[0002]
[Prior art]
As a result of integrated circuit technology development and extensive research by telephone engineers, various functions that are very useful for telephones are being added day by day. As one of the functions, a function that uses the number display service to ring a ringing tone such as voice or melody registered in advance by the number of the other party who called the cordless telephone is known. ing. According to this function, when an incoming call is received, it can be instantly determined from who or to whom the call is directed according to the type of ringing tone. For example, if the ringtone is "Melody 1", it will be from friend A. If the ringtone is "Melody 6", it will be from friend B. If the ringtone is "Otosan, phone", the call will be sent to your father. If the call is “Onee-chan, I ’m on the phone,” it ’s a phone call to my sister.
[0003]
[Problems to be solved by the invention]
However, in the case of using the above function, in the prior art, it is necessary to register a voice or a melody ringing tone for each telephone number of the other party in the base unit and the handset of the cordless telephone, which is very troublesome. In order to prevent confusion on the part of the listener in particular, when the same ringing tone is set for the main unit and the slave unit, the ringing tone must be set for the main unit and the slave unit even though the ringing tone is the same. Is very annoying.
[0004]
The present invention has been made in view of the above points, and an object of the present invention is to provide a cordless telephone in which the setting of the handset becomes very simple.
[0005]
[Means for Solving the Problems]
The cordless telephone of the present invention is configured to turn on or off the setting of the ringing tone type corresponding to the other party's telephone number in the base unit and the setting of “same ringing tone as the base unit” in the handset. When the incoming call is received, if the ringing tone corresponding to the other party's telephone number is ringed in the parent unit and the “same ringing tone as the parent unit” setting is turned on, And a means for ringing the same ringing tone as the handset by the handset.
[0006]
In this cordless telephone, the operation in which the handset rings with the same ringing tone as the base unit can be made possible with a specific type of ringing tone. The particular type of ring tone can be a voice call and / or a melody. Further, the operation in which the slave unit rings with the same ringing tone as that of the master unit can make all the ringing sounds the same as those of the master unit. When there are a plurality of slave units, the “same ringing tone as the master unit” setting can be turned on / off individually for each slave unit. In addition, in order to cause the child machine to ring with the same ringing sound as the parent machine, the parent machine first sends the “same call command” to the child machine, and then sends the same ringing tone signal from the parent machine to the child machine. When the machine receives the “same call command” from the parent machine, it sets a speech path in order to ring the ringing tone using the same ringing sound signal from the parent machine.

Therefore, when receiving the incoming call, if the telephone number of the other party is found by the number display service, the base unit 10 rings with a ringing tone corresponding to the telephone number if the telephone number is registered in the telephone directory.
[0012]
On the other hand, in the handset 30, when the “same ringing sound as the base unit” setting is turned on, the base unit 10 registers the voice calls of 11 to 17 even if there is no registration in the phone book of the memory 40. If there is an incoming call, it rings with the same ringing tone (voice call) as the base unit 10. These operations will be described in detail below.
[0013]
First, an operation for registering the name, telephone number and ringing tone of the other party in the telephone book of the base unit 10 will be described with reference to FIG. FIG. 5 shows a screen display example of the LCD display unit 13. In the case of phone book registration, first, the key input unit 12 of the parent device 10 in the standby state is operated to set the parent device 10 to the phone book registration mode. Then, the screen of the LCD display unit 13 is switched from the standby screen of the screen G1 to the screen G2, "Namae?" Is displayed, and the other party's name can be input. Therefore, the name of the other party, for example, “Kenwood” is input using the character keys of the key input unit 12 as shown on the screen G3. Next, when the function key of the key input unit 12 is operated, the screen of the LCD display unit 13 is changed to the screen G4, “Bangou 1?” Is displayed, and the first telephone number can be input. Therefore, the first telephone number, for example, “01234567” is input using the numeric keys of the key input unit 12 as shown on the screen G5. Next, when the function key is operated again, the screen of the LCD display section 13 becomes the screen G6, “Bangou 2?” Is displayed, and the second telephone number can be input. Therefore, the second telephone number, for example, “0987654” is input using the numeric keys of the key input unit 12 as shown on the screen G7. In this way, two telephone numbers can be entered for one opponent.
[0014]
After that, when the telephone book key of the key input unit 12 is operated, the screen of the LCD display unit 13 is changed to the screen G8, “Yobidashi Kino: Select” is displayed, and the selection mode of the ringing tone is set. In this state, the up key and the down key of the key input unit 12 are operated to select any one of the ringing sounds 1 to 17 described above. At this time, each time the ringing tone from 1 to 17 is switched, the ringing tone sounds for confirmation. Thereafter, by operating the function keys, the screen of the LCD display unit 13 is changed to the screen G9, the registered name and telephone number of the other party are displayed, and an operation confirmation sound is generated at the same time. Return to state. As described above, as an example, 100 names, the name and telephone number of the other party, and the ringing tone can be registered in the telephone directory.
