Method, system and equipment for configuring wireless link control layer sequence number

Abstract

The invention provides a method, a system and a device for configuring wireless link control layer series number (RLC SN), which include the following steps: determining the type for distributing RLC S is independent RLC SN or reusing group data convergence-level series number (PDCP SN), configuring the RLC entity of the sending terminal and the RLC entity of the receiving terminal according to the determined type of RLC SN. This type of determination of RLC SN distribution mode according to QoS parameter, instead of using fixed RLC SN distribution mode, can realize flexible configuration of RLC SN distribution mode, which has sufficiently developed the advantages of independent RLC SN mode and reused PDCP SN mode.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, system and equipment for configuring serial numbers of a radio link control layer. Background technique [0002] With the continuous development of network technology, in order to meet the application requirements of mobile networks in the next ten years or even longer, the third generation partnership project (3GPP, 3 rd Generation Partnership Project) started the Long Term Evolution (LTE, Long Term Evolution) project in the second half of 2004, aiming to provide users with services of higher speed and better performance. The evolved terrestrial radio access network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) in LTE is composed of an evolved base station (eNB, E-UTRAN NodeB), and the eNB provides a user plane and a control plane to user equipment (UE, User Equipment) agreement terminated.

Problems solved by technology

In this way, since the RLC SN reuses the PDCP SN, the overhead of the RLC PDU can be saved; however, in this way, when the processing of the PDCP PDU is divided, it is necessary to add an offset to the RLC header to indicate the position of the division , usually the offset is about 11 bits, which has no obvious effect on saving the overhead of RLC PDUs, but it will increase the complexity of combining PDCP PDUs at the receiving end

[0008] Since the two ways of allocating RLC SNs in the prior art are fixedly configured in the RLC entities of the sending end and the receiving end, this makes the existing way of configuring RLC SNs unable to give full play to the advantages of the two ways of allocating RLC SNs. Very limited and less flexible
