<p>The invention provides a method and arrangement for locating a cellular mobile station in a cellular mobile network. A terminal-based location arrangement in the cellular mobile network for locating and tracking the cellular mobile station is applied. The cellular mobile station(s) independently stores cellular network location information in a time dependent manner depending on a certain criteria for updating the location information. A timestamp indicating a point of time for current cellular network location information can be applied. The criteria for storing the location information and the timestamp can be that the cellular mobile station moves to another cell. The location information stored in the cellular mobile station can be transmitted to the location-based services. The transmission can be based on triggering being based on location criteria or a point-to-point request messaging. Broadcast messaging can be applied for the triggering for delivering the location criteria to the cellular mobile station. The location criteria establish a target route, and traveling the route triggers the transmission of the location information.</p> |
