Abstract
Location information is generated for a mobile device using a global positioning system (GPS) receiver (17) or by other means. A request for receipt of location information is received at the mobile device, over a wireless communications channel from a requesting entity (25), and a confirmation of permission to receive location information is sent to the requesting entity, over the wireless communication channel. The confirmation includes a digital signature for the requesting entity to use as verifiable proof of confirmation of permission. The requesting entity can use the digital signature to obtain the location information from a location server (21). The requesting entity and/or the location server are optionally located in the mobile communications device.
