Abstract

The invention relates to a method for realizing two-phase measuring optimization of wireless terminal adjacent subdistricts in a wireless communication system, comprising the following steps: acquiring an adjacent subdistrict list by a wireless terminal, storing based on different frequent points, performing time slot synchronous treatment on pilot frequency adjacent subdistricts in the adjacent subdistrict list, acquiring a time slot synchronous treatment result, storing the time slot position information of which the peak value is larger than a preset threshold value of the system, merging time slots by a preset search window of the system, acquiring a merged and converted time slot amount, acquiring down primary scrambling codes and the amount of the down primary scrambling codes in the pilot frequency adjacent subdistricts in the adjacent subdistrict list, measuring based on the above information and storing the measuring result. By adopting the method for realizing two-phase measuring optimization of wireless terminal adjacent subdistricts in a wireless communication system, the search and measurement times can be greatly reduced, the system running efficiency is high, the work performance is stable and reliable, and the application range is wide, thus laying a solid foundation for further development of adjacent subdistrict search technology of the wireless terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to the technical field of measurement of adjacent cells of wireless terminals, and specifically refers to a method for realizing two-stage measurement optimization of adjacent cells of wireless terminals in a wireless communication system. Background technique [0002] In the current wireless communication system, after the wireless terminal (UE) connected to the wireless communication network is turned on normally, it is likely to detect the information of the adjacent cell according to the need, for example, to maintain the information of the inter-frequency cell and to perform hard handover, etc. In preparation, measurements are performed on inter-frequency adjacent cells in adjacent cells. In this case, the downlink primary scrambling code used by inter-frequency adjacent cells is often given through the system broadcast information of the serving cell. [0003] At...
