Abstract: A base station is configured to wirelessly communicate with a mobile station. The base station has a communication device configured to receive a message including at least one information element, before establishment of a Radio Resource Control (RRC) connection is completed. The base station has a processor configured to acquire ability information relating to the ability of the mobile station, on the basis of the at least one information element.

Abstract: A communications processing device that reduces the time after call disconnection until call reconnection, by using a message having a higher delivery probability than a handover instruction, when wireless quality could result in handover instruction failure. The communications processing device includes: a measurement report acquisition unit that obtains a measurement report relating to a communications environment from a mobile communications terminal located within the cell; a wireless quality determination unit that determines whether or not the quality of wireless communications with the mobile communications terminal, included in the measurement report, is lower than a threshold value; and a message transmission unit that, if the wireless quality is less than the threshold value, sends to the mobile communications terminal a message that has less data volume than a handover instruction message and includes the carrier frequency for the base station to be handed over.
