The present application is based on and claims priority of Japanese patent application No. 2004-363533 filed on Dec. 15, 2004, the entire contents of which are hereby incorporated by reference.
1. Field of the Invention
The present invention relates to a telephone communication system or a mail sending/receiving system using a wireless communication terminal, and specifically to a telephone communication system or a mail sending/receiving system which takes into account of the case where a wireless communication terminal is connected with a hands-free device.
2. Description of the Related Art
As a device for enabling a user to talk on the telephone without holding a cellular handset, there has been a hands-free device. Conventional arts relating to the hands-free device are disclosed by Japanese Patent Laid-Open Publication No. 2002-10358 (patent document 1), Japanese Patent Laid-Open Publication No. 2002-290537 (patent document 2) and the like.
It is assumed that a user uses a hands-free device of a cellular phone as the user cannot hold a handset of the cellular phone (this is why the user uses a hands-free device). Even in such a case, the user is usually doing something (such as driving a car), while talking on the phone. Although a user is relieved of holding or operating a handset of the cellular phone by using a hands-free device, the user is deprived of attention and concentration on the work the user is doing while talking on the phone. Accordingly, it is inappropriate for the user to talk on the phone while doing something (particularly while driving a car).
In such a case, the caller side cannot recognize whether the counterpart who the caller wants to make a phone call is using a hands-free device or not, in the conventional art. As the caller calls up (makes a phone call to) the counterpart whether or not the counterpart is using a hands-free device, a situation such as “talking on the phone while doing something” cannot be prevented or deterred from.
The present invention intends to provide a telephone communication system or a mail sending/receiving system for preventing or reducing the occurrence of the situation of talking on the phone by using a hands-free device (i.e., while doing something such as driving a car).

Specific embodiments of the present invention will be described with reference to the attached drawings. The embodiments below are merely examples for implementing the present invention and not intend to limit the present invention.
As shown in
With reference to
Now, an outline of operation relating to the present invention of the telephone communication system 1 of the embodiment will be described with reference to
If it is determined Yes (hands-free device 110 is connected) at step 302, the exchange 15 obtains information on the caller from the caller's home memory at step 303 and sends audio information such as “The counterpart's cellular phone is connected with a hands-free device. The user of the phone is possibly driving a car” (the audio information is recorded previously or processed and generated by a computer provided in the exchange 15.) to the caller (the cellular phone 11a or the fixed phone 12) at step 304. Then, the exchange 15 sends audio information such as “If you want to cancel this calling, press “0”, if you want to record a message in the answering phone service, press “1”, and if you want to talk with the counterpart, press “2”” (step 305), and waits for an operation directing signal (a push signal corresponding to “0”, “1” or “2” from the cellular phone 11a or the fixed telephone 12) (step 306). At step 307, the system determines the direction. If the direction is “0” (to cancel the calling), the system releases the connection between the exchange 15 and the cellular phone 11a or the fixed telephone 12. If the direction is “1” (to record a message in the answering service), the system records a message in the answering phone service. If the direction is “2” (to talk), operation proceeds to step 309 where talking on the phone is processed thereafter and the process ends.
