Abstract

The embodiment of the present invention proposes a method and system for an independently deployed 5G system to carry MBMS. The MBMS entity receives the MBMS request from the server, determines the cell that needs to broadcast MBMS and belongs to the gNB, the broadcast method of broadcasting MBMS in the cell belonging to the gNB, and the MBMS configuration information corresponding to the broadcast method; the gNB receives the MBMS configuration information from the MBMS entity, and based on the MBMS configuration The information receives MBMS data from the MBMS entity; the gNB broadcasts the MBMS data in the cell belonging to the gNB based on the broadcast method. The embodiments of the present invention implement functions such as BM-SC, MBMS-GW, MME, and MCE in the LTE system by adding a logical network element, and effectively compress the time delay of MBMS bearer establishment.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method and a system for carrying a multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS) in an independently deployed 5G system. Background technique [0002] MBMS is a typical service supported by the LTE system in the 3GPP protocol. The service can be transmitted to a specific user terminal (UE) through a unicast bearer, or broadcast in a cell through an MBMS bearer (MBMS Bearer). figure 1 It is an architecture diagram of MBMS in the LTE system in the 3GPP protocol. When the UE is in a non-roaming scenario, the PLMN is a home PLMN (H-PLMN); when the UE is in a roaming scenario, the PLMN is a visited PLMN (V-PLMN). E-UTRAN consists of a Multi-Cell Multicast Coordination Entity (MCE) and an Evolved Base Station (eNB). [0003] by figure 1 For example, the process of broadcasting MBMS with MBMS bearer is as follows: ...
