Abstract

PROBLEM TO BE SOLVED: To decide whether a call tariff for a currently used line is expensive or not by having a radio part for every radio carrier, having a different incoming call sound in accordance with a kind of this received radio carrier ring when a calling from another party terminal is received and displaying this kind at a display part. SOLUTION: When communication is performed through one of radio parts 1 to n from another party terminal, display or an incoming call of a radio carrier the other party terminal uses is made to ring. On the basis of the incoming call sound, the receiver is picked up and responded. When responded, a buzzer sound for deciding the kind of the radio carrier the other party terminal uses is made to ring. On the other hand, when transmission is performed from a reception terminal to the other terminal, the radio carrier being used is displayed and, at the same time, a transmission sound is made to ring. When the other terminal picks up the receiver and responds on the basis of the transmission sound, the kind of the currently used radio carrier is informed to the other terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication terminal device capable of notifying a user and a communication partner of the types of a plurality of radio carriers in use.

[0002]

2. Description of the Related Art Conventionally, in a wired telephone network, telephones equipped with an LCR function for automatically selecting a low-cost communication carrier have become widespread. This is an effective function because a single telephone can use a communication line of a communication carrier having different call rates. On the other hand, advances in mobile communication related technologies have made it possible for a single mobile communication terminal device to select and use wireless lines provided by a plurality of wireless communication carriers. In addition, PHS is required between wireless communication carriers.
There are cases where charges differ significantly, such as mobile phones. Unlike the case of wired communication, a portable communication terminal using wireless communication may use a wireless carrier having a higher call fee because there are areas where communication is possible and areas where communication is not possible. In particular, in the case of an incoming call, it is not possible for the user of the portable communication terminal device to select a wireless carrier and make a call.

[0003]

As described above, in a conventional portable communication terminal device, for example, when a combined communication terminal device of a portable telephone and a PHS is considered, a portable telephone generally having a high call charge is considered. It is economical to make carrier calls simple. On the other hand, when a service for transferring a call from a general telephone to a mobile phone is considered, an incoming call may be made to the mobile phone without recognizing that the other party uses the carrier of the mobile phone. Therefore,
Since there is no function to notify the user of the mobile terminal and the other party of the call at the time of receiving an incoming call or the start of a call, that the carrier being used is a mobile phone, a long-time call is made with a wireless carrier having a high call charge. Was.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and has a radio unit for each radio carrier, and can communicate with a desired radio carrier via this radio unit. A portable communication terminal device which, when receiving a call from a partner terminal, sounds a different ringtone according to the type of the received wireless carrier and displays the type on a display unit. Provide equipment.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a portable communication terminal device according to one embodiment of the present invention, FIG. 2 is a flowchart illustrating an incoming call operation of the portable communication terminal device according to one embodiment of the present invention, and FIG. 5 is a flowchart illustrating a calling operation of the mobile communication terminal device according to one embodiment of the present invention. In FIG. 1, 1 is a mobile communication terminal device, 2 is a man-machine I / F processing unit, 3 is a wireless carrier selection process,
Reference numeral 5 denotes a power supply processing unit. That is, the radio unit 1 of the portable communication terminal device 1 of the present invention corresponds to the radio carrier A, the radio unit 2 corresponds to the radio carrier B, and the radio unit n also corresponds to the radio carrier X, Furthermore, these radio units (1
To n) respectively correspond to the protocol processing units (1 to n).

The operation will be described with reference to FIGS. In FIG. 2, a wireless unit 1
When a call is made via one of the wireless units n, the display of the wireless carrier used by the partner terminal and the ringtone are sounded (S20). Then, based on the ring tone, the receiver is picked up and a response is made (S21). If a response is made, a buzzer sound is sounded for classifying the wireless carrier used by the partner terminal (S22).

Next, in FIG. 3, when a call is transmitted from a calling terminal to a partner terminal, a radio carrier currently used is displayed and a dial tone is sounded (S10). Then, based on the dial tone, if the partner terminal picks up the handset and responds (S11), it notifies the partner terminal of the type of the wireless carrier currently used (S12).

[0008]

As described above, according to the present invention, when a call from a partner terminal is received, a ring tone corresponding to the type of the received wireless carrier is sounded and this type is displayed. It is possible to easily determine whether the call charge of the line currently used is high.
