METHOD AND SYSTEM FOR WIRELESS COMMUNICATION
First Claim
1. A method for bandwidth allocation in a wireless communication system, the method comprising of:
- Assigning at least one specific frequency, called hand-off frequency, to one or more base station called as hand-off base station (HBS) located within the service area, for handing off subscriber stations between at least two cells, wherein the said hand-off frequency is not used by the base station of the said two cells for serving subscriber stations and wherein, hand-off is triggered when received signal strength at serving base station, hand-off base station or at subscriber station is below acceptable value.Assigning frequencies, other than the hand-off frequency, to the base stations called as serving base stations (SBS) located within the cells of the service area, for serving the subscriber stations within the cell.

Abstract
A method and system for bandwidth allocation in a wireless communication system, by assigning at least one specific frequency, called hand-off frequency, to one or more base station called as hand-off base station (HBS) located within the service area, for handing off subscriber stations between at least two cells, wherein the said hand-off frequency is not used by the base station of the said two cells for serving subscriber stations and wherein, hand-off is triggered when received signal strength at serving base station, hand-off base station or at subscriber station is below acceptable value and assigning frequencies, other than the hand-off frequency, to the base stations called as serving base stations (SBS) located within the cells of the service area, for serving the subscriber stations within the cell. The method further comprising of regulating the signal transmission strength of the serving base station.

6. A wireless communication system consisting of a plurality of base stations each associated with a cell, the plurality of cells being separated by a distance such that each cell has a complete coverage area surrounding its base station and a hand-off region in between complete coverage area, the system comprising:
-
means for assigning hand-off frequency to one or more base station called as hand-off base station located within the service area; means for assigning frequencies other than hand-off frequency to the hand-off base station in its capacity as serving base station and assigning frequencies other than hand-off frequency to other base stations called as serving base stations located within the service area; means for selecting one or more dedicated hand-off base station, located strategically within the service area such that the hand-off frequency transmitted with certain transmission power, covers the entire service area; and means for selecting one or more hand-off base station from among the serving base stations in a service area, such that the hand-off frequency transmitted with certain power, covers the entire service area.

7. A hand-off base station, in a wireless communication network comprising;
-
A transceiver; for communicating on hand-off frequency with the subscriber station on the hand-off region; for communicating on frequency other than hand-off frequency in the capacity of serving base station with subscriber stations located within its cell; and
.A processor for understanding and processing the received uplink communication from the subscriber stations on the hand-off frequency and for understanding and processing the communication received from other serving base stations located within the service area; and A memory for retaining instructions for executing functions associated with the transceivers and processor/processors, as well as measured or computed data that may be generated during executing such functions.
