Description

  The present invention relates to a telephone terminal having a built-in telephone book for registering personal information.

  In the current telephone service, there is a number notification service in which the telephone number of the caller's phone terminal is notified to the receiver. Normally, when a mobile phone arrives, the caller's telephone number is received and recorded in the call log. ing.

  In addition, after communication, if there is no registration in the phone book in your terminal for the communication partner that remains in the call record, enter the name and email address of the other party based on the notified phone number, Can be added to the phone book.

  However, it is troublesome to manually enter personal information such as the name and email address of the other party. In particular, inputting characters using a numeric keypad takes time and effort. Further, there is a risk of erroneous input due to key operations.

  The present invention has been made in such a background, and it is intended to enable the telephone terminal to automatically acquire the personal information of the other party during a call without any special effort. To do.

  The telephone terminal according to the present invention is a telephone terminal having a built-in telephone directory for registering personal information, and detecting means for detecting a silent period during a call with the other terminal, and at least a silent period at the own terminal is detected. A notification request means for requesting notification of the personal information of the user stored in the terminal to the partner terminal by a predetermined voice signal, and the individual from the predetermined voice signal received from the partner terminal in response to the request Information extracting means for extracting information and registration means for registering the extracted personal information in a telephone directory in association with the telephone number of the counterpart terminal are provided.

  The silent period during a call is automatically detected, and the personal information of the partner terminal is requested by an audio signal during the silent period. The partner terminal also sends back personal information by voice signals using the silent period. There may be a case where the length of the silence period is not sufficient to finish transmitting the predetermined information, but in this case, the retry is performed in the subsequent silence period.

  Preferably, the notification requesting unit confirms whether or not personal information corresponding to the telephone number of the partner terminal is registered by referring to a telephone directory built in the terminal when a call is received from the partner terminal. If not registered, request notification of personal information. This eliminates the waste of re-acquiring personal information of a registered partner.

  The notification request unit may make a notification request for each of a plurality of items including at least a user name and an email address. By making the request and acquisition for each item possible, it becomes easy to acquire information using a silent period.

  Other configurations and operational effects of the present invention are described in detail below.

  According to the present invention, unregistered personal information (mainly name and e-mail address) of a call partner is obtained using a normal call opportunity without requiring any special operation by the user and without being aware of it. It becomes possible to do.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. Here, a mobile phone terminal will be described as an example.

  FIG. 1 is a diagram for explaining the concept of the present invention.

  The telephone terminal 100a and the telephone terminal 100b are connected to a mobile phone network by a base station (not shown) via a wireless interface and can perform communication for a call. Usually, there are sporadic periods of silence during this call. As shown in FIG. 1A, in the present invention, a silence period is detected based on an input signal from a microphone, and as shown in FIG. Request notification of personal information. Upon receiving the information notification request, the counterpart terminal encodes the requested personal information using a silent section and notifies the requesting terminal of the information by a voice signal. This audio signal is a signal obtained by modulating sound with coded personal information. For example, modem sounds and fax sounds can be used. Further, the received personal information is registered in the internal telephone directory. Personal information is information such as names and email addresses.

  FIG. 2 is a block diagram showing a schematic hardware configuration of the telephone terminal 100 shown in FIG.

  The telephone terminal 100 includes a control unit 101, a communication unit 103, a display unit 104, an operation unit 105, a storage unit 106, a voice processing unit 110, a calendar / clock unit 113, and a voice processing unit 110 that are connected to each other via a bus 115. A speaker 111 and a microphone 112 are provided.

  The control unit 101 includes a CPU and the like, and controls each unit of the telephone terminal 100 and executes necessary processes. The communication unit 103 includes an RF unit, a modulation circuit, and the like, and performs wireless communication for communication, e-mail, WEB data, and the like with the base station via the antenna 102.

  The storage unit 106 includes a memory such as a ROM and a RAM, and stores programs and data such as an OS and various applications executed by the CPU. The ROM may include a rewritable nonvolatile memory such as a flash memory.

  The audio processing unit 110 includes an audio encoder, decoder, DA converter, AD converter, and the like, and performs audio output to the speaker 111 and audio input from a microphone. Furthermore, the present embodiment has a function of generating an audio signal obtained by modulating personal information by a predetermined method and a function of demodulating such an audio signal.

