Communication Terminal, Access Point Switching Method, and Access Point Switching Control Program

摘要

[Subject] To realize optimum handover in consideration of not only reception environment of a communication terminal itself but also situations on the other party of communication. [Solving Means] A communication terminal includes: a reception environment information measuring unit for measuring information of reception environment around an access point; a transmission environment information measuring unit for measuring information of transmission environment around the access point; an access point search timing determining unit for determining a timing of searching for an access point to which the communication terminal is to be switched by using a combination of the measured reception environment information and transmission environment information; an access point searching unit for searching for an access point to which the communication terminal is to be switched at the access point search timing determined; a handover timing determining unit for determining a timing of handover to the access point to which the communication terminal is to be switched by using a combination of the measured reception environment information and transmission environment information; and a handover unit for performing handover to the searched access point at the determined handover timing.
