Limiting services based on location

摘要

A system for authorizing services in wireless devices based on a type of service requested and a location of the wireless device. 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.

主权项

1. A method comprising:
receiving, by a subsystem of a wireless network, a request for a service in connection with two separate wireless devices using the wireless network and based upon locations of the two separate wireless devices, the request being received from a first wireless device and pertaining to a second wireless device that is distinct from the first wireless device; comparing, by the subsystem of the wireless network a location of the first wireless device and a location of the second wireless device to location data stored within a database of the wireless network, the location data including a geographic location at which the service is not authorized; determining, by the subsystem of the wireless network, whether a current time matches a predetermined time of restriction; determining, by the subsystem of the wireless network, whether the service relates to a first type of communication; determining, by the subsystem of the wireless network, based on a result of the comparing whether the service pertaining to the first wireless device and the second wireless device is authorized, wherein the service is authorized if the results indicate that both the first wireless device and the second wireless device are not located at the geographic location at which the service is not authorized; in response to determining that the service is authorized, provisioning, by the subsystem of the wireless network, the service in connection with the two separate wireless devices; and in response to determining that the service is not authorized,
blocking, by the subsystem of the wireless network, access to the service if it is determined that the service relates to the first type of communication, there is a restriction on the service at the current location, and the current time matches the predetermined time, andsending, by the subsystem of the wireless network, a text message to the first wireless device, the text message indicating:
that the service is not authorized at the geographic location,that the service is not authorized for the type of communication, andthat the service is not authorized for the current time.