  The calendar / clock unit 113 includes RTC (Real Time Clock) and provides date and time information and a timer function.

  In addition, although not illustrated, the telephone terminal 100 includes functional units included in a normal mobile phone terminal, such as a power supply unit, a light emitting unit, and a vibrator. Moreover, you may further provide a camera part, a non-contact IC card function part, a GPS receiving part, etc.

  The personal information in the present embodiment is usually information registered in a telephone directory in a mobile phone terminal. As the specification of the request, there may be a method for requesting all personal information registered by the user of the counterpart terminal and a method for requesting by specifying a specific information item.

  FIG. 3 is a block diagram showing main functions of the telephone terminal according to the present embodiment. Main functions in the present embodiment include a silence detection unit 11, an information notification request unit 12, a notification information extraction unit 13, an information registration unit 14, an information notification request extraction unit 15, and an information notification unit 16. These functions are realized by the control unit 101.

  The silence detection unit 11 is a functional unit that detects a silence state based on a microphone input obtained from the audio processing unit 110. As will be described later, when the silence state of both terminals is detected, the silence state is detected based on both the partner voice signal obtained from the voice processing unit 110 and the microphone input.

  The information notification request unit 12 is a functional unit that generates an information notification request to the voice processing unit 110 in accordance with the output of the silence detection unit 11.

  The notification information extraction unit 13 is a functional unit that extracts the content of the information notification based on the partner voice signal obtained from the voice processing unit 110. Specifically, data sandwiched between a start bit and an end bit (that is, a stop bit) described later is extracted from the partner voice signal.

  The information registration unit 14 additionally registers the information obtained from the notification information extraction unit 13 in the telephone book 18 in the storage unit 106. Specifically, personal information such as the name and mail address of the other party is registered together with the telephone number of the other party terminal.

  The information notification request extraction unit 15 is a functional unit that extracts an information notification request transmitted from the partner terminal based on the partner voice signal obtained from the voice processing unit 110.

  The information notification unit 16 is a functional unit that sends out personal information of the terminal from the telephone directory 18 to the voice processing unit 110 in response to an information notification request from the counterpart terminal.

  FIG. 4 shows an example of a request format for each item that can specify the necessity of request for each information item. Items include the name of the other party (kanji), name (hiragana), email address, postal code, and address (kanji, address (hiragana)). The data structure for asynchronous serial communication includes 1-bit (8-bit) information item request setting data including 1 bit and 2 unused bits, and a start bit and an end bit added before and after the information item request setting data. Here, 1 bit indicating whether or not notification is required is required (“1”) or not (“0”) When a plurality of commands are used as a request using an audio signal, this indicates the type of command. Prepare data separately.

  FIG. 5 shows an example of an item response format.

Each item is composed of a combination of an item type header indicating the type of the item, a data length indicating the length of data to be transmitted, and data. All of these items have a data structure for asynchronous serial communication sandwiched between a start bit and an end bit. For example, the following hexadecimal data can be used as the item type header.
0x01: Opponent name (kanji)
0x02: Name (Hiragana)
0x03: E-mail address 0x04: Postal code 0x05: Address (Kanji)
0x06: Address (Hiragana)
0x07: N / A (Not Available)
0x08: N / A

  The necessity of notification of each item can be appropriately set by the user through a user interface screen (not shown).

  As shown in FIG. 6, when a call is started after a silent state, the information notification is stopped. When the end bit cannot be received, the data receiving side determines that the received information is incomplete data and discards it. However, data that has been confirmed to be correctly received in item type header units may be stored. Further, on the terminal side for notifying information, only one item of data may be included between the start bit and the end bit, and notification may be made independently for each item.

  If the end bit is received, it is determined that the information has been correctly received, and the name and mail address are automatically input using this information when adding the telephone number after the communication.

  Next, a processing example of the telephone terminal in the present embodiment will be described with reference to a flowchart.

  FIG. 7 shows processing related to personal information notification performed when a call is received.

  First, it is checked whether or not the other party's telephone number has been notified (S11). If not notified, the telephone number of the other party is unknown, so this process ends.

  If notified, it is checked whether the name and mail address are registered in the internal telephone directory for the telephone number (S12). If registered, the subsequent steps are unnecessary, and the process is terminated.

