Distributed cell balancing
First Claim
1. A load balancing system for dynamic balancing of load between sectors of local sectored cellular base stations, the system comprising:
- a plurality of repeaters for providing local coverage within the sectors, and a switch, for associating between the repeaters and a respective one of said local sectored base stations, and for switching the repeaters between different sectors.

Abstract
A load balancing system for dynamic balancing of load between sectors of a sectored cellular base station, comprises a plurality of repeaters with local coverage in the sectors, and a switching matrix, for associating between the repeaters and the base station, and for allowing the repeaters to be switched between different sectors. If the system uses the base station assigned frequency band for communication with the repeaters then the system can be provided with minimal interference as an add-on to a legacy base station. An add-on may also be provided using microwave frequency and dedicated antennas.

33. A load balancing system for dynamic balancing of load between sectors of local sectored cellular base stations, the system comprising:
-
a plurality of repeaters for providing localized coverage within the sectors, an additional sector at a respective base station for handling repeater traffic, and a switch, for associating between the repeaters and said additional sector.

34. A method of load balancing at a sector-based cellular base station whose traffic has temporary hot spot characteristics, the method comprising:
-
assigning a repeater to at least one of said hotspots, associating said repeater with a switching matrix, connecting said switching matrix to allow switching of said at least one repeater between sectors of said sector-based cellular base station, measuring usage load at respective ones of said sectors, and controlling said switching matrix to switch said at least one repeater between said sectors in order to achieve balancing of said usage load between said sectors.

-
35. A method of upgrading an existing sector-based cellular base station using repeaters, said upgrade to enable dynamic load balancing, the upgrade comprising:
-
attaching a switching matrix to respective sector RF connections of said base station, assigning respective connections of said switching matrix to said repeaters, obtaining an output from said base station indicating sector usage loading, and connecting said obtained output to control said switching matrix to switch said repeaters between said sector RF connections, thereby to enable balancing of repeater-based load between said sectors.

-
36. A method of load balancing between sectors of a cellular base station, the sectors having repeaters, the method comprising:
-
measuring load at respective sectors of the cellular base station, determining whether there are sectors that are overloaded and underloaded, and for each overloaded sector, switching at least one repeater therefrom to another sector. - View Dependent Claims (37, 38, 39, 40)
