A first BS for handling the eLTE network for a communication device comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise receiving a radio resource control (RRC) Connection Request message; transmitting a RRC Connection Setup message; receiving a RRC Connection Setup Complete message; receiving a UE-EUTRA-Capability information element (IE); transmitting a radio bearer (RB) configuration configuring a data radio bearer (DRB); communicating at least one packet data convergence protocol (PDCP) service data unit (SDU) of the DRB with the communication device; determining to initiate a handover for the communication device to a second BS; transmitting a Handover Request message to the second BS; receiving a Handover Request Acknowledge message from the second BS; and transmitting the Handover Command message to the communication device.
