FIELD: information technology.
SUBSTANCE: number of the dialed characters of the phone number of the called subscriber is counted in the telephone when every next character of the dialed telephone number is entered, the entered number is normalized when the number of dialed characters reaches the number 3 and the outbound request is formed by the telephone to determine the calling tariff of the dialed telephone number. The generated request is transmitted to the request processing server intended for processing requests from the subscriber terminals, the dialed number is allocated from the request received by the request processing server, and the tariff value corresponding to the country code in the dialed telephone number is determined. Then, a response is formed to the telephone containing the detemined tariff value, the generated response is sent to the phone and the tariff value is displayed from the received response on the phone display. Alternatively, after normalizing the entered number, the call tariff value corresponding to the country code in the dialed telephone number is found in the phone in which call tariff values are updated from the server upon request or proactively.
EFFECT: expanded arsenal of technical means of predictive tariffication, reduced load on telephone networks.
