Abstract

PROBLEM TO BE SOLVED: To perform communication in real time by converting information through a portable terminal data converting device with respect to communication between portable terminals which have different data formats and different communication systems. SOLUTION: When a portable terminal A11 communicates with a portable terminal B15, if the terminal A11 detects the mismatching of at least either a data format or a communication system, it disconnects a line, performs communication connection to a portable terminal data converting device 16 that is connected to an exchange 13 and transmits a signal which consists of a prescribed protocol, identifier, a sending address, a sub address, receiving address and a call setting class to a radio base station 12. When the station 12 transmits to the device 16 through the exchange 13, it analyzes the sub address in the signal, transmits to the terminal B15 and also makes the device 16 and the terminal A11 communicating. Then, data of the terminal A11 is sent to the device 16 in an information format A, undergone inherent data comparison, converted into an information format B and sent to the terming B15, and the terminal A11 communicates with the terminal B11 in real time.

2. Description of the Related Art In a portable terminal, since a communication modem, an OS (operating system), and a database are unique to each company, mutual communication may not be performed in some cases. In addition, portable terminals need to be reduced in size and weight and simplified in information processing in order to carry them. If direct communication cannot be performed between the mobile terminals, the mobile terminal connects to the mobile terminal data conversion device for communication, temporarily stores information in the mobile terminal data conversion device,
After disconnecting the communication connection between the portable terminal and the portable terminal data converter, the portable terminal data converter may convert the information, and transmit the converted information from the portable terminal data converter to the other portable terminal.

However, in this case, there is a problem that real-time processing cannot be performed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable terminal information conversion communication control method which enables real-time communication between portable terminals having at least one of a data format and a communication system different from each other. .

[0005]

According to the present invention, when data communication is attempted between the portable terminal A and the portable terminal B, inconsistency occurs in one or both of the data format and the communication format, and information cannot be exchanged. In this case, the mobile terminal A stores the destination address of the mobile terminal B in the sub-address and sends it to the mobile terminal data conversion device having both unique data format and communication method, and the mobile terminal A and the mobile terminal data conversion device The mobile terminal data conversion device detects the destination address of the mobile terminal B stored in the subaddress of the received transmission signal, and converts the mobile terminal B and the mobile terminal data conversion address as the mobile terminal B destination address. The mobile terminal data converter converts the information by comparing the unique data and the mobile terminal data conversion device. Real-time communication to.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a system configuration according to the present invention. The mobile terminal A11 makes a communication connection to the mobile terminal B15 to perform data transmission and reception. Therefore, the mobile terminal A11 transmits a signal to the wireless base station 12, and the wireless base station 1 receives the transmission.
In 2, the call is transmitted to the portable terminal B15 via the exchange 13 and the wireless base station 14.

[0007] As shown in FIG.
0, and as described above, when the communication connection 21 is established between the mobile terminal A11 and the mobile terminal B15, the mobile terminal A11 negotiates a communication protocol and a data format with the mobile terminal B15. Both terminals 1
If at least one of the communication protocol and the data format is inconsistent between 1 and 15, a disconnection 23 is sent from the portable terminal A11 to the portable terminal B15.

Then, in this embodiment, the portable terminal A11 is
Mobile terminal data converter 16 connected to exchange 13
In order to establish communication connection with (FIG. 1) and perform data transmission / reception, the mobile terminal A11 transmits a protocol identifier 30, a calling address 31, and a sub-address (a destination address of the mobile terminal B) 32 as shown in FIG. Signal 2 composed of destination address 33 and call setting type (transmission, disconnection, etc.) 34
Send 4. The radio base station 12 that has received the transmission 24 transmits the transmission to the portable terminal data conversion device 16 via the exchange 13.

The portable terminal data converter 16 which has received the transmission 24 analyzes the sub-address 32 in the signal 24, and uses the contents of the sub-address 32 as a destination number for the portable terminal B1.
Send a call 25 to 5. After the communication between the mobile terminal A11 and the mobile terminal data conversion device 16 is established (information format A), the communication (information format B) 27 is performed between the mobile terminal B15 and the mobile terminal data conversion device 16.

Accordingly, the data of the portable terminal A11 is sent to the portable terminal data converter 16 in the information format A, and the data is converted to the information format B by the portable terminal data converter 16, sent to the portable terminal B15, Terminals A11 and B15
The communication is performed in real time with the server. The transmission and reception of data between the mobile terminal A11 and the mobile terminal B15 is data communication for issuing a retransmission request when the received data has an error, and bidirectional communication is performed. In this example, communication between the exchange 13 and the portable terminal data converter 16 is assumed to be performed by ISDN, and the portable terminals A11 and B15
HS communication is assumed, and a sub-address 32 is included in a part of the transmission format.
The mobile terminal B15 via the mobile terminal data conversion device 16
This is the case where a call is received.

[0011]

As described above, according to the present invention, when direct communication cannot be performed between portable terminals, the portable terminal is connected to the portable terminal data conversion device for communication, and information is temporarily stored in the portable terminal data conversion device. However, after disconnecting the communication connection between the portable terminal and the portable terminal data converter, the portable terminal data converter converts the information and transmits the converted information from the portable terminal data converter to the other portable terminal. In order to solve the problem, the mobile terminal A stores the destination address of the mobile terminal B in the sub-address and transmits the data to the mobile terminal data conversion device having the unique data format and communication method of both the mobile terminal A and the mobile terminal A. The portable terminal data converter detects the destination address of the portable terminal B stored in the subaddress of the received transmission signal. The mobile terminal B and the mobile terminal data conversion device are communicatively connected as the destination address of the mobile terminal B, and the mobile terminal data conversion device performs information conversion by comparing the unique data, and performs mobile communication of different data formats and communication methods. Real-time communication can be performed between terminals.
