Abstract

Techniques for neighbor list provision in a communication network are described. From an access terminal, a query for potential access points within communication range of the access terminal is received; and neighbor list information is provided to the access terminal. The neighbor list information is associated with available access points capable of providing the access terminal with access to a network.

Claims

1. A method comprising:

generating, for an access terminal at a geographic location, a neighbor list of first access points in a network, with the first access points in the neighbor list being within a communication range of the access terminal at the geographic location;

wherein the first access points in the neighbor list have an absence of support for a communication feature to be accessed by the access terminal at the geographic location;

receiving, at least partly based on the absence of support for the communication feature, a query for an update to the neighbor list to include first other access points that support the communication feature at the geographic location;

determining, in response to the query, one or more second access points in the network that support the communication feature at the geographic location, with the one or more second access points being within the communication range of the access terminal at the geographic location;

updating the neighbor list with the one or more second access points in the network that support the communication feature at the geographic location;

delivering the update to the neighbor list to second other access points in a vicinity of an access point in communication with the access terminal; and

instructing the second other access points in the vicinity to use one or more access technologies to deliver the update to the neighbor list to the access terminal as one or more overhead signaling messages;

wherein at least one of the first access points in the neighbor list differs from at least one of the one or more second access points in the update to the neighbor list.

2. The method of claim 1, wherein the first access points in the neighbor list satisfy one or more criteria.

3. The method of claim 2, wherein the one or more criteria comprise one or more of:

a location, an application service requirement, a hardware specification, a hardware identification number of the access terminal, and a user identification number of a user of the access terminal.

4. The method of claim 1, further comprising:

providing the neighbor list by providing one or more of radio channel information and radio access protocol information.

5. The method of claim 1, further comprising:

delivering the neighbor list to a third access point configured to communicate with the access terminal; and

instructing the third access point to transmit the neighbor list to the access terminal as an overhead signaling message.

6. The method of claim 1, further comprising:

delivering the neighbor list to a third access point located in a communication range of one of the first access points; and

causing the neighbor list to be broadcast to other access terminals via the third access point.

7. The method of claim 1, wherein receiving the query comprises receiving the query over the network.

8. The method of claim 7, wherein receiving the query over the network comprises receiving the query using one or more Internet protocols.

23. The method of claim 1, wherein the one or more second access points in the network that support the communication feature are potential neighboring access points, and wherein the method further comprises:

eliminating one or more of the potential neighboring access points based on an eligibility of the access terminal to obtain service from the potential neighboring access points, wherein the eligibility is based on whether the access terminal has rights granted by service providers to access the potential neighboring access points;

wherein updating comprises;

updating the neighbor list with remaining potential neighboring access points.

9. A system comprising:

one or more processors; and

one or more tangible computer-readable media configured to store instructions that are executable by the one or more processors to perform operations comprising;

generating, for an access terminal at a geographic location, a neighbor list of first access points in a network, with the first access points in the neighbor list being within a communication range of the access terminal at the geographic location;

wherein the first access points in the neighbor list have an absence of support for a communication feature to be accessed by the access terminal at the geographic location;

receiving, at least partly based on the absence of support for the communication feature, a query for an update to the neighbor list to include first other access points that support the communication feature at the geographic location;

determining, in response to the query, one or more second access points in the network that support the communication feature at the geographic location, with the one or more second access points being within the communication range of the access terminal at the geographic location;

updating the neighbor list with the one or more second access points in the network that support the communication feature at the geographic location;

delivering the update to the neighbor list to second other access points in a vicinity of an access point in communication with the access terminal; and

instructing the second other access points in the vicinity to use one or more access technologies to deliver the update to the neighbor list to the access terminal as one or more overhead signaling messages;

wherein at least one of the first access points in the neighbor list differs from at least one of the one or more second access points in the update to the neighbor list.

10. The system of claim 9, wherein at least one of the first access points in the neighbor list comprises a mobile access point.

11. The system of claim 9, wherein at least one of the first access points in the neighbor list is configured to serve a sub-pico cell.

12. The system of claim 9, wherein one of the first access points in the neighbor list is configured to use a first radio access technology, and wherein another one of the first access points in the neighbor list is configured to use a second, different radio access technology.

13. The system of claim 9, wherein the first access points in the neighbor list satisfy one or more criteria.

14. The system of claim 13, wherein the one or more criteria comprise one or more of:

a location, an application service requirement, a hardware specification, a hardware identification number of the access terminal, and a user identification number of a user of the access terminal.

15. The system of claim 9, wherein the operations further comprise:

generating a web page that comprises information indicative of the update to the neighbor list.

16. The system of claim 9, wherein a plurality of communication protocols are used for transmitting the neighbor list, and wherein the plurality of communication protocols comprises at least one of:

HTTP protocols, XML-based protocols, TCP/UDP over IP protocols, SIP messaging, custom-designed protocols, and non-IP-based protocols.

17. One or more non-transitory computer readable media configured to store instructions that are executable by one or more processors to perform operations comprising:

generating, for an access terminal at a geographic location, a neighbor list of first access points in a network, with the first access points in the neighbor list being within a communication range of the access terminal at the geographic location;

wherein the first access points in the neighbor list have an absence of support for a communication feature to be accessed by the access terminal at the geographic location;

receiving, at least partly based on the absence of support for the communication feature, a query for an update to the neighbor list to include first other access points that support the communication feature at the geographic location;

determining, in response to the query, one or more second access points in the network that support the communication feature at the geographic location, with the one or more second access points being within the communication range of the access terminal at the geographic location;

updating the neighbor list with the one or more second access points in the network that support the communication feature at the geographic location;

delivering the update to the neighbor list to second other access points in a vicinity of an access point in communication with the access terminal; and

instructing the second other access points in the vicinity to use one or more access technologies to deliver the update to the neighbor list to the access terminal as one or more overhead signaling messages;

wherein at least one of the first access points in the neighbor list differs from at least one of the one or more second access points in the update to the neighbor list.

18. The one or more non-transitory computer readable media of claim 17, wherein the first access points in the neighbor list satisfy one or more criteria.
