Abstract

Automatic registration and/or deregistration from a registry such as a UDDI registry based on the connectivity of a device, such as a mobile device, with an access point. Connectivity may be determined in various ways, including changing power state, entering/leaving a service area of the access point, etc. The access point may contain a registry. Registrations may be provided to a central registry serving a local or private network, and may also be propagated to a global registry. Registries may only process registrations for proximate devices, e.g., devices within the service area. Similarly, if a mobile device desires a particular service or resource, registries may only search for services or resources provided by devices proximate to the mobile device.

Claims

1. A method for registering devices with a first registry, the first registry being searchable for registrants advertising a service or a resource, the method comprising:

monitoring a service area for entry of a device within the service area;

determining a service or resource advertised by the device;

automatically registering the device with the first registry, the registering including creating a registration for the device identifying the advertised service or resource.

2. The method of claim 1, further comprising:

automatically deregistering the device from the first registry

3. The method of claim 2, further comprising:

automatically deregistering the device from the first registry responsive to one or more of the following state changes for the device;

going to sleep, losing power, rebooting, and leaving the service area.

4. The method of claim 1, further comprising:

an access point communicatively coupling the device and the first registry; and

automatically deregistering the device from the first registry if the access point loses communication with the device.

5. The method of claim 1, further comprising:

an access point providing the device with a communication address having an expiration; and

automatically deregistering the device from the first registry if the device is unavailable to communicate with the access point on the expiration of the communication address.

6. The method of claim 5, further comprising:

automatically extending the expiration.

7. The method of claim 1, further comprising:

performing the method with an access point.

8. The method of claim 7, further comprising:

disposing the first registry within the access point.

9. The method of claim 1, further comprising:

disposing the first registry within an access point for devices; and

only automatically registering the device if attached to the access point.

10. The method of claim 1, wherein the registration is short-lived.

11. The method of claim 1, wherein advertising the service or resource comprises the device offering the service or resource for use by other devices.

12. The method of claim 1, wherein advertising the service or resource comprises the device identifying a service or resource desired from another device.

13. The method of claim 1, further comprising:

searching the first registry for the advertised service or resource.

14. The method of claim 1, wherein the first registry comprises a selected one of a UDDI service directory or other directory of services”

?

15. The method of claim 1, further comprising:

detecting whether the device, on entering the service area, announced the service or resource advertised by the device.

16. The method of claim 1, further comprising:

querying the device, on its entering its the service area, for the service or resource advertised by the device.

17. The method of claim 1, further comprising:

determining whether the service or resource advertised by the device is unavailable from another device within the service area.

18. A system, comprising:

a device operable to advertise a service or a resource;

a first registry, the registry being searchable for registrants advertising services or resources; and

a first access point communicatively coupled with both the device and the first registry, the access point having a service area, wherein the first access point is operable to perform;

monitoring the service area for entry therein of the device;

determining a service or resource advertised by the device; and

automatically registering the device with the first registry.

19. The system of claim 18, wherein the first registry is disposed within the first access point.

20. The system of claim 19, further comprising:

a second access point;

a second registry disposed within the second access point and being searchable for registrants advertising services or resources; and

a private network communicatively coupling the first and second access points.

21. The system of claim 18, further comprising:

a second access point; and

a private network communicatively coupling the first and second access points;

wherein the first registry is searchable only for services or resources advertised by devices coupled with the first access point.

22. The system of claim 18, further comprising:

a public network communicatively coupled with a global registry; and

a private network communicatively coupled with both the access point and the public network.

23. The system of claim 22, further comprising:

a second access point communicatively coupled with the private network;

wherein the first registry is communicatively coupled with but separate from both the first and second access points.

24. An article comprising a machine-accessible media having associated data, wherein the data, when accessed, results in a machine performing:

monitoring a service area for entry of a device within a service area of a first registry, the first registry being searchable for registrants advertising a service or a resource;

determining a service or resource advertised by the device;

automatically registering the device with the first registry, the registering including creating a registration for the device identifying the advertised service or resource.

25. The article of claim 24 wherein the machine-accessible media further includes data, when accessed, results in the machine performing:

automatically deregistering the device from the first registry.
