Abstract

A wireless service of a first type is scanned. A first station associated with the first type is selected. A first indicator of expected service conditions associated with the first station is received. Based on the first indicator, a wireless service of a second type is scanned. A second station associated with the second type is selected. A second indicator of expected service conditions associated with the second type is received. Based on the first indicator and the second indicator, one of the first type and second type is selected to receive wireless service.

Claims

1. A method of operating a wireless device to select a wireless network, comprising:

in the wireless device, scanning for a wireless service of a first type;

in the wireless device, selecting a first station associated with the first type;

in the wireless device, receiving a first indicator of expected service conditions associated with the first station;

based on the first indicator, scanning for a wireless service of a second type in the wireless device;

in the wireless device, selecting a second station associated with the second type;

in the wireless device, receiving a second indicator of expected service conditions associated with the second type; and

,

based on the first indicator and the second indicator, selecting one of the first type and second type to provide wireless service for the wireless device.

2. The method of claim 1, wherein the first indicator comprises an indicator associated with signal strength.

3. The method of claim 1, wherein the first indicator comprises an indicator associated with network loading.

4. The method of claim 1, wherein the first indicator comprises an indicator associated with available throughput.

5. The method of claim 1, wherein the first indicator comprises an indicator associated with an available modulation and coding scheme.

6. The method of claim 1, wherein scanning for the wireless service of the first type is performed for a first period of time and scanning for the wireless service of the second type is performed for a second period of time.

7. The method of claim 1, wherein the wireless service of the first type is a high bandwidth wireless service.

8. The method of claim 1, wherein the wireless service of the second type is cellular service.

9. A method of operating a communication system, comprising:

receiving in a first base station, on an access channel associated with a first type of wireless service, a connection request from a wireless device;

in the first base station, determining a profile associated with the wireless device;

in the first base station, based on the profile, allowing the wireless device to request a first indicator of expected service conditions associated with the first type of wireless service;

in the first base station, sending the first indicator of expected service conditions to the wireless device; and

,

sending a second indicator of expected service conditions associated with a second type of wireless service.

10. The method of claim 9, wherein the first indicator of expected service conditions comprises an indicator associated with signal strength.

11. The method of claim 9, wherein first indicator of expected service conditions comprises an indicator associated with network loading.

12. The method of claim 9, wherein the first indicator of expected service conditions comprises an indicator associated with available throughput.

13. The method of claim 9, wherein the first indicator of expected service conditions comprises an indicator associated with an available modulation and coding scheme.

14. The method of claim 9, further comprising:

receiving, on a second access channel associated with the second type of wireless service, a second connection request from the wireless device.

15. The method of claim 9, wherein the first type of wireless service is high bandwidth wireless service.

16. The method of claim 9, wherein the second type of wireless service is a cellular service.

17. A communication system, comprising:

a first base station configured to provide a first type of wireless service, the first base station also configured to receive a first connection request from a wireless device, determine a profile associated with the wireless device, and, based on the profile, allow the wireless device to request a first indicator of expected service conditions and send first indicator of expected service conditions to the wireless device; and

,

a second base station co-located with the first base station and configured to provide a second type of wireless service, the second base station also configured to send a second indicator of expected service conditions associated with the second type of wireless service.

18. The communication system of claim 17, wherein the second base station is also configured to receive a second connection request, associated with the second type of wireless service, from the wireless device.

19. The communication system of claim 17, wherein the wireless device is configured to select a type of wireless service based on the first indicator of expected service conditions.

20. The communication system of claim 17, wherein the wireless device is configured to select the first type of wireless service based on the first indicator of expected service conditions satisfying a criteria.
