Abstract

Systems and methods for communicating in a wireless communication system are described. Various processes for reducing the initial link set up time are described. In one aspect a method in a wireless communication system is provided. The method includes providing a network service configured to communicate via a plurality of channels. The method further includes determining a characteristic of the network service comprising a load value for each of the plurality of channels. The method further includes transmitting an identifier of the characteristic of the network service for obtaining the network service in the wireless communication system.

Claims

1. A method of reducing signaling in a wireless communication system, the method comprising:

receiving, at a wireless communication device from a network service provider, an identifier and a characteristic for each of one or more network service devices for obtaining a network service from one or more network services in the wireless communication system, each network service device configured to communicate via a plurality of wireless local area network channels provided by the devices, and the characteristic for each of the one or more network service devices comprising a load value for each of the plurality of channels provided by the devices;

selecting, at the wireless communication device, a network service device of the one or more network service devices to associate with based on the received identifiers and characteristics, wherein the received identifiers comprise an identifier that indicates that no new associations are being accepted for an associated network service device; and

transmitting, from the wireless communication device to a provider of the selected network service device, a message to associate with the selected network service device.

2. The method of claim 1, wherein the load value for each of the plurality of channels is determined by calculating the load value over a period of time based on at least one of a number of access requests for each channel, a quantity of data communicated by each channel, a number of devices accessing each channel, and a number of access responses for each channel.

3. The method of claim 1, wherein the received identifiers comprise an identifier that is included in a beacon signal.

4. The method of claim 1, wherein the load value for each of the plurality of channels is determined based on at least one of a number of access requests for each channel, a quantity of data communicated by each channel, a number of devices accessing each channel, and a number of access responses for each channel.

5. The method of claim 4, wherein selecting the network service device comprises:

identifying the network service associated with the lowest load value as compared to other network services of the one or more network service devices; and

selecting the identified network service.

6. The method of claim 4, wherein selecting the network service device comprises:

obtaining a threshold load value; and

selecting the network service based on a comparison between the load value for each of the one or more network services and the threshold value.

7. The method of claim 6, wherein the selected network service device comprises the network service having a load value less than the threshold value.

8. The method of claim 1, wherein the one or more network services are provided by a plurality of networks.

9. The method of claim 1, wherein the load value for each of the plurality of channels is determined based on at least one of a number of access requests for each channel and a number of access responses for each channel.

10. The method of claim 1, wherein selecting the network service device is further based on the indication that no new associations are being accepted.

11. The method of claim 1, further comprising transmitting a probe request, and wherein the received identifiers comprise an identifier that is received via a probe response.

12. A device configured to reduce signaling in a wireless communication system, the device comprising:

a receiver configured to receive, from a network service provider, an identifier and a characteristic for each of one or more network service devices for obtaining a network service from one or more network services in the wireless communication system, each network service device configured to communicate via a plurality of wireless local area network channels provided by the devices, and the characteristic for each of the one or more network service devices comprising a load value for each of the plurality of channels provided by the devices;

a service selection circuit configured to select a network service device of the one or more network service devices to associate with based on the received identifiers and characteristics, wherein the received identifiers comprise an identifier that indicates that no new associations are being accepted for an associated network service device; and

a transmitter configured to transmit, from the device to a provider of the selected network service device, a message to associate with the selected network service device.

13. The device of claim 12, wherein the load value for each of the plurality of channels is determined by calculating the load value over a period of time based on at least one of a number of access requests for each channel, a quantity of data communicated by each channel, a number of devices accessing each channel, and a number of access responses for each channel.

14. The device of claim 12, wherein the received identifiers comprise an identifier that is included in a beacon signal.

15. The device of claim 12, wherein the load value for each of the plurality of channels is determined based on at least one of a number of access requests for each channel, a quantity of data communicated by each channel, a number of devices accessing each channel, and a number of access responses for each channel.

16. The device of claim 15, wherein the service selection circuit is configured to select the network service device by being configured to:

identify the network service associated with the lowest load value as compared to other network services of the one or more network service devices; and

select the identified network service.

17. The device of claim 15, wherein the service selection circuit is configured to select the network service device by being configured to:

obtain a threshold load value; and

select the network service based on a comparison between the load value for each of the one or more network services and the threshold value.

18. The device of claim 17, wherein the selected network service device comprises the network service having a load value less than the threshold value.

19. The device of claim 12, wherein the one or more network services are provided by a plurality of networks.

20. The device of claim 12, wherein the load value for each of the plurality of channels is determined based on at least one of a number of access requests for each channel and a number of access responses for each channel.

21. The device of claim 12, wherein the service selection circuit is further configured to select the network service device further based on the indication that no new associations are being accepted.

22. The device of claim 12, wherein the transmitter is further configured to transmit a probe request, and wherein the received identifiers comprise an identifier that is included in a probe response.

23. An apparatus for reducing signaling during link setup in a wireless communication system, the apparatus comprising:
