Method for trimming traffic in an e-MBMS system and BM-SC implementing the method

摘要

The present invention provides a method of trimming traffic in an e-MBMS system and BM-SC for implementing the method. The method comprises: determining, by a BM-SC, an ABBR of the multiplexing; allocating, by an MCE, resources based on the determined ABBR; determining, by the BM-SC, whether data amount to be transmitted in a synchronization period exceeds resources allocated in the synchronization period; and dropping, by the BM-SC, tail data packets that cannot be sent in the synchronization period in the multiplexed service if it is determined to exceed. Further, the method also comprises: before the step of determining, voluntarily dropping, by the BM-SC, some data packets in the multiplexed service.
