Embodiment Construction

[0030] As shown in Figure 3, a kind of control method of wideband code division multiple access system cell search compressed mode comprises the following steps:

[0031] Step 1: according to the total number of gaps in the compression mode, the compression mode is mapped into a compression mode sequence whose number is the total number of gaps and corresponds to each gap;

[0032] Step 2: check whether there is a conflict in each compressed mode sequence, if there is a conflict, return to step 1, otherwise detect whether there are consecutive 3 or more compressed frames after the compression mode sequence is synthesized, and if so, return to step 1, Otherwise, go to step three;

[0033] Step 3: Configure corresponding timers according to the number of compressed mode sequences, and each timer generates corresponding compressed mode timings according to corresponding compressed mode sequences;

[0034] Step 4: Scheduling corresponding hardware to run according to the compress...

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...
