And a communication terminal ID 32 which is identification data of the communication terminal 3b registered by the telephone number system on the communication network 2b side;
A communication protocol 33 for controlling communication connection between the communication terminal 3a and the communication terminal 3b and a communication speed 34 for determining a communication speed at the time of communication connection between the communication terminal 3a and the communication terminal 3b are registered. .

Specifically, if the communication terminal ID 31 is "45"
6 "and the communication terminal 3b having the communication terminal ID 32 of" 999 ", the communication protocol 33 is" V.22b ".
"is", the communication speed is "2400 bps" for connection communication. The communication terminal 3a having the communication terminal ID 31 of "123" and the communication terminal 3b having the communication terminal ID 32 of "321" are connected and communicated at the communication protocol 33 of "V.32" and the communication speed 34 of "1200 bps". The communication terminal 3a whose communication terminal ID 31 is “789” and the communication terminal ID 3

The database registration device 4 sorts (sorts) the database of the database storage unit 21 based on a certain standard and registers it in the data storage unit 11a. There is provided a data sorting unit 22b to be registered in the data storage unit 11b.

The data sort means 22a sorts the database of the database storage means in descending order based on the communication terminal ID 31 and registers it in the data storage means 11a. The data sort means 22b compares the database of the database storage means 21 with the communication terminal ID 32 as a reference. And is registered in the data storage means 11b. FIG. 4 is an explanatory diagram showing the contents of the database after sorting, and FIG.
31 shows the registered contents of the data storage means 11a sorted in descending order, and (b) shows the registered contents of the data storage means 11b sorted in the communication terminal ID 32 in descending order.

In this configuration, when there is a connection request from the communication terminal 3a accommodated in the communication network 2a, the data detection means 12a detects the identification data of the communication terminal 3a. Then, the detected identification data is stored in the data storage unit 11.
a to determine whether the data is registered in the data search
Search for and judge.

Communication terminal ID 31 of data storage means 11a
If the identification data detected by the data detection means 12a is present, the data search determination means 13a performs connection communication between the communication terminal 3a and the communication terminal 3b based on the communication terminal ID 32, communication protocol 33, and communication speed 34 corresponding to the identification data. I will provide a.

When there is a connection request from the communication terminal 3b accommodated in the communication network 2b, the data detecting means 12b detects the identification data of the communication terminal 3b. Then, the data search determining unit 13b searches for and determines whether the detected identification data is registered in the data storage unit 11b.

Communication terminal ID 32 of data storage means 11b
If the identification data detected by the data detection means 12b is present, the data search determination means 13b uses the communication terminal ID 31, communication protocol 33, and communication speed 34 corresponding to the identification data to connect the communication terminal 3a to the communication terminal 3b. I will provide a.

As described above, the data storage means 11a has:
Communication terminal I of communication terminal 3a accommodated in communication network 2a
Since it is sorted in descending order using D31 as a key,
The data search judging means 13a can instantaneously search by a high-speed search method such as a binary search method. This is the same in the data search determination means 13b.

If a search is made by directly searching the database information registered in the database storage means 21, the search processing time becomes enormous. Therefore,
It is conceivable to increase the speed of the search process by registering the information with a certain regularity based on certain identification information.

However, when the information to be identified is different depending on the communication network requested to be connected as in this communication system, for example, the communication terminal ID 31 which is the identification data of the communication terminal 3a accommodated in the communication network 2a is used as a reference. Is registered with a certain regularity, it is necessary to search based on the communication terminal ID 32 at the time of a connection request from the communication terminal 3b accommodated in the communication network 2b. Therefore, the search processing time at that time becomes enormous.

Therefore, the data storage means 11a, 11b is provided for each of the communication networks 2a, 2b, and the data is stored according to a standard suitable for each communication network, so that the search process can be speeded up. .

In the above-described embodiment, the identification information serving as the reference for the search is stored in the communication terminal ID 31 and the communication terminal ID 32
However, the present invention is not limited to these two types. Further, in the above-described embodiment, communication between heterogeneous networks has been described. However, it is needless to say that the present invention can be applied to communication between similar networks.

[0028]

According to the present invention, even when a single piece of database information is used, when a plurality of pieces of identification data are required for communication between networks, a certain regularity is set in advance based on each piece of identification data. By storing the data in a plurality of formats, it is possible to speed up the search of the identification data, and to quickly connect the communication between the terminals between the networks.
