Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems in a conventional method for originating/incoming calling of telephone that a caller does not notice that he/she has input a wrong number before a callee takes a receiver and speaks at a speaker, that the caller does not confirm the number since he/she does not think it to be wrong, and that a calling state cannot be confirmed without fitting the receiver to the ear quickly. <P>SOLUTION: A message RGT213 is stored in a call-incoming set 200 in advance. When a call incomes, the call-incoming set generates a ringing tone 203, and establishes virtual voice connection (virtual RGT state 210) between a call-originating set 100 to transmit 213 the message RGT to the call-originating set 100 before off-hooking by a user. The call-originating set 100 generates a voice of a received message RGT. By hearing the message RGT, the user of the call-originating set can confirm that a callee desired to call is surely called presently. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a calling / incoming method for a public communication terminal device having a voice communication function, such as a cellular phone, and a communication terminal device using this method.

Calling / incoming operations in PDC (Personal Digital Cellular) voice communication are defined in the standard [RCRSTD-27 Digital Car Telephone System], but a simple sequence is used to help understand the problems of the present invention. The outline of the operation will be described with reference to FIG.
In a normal mobile phone, a “calling” message 101 (hereinafter called “calling”) from a calling terminal device 100 (hereinafter referred to as “calling machine”, but referred to as a calling side in FIG. However, in order to inform the calling user that the called device is being called at the time 201 received by the called party in FIG. 8, the so-called ring tone 103 (off-hook information from the receiving terminal device through the speaker of the calling terminal device) A sound that rings during the waiting period (hereinafter referred to as RGT) is generated. As a sound used for RGT, a sound signal generated in a public exchange network, a sound signal generated inside a generator, or the like is used. A detailed explanation is omitted, but when the other party is busy, a so-called busy signal is sounded, and when the other party is turned off or is out of reach of radio waves (that is, cannot be called), an appropriate announcement is made. (Synthesized voice signal generated by the public switched network).
These sounds are simply intended to inform the calling user that they are ringing, talking, or uncallable, so a monotonous electronic sound, regardless of who is actually calling. Or, there are many cases where the repetition of the synthesized voice is adopted, and there is a problem that the user's entertainment and customization are low as compared with the diversity of ringing sounds on the called side, which is known as a so-called ringtone.

While the RGT is ringing, for example, the telephone number of the calling side is displayed on the called side terminal, and it is possible to know who the call is from without having to take the handset. In this way, a certain amount of information is transmitted from the calling side to the called side even during a call.
On the other hand, if the calling party has typed in the wrong number, it is necessary to put the handset on the ear immediately in order to hear the above-mentioned signal sound, although it is likely that you will notice the mistake if you look closely at the typed number. In many cases, the information on the called side is not transmitted except for the above-mentioned information and only a simple RGT is heard during the call, so that the user does not notice a mistake until the other party answers the call. The fact that a connection error is noticed only after voice communication with the other party is started in this way indicates that the mutual authentication operation prior to connection is incomplete in the conventional call / incoming call method. There is nothing else.
Standard [RCR STD-27 Digital Car Telephone System]

1) During the call, the caller can only hear the dry and dry RGT, and there is a problem that the user's entertainment and customization are poor.
2) When the caller typed the wrong number and did not confirm it well, there was a problem that the other party did not notice the mistake until he answered the call.
3) The conventional calling / incoming method has a problem that the mutual authentication operation prior to connection is incomplete.

According to the present invention, there is provided a message storage procedure for storing an arbitrary voice call message in each of a plurality of communication terminal devices capable of making a voice call to each other via a public telephone line network.
When the first communication terminal device of the plurality of communication terminal devices receives a call from the second communication terminal device, the first communication terminal device before the user of the first communication terminal device performs a receiving operation A provisional RGT state configuration procedure for establishing a communication line capable of transmitting and receiving voice information between the second communication terminal device and the second communication terminal device;
A message RGT transmission procedure for transmitting the voice call message from the first communication terminal device to the second communication terminal device in the temporary RGT state;
The second communication terminal apparatus includes an RGT ringing procedure for ringing the received voice call message until the handset is off-hooked in the first communication terminal apparatus.

In the calling / incoming call method of the present invention, in the calling / receiving terminal device having a voice communication function, voice information or image / moving picture information arbitrarily created by the user is stored in the information storage unit. When the incoming terminal device receives a call from the outgoing terminal device, the incoming terminal device transmits the stored information to the outgoing terminal device before off-hook. The originating terminal device sounds user-created information transmitted from the terminating terminal device.
Therefore, the calling side can confirm that the caller is calling by the sound without fail, and the effect that the mistake of making a call is reduced can be obtained.
Further, the calling terminal device can provide a bidirectional service by responding to the receiving terminal device with dial push sound or voice according to the content of the message RGT information.
As a result, the user of the calling terminal device can acquire information in advance before the user of the receiving terminal device actually responds to the incoming call, thereby improving the entertainment and customization of the user. can get.

