Abstract

The present disclosure presents a method and apparatus for identifying an access point (AP) for selection by an access terminal (AT). For example, the method may include receiving a probe request by one or more APs from an AT, wherein the probe request is broadcasted by the AT to the one or more APs, generating load information and Received Signal Strength Indicator (RSSI) values of the probe request at the one or more APs, identifying an AP of the one or more APs for selection by the AT, wherein the AP for selection by the AT is identified by the one or more APs based at least on the load information and RSSI values generated at the one or more APs, and transmitting information of an AP identified by the one or more APs to the AT. As such, an improved mechanism for selecting an access point may be achieved.

Claims (34)

1. A method of identifying an access point (AP) for selection by an access terminal (AT), comprising:

receiving, at an AP of one or more APs, a probe request broadcasted by the AT to the one or more APs, wherein the AP and the AT are at different versions of Hotspot specifications;

generating, at the AP, load information and Received Signal Strength Indicator (RSSI) values of the probe request received from the AT, wherein the load information at the AP is generated as a utility function of at least one of a number of ATs connected to the AP, traffic on the AP, last association event, latency, or backhaul quality;

transmitting, from the AP, a probe response to the AT in response to determining that the AP has a highest value of the utility function among the one or more APs; and

transmitting information of the AP to the AT.

2. The method of claim 1 , wherein the one or more APs are listed based on utility function values.

3. The method of claim 1 , further comprising:

receiving rankings of the one or more APs from a central server.

4. An apparatus for identifying an access point (AP) for selection by an access terminal (AT), comprising:

a memory configured to store data; and

one or more processors communicatively coupled with the memory, wherein the one or more processors and the memory are configured to:

receive, at an AP of one or more APs, a probe request broadcasted by the AT to the one or more APs, wherein the AP and the AT are at different versions of Hotspot specifications;

generate, at the AP, load information and Received Signal Strength Indicator (RSSI) values of the probe request received from the AT, wherein the load information at the AP is generated as a utility function of at least one of a number of ATs connected to the AP, traffic on the AP, last association event, latency, or backhaul quality;

transmit, from the AP, a probe response to the AT in response to determining that the AP has a highest value of the utility function among the one or more APs; and

transmit information of the AP to the AT.

5. The apparatus of claim 4 , wherein the one or more APs are listed based on utility function values.

6. The apparatus of claim 4 , wherein the one or more processors and the memory are further configured to:

receive rankings of the one or more APs from a central server based on utility function values.

7. An apparatus for identifying an access point (AP) for selection by an access terminal (AT), comprising:

means for receiving, at an AP of one or more APs, a probe request broadcasted by the AT to the one or more APs, wherein the AP and the AT are at different versions of Hotspot specifications;

means for generating, at the AP, load information and Received Signal Strength Indicator (RSSI) values of the probe request received from the AT, wherein the load information at the AP is generated as a utility function of at least one of a number of ATs connected to the AP, traffic on the AP, last association event, latency, or backhaul quality;

means for transmitting, from the AP, a probe response to the AT in response to determining that the AP has a highest value of the utility function among the one or more APs; and

means transmitting information of the AP to the AT.

8. The apparatus of claim 7 , wherein the one or more APs are listed based on utility function values.

9. The apparatus of claim 7 , further comprising:

means for receiving rankings of the one or more APs from a central server.

10. A non-transitory computer readable medium storing computer executable code for identifying an access point (AP) for selection by an access terminal (AT), comprising:

code for receiving, at an AP of one or more APs, a probe request broadcasted by the AT to the one or more APs, wherein the AP and the AT are at different versions of Hotspot specifications;

code for generating, at the AP, load information and Received Signal Strength Indicator (RSSI) values of the probe request received from the AT, wherein the load information at the AP is generated as a utility function of at least one of a number of ATs connected to the AP, traffic on the AP, last association event, latency, or backhaul quality;

code for transmitting, from the AP, a probe response to the AT in response to determining that the AP has a highest value of the utility function among the one or more APs; and

code for transmitting information of the AP to the AT.

11. The computer readable medium of claim 10 , wherein the one or more APs are listed based on utility function values.

12. The computer readable medium of claim 10 , further comprising:

code for receiving rankings of the one or more APs from a central server.
