Abstract

Various embodiments of systems and techniques for providing location-based services (LBS) to a mobile computing device having a dual processor architecture are described. In one or more embodiments, the mobile computing device may comprise or implement hardware and/or software configured to enable LBS and data communications sessions using a single active data stack at any particular point in time. Other embodiments are described and claimed.

Claims

1. An apparatus comprising:

a wireless computing device including a host processor and a radio processor, the wireless computing device to establish at least one of a location-based services (LBS) communications session and a data communications sessions using a single active data stack implemented by at least one of the host processor and the radio processor at any particular point in time;

a host processor data stack to support LBS and data communications sessions;

wherein LBS communications sessions using the host processor data stack are established without preempting data communications sessions using the host processor data stack.

2. The apparatus of claim 1, wherein the active data stack is used to communicate over a network with a position determination entity (PDE).

3. The apparatus of claim 1, wherein the LBS communications session comprises a global positioning system (GPS) communications session.

4. The apparatus of claim 1, wherein:

the host processor comprises at least one LBS application to initiate an LBS communications session and at least one other application to initiate a data communications session; and

the radio processor comprises one or more position determination programs.

5. The apparatus of claim 4, wherein the position determination programs comprise one or more of a position engine, a position engine interface, and a position engine extension.

6. The apparatus of claim 5, wherein the position engine operates in one or more of a standalone mode, a mobile station (MS) assisted mode, and an MS-based mode.

7. The apparatus of claim 6, wherein the LBS application hides a first position fix of the position engine when operating in a standalone mode.

8. The apparatus of claim 4, wherein the host processor comprises a remote LBS application programming interface (API) to one or more of the position determination programs implemented by the radio processor.

9. The apparatus of claim 8, wherein the LBS API comprised an interface to an API handler implemented by the radio processor.

11. (canceled)

12. (canceled)

13. An apparatus comprising:

a wireless computing device including a host processor and a radio processor, the wireless computing device to establish at least one of a location-based services (LBS) communications session and a data communications sessions using a single active data stack implemented by at least one of the host processor and the radio processor at any particular point in time;

a host processor data stack to support LBS and data communications sessions; and

at least one remote data module and wherein LBS communications sessions using the host processor data stack are established through the remote data module.

14. The apparatus of claim 13, further comprising a radio processor data stack to support LBS and data communications sessions, wherein the single active data stack is one of the host processor data stack and the radio processor data stack.

15. The apparatus of claim 14, further comprising one or more of a data API and a data API handler and wherein data communications sessions using the radio processor stack are established through one or more of the data API and the data API handler.

16. A method comprising:

communicating a location request through a host client implemented by a host processor to a radio client implemented by a radio processor;

communicating a preempt request to the host processor to preempt data sessions using a data stack implemented by the host processor;

establishing a location-based services (LBS) communications session to a network entity using a data stack of the radio processor; and

canceling preemption of the data sessions using the data stack implemented by the host processor in response to termination of the LBS communication session.

17. The method of claim 16, further comprising communicating a preempt request to a data preemption module implemented by the radio processor in response to invocation of an LBS communication session by the host client.

18. The method of claim 16, further comprising preventing new data sessions using the data stack of the host processor from being established until termination of the LBS communications session.

19-29. -29. (canceled)

30. A method comprising:

communicating a data request to a radio processor comprising a data stack used to establish a location-based services (LBS) communications session;

establishing a data communications session other than an LBS communications session using the data stack of the radio processor; and

communicating the data request through a data API implemented by a host processor to a data API handler implemented by a radio processor.

32. The method of claim 30, further comprising sharing the data stack on the radio processor with an LBS application.

31. (canceled)

33. A machine-readable storage medium comprising instructions that if executed enable a computing system to:

communicate a location request through a host client implemented by a host processor to a radio client implemented by a radio processor;

communicate a preempt request to the host processor to preempt data sessions using a data stack implemented by the host processor;

establish a location-based services (LBS) communications session to a network entity using a data stack of the radio processor; and

cancel preemption of the data sessions using the data stack implemented by the host processor in response to termination of the LBS communication session.

34. The storage medium of claim 33, further comprising instructions that if executed enable a computing system to communicate a preempt request to a data preemption module implemented by the radio processor in response to invocation of an LBS communication session by the host client.

35. The storage medium of claim 33, further comprising instructions that if executed enable a computing system to prevent new data sessions using the data stack of the host processor from being established until termination of the LBS communications session.

36-45. -45. (canceled)

46. A machine-readable storage medium comprising instructions that if executed enable a computing system to:

communicate a data request to a radio processor comprising a data stack used to establish a location-based services (LBS) communications session; and

establish a data communications session other than an LBS communications session using the data stack of the radio processor; and

communicate the data request through a data API implemented by a host processor to a data API handler implemented by a radio processor.

48. The storage medium of claim 46, further comprising instructions that if executed enable sharing of the data stack on the radio processor with an LBS application.