Before describing Embodiment 1 of the present invention, the fundamental difference from the present invention will not be confused and misunderstood as a technique related to incoming call alert melodies known as [ringtone]. This will be explained in advance.
The so-called [ringtone] is used to notify the user of the incoming call terminal device that the incoming call has been received. From the speaker of the incoming call terminal device, the music data stored in the incoming call terminal device in advance to off-hook after the incoming call is detected. It is made to ring during. There is also known one that selects music from a plurality of music data stored at this time in accordance with a call destination and rings it.
According to the present invention, the music data stored in the receiving terminal device is made to ring from the calling speaker to the calling user until the receiving side removes the hook.

Embodiment 1 FIG.
Before describing the calling / incoming call method of the present invention, the configuration of a public communication system (hereinafter referred to as a network system) in which the present invention is used will be described with reference to FIG.
A network system to which the present invention is applied includes a public switching network (telephone network) 50 as shown in FIG. 1 and a calling terminal device 1 and a receiving terminal that are connected to or can be connected to the public switching network 50 by radio or wire. The apparatus 2 is included. Although there are a plurality of terminal devices, only one of each is shown here for convenience of illustration and explanation. The transmitting terminal device 1 and the receiving terminal device 2 may be capable of communicating while moving, or may be fixed. A network system in which a transmitting terminal device 1 (hereinafter, also referred to as a generator) and a receiving terminal device 2 (hereinafter, also referred to as a receiver) perform wireless communication through the public switching network 50 is configured.
The calling terminal device 1 and the receiving terminal device 2 are generally the same hardware, but here, for convenience of explanation, the calling side (outgoing terminal device 1) and the receiving side ( The incoming terminal device 2) is distinguished.

Next, the internal configuration of the transmitting terminal device 1 and the receiving terminal device 2 of FIG. 1 will be described with reference to FIG. Both the transmitting terminal device 1 and the receiving terminal device 2 have the same configuration. Details of each block shown in FIG. 2 will be described below.
The operation unit 11 is a part for performing user key operations (not shown), and is a so-called keyboard. The display unit 12 is a device such as an LCD (liquid crystal display unit) and a driver necessary for a screen display operation. The call control unit 13 performs communication protocol control.
The voice call message storage unit 14 (hereinafter referred to as message RGT storage unit 14) stores message RGT data set by the terminal device. The incoming melody storage unit 15 stores an incoming melody for notifying the incoming user that there is an incoming call.

The multimedia code / compositing unit 16 combines the message RGT data and the incoming melody data. The communication control unit 17 controls the physical layer of communication. The voice recognition unit 18 performs parameter conversion on the transmission voice from the generator as an interactive service. The bidirectional control unit 19 determines a process to be performed next from the parameterized voice.
The message RGT setting information unit 20 is information for associating telephone number information of a telephone bowl (not shown) and message RGT data. This will be described with reference to FIG. Although the message RGT is described as being a melody in FIG. 3, the message RGT is not limited to a melody, but may be a recorded voice or a user announcement. The number of message RGTs may be one, but a plurality of messages RGT are registered, and these are linked in advance with the telephone number of the other party with the possibility of communication, which is stored in the message RGT setting information storage unit 20. .
The data link unit 21 determines and selects message RGT data associated with the received telephone number. Moreover, although it has a speaker / microphone / antenna / power supply, etc., since all are well-known, detailed description is abbreviate | omitted.

The operation of the message RGT will be described with reference to FIG. 2, FIG. 3, FIG. 4, FIG.
In the present invention, a state called a provisional RGT state is provided when making a call. The provisional RGT state indicates that the calling / incoming user continues to call, and the transmission / reception path is connected (a state in which a telephone line is established). This will be described.
First, a sequence for transitioning to the temporary RGT state in FIG. 5 and how to display the outgoing / incoming call display to the user will be described.
The caller 100 notifies the callee 200 that there is a communication request through the public exchange network 50 by a call setting message 101 (step 51).
The call setting message via the public exchange network becomes the call setting 201, and the destination device 200 that has received the call setting 201 performs an incoming call display 202 on the display unit 12 to indicate that the user has received an incoming call, and an incoming melody storage unit. The incoming melody stored in 15 is compounded by the multimedia code / compositing unit 16 and is played from the speaker (step 52).

Next, the incoming device 200 notifies the virtual RGT start message 210 via the communication control unit 17, receives the virtual RGT response 110 from the generator 100, confirms that it has transitioned to the temporary RGT state, and then calls A message 211 is notified.
Next, before the user removes the hook, a response message 212 is notified immediately after the call message 211 is notified in order to make a temporary connection of the transmission / reception path. Then, the transmission / reception path is provisionally connected (step 53) (the communication control unit 17 is a provisional telephone line establishment means according to the present invention).
In the provisional RGT state, it behaves as if the user is still calling. Therefore, even if the generator 100 receives this response message 212, the calling device does not display the call, the called device 200 does not display the call, and the ringing melody 203 is continued (step 54).

