Abstract

As a communication is engaged upon a mobile device, data can be relayed through a base station. Determining which base station the mobile device should use can be based upon location and velocity of the mobile device. Other factors can be taken into account in determining a base station, such as power output of the mobile device and base station, load balancing, mobile device trends, and the like. Based upon these various factors, a determination can be made if the mobile device should transfer base stations.

Claims

1. A method operable upon a wireless communication device for managing handover of a communication, comprising:

identifying metadata relevant to association of a mobile device with a cell of a base station; and

transmitting at least a portion of the identified metadata that is relevant toward determining if a handover should occur, identification or transmission occurs upon the wireless communication device.

2. The method of claim 1, further comprising determining the location of the mobile device, the identified metadata is location of the mobile device, velocity of the mobile device, power level of the mobile device, or a combination thereof.

3. The method of claim 1, further comprising collecting a request for metadata, metadata identification occurs in accordance with the request and transmitting at least a portion of the identified metadata comprises transferring at least a portion of the identified metadata at periodic times.

4. The method of claim 1, further comprising:

setting a level designating a high power output;

measuring a power output of the mobile device; and

determining if the power output is at the high level, upon determining that the output is at the high level metadata identification occurs.

5. An apparatus, comprising:

an identifier that identifies metadata relevant to association of a mobile device with a cell of a base station; and

a transmitter that produces at least a portion of the identified metadata that is relevant toward determining if a handover should occur.

6. The method of claim 5, further comprising an evaluator that determines the location of the mobile device, the identified metadata is location of the mobile device, velocity of the mobile device, power level of the mobile device, or a combination thereof.

7. The method of claim 5, further comprising an obtainer that collects a request for metadata, metadata identification occurs in accordance with the request and production of at least a portion of the identified metadata includes transfer of at least a portion of the identified metadata at periodic times.

8. The method of claim 5, further comprising:

an appraiser that sets a level designating a high power output;

a balancer that measures a power output of the mobile device; and

a resolver that determines if the power output is at the high level, upon determining that the output is at the high level metadata identification occurs.

9. At least one processor configured to manage handover of a communication, comprising:

a first module for identifying detail relevant to association of a mobile device with a cell of a base station; and

a second module for transmitting at least a portion of the identified metadata that is relevant toward determining if a handover should occur.

10. A computer program product, comprising:

a computer-readable medium comprising;

code for causing a computer to identify information relevant to association of a mobile device with a cell of a base station; and

code for causing the computer to transmit at least a portion of the identified metadata that is relevant toward determining if a handover should occur.

11. An apparatus, comprising:

means for identifying metadata relevant to association of a mobile device with a cell of a base station; and

means for transmitting at least a portion of the identified metadata that is relevant toward determining if a handover should occur.

12. A method operable upon a wireless communication device for determining handover of a communication, comprising:

evaluating positioning metadata related to a mobile device; and

determining if the mobile device should transfer from a servicing base station to a neighboring base station, the determination is based at least in part upon a result of the evaluation and the evaluation or determination is performed by the wireless communication device.

13. The method of claim 12, wherein the positioning metadata is location of the mobile device and velocity of the mobile device.

14. The method of claim 12, further comprising:

calculating a freshness level of the positioning metadata; and

establishing if the freshness level is high enough to be relied upon for determining if there should be a mobile device transfer.

15. The method of claim 12, wherein evaluating positioning metadata of a mobile device comprises comparing metadata obtained at different instances.

16. The method of claim 15, wherein determining if the mobile device should transfer from a servicing base station to a neighboring base station comprises resolving if there is a high enough deviation in metadata from the different instances to warrant the transfer.

17. The method of claim 12, further comprising calculating the base station load balancing wherein the determination is based at least in part upon a result of the evaluation and base station load balancing.

18. The method of claim 12, further comprising measuring a power output of the base station wherein the determination is based at least in part upon a result of the evaluation and the power output.

19. An apparatus, comprising:

an analyzer that evaluates positioning metadata related to a mobile device; and

a verifier that determines if the mobile device should transfer from a servicing base station to a neighboring base station, the determination is based at least in part upon a result of the evaluation.

20. The apparatus of claim 19, wherein the positioning metadata is location of the mobile device and velocity of the mobile device.

21. The apparatus of claim 19, further comprising:

a investigator that calculates a freshness level of the positioning metadata; and

a comparator that establishes if the freshness level is high enough to be relied upon for determining if there should be a mobile device transfer.

22. The apparatus of claim 19, wherein the analyzer comprises a distinguisher that compares metadata obtained at different instances.

23. The apparatus of claim 22, wherein the verifier comprises an observer that resolves if there is a high enough deviation in metadata from the different instances to warrant the transfer.

24. The apparatus of claim 19, further comprising a monitor that calculates the base station load balancing the determination is based at least in part upon a result of the evaluation and base station load balancing.

25. The apparatus of claim 19, further comprising an assessor that measures a power output of the base station, the determination is based at least in part upon a result of the evaluation and the power output.

26. At least one processor configured to determine handover of a communication, comprising:
