The present invention provides an enhanced method for initiating the selection of frames arriving from multiple base stations in a mobile communications system during a soft handoff condition. The method includes the steps of determining a number of base stations in an active set; receiving and storing a plurality of frames from those base stations in the active set where each frame is associated with a frame sequence. The method further includes the step of initiating selection of one of a plurality of received frames of a sequence upon satisfaction of at least one of a plurality of selection criteria which are based upon the active set and the received frames. Preferably, selection is performed immediately upon satisfaction of at least one selection criterion which includes: consecutively receiving all frames in a current sequence from the active set; receiving a frame from a sequence having a sequence number greater than a sequence number of a previously selected frame by a predetermined value; and consecutively receiving all frames in a delayed sequence from the active set prior to receiving all frames in a current sequence from the base stations.

[ What is claimed is:] [1.]1. A method for use in a base station controller of a mobile communications system for initiating the selection of one of a plurality of received frames during a handoff state comprising the steps of:determining a number of base stations in an active set;receiving and storing a plurality of frames from said base stations in said active set, each said frame being associated with a first sequence; andinitiating a selection of one of the plurality of received frames associated with the first sequence, said selection being initiated upon satisfaction of one of a number of selection initiating criteria, each selection initiating criteria being a function of the order of receipt of the plurality of frames associated with the first sequence.
