[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a call-restricted wireless communication apparatus according to the present invention. As shown in FIG. 1, the call-restricted wireless communication device of the present invention includes an input device 4 such as a keyboard, a program unit 3 having a function of operating under program control and storing information, and displaying and sounding information. Includes a display unit 5, a wireless unit 1 for performing communication, a voice unit 2 for handling voice of a call, a microphone 7 and a speaker 8 for transmitting and receiving voice, and an antenna 6 for transmitting and receiving radio waves for communication. .

When the call-restricted wireless communication device of the present invention is used for transmission, a user inputs a telephone number of a transmission destination and a transmission command using the keyboard of the input device 4. Then, the input result is displayed on the display unit 5 via the program unit 3, output to the wireless unit 1, and further transmitted from the antenna 6 to the base station. After the communication channel is established, the voice of the user is modulated from the audio unit 2 via the microphone 7 by the radio unit 1 and transmitted from the antenna 6 to reach the base station.

On the other hand, when the call-restricted wireless communication apparatus of the present invention is used for reception, a radio wave from a base station is received by an antenna 6 and demodulated by a radio unit 1, and then the received voice signal is transmitted from a voice unit 2 to a speaker 8. The received data signal is displayed on the display unit 5 via the program unit 3.

The above-described call-restricted radio communication apparatus of the present invention has a transmitting / receiving function and a standby function, a receiving level detecting function, a function of judging the receiving level in a stepwise manner, and a bar graph or the like showing the determined level. And a function for selecting a reception level at which the user can make a call.

Specifically, when the user turns on the wireless device and is in a standby state in which both outgoing and incoming calls are possible,
The user selects in advance a reception level stage that enables a call and stores it in the wireless device.

When an incoming call is received, the wireless device does not sound a ring tone when the reception level is lower than the reception level set by the user in advance, and returns a call rejection state to the wireless base station. Also responds to the incoming call by answering machine.

When the user performs an outgoing call operation, the user is informed of the call restriction for a certain period of time. Nevertheless, when the user desires a call and performs an operation such as pressing a specific key, the user performs a calling operation, and otherwise returns to a standby state.

In the standby state, the reception level is
If it is less than the user's setting stage, it is displayed that it is out of the communicable area, and the out-of-service operation starts to judge whether the area is in the communicable area at a longer interval than during normal standby.

FIG. 2 shows an example of the display of the reception level. That is, the radio unit 1 sends the level data of the radio wave received from the base station to the program unit 3, the program unit 3 determines the level of the reception level, and causes the display unit 5 to display the level data. In FIG. 2, the reception level is displayed in a bar graph in four stages. As shown in FIG. 2, there are four levels of 0, 1, 2, and 3 in the order of lower reception level. The reception level whose stage is 0 is from zero to the first
The reception level which is lower than the predetermined value and whose level is 1 is a level which is higher than the first predetermined level and lower than the second predetermined level. Hereinafter, the same applies. Further, the reception level “0”
Is a threshold value level for judging whether the terminal is in or out of service as in the related art without executing the call restriction function. Referring to this display, the user sets a threshold value for call restriction. When the threshold value is set, a predetermined command, for example, “FXX” is input from the keyboard, and another command is input. To cancel the setting, use “FX
Input another command after "X".

FIG. 3 is a diagram showing a display example of the display unit 5 according to each state of transmission, reception and standby. (A) is a display example at the time of standby (no call restriction setting).
(B) is a display example at the time of user setting (current state).
(C) is a display example at the time of a call operation (no call restriction setting). (D) is a display example at the time of an incoming call (no call restriction setting). (E) is a display example at the time of out-of-service operation (no call restriction setting). (F) is a display example at the time of standby (call restriction setting). (G) is a display example after user setting. (H) is for outgoing calls (call restriction
This is a display example of “setting is performed”. (I) is a display example at the time of an incoming call (call restriction setting). (J) is a display example at the time of out-of-service operation (call restriction setting).

FIG. 4 is a flowchart for explaining the operation of the call-restricted wireless communication device according to the present invention. As shown in FIG. 4, when the user presses the power key of the input device 4 of the wireless device, the initializing step 20 of the program unit 3 is started.
2 to determine the state of the wireless device, and branch to processing corresponding to the state (step 203).

