A METHOD OF SEARCH CELL AT HAND OVER BETWEEN THE RNCS FOR WCDMA MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a handoff between RNCs in an asynchronous mobile communication system. In the case of a handover request failure of a mobile communication terminal requested by an SRNC, neighboring cell information is provided in a response message to request handover to a neighboring cell having a lot of available resources. This is a cell search method for handover of control period of asynchronous mobile communication system which reduces processing time between RNCs and implements handover smoothly. The present invention has the effect of maintaining the optimal RRM (Radio Resource Management) because the radio resource management belongs to the RNC (DRNC) that has a large number of available resources, and can find the exact target cell (Target Cell), Increasing the utilization of resources has the effect of improving the operational efficiency of the WCDMA mobile communication system. In addition, the present invention takes less time according to the handover procedure and does not need to operate an unnecessary compressed mode.;Handover, SRNC, DRNC, Radio Link Setup / Radio Link Addition Failed messages.
