Communication terminal, communication method and communication program

A communication method executed in a communication terminal,

• said communication terminal including;
• different kinds of communication portions;
• and
• a storage portion to store an address table in which target identification information for identifying a target to communicate and multiple pieces of access information respectively corresponding to said different kinds of communication portions are associated with each other,
• said communication method comprising the steps of:
• searching said address table, when a first communication portion of said different kinds of communication portions becomes incommunicable during communication with a communication target, and extracting access information which is related with said target identification information for identifying said communication target and corresponds to a second communication portion different from said first communication portion of said different kinds of communication portions;
• and
• transmitting a connection request to said communication target by said second communication portion using said extracted access information, wherein
• said address table further associates said target identification information with multiple pieces of address information respectively corresponding to said different kinds of communication portions for transmitting data,
• said extracting step includes the step of searching said address table and extracting address information which is related with said target identification information for identifying said communication target and corresponds to a second communication portion different from said first communication portion of said different kinds of communication portions, and
• said communication method further comprises the step of transmitting switching information indicating switching to said communication target by said second communication portion using said extracted address information before said connection request is transmitted.

A non-transitory computer-readable recording medium, storing thereon a communication program executed in a computer which controls a communication terminal,

• said communication terminal including:
• different kinds of communication portions;
• and
• a storage portion to store an address table in which target identification information for identifying a target to communicate and multiple pieces of access information respectively corresponding to said different kinds of communication portions are associated with each other,
• said communication program comprising the steps of:
• searching said address table, when a first communication portion of said different kinds of communication portions becomes incommunicable during communication with a communication target, and extracting access information which is related with said target identification information for identifying said communication target and corresponds to a second communication portion different from said first communication portion of said different kinds of communication portions;
• and
• transmitting a connection request to said communication target by said second communication portion using said extracted access information, wherein
• said address table further associates said target identification information with multiple pieces of address information respectively corresponding to said different kinds of communication portions for transmitting data,
• said extracting step includes the step of searching said address table and extracting address information which is related with said target identification information for identifying said communication target and corresponds to a second communication portion different from said first communication portion of said different kinds of communication portions, and
• said communication program further comprises the step of transmitting switching information indicating switching to said communication target by said second communication portion using said extracted address information before said connection request is transmitted.
