Anonymous positioning of a wireless unit for data network location-based services
View Patent ↗This invention concerns a process and a system for providing location information for a wireless unit in a wireless network to a location-based service provider, using a data network. In particular, the location information is provided to the location-based service provider without necessarily providing the identity of wireless unit, e.g., a subscriber's wireless identification number, to the service provider. In this regard, a subscriber's identification number may be hidden from the positioning service provider via a process in which an alias is used instead of the subscriber's normal identity. The subscriber's number may further be concealed from the service provider via a process wherein encrypted information is used instead of the subscriber's normal identity.
1. A method of providing location-based services to a wireless communications unit in a wireless communications network, comprising:
receiving a request for location-based services from the wireless communications unit, wherein the request includes an identifier of a location-based service provider and an identifier of the wireless communications unit within the wireless communications network;
determining location information of the wireless communications unit;
determining a unique identifier associated with the request based, at least in part, on the identifier of the wireless communications unit; and
using the location information and the unique identifier, without the identifier of the wireless communications unit, to provide location-based service information between the location-based service provider and the wireless communications unit via the wireless communications network.
2. The method of claim 1 , wherein the unique identifier is unique to the request.
3. A method of providing location-based services to a wireless communications unit in a wireless communications network comprising:
monitoring communications from the wireless communications unit over the wireless communications network to identify a service request to a location-based service provider; and
responsive to identification of the service request:
determining a unique identifier associated with the service request based, at least in part, on an identifier of the wireless communications unit in the wireless communications network; and
providing the unique identifier without the identifier of the wireless communications unit to the location-based service provider for use in providing location-based service information between the location-based service provider and the wireless communications unit.
4. The method of claim 3 , wherein the unique identifier is inserted into the service request to the location-based service provider.
5. The method of claim 3 , wherein the unique identifier is used to request location information for the wireless communications unit by the location-based service provider.
6. The method of claim 5 , wherein the unique identifier and requested location information for the wireless communications unit are used to provide location-based service information between the location-based service provider and the wireless communications unit via the wireless communications network.
