In a multi-site communication system, a communication may be handed off from a first site to a second site in the following manner. Upon request and when a communication resource is available, a communication resource allocator allocates the communication resource to the requesting communication unit located in the first site. The communication resource allocator also identifies a reserved communication resource in each adjacent site to the first site. When the communication unit relocates to the second site of the adjacent sites, the communication resource allocator allocates the reserved communication resource of the second site to the communication unit without a request from the communication unit. |

DETAILED DESCRIPTION I claim: 1.
In a multi-site communication system that includes a plurality of communication units, a plurality of sites, a limited number of communication resources distributed throughout the plurality of sites, and a communication resource allocator that allocates the limited number of communication resources among the plurality of communication units upon request, a method for providing a handoff of a communication occurring in a first site to a second site, the method comprises the steps of: a) receiving, by the communication resource allocator, a request for a communication resource from at least one communication unit located in the first site; b) when a communication resource is available in the first site, allocating, by the communication resource allocator, the communication resource to the at least one communication unit; c) reserving, by the communication resource allocator responsive to the request, a communication resource in adjacent sites to the first site to produce a reserved communication resource in each site of the adjacent sites, wherein each reserved communication resource is available for future use by the at least one communication unit and is available for allocation to another communication unit for a particular communication service from a limited set of communication services; and d) when the at least one communication unit relocates in the second site of the adjacent sites, allocating, by the communication resource allocator, the reserved communication resource in the second site to the at least one communication unit.
2.
In the method of claim 1, step (c) further comprises selecting the reserved communication resource in each site of the adjacent sites based on a resource availability profile.
3.
The method of claim 2 further comprises allocating, prior to allocation to the at least one communication unit, one of the reserved communication resources in one of the adjacent sites to another communication unit for a particular communication service from a limited set of communication services
