Problems solved by technology

In the current 3GPP series protocols, only the most necessary information is transmitted to the serving base station controller, including the scrambling code of the cell that is currently handed over successfully, and only a small amount of necessary cell information is transmitted to the serving base station in the message through the Iur interface Controller, this information can only ensure that the most necessary handover actions can be performed, but it cannot meet the needs of the serving base station controller for optimal radio resource management
Many useful information that can promote the efficiency of the cell's radio resource usage are not transmitted to the serving base station controller, so the serving base station controller cannot optimally complete the radio resource management of the cell

Abstract

A method for optimizing the management of radio resources in CDMA system is characterized by that the attribute information of the cell controlled by the controller of the base station connected currently with user is transmited via interface to the controller of the base station to which initial connection is created, and said information is classified and managed in optimized mode, resulting in high utilization rate of radio resources and high QoS.

Description

technical field [0001] The invention relates to a communication system, in particular to a radio resource management optimization method between different nodes in a CDMA cellular mobile communication system. Background technique [0002] CDMA is a spread spectrum communication technology. Spread spectrum communication technology was mainly used in military communication in the early stage, and it will also be widely used in civilian communication due to its excellent performance. Now there are already commercial CDMA cellular mobile communication systems running in the telecommunication network. [0003] In the existing cellular mobile communication system, when a mobile station leaves a cell and enters another cell, the signal received by the mobile station from the original cell must become weaker and weaker, and the signal it receives entering the cell will also become weaker. stronger. In order to maintain the communication quality o...
