Abstract
A communication system (200) provides for a mobile station (MS) (202) to pre-register with a Serving GPRS Support Node (SGSN) (250) servicing a neighboring Routing Area (RA) (208) 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 MSs 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 the neighboring BSS. 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.
