Abstract

A system for authorizing services in wireless devices based on a type of service requested and a location of the wireless device is provided. For example, in a wireless telephony system, when a session is set up via an Internet Protocol-based system, an application server queries a location service for the location of the handset requesting the service. If the handset or the receiving handset is in a location that is not authorized for the requested service based on the position of the handset, the connection is not enabled. A message may be transmitted to the sending handset to inform a user that the service is not authorized for the location.

Claims

1. A method comprising:

receiving, by a mobile handset, from a base transceiver station of a mobile communication network via a cell broadcast, data comprising a service provided via the mobile communication network and an area within which the service is unauthorized, wherein the base transceiver station transmits the data to a plurality of mobile handsets via the cell broadcast, and wherein the mobile handset is one of the plurality of mobile handsets;

receiving, by the mobile handset, from a user of the mobile handset, a request for the service;

determining, by the mobile handset, a location of the mobile handset;

determining, by the mobile handset, based on the data received via the cell broadcast, whether the service is unauthorized at the location of the mobile handset; and

in response to the request for the service and to determining that the service is unauthorized at the location of the mobile handset, blocking, by the mobile handset, the service.

2. The method of claim 1, wherein the location of the mobile handset is determined based on a local ability within the mobile handset.

3. The method of claim 1, further comprising allowing the service, even though the service is unauthorized at the location of the mobile handset, in response to the service being associated with an emergency.

4. The method of claim 1, wherein the service is associated with at least one of a streaming of audio, a streaming of video, or peer-to-peer communications.

5. The method of claim 4, wherein blocking the service comprises blocking the streaming of audio from the mobile handset.

6. The method of claim 4, wherein blocking the service comprises blocking the streaming of video from the mobile handset.

7. The method of claim 1, wherein the data received by the mobile handset via the cell broadcast is stored at the mobile handset in a first-in-first-out order.

8. A method comprising:

receiving, by a mobile handset, from a base transceiver station of a mobile communication network via a cell broadcast, data comprising a service provided via the mobile communication network, an area, and a time during which the service is unauthorized in the area, wherein the base transceiver station transmits the data to a plurality of mobile handsets via the cell broadcast, and wherein the mobile handset is one of the plurality of mobile handsets;

receiving, by the mobile handset, from a user of the mobile handset at a current time, a request for the service;

determining, by the mobile handset, a location of the mobile handset;

determining, by the mobile handset, based on the data received via the cell broadcast, whether the service is unauthorized at the location of the mobile handset at the current time when the request for the service is received by the mobile handset from the user of the mobile handset; and

in response to the request for the service and to determining that the service is unauthorized at the location of the mobile handset at the current time when the request for the service is received by the mobile handset from the user of the mobile handset, blocking, by the mobile handset, the service.

9. The method of claim 8, wherein the location of the mobile handset is determined based on a local ability within the mobile handset.

10. The method of claim 8, further comprising allowing the service, even though the service is unauthorized at the location of the mobile handset at the current time, in response to the service being associated with an emergency.

11. The method of claim 8, wherein the service is associated with at least one of a streaming of audio, a streaming of video, or peer-to-peer communications.

12. The method of claim 11, wherein blocking the service comprises blocking the streaming of audio from the mobile handset.

13. The method of claim 11, wherein blocking the service comprises blocking the streaming of video from the mobile handset.

14. The method of claim 8, wherein the data received by the mobile handset via the cell broadcast is stored at the mobile handset in a first-in-first-out order.

15. A mobile handset that performs operations comprising:

receiving, from a base transceiver station of a mobile communication network via a cell broadcast, data comprising a service provided via the mobile communication network and an area within which the service is unauthorized, wherein the base transceiver station transmits the data to a plurality of mobile handsets via the cell broadcast, and wherein the mobile handset is one of the plurality of mobile handsets;

receiving, from a user of the mobile handset, a request for the service;

determining a location of the mobile handset;

determining, based on the data received via the cell broadcast, that the location of the mobile handset is within the area within which the service is unauthorized; and

in response to determining that the location of the mobile handset is within the area within which the service is unauthorized, blocking the service.

16. The mobile handset of claim 15, wherein the location of the mobile handset is determined based on a local ability within the mobile handset.

17. The mobile handset of claim 15, wherein the service is associated with at least one of a streaming of audio, a streaming of video, or peer-to-peer communications.

18. The mobile handset of claim 17, wherein blocking the service comprises blocking the streaming of audio from the mobile handset.

19. The mobile handset of claim 17, wherein blocking the service comprises blocking the streaming of video from the mobile handset.

20. The mobile handset of claim 15, wherein the operations further comprise allowing the service, even though the location of the mobile handset is within the area within which the service is unauthorized, in response to the service being associated with an emergency.
