1. A method, including:
- receiving a ranging request message with a sleep-mode indication from a mobile node at a destination base station in a wireless packet-switched network (WPSN), wherein no service context associated with the mobile node exists at the destination base station at a time of receiving the ranging request message;
determining a base station identifier (BSID) associated with an originating base station from system paging information, wherein the originating base station last served the mobile node; and
contacting the originating base station to retrieve a service context associated with the mobile node and to retrieve any downlink packets buffered for the mobile node by the originating base station.

Abstract
Embodiments herein may receive a ranging request message with a sleep-mode indication from a mobile node at a destination base station in a wireless packet-switched network. System paging information may be accessed to determine a base station identifier associated with an originating base station that last served the mobile node. The originating base station may be contacted to retrieve a service context associated with the mobile node and any downlink packets buffered for the mobile node by the originating base station. Other embodiments may be described and claimed.
