Abstract:
The present disclosure discloses a data transmission method for an edge MBMS service and a related device. The method includes providing an MBMS service data transmission system that includes a central BM-SC located on a core network and an edge BM-SC and an MBMS GW that are located on a network edge; creating, by the central BM-SC, a control-plane bearer context; sending a session start request to the edge BM-SC, so that the edge BM-SC creates a user-plane bearer context; receiving a session start response sent by the edge BM-SC; and delivering a service key to the edge BM-SC, so that the edge BM-SC encrypts data of the edge MBMS service by using the service key and sends data to UE via the MBMS GW.

Claim (Index 3):
A data transmission method for an edge multimedia broadcast/multicast service (MBMS) service, wherein the method is applied to a system comprising a central broadcast/multicast service center (BM-SC) and an MBMS gateway (GW) control-plane functional entity that are located on a core network and an edge BM-SC and an MBMS GW user-plane functional entity that are located on a network edge, the MBMS GW user-plane functional entity is corresponding to the MBMS GW control-plane functional entity, and the method comprises:\n receiving, by the edge BM-SC, a session start request from the central BM-SC, wherein the session start request comprises a temporary mobile group identity (TMGI) of the edge MBMS service; creating, by the edge BM-SC, a user-plane bearer context for the edge MBMS service in responsive to the session start request; sending, by the edge BM-SC, the session start request to the MBMS GW control-plane functional entity, wherein the session start request is used for requesting allocation of an Internet Protocol (IP) multicast address and creation of a control-plane bearer context for the edge MBMS service; receiving, by the edge BM-SC, a session start response from the MBMS GW control-plane functional entity, wherein the session start response comprises the TMGI; sending, by the edge BM-SC, the session start response to the central BM-SC; receiving, by the edge BM-SC, a service key delivered by the central BM-SC; and encrypting, by the edge BM-SC, data of the edge MBMS service by using the service key, and sending encrypted data of the edge MBMS service to a user equipment (UE) via the MBMS GW user-plane functional entity.