[0015]
Next, the operation of turning on / off the setting of “same ringing sound as the parent device” in the child device 30 will be described with reference to FIG. 6 (which is a screen display example of the LCD display unit 39 as in FIG. 5). In this case, first, the function key of the key input unit 38 is operated to switch the slave unit 30 from the standby state to the menu mode. Then, the screen of the LCD display unit 39 is changed from the standby display of the screen G11 to the menu display of the screen G12 (the screen G12 is a part of the menu display), and “1: Replaying a message” “2: Clearing a message”. “3: Initial setting” is displayed. Here, “3: initial setting” is selected using the numeric keys of the key input unit 38. Then, the screen of the LCD display unit 39 is an initial setting menu display of the screens G13 and G14 (the screens G13 and G14 are part of the initial setting menu display, and the screens G13 and G14 are switched or scrolled with the up / down keys). “6: I am also a call” is displayed along with “1: Recital number”, “2: Automatic absence”, and the like. Here, “6: I am also a call” means “same ringing sound as the parent device”, and then, “6: I am also a call” is selected using the numeric keys.
[0016]
Then, the screen of the LCD display unit 39 becomes a screen G15, “1: ON, 2: OFF” is displayed, and it is asked whether “I also call” is set (ON) or not set (OFF). come. Here, operating the number key “0” turns off “Me call”, and operating the number key “1” turns on “me call”. Therefore, the number key “1” is operated to select “1: ON”, and “I am also a call” (same ringing tone as the parent device) is set. After that, when the function key is operated, the screen of the LCD display unit 39 becomes the screen G16, “I also set the call” is displayed, and at the same time, an operation confirmation sound sounds, and after a predetermined time, the screen returns to the standby state of the screen G11. .
[0017]
When “same ringing tone as the parent device” is set in the child device 30 in this way, a signal to that effect is transmitted from the child device 30 to the parent device 10 and stored in the memory 14 of the parent device 10. Therefore, when the base unit 10 rings with a ringing tone corresponding to the other party's telephone number when an incoming call is received, the same ringing tone signal is transmitted from the base unit 10 to the handset 30, and the telephone number and the ringing tone are transmitted to the handset 30. Even if there is no registration, handset 30 rings with the same ringing tone as base unit 10. However, in this example, when the parent device 10 rings with the above-described voice calls of 11 to 17, the child device 30 rings with the same voice call. In other cases, even if the “same ringing tone as the parent device” is set, the ringing is performed by the unique ringing tone of the child device 30. Further, in order to set the same ringing tone, the base unit 10 first transmits the “same call command” to the handset 30, and subsequently created in the handset 30 by the voice synthesis recording / playback unit 29 of the base unit 10. A voice call ring signal is transmitted. On the other hand, when receiving the “same call command” from the parent device 10, the child device 30 sets a communication path in order to sound a ringing tone using a voice call calling sound signal from the parent device 10.
[0018]
When there are a plurality of slave units 30, the setting of “same ringing tone as the master unit” can be turned on / off for each slave unit. For example, a child device in a bedroom has the same ringing sound as the parent device, and a child device in a child room has a different ringing sound from the parent device.
[0019]
Hereinafter, the operation related to the ringing tone at the time of incoming call will be described in detail with reference to the flowchart of FIG. In the following description, there are a plurality of slave units. First, when there is an incoming call in the base unit 10 in step S1, the base unit 10 performs a match search in step S2 to see if the other party's telephone number obtained by the number display service is registered in its own phone book. If it is determined in step S3 that there is no registration and it does not match, the process proceeds to step S4, and both the parent device 10 and the child device 30 ring the normal electronic bell sound (simply indicated as “normal” in FIG. 1). Settings are made and the ringing tone is generated in step S5. When the handset's ring tone is “normal”, the other party's number data sent from the base unit to the handset is compared with the phone number registered in the handset's memory. Ring the corresponding ringer by yourself.
[0020]
On the other hand, if it is determined in step S3 that there is a registration, the process proceeds to step S6, where only the voice call is determined for the ringing tone registered corresponding to the telephone number. If it is determined in step S6 that the call is not a voice call, the process proceeds to step S7, where the master unit 10 sets a ringing tone other than the voice call and the slave unit 30 sets a ringing tone to a normal electronic bell tone. In step S5, the ringing tone is sounded.
[0021]
On the other hand, when it is determined in step S6 that the registered ringing tone is a voice call, the process proceeds to step S8, where it is determined whether or not there is a slave unit set to “same ringing tone as the parent unit”. If it is determined that there is no slave unit 30 set, the process proceeds to step S9, where the master unit 10 performs a voice call, and the slave unit 30 performs a normal electronic bell ringing tone setting. Ring the ringer.
