Description

  The present invention relates to a mobile terminal such as a mobile phone, and more particularly to a technique for cutting off incoming calls from a party who does not wish to make a call.

  In recent years, many people have mobile terminals having mobile phone functions, and the ownership rate is expected to increase in the future. Mobile phones have the great advantage that they can easily make and receive calls whenever they are in an area where wireless communication with the base station is possible. Many people feel that they have to do it.

  For this reason, conventionally, when it is determined that the other party of the communication is not preferable during communication, when the nuisance call prevention key is pressed, the communication is disconnected and connected to the incoming call rejection service provided by the network. In addition, registration for rejecting subsequent incoming calls from the other party is performed, and a technique for rejecting incoming calls from an undesired registered party is proposed in Patent Document 1 and the like.

  However, when an incoming call arrives at a mobile communication device from an unfavorable partner, not to say a nuisance call, if you do not answer the incoming call or hang up immediately after answering, There is a concern that it may give a bad impression of, and affect the subsequent interpersonal relationship. Therefore, some people who own mobile phones are not really willing to answer the call when they receive a voice call, but they are unavoidable because they are socially or personally concerned. There are many cases where you will respond.

  As means for solving such a problem, Patent Document 2 includes level changing means for gradually lowering a transmission level and / or a reception level during a call in response to an operation of a specific key switch. When a specific key switch is operated, the transmission level and / or the reception level during a call are gradually lowered at a certain rate to gradually deteriorate the call quality, and the call is interrupted. By creating a state, a technology has been proposed that unilaterally disconnects the call without losing thanks to the other party by producing a phenomenon as if the mobile terminal moved to an area with poor radio wave environment. ing.

  According to the technique described in Patent Document 2, when there is an incoming call from an unfavorable partner to the mobile phone, means for automatically and gradually degrading the call quality and finally shifting to a disconnected state Therefore, the caller does not seem to have intentionally blocked the communication, and has the effect of helping to keep the future interpersonal relationship smooth. However, in the case of the technology described in Patent Document 2, When a specific key switch is operated, the call quality deteriorates in accordance with a predetermined pattern after that, so if the communication is disconnected repeatedly by the same pattern, the other party will be intentionally disconnected. It is assumed that there is, and it may be a factor that worsens interpersonal relations.

  In view of the above-described problems, the present invention can more naturally produce a deterioration in call quality when disconnecting an incoming call from an unfavorable partner, and can disconnect the call without assuming that the other party is intentionally disconnected. It is to provide a means to make.

  In the mobile terminal used for mobile communication, when an incoming call from an unfavorable partner is performed, when the user ends the communication by controlling transmission power in stages and finally ends the communication, By providing a means to enable this transmission power control pattern to be manipulated arbitrarily, the caller refuses to think that the communication was intentionally interrupted and does not interfere with future interpersonal relationships. It is characterized by doing so.

  Specifically, the mobile terminal having the telephone function of the present invention has a certain level of radio transmission power during the call transmitted from the mobile terminal each time a specific key switch is pressed during an incoming call or during a call. Transmission power control means for decreasing each of them is provided, and the call can be disconnected by the transmission power control means.

  In addition, the mobile terminal having a telephone function according to another embodiment of the present invention, when a specific key switch is pressed during an incoming call or during a call, Transmission power control means for transmitting a TPC command instructing a decrease in transmission power output from the base station is provided, and the call can be disconnected by the transmission power control means.

  The mobile terminal having a telephone function according to the present invention includes a means for storing a telephone number of a call partner disconnected by the transmission power control means, and a call impossible message when an incoming call is received from the telephone number stored in the storage means. It is possible to adopt a configuration provided with means for notifying the user of the call and disconnecting the call.

  In the present invention, the transmission power of the mobile terminal is controlled by the user, and the communication can be naturally cut off by implying to the caller that the user who received the incoming call is not capable of sufficient communication. Communication can be terminated without the other party's intentional disconnection.

  According to the present invention, when the user gradually decreases the transmission power of the mobile terminal, the transmission power control pattern can be varied for each incoming call by directly adjusting the transmission power control pattern according to the situation. Therefore, it is possible to terminate and terminate the call without the caller being aware that the user is intentionally terminating the call.

A first housing 2 provided with a microphone (transmitter) 5 and a key switch group 7 is configured to be foldable by a hinge portion 3.

  The key switch group 7 generally includes an on-hook key, an off-hook key, number keys (0) to (9), an asterisk (*) key, a sharp (#) key, a power key, a mode key, a clear key, and the like. However, in addition to these keys, the cellular phone according to the present embodiment is provided with function keys 7f for executing the operation of the present invention as independent keys or used as existing keys.

