摘要
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present disclosure provides a method for establish a channel, a base station, and a multi-cell multicast coordination entity (MCE), the method being applied in the base station and including: a point-to-point establishment request transmitted by a multi-cell multicast coordination entity (MCE) is received, the point-to-point establishment request being used to indicate establishment of a point-to-point channel for transmission of a multimedia broadcast multicast service MBMS, and the point-to-point establishment request including at least one of an MBMS service identifier and an identifier of a protocol data unit session (PDU session), and a bearer establishment request is transmitted to a core network in accordance with the point-to-point establishment request, for determining that the point-to-point channel is successfully established and converting the point-to-multipoint channel to a point-to-point channel. The method provided by the present disclosure implements establishment of the point-to-point channel to a point-to-multipoint channel. The embodiments of the present application provide a multimedia broadcast and multicast service (MBMS) transmission method and device. The method is applied to a DU, comprising: receiving a first notification message transmitted by a CU; transmitting a first message to the CU; transmitting the MBMS notification message to the UE according to the first notification message, wherein the MBMS notification message is used to notify the UE to receive a message transmitted on a MBMS control channel; receiving an MBMS service start request message transmitted by the CU; transmitting a MBMS message to the UE, used for establishing an MBMS bearer and transmitting MBMS data. The method provided in the present application realizes the successful establishment of a MBMS bearer and the effective transmission of MBMS data under a separated architecture.
