Abstract

Communication resources are allocated within a radio communication system in anticipation of expected resource requirements using predictions based on information supplied by a subscriber unit. In one embodiment, the system uses the subscriber unit'"'"'s location history to predict a future location (510, 520, 530). In another embodiment, the system uses radio capability information, along with environment information for the subscriber unit, to predict loading conditions for potential hand-over sites (610, 620, 630), and assigns the subscriber unit to one of the potential hand-over sites based on the predicted loading conditions (640).

Claims

1. A method for optimizing communication resource allocation in a radio communication system, comprising the steps of:

obtaining a predicted future location for a subscriber unit using information supplied by the subscriber unit;

receiving operational capabilities information, comprising a plurality of operating bands and/or a plurality of of operating protocols directly from the subscriber unit;

reallocating communication resources in use by other subscriber units affiliated with a communication site that services the predicted future location, in preparation for arrival by the subscriber unit at the predicted future location, based at least in part on the received operational capabilities information;

allocating communication resources in anticipation of expected resource requirements for the subscriber unit at the predicted future location based on a combination of the predicted future location, and operational capabilities information.

2. The method of claim 1, wherein the step of obtaining a predicted future location, comprises the steps of:

receiving from the subscriber unit a series of transmissions that includes current location information;

maintaining location history information corresponding to the subscriber unit based on the series of transmissions; and

obtaining the predicted future location for the subscriber unit using the location history information.

3. The method of claim 2, wherein the step of obtaining the predicted future location, comprises the steps of obtaining geographic map information containing possible routes for the subscriber unit, comparing the location history information with map information obtained.

4. The method of claim 2, further comprising the steps of:

receiving operating band information from the subscriber unit; and

reallocating communication resources in use by other subscriber units affiliated with a communication site that services the predicted future location, in preparation for arrival by the subscriber unit at the predicted future location, based in part on the operating band information received from the subscriber unit.

5. The method of claim 2, further comprising the steps of:

receiving operating protocol information from the subscriber unit; and

reallocating communication resources in use by other subscriber units affiliated with a communication site that services the predicted future location in preparation for arrival by the subscriber unit at the predicted future location, based in part on the operating protocol information received from the subscriber unit.

6. A method for optimizing system resource allocation in a multi-site radio communication system, comprising:

receiving from a subscriber unit operational capabilities information, including a plurality of operating bands and/or a plurality of operating protocols, and a series of transmissions that include current location information;

maintaining location history information corresponding to the subscriber unit based on the series of transmissions;

predicting a future location pertaining to the subscriber unit using the location history information; and

allocating communication resources in anticipation of expected resource requirements for the subscriber unit at the predicted future location, based on a combination of the predicted future location, and operational capabilities information.

7. The method of claim 6, further comprising the steps of:

receiving signal strength from the subscriber unit; and

allocating communication resources to the subscriber unit based on a combination of the predicted future location, and the signal strength and operational capabilities information.

8. The method of claim 7, wherein the step of allocating communication resources to the subscriber unit comprises the step of reallocating communication resources used by other subscriber units based on a combination of the predicted future location and operational capabilities information received from the subscriber unit.

9. A method, comprising the steps of, as a part of a handover sequence:

receiving, directly from a subscriber unit, radio capability information, including operating band and/or operating protocol;

receiving subscriber unit environment information, including location information, and cell affiliation information;

predicting loading conditions for potential handover sites based on the radio capability information and the location information; and

assigning the subscriber unit to one of the potential handover sites based on the predicted loading conditions.

10. The method of claim 9, further comprising the steps of:

receiving from a subscriber unit a series of transmissions that includes current location information;

maintaining location history information corresponding to the subscriber unit based on the series of transmissions; and

determining potential handover sites using the location history information.
