Method and system of transmitting packet data units of machine type communication devices over a network interface in a long term evolution network

摘要

The present invention provides a method and apparatus for transmitting packet data units (PDUs) associated with machine type communication (MTC) devices over a network interface in a long term evolution network. In one embodiment, PDUs associated with one or more MTC devices are aggregated for a time period by a first network entity. Then, the aggregated PDUs associated with the one or more MTC devices are concatenated into a GTP packet data unit, where a GTU header of the GTP packet data unit indicates aggregated PDU indication, a number of aggregated PDUs, and a length of each of the aggregated PDUs. The GTP PDU includingthe aggregated PDUs is transmitted to a second network entity over a single S1-U/S-5 bearer via a S1-U/S5 interface that connects the first network entity and the second network entity.
