Description

  The present invention relates to a communication terminal device, a communication device control method, and a program.

  In recent years, in mobile communication terminal devices, communication terminal devices capable of communicating via different communication networks by one terminal device have become widespread. For example, there is a communication terminal device having both functions of a mobile phone function for performing communication by connecting to a mobile phone network and a communication function for performing communication by connecting to a public network via a wireless LAN. Such a communication terminal device has a telephone number used when communicating via a mobile phone network and a telephone number used when communicating via a public network via a wireless LAN. Select whether you are making or receiving calls.

When making a call to a communication terminal device capable of communication via such a plurality of communication networks, a caller user (hereinafter referred to as “calling terminal”) is a callee user (hereinafter referred to as “callee”). Any one of the plurality of telephone numbers held by the “side terminal”) is arbitrarily selected and transmitted.
At this time, if the called terminal does not exist in the serviceable area of the communication network corresponding to the telephone number selected by the calling terminal, communication between the calling terminal and the called terminal is not established. The terminal had to call again with another phone number.

Even if the calling terminal automatically performs a re-call with a different phone number to the called terminal, the judgment condition for executing the re-call is that the exchange cannot connect to the called terminal. Since it is a case where there is no response after a certain period of time after receiving the notification or after sending, it took a considerable amount of time.
Furthermore, the automatic re-calling operation of the calling terminal is such that after a call that has been ringing is released by making a call to the first selected telephone number, another telephone number is selected and the second call is made again. The processing load is heavy.
For this reason, there is a problem that it takes a considerable time and processing load to establish communication with the called terminal by the automatic re-transmission operation of the calling terminal.

In order to solve such a problem, when a transmission source user arbitrarily selects one telephone number and makes a call to a communication terminal having a telephone number corresponding to each of a plurality of types of communication networks, an appropriate communication network is selected. A technique (Patent Document 1) that uses and efficiently connects a call to a destination has been proposed.
Patent Document 1 discloses a communication network for determining a type of a communication network corresponding to a service area in which the destination terminal is located and using it as a connection destination for an incoming terminal (destination terminal) included in outgoing data. The technical contents of executing efficient call connection by selecting a telephone number corresponding to the communication network are described.

  However, the technique disclosed in Patent Document 1 converts an incoming call to a communication terminal device that has telephone numbers corresponding to a plurality of communication networks and can use these telephone numbers into an appropriate telephone number, and This is a technique for making an incoming call via an appropriate communication network, and a communication terminal device capable of communicating via a plurality of communication networks is not considered with respect to a telephone number and a communication network used when making a call.

For example, a communication terminal device having both functions of a mobile phone function for connecting to a mobile phone network and communicating with a public network, and a communication function for communicating as a terminal accommodated in a PBX via a wireless LAN However, even if it exists in an area where communication service via PBX is possible via a wireless LAN, there are cases where communication with the public network is performed by directly connecting to the mobile phone network by the selected call number.
That is, even when the communication terminal exists in an environment where an inexpensive communication service (communication via PBX via wireless LAN) can be used, depending on the telephone number of the destination selected by the user, expensive communication is possible. There is a problem that communication using a service (communication with a public network through a mobile phone network) is performed.

  The present invention has been made in order to solve the above-described problems, and in a communication terminal device capable of communication via a plurality of communication networks, the present invention is optimized based on information specifying a communication partner designated by a user.
