ABSTRACT:
Initiation of a hard handoff at a mobile station from an overlay carrier to an underlying carrier in a wireless telecommunications system may be considered based on a first condition being satisfied. Once the first condition is satisfied, hard handoff may be initiated based on at least one of a plurality of further conditions being satisfied. Advantageously, the plurality of further conditions may be arranged to be independent of the total power received at the mobile station and, therefore, independent of loading.
