Resource management apparatus and a method of resource management therefor

Abstract

The invention provides for a resource management apparatus for a cellular communication system wherein the available radio resource is divided into separate partitions, each of which is allocated to a different operator, such as a Mobile Virtual Network Operator. Radio Network Controllers 215, 217 of the cellular communication system comprise independent resource controllers 221, 223, 225, 227 for each operator. The resource controllers 221, 223, 225, 227 allocate radio resource to a subscriber unit 201 in response to an operator identity associated with a service of the subscriber unit, such that different quality of service is achieved for different operators. The resource is allocated from the resource partition of the operator identified. The resource controllers 221, 223, 225, 227 independently control one or more quality of service parameters of the radio access network. Hence, each operator may independently control and manage quality of service and is thereby enabled to differentiate from other operators.

Description

technical field [0001] The present invention relates to a resource management device and its resource management method, in particular to a resource management system for a cellular communication system such as UMTS. Background technique [0002] Fig. 1 shows the principle of a conventional cellular communication system 100 according to the prior art. A geographical area is divided into a plurality of cells 101,103,105,107, each cell being served by a base station 109,111,113,115. The base stations are interconnected by a fixed network capable of transferring data between the base stations 101 , 103 , 105 , 107 . The base station of the cell in which the mobile station is located serves the mobile station over a wireless communication link. In the example of FIG. 1, base station 109 serves mobile station 117 over wireless link 119, base station 111 serves mobile station 121 over wireless link 123, and so on. [0003] When the mobile station is moving, it can move from the...

Problems solved by technology

[0011] The result of the spread spectrum technique used is that the amount of interfering signals within the bandwidth of the narrowband signal cannot be removed by filtering, thus reducing the signal-to-noise ratio of the received signal
