Abstract

Techniques for supporting communication for a wireless device are described. In an aspect, an embedded connection manager may reside within a radio subsystem and support communication for the wireless device. The connection manager may receive at least one connection request sent by at least one application, select at least one radio for use, and provide the selected radio(s) to the application(s). In another aspect, communication may be supported using multiple radios. M out of N available radios may be selected for use, and K applications may be mapped to the M selected radios, where M>1, N>1, and K≧1. In yet another aspect, communication may be supported using profiles, which may define the operation of the wireless device to obtain connectivity. In yet another aspect, communication may be supported with auxiliary services, which are services that assist the wireless device to obtain connectivity.

Claims

1. A method of supporting communication, comprising:

communicating between a connection manager and at least one application via a host interface, the connection manager being embedded within a radio subsystem for a wireless device, the wireless device comprising at least one profile including connectivity preferences for the wireless device;

receiving at least one connection request sent by the at least one application to the connection manager, the at least one connection request configured to trigger use of the at least one profile;

selecting, using the connection manager, at least one radio from a plurality of radios to use for the at least one application in response to the at least one connection request based on operating factors of the plurality of radios; and

providing the at least one selected radio from the connection manager to the at least one application.

2. The method of claim 1, wherein the selecting at least one radio comprises

determining a set of radios available for use, and

selecting a subset of the available radios as the at least one selected radio.

3. The method of claim 1, wherein the selecting at least one radio comprises

determining a set of radios available for use, and

providing the set of available radios as the at least one selected radio.

4. The method of claim 1, wherein the selecting at least one radio comprises communicating with a radio controller to obtain measurements for available radios, and selection the at least one radio based on the measurements for the available radios.

5. The method of claim 4, wherein the selecting at least one radio comprises

determining quality of a plurality of radio links, each radio link corresponding to a communication channel from an available radio on the wireless device to a station in a wireless network, and

selecting the at least one radio based on the quality of the plurality of radio links.

6. The method of claim 4, wherein the selecting at least one radio comprises

determining quality of a plurality of data paths, each data path corresponding to an end-to-end communication channel via an available radio on the wireless device to an endpoint transferring data with the wireless device, and

selecting the at least one radio based on the quality of the plurality of data paths.

7. The method of claim 1, wherein the selecting at least one radio comprises

determining capabilities of radios available for use, and

selecting the at least one radio from among the available radios based on the capabilities of the available radios and requirements of the at least one application.

8. The method of claim 1, further comprising:

communicating between the connection manager and a wireless network for authentication, or registration, or both.

9. The method of claim 1, wherein the radio subsystem comprises a wireless data card, a modem chip, or a modem chipset.

10. The method of claim 1, wherein the connection manager operates below and independently of an operating system on the wireless device.

11. An apparatus for supporting communication, comprising:

means for communicating between a connection manager and at least one application via a host interface, the connection manager being embedded within a radio subsystem for a wireless device, the wireless device comprising at least one profile including connectivity preferences for the wireless device;

means for receiving at least one connection request sent by the at least one application to the connection manager, the at least one connection request configured to trigger the use of the at least one profile;

means for selecting, using the connection manager, at least one radio from a plurality of radios to use for the at least one application in response to the at least one connection request based on operating factors of the plurality of radios; and

means for providing the at least one selected radio from the connection manager to the at least one application.

12. The apparatus of claim 11, wherein the means for selecting at least one radio comprises

means for determining a set of radios available for use, and

means for selecting a subset of the available radios as the at least one selected radio.

13. The apparatus of claim 11, wherein the means for selecting at least one radio comprises

means for determining a set of radios available for use, and

means for providing the set of available radios as the at least one selected radio.

14. The apparatus of claim 11, wherein the means for selecting at least one radio comprises

means for determining quality of a plurality of radio links, each radio link corresponding to a communication channel from an available radio on the wireless device to a station in a wireless network, and

means for selecting the at least one radio based on the quality of the plurality of radio links.

15. An apparatus for supporting communication, comprising:

at least one processor configured

to communicate between a connection manager and at least one application via a host interface, the connection manager being embedded within a radio subsystem for a wireless device, the wireless device comprising at least one profile including connectivity preferences for the wireless device,

to receive at least one connection request sent by the at least one application to the connection manager, the at least one connection request configured to trigger the use of the at least one profile,

to select, using the connection manager, at least one radio from a plurality of radios to use for the at least one application in response to the at least one connection request based on operating factors of the plurality of radios, and

to provide the at least one selected radio from the connection manager to the at least one application.

16. The apparatus of claim 15, wherein the at least one processor is configured to determine a set of radios available for use and to select a subset of the available radios as the at least one selected radio.

17. The apparatus of claim 15, wherein the at least one processor is configured to determine a set of radios available for use and to provide the set of available radios as the at least one selected radio.

18. The apparatus of claim 15, wherein the at least one processor is configured to determine quality of a plurality of radio links, each radio link corresponding to a communication channel from an available radio on the wireless device to a station in a wireless network, and to select the at least one radio based on the quality of the plurality of radio links.

19. A computer program product, comprising:

a non-transitory computer-readable medium comprising;

code for causing at least one computer to communicate between a connection manager and at least one application via a host interface, the connection manager being embedded within a radio subsystem for a wireless device, the wireless device comprising at least one profile including connectivity preferences for the wireless device,
