Method, base station, and broadcast multicast service center for creating, updating, and releasing synchronization entities

摘要

The present invention provides processes of creating, updating, and releasing SYNC entities between eNB and BM-SC, and an eNB and a BM-SC for implementing the processes of creating, updating, and releasing the SYNC entities. According to a solution of the present invention, a method of creating SYNC entities is provided, including: creating, at a BM-SC, a plurality of SYNC entities whose amount is equal to the total amount of services, and associating the created plurality of SYNC entities with the services in a one-to-one correspondence manner; sending a SYNC entity creating instruction to all eNBs within an MBSFN area; creating, at each eNB, a plurality of SYNC entities whose amount is equal to the total amount of services based on the received SYNC entity creating instruction, and associating the created plurality of SYNC entities with the services in a one-to-one correspondence manner.

1. A method of operating a Broadcast Multicast Service Center (BM-SC), the method comprising:
creating, at the BM-SC, a plurality of synchronization entities whose amount is equal to a total amount of services; associating the synchronization entities with the services in a one-to-one correspondence manner; transmitting synchronization entity creating instructions or synchronization entity updating instructions to all base stations within a Multicast Single Frequency Network (MBSFN) area.
