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.
