US 2017/0289876 A1 · Device and Method of Handling Handover

Abstract

A first base station (BS) for handling a handover with a second BS comprises a storage unit for storing instructions and a processing circuit coupled to the storage unit. The processing circuit is configured to execute the instructions stored in the storage unit. The instructions comprise determining to hand over a first communication device to the second BS; generating a first handover request message, wherein the first handover request message comprises one of first system information and second system information according to whether the first communication device is in coverage enhancement (CE) or according to a type of the first communication device; transmitting the first handover request message to the second BS; receiving a first handover request acknowledgement message from the second BS; and transmitting a first handover command to the first communication device in response to the reception of the first handover request acknowledgement message.

a storage unit, for storing instructions of:
connecting to the first BS;
receiving a handover request message for a first communication device from the first BS;
generating a handover request acknowledgement message in response to the handover request message;
generating a first configuration according to first system information and transmitting the handover request acknowledgement message comprising the first configuration to the first BS, if the handover request message comprises the first system information and the first communication device is in coverage enhancement (CE) or a type of the first communication device is a first type;
and
generating a second configuration according to second system information and transmitting the handover request acknowledgement message comprising the second configuration to the first BS, if the handover request message comprises the second system information and the first communication device is in not CE or the type of the first communication device is a second type;
and
a processing circuit, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
