Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing:

[0022] refer to figure 2 , using the method of the present invention to deal with the uplink out-of-sync process of some links during soft handover is as follows:

[0023] 1. During a call or other business, soft handover occurs due to location movement of the UE. Assume that the current active set includes multiple links, which are respectively marked as RL1, RL2, ..., RLn, and these links The uplink signals of the link are combined at the RNC.

[0024] 2. The NODEB detects that RL1 is out of synchronization in the uplink, sends a RADIO LINKFAILURE INDICATION message to the RNC, and indicates that the reason for the failure is out of synchronization in the uplink.

[0025] 3. The RNC does not delete the link after receiving the uplink out-of-sync message of RL1, but keeps it in the active set, and notifies the MDC entity that the uplink out-of-sync of RL1 is notified, a...

Abstract

This invention discloses a method for processing loss of synchronization of the up-link in the soft switch period, when loss of synchronization happens to part links in the soft switch, the RNC does not delete it but maintains it in the action set and informs the MDC entity to stop waiting and merging the up data of the branch of said link, which can keep the down soft switch gain of the link and avoid the phenomenon of adding or deleting links frequently resulted in the loss of synchronization of the up link.

Description

technical field [0001] The invention relates to a method for processing link out-of-sync in the WCDMA field, in particular to a method for processing up-link out-of-sync during soft handover. Background technique [0002] In the field of wireless communication, the air interface of the WCDMA system adopts the FDD (Frequency Division Duplex) system. A notable feature of it in mobility management is that it can use soft handover technology, that is, the UE (user terminal) can pass through multiple wireless links. The road communicates with the network. When multiple wireless links are merged in soft handover, the one with the better signal is selected through comparison, so as to achieve the purpose of optimizing the communication quality. Wherein, the uplink soft handover performs multipath combination in the RNC (Radio Network Controller), the uplink softer handover performs multipath combination in the NodeB, and the downlink soft handover performs multipath combination in...
