Terminal carrier frequency information interactive method between radio network controller of multiple carrier frequency system

Abstract

The invention discloses a method for terminal carrier frequency information interaction between wireless network controllers of a multi-carrier frequency system. In the corresponding Iur interface message, the carrier frequency information element used to indicate the frequency point allocated by the terminal is added, so that the SRNC can control the terminal in the DRNC, so that the resources of the cell in the DRNC can be fully utilized, and the capacity and communication of the multi-carrier frequency system can be utilized Quality advantage. The method of the present invention maintains backward compatibility for the original wireless network controller supporting single-carrier frequency technology developed according to the previous agreement, so that the Iur interface of the TD-SCDMA system maintains the ability to work under the original single-frequency point system configuration , and also has the ability to work under the configuration of the multi-frequency point system, so as to meet the mobility management requirements of the terminal on the Iur interface of the multi-frequency point system.

Description

technical field [0001] The present invention relates to mobile communication technology, and more specifically, the present invention relates to a multi-carrier frequency TD-SCDMA mobile communication system to realize terminal carrier frequency information interaction between a drift radio network controller and a serving radio network controller through an Iur interface Methods. Background technique [0002] TD-SCDMA is one of the three main standards of the rapidly developing third-generation mobile communication. It is a code-division multiple access-based system that adopts time-division duplex mode and ensures that all terminal signals reach the base station synchronously in the uplink direction. The mobile communication system is also called time division-synchronous code division multiple access mobile communication system. The TD-SCDMA system is standardized by the Third Generation Partnership Project (3GPP). For a detailed description of this system, please refer ...
