Abstract  Abstract

The invention relates to method and apparatus for mobile assisted hard handoff between communication systems of. specifically claims a for method and apparatus for performing hard handover between systems or for inter-frequency hard handover in a CDMA system between a communication system (S1 S2). The purpose of the invention is to reduce the probability of dropped calls when the system hard handoff. in the effort of hard handover failure situation the mobile station (18) sends the communication system of the invention uses information back to the original system (S1) to assist the switching carried out. or not intended to switch the mobile station (18) monitors the destination system (S2) then carries information for use in a subsequent handoff attempts return to the original system (S1). The information returned from monitoring a CDMA system of comprises searching one or more pilot result (these pilots given at offsets in a specific list provided to the mobile station (18) by the base station (B1-B5) or a set of offsets based upon a predetermined search algorithm.
