Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The core of the present invention is to complete the protocol interaction between the RNC and the NodeB through the wireless link asynchronous process, and then complete the reconfiguration of the physical layer parameters of the NodeB, so as to achieve the purpose of quickly and efficiently configuring the physical resources of the wireless link. The wireless link is back in sync as soon as possible.

[0020] The invention discloses a method for restoring a wireless link, which includes: when the RNC learns that the wireless link between the user terminal UE and the NodeB in the serving cell is out of synchronization, the RNC performs asynchronous reconfiguration on the NodeB in the serving cell to complete the reconfiguration of the NodeB in the serving cell resource reconfiguration of the wireless link.

[0021] The RNC can know that a wireless link is out...

Abstract

When the radio net controller (RNC) finds out lost synchronization of the comm. link between the user end (UE) and the service cell NodeB, RNC reconfigures asynchronously NodeB to complete the resource reconfiguration of the radio link. Via RADIO LINK RECONFIGURATION REQUEST MESSAGE, RNC sends reconfigured physic parameters to NodeB. After the reconfigured data become effective, NodeB sends back the RADIO LINK RECONFIGURATION RESPONSE message. Via the non-synchronization procedure of radio link, this invention completes the protocol interaction between RNC and NodeB; further completes the reconfiguration of physic layer parameters of NodeB. The aim of configuring fast and effectively the radio link physic resource is reached. The radio link losing synchronization restores rapidly to the synchronization state.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for restoring a wireless link after failure. Background technique [0002] In the current TD-SCDMA communication system, when a user (UE) communicates with a network side, there is an event that a link fails due to poor link quality, thereby causing communication transmission to be blocked. When the user detects that the downlink radio link fails, it usually performs a cell reselection process, and sends a cell update message in the selected cell. If the UE still reports the cell update caused by the failure of the radio link from the common channel of the original serving cell, it means that the signal quality of the original serving cell is good, and it is necessary to reconfigure the parameters of the NodeB (serving cell) and the UE to restore the wireless link. communication. [0003] Please refer to FIG. 1 , which is a flow chart of restoring the wireless link after the ...
