Abstract
A computer-readable medium, device and system for responding to a request for a geographically-based service are provided. A request for a geographically-based service is received. The received request indicates that a geographical position of a target node and a radius associated with a maximum distance from the geographical position is requested. A requesting service message is formatted that is associated with a higher-layer protocol and includes an indicator indicating that the geographical position of the target node and the radius is requested. The requesting service message is merged in a first header of a requesting datagram which is sent to the target node. A reply datagram is received from the target node and a reply position message component is extracted from the received reply datagram. A reply position message component is extracted from a second header of the received reply datagram. The first geographical position of the target node and the radius from the extracted reply position message component is determined. A response to the received request is provided based on the determined radius and the determined geographical position.
