reallocating a different portion of the shared resources of the high speed packet access channel to the user device in response to the user device selecting a second service option from the second plurality of service options for continuing to exchange data associated with the same first application or service over the high speed packet access channel, wherein the availability of the shared resources is based on a determined amount of shared resources under consideration for allocation in response to a plurality of service requests from a plurality of user devices, and the method further comprises determining the plurality of costs based on at least one of;

a percentage utilization of the shared resources being allocated to service the plurality of service requests;

a subscription plan associated with the user device;

an amount of revenue to be generated by allocation of the shared resources to service the plurality of service requests;

or

an overall service delivery quality resulting from allocating the shared resources to service the plurality of service requests.

2. A method as defined in claim 1 wherein the high speed packet access channel comprises a high speed downlink packet access channel in a wideband code division multiple access network.

3. A method as defined in claim 1 wherein the shared resources comprise a plurality of time slots and a plurality of channel codes capable of transmitting a plurality of data streams over the high speed packet access channel, and wherein allocating the at least a portion of the shared resources of the high speed packet access channel to the user device comprises selecting an appropriate number of at least one of the plurality of time slots or the plurality of channel codes to support the selected service option.

4. A method as defined in claim 1 further comprising providing the information to the user device in response to a request from the user device for a description of available service options corresponding to a particular application from a plurality of available applications.

5. A method as defined in claim 1 wherein allocating at least a portion of the shared resources to the user device according to the first service option comprises:

scheduling transmission of the data to be exchanged; and

allocating one or more time slots and one or more channel codes of the high speed packet access channel based on the first service option.

6. A method as defined in claim 1 wherein the first service option is selected from the first plurality of service options based on at least one of a subscription plan associated with a user of the user device or a response received from the user device.

7. A method as defined in claim 1 wherein the second plurality of costs are determined based on an updated availability of the shared resources.

8. A method as defined in claim 1 wherein the second plurality of costs is provided to the user device in response to a request from the user device.

9. An apparatus to allocate shared resources of a high speed packet access channel, the apparatus comprising:

a resource processor to determine a plurality of costs associated with a plurality of service options for exchanging data with a user device over a high speed packet access channel, the plurality of service options specified in signaling received from the user device, the plurality of costs determined based on an expected future utilization of the shared resources including an amount of the shared resources not yet allocated but under consideration for future allocation to a plurality of user devices in response to a plurality of service requests from the plurality of user devices, wherein the resource processor is to determine the plurality of costs associated with the plurality of service options based on at least one of;

a percentage utilization of the shared resources being allocated to service the plurality of service requests;

a subscription plan associated with the user device;

an amount of revenue to be generated by allocation of the shared resources to service the plurality of service requests;

or

an overall service delivery quality resulting from allocating the shared resources to service the plurality of service requests; and

a resource allocator to;

allocate at least a portion of the shared resources of the high speed packet access channel to the user device according to a selected service option from the plurality of service options; and

reallocate a different portion of the shared resources of the high speed packet access channel to the user device according to a second service option selected from a second plurality of service options for continuing to exchange data over the high speed packet access channel, wherein the resource processor is to determine a second plurality of costs associated with the second plurality of service options.

10. An apparatus as defined in claim 9 further comprising a scheduler to schedule transmission of data packets to the user device according to the at least a portion of the shared resources of the high speed packet access channel allocated to the user device by the resource allocator.

11. An apparatus as defined in claim 9 wherein the shared resources comprise a plurality of time slots and a plurality of channel codes capable of transmitting a plurality of data streams over the high speed packet access channel, and wherein the resource allocator is configured to select an appropriate number of at least one of the plurality of time slots or the plurality of channel codes to support the selected service option.

12. An apparatus as defined in claim 9 wherein the resource processor is to determine the plurality of costs associated with the plurality of service options based on an amount of shared resources already allocated to the plurality of user devices.

13. An apparatus as defined in claim 9 wherein the high speed packet access channel comprises a high speed downlink packet access channel in a wideband code division multiple access network.

14. A user device for exchanging data over a high speed packet access channel, the user device comprising:

a resource negotiator to;

signal first information to a network specifying a first plurality of service options for exchanging data over the high speed packet access channel and for which a first plurality of costs are to be determined; and

obtain the first plurality of costs from the network, the first plurality of costs determined based on an availability of shared resources of the high speed packet access channel, wherein the availability of the shared resources is based on a determined amount of shared resources under consideration for allocation in response to a plurality of service requests from a plurality of user devices, and the plurality of costs is based on at least one of;

a percentage utilization of the shared resources being allocated to service the plurality of service requests;
