Abstract:
The invention relates to a method for tracking locations of mobile terminals in a communication network. Further, the invention relates to a communication network and apparatuses therein capable of performing individual steps of the method according to different embodiments of the invention. To decrease the signaling load imposed by mobility related signaling the invention suggests to group mobile terminals in so called mobility groups and to reduce the signaling overhead by performing a location update on a per-mobility group basis. In one exemplary embodiment of the invention this is realized by only one of the mobile terminals in a mobility group sending a group location update on behalf of the group to trigger the location update for the mobility group. Alternatively, in another embodiment of the invention, a network operator trusted or controlled entity sends a group location update on behalf of the group to trigger the location update for the mobility group.
