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

摘要

A radio terminal (10) includes an MIH user (14) configured to manage mobility from the first network to the second network; and an MIH function unit (13) configured to control a handover from the first network to the second network. The MIH user (14) notifies a link controller (12) via the MIH function unit (13) of a condition setting request including a first judgment logical formula being a condition to start an establishment of a radio link with the second network and a second judgment logical formula being a condition to execute a handover from the first network to the second network. The first judgment logical formula and the second judgment logical formula each indicate a combination of thresholds to be satisfied by a plurality of respective link is parameters in the radio link established with the first network.

1. A radio terminal configured to perform a handover from a first network to a second network employing a radio communication scheme different from that of the first network, the radio terminal comprising:
a first link controller configured to establish a radio link with the first network; a second link controller configured to establish a radio link with the second network; and a handover controller configured to control the handover from the first network to the second network, wherein the handover controller notifies the first link controller of a condition setting request including a plurality of first thresholds and a first logical formula to start an establishment of a radio link with the second network and a plurality of second thresholds and a second logical formula to execute a handover from the first network to the second network, the first logical formula comprising a combination of the first thresholds to be satisfied by a plurality of respective link parameters in the radio link established with the first network, wherein the first link controller uses the first logical formula to notify the handover controller when the link parameters in the radio link become worse than the first thresholds, and the second logical formula comprising a combination of the second thresholds to be satisfied by the plurality of respective link parameters in the radio link established with the first network, wherein the first link controller uses the second logical formula to notify the handover controller when the link parameters in the radio link become worse than the second thresholds.
