Wireless communication terminal, wireless communication network system and handover timing determining method
Abstract:
A wireless communication terminal includes a first detecting section for detecting whether or not a reception signal level indicating a level of a received signal from a base station currently in connection as the first base station reduces to be equal to or lower than a first threshold level, a second detecting section for detecting whether or not a communication situation of a communication application program currently in communication is a situation suitable for handover, a third detecting section for detecting whether or not a predetermined handover forcedly performing condition is established, a determining section for determining whether or not the handover control is necessary, based on detection results of the first to third detecting section, and a communication control section for performing a handover control to switch from the first base station to a second base station when the switching to the handover control is necessary.
