In a resource allocator (106), a reserved resource group comprising at least one communication resource is maintained for use in supporting non-queued services. When a request for the at least one non-queued service is received, a communication resource from the reserved resource group is allocated to the request (305). When the reserved resource group becomes depleted, at least one more communication resource is assigned to the reserved resource group with greater preference relative to allocation of communication resources to requests for at least one queued service (307). In a preferred embodiment, a communication resource is assigned to the reserved resource group prior to allocating resources to any queued service requests. Additionally, communication resources (200) having varying grades of service can be accommodated.
