Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication method and a mobile information terminal for performing personal computer communication using a digital mobile phone network.

[0002]

2. Description of the Related Art Conventionally, there is a "direct number" method as an incoming call method using a digital mobile phone network. This "direct number" method gives an additional number to a mobile device such as a mobile phone in addition to its subscriber number.
This is a method of directly receiving an incoming call to a terminal such as a personal computer connected to a mobile phone using an additional number (“NTT DoC
oMo Technical Journal VOL3 No.
1), "New services for mobile communication networks, 3 Incoming services," pp 18-23).

That is, when the caller makes a call to the additional number, the exchange recognizes that the number is an additional number, and the subscriber number corresponding to the additional number is read from the table. Then, the subscriber number and the additional number are transmitted to the mobile device, the mobile device having the subscriber number first receives the incoming call, the mobile device receives the additional number sent subsequently, and the additional number is transmitted to the mobile device. By sending to a terminal such as a connected PC, it will be possible to automatically connect to Pacoson.

In the above-mentioned conventional technique, the communication software is activated in advance to set the automatic incoming call state, and then the incoming call is received.
The communication software starts communication according to the additional number at the time of incoming call.

[0005]

In the above-mentioned conventional direct number method, it is necessary to activate communication software for data communication or FAX communication in advance, and it is possible to use the additional number to automatically receive an incoming call. However, only an automatic incoming call of either data communication or FAX communication is possible. Therefore, for example, when the communication software for data communication is activated, if the other party uses the additional number to perform the FAX communication, there is a problem that the communication cannot be normally performed.

An object of the present invention is to discriminate whether the incoming call is a data incoming call or a fax incoming call based on the additional number, and activate the communication software in accordance with the result of the decision so that either the data communication or the fax communication can be performed. It is to provide a communication method and a mobile information terminal that enable communication.

[0007]

In order to achieve the above object, according to the present invention, a subscriber number and an additional number are assigned to a mobile phone and an information processing apparatus connected to the mobile phone, and The subscriber number is added to the additional number to be sent and sent, and the call is received by the mobile phone of the subscriber number.
Next, based on the received additional number, in the communication method of receiving an incoming call to the information processing device connected to the mobile phone and communicating between the information processing device and the terminal, It is characterized in that a predetermined communication software in the information processing device is started up by comparing with a registered number and if the numbers match.

Further, a plurality of numbers are registered in a portable information terminal equipped with a mobile phone, an information processing device in which a plurality of communication software is installed, and a communication adapter for connecting the mobile phone and the information processing device. Means for comparing the received additional number with the registered number when the mobile phone receives the subscriber number and the additional number from another terminal, and when the result of the comparison indicates that the registration And means for activating communication software corresponding to the selected number.

Time passes from top to bottom of the figure.

First, when the mobile phone 101 receives an incoming call from the other party, it outputs an incoming call notification 301 to the communication adapter 102. The communication adapter 102 waits for a called number notification (subscriber number) + dial (additional number) + dial completion (completion code) 302 for a predetermined time (T1) from the time when the incoming call notification 301 is received. Called party number notification within a fixed time (T1) +
When the dial + dial completion 302 is received ((a) in FIG. 3), the microcomputer 202 in the communication adapter 102 reads the additional number (registration number) registered in the RAM because it is the “direct number”. Then, this registration number is compared with the input dial (additional number), and when they match, the RING result 303 is called to the personal computer 103 at regular intervals (for example, 3 to call the personal computer).
Every second), and if they do not match, RING result 3
03 is not output.

Since the personal computer 103 is set to activate the communication software by detecting the RING result and automatically respond, the RING result 303 is set.
