Description

Field of technology

The present invention relates to a system that allows users to make calls using a second mobile phone number using a mobile device, and that uses the first number without the need for a second device using a mobile application in an IP multimedia subsystem (IMS).

Prerequisites for creating the invention

Telecom operators provide mobile network services to their subscribers using multiple numbers. Therefore, subscribers answer incoming calls and text messages (SMS) on two different mobile devices, or make calls or send SMS using two different mobile devices. Today, calls received to the second number on a device in which the SIM card of the first device is installed can be answered by transferring a call from the second number to the first using the call transfer service over the GSM mobile network. However, this method does not allow calls from the first number through the device into which the SIM card of that number is inserted, using the second number. Therefore, there is a need for a solution that allows users to manage calls to second numbers through one mobile device, and to make and manage outgoing calls from a mobile device that has a SIM card of another number using second numbers.

US Patent Document No. US2015201086 describes a virtual phone application system for making, receiving calls and sending text messages from another number on the same phone. This invention provides for the use of a device connected to the Internet, i.e. capable of connecting to other devices over the Internet, such as a telephone or other device configured to use a virtual phone application. In it, a telephone number is assigned depending on a certain standard, and the application itself provides regular telephony and communication services (receiving, answering calls and sending SMS) using the VOIP protocol. A communication system based on this invention

consists of: a virtual phone application installed on the device, whose configuration allows you to make calls, a VoIP server configured to receive and analyze the number dialed on the device, and a Session Border Controller (SBC) configured to receive calls from the VoIP server. The virtual phone app is also capable of receiving incoming calls from any phone line. In another embodiment, the invention also provides a communication system for sending text messages using a virtual phone application over a VoIP network between an Internet-enabled telephone device and a device connected to any other telephone line. This system consists of: a virtual phone application configured to accept an SMS request, a web server configured to receive SMS over the secure hypertext transport protocol (HTTP), a vector signal generator (VSG) configured to receive text messages over the control protocol data transfer (TCP) from a web server, an SMS gateway configured to receive text messages via HTTP, an SMS center (SMSC) configured to receive text messages sent to the recipient. The virtual phone app is also capable of receiving text messages sent from any phone network.

International Patent Document No. WO2018154570 describes a system for creating a second virtual space on a single SIM mobile device, as well as a main workspace. This system allows you to create a second phone work environment to eliminate the need to use two physical phones. In this invention, one smartphone module is assigned a second phone number, and a second workspace is associated with new user accounts, such as email and social networking applications. Additionally, the second phone number added is associated with text messaging accounts such as SMS and WhatsApp. The system uses client software, a database server, a Direct Internal Dialing (DID) provider, an application server, and a storage server. The server side contains sets of tables with information and data about the end users' transactions, such as the user's phone number, email address, name, location of the user's files in storage, user settings. The application server is responsible for: calling, receiving calls, managing calls and quality of service. A mobile smartphone application is downloaded onto the device to add a second or more virtual spaces to the physical environment of the smartphone, and the user registers it with the application

by creating a user profile. The second phone space created with this application is associated with a new phone number. The user who gets a new phone number and creates a virtual space after downloading and registering the application can perform all operations in the real operating system.

The invented system (1) for making and receiving calls to the second number consists of:

- at least one mobile device (2) served by a mobile network via a SIM card (subscriber identity module) of a mobile network operator, which is configured to run at least one application on it;

-at least one mobile application (3) that can be run on a mobile device (2) that supports Voice over Internet Protocol (VoIP) and the SIP (Session Establishment Protocol) and SRTP (Secure Real Time Protocol) signaling protocols for voice transmission;

- at least one registration node (4), ensuring registration of the user in the mobile application (3) according to his first number, determined by his SIM card installed in his mobile device (2), as well as coordination of the second and first numbers in mobile networks subscriber systems (A); And

- at least one signal control node (5), which exchanges data with the IMS (M) mobile network, provides signal control using the second number, ensures registration of the mobile application (3) in the IMS (M) mobile network using the second number and its activation into the life cycle of the mobile application (3), receives calls transmitted to the second number from the IMS (M) mobile network and/or transfers calls made by the user through the mobile application (3) using his second number to the IMS (M) mobile network .

