ABSTRACT:
A method, a computer program product and a network access node that operate to receive a message from a mobile relay node, the message including a request to add a particular paging group (PG) identification to a list of paging group identifications transmitted by the network access node; to contact a network backbone node to request permission to add the particular paging group identification to the list of paging group identifications transmitted by the network access node; and upon being granted permission, to add the particular paging group identification to the list of paging group identifications transmitted by the network node. The exemplary embodiments of this invention pertain also to the relay node and to the network backbone node. Through the use of the exemplary embodiments idle state user nodes that are attached to the mobile relay node do not see a change in the PG, since the particular PG is maintained by the mobile relay node and, therefore, the user nodes do not initiate a Location Update (LU) procedure when the relay node enters a new PG. Instead, only the mobile relay node performs the LU procedure with the network access node.
