1. A method, comprising:
- receiving a ranging request message 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, and wherein the mobile node is in a sleep mode;
identifying an originating base station that previously served the mobile node by determining a base station identifier (BSID) associated with the originating base station from the ranging request message;
retrieving an original service context associated with the mobile node, the original service context comprising at least one of a class of traffic or a quality of service associated with a connection maintained by the WPSN on behalf of the mobile node; and
responding to the ranging request message with a ranging response message;
wherein the original service context is retrieved by the destination base station from the originating base station based on the destination base station contacting 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.

9. An apparatus, comprising:
-
logic associated with a destination base station in a wireless packet-switched network (WPSN) to receive a ranging request with a sleep-mode indication from a mobile node, wherein no service context associated with the mobile node exists at the destination base station, and wherein the mobile node is in a sleep mode; logic to identify an originating base station that previously served the mobile node by determining a base station identifier (BSID) associated with the originating base station from the ranging request; logic associated with the destination base station to contact the originating base station and retrieve a service context associated with the mobile node from the originating base station, the service context comprising at least one of a class of traffic or a quality of service associated with a connection maintained by the WPSN on behalf of the mobile node; and logic to respond to the ranging request with a ranging response, the ranging response sent to the mobile device. - View Dependent Claims (10, 11, 12)