  If not registered, the silent period during the call is monitored thereafter (S13). Specifically, it is determined that there is no sound when the loudness (signal level) input from the microphone is smaller than a predetermined value. When such a silent state continues for a predetermined time, the above-mentioned request for notification of personal information is transmitted (S14). The predetermined time here is a relatively short time for eliminating an instantaneous silence state. However, even if the silent state continues for a predetermined time, it is not known whether there is a silent period enough to complete transmission of the request thereafter. As will be described later, it is assumed that the silent period can end before the transmission of the request is completed. In such a case, even if transmission is in progress, transmission of the request is stopped. If the transmission of the information notification request is not successful, the process returns to step S13 and waits for the next transmission opportunity.

  After the transmission of the information notification request is successful, when a voice signal representing personal information is received from the partner terminal, the personal information is extracted and temporarily stored in the memory. The transmission of the personal information from the other party is performed when a silent period is detected at the other party terminal. If all the requested information has been successfully received (S16, Yes), the information is additionally registered in the telephone directory together with the telephone number (S17).

  When the call is finished, this process is finished at that time.

  The addition of information to the telephone directory in step S17 may be automatically performed, but the user's intention may be confirmed as a registration condition. In this case, for example, a confirmation message may be displayed on the display screen as shown in FIG. 8 and registration may be performed only when the user has permission. In this example, the confirmation message is “Your phone number (email address) has been acquired. Do you want to register it in the phone book?”. Here, the name of the acquired partner is inserted in “XX”.

  FIG. 9 is a flowchart showing an example of a call process of a caller-side telephone terminal corresponding to the call process on the called side in FIG.

  When the telephone terminal on the calling side also receives an information notification request from the other terminal during a call (S21, Yes), the silent period is monitored based on the subsequent microphone input of the own terminal (S22). When the silent period is detected, the requested information is started to be transmitted by the audio signal (S23). Thereafter, steps S22 and S23 are repeated until the transmission is completed. If the silence period is interrupted, wait for another silence period. When the transmission of all requested information is completed (S24, Yes), the process returns to step S21.

  In the above description, the information notification request is performed from the receiving terminal to the transmitting terminal. However, it may be performed from the calling terminal to the receiving terminal during the call. In this case, it is natural that the calling terminal has registered the telephone number of the receiving terminal in the internal telephone directory or the user has directly designated the telephone number manually, and in any case, the telephone number of the receiving terminal is known. It is. Since the notification request is not required for the other party registered in the phone book, the case of manual input is the target of this processing. However, even if registered, for example, when only a name and a telephone number are registered and an e-mail address is not registered, a notification request for only the missing personal information item can be made. In this case, it is possible to make a notification request for only the item according to the format of FIG.

  Further, when the notification request from the calling terminal to the receiving terminal is permitted, there is a possibility that the notification request from both terminals occurs in duplicate (that is, the notification request conflicts). In order to cope with such a conflict, it is preferable to provide a conflict adjustment means for adjusting the conflict between the request from the counterpart terminal and the request from the own terminal.

  The contention adjustment means is realized by the control unit 101, for example, and as shown schematically in FIG. 10, the terminal with the higher priority first receives an information notification request based on a predetermined criterion for determining the priority. The terminal having the lower priority order makes an information notification request after transmitting all of the requested personal information or after a predetermined long waiting time. “After a predetermined long waiting time” means, for example, when a predetermined time has elapsed after the start of one call.

  The criteria for determining the priority are, for example, comparison of the phone numbers of both terminals (the larger one is based on the size of the number itself, the added value of each digit value of the number, etc.), outgoing / incoming calls Any standard that can prioritize either one of the two terminals, such as another (for example, the destination side first), can be adopted.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made. For example, a mobile phone terminal has been described as an example of a telephone terminal, but the present invention can also be applied to a fixed telephone terminal. It can also be applied to an IP phone using the Internet.

  Even if there is a microphone input at the partner terminal, the information (including information notification request) is transmitted by voice signal when there is no microphone input at the own terminal. It is good also as a structure which transmits. In this case, as described above, the other party's voice signal is also input to the silence detecting unit 11 to detect silence at the other party terminal.

It is a figure for demonstrating the concept of this invention. FIG. 2 is a block diagram showing a schematic hardware configuration of the telephone terminal shown in FIG. 1. It is a block diagram which shows the main functions of the telephone terminal in embodiment of this invention.
