Claim Text:
1. A method for operating a machine-to-machine device in a wireless network, comprising: switching a gateway between a first mode and a second mode according to a first time interval, to facilitate a machine-to-machine device to save power, wherein the gateway is connected between a first network and a second network and configured to periodically transmit, according to the first time interval, a message including information from the machine-to-machine device in the second network to a server in the first network; determining, by the gateway, a timing parameter for a machine-to-machine device based on the first time interval; and transmitting, by the gateway, a control signal including the timing parameter to the machine-to-machine device, the control signal causing the machine-to-machine device to adjust a second time interval for switching between the first mode and the second mode in accordance with the first time interval, wherein the adjusted second time interval is equal to the first time interval; wherein the timing parameter is determined by determining a target beacon transmission time (TBTT) based on a current time (currentTime) and a beacon interval (BI) as follows: T
