NAS-BASED SIGNALING PROTOCOL FOR OVERLOAD PROTECTION OF RANDOM ACCESS IN MASSIVE MACHINE TYPE COMMUNICATION

摘要

A scheme of minimizing the random access load on the network to support MTC or M2M devices is provided. In particular, the concept of grouping (e.g., collecting, combining, aggregating, etc.) MTC or M2M devices based on non-access stratus (NAS) signaling is performed. Doing so results in reduced the random access load on the network such that a large number of MTC or M2M devices can be accommodated.
