communication entity (100b-d ) are associated with corresponding other base stations (101b-d).

Description

Technical field [0001] Generally, the present invention relates to wireless communication. More specifically, the present invention relates to a communication entity associated with a base station and a method of operating such a communication entity. Background technique [0002] In the existing LTE architecture, the evolved multimedia broadcast multicast service (eMBMS) architecture is designed to support multicast / broadcast applications, such as IPTV, broadcast file delivery, live audio / video streaming, and so on. It is not designed for intelligent transportation system (ITS) scenarios that require low latency and high reliability (that is, the safety and efficiency of the transportation system). In the existing LTE architecture, the service is sent to the BM-SC by the operator (for example, a TV operator), and then it is delivered to the MBMS-GW, which performs a multicast operation on the received service. Generally, the MBMS-GW is located in the core network far from the ...