Information sent to the caller at step 304 or step 305 can be sent by mail by obtaining the mail address when information on the caller is obtained at step 303, or by a Web page with an input form, instead of sending audio information as mentioned above. Although “cancel the calling”, “record a message in the answering service” and “talk” exemplify selections for the operation request in the above description, the present invention can be adapted to make one of the other types of process such as generating a message such as “You have a message “Mr. *** asks you to contact him as soon as possible”” or “You have a message “Mr. *** asks you to contact him when you are free”” by using the information on the caller (such as a name) obtained at step 303 and sending the message to the cellular phone 11 (called side), or informing that the hands-free device 110 is disconnected from the counterpart's cellular phone (cellular phone 11) (the exchange 15 or the like informs a calling person by a sound message or a piece of mail, when it is detected that the hands-free device is disconnected). In addition, although the embodiment is adapted to make selection of an operation request after the information such as “The counterpart's wireless communication device is connected with a hands-free device” is received, information on “operation direction in the hands-free state” can be previously added when the calling is made. By adding and sending the information on “operation direction in the hands-free state (for example, to cancel the calling when the counterpart is in the hands-free state)” previously at making the phone call, the process of step 304—step 306 in
As mentioned above, according to the telephone communication system 1 of the embodiment, information such as “The counterpart's wireless communication terminal is connected with a hands-free device” is sent to the caller before a connection between the wireless communication terminal and the caller side is established, and the caller who received the information can voluntarily cancel the calling before “talking on the phone” is performed. Even if a caller wants to talk on the phone over an urgent case, the caller tries to cut short the talking as the caller knows that the counterpart is in the hands-free state. Therefore, the present invention can prevent or reduce talking on the phone with a person using a hands-free device (i.e., while the person is doing something such as driving a car or the like). An operation directing signal indicating a request of the caller side in the case of “the counterpart's wireless communication terminal is connected with a hands-free device” (for example, to send a message such as “Contact us as soon as possible” or “Contact us when you are free” to the counterpart, or a calling request or a request for recording in the answering machine) is sent. According to the signal, the process such as sending a message or establishing a connection can be performed. This allows measures to be taken can be selected according to the emergency or the like, which is quite convenient for both the caller side and the called side.
If the cellular phone 11 is called when it is connected with the hands-free device 110, the present invention can be adapted to save information such as “this phone call is made with a hands-free device 110” as history information and display the history information on a display unit on the cellular phone 11 according to a display request or the like (an exemplary display screen is shown in
As shown in
As the outline of operation for detecting the “hands-free device connection state” of the cellular phone 11 in the embodiment is the same as that in the embodiment 1 (
Now, with reference to
If it is determined Yes at step 71 (if the cellular phone is connected with the hands-free device 110), the mail sending/receiving system 60 sends a piece of mail including contents such as “The counterpart's cellular phone is connected with a hands-free device. The user of the phone is possibly driving a car” and contents such as “If you want to cancel sending of the piece of mail, return a piece of mail with the subject “0”, if you want to send the piece of mail after the hands-free device is disconnected from the cellular phone, return a piece of mail with the subject “1”, and if you want to send the piece of mail immediately, return a piece of mail with the subject “2”” to the sender of the mail (address of the mail sender) at step 72 and waits for a return (mail) from the address of the mail sender (step 73). The system determines the direction at step 74 (determines according to the sender's address and the “subject”). If the direction is “0” (to cancel sending of the piece of mail), the system deletes the received piece of mail (without distributing the piece of mail to the cellular phone 11) and ends the process. If the direction is “1” (to send the piece of mail after the hands-free device is disconnected), the system waits for the hands-free device 110 to be disconnected at step 76, distributes the piece of mail after the hands-free device 110 is disconnected (step 77) and ends the process. If the direction is “2” (to send the piece of mail), operation proceeds to step 77 where the piece of mail is distributed and the process ends.
Sending of information to the mail sender and obtaining of the direction at step 72—step 74 can be performed by sending an address of a Web page or the like which contains an input form (a page for obtaining the direction) by mail instead of sending a piece of mail including a guidance and waiting for a return mail as mentioned above. As a selection for operation requests, the process such as generating a message (audio) such as “You have a message “Mr. *** asks you to contact him as soon as possible”” or “You have a message “Mr. *** asks you to contact him when you are free”” by using the information obtained by the abovementioned input form (such as a name) and sending the message to the cellular phone 11 (the base station 13 calls the cellular phone 11 and plays the sound message) can be added. In addition, although the embodiment is adapted to make selection of an operation request after the information such as “The counterpart's wireless communication device is connected with a hands-free device” is received, information on “operation direction in the hands-free state” can be previously added for sending when the piece of mail is sent.
