1. An apparatus, comprising:
- a receiver of a second area configured to receive channel allocation information in cells corresponding to a first plurality of base stations in a first area controlled by a first plurality of base station controllers of the first area, wherein the channel allocation information comprises at least one of channel status information or cell status information;
a base station controller of the second area being configured to;
control channel allocation in cells corresponding to a second plurality of base stations in the second area, wherein each cell in the first area is sufficiently close to a respective one of the cells in the second area to cause interference; and
take into account the received channel allocation information in the cells in the first area when controlling channel allocation in the cells in the second area to limit interference;
wherein the base station controller of the second area is further configured to take into account the received channel allocation information by selecting a channel assignment to establish a new call based on the received channel allocation information to reduce interference with connections corresponding to the received channel allocation information; and
a co-ordinator to receive the channel allocation information from the first plurality of base station controllers of the first area;
wherein the co-ordinator is provided in a network element separate from the first plurality of base station controllers or the base station controller of the second area.

Abstract
A communication system covering an area, including a plurality of first units. Each of the first units being configured to control the allocation of channels in a part of the area. At least one of the first units being configured to send information relating to channel allocation in the part of the area associated with the at least one first unit to at least one other of the first units. The at least one other of the first means units being configured to take into account the received information when controlling the allocation of channels in the part of the area associated with the at least one other first units.

31. A method, comprising:
-
controlling, by a base station controller, channel allocation in cells corresponding to a first plurality of base stations in a first part of an area; receiving channel allocation information in cells corresponding to a first plurality of base stations in a second part of the area controlled by a first plurality of base station controllers in the second part of the area, wherein each cell in the first area is sufficiently close to a respective one of the cells in the second area to cause interference, wherein the channel allocation information comprises at least one of channel status information or cell status information; and taking into account the received channel allocation information when controlling channel allocation in the cells in the first part of the area to limit interference; wherein taking into account the received channel allocation information further comprises selecting a channel assignment to establish a new call based on the received channel allocation information to reduce interference with connections corresponding to the received channel allocation information; wherein the channel allocation information is received by a co-ordinator provided in a network element separate from the base station controller in the first part or the first plurality of base station controller in the second part. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39)
