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

Abstract

The invention discloses a method for the interaction of terminals' carrier-information among the wireless network controllers of the multi-frequency carrier system. The information-elements of the carrier frequency, which represent the allocated frequency of the terminals, are increased in the Iur interface-information during the processes of establishing the wireless links, increasing the wireless links, re-configuring the synchronic wireless links or the physical channels, which makes the terminals of DRNC can be controlled by SRNC, so that we can take full advantage of the resources of DRNC Cell. The invention keeps the latter compatibility of single-carrier frequency wireless network controller, which makes the Iur interface of TD-SCDMA system maintain the original capacity and also obtain the capacity of the multi-frequency 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 ...

Problems solved by technology

In this way, when it comes to the management and control of wireless resources across the Iur interface, in the case of a multi-carrier frequency system, the auxiliary carrier frequency in the multi-carrier frequency system cannot perform such figure 2 , 3 , The wireless link establishment process, the wireless link addition process, the synchronous wireless link reconfiguration process and the physical channel reconfiguration process shown in 4 and 5 lead to unreasonable resource allocation and control, and cannot make full use of the resources of the cells under the jurisdiction of the DRNC Auxiliary carrier frequency resources may even lead to the extreme situation where the main carrier frequency resources are tight and the auxiliary carrier frequency resources are not utilized, and the advantages of the multi-carrier frequency system in terms of capacity and communication quality cannot be fully utilized
