Description

  The present invention relates to a mobile communication telephone, and more particularly, to a mobile communication telephone that can reliably call back from an emergency call destination when an emergency call is made to a fire department or a police station using a mobile communication network.

  Emergency calls to the fire department (119) or police station (110) are often mentally upset by the whistleblower, and the call is made without talking about important requirements such as the name of the whistleblower or the location of the whistleblower. May be cut off. Therefore, in a conventional fixed network switching system, when a call path is formed by an emergency call, each exchange that forms the call path holds information indicating that it is an emergency call connection, and the caller lowers the handset. Even when the talk is over, a system is adopted in which the call path is temporarily suspended without being immediately released and the caller can call again with a call back operation from an emergency call destination such as a fire department or police station. ing.

  Similarly, even in a mobile network switching system, after an end-of-call operation from a mobile communication telephone, it is possible to call back from an emergency call destination, but if the mobile communication telephone is turned off, it will be put on hold. The call path that has been released is released, and the call cannot be recalled.

  In addition, for the purpose of mischief to prevent call back by intentionally turning off the power supply of mobile communication phone after an emergency call by utilizing the fact that the call cannot be returned by turning off the power supply of the mobile communication phone. In the situation where there is no end to the fun of emergency calls such as emergency calls such as calling off the power, turning off the power supply and releasing the call path, and issuing emergency calls many times, it may interfere with the original emergency call reception work There is a serious problem.

  Based on FIG. 5, a connection path when a call is made from the mobile communication telephone 100 to the emergency call reception center 70 such as a fire department or a police station will be described. Briefly describing the emergency call, the reception table 60 of the emergency call reception center 70 is called from the mobile communication telephone 100 through the base station 20, the mobile network switch 30, the fixed network switch 40, and the report reception system 50.

  The emergency call is connected by the response operation of the reception desk 60 for this call. However, even if the end operation of the mobile communication telephone 100 is performed after a call, the connection is not released, and the reception desk The call can be returned from 60, and the connection is released only by the disconnection operation from the reception desk 60 after the call is made again.

  A call connection sequence between the mobile communication telephone and the mobile network switch will be described. The sequence shown in FIG. 6 (a) is a normal general call connection sequence, and the release signal is returned from the mobile network switch and the connection is released / disconnected only by the call end operation on the caller side after the call. The On the other hand, in the case of an emergency call, as shown in the sequence of FIG. 6 (b), the mobile network switch recognizes it as an emergency call, and the mobile network only receives the call termination operation after the call. A release signal is not returned from the exchange, the connection remains maintained, and a call can be made again by calling back from the reception desk 60. The disconnection in the case of an emergency call is possible only by the disconnection operation of the reception desk 60.

  However, in the conventional mobile communication telephone shown in FIG. 7, the power switch 180 is turned off when the caller performs a power off operation after the call-end operation, and the radio battery 110 and the control unit 120 have a main battery. The power is not supplied from 160, the operations of the radio unit 110 and the control unit 120 are stopped, the connection between the mobile communication 100 and the base station 20 described with reference to FIG. It becomes impossible to do.

  FIG. 8 shows a flowchart for explaining the operation at the time of emergency call by the conventional mobile communication telephone. As shown in the figure, even if the caller who made the emergency call performs the call end operation in step 204, the connection is not immediately cut off, and whether or not the release signal is received by the operation of disconnecting the reception desk is determined. The call is released in step 210 only when a release signal is received as determined by 205.

  If no release signal is received, the call is being connected (step 220), and if there is no call-off operation (step 221) and there is a call back from the reception desk (step 234), an incoming call display (step 235). In response to the response operation (step 236), the call is again in progress (step 203), but when the power switch 180 is turned off (step 213) by the power off operation (step 221), the call is disconnected (step 214). It becomes an off state (step 250), and the call back from the reception desk becomes impossible.

