BEST MODE FOR CARRYING OUT THE INVENTION The device of the present invention numerically indicates the communication relationship between communication terminals based on the communication information such as the number of times communication is performed, the communication time, and the amount of communication information obtained from a network device such as a switching device. Memorize. Hereinafter, the numerical value of the communication relation between the communication terminals will be referred to as a communication relation value.

The communication-related value is a function F that receives communication information such as the number of times communication is performed between communication terminals, communication time, and communication information amount.
It is calculated from (the number of communications, the communication time, the amount of communication information).

For example, in the case of calculating only from the number of times of communication, the function of the communication-related value is communication-related value = number of communication.

The device of the present invention also stores the communication direction from the source terminal to the destination terminal.

Further, in the device of the present invention, when a user specifies a specific server terminal or communication terminal as a search condition, the communication relation value with the specific server terminal or communication terminal is a constant value C.
A source terminal group that is one or more and has the specific server terminal or communication terminal as a destination terminal is extracted. This extracted source terminal group is called a high-frequency source group.

Further, regarding each server terminal or communication terminal of the high-frequency transmission source group, among the reception destination terminals having the server terminal or the communication terminal as a transmission source terminal, the reception destination terminal group having a communication-related value of C2 or more. To extract. This extracted destination terminal group will be referred to as a high-frequency destination group.

Next, based on the extracted communication relation values between the individual source terminals of the high-frequency source group and the individual destination terminals of the high-frequency destination group, the high-frequency source group and the high-frequency call reception are performed. The communication relation value with each destination terminal of the destination group is calculated. This communication relation value will be referred to as a communication relation value with the high frequency transmission source group.

The communication relation value between a certain destination terminal and the high-frequency transmission source group is, for example, the communication relation with the high-frequency transmission source group = (the communication relation between the reception destination terminal and the transmission source terminal belonging to the high-frequency transmission source group). Sum of values) /
(The number of source terminals belonging to the high-frequency source group for which the communication relationship value is set with the destination terminal) is calculated by the following formula.

The device of the present invention introduces a destination terminal group whose communication relation value with the high frequency source group is a constant value C3 or more. The group of destination terminals to be introduced will be referred to as a group of destinations for introduction.

The values of C1, C2 and C3 can be set as initial values of the apparatus or freely by the user, and the accuracy and range of introduction can be modified by the set values.

FIG. 1 shows the relationship between the specific terminal (specific destination), high-frequency source group, high-frequency destination group, and introduced destination group.

For example, when the communication-related value is determined only from the number of times of communication, a group of terminals that frequently access a specific server terminal or communication terminal designated by the user becomes a group of incoming call destinations.

That is, since the communication-related value is automatically set and stored according to the communication information such as the number of times of communication between terminals, the communication time, the communication information amount, etc., the relationship setter is not burdened.
And it is not limited to the link setting (introduction) with the known information (or server terminal) of the relation setting person. Therefore, there is no bias in the communication partners that can be introduced.

Further, since the communication-related value is automatically corrected according to the use of communication, it is possible to introduce the communication partner by reflecting the temporal change of the usage status of the user group.

The method of the present invention will now be described with reference to a simple concrete example.

For each of 1, D3, D4 and D5, the total number of times of communication with the sources belonging to the high frequency source group and the number of source terminals belonging to the high frequency source group are obtained.

(3) From the total number of times of communication and the number of source terminals, the average number of times of communication (C3) per source terminal is calculated for each destination that belongs to the high frequency destination group, and this is 10
If you ask for a destination that is more than once, it becomes D3 and D4,
These are the destinations to be introduced as communication partners.

(1) Access valuable server terminals many times. (2) Many people access valuable server terminals. (3) The reference time of a valuable server terminal becomes long. (4) When a large amount of information is downloaded from the server terminal, it has valuable information.

According to the present invention, the value of the server terminal is held as the communication-related value, and the specific server terminal is designated as the search condition for the valuable server terminal.
Introduce a group of server terminals that are expected to have the same kind of value that are closely related to communication. Thus, the user of the present invention can walk through valuable server terminals by sequentially selecting arbitrary server terminals from the introduced server terminal group, and cannot find unexpectedly by the conventional search. The server terminal can be found.

Further, in the conventional communication partner introducing device such as the World Wide Web, since the relational setting is artificially made, there is a limit in the number and range of link setting, but in the present invention, as long as communication is performed, Automatically generate a large number of relationships,
In addition, it can be expected that the generation range will be expanded.
