Claim:
A method for sending messages from a base station to a mobile device, the method comprising: sending, by the base station, a first plurality of overhead messages to the mobile device in a wireless fashion, wherein the first plurality of overhead messages are sent according to a first periodic schedule with a first frequency, and wherein at least one of the first plurality of overhead messages comprises at least one parameter; sending, by the base station, a second plurality of messages to the mobile device in a wireless fashion, wherein said sending the second plurality of messages is performed according to a second periodic schedule with a second frequency, and wherein the second periodic schedule is based on the at least one parameter, and wherein the second frequency is less than the first frequency; and scheduling, by the mobile device, a sleep cycle based on the at least one parameter, thereby reducing battery consumption, wherein the sleep cycle is related to system time and a period parameter included in the at least one parameter, and wherein the sleep cycle is determined as T mod (APM_Period)=0 and APM_Period=2 APM — PeriodIndex ×16, and wherein T is time in units of the system time, and wherein the period parameter is “APM_PeriodIndex.”
