Problems solved by technology

In practice, it is not always necessary to perform three switchings, and sometimes only three switchings may not be able to fully realize the switching
[0007] In addition, the above method has a limited scope of application and is only applicable to the current WCDMA FDD system mode. For the situation where the FDD system technology can improve the HSDPA service throughput at the cell edge, the handover efficiency of the existing technology is also low
Therefore, the above method is not suitable for wireless communication systems with higher throughput of HSDPA edge services

Embodiment Construction

[0037] Since 3GPP does not support high-speed data services in R4 and previous versions, the following agreement is made for the convenience of description without causing confusion: cells are divided into cells that do not support high-speed data services and those that support high-speed data services (such as HSDPA services) Here, the cells that support high-speed data services are referred to as HSDPA cells; the cells that do not support high-speed data services are referred to as R4 cells; the channels that do not support high-speed data services or signaling are referred to as R4 version channels.

[0038]The technical scheme of the invention is applicable to a wireless communication system supporting the high-speed data packet transmission function. The main idea is to first obtain the distance between the user equipment (UE, User Equipment) and the base station according to the measured path loss, and judge whether the UE has entered the handover area at this time; Han...

Abstract

The method comprises: deciding if the performance of high speed data service can satisfy the need of coverage at the switch area; if yes, then deciding if the neighboring cell allows making the switch of high speed data service channel; if yes, then directly switching to the high speed data service channel of neighboring cell, and making traditional cell switch; otherwise, using the normal channel to make switch. The invention also reveals a switch unit comprising a decision unit used for deciding if the high speed data service can satisfy the need of coverage at the switch area; a switch processing unit used for directly switching to the high speed data service channel of neighboring cell, and making traditional cell switch; otherwise, using the normal channel to make switch or using normal channel to make switch.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for network switching of a wireless communication system. Background technique [0002] At present, most of the networking of wireless communication systems adopts high-speed data transmission technology to meet the requirements of high-speed data services of terminals, so as to obtain higher data flow and rate, and reduce the waiting time of data transmission. Typically, high-speed downlink packet access (HSDPA, High Speed ​​Downlink Package Access) or High Speed ​​Uplink Package Access (HSUPA, High Speed ​​Uplink Package Access) technology. For operators, HSDPA / HSUPA can improve the data capacity, spectrum efficiency, cost-effectiveness of WCDMA and TD-SCDMA systems, and reduce transmission costs; for ordinary terminals, HSDPA / HSUPA can provide higher data rates and shorter faster service response times and better service reliability. [0003] After adop...
