Research and Realization of Bearer Control Entity BC of UE Side in LTE System

Article Preview

Abstract:

In LTE system, control plan and user plan are separated. Therefore ESM sub-layer which belongs to control plan can neither manage the using of physical bearers real time, nor implement the function of up-link traffic flow template UL-TFT. In order to transferring users data correctly and obtaining corresponding QoS service, it is necessary to add a bearer control entity BC in user plan during designing of protocol stack in UE, which can manage bearers and identify service data flows-SDF.
