Group-based machine to machine communication
First Claim
1. A method for performing group-based machine-to-machine communication, the method comprising:
- waking up from a sleep cycle;
listening for at least one of paging or broadcast from a communication network;
receiving an indication from the communication network via the at least one of paging or broadcast, the indication comprising information associated with an IP address, wherein the IP address is allocated for a machine type communication (MTC) group comprising a plurality of MTC wireless transmit/receive units (WTRUs), wherein the IP address is allocated prior to a MTC WTRU network registration process associated with the MTC group;
obtaining the IP address based on the received indication;
sending data using the obtained IP address in a prescribed transmission window; and
returning to the sleep cycle upon the MTC WTRUs completing data transmission.

Abstract
Methods and apparatus are provided for performing group-based machine-to-machine communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in MTC groups. MTC WTRUs belonging to the same MTC group may use a group-based International Mobile Subscriber Identity (IMSI) and a group-based IP address for data transmission. Group-based network registration may be performed. A group-based IP address and radio resources may be proactively allocated for an MTC group. A master MTC may perform network registration/attachment process on behalf of the MTC group. A group of MTC WTRUs may transmit data according to staggered time windows.

17. A wireless transmit and receive unit (WTRU) configured to perform group-based machine-to-machine communication, the WTRU comprising:
a processor configured to; wake up from a sleep cycle; listen for at least one of paging or broadcast from a communication network; receive an indication from the communication network via the at least one of paging or broadcast, the indication comprising information associated with an IP address, wherein the IP address is allocated for a machine type communication (MTC) group prior to a MTC WTRU network registration process associated with the MTC group, the MTC group comprising a plurality of MTC WTRUs; obtain the IP address based on the received indication; determine a prescribed transmission window associated with the WTRU for transmitting data; send data using the allocated IP address in the prescribed transmission window; and return to the sleep cycle upon the MTC WTRUs completing data transmission. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
