In this case, the intimacy calculator 522 may assign the same weight to each item included in the relationship information, or may assign a different weight to each item.

For example, in the case of teenagers, SMS and MMS usage history is more frequent than those in their thirties. On the contrary, in the case of thirties subscribers, if the call history is larger than that of teenagers, the same weight is applied to each item. This is because assigning different weights according to the age groups of the subscribers than calculating the more accurate intimacy can be calculated. In addition, when the subscriber's job is a sales job, a higher weight can be given to the call history than the research job, and when the subscriber is a woman, a higher weight can be given to the SMS and MMS use history than the man.

3 and 4 are schematic diagrams showing an example of weights assigned to respective items included in the relationship information on the basis of age and gender, respectively.

As shown in FIG. 3, it can be seen that the teenagers have higher weights for the SMS and MMS usage histories than the twenties and thirties, but have lower weights for the call history, and in the twenties, the weights for the portal service usage histories. Is high, and in the thirties, the weight for the call history is high. In addition, in FIG. 4, the weight of the call history is higher than that of the woman, but the weight of the SMS usage history is low, and the weight of the portal service history is the same.

At this time, the above-described values for the weights shown in FIGS. 3 and 4 are merely examples to show that the weights are high and low, and the weight value may be changed according to the policy of the network operator.

Accordingly, the intimacy calculator 522 may weight each item included in the relationship information for each subscriber according to the weights shown in FIGS. 3 and 4 and calculate a weighted result. In addition, the calculated intimacy can be arranged in order from the larger the resulting value.

In addition, the embodiment of the present invention has been described in the case of giving different weights according to the age group or gender of the subscriber as shown in Figures 3 and 4 described above, for example to help understanding of the present invention However, the present invention is not limited thereto. If the subscriber moves frequently, the geographical information may be given a high weight. If the call with a specific acquaintance is frequent, the plan information may be given a high weight, but the present invention is not limited thereto.