[0022]
On the other hand, if it is determined in step S8 that there is a handset 30 that is set to “same ringing sound as the base unit”, the process proceeds to step S10, where the base unit 10 performs a voice call, and the set handset 30 is The same voice call as that of the base unit 10 and the other handset units 30 that are not set perform the ringing tone setting for a normal electronic bell sound, and ring the ringing tone in step S5.
[0023]
As described above, when the ringing tone is registered in the base unit 10 by voice call, the handset 30 can also be set as the same ringing tone. However, not only the voice call but also a melody is registered as the ringing tone, or The ringing tone of the handset 30 can be made the same as that of the base unit 10 for all ringing sounds including beep sounds. Also in this case, the base unit 10 stores that the handset 30 is set to “same ringing tone as the base unit”, and based on that, when receiving a call, first, the base unit 10 sends the “same call command” to the handset 30 Then, the same ringing tone signal is transmitted from the parent device 10 to the child device 30. On the other hand, when receiving the “same call command” from the base unit 10, the handset 30 sets a speech path in order to ring the same ringing tone with the same ringing tone signal from the base unit 10.
[0024]
FIG. 2 is a flowchart showing in detail the operation related to the ringing tone of the base unit 10 and the handset unit 30 at the time of incoming call when the same call is expanded to all ringing sounds. This operation will be described below. First, when there is an incoming call in the base unit 10 in step S21, the base unit 10 performs a match search in step S22 to check whether the other party's telephone number obtained by the number display service is registered in the own phone book. If it is determined in step S23 that there is no registration and it does not match, the process proceeds to step S24, and both the parent device 10 and the child device 30 ring the normal electronic bell sound (simply indicated as “normal” in FIG. 2). Settings are made and the ringing tone is generated in step S25.
[0025]
On the other hand, if it is determined in step S23 that there is a registration, the process proceeds to step S26, where only the voice call is determined as the ringing tone registered corresponding to the telephone number. If it is determined in step S26 that the call is not a voice call, the process proceeds to step S27 to set the base unit 10 to a registered ringing tone other than the voice call. Thereafter, the process proceeds to step S28, where it is determined whether or not there is a slave unit 30 that is set to “same ringing tone as the master unit”. If it is determined that there is no slave unit 30 that is set, the process proceeds to step S29. Then, the ringing sound of the handset 30 is set to a normal electronic bell sound, and then the process proceeds to step S25 to ring the base unit 10 and the handset 30 with the ringing sounds set in step S27 and step S29. .
[0026]
On the other hand, when it is determined in step S28 that there is a child device 30 set to “same ringing sound as parent device”, the process proceeds to step S30, where the set child device 30 has the same call as the parent device 10. The other handset 30 that is not set for sound (except for the voice call), sets the ringing tone to the normal electronic bell sound, and then moves to step S25 to set each call set in step S27 and step S30. The parent device 10 and the child device 30 are sounded by sound.
[0027]
On the other hand, when it is determined in step S26 that the registered ringing tone is a voice call, the process proceeds to step S31, where the master unit 10 is set to the registered voice call. Further, the process proceeds to step S32, where it is determined whether or not there is a slave unit 30 that is set to “same ringing sound as the master unit”. If it is determined that there is no set slave unit 30, the process proceeds to step S33. The ringing sound of the machine 30 is set to a normal electronic bell sound, and then the process proceeds to step S25, where the parent machine 10 and the child machine 30 are sounded by the ringing sounds set in steps S31 and S33.
[0028]
On the other hand, when it is determined in step S32 that there is a child device 30 set to “same ringing sound as parent device”, the process proceeds to step S34, where the set child device 30 has the same voice as the parent device 10. The other handset 30 that has not been called and set does the ringing setting for the normal electronic bell sound, and then moves to step S25, and the base unit 10 and the handset with each ringing sound set in step S31 and step S34. Ring 30.
When the same ringing tone as the master unit is set on the handset side, it is possible to set a speech path that amplifies the voice from the base unit. Needless to say, the ringing tone created in step 1 is amplified by the master unit and transmitted to the slave unit at the same time.
[0029]
【The invention's effect】
As described in detail above, according to the cordless telephone of the present invention, if the ring tone is registered in the base unit, the telephone number can be set one by one by simply turning on the “same ring tone as the base unit” setting in the base unit. Without registering the ringing tone, the ringing tone can be the same as that of the base unit for each telephone number of the other party. Therefore, setting on the slave unit becomes extremely simple, and usability is improved. If the registration of the master unit is used as described above, the number of registrations of the master unit + the number of registrations in the phone book of the slave unit becomes the apparent number of registrations of the slave unit. The number of cases can be increased.
