There is provided a device, comprising a positioner configured to determine, at least in part, a position of the device and a request processor for processing and selectively responding to requests for information regarding the position of the device. The positioner comprises a GPS receiver used to calculate the position of the device. A communications network in which the device operates may finally calculate the position. Further, the device may be configured to automatically respond to certain network management location information requests, which are generated by a communications network in which the device operates. The device may also be configured to automatically respond to information requests that result from an emergency communication initiated by the user or that originate from certain specified agencies. Alternatively, the device may be programmed to respond to certain request types depending on input from the user of the device. The request types may be related to services and events that are based on the location of the device or that are based on input from the user.
