Problems solved by technology

At present, in the CELL_FACH enhanced state, there is no effective time point information setting on the Iub interface, which may cause the UE and the base station to be unable to synchronize and use the same capability level information, resulting in the failure of normal transmission of E-DCH and HS-DSCH data

Embodiment Construction

[0023] The present invention proposes a system for enabling a base station to acquire UE context, including an RNC and a base station, the RNC is used to generate UE context information, and the UE context information includes UE HS-DSCH capability level and E-DCH capability level information, And the H-RNTI and E-RNTI of the UE, and the activation time point information used to indicate that the UE context information takes effect; the RNC sends the UE context information to the base station through the HS-DSCH data frame or control frame of the Iub interface between the RNC and the base station ; The base station is configured to receive the UE context information, and activate the UE context information at a time specified by the activation time point information.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

Abstract

The invention discloses a method for a base station to obtain user equipment (UE) context information. The UE context information comprises UE high-speed downlink shared channel (HS-DSCH) competence scale information, strengthened dedicated channel (E-DCH) competence scale information, the HS-DSCH wireless network temporary identity of UE and an E-DCH wireless network temporary identity (E-RNTI);RNC sends the UE context information to the base station through the HS-DSCH data frame or control frame of the Iub interface of the RNC and the base station; and the base station receives and saves the UE context information. The invention discloses a system causing the base station to obtain the UE context information. The scheme of the invention solves the problem that a terminal is transferred to CELL-PCH or CELL-FACH state in the HSPA+ system, the base station can not obtain H-RNTI and E-RNTI correspondence, the HS-DSCH competence scale information and the E-DCH competence scale information of the terminal to cause subsequent abnormal communication.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a system for enabling a base station to acquire UE context information. Background technique [0002] In the High Speed ​​Downlink Package Access (HSDPA) system, different user equipment (UE) capability levels are defined to support different HSDPA peak rates, and the HSDPA capability level is expressed as a high-speed downlink shared channel (High-Speed ​​Downlink Shared Channel, HS-DSCH) physical layer capability level (HS-DSCH physical layer category). In a traditional HSDPA system, the HS-DSCH physical layer capability level ranges from 1-15. [0003] The UE capability level reflects the following: [0004] UE cache size and the amount of physical channel resources that the UE can receive simultaneously within a 5ms Transmission Time Interval (TTI), the physical channel resources include time slots and code channels, etc.; [0005] The upper limit...
