Communication system, communication unit and method of power saving therein

摘要

A communication system ( 200 ) comprises a system management function ( 246 ) for managing base-site resources and system throughput of data. The system management function ( 246 ) defines a number of resources. The system management function ( 236 ), such as a radio network controller, comprises a data throughput identification function to identify one or more bottleneck resources from a sub-set of system resources involved in the system's data throughput. A method of reducing power consumption (MIPS) in a system management function ( 236 ) and a radio network controller ( 236 ) are also provided. The identification of a bottleneck resource helps determine whether MIPS could be saved by not performing one or more QoS management algorithms, the benefit from which is reduced due to the bottleneck resource.
