Wireless communication system, handover control device, wireless communication method, and handover control program

A handover control device for controlling a handover for switching a connection destination of a wireless terminal from a currently connected wireless communication station to a target wireless communication station, in response to the relative positional change of a plurality of wireless communication stations connected to a data network and the wireless terminal connected to said wireless communication stations to send and receive packets with the data network,

• said handover control device is configured to perform:
• receiving information relating to required QoS of service provided by the wireless terminal from said wireless terminal;
• determining priority of the handover for each wireless terminal based on the information related to the required QoS;
• and
• notifying said priority for each wireless terminal to the wireless communications stations in order to cause them to proceed with the handover for the plurality of wireless terminals for which a trigger of the handover has been occurred, according to said priority.

A wireless communication method for transmitting and receiving packets, via a plurality of wireless communication stations connected to a data network, between a wireless terminal located within a service area provided by the wireless communication station and the data network, including:

• switching a connection destination of the wireless terminal from the currently connected wireless communication station to a target wireless communication station as the relative position between the wireless terminal and the wireless communication stations changes;
• deciding a priority of the handover for each wireless terminal;
• and
• proceeding with the handover of a plurality of wireless terminals for which a trigger of the handover has been occurred, according to said priority.