  FIG. 2 shows an example of a circuit block configuration of the mobile phone shown in FIG. In FIG. 2, the control unit 13 controls the execution of various functions included in the mobile phone according to the control program stored in the storage unit 16 and instructions from the operation unit including the key switch group 7. The control directly related to the present invention has a function of detecting the pressing of the function key 7f during a call and sending a control signal to be described later to the wireless processing unit 12 every time the function key 7f is pressed.

  The radio processing unit 12 has a function of performing radio transmission / reception such as a telephone call via the base station via the antenna 11 and measuring signal reception quality from the base station and receiving notification information of the base station. Yes. The voice processing unit 14, the speaker (receiver) 18, the microphone (transmitter) 19, the display unit 17 and the like execute normal functions provided in the mobile phone. Although not shown in the figure, a battery as an operation power supply, an incoming call notification means, and the like are also included.

  FIG. 3 shows an example of a mobile phone system to which this embodiment can be applied. A radio network controller (hereinafter referred to as RNC (Radio Network Controller)) and a radio base station apparatus (hereinafter referred to as Node-) belonging to the RNC. B).

Usually, transmission power from a mobile terminal is controlled in accordance with an SIR (Signal To Interference Ratio) of a pilot signal transmitted from a mobile terminal such as a mobile phone. That is, when the Node-B measures that the SIR of the pilot signal transmitted from the mobile terminal is better than a predetermined value, the Node-B instructs the mobile terminal to decrease the transmission power.
Send a Power Control command. When Node-B measures that the SIR of the pilot signal transmitted from the mobile terminal is worse than a predetermined value, Node-B transmits a TPC command instructing the mobile terminal to increase transmission power.

  On the other hand, the transmission power from Node-B is controlled corresponding to the SIR of the pilot signal transmitted from Node-B. That is, when the mobile terminal measures that the SIR of the pilot signal transmitted from Node-B is better than a predetermined value, the mobile terminal transmits a TPC command instructing Node-B to reduce transmission power. When the mobile terminal measures that the SIR of the pilot signal transmitted by Node-B is worse than a predetermined value, the mobile terminal transmits a TPC command instructing Node-B to increase transmission power.

  FIG. 4 is an operation flowchart of the mobile terminal showing the embodiment of the present invention. The operation of this embodiment will be described below with reference to FIG.

  When there is an incoming call to the mobile terminal (S100), the user confirms the caller from the incoming call notification, and when the incoming call is from an unfavorable party for the user, the function key 7f is first pressed (S101, Yes) and then the call is made. Start (S102). When the control unit 13 of the mobile terminal detects that the function key 7f is pressed, the control unit 13 ignores the TPC command from the Node-B and controls the radio processing unit 12 to keep the transmission output from the radio processing unit 12 constant. The level is lowered (S103). If the radio link between the Node-B and the mobile terminal is out of synchronization as a result of the transmission output being reduced by a certain level in S103 (S104, Yes), the line is automatically disconnected and the call is terminated (S105). .

  Even if the transmission output is lowered by a certain level in S103, if the call can be made without any loss of synchronization of the radio link between the Node-B and the mobile terminal (S104, No), the user again presses the function key 7f after an arbitrary time. When is pressed (S106, Yes), the control unit 13 controls the wireless processing unit 12 to further reduce the transmission output from the wireless processing unit 12 by a certain level (S103). By repeating the above operation until the radio link between the Node-B and the mobile terminal is out of synchronization, the line is finally automatically disconnected and the call can be terminated (S105).

  In addition, even if the call is started (S107) without answering the function key 7f without pressing the function key 7f without unavoidable or confirming the caller and the call is started (S107), the function key 7f can be used during the call. When the button is pressed (S108, Yes), the function of the present embodiment is enabled, and the operation can be shifted to the operation after S103. Therefore, the user can reduce the transmission output level from the wireless processing unit 12 by an appropriate pattern. It is possible to terminate the call by disconnecting the line (S105).

  According to this embodiment, since the user can arbitrarily control the transmission power transmitted from the mobile terminal to the base station manually, it is possible to produce more naturally until the end of the call, and intentionally disconnect the call to the other party It is possible to end the communication without seemingly.