First, the operation of "setting call restriction by key input" shown in the flowchart will be described. When a command for setting or canceling the call restriction, for example, “FXX” is input by the user, the reception level is detected by the program unit, and the reception level is displayed on the display unit (step 216). The user refers to the reception level and inputs another predetermined command to select and specify a reception level step serving as a threshold for call restriction (215). The threshold value that has been set at the present time is “3” as illustrated in FIG. The user can change this threshold to “2” as illustrated in FIG. The set threshold value is displayed on the display unit 5 using a marker or the like, and is stored in the reception level storage unit of the program unit 3 (229). Next, the process returns to the state judgment / branch step 203. If call restriction is not desired, another predetermined command for canceling the previous setting is input. As a result, only the reception level "0" is recorded in the reception stage storage unit of the program unit, and the state can be shifted to the normal transmission / reception state (step 230).

Next, the operation of "normal standby" shown in the flowchart will be described. During the normal standby, the user is in a standby state without setting “call restriction”. In this state, first, the reception level is determined (step 211), and the reception level is “0”.
In the above case, the operation during normal standby (step 22)
While performing 1), as shown in FIG.
The time is displayed, and the process returns to the state determination / branch step 203. On the other hand, in step 211, the reception level is “0”.
If it is less than the above, the process moves to the out-of-service operation step 222, and the fact that the out-of-service operation is being performed is displayed as shown in FIG. That is, as shown in FIG. 4 (e), in addition to the date, the day of the week, and the time, the character "out of service" is displayed on the display unit 5. In this way, it is displayed that the operation is out of service, and the process returns to the state determination / branch step 203 again.

Next, the "transmission operation by key input" shown in the flowchart will be described. In this case,
First, the reception level is determined (step 212), and when the reception level is equal to or higher than the set stage, the display of the transmission operation is performed. This display is, for example, as shown in FIG. 3 (h), with the message "Iroha" and the other party's telephone number "04".
512137456 "and the reception level stage" 2 "which has been set as the threshold value at the present time are displayed. On the other hand, if the reception level is lower than the setting stage, it is determined whether or not to continue the transmission (step 224). This determination is made by the user based on the urgency of transmission. If the continuation of the transmission is selected in the determination step, the setting of the reception level for performing the call restriction is canceled by the program section 3, and the operation shifts to the normal transmission operation (step 223). On the other hand, if the cancellation of the transmission is selected, a display of normal waiting is displayed, and the process returns to the state determination / branch step 203. Here, the continuation or suspension is performed by a user inputting a predetermined command by a key.

Next, the operation of "receiving a call" shown in the flowchart will be described. Here, first, the reception level is determined (step 213). If the reception level is equal to or higher than the setting stage, the reception operation is displayed. In this display, as shown in FIG. 3 (i), "incoming call" indicating that there is an incoming call, the other party's telephone number "0398765432", and a reception level step "2" which is a threshold for call restriction are displayed. You.
When the call restriction is not set, the threshold value is “0”, and the threshold value “0” does not have to be displayed as illustrated in FIG. On the other hand, if the reception level is lower than the setting level, it indicates that there is an incoming call and transmits a call rejection to the base station (step 226).

Next, "out of service area" shown in the flowchart will be described. Here, first, the reception level at that time is determined (step 214). If the reception level is equal to or higher than the set level, the display is switched during normal standby (step 227), and the state determination / branch step 203 is performed. Return. On the other hand, when the reception level is lower than the setting stage, the display of the out-of-service operation is continued and the state judgment /
The process returns to the branching step 203. Here, as shown in FIG. 3 (j), the display of the out-of-service operation includes date, day of week, time,
In addition to the setting level “2”, “out of service” indicating that the user is out of the service area of the wireless communication is displayed.

Although one embodiment of the present invention has been described above, the present invention relates to a system for making a call via a base station like a wireless device, that is, a so-called mobile phone or a normal one-to-one communication. The present invention can be applied to a wireless device such as a commercial wireless device.

[0030]

According to the present invention described above, the first effect is to provide a function that allows the user to set an arbitrary reception level so that the user can receive an incoming call when he does not want to receive the incoming call. Not to bother the user.

The second effect is that by providing a function that allows the user to set an arbitrary reception level,
It is an object of the present invention to prevent a call quality from deteriorating near a reception level at which a call is limited, avoiding an unclear call, and enabling a stable call.

The third effect is that by providing a function that allows the user to set an arbitrary reception level,
In the standby state, the wireless device performs “out-of-service operation” when the reception level is lower than the set reception level. Therefore, as the user sets a higher reception level, the frequency (time) of performing “out-of-service operation” increases. It is possible to reduce the battery consumption of the device.