In a preferred embodiment of the invention, the mobile device (2) is a device such as a mobile phone, smartphone, tablet computer, which is connected to a mobile communication network using a SIM card and is adapted to run at least one mobile application (3) on it. .

In the system of the present invention (1), the mobile application (3) includes a SIP client, and the connection between it and the control node (5) is carried out using the SIP protocol. Voice transmission between the mobile application (3) and the IMS (M) mobile network is provided using the SRTP protocol. The mobile application (3) is registered by the signal control node (5) using the first SIM card number of the mobile device (2). Each time it is opened, the mobile application (3) performs authentication and registration operations (SIP registration) using the “SIP Digest Authentication” method on the first number.

The mobile application (3) creates a new account by processing the second number information included in the second number matching information that it receives from the registration node (4) after performing the authentication and registration operation (SIP registration), using the method SIP digest authentication also applies to information about the second number.

The mobile application (3) transmits a request to make a user call to the signal control node (5) using standard methods defined in the SIP signaling protocol over the Internet Protocol using the second user number. The mobile application (3) ensures that the signal control node (5) transmits the call to the IMS (M) mobile network. Voice transmission is started by the IMS (M) mobile network after the mobile application (3) receives a request for an incoming call. The mobile application (3) transmits voice packets directly to the media server specified to it by the IMS (M) mobile network by sending signals when processing a call. The IMS (M) mobile network provides two-way voice communication between the mobile application (3) and the called number.

The mobile application (3), in which the second number is registered, receives a request to make a call from the signal control node (5), which is connected to the IMS (M) mobile network in the form of a push notification (PN) through services supported by the mobile device operating system (2) when a call comes to the second number. The user receives a call through the mobile application (3), and the signal flow between the signal control node (5) and the IMS mobile network (M) is terminated. When sending a call request from a number to a second number registered in the mobile application (3), the call request is first transmitted to the IMS (M) mobile network. The IMS mobile network (M) transmits the call request to the signal control node (5) to transfer the received call request to the client registered in it. The signal control node (5) sends a request for an incoming call in the form of a push notification (PN) through services supported by the operating system of the mobile device (2), for its further transmission to the mobile application (3), in which the second number is registered.

In a preferred embodiment of the invention, the registration node (4) is a node in which a subscriber of the mobile communication network receives a request to use the second number through such communication channels as a website, SMS transmission channel, telephone directory service provided by the operator, after which the operation is performed registration. The registration node (4) receives information about the first and second user number through special services defined by REST (Representation State Transfer) interfaces over HTTPS (Hypertext Transport Protocol Secure) from mobile network subscriber systems (A). The registration node (4) registers the correspondence of the first number and the second number with reference to

second number identification request, which it receives from the mobile network subscriber system (A) in its database and transmits information, including information about the second number, that the second number identification has been completed, to the mobile application (3) via push- notifications (PN). The push notification sent by the registration node (4) is sent through the interface supported by the operating system of the mobile device (2), which is running in the mobile application.

In the system of the present invention (1), the signal control node (5) is a node in which the mobile application (3) is registered in the IMS (M) mobile network using a second number, and the registration of the mobile application (3) is stored in throughout its entire life cycle. The signal control node (5) allows you to maintain the registration of the second number in the IMS (M) mobile network by updating the registry. The signaling control unit (5) sets the IMS(M) mobile network registration status of the second number through a subscription operation. Information about changes in the registration status of the number in the IMS mobile network (M) is transmitted to the nodes subscribed to receive the registration status, and the signal control node (5) receiving such information updates the registration operation and notifies that the registration operation is completed.

The system that is the subject of the present invention (1) allows call management, and the user can make and receive calls using VoIP technology through a mobile application (3) in cases where there is no access to a mobile voice network, but there is access to a Wi-Fi network . In addition, the user is charged by the operator of the second number without additional operations in cases where the user makes a call using his second number in the system (1).

Based on these basic principles, it is possible to develop various versions of the system that is the subject of the present invention for making and receiving calls to a second number (1); the invention is not limited to the examples given in this document, and in its essence corresponds to the claims.
