JO3203B1 - Method For Notification Of A Called Subscriber In The Absence Of Sufficient Credit Of The Calling Party - Google Patents

Abstract

The invention relates to telephone communication, in particular to methods for notification of the called subscriber in the communication networks, namely in the absence of the calling party's valid credit account, and can be used in existing mobile telecommunications systems, including GSM, 3 GSM, 3G, CDMA, WCDMA, and others. In the method each 10 subscriber of the network is provided with an opportunity to get network access for outgoing calls, regardless of the status of his/her account, and to accept the call and/or receive the calling subscriber's messages without the pre-paid credit account. The calling subscriber dials the phone number of the called subscriber; the operator of the calling subscriber determines his solvency; upon initiation of a call by the calling subscriber, who 15 does not have a valid credit account, for its transmission to the called subscriber the outgoing call is directed through the operator serving the calling subscriber to a forwarding and controlling server and at its command disconnects the calling subscriber. The forwarding and controlling server processes the obtained information and forms a transit call, by the transit call through the operator serving the calling subscriber is 20 transferred an outgoing call to the operator's network serving the called subscriber as an information call, notifying of the missed call. A notification about the missed call is created for the called subscriber, providing information about the calling subscriber, and the information call is disconnected after its receipt by the called subscriber. The result, obtained by means of the claimed method, consists in increasing the reliability and ease of 25 communication between subscribers in an irregular situation, namely upon insolvency of the calling subscriber.
