A control method for cell search compression mode of broadband code division multi-address system

Abstract

The invention discloses a control method of community search compression modes of broadband code division multiple access systems, which comprises the following steps. Firstly, compression modes are mapped into compression mode sequences of the number equivalent to the total number of gaps of the compression modes and corresponding to the gaps. Secondly, whether collision is present in the compression mode sequences is inspected; in case of collision, the step 1 shall be returned to, or else, whether compressed frames of continuous three frames or more than three frames are present after sequence combination of the compression modes is detected; if the compressed frames are present, the step 1 shall be returned to; or else, the step 3 is accessed. Thirdly, corresponding timers are provided according to the number of the compression mode number; the timers produce corresponding compression mode time sequences according to corresponding compression modes. Fourthly, operation of corresponding hardware is dispatched according to the compression mode time sequences. According to the technical proposal, central control method is adopted for the community search compression modes. The invention is characterized in that software and hardware resources of the system can be saved; and the invention is applicable for independent operations of search for and measurement of resources in communities.

Description

technical field [0001] The invention relates to the technical field of WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) communication system handover, in particular to a control method for WCDMA system cell search compressed mode. Background technique [0002] In WCDMA system FDD (Frequency Division Duplex, frequency division multiplexing) mode, in order to perform inter-frequency handover, frequency division to time division handover and inter-system handover, UE (User Equipment, user equipment) needs to measure the handover target cell , these measurements are generally different from the current operating frequency of the UE, and inter-frequency and inter-system measurements need to be performed. Since a set of transceivers can only work on one set of transceiver frequencies at the same time, if signals of other frequencies need to be measured, the receiver needs to stop working and switch to the target frequency for measurement. The...

Problems solved by technology

According to the third-generation mobile communication protocol, when the system enters the compressed mode, there will be multiple patterns at the same time. When it acts on multiple resources of cell search and measurement, it is difficult to control

If each resource for cell search independently controls the compression mode, a large amount of system resources will be consumed, that is, resources for cell search and measurement cannot be fully utilized
