Method and apparatus for machine-to-machine communication registration

摘要

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.

主权项

1. A method for use in a wireless transmit/receive unit (WTRU) which is configured for machine type communications (MTC), comprising:
determining a designation of the WTRU in response to an event, wherein the WTRU belongs to a group; performing registration with a MTC server for all members of the group on a condition that the WTRU is a designated WTRU; obtaining connectivity information; uploading data to the MTC server; upon the WTRU being a last WTRU in the group that transmits information, performing one of:
releasing radio resources and Internet Protocol (IP) addresses and maintaining registration or releasing radio resources and maintaining IP addresses and registration; andentering a sleep cycle; entering a wake up cycle from the sleep cycle in response to the event; and listening for system updates from one of a control channel, a broadcast channel and a multicast channel, wherein the WTRU does not have to re-register.