  As described above, as a method for solving the problem that the call cannot be returned from the reception stand when the power switch is turned off in the mobile communication telephone, “mobile communication telephone” described in Patent Document 1 below. If the telephone number for emergency call such as 119 or 110 is registered in the mobile communication telephone and the caller dials the telephone number for emergency call such as 119 or 110, the mobile phone The telephone control unit of the notification telephone detects that an emergency call has been made, and the power supply is connected so that the telephone control unit of the mobile communication telephone does not turn off for a certain period of time regardless of the caller's operation. It is to continue the state. In addition, this “mobile communication telephone” is characterized in that it is provided with off-impossibility releasing means for canceling the power-off disabling process.

  Further, in the “mobile communication device and mobile telephone exchange” described in Patent Document 2 below, when an emergency call is made, a base station receives a transmission signal from a mobile communication telephone, and the transmission signal Is sent to the central control unit of the mobile switching center, and the central control unit compares the emergency call telephone number such as 110 or 119 stored in the storage device and writes the emergency call destination call data to the storage device if they match. Execute call processing.

  At the end of this communication, the central control unit checks whether this communication is for the emergency call destination, and if it is for the emergency call destination, the central control unit cannot turn off the power after the end of the call (hereinafter referred to as the power supply). The base station instructs the base station to transmit a signal that cannot be turned off, and the base station sends a power-off impossible signal to the mobile communication telephone. The mobile communication telephone that has received the power off disable signal sets the power off disable monitoring timer value in the timer, and the timer set value remains even during the power off operation by the reporter during the timer value setting. As long as this is done, the power is prevented from being turned off.

The above Patent Documents 1 and 2 are listed below.
JP 10-32650 A JP 2000-216860 A

  However, although the mobile communication telephone of Patent Document 1 makes it possible to reliably turn off the power for a certain period of time after an emergency call, the call back from the emergency call destination can be made reliably. The condition that the mobile communication phone can be used for other calls is when a call back from the emergency call destination is made or when a certain period of time has passed, and there is always a call back from the emergency call destination. Not limited, depending on the content of the report, there may be no call back, if there is no call back, if the reporter uses the mobile communication phone for other calls, you will have to wait for a certain period of time, There is a lack of proper grounds for determining this fixed time setting, and it is difficult to make practical use.

  Further, in the mobile communication device and the mobile telephone exchange of Patent Document 2, each user of the mobile communication device does not perform a registration operation to the mobile communication device, and the emergency contact telephone number is changed. The caller can make a call back from the emergency contact even if no change registration is made, but the conditions under which the whistleblower's mobile communication telephone can be used for other calls are described in Patent Literature This is the same as the mobile communication telephone set described in No. 1.

  In the present invention, when an emergency call is made from a mobile communication telephone, even if the caller rushes to the power source by the end-of-call operation after the call, the call from the emergency call destination to the mobile communication telephone is called. It is possible to return the call reliably, so that the reporter can confirm the contents of the report from the reception desk, and when the call back from the reception desk is unnecessary, the call back operation is not performed from the reception desk. It is another object of the present invention to provide a mobile communication telephone that allows a caller to immediately make another call without waiting for a certain period of time after the call.

  In addition, for emergency calls for mischief purposes, even if the caller turns off the mobile phone, the mobile network connection status is maintained and the caller calls back to the caller and pays attention to the caller. A mobile communication phone that makes it impossible to repeatedly make emergency calls by making the communication path connected to repeated repetitive emergency calls. The purpose is to provide.

  In addition, the present invention provides a call back from the reception desk of the report destination even when the mobile communication telephone is turned off after the emergency call is made and the battery is removed from the mobile communication telephone. An object of the present invention is to provide a mobile communication telephone that can be used.

  The mobile communication telephone of the present invention is (1) a mobile communication telephone having a radio unit, a control unit, a display unit, an operation unit, and a main battery. The mobile communication telephone when it is detected that a power-off operation has been performed after an end-of-call operation at the operation unit of the mobile communication telephone when a call path is set with the reception desk of the mobile communication telephone Only when the reception of the release signal from the mobile network due to the disconnection operation of the reception stand is detected by continuously supplying power from the main battery to the radio unit and the control unit of the mobile unit and maintaining the connection state with the mobile network. It is characterized by having a function of releasing the connection.

