Abstract

PURPOSE:To ensure the connection of both telephones and packets in any place where the radio transmission/reception is possible to an IPT (portable information terminal) by using the IPT that has a composite constitution including the radio connection, telephone and data communication functions respectively. CONSTITUTION:A data base device 10 retrieves a terminal attribute table to acquire the position information that is used as the routing information in an ISDN network in response to the number used in a general connection mode of the ISDN network of the incoming IPT. Then the device 10 decides that the connection of calls is possible based on the connecting conditions and also decides that the connection is possible by the position information only and by the display of calls to return the position information to an ISDN switchboard 3 of the transmitter side. The switchboard 3 sets an incoming IPT terminal number between a circuit 37 and an ISDN switchboard 7 of the receiver side based on the returned connection number and also transmits the IPT terminal number. The switchboard 7 decides the IPT connection and sets a circuit 78 and a radio circuit by the procedure set to an incoming IPT terminal 9. Thus a circuit is set between an outgoing IPT terminal 1 and the terminal 19 to ensure the talking between them.

FIG. 2 is an explanatory diagram of the operation of the system. The operation will be described below with reference to FIGS.

First, a call connection between IPTs will be described. When the originating IPT terminal 1 originates a call, the line 23 between the base station 2 and the originating ISDN exchange 3 is set by a predetermined procedure, and the originating IPT terminal 1 receives the incoming IPT number (OAO-222222) designated by the originator. A call instruction display is sent to the originating ISDN exchange 3. When the originating ISDN exchange 3 identifies that the received connection number is an IPT connection, the originating ISDN exchange 3 informs the database device 10 of the incoming IPT terminal number (O
AO-222222) and call display is sent.

In the database device 10, the terminal attribute table is searched, and the position information (03-3929-7552) corresponding to the number of the incoming IPT terminal at the time of general connection in the ISDN network and used as the routing information in the network (03-3929-7552) In addition, it is determined that the call connection is possible based on the connection conditions (in this example, only the call is made on Saturday and Sunday), and it is determined from the call display that the call can be made only by the position information. The position information is returned to.

In the originating ISDN exchange 3, the line 37 is set up between the destination ISDN exchange 7 and the incoming IPT terminal in the same manner as general line setup based on the returned connection number (03-3929-7552). Transfer the number.
The destination ISDN exchange 7 determines that the IPT connection is based on the incoming IPT terminal number, and sets the line 78 and the wireless line according to the procedure determined with the incoming IPT terminal 9. With the above operation, the originating IPT terminal 1 and the terminating IPT
A line is set up with the terminal 9 and communication becomes possible. At the end of the call, the line between both terminals is opened by the normal procedure.

Next, the case of packet communication will be described. When the originating IPT terminal 1 originates a call, the line 23 between the base station 2 and the originating ISDN exchange 3 is set by a predetermined procedure, and the originating IPT terminal 1 receives the incoming call I designated by the originator.
The PT number (OAO-222222) and the packet instruction display are sent to the originating ISDN exchange 3. When the originating ISDN exchange 3 identifies that the received connection number is the IPT connection, it sends the incoming TPT terminal number (OAO-222222) and the packet instruction display to the database device 10.

The database device 10 searches the terminal attribute table for position information of the terminating IPT terminal, determines from the packet indication that the designated terminating IPT terminal has a packet function, and determines the connection condition ( In this example, it is determined that the packet connection is possible on Saturday and Sunday, and only the call is made and the call origination is on Monday, and the packet switching device corresponding to the position information in the packet network from the position information is determined using the connection exchange number table 102. Connection number 666
666 is obtained and the connection number is returned to the originating ISDN exchange 3.

In the originating ISDN exchange 3, the destination ISDN exchange 7 is passed through the packetizing device 4, the packet exchange 5, and the packet converting device 6 based on the general ISDN packet connection procedure based on the returned connection number (666666). Incoming IP as well as setting packet channel between
The T terminal number OAO-222222 is transferred to the destination ISDN exchange 7. The destination ISDN exchange 7 determines that the IPT connection is based on the incoming IPT terminal number, and the incoming
The line 78 and the wireless line are set by the procedure determined with the PT terminal 9. With the above operation, a line is set up between the originating IPT terminal 1 and the terminating IPT terminal 9 and communication becomes possible. At the end of communication, the line between both terminals is released by the normal procedure.

Although the above embodiments have described the use of the IPT terminal, the destination side is not limited to the IPT, and communication with general packet terminals or data communication centers accommodated in the packet network also requires the connection number assigned to them. It is self-evident that the originating IPT terminal can dial.

[0017]

As described above, according to the present invention,
By using a mobile information terminal, there are no restrictions on the location of data communication such as telephone calls and packet communication, and such communication is possible not only in fixed locations, but also in any location. It will be available anytime, anywhere, and will contribute to the vitalization of society.