  In the above embodiment, the dedicated function key 7f for reducing the transmission output during a call is provided, and the radio transmission output level from the mobile terminal is lowered by a certain level each time the function key 7f is pressed. However, the number keys (0) to (9) provided in the mobile terminal as a mobile phone are also used as keys for wireless transmission output control. For example, when the number (9) key is pressed at the time of incoming call response, When the number (8) key is pressed, the transmission power of the mobile terminal is further restricted, and the number (7) key, number (6) key,. Each time the key is pressed, the transmission power of the mobile terminal is sequentially reduced at an arbitrary rate, and finally the line is disconnected. Alternatively, for example, the function of the function key 7f is also used for the number (1) key. During a call, every time the user presses the number (1) key, the wireless transmission output level from the mobile terminal is lowered by a predetermined level, and finally it is also possible to employ a method in which the line is disconnected.

  FIG. 5 is an operation flowchart of a mobile terminal according to another embodiment of the present invention. In the embodiment shown in FIG. 4, the control unit 13 directly regulates the transmission power output from the radio processing unit 12 of the mobile terminal. However, in this embodiment, the control unit 13 uses the power transmitted from the Node-B to the mobile terminal. The method of regulation is adopted.

  As described above, normally, transmission power from Node-B is controlled in accordance with SIR of a pilot signal transmitted from Node-B. That is, when the mobile terminal measures that the SIR of the pilot signal transmitted from Node-B is better than a predetermined value, the mobile terminal transmits a TPC command instructing Node-B to reduce transmission power. When the mobile terminal measures that the SIR of the pilot signal transmitted by Node-B is worse than a predetermined value, the mobile terminal transmits a TPC command instructing Node-B to increase transmission power.

  Therefore, in the present embodiment, when the user presses the function button 7f before answering an incoming call or after the incoming call and enables this function, the control unit 13 of the mobile terminal causes the Node to be independent of the above power control method. -Send a TPC command to reduce the transmission power from B. While transmission of this TPC command is repeated, the synchronization of the radio link between the Node-B and the mobile terminal is finally lost, the line is disconnected, and the call ends. The operation of this embodiment will be described below with reference to FIG.

  When there is an incoming call to the mobile terminal (S200), the user confirms the caller from the incoming call notification, and when the incoming call is not desirable for the user, the user first presses the function key 7f (S201, Yes) and then makes a call. Start (S202). When the control unit 13 of the mobile terminal detects that the function key 7f is pressed, the TPC command for instructing the Node-B to reduce the transmission power output from the Node-B is sent via the radio processing unit 12. (S203). If the Node-B that has received this TPC command reduces the transmission power to the mobile terminal by a predetermined level and the radio link between the Node-B and the mobile terminal is out of synchronization (S204, Yes), the line is automatically The call is terminated and the call ends (S205).

  On the other hand, when the Node-B can reduce the transmission power to the mobile terminal by a predetermined level and can make a call without causing a synchronization loss of the radio link between the Node-B and the mobile terminal (S204, No), When the function key 7f is pressed again after an arbitrary time (S206, Yes), the control unit 13 again sends a TPC command for instructing the Node-B to reduce the transmission power output from the Node-B, to the wireless processing unit. 12 is transmitted (S203). By repeating the above operation until the synchronization of the radio link between the Node-B and the mobile terminal is lost, the line is finally automatically disconnected and the call can be terminated (S205).

  In addition, even when the call is started (S207) without unavoidably or without confirming the caller without pressing the function key 7f (No in S201) and the call is started (S207), the function key 7f is displayed during the call. When is pressed (S208, Yes), the function of the present embodiment is enabled and the operation can be shifted to the operation after S203, so that the line can be disconnected and the call can be terminated (S205).

  In the present embodiment, the number keys (0) to (9) provided in the mobile terminal as the mobile phone are replaced by the Node-B instead of providing the dedicated function key 7f on the mobile terminal. It can also be used as a transmission instruction key for a TPC command for instructing a reduction in output transmission power. For example, a TPC command for lowering transmission power depending on which of the number keys (0) to (9) is pressed. Is output from Node-B every time the number (1) key is pressed at the time of an incoming call or during a call, for example, by making the number (1) key also function as the function key 7f. By transmitting a TPC command instructing a decrease in transmission power, a method of finally disconnecting a line can be employed.

  Therefore, also in this embodiment, since the user can arbitrarily control the transmission power transmitted manually from the Node-B to the mobile terminal, it is possible to produce a more natural process until the end of the call, and intentionally calling the other party. It is possible to end the communication without seeming to have disconnected.

  If the call is disconnected in this way, the caller assumes that the other party's mobile terminal has moved to an area with a poor radio wave environment, and it is predicted that the call will be sent again after a while. If the other party's telephone number is memorized, and there is a re-incoming call from the memorized other party number, a message indicating that the mobile terminal cannot be connected because it is currently in an area where radio waves do not reach is transmitted. By notifying the person's mobile terminal and performing the call disconnection process, it is possible to reject the re-call from the partner without giving a bad impression.
