A FIXED-LINE NUMBER CALL MANAGEMENT SYSTEM AND METHOD BY A MOBILE APPLICATION
Technical Field
The present invention relates to a system and method for using calling capabilities of a fixed-line number that is defined in a mobile application over a mobile application in cases where there is no access to mobile voice network however there is access to mobile data network or wireless internet network by internet protocol multimedia subsystem network.
Background of the Invention
Today, applications that can be run on mobile devices such as smartphone, tablet computer have become diversified with the rapid development of technology. Users can carry out a wide variety of transactions that will facilitate their daily lives by means of applications on their mobile devices. The most preferred of these applications are VOIP (voice over internet protocol) applications which provide internet technologies for telephone calls whereby users can make voice and video call by internet protocol.
In the state of the art, calls incoming to a fixed-line number over a device wherein SIM card of a mobile number is inserted can be received by routing a fixed-line number to a mobile application by means of a call routing service over a network. However, it is not possible to make a call over a mobile device wherein SIM card of a fixed-line number is inserted in this method.
Therefore, considering the studies and the deficiencies in the state of the art, it is understood that there is need for a system which enables users to manage outgoing calls over a mobile device wherein their SIM card is inserted over a mobile application by their fixed-line number, and to manage calls in cases where there is no access to mobile voice network however there is access to mobile data network or wireless internet network as well.
The United States patent document no. US20130142065, an application in the state of the art, discloses a system for receiving users’ voice communication request from fixed-line or mobile network numbers incoming to their fixed-line phone number or mobile phone number upon the users are registered with their fixed-line phone number and mobile phone number over a mobile VoIP-based mobile application, and sending a voice communication request to their fixed-line or mobile network numbers over a fixed-line phone number or a mobile phone number, and providing another rich content management; and operation method of this system. The system in the said invention enables users to carry out fixed-line and mobile network communication transactions within a VoIP -based Fixed-Line Mobile Clustering application, and to manage other rich content data. In the said invention, it is enabled to route incoming or outgoing fixed-line telephone calls to a cellular phone or a smartphone by means of a network gateway for connecting PSTN and a similar fixed-line telephone network to a data connection network. Fixed-line telephone calls can be routed as a call or SMS request. Signalling and data transfer can be provided over a separate or shared server. One or multiple fixed-line telephone number connects/connect a fixed-line telephone network and a data network in a wireless or wired way; one or more mobile device can connect to the said fixed-line telephone numbers or network gateways. The system in the invention enables management of calls which are incoming from a PSTN network to a fixed-line telephone and transmitted to other telephone numbers over a fixed-line telephone number from a mobile device. A call over a PSTN or a call incoming from a fixed- line telephone network provider such as ADSL is converted into a VoIP format by means of a conversion method such as SIP, RTP over a voice gateway or network gateway and then it is transmitted to a Fixed-Line Mobile Clustering application over a data connection.
