Abstract:
1. A last hop router configured for use in a telecommunication system, the last hop router comprising: a paging area clustering agent to receive movement reports from mobile hosts in the telecommunication system, to determine dynamic clustering of paging areas based upon statistical mobility information derived from the movement reports, and to send paging messages to local paging agent clusters to page a mobile host; a dormant monitoring agent to detect delivery of packets addressed to a mobile host in dormant mode and activate the paging area clustering agent to send a paging message to the local paging agent clusters to page the mobile host; and a local paging agent for sending paging signals to mobile hosts identifying a paging area associated with the last hop router, wherein the paging area clustering agent performs the following processes: a probability map update process, wherein the probability map update process receives a registration signal from a mobile host, calculates statistics of mobile host movement and updates the probability map, and determines frequencies of mobile host movements and notifies the clustering process; a clustering process, wherein the clustering process locates and determines paging areas to be joined or disjoined from other paging areas and updates the cluster maps of the paging area and other paging areas; and a paging forwarding process, wherein the paging forward process receives a paging trigger packet from the dormant monitoring agent and queries the cluster map to determine to which area a packet should be delivered, forwards the paging trigger packet to the area, and notifies the clustering process of frequencies of paging trigger packets received.