  (2) A power switch that opens and closes a power supply path from the main battery to each function unit, and a power supply path provided between the power switch and the display unit and the operation unit. A first power change-over switch that opens and closes the power switch, and when the control unit detects that a power-off operation has been performed when a speech path is set with the reception board, the power switch Is controlled so as to be maintained in a conductive state, and the first power supply switch is controlled to be shut off.

  (3) When a communication path is set with the reception stand, if power supply from the main battery is interrupted, the wireless unit, the control unit, the display unit, and the operation unit are connected to the functional units. It is characterized by having a function of switching the power feeding path so that power feeding is performed from a backup battery.

  In addition, (4) a second power supply changeover switch that switches a power supply path to supply power from the backup battery to the wireless unit and the control unit when power supply from the main battery is interrupted is provided.

  Further, (5) when the power supply from the main battery is interrupted, the power supply switch includes a power supply switch that switches a power supply path so that power is supplied from the backup battery to the display unit and the operation unit. This is also used as the first power source switch.

  The present invention controls a wireless unit that communicates with a mobile network and controls the wireless unit even when the caller accidentally turns off the power by an end-of-call operation after the notification when making an emergency call from a mobile communication telephone. By providing a function that keeps the connection to the mobile network without turning off the power supply to the control unit, if there is a call back from the mobile network, it is directed to each functional unit in the mobile communication telephone by the instruction of the control unit The power supply is turned on to display the incoming call, and the caller's response operation makes it possible to make a call such as confirming the content of the call again from the reception desk at the report destination.

  In addition, even if the mobile communication telephone is turned off after making an emergency call for mischief purposes, the connection to the mobile network will continue, so the caller can be called back and Alerts to mischievous phone calls such as calling attention from the reception desk.

  Further, in the present invention, since the emergency call connection is released by the disconnection operation from the reception desk, when the call is not required to be called back, the connection is immediately established only by performing the disconnection operation on the reception desk side. The reporter is free to use the mobile communication telephone without waiting for a certain period of time as in the prior art.

  In addition, since the emergency call connection is released by disconnecting from the reception desk, the reception desk operator does not need to release the connection as in the prior art when the call is a call that does not require a call back. Since it is not necessary to perform a call back operation and the connection is maintained unless a disconnection operation is performed at the reception desk, repeated calls of mischief reports can be prevented. In the case of a general call, when the caller performs a call termination operation after the call, a release signal is returned from the fixed network, so that the connection with the mobile network is not continued.

  Furthermore, in the present invention, when an emergency call is made from a mobile communication telephone, even if the main battery is removed after the caller's call-ending operation, by supplying power from the backup battery, it is possible to Can be reliably called back and re-called. In addition, even when the remaining amount of the main battery is exhausted during an emergency call, power is supplied from the backup battery in the same manner, so that recall and re-call are possible.

  FIG. 1 is a block diagram of a mobile communication telephone according to the present invention, and FIG. 2 is a flowchart for explaining the operation thereof. 7 is different from the conventional mobile communication telephone of FIG. 7 in that a first power supply switch A181 that is controlled to be turned on / off by a control signal 126 from the information control unit 122 is provided, and the call connection is in progress in the flowchart of FIG. Even if there is a power-off operation (step 221) in (step 220), the wireless unit call is being connected (step 223), and the call back (step 224) can be performed.

  Further, the difference between the above-described mobile communication telephone of Patent Document 1 and the mobile communication device and mobile telephone switch of Patent Document 2 is that when the emergency call number registered in advance matches the power-off disabled state, Instead, after the call termination operation (step 204) after the call with the report destination (step 203), there is no reply of the release signal 205 (step 205), and the call is connected (step 220). When there is an off operation (step 221), the radio unit 110 and the control unit 120 are kept supplied with power from the main battery 160 via the power switch 180, and the call is connected. The release / disconnection of the call for the notification is made possible only by the disconnection operation from the reception desk 60.

