Apparatus, method and computer program product providing optimized location update for mobile station in a relay-based network

摘要

A relay node receives individual ones of a plurality of request messages destined for a network access node from individual ones of a plurality of user nodes; aggregates the received individual ones of the plurality of request messages into a single message at the relay node; and sends the single message to the network access node. The relay node further operates to receive from the network access node a single message that contains an aggregated plurality of response messages for individual ones of the user nodes and sends individual ones of the response messages to individual ones of the user nodes. The method advantageously handles the case of a mobile relay node, having a plurality of attached idle state mobile stations/subscriber stations, that transitions to a new paging group.
