摘要

PPROBLEM TO BE SOLVED: To maintain a communication quality that is required for a class of communication performed before a handover, even after the handover in the handover between different wireless access systems. PSOLUTION: A handover control equipment 20 includes a handover destination determining unit 21, a handover controller 22, a radio resource use status collecting unit 23, and a system information database 24. The handover destination determining unit 21 is configured to determine a handover destination radio access system by determining whether communication quality of a communicating communication type used in a radio access system to which a mobile terminal 40 connects, can be provided by handover destination candidate radio access systems, and whether or not radio resources required for maintaining the communication quality of the communicating communication type can be secured.
