Alternatively, there is a method of receiving a call service by accessing a specific website providing an Internet phone service using a PC that can access the Internet.

An improved Internet phone service than the above-described case is a service using an existing general telephone. However, even in the case of an Internet phone service using an existing phone as it is, it has a separate Internet phone gateway access number and subscriber identification number, and first accesses the Internet phone gateway by pressing the Internet phone gateway identification number, and then again the subscriber identification number. Complex procedures such as typing them are required. Therefore, this case also has a disadvantage in that it is inconvenient for general users to use.

In addition, when an Internet phone service subscriber makes a call to a general phone or a mobile terminal, the call can be made using a conventional voice over internet protocol (VoIP) technology. There is a problem that cannot be done.

In view of the above problems, it is an object of the present invention to simultaneously transmit a call to a mobile communication terminal and a terminal.

In order to achieve the above object, according to the first aspect of the present invention, there is provided a mobile telephone service providing system including a first and a second database, an exchange, and a gateway. The first database stores and manages information including subscriber information and location information for the registered mobile telephone terminal, and the second database stores whether the receiver has logged in through the terminal, the mobile terminal information of the receiver, and when logged in. Stores and manages information, including information about the terminal. If there is a call connection request from the originator to the receiver, the exchange forwards the call to the receiver's terminal when the receiver logs in with reference to the first and second databases and the receiver logs off. If it is delivered to the mobile phone terminal. The gateway is connected to the exchange, and converts the signal from the exchange to a terminal by converting a signal in a format compatible with the network to which the terminal is connected, and converts the signal from the terminal to a signal in a format compatible with the exchange to a exchange. .

The exchange may further forward the call to the mobile terminal when the recipient is logged in.

At this time, the gateway checks the information of the terminal to which the receiver is logged in from the receiver's mobile telephone information set in the call from the caller with reference to the second database, and delivers the call to the terminal.

In addition, the information of the terminal preferably includes the IP address of the terminal, and the mobile telephone terminal information preferably includes the telephone number of the mobile telephone terminal.

In addition, the exchange preferably further includes a third database that stores the temporary location when the recipient is out of the registered area and keeps the data related to the first database the same as the first database.

According to a second aspect of the present invention there is provided a method for connecting a call to a receiver subscribed to a system for providing mobile telephone service. According to this method, first, when there is a call connection request from the originator to the receiver, it is determined whether the receiver is logged in to the system through a terminal connected to the network. If the receiver is logged in to the system, the caller then consults the terminal's information to convert the call to a compatible format on the network. The call is then forwarded to the terminal on the network in a compatible format. The next time a response is received from the called party, the call is connected.

At this time, the unconverted call can be further delivered to the receiver's mobile telephone terminal.

The system also includes a database that stores the phone number of the recipient's mobile phone terminal and the IP address of the terminal, and preferably converts the call by identifying the IP address of the terminal corresponding to the recipient's phone number in the call connection request. .

In addition, receiving a signal from a terminal allows the signal to be converted into a format compatible with the system.

The MSC 10 provides an interworking function between a mobile communication network and a fixed network such as a PSTN, an ISDN, or an interworking function between the mobile communication network and a third party vendor network. The MSC 10 exchanges information with the HLR 20, the VLR 30, and the TLR 40, which store subscriber information, and transmits and receives signals and voice data with the mobile phone terminal 80 to perform the exchange function. Match with the BSC to do this. In addition, the terminal 90 interworks with the VoIP gateway 70 to transmit and receive signals and voice data.

The HLR 20 is a database management system that stores and manages subscriber parameters, location information, and the like for all mobile phone terminals 80 registered in its area. The HLR 20 manages important data such as access capability, basic service, and additional service of the mobile phone terminal 80 and performs a routing function of the receiver.

The VLR 30 is included in the MSC 10 of the region, and temporarily stores and manages information on all the mobile phones 80 existing in the area managed by the VLR 30, and the data related to the HLR 20. Always remains the same as the HLR 20. The VLR 30 performs a function of transmitting information related to the subscriber to the MSC 10 in response to a request of the MSC 10 when the mobile communication subscriber establishes a call.

