Abstract:
A cellular telecommunication system for providing Mobile Assisted Hard Handoff (MAHHO) between base stations using different frequencies comprising:a plurality of base stations, each transmitting and receiving on forward and reverse transmission links, respectively, each base station using different forward link carrier and reverse link carrier frequencies;at least one mobile station for communicating with a first base station using a first forward link carrier frequency and a first reverse link carrier frequency, and for communicating with at least a second base station using a second forward link carrier frequency and a second reverse link carrier frequency different from said first forward carrier link frequency and first reverse carrier link frequency used by said first base station,said at least one mobile cellular station, each further including a MAHHO apparatus comprising means for performing handoff measurements on forward link transmissions of said at least second base station on said second forward link carrier frequency thereof, said measurements of said forward link transmissions of said at least second base station being performed by said MAHHO apparatus by puncturing data to be transmitted during selected transmission periods on said first reverse link carrier frequency to said first base station.
