Method and apparatus for mobile station registration in a cellular communication system
First Claim
1. A method for registering a mobile station comprising:
- registering the mobile station with a first Serving GPRS Support Node (SGSN), wherein the first SGSN services a first Base Station System (BSS) that provides communication services to the mobile station;
assembling a Neighbor List that comprises a plurality of communication channels, wherein a communication channel of the plurality of communication channels is associated with a second BSS that is serviced by a second SGSN that is different than the first SGSN; and
at least partially registering the mobile station with the second SGSN prior to the mobile station being served by the second BSS.

Abstract
A communication system provides for a mobile station (MS) to pre-register with a Serving GPRS Support Node (SGSN) servicing a neighboring Routing Area (RA) that is a handoff candidate. In pre-registering with the neighboring RA and SGSN, the MS at least partially registers with the RA and SGSN, that is, at least a portion of the MS'"'"'s registration information is conveyed to the neighboring SGSN serving the neighboring RA, prior to the MS being served by an associated neighboring BSS 230, for example, prior to an initiation of a handoff of the MS to neighboring BSS 230. By pre-registering with the candidate SGSN, a duration of a registration process and the corresponding service disruptions when the MS is handed off to such an SGSN are reduced.

40. A mobile station comprising:
-
at least one memory device; and
a processor operably coupled to the memory device that receives a Neighbor List comprising a plurality of communication channels, stores the Neighbor List in the at least one memory device, and conveys to an infrastructure a request to pre-register the mobile station in a Routing Area associated with a communication channel of the plurality of communication channels prior to the mobile station being served by a Base Station System associated with the communication channel of the plurality of communication channels. - View Dependent Claims (41, 42, 43, 44, 45)
