Patent ID: 6954645

Claim:
A system for channel allocation in multi-band wireless network, comprising: a plurality of microcell base stations, providing a plurality of microcell channels; a macrocell base station, providing a plurality of macrocell channels, wherein the radio coverage of the macrocell base station is overlaid with that of the microcell base stations; a mobile station, capable of making and receiving a call by using a channel from the microcell channels and the macrocell channels; and a channel allocation center, capable of performing repacking on demand (RoD) scheme for allocating a first one of the macrocell channels and the microcell channels to a first one of the mobile stations for a call; wherein the RoD scheme comprises: determining whether there are any idle radio channels provided by one of the microcell base stations for the mobile station; if so, allocating an idle radio channel provided by a first one of the microcell base stations to the mobile station, and then ending the scheme; if not, proceeding to the following steps; determining whether there are any idle radio channels provided by the macrocell base station for the mobile station; if so, allocating an idle radio channel provided by the macrocell base station to the mobile station, and then ending the scheme; if not, proceeding to the following steps; determining whether there are any available repacking candidates in the macrocell base station for the mobile station; if so, selecting a repacking candidate and executing a handover of the repacking candidate from the macrocell base station to the microcell base station of the repacking candidate, and allocating the macrocell channel reclaimed from the repacking candidate to the mobile station, and then ending the scheme; if not, ending the scheme if no idle radio channel is available.
