Description

The invention relates to the field of telephone management, in particular to the call control protocol in the telephone network.

Subscribers of modern telephone networks in the absence of a credit tariff or a prepaid telephone communication time cannot continue to use the telephone network, in particular, to call someone over the telephone.

Currently, there are well-known call control protocols, thanks to which callers who do not have enough money to pay for the current call can bring to the attention of the called subscriber information about the call attempt he has made.

The prior art knows a method of controlling telephone communication, which consists in tracking or controlling call attempts made by calling users in the network with the determination of call attempts by calling users having credit or airtime insufficiently to call the called user (to the intended addressee), and they transmit to the called user a request to make a call (connection request), notifying the called user via his telephone about Attempts to call it, without necessarily establishing a conventional compound. This solution “Call Management Protocol with Insufficient Credit” was chosen as a prototype (patent RU 2341908, IPC Н04М 17/00, priority. 05/07/2004, PCT Publication: WO 2004/100521 (11/18/2004).

A disadvantage of the known solution is the low reliability of establishing information telephone connections in the conditions of insufficient funds in his account of a positive balance, and to the calling subscriber about the state of his account. In such cases, the need to pay for the connection falls on the shoulders of the called subscriber, who now acts as the calling party. However, not always this decision leads to the fact that the called subscriber makes a call at his own expense.

Often, the inability to make a connection is due to the fact that the phone of the called party is turned off, is outside the access zone, which in itself is the cause, unrelated to the lack of funds in the caller’s account, and does not allow you to make a connection.

The technical problem that should be solved by the present invention is to create a reliable and user-friendly way of informing the caller about the possibility to make a call to the called subscriber and at the same time inform the caller about the state of his account, thereby creating sufficient informational conditions for the caller to make the connection he needs.

The technical result is to improve the reliability and convenience of telephone communication in the case of using it by a person who does not have sufficient funds in the account to make outgoing calls and its awareness.

The attached figures present the proposed scheme for implementing the method for subscribers of the same network of one telecom operator (Fig. 1) and for subscribers of the networks of different telecom operators (Fig. 2).

The stated technical result is achieved as follows.

The method of managing connections in a mobile network includes the following steps:

- provide access to the above-mentioned mobile communication network to a calling subscriber who does not have sufficient funds in the account;

- receive from the caller initiated by him a call to the called subscriber;

- send a message (sms or voice message) to the calling subscriber about the impossibility of establishing a connection with the called subscriber due to the lack of sufficient funds on the account for making outgoing calls;

- interrupt initiated by the caller a call due to disconnection, independently performed by the caller;

- after disconnection, send a message to the calling subscriber about the availability of the called subscriber.

Advantageously, after the aforementioned interruption of the call from the caller, an inadequate funds for the call is generated for the said caller.

In the claimed method, the network of the same operator or a network of different operators is used as the mentioned mobile network.

The implementation of the claimed method is illustrated in figures 1 and 2.

Example I. An example of the method with the network of one operator (Fig. 1).

The passage of the call according to the implementation of the claimed method is carried out sequentially as follows:

1) Platform 1 initiates a call (signal I-1) to the called number using an IAM message using the ISUP protocol, which reaches the business switch 2-1 of the network in which the called subscriber is registered.

2) The visiting switch 2-1 after the interruption of communication by the subscriber, initiates the occupation of the radio channel by means of the base station controller 3-1 and the base station 4-1, and sending a SETUP signal message (signal I-2) on the Um interface to the mobile device of the called subscriber 5; At the same time, the calling subscriber terminates the connection after receiving the message (sms or voice message) about the impossibility of establishing a connection with the called subscriber due to the lack of sufficient funds in the account for making outgoing calls.

3) The mobile device of the called subscriber initiates procedures for notifying the subscriber of an incoming call (signal I-3).

4) The mobile unit of the called subscriber confirms the activation of the incoming call indication with the CALL CONFIRMED signal (I-4 signal).

5) Operator's network switch 2-1 transmits the ALERTING signal message to the ISUP CPG signal message and sends it to platform 1 (I-5 signal).

