Patent ID: 8160052

Claim:
A method for synchronizing stream records between devices of a bearer control layer and a bearer layer, comprising: returning, by a bearer layer device, a stream record corresponding to a stream synchronization request sent from a resource manager (RM), to the RM on the bearer control layer in response to the stream synchronization request sent from the RM; and comparing, by the RM, a stream record stored in the RM with the stream record returned from the bearer layer device; and performing, by the RM, a stream synchronization process on to-be-synchronized information in the bearer layer device in accordance with a comparison result; wherein the process of performing the stream synchronization process by the RM comprises: receiving, by the RM, the stream record corresponding to the stream synchronization request sent from the RM, returned from the bearer layer device, searching stream records stored in the RM for the stream record returned from the bearer layer device, and if the stream record returned from the bearer layer device is absent in the stream records stored in the RM, instructing the bearer layer device to delete the stream record absent in the stream records stored in the RM and returned from the bearer layer device; if the stream record returned from the bearer layer device is present in the stream records stored in the RM, comparing the stream record stored in the RM with the stream record returned from the bearer layer device, and if the stream record stored in the RM and the stream record returned from the bearer layer device are inconsistent, sending the inconsistent stream record stored in the RM to the bearer layer device and instructing the bearer layer device to update the inconsistent stream record stored in the bearer layer device.