  The operation of the first embodiment of the present invention will be described in detail with reference to the block diagram of FIG. 1, the relay scheme diagram of FIG. 5, and the flowchart of FIG. In the mobile communication telephone 101 of the present invention, the radio unit 110 performs radio communication with the base station 20, and the radio control unit 121 in the control unit 120 controls the radio communication.

  Not only an emergency call but when a connection path is set between the radio unit 110 and the base station 20 and a call is in progress (step 203), and then the call end operation (step 204) is performed by the operation unit 150 The radio control unit 121 determines whether or not the release signal is received from the base station 20 (step 205). If the release signal is received, the call release (step 210) is performed and the release signal is received. If not, the call connection (step 220) is maintained.

  In this state, if there is a power-off operation (step 221) at the operation unit 150, the power switch 180 is turned on as it is by the control signal 126 from the information control unit 122, and only the power switch A181 is turned off (step 222). And the power supply to the display unit 140 and the operation unit 150 is turned off.

  However, since the power supply to the radio unit 110 and the control unit 120 is not turned off, the call is being connected (step 223), and if there is a call back (step 224), the radio control unit 121 returns the call back. Is detected, the power switch A181 is turned on by the control signal 126 from the information control unit 122 (step 225), power is supplied to the display unit 140 and the operation unit 150, and an incoming call display (step 235) is performed.

  When a response operation (step 236) is performed on the incoming call display by the operation unit 150, the state again becomes a state of being in communication with the reception desk 60 (step 203). Incidentally, if the power off operation (step 211) after the call release (step 210) is performed, the power switch 180 is turned off, and the power supply from the main battery 160 to each functional block is turned off.

  FIG. 3 is a block diagram of the second embodiment of the present invention. The difference between the second embodiment of the present invention and the first embodiment of FIG. 1 is that the first power supply changeover switch that switches from the main battery 160 side to the backup battery 161 side when the power supply from the main battery 160 is interrupted. Even if the main battery 160 is removed (step 241) during call connection (step 220) in the flowchart of FIG. 4 by providing the A181 and the second power supply changeover switch B182, the first power supply changeover switch A181 and the second power supply changeover switch A181 The power source switch B182 is switched to the backup battery 161 side so that power can be supplied from the backup battery 161.

  The operation of the second embodiment of the present invention will be described in detail with reference to the block diagram of FIG. 3, the relay scheme diagram of FIG. 5, and the flowchart of FIG. The operation of the mobile communication telephone 102 of the second embodiment is the same as that of the first embodiment shown in FIG. 2 until the call connection (step 220) in the flowchart of FIG. If power supply from the main battery 160 is interrupted (step 241) while the call is being connected (step 220), the first power supply switch A181 and the second power supply switch B182 are turned off (step 242). The contact is switched to the power supply path side from the backup battery 161 so that power is supplied from the backup battery 161 to each functional block.

  As a result, power supply to the radio unit 110 and the control unit 120 is continued, so that the call remains connected (step 243), and if there is a call back (step 244), the incoming call is radio controlled. It can be detected by the unit 121 and the incoming call can be displayed (step 235). Then, a response operation (step 236) is performed on the incoming call display by the operation unit 150, so that the communication with the reception desk 60 is again made (step 203).

  Incidentally, if there is no main battery removal (step 227) after the power-off operation (step 221) during call connection (step 220), the operation is the same as in the first embodiment, and the first power switch Only the switch A 181 is turned off and power supply to the display unit 140 and the operation unit 150 is stopped. However, power supply to the wireless unit 110 and the control unit 120 is continued via the power supply switch B 182 that is in operation.

  In addition, in each switch shown in FIG. 3, the state of the contact position indicated by the broken line is the contact position when the switch is in the OFF state, and the state of the contact position indicated by the solid line is the contact position when the switch is in the ON state. It shows that there is. Further, the backup battery 161 in the second embodiment of the present invention is fixed in order to always supply power so that the stored contents of the memory 130 for storing various setting information and time information of the mobile communication telephone are not lost. It is usually impossible for the user to remove the backup battery 161 with a battery.
