  • Mobility management method for delivering calls in a microcellular network
    Patent number: 5521961
    Abstract: In a method of providing cellular telephone service to a mobile telephone located in an off-load cellular telephone system adjacent to a main cellular telephone system, the mobile telephone is registered with the off-load cellular telephone system upon the mobile telephone entering the off-load cellular telephone system, and then is registered with the main cellular telephone system as being located in the off-load cellular telephone system as a function of predetermined criteria. During the time in which the mobile telephone has entered the off-load cellular telephone system but has not yet registered with the main cellular telephone system as being located in the off-load cellular telephone system, rebroadcasting page signals from main cellular telephone system into the off-load cellular telephone system ensures delivery of incoming telephone calls to the mobile telephone.
