Problems solved by technology

[0010] The existing method has the following disadvantages: when there are many neighboring cells not on the same frequency, it needs to consume the processing capacity of the UE, especially when the UE needs to start the compressed mode for measurement, which makes the measurement insufficient, and sometimes the optimal handover is often not obtained target cell
When there are many GSM neighboring cells, it needs to consume the processing power of the UE, especially when the UE needs to start the compressed mode for measurement, the UE measures too many GSM neighboring cells in the limited compressed mode space, making the measurement insufficient, and sometimes often cannot obtain Optimal handover target cell

Embodiment Construction

[0036] The scheme of the present invention will be further explained below in conjunction with the drawings.

[0037] The non-same frequency measurement in the present invention includes different frequency and / or different system measurement. In the process of non-same frequency handover, the measurement of the non-same frequency adjacent cell needs to be started first.

[0038] In the code division multiple access system, the mobile station will carry the RACH (Random Access Channel) additional measurement report of the neighboring cell when it accesses, which provides a basis for the selection of the cell. At other times (such as in the connected state), the signal quality information of neighboring cells can be reported through the same-frequency measurement report in the soft handover process.

[0039] The UE measures the strength value or Ec / No (signal-to-noise ratio) value of the downlink common pilot channel RSCP (Received Signal Code Power) of all cells in the monitoring ...

Abstract

A method for selecting no common frequency measuring adjacent zone to carry out measurement includes using base station controller to structure a reference cell set containing cell resided currently by mobile station and containing other common frequency reference cell being cell satisfying to quality object value and electing out from common frequency measuring report reported up by mobile station, generating no common frequency measuring cell set according to intersection set formed by no common frequency adjacent cell of various cells in reference cell set, sending generated cell set to mobile station for launching no common frequency measurement on cell in no common frequency measuring cell set.

Description

Technical field [0001] The invention relates to a code division multiple access mobile communication system, in particular to a method for selecting non-co-frequency measurement neighboring cells for measurement. Background technique [0002] In the existing cellular mobile communication system, in order to improve the utilization rate of spectrum resources and the capacity of the entire system, the radio frequency power of the base station in the system needs to be limited to a certain range (cell). When a mobile station leaves one cell and enters another cell, the signal of the original cell received by this mobile station must become weaker and weaker, and the signal it receives when it is entering the cell will become stronger. In order to maintain the communication quality of the mobile station, the connection to the mobile station must be switched from the original base station to the newly entered base station with a stronger signal. This is the concept of handover in the ...
