Example

[0062] The first embodiment: preset at least two conversion times and send them to the UE at the same time; and the specific method for the UE to select the conversion time and perform the conversion between the old and the new link during the conversion time is: the UE receives the link conversion message Time plus the UE’s conversion preparation delay to obtain a first reference time, and select a shortest conversion time after the first reference time from the preset conversion time as the actual conversion time. Time to switch between new and old links.

[0063] This achieves such an effect: in a scene with good signal coverage, it is easy for the UE to receive link switching messages, and it will give priority to a short switching time, and in a scene with poor signal coverage, a longer switching time will be selected. So as to achieve the purpose of shortening the connection delay.

[0064] figure 2 This is the information exchange flowchart of the first embodiment. It is ...

Example

[0101]The third embodiment: the network side presets the conversion time and sends it to the UE. The conversion time is set to be converted immediately or set to a shorter time than the existing conversion time. After the UE receives the link conversion message, it does not need to be Perform downlink synchronization on the new link, and perform the conversion between the new link and the old link according to the conversion time, that is, immediately or in a short time; after receiving the link conversion message, the UE returns to the network side through the old link. Road conversion complete message, namely RB SETUP COMPLETE or RB RECONFIGCOMPLETE. The RNC on the network side learns that the UE has received the link switch message by receiving the link switch complete message, and informs the NodeB on the network side to switch between the new and old links on the network side according to the preset switch time, that is, switch or switch immediately. Convert in a short time. ...

Example

[0120] The fourth embodiment: the network side presets the conversion offset delay and sends it to the UE; after the UE receives the link conversion message, it determines one according to the preset conversion offset delay and its own conversion preparation delay. The agreed conversion time, and the conversion between the new link and the old link is performed according to the agreed conversion time; the UE sends the agreed conversion time to the RNC through the old link; after the RNC receives the agreed conversion time, it notifies the NodeB to follow the The agreed conversion time is used to convert the old and new links on the network side.

[0121] The conversion offset delay is: the uplink delay from the UE to the network side, the processing delay of the control node on the network side, the transmission delay from the control node to the network side relay node, and the processing time of the relay node Yan Zhihe.

Abstract

Characters of the method are that in procedure for switching links, after collecting complete message of link conversion, UE selects switching time, and carries out switching between new and old links at the switching time; meanwhile, using old link sends link message of UE to network side; based on message reported from UE network side switches new and old links at network side. The invention guarantees uninterrupted link, and improves jointing time delay of switching links.

Description

technical field [0001] The invention relates to link connection conversion technology of a communication system, in particular to a link conversion method for shortening connection time delay in a communication system. Background technique [0002] Connection delay is an important problem in Wideband Code Division Multiple Access (WCDMA) systems. Too long connection delay will directly affect the subjective experience of users and affect the loyalty of users to the WCDMA operating network. The link establishment in the connection process is divided into synchronous establishment and asynchronous establishment. Synchronous establishment is during the establishment process, the radio network controller (RNC) notifies the base station (NodeB) and the user terminal (UE) to switch from the old link to the new link at a specified switching time (CFN). Asynchronous establishment means that RNC establishes links for NodeB and UE respectively, but it does not guarantee that the new ...
