Abstract:
1. A method for paging an idle Mobile Station (MS), comprising: sending a Paging Announce message to a Base Station (BS) in a Paging Group (PG) containing the MS, and starting a timer; responding, by the BS, to the Paging Announce message, and paging the MS; and stopping paging to the MS when no paging response is received from the MS upon expiry of the timer; wherein a relay paging controller (PC) sends the Paging Announce message to the BS in the PG according to the Paging Announce message of an anchor PC and the PG information of the MS: wherein the relay PC is the relay PC that performs the last location update of the MS, or a relay PC adjacent to the relay PC performing the last location update of the MS; wherein the BS sends a paging response to the anchor PC and/or the correlated relay PC upon paging the MS successfully before expiry of any timer; wherein the BS sends a paging response or a message indicative of paging success to the anchor PC and/or the correlated relay PC, after the BS pages the MS successfully; and wherein the relay PC directly instructs a Paging Agent (PA) in the corresponding PG under the relay PC to stop paging, and instructs other correlated relay PCs to stop paging from the BS in the correlated relay PCs to the MS.
