Abstract

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.

Claims

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; and

entering 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.

2. The method of claim 1, wherein performing registration performs an international mobile subscriber identity (IMSI) attachment procedure.

3. The method of claim 1, wherein the designated WTRU obtains radio resources and performs authorization and authentication, and wherein all group members use same radio resources.

4. The method of claim 1, wherein a designated WTRU is set by at least one of a network, randomly, hash algorithm or pre-configuration.

5. The method of claim 1, wherein a designated WTRU or the WTRU upon successful completion of registration by a designated WTRU, further comprises:

obtaining one of a group based packet-temporary mobile subscriber identity (P-TMSI) or a group based international mobile subscriber identity (IMSI);

obtaining an Internet Protocol (IP) address; and

obtaining user plane radio resource information.

6. The method of claim 1, further comprising:

performing MTC service registration using one of a uniform resource identity (URI) or a uniform resource locator (URL) on a condition that the WTRU is a designated WTRU or upon MTC server requirement; and

accessing the MTC server based on the URI or URL.

7. The method of claim 1, wherein the wake up cycle includes a control cycle and reporting cycle.

8. The method of claim 7, upon detection of a reporting cycle, further comprising:

obtaining radio resources for all members of the group on a condition that the WTRU is a designated WTRU;

obtaining user plane radio resource information;

performing MTC service registration using one of a uniform resource identity (URI) or a uniform resource locator (URL) upon MTC server requirement; and

accessing the MTC server based on the URI or URL.

9. The method of claim 8, further comprising:

obtaining an IP address on a condition that the WTRU is a designated WTRU.

10. The method of claim 8, further comprising:

upon the WTRU being the last WTRU, performing one of;

releasing radio resources and IP addresses and maintaining registration;

or

releasing radio resources and maintaining IP addresses and registration; and

entering the sleep cycle.

11. The method of claim 7, upon detection of a control cycle, further comprising:

re-entering the sleep cycle upon determining an absence of a paging message.

12. The method of claim 7, upon detection of a control cycle, further comprising:

designating the WTRU as a designated WTRU upon receipt of an individual page;

obtaining radio resources for all members of the group on a condition that the WTRU is a designated WTRU;

obtaining user plane radio resource information;

performing MTC service registration using one of a uniform resource identity (URI) or a uniform resource locator (URL) upon MTC server requirement; and

accessing the MTC server based on the URI or URL.

13. The method of claim 12, further comprising:

obtaining an IP address on a condition that the WTRU is a designated WTRU.

14. The method of claim 12, further comprising:

upon the WTRU being the last WTRU, performing one of;

releasing radio resources and IP addresses and maintaining registration;

or

releasing radio resources and maintaining IP addresses and registration; and

entering the sleep cycle.

15. The method of claim 7, further comprising:

waiting for a paging message including WTRU designation information.

16. The method of claim 8, wherein individual WTRUs allocate different local IP addresses for the duration of the reporting cycle.

17. The method of claim 12, wherein the WTRU is updated using a paging message with international mobile subscriber identity (IMSI)/packet-temporary mobile subscriber identity (P-TMSI) and account numbers.

18. A wireless transmit/receive unit (WTRU) for machine type communications (MTC), comprising:

a transmitter;

a receiver;

a processor in communication with the receiver and transmitter;

the processor configured to determine a designation of the WTRU in response to an event, wherein the WTRU belongs to a group;

the processor configured to perform registration with a MTC server for all members of the group on a condition that the WTRU is a designated WTRU;

the processor, transmitter and receiver configured to obtain connectivity information;

the transmitter configured to upload data to the MTC server;

upon the WTRU being a last WTRU in the group that transmits information, performing one of;

the processor, transmitter and receiver configured to release radio resources and Internet Protocol (IP) addresses and maintain registration or the processor, transmitter and receiver configured to release radio resources and maintain IP addresses and registration; and

the WTRU configured to enter a sleep cycle;

the WTRU configured to enter a wake up cycle from the sleep cycle in response to the event; and

the processor and receiver configured to listen 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.

19. The WTRU of claim 18, wherein the designated WTRU obtains radio resources and performs authorization and authentication, and wherein all group members use same radio resources.

20. The WTRU of claim 18, wherein a designated WTRU or the WTRU upon successful completion of registration by a designated WTRU, further comprises:

the processor, transmitter and receiver configured to obtain one of a group based packet-temporary mobile subscriber identity (P-TMSI) or a group based international mobile subscriber identity (IMSI);

the processor, transmitter and receiver configured to obtain an Internet Protocol (IP) address; and

the processor, transmitter and receiver configured to obtain user plane radio resource information.
