Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings.

[0035] As shown in Figure 1, the cell search method in the mobile system according to the present invention includes step S102, applying for time slot synchronization resources, configuring related parameters, when the time slot synchronization running time is up, generating a time slot synchronization result, and performing the time slot synchronization Peaks are sorted, multiple peaks and peak position offsets are taken out, and time slot synchronization resources are released at the same time.

[0036] In addition, step S104 is also included, applying for one of the two frame synchronization and scrambling code group identification resources according to predetermined rules, setting relevant parameters according to the result of step S102, and searching for multiple peaks and peak position offsets of time slot synchronization respectively , the result of the search is the f...

Abstract

The present invention provides a community search system in broadband code division multiple access mobile communication, which comprises a time slot synchronizer to configure relevant parameters, create time slot synchronization upon operation expiration of time slot synchronization, rank peak values of time slot synchronization, take out a plurality of peak values and peak value deviations and synchronously release time slot synchronization resources and two frame synchronization and scrambled code set recognizer to configure relevant parameters according to result of the time slot synchronizer, respectively search a plurality of peak values and peak value deviations of the time slot synchronization. Search results are frame synchronization time point and scrambled code set. After the search, corresponding resources are released. Therefore, the present invention is capable of fulfilling concurrent operation of time slot synchronization, frame synchronization, scrambled code set recognition and scrambled code recognition, thus improving search efficiency.

Description

technical field [0001] The present invention relates to a cell search system in the field of wireless communication, more specifically, to a cell search system in a WCDMA (Wideband Code Division Multiple Access) mobile communication system. Background technique [0002] Since the 1980s, people have applied Code Division Multiple Access (CDMA) technology to the field of mobile communication. Due to its high frequency utilization rate and strong anti-interference ability, it has quickly become a mobile communication system with vitality and application prospects. Currently the world's attention is focused on the third generation mobile communication systems, such as the International Mobile Telecommunications System 2000 (IMT-2000) of the International Telecommunications Union (ITU) or the European Mobile Telecommunications System (UMTS). In the third-generation mobile communication system, it has become a consensus to adopt CDMA technology. Among them, WCDMA, as one of the im...
