Data processing methods for processing machine type communication data and wireless communications systems thereof

A wireless communication system, comprising:

• a plurality of terminals, for sending a plurality of machine type communication data flows;
• an intermediate device, coupled to the plurality of devices, for receiving the plurality of machine type communication data flows via a first interface, performing a data multiplexing operation on the plurality of machine type communication data flows to generate a multiplexed data flow;
• and
• a service network coupled to the intermediate device for receiving the multiplexed data flow,
• wherein the intermediate device comprises a gateway combined with one of the following or the combination thereof:
• a relay node and a home Node-B, wherein the data multiplexing operation is performed by a data multiplexing layer, the data multiplexing layer being integrated in the one of the following or the combination thereof:
• the relay node and the home Node-B, wherein the data multiplexing operation comprises a protocol translation of the machine type communication data flows from a first radio access technology to a second radio access technology, and wherein the converted machine type communication data flows are output via a second interface of the intermediate device.
