<p>A method and apparatus for recovering synchronization among transmitted service data are disclosed in the present invention. The method comprises: a first network element sending a request to a second network element, the request carrying first information and identification information of data stream, wherein, the request is used to acquire a Radio Link Control sequence number of a Radio Link Control protocol data unit corresponding to the data packet indicated by the first information in the data stream; the first network element receiving second information returned by the second network element according to the request and allocating the Radio Link control sequence number carried in the second information to the Radio Link Control protocol data unit in the first network element. With the present invention, the RLC sequence number synchronization among the lower layer network elements can be maintained by acquiring by the lower layer network elements which have lost data or which have restarted the right Radio Link Control (RLC) sequence number from other lower layer network elements which work properly, thus avoid radio interference among the adjacent cells.</p> |
