Methods and apparatus for easily and quickly returning to a first radio
access technology (RAT) network when handover to a second RAT network is
cancelled are provided. The methods and apparatus may involve a mobile
station (MS) entering idle mode before handover to the second RAT network
is completed and requesting a serving base station (BS) to retain MS
service and operational information, as well as service flow state
information. In this manner, should handover to the second RAT network be
cancelled before completion, a re-entry to the first RAT network may be
expeditiously performed using the retained MS information.
