Method for base station to report UE (user experience) capability, base station and system

Abstract

The invention discloses a method for a base station to report UE (user experience) capability, a base station and a system. The system comprises the base station, a UE and a core network; the base station comprises a UE capability obtaining module and a UE capability reporting module, wherein the UE capability obtaining module is used for sending initial UE message to the core network during the UE access process after receiving RRC (radio resource control) connection building completion message, and simultaneously obtaining UE capability from the UE; and the UE capability reporting module is used for reporting UE capability to the core network after receiving initial context building request message of the core network. The method, the base station and the system do not wait initial context building request message after eNB (effective noise bandwidth) sends initial UE message, directly initiate a UE capability obtaining process, can more rapidly reply UE capability message to the core network after receiving initial context building request message, and continuously access a flow, so as to ensure that the UE capability obtaining process is advanced, and the UE capability obtaining process and the initial UE message processing process are processed simultaneously, and save access time delay.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, a base station and a system for reporting UE capabilities by a base station during UE access. Background technique [0002] The 3GPP Evolved Packet System (EPS for short) is composed of an Evolved UMTS Terrestrial Radio Access Network (EUTRAN for short) and an EPS core network (Evolved Packet Core, EPC for short). [0003] Wherein, in the evolved UTRAN, the base station device is an evolved base station (evolved Node-B, eNB for short), which is mainly responsible for wireless communication, wireless communication management and mobility context management. [0004] Such as figure 1 As shown, during the UE access process, the base station reports the UE capability to the core network as follows: [0005] S101: The UE sends an RRC connection establishment request (RRC Connection Request) message to the eNB, wherein the RRC connection establishment request message carri...

AI Technical Summary

Problems solved by technology

[0016] It can be seen from the above existing process that the base station reports the UE capability to the core network, the eNB obtains the UE capability after the eNB receives the initial context establishment request message, only when the initial context establishment request message does not carry the UE capability. UE capability, which virtually turns a parallel process into a serial process, affecting UE access delay
