Synchronization method and system of control sequence numbers

摘要

A synchronization method and system of control sequence numbers is provide to achieve radio link control sequence number synchronization between different network elements. This method includes the following steps: allocating a preset radio link control sequence number to a first radio link control protocol data unit corresponding to a first packet in a data burst and successively allocating a radio link control sequence number to subsequent radio link control protocol data units corresponding to packets of this data burst, when each designated network element in a plurality of designated network elements performing radio link control protocol process on the packets in the data burst received by said each designated network element.

1. A synchronization method of control sequence numbers for achieving radio link control sequence number synchronization between different network elements, comprising:
allocating a preset radio link control sequence number to a first radio link control protocol data unit corresponding to a first packet in a data burst and allocating a radio link control sequence number to subsequent radio link control protocol data units corresponding to packets of the data burst by each designated network element in a plurality of designated network elements, when the each designated network element in the plurality of the designated network elements performing radio link control protocol process on the packets in the data burst received by said each designated network element in the plurality of the designated network elements; wherein the plurality of the designated network elements comprise a network element which restarts and maintains the radio link control sequence number synchronization with other designated network elements in the plurality of designated network elements which do not restart.