6) The platform 1, having received an indication of the delivery of the call to the called subscriber's office, sends an SMS message (signal I-6) to the calling subscriber 6 about the availability of the called subscriber.

7) Having received an indication of the delivery of the call to the called subscriber’s office, platform 1, stops the connection to be established with a signal message REL (signal I-7).

8) The visiting switch 2-1 transmits the final message to the RELEASE message towards the mobile device of the called subscriber 5 (I-8 signal), after which the corresponding resources are released, including on the radio subsystem.

9) When the Release message (I-9 signal) arrives at the mobile device, the incoming call notification procedure is terminated.

10) On the mobile phone of the called subscriber, a notification on the availability of the calling subscriber is displayed on the screen and in the incoming call log (I-10 signal).

This scenario, due to the universality of the principles of establishing telephone connections and the mutual compatibility of telephone signaling protocols, works for other telephone networks (LTE, IMS) of all generations (2G, 3G, 4G, 5G).

Example II An example of the method implementation using a network of different operators is explained in FIG. 2, where the following positions are indicated:

1 - platform;

2-2 - the visiting switch of the network in which the called subscriber is registered;

3-2 - base station controller;

4-2 - base station;

5 - the mobile device of the called subscriber;

6 - the caller;

7 - transit switch of the first network;

8 - transit switch of the second network.

The passage of the call in accordance with the considered example is as follows:

1) Platform 1 initiates a call to the called number using the IAM message via the ISUP protocol (signal II-1), which reaches the transit switch of the first network 7.

2) The transit switch 7 determines the belonging of the number of the called operator and sends a call (signal II-2) to the junction with the operator where the routing for the given number of the called subscriber is defined.

3) The call enters the network of the operator of the called subscriber, and the transit switch, having determined the location of the subscriber on the internal network of the operator, sends the call (signal II-2) to the visiting switch 2-2.

4) The visiting switch 2-2, after the call has been broken by the caller, initiates the occupation of the radio channel by the base station controller 3-2 and the base station 4-2, and sends a SETUP signal message (signal II-3) via the Um interface to the mobile device of the called subscriber 5; at the same time, the caller independently disconnects after receiving a message (sms or voice message) about the impossibility of establishing a connection with the called subscriber due to the lack of sufficient funds in the account for making outgoing calls.

5) The mobile device of the called subscriber initiates the procedures for notifying the subscriber (signal II-4) of an incoming call.

6) The mobile unit of the called subscriber confirms the activation of the incoming call indication with the CALL CONFIRMED signal (signal II-5).

7) The visiting switch 2-2 transmits the ALERTING signal message to the ISUP CPG signal message and transmits (signal II-6) through the transit switch of the second network 8.

8) The message (signal II-7) is transmitted from the transit switch of the second network 8 to the transit switch of the first network 7 and from it platform 1 (signal II-8).

9) Platform 1, receiving an indication of the delivery of the call to the called subscriber’s office, sends an SMS to the calling subscriber about the availability of the called subscriber (signal II-9) and stops establishing the connection with a signal message REL (signal II-10), which is transmitted to the second transit switch networks (signal II-11) and, further (signal II-12), to the business switch 2-2.

10) Switch 2-2 translates the final message in the RELEASE message (signal II-13) towards the mobile device of the called subscriber 21, after which the corresponding resources are released, including on the radio subsystem.

11) When the Release message (signal II-14) arrives at the mobile device, the procedure for notification of an incoming call is terminated.

12) On the mobile phone of the called subscriber, a missed call notification is displayed on the screen and in the incoming call log (signal II-15).

The proposed method provides a convenient and fast connection of these services, in which the subscriber does not need to remember and enter USSD commands, call service activation numbers, create, address and send SMS messages from his phone or enter a special code before the phone number of the called user to send a message to the called user, etc. The provision of services is offered to him directly at the time of the call attempt.

The described method has several advantages, in particular, it allows, by informing the caller about the possibility of calling the called subscriber to provide the necessary connection. In addition, the caller, breaking the connection independently, thereby avoiding accidental connections, for example, due to technical failure, with the called subscriber, which would be subject to payment.
