Radio terminal, information processing device, information processing program, and information processing method

An information processing device comprising:

• at least one processor that comprises:
• a mobility manager configured to manage mobility from a first network to a second network employing a radio communication scheme different from that of the first network;
• and
• a handover controller configured to control a handover from the first network to the second network, wherein
• the mobility manager, which is a layer above the handover controller, notifies the handover controller of a threshold setting request for requesting a set-up of a threshold for a link parameter to be monitored in a first radio link established with the first network,
• in response to the threshold setting request, the handover controller notifies a first link controller configured to establish the first radio link with the first network, of a condition setting request including a first condition being a condition to start an establishment of a second radio link with the second network and a second condition being a condition to execute the handover from the first network to the second network,
• the first condition indicates a first combination of thresholds to be satisfied by a plurality of link parameters in the first radio link established with the first network,
• the second condition indicates a second combination of thresholds to be satisfied by the plurality of link parameters in the first radio link established with the first network, and
• the first link controller notifies the handover controller of information including an operation type when the first or second combination of thresholds is satisfied by a plurality of link parameters in the first radio link.

An information processor configured to be used in an information processing apparatus provided with a mobility manager configured to manage mobility from a first network to a second network employing a radio communication scheme different from that of the first network, and a handover controller configured to control a handover from the first network to the second network, wherein the processor is configured to execute the steps of:

• notifying, from the mobility manager, which is a layer above the handover controller, to the handover controller, a threshold setting request for requesting a set-up of a threshold for a link parameter to be monitored in a first radio link established with the first network;
• and
• notifying, from the handover controller to a first link controller configured to establish the first radio link with the first network, a condition setting request including a first condition being a condition to start an establishment of a second radio link with the second network and a second condition being a condition to execute the handover from the first network to the second network, in response to the threshold setting request, wherein
• the first condition indicates a first combination of thresholds to be satisfied by a plurality of link parameters in the first radio link established with the first network,
• the second condition indicates a second combination of thresholds to be satisfied by the plurality of link parameters in the first radio link established with the first network, and
• notifying the handover controller of information that includes an operation type when the first or second combination of thresholds is satisfied by a plurality of link parameters in the first radio link.

An information processing method used in an information processing device provided with an MIH user configured to manage mobility from a first network to a second network employing a radio communication scheme different from that of the first network, and an MIH function unit configured to control a handover from the first network to the second network, the information processing method comprising the steps of:

• notifying, from the MIH user, which is a layer above the MIH function unit, to the MIH function unit, a MIH_Configure.request for requesting a set-up of a threshold for a link parameter to be monitored in a first radio link established with the first network;
• and
• notifying, from the MIH function unit to a first link controller configured to establish the first radio link with the first network, a Link_Configure_Threshold.request including a first condition being a condition to start an establishment of a second radio link with the second network and a second condition being a condition to execute the handover from the first network to the second network, in response to the MIH_Configure.request, wherein
• the first condition indicates a first combination of thresholds to be satisfied by a plurality of link parameters in the first radio link established with the first network,
• the second condition indicates a second combination of thresholds to be satisfied by the plurality of link parameters in the first radio link established with the first network, and
• notifying the MIH function unit of information that includes an operation type when the first or second combination of thresholds is satisfied by a plurality of link parameters in the first radio link.
