Patent ID: 8060089

Claim:
A method for handling registration requests in a cellular wireless communication system, the method comprising: the cellular wireless communication system making a first determination that a transmission-success rate of messages sent via a forward link of an air interface in the cellular wireless communication system is less than a threshold success rate; the cellular wireless communication system making a second determination that the air interface has less than a threshold level of load, at least in part by determining (i) that access channel time slot occupancy percentage on a reverse link of the air interface is lower than a threshold access channel time slot occupancy percentage and (ii) that paging channel time slot occupancy percentage on the forward link of the air interface is lower than a threshold paging channel time slot occupancy percentage; and responsive to the first determination and second determination, the cellular wireless communication system increasing a frequency at which mobile stations register with the cellular wireless communication system via the air interface, wherein increasing the frequency at which mobile stations register with the cellular wireless communication system via the air interface comprises decreasing a registration period in a registration-period directive to the mobile stations.
