Patent ID: 8681701

Claim:
A mobile communications device for performing an enhanced access procedure, comprising: a wireless module, performing wireless transmissions and receptions to and from a cellular station of a service network; and a controller module, transmitting a random access preamble to the cellular station via the wireless module, receiving a random access response message corresponding to the random access preamble from the cellular station via the wireless module, transmitting a scheduled transmission message including machine type communication (MTC) data which is traffic data located in one or more MAC layer service data units to the cellular station via the wireless module, in response to the random access response message, and completing the enhanced access procedure in response to receiving a contention resolution message from the cellular station via the wireless module, wherein prior to the transmission of the scheduled transmission message, the controller module further determines whether the data size of the machine type communication data is less than or equal to a predetermined threshold value, wherein the step of transmitting the scheduled transmission message is performed in response to the data size of the machine type communication data being less than or equal to the predetermined threshold value.
