Description

  The present invention relates to a telephone terminal that is wirelessly connected to a mobile phone, and more particularly to a technique for remotely controlling a mobile phone that is wirelessly connected in response to an instruction from a call destination of the telephone terminal.

  Nurses working in hospitals consider the effects of electromagnetic waves on hospital equipment (precision equipment such as CT), and place private mobile phones in predetermined locations where there are no effects of electromagnetic waves in hospitals (for example, changing rooms) ) Is often stored. For this reason, there is a problem that outgoing / incoming calls (private calls) using a mobile phone cannot be performed during work.

  As a technique for solving the above-described problem, for example, in Patent Document 1, a mobile phone periodically acquires its own location information using GPS (Global Positioning System) mounted on the mobile phone. If the acquired location information is in a pre-registered wireless communication prohibition area, a technique is described in which it is transferred to a hospital telephone (extension telephone) using a predetermined transfer service such as Voice Warp (registered trademark). Yes.

  Thereby, the nurse can receive an incoming call for private use (incoming call addressed to the mobile phone) even during work.

Japanese Patent Laying-Open No. 2015-70372

  However, the technique of Patent Document 1 does not consider transmission (transmission from a mobile phone). For example, when making an emergency call to a family member or acquaintance, it may be possible to make a call using a fixed telephone line on the hospital side. It is not desirable for nurses to use telephone lines for private use, albeit urgently.

  Even if a call is made using a fixed telephone line on the hospital side, there may be a case where the call destination is misunderstood as an incoming call from an unknown fixed telephone and does not respond to the incoming call.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a telephone device capable of making an emergency call without using a fixed telephone line on the hospital side.

  In order to solve the above problems, the present invention provides an extension telephone that is wirelessly connected to a predetermined mobile phone using short-range wireless communication, and a mobile phone remote control means for remotely controlling the wirelessly connected mobile phone; The predetermined mobile phone is wirelessly connected to the remote control permission extension storage means for storing the terminal ID of the predetermined mobile phone in advance in association with the extension number of the extension telephone permitted to remotely control the mobile phone. In the state, when an incoming call arrives, a call between the extension telephone and the own extension telephone is established automatically by answering the extension call, and the caller source number that established the call is extracted. A caller number match determination unit that determines whether or not a telephone number that matches the caller number exists in the remote control permission extension storage unit, and a phone number that matches the caller number is the If it exists in the remote control permission extension storage means, the terminal ID of the mobile phone corresponding to the caller source number is referred to and it is determined whether or not the mobile phone corresponding to the terminal ID of the referred mobile phone is wirelessly connected. When the corresponding mobile phone connection determination means and the mobile phone corresponding to the terminal ID of the referenced mobile phone are wirelessly connected, the wireless connection is established from the voice received from the extension telephone set as the call originator. Remote control voice signal receiving means for receiving a voice signal for remotely controlling the mobile phone, and if the remote control voice signal receiving means accepts a voice signal for remotely controlling a mobile phone connected wirelessly, The mobile phone remote control means controls the mobile phone remotely according to the received audio signal.

  According to the present invention, a telephone device accommodates a mobile phone existing in the vicinity and can perform remote control related to outgoing / incoming calls of the mobile phone, and can make a call from another telephone device registered in advance during a call. When the control command is received, the remote control is used to make a call using a mobile phone.

  As a result, the nurse can use the fixed telephone line on the hospital side in the telephone device by remotely controlling the mobile phone using an extension phone installed in a nurse center or the like during work and making a call from the mobile phone. It is possible to make an emergency call without urgent.
