Abstract:
1. Apparatus for use in a mobile radio communication system having a plurality of base stations, each base station associated with a cell, and a plurality of mobile stations, comprising: a radio resource administrator for providing to mobile stations a list of candidate radio channels associated with different base stations and receiving from a mobile station a request for a radio connection having a requested bandwidth; a radio quality supervisor, coupled to the radio resource administrator, for regularly receiving from the mobile stations signal quality measurements associated with each candidate radio channel; a session quality supervisor, coupled to the radio resource administrator, for determining and providing to the radio resource administrator an available bandwidth for each candidate radio channel that can be allocated without decreasing a quality of service for existing traffic on that radio channel; an interference supervisor, coupled to the radio resource administrator, for receiving current signal quality measurements from the mobile stations for each base station, determining cell-to-cell interference information based on the received current signal quality measurements, and estimating and providing to the radio resource administrator an interference impact the requested radio connection on one of the candidate radio channels would have on existing radio connections based on the cell-to-cell interference information, wherein the radio resource administrator is configured to allocate a candidate radio channel for the requested radio connection based on information received from the radio quality supervisor, the session quality supervisor, and the interference supervisor.