As mentioned above, according to the mail sending/receiving system 60 of the embodiment, information such as “The counterpart's wireless communication terminal is connected with a hands-free device” is sent to a mail sender before a piece of mail is distributed to the cellular phone 11. Therefore, the mail sender who received the information can voluntarily cancel or prolong the “distribution of the piece of mail to the cellular phone 11” (until the hands-free device is disconnected) or send an audio message instead of a piece of mail. As the present invention can prevent or reduce distribution of a piece of mail to a cellular phone using a hands-free device when the cellular phone is using the hands-free device, it can prevent the called party's attention from deviated particularly when the called party is driving a car (checking the display screen of the cellular phone 11).
Although information sent from the cellular phone 11 to the base station 13 is “connection state of a hands-free device” in the embodiments, additional information such as “driving a car” or the like can be sent if a user of the cellular phone 11 sets as needed. Accordingly, in the process of
According to a telephone communication system of claim 1 of the present invention, comprising a wireless communication terminal, a base station for sending and receiving a signal to and from the wireless communication terminal via a wireless access network, an exchange connected with the base station, and a relaying network interconnecting the exchanges or an IP network connected via inter-network connecting devices, wherein when said wireless communication terminal is connected with a hands-free device, the wireless communication terminal sends information indicating that the wireless communication terminal is connected with said hands-free device to said base station, said exchange or a server provided in said IP network for saving the information; and when a phone call is made to the wireless communication terminal connected with said hands-free device, said base station, said exchange or said server sends information indicating that said called wireless communication terminal is connected with said hands-free device to the caller, that the information indicating that “the counterpart's wireless communication terminal is connected with a hands-free device” is sent to the caller (that the caller recognizes that the counterpart is using a hands-free device means that the caller can infer that the counterpart is in a state of driving a car or the like) so that the caller who received the information can voluntarily cancel the calling or cut short the talk, which prevents or reduces talking on the phone with a person using a hands-free device (i.e., while the person is doing something such as driving a car or the like).
According to the telephone communication system of claim 1 according to claim 2 of the present invention, when a phone call is made to the wireless communication terminal connected with said hands-free device, said base station, said exchange or said server sends information indicating that said wireless communication terminal of the called party is connected with said hands-free device to said caller before a connection between the wireless communication terminal and said caller is established, that the information indicating that “the counterpart's wireless communication terminal is connected with a hands-free device” is sent to the caller so that the caller before a connection between the wireless communication terminal and the caller side is established (i.e., before “talking on the phone” is performed) so that the caller can voluntarily cancel the calling before the “talking on the phone” is performed, which can prevent talking on the phone with a person using a hands-free device (i.e., while the person doing something such as driving a car). This also gives an additional effect of saving the circuit resource due to the reduction in the number of “connection settings”.
According to the telephone communication system of claim 1 or 2 according to claim 3 of the present invention, wherein at the time of said calling, said caller side sends an operation directing signal indicating a request of said caller in the case where said wireless communication terminal of the called party is connected with a hands-free device to said base station, said exchange or said server, or said caller side sends an operation directing signal indicating a request of said caller according to the state that said wireless communication terminal of the called party is connected with a hands-free device to said base station, said exchange or said server after it received information indicating that said wireless communication terminal of the called party is connected with said hands-free device from said base station, said exchange or said server; and said base station, said exchange or said server performs predetermined operation according to the operation directing signal, that the operation directing signal indicating a request in the case where “the counterpart's wireless communication terminal is connected with a hands-free device” (for example, sending a message “Contact us as soon as possible” or “Contact us when you are free” to the counterpart or a phone calling request) is sent to the base station, the exchange or the server, and process of sending a message or establishing a connection is performed, which can not only prevent talking on the phone with a person using a hands-free device but also allow measures to be taken according to the emergency or the like, which is quite convenient for both the caller side and the called side.
