1. A mobile communications device for performing a buffer status reporting procedure, comprising:
- a wireless module, performing wireless transmissions and receptions to and from a cellular station of a service network; and
a controller module, receiving machine type communication (MTC) data, and determining whether to trigger a buffer status report (BSR) to the cellular station via the wireless module according to a comparison result of the data size of the MTC data and a threshold value when the MTC data arrives at an empty transmission buffer of the mobile communications device,wherein the controller module further determines whether to trigger the BSR according to a comparison result of the data size of the MTC data and an accumulated data size of the transmission buffer and the threshold value when the MTC data arrives at an empty transmission buffer of the mobile communications device, wherein the controller module triggers the BSR when a total amount of the data size of the MTC data and the accumulated data size of the transmission buffer is greater than the threshold value and the controller module further starts a timer when the data size of the MTC data is less than or equal to the threshold value, directs the timer to start a count when the total amount of the data size of the MTC data and the accumulated data size of the transmission buffer is less than or equal to the threshold value, and triggers the BSR when the count of the timer has expired.

Abstract
A mobile communications device with a wireless module and a controller module for performing a buffer status reporting procedure is provided. The wireless module performs wireless transmissions and receptions to and from a cellular station of a service network. The controller module receives machine type communication (MTC) data, determines whether to trigger a buffer status report (BSR) according to a comparison result of the data size of the MTC data and a threshold value when the MTC data arrives at an empty transmission buffer, and if so, transmits the BSR to the cellular station via the wireless module.
