FIELD: information technology. ^ SUBSTANCE: method involves the following: a first network element sends a request to a second network element, the request carrying first information and identification information of data stream, and is used to acquire a radio link control (RLC) 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 receives 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. Using the present invention, synchronisation of a RLC sequence number between lower level network elements can be supported by obtaining lower level network elements which lost data or were reset, the correct RLC sequence number from other properly working lower level network elements. ^ EFFECT: preventing radio interference between neighbouring cells. ^ 19 cl, 10 dwg |
