Abstract

The embodiment of the invention provides an MBMS (Multimedia Broadcast Multicast Service) transmission method and equipment, and the method is applied to a DU (Distributed Unit), and comprises the steps: receiving a first notification message transmitted by a CU (Central Control Unit); sending a first message to the CU; sending an MBMS notification message to the UE according to the first notification message, the MBMS notification message being used for notifying the UE to receive a message sent on an MBMS control channel; receiving an MBMS service starting request message sent by the CU; andsending an MBMS message to the UE, wherein the MBMS message is used for establishing an MBMS bearer and transmitting MBMS data. According to the method provided by the invention, the MBMS bearer is successfully established under a separated architecture, and the MBMS data is effectively transmitted.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular, the present application relates to a multimedia broadcast multicast service MBMS transmission method and equipment. Background technique [0002] Modern mobile communication tends to provide users with high-speed multimedia services, such as figure 1 As shown, it is a system architecture diagram of a radio access network (hereinafter referred to as NG-RAN) under 5G (Fifth-Generation, fifth-generation mobile communication technology). in: [0003] NG-RAN includes a group of base stations gNB (or enhanced eNB), connected to the 5G core network 5GC through the NG interface. The base station can support FDD (frequency division) mode and TDD (time division) mode. The gNBs can be connected through the Xn interface. A base station gNB may include a central control node (hereinafter referred to as CU) and one or more distribution nodes (hereinafter referred to ...
