Abstract: A data transmission method and apparatus, a system, and a storage medium are provided. In the method, a user plane function network element performs transmission through an established unicast user plane connection, and when sending data of a first service to an access network device, the user plane function network element can be configured to send only the data that is of the first service and that is carried in one data flow to improve use efficiency of resources on a core network side. Then, the access network device can send, in a multicast manner through an established unicast channel, the received data of the first service to a group of terminals corresponding to the data of the first service, and does not need to additionally establish a multicast channel and switch to the multicast channel, thereby further reducing data transmission delay.

Abstract: The present disclosure relates to communication methods and apparatus. One example method includes receiving, by a target service entity, a first request message from a first participating service entity, and sending, by the target service entity, a first response message to the first participating service entity. The first request message comprises an identity of a target multicast bearer and a group identity of a terminal group. The first response message is used to instruct the first participating service entity to use the target multicast bearer to send service data of the terminal group.

Abstract: Embodiments of the present application relate to the communications field, and provide a bearer establishment method and apparatus, and a system. The method includes: sending, by an eNB, a first request message to an MME in a handover process of UE; determining, by the MME, a target SGW and a target PGW of the UE based on the first request message; requesting, by the MME, the target SGW to establish a first bearer between the target SGW and the target PGW for the UE; and after the first bearer is established, requesting, by the MME, a source eNB to release a radio bearer and delete a second bearer on the source side. In the present application, a process of establishing the first bearer and the cell handover process are completed in parallel, so that the terminal can perform communication through the first bearer after a cell handover.