Along with the connection of the transmission / reception path, the receiver 200 transmits a message RGT 213. The destination device 200 decrypts the message RGT stored in the message RGT storage unit 14 by the multimedia code / composite unit 16 and transmits it from the communication control unit 17 (step 56, message RGT transmission procedure).
The generator 100 rings the received message RGT from the speaker in the same manner as the conventional RGT is ringed through the multimedia code / composite unit 16 (step 57). Steps 53 to 57 are referred to as a provisional RGT state configuration procedure.
In this way, the message RGT stored in the incoming machine is sounded from the speaker of the originating machine until the user of the incoming machine goes off-hook (referred to as RGT ringing procedure). A circuit for ringing the received message RGT from the speaker is called voice message ringing means. Note that the operation in the case of busy, power off, out of service area, etc. is the same as the conventional one, so detailed description is omitted.

After the above, when the arrival machine detects the user's off-hook 214 with the operation unit 11 (step 58), the call control unit 13 notifies the pseudo response message 215 through the communication control unit 17. This is the same as the response message 215 after the off-hook 214 in FIG. Upon receiving the pseudo response message 215, the generator 100 transmits a pseudo response confirmation message 116 from the call control unit 13 through the communication control unit 17 to display the display unit 12 during communication. When the destination device 200 also receives the pseudo response confirmation message 116, it stops the composite of the message RGT of the multimedia code / composite unit 16, displays the active call on the display unit 12, and transitions to a voice call state (steps 59 to 59). 60).
Thereby, a voice call starts.
Since the operation and operation at the end of the call are the same as in the prior art, the description is omitted.

Next, a method for creating and setting message RGT data will be described.
As the message RGT data, voice or music may be input from a microphone and stored in the message RGT storage unit 14 or paid / free software downloaded from the Internet may be stored (referred to as a message storage procedure).
A method for setting the message RGT data stored in this manner in accordance with a calling user assumed in advance will be described.
As shown in FIG. 3, the user of the arrival machine 200 sends a message RGT stored in the message RGT storage unit 14 and a telephone number stored in a telephone basket (partial phone number storage unit) (not shown) from the operation unit 11. Perform an association operation with. The association here is to determine which music (or message) is to be sounded for which destination. The associated information is stored in the message RGT setting information storage unit 20 (referred to as a message registration procedure). The message RGT setting information storage unit 20 is also called message registration means.
When the incoming machine 200 receives an incoming call, the message RGT to be sounded is determined from the telephone number of the outgoing machine 100 (transmitted at the same time as the incoming call) and the setting information stored in the message RGT setting information storage unit 20. Then, a reproduction request is made to the multimedia code / composite unit 16 (referred to as registration message RGT transmission procedure).

  In the case of the one shown in the first embodiment, the use can be started only by the setting for the own device. In addition, for example, a method in which the user of the arrival machine registers the message RGT data and the origin in the public exchange network 50 in advance and notifies the RGT registered to the origin from the network is also conceivable. In this method, the number of registered users cannot be increased due to the memory capacity of the server. According to the method of the present embodiment, the number of RGTs corresponding to the number of telephone book registrations can be registered. In addition, the RGT data itself can be selected without limitation by downloading the data.

Embodiment 2. FIG.
Next, the bidirectional function in the message RGT will be described with reference to the flowcharts of FIGS. The flow of FIG. 6 is a more detailed development of a part of the flowchart of FIG. 5 described in the first embodiment.
While the message RGT is ringing, the transmission / reception path is temporarily connected (step 55). Therefore, voice data can be exchanged between the generator and the receiver. The message RGT from the arrival machine is not mere music, but a voice requesting a response from the departure machine, for example, "If you really are Mr. A, please say a secret word" The user of the machine inputs the voice to the microphone (or reads out the typical response voice data stored in advance from the storage unit) and responds to the destination through the multimedia code / composite unit 16 and the communication control unit 17. I can do it. When the answering machine receives the response voice (step 57a), it inputs voice data to the voice recognition unit 18 through the communication control unit 17. The voice recognition unit 18 parameterizes the input voice data by voice recognition processing (step 57b). This parameter is input to the bidirectional control unit 19, and a process to be performed next is determined and a process request is made to each module of the destination machine (step 57C).
In this way, a bidirectional function during the ringing of the message RGT is realized. Steps 55 to 57C are referred to as a bidirectional RGT state configuration procedure.

Next, as an example of an actual service image of the interactive function, a service that can confirm whether or not the originator is qualified to log in to the destination machine will be described with reference to the flowchart of FIG.
This is a service that, when a call is received from the aircraft, the aircraft uses the message RGT to request the login password to be entered, and determines whether the incoming call from the aircraft is permitted or not It is.
The incoming machine receives the incoming call and transitions to the provisional RGT state (step 70). Then, in step 71, the message RGT is used to request the password input “What is your LOGIN password?”.
The user of the machine returns “***” and the password through the transmission / reception path (step 72).
The destination machine parameterizes the received password “***” by the voice recognition unit 18 (step 73).
The parameter is determined by the bidirectional control unit 19 as to whether the incoming call is from a permitted machine (step 74).
If it is an authorized user, communication is continued (step 75). If not permitted, the communication is disconnected (step 76).

  The call origination / incoming call method and communication terminal apparatus of the present invention can also be used for fixed telephones that are limited to mobile telephones.
