ACCESS CONTROL AND CONGESTION CONTROL IN MACHINE-TO-MACHINE COMMUNICATION

摘要

Performing load balancing by a wireless transmit/receive unit, WTRU, includes evaluating by the WTRU autonomously a current cell load value and, on a condition that the current cell load value is greater than a predetermined threshold, performing load balancing by barring the current cell (i.e. by adding the current cell to a barred cell list for a predetermined period of time). The current cell load value may be the number of consecutive failed RACH access attempts. Other embodiments teach a method to identify a machine type communication, MTC, device, a method to restrict access to a group (set) of MTC devices, a method to restrict access to a particular MTC device, a method to control congestion, and a method for MTC device prioritization.
