Methods and apparatus are disclosed for Machine to Machine (M2M) communication registration. The methods provide single and periodic registration and may be device or network based. The devices in the system may be divided into groups. A single device member may perform the basic access steps for the group. Other devices may receive related access information on a control channel and use the information to access the system. The devices may send data, get updates, and then go to sleep. Internet addresses may be released or maintained. During a control cycle, the devices may wake up and listen to the control channel for any paging messages. Individual devices or the entire group may access the system. During a reporting cycle, all the devices may wake up and access the system to connect to the M2M system to upload data.
