Description

  The present invention relates to a wireless communication system, a calling terminal, and a wireless communication method for establishing wireless communication between a calling terminal and a called terminal through an exchange.

  For example, wireless communication terminals such as mobile phones and PHS (Personal Handy phone System) are widely used as communication devices capable of exchanging information regardless of location and time. However, due to its ease of portability, mobile phone manners in public places such as trains, hospitals, and movie theaters have become problems. For this reason, the user on the called side (hereinafter simply referred to as the called party) takes measures to prevent the user from starting a call by turning off the mobile phone or setting the manner mode. Therefore, even when the calling user (hereinafter simply referred to as the calling party) is urgent, a situation occurs in which the calling party is not transmitted to the called party in real time. There was a problem that it was not possible to cope with.

  Therefore, using a mobile phone equipped with a recent e-mail transmission / reception function, after making a notice of urgency (hereinafter simply referred to as urgency) by e-mail, requesting a call, etc. A method of starting a call after confirming the situation is conceivable.

  However, the above-described method involving electronic mail requires complicated mail input work before a call. In addition, since it is not possible to confirm whether or not the caller has seen the mail, there has been a situation in which a call is started without the caller's intention being communicated.

  Conventionally, a cellular phone has been provided with an answering machine answering function. For example, if the called party is in a conference and cannot start a call, the answering machine answering function can be activated if the answering machine answering function is enabled. The caller's message can be stored, and after the conference is over, the message stored in the answering machine answering function can be heard.

  However, in the above method using the answering machine answering function, the answering machine can be used only when the called party is ready to make a call regardless of the content of the message from the calling party (such as urgency). The message stored in the response function is confirmed and the content (whether it is urgent or not) is grasped, and there is a problem that it is not possible to deal with the content with high urgency.

  Therefore, even if the answering machine answering function of the mobile phone possessed by the called party is enabled, a voice message that prompts the calling party to send a control signal together with the answering machine answer is sent to the calling terminal, When a control signal of the DTMF (Dual Tone Multi Frequency) method is transmitted from the caller's telephone in response to the operation input of the caller, the incoming call is received by a notification means such as a ring tone or a vibrator included in the mobile telephone of the called party A technique for notifying a person of urgency is disclosed (for example, Patent Document 1).

JP-A-11-27380

  However, since the control signal described in Patent Document 1 described above needs to be processed also in the exchange that relays the calling terminal and the called terminal, the load on the exchange is great. Also, if the caller is truly urgent because he / she will send an urgency after hearing a voice message prompting the control signal sent with the answering machine answer (after the call is received) Was accompanied by annoyance.

  Therefore, in view of such a problem, the present invention provides a wireless communication system and a calling terminal capable of notifying an emergency level from a calling terminal to a called terminal without going through a switch before starting a voice call. And a wireless communication method.

  After the calling terminal receives the preparation completion information from the called terminal, that is, after the communication line is established between the calling terminal and the called terminal, emergency level information indicating the urgency level of the calling is displayed. The transmission configuration allows the emergency level information to be directly transmitted from the calling terminal to the called terminal without going through the exchange, that is, without burdening the exchange with a complicated processing load. In addition, since the notification unit of the incoming call terminal notifies the emergency level information during the call (during the notification of the incoming call), whether or not the call is urgent to the called party without starting the call. Can be determined. Therefore, in the case of an emergency, it is possible to prompt the callee to respond immediately.

  The call control unit may transmit emergency level information through a traffic channel. During the call, the traffic channel (TCH) can be used, but the actual voice has not yet been allocated, so the emergency level information can be easily identified and extracted by transmitting the emergency level information through the TCH. It becomes.

  The notification unit may notify the emergency level information regardless of the manner mode setting state. This makes it possible to reliably transmit the caller's emergency level information to the called party regardless of the status of the called party.

  After receiving the emergency level information, the incoming call terminal notifies the detection unit that detects an identifier indicating the emergency level information, and notifies the notification unit that there is an incoming call with a setting according to the detected identifier. And a setting control unit for causing the controller to operate. This makes it possible to transmit the caller's emergency level information to the called party more reliably.

  In order to solve the above-mentioned problems, another typical configuration of the present invention is a calling terminal that performs radio communication with an incoming call terminal via an exchange. An operation unit that accepts input of emergency level information to be shown, and establishes a communication line with the exchange according to the call input, and the exchange establishes a communication line with the called terminal according to the establishment of the communication line. After the establishment of the communication line between the calling terminal and the called terminal, the preparation is completed indicating that the voice communication with the calling terminal transmitted by the called terminal is ready. A call control unit that receives information and transmits emergency level information to the called terminal.

  In order to solve the above problems, still another typical configuration of the present invention is a wireless communication method using a calling terminal, an exchange, and a called terminal. Accepts call input and emergency level information indicating the urgency level of a call, establishes a communication line with the exchange in response to the call input, and the exchange establishes a communication line with the calling terminal The communication line between the calling terminal and the called terminal is established by establishing the communication line between the calling terminal and the called terminal. After the communication line with the calling terminal is established, Preparation completion information indicating that preparation for the start of voice communication has been completed is transmitted to the calling terminal.
