Abstract

A reservation protocol is provided to enable a client mobile station to make a number of reservations with a number of access points to facilitate its access of a network at a future point in time, as it roams, and subsequently exercise one of the reservations

Claims

1. An apparatus, comprising:

reservation logic designed to exercise a reservation with an access point to access a network, including logic designed to generate and send a request to the access point to exercise the reservation, with the request having a response to a challenge associated with the reservation earlier posted by the access point when the reservation was earlier made with the access point.

2. The apparatus of claim 1, wherein the reservation logic further comprises logic designed to generate the response to the challenge.

3. The apparatus of claim 2, wherein the logic to generate the response comprises logic designed to generate a hash based at least in part on data received from the access point when the reservation was made with the access point.

4. The apparatus of claim 3, wherein the data comprise one or more selected from the group consisting of a random challenge issued by the access point, data associated with an original reservation request submitted by the apparatus to make the reservation, quality of service parameters, and pairwise master key identification between the apparatus and the access point.

5. The apparatus of claim 4, wherein the data associated with an original reservation request comprises one or more selected from the group consisting of the apparatus'"'"'s media access control address, the access point'"'"'s basic service set identifier, and another access point'"'"'s basic service set identifier, the other access point being an access point facilitating the apparatus in accessing the network at the time of submission of the original reservation request.

6. The apparatus of claim 1, wherein the reservation logic further comprises logic designed to generate a reservation request for the reservation and submit the reservation request to the access point via another access point, or directly to the access point, the other access point facilitating the apparatus in accessing the network at the time of submission of the reservation request.

7. The apparatus of claim 6, wherein the reservation request includes one or more selected from the group consisting of the apparatus'"'"'s media access control address, the access point'"'"'s basic service set identifier, and the other access point'"'"'s basic service set identifier.

8. A method to be performed on a mobile station comprising:

submitting a reservation request at a first point in time to make a reservation directly with a first access point, or via a second access point, the reservation to reserve resource on the first access point to facilitate the mobile station in accessing a network in a future point in time, and the second access point facilitating the mobile station in accessing the network at the time of submission of the reservation request; and

submitting a reservation exercise request to the first access point at a second point in time subsequent to the first point in time to exercise the reservation with the first access point, including with the reservation exercise request a response to a challenge associated with the reservation posted by the first access point at the time the reservation was made with the first access point.

9. The method of claim 8, wherein the method further comprises generating the response to the challenge, including generation of a hash based at least in part on data received from the first access point at the time the reservation was made, which includes data associated with the reservation request submitted by the mobile station.

10. An article comprising:

storage medium; and

instructions stored on the storage medium designed to program an apparatus to enable the apparatus to perform the method of claim 8.

11. A system comprising:

a communication interface;

a mass storage;

a memory;

a controller coupled to the communication interface, the memory and the mass storage;

a processor coupled to the controller; and

reservation logic designed to exercise a reservation with an access point to access a network, including logic designed to generate and send a request to the access point to exercise the reservation, with the request having a response to a challenge associated with the reservation earlier posted by the access point when the reservation was made with the access point, the reservation logic being either disposed in the memory or integrated with the controller.

12. The system of claim 11, wherein the reservation logic further comprises logic designed to generate a reservation request for the reservation and submit the reservation request to the access point via another access point, or directly to the access point, the other access point facilitating the apparatus in accessing the network at the time of submission of the reservation request, the reservation request including one or more selected from the group consisting of the system'"'"'s media access control address, the access point'"'"'s basic service set identifier, and the other access point'"'"'s basic service set identifier.

13. The system of claim 11, wherein the system further comprises a component coupled to the controller, and the reservation logic is integrated with the component instead.

14. An apparatus comprising:

first and second communication interfaces to couple the apparatus to a network and to communicate with a client mobile station respectively;

access logic coupled to the first and second communication interfaces, and designed to facilitate the client mobile station in accessing the network; and

reservation logic coupled to the access logic, and designed to facilitate the client mobile station in making reservation with another apparatus to facilitate the client mobile station to access the network at a future point in time, while the client mobile station is being facilitated by the access logic in accessing the network, including logic designed to regulate at least a number of reservations the client mobile station can made with various apparatuses.

15. The apparatus of claim 14, wherein the regulation logic comprises logic designed to allow the reservation to be made with the other apparatus, only if the client mobile station has a number of reservations with various apparatuses that is lower than a permissible maximum of reservations with other apparatuses.

16. An apparatus comprising:

first and second communication interfaces to couple the apparatus to a network and to communicate with a client mobile station respectively;

access logic coupled to the first and second communication interfaces, and designed to facilitate the client mobile station in accessing the network; and

reservation logic coupled to the access logic, and designed to facilitate the client mobile station in exercising a reservation previously made with the apparatus to facilitate the client mobile station in accessing the network, including logic designed to determine whether the client mobile station has provided a proper response to a challenge associated with the reservation earlier posted by the apparatus when the reservation was made with the apparatus.

17. The apparatus of claim 16, wherein the logic to determine includes logic designed to determine whether a hash submitted by the client mobile station as part of an attempt to exercise the reservation is a properly generated hash that is based at least in part on data provided by the apparatus at the time the reservation was made, which includes data associated with an original reservation request submitted by the client mobile station.

21. The apparatus of claim 16, wherein the reservation logic further comprises logic designed to facilitate the client mobile station in making another reservation with another apparatus, while the client mobile station is being facilitated by the access logic in accessing the network, to facilitate the client mobile station to access the network at a future point in time, including logic designed to regulate at least a number of reservations the client mobile station can made with other apparatuses.