The TLR 40 stores and manages whether the subscriber is logged in, the subscriber's telephone number, the terminal ID to which the subscriber is logged in, and the IP address of the terminal to which the subscriber is logged in. The TLR 40 supports the request of the MSC 10 when the caller establishes a call. Accordingly, the MSC 10 performs a function of transmitting information related to the subscriber.

The BTS 50 is a system for wirelessly communicating with a mobile phone terminal 80 in a cell to provide a mobile communication service to a subscriber. To this end, the BTS 50 transmits and receives a radio signal to and from the mobile phone terminal 80 by encoding and decoding a radio channel.

The VoIP gateway 70 converts the data of the packet-switched format transmitted from the terminal 90 through the network into the data of the circuit-switched format and transmits the data to the MSC 10 or In addition, the process of converting the data of the circuit-switched system from the MSC 10 into packet-switched data and transmitting the data to the terminal.

The terminal 90 includes all terminals capable of logging in via a network such as a PC or a notebook.                     

Hereinafter, a mobile phone service method according to a first embodiment of the present invention will be described with reference to FIG.

2 is a flowchart illustrating a mobile phone service method according to a first embodiment of the present invention.

First, a subscriber subscribed to the mobile phone service system 100 according to the present invention installs an application program for logging in to the system 100. Such applications may be downloaded from websites, ftp sites, etc. of the system 100 or received via other transmission media. In order to log in to the system 100 through these applications, an ID and password are required. This ID uses the subscriber's telephone number, and the password can be transmitted from the system 100 through the text service of the mobile telephone terminal 80. Or the subscriber can specify the ID and password directly through the website or application. Alternatively, you can use the ID and password used in the existing service.

In this way, after the subscriber is given an ID and password and installs an application program, when the subscriber logs in to the mobile telephone system 100 through the terminal 90 (S201), the subscriber logs in the information and the ID of the terminal 90 or The IP address of the terminal and the like are stored in the TLR 40 of the system 100 together with the telephone number of the mobile telephone terminal 80 (S202). When the caller attempts to connect to the subscriber when the subscriber is logged in as described above, the MSC 10 refers to the TLR 40 to determine whether the subscriber is logged in to the system 100 (S203).                     

If the subscriber is logged off to the system 100, the location of the subscriber is checked with reference to the HLR 20 or the VLR 30 (S211). That is, first, it is determined whether the subscriber is presently located in the home, which is the location of the subscriber when the subscriber joins, and when the subscriber is located outside the home, the location of the subscriber is determined by referring to the VLR 30. After confirming the subscriber's location, the call is transferred to the subscriber's mobile terminal 80 (S212). When the subscriber answers the mobile telephone terminal 80, the call channel is established (S213).

When the subscriber is logged in to the system 100, the TLR 40 checks the ID of the terminal 90 or the IP address of the terminal 90 (S221), and transmits the call to the terminal 90. .

In this case, when the MSC 10 transmits a call to the terminal 90 where the subscriber is logged in, the call is first transmitted to the VoIP gateway 70 (S222). The VoIP gateway 70 checks the IP address of the terminal 90 to which the subscriber is logged in corresponding to the telephone number specified by the caller when the call is set up by referring to the TLR 40, and replaces the portion corresponding to the telephone number with the IP address. The call is transferred to the terminal 90 by converting to S223.

The application installed at terminal 90 then asks the subscriber to answer the call from the caller. Then, for example, the subscriber's mobile telephone terminal 80 indicates that the bell rings briefly and that the incoming call is received to the terminal 90 on the liquid crystal. When the subscriber answers to the terminal 90, a call channel is established between the caller and the subscriber (S224).

As such, after a call is established between the caller and the subscriber, voice call data between the caller and the subscriber can be exchanged with each other.

In order for the MSC 10 to exchange voice call data with the terminal 90, the MSC 10 first receives the voice data from the caller and forwards it to the VoIP gateway 70. The VoIP gateway 70 converts the voice data into a digital signal in a format usable on the Internet and delivers it to the terminal 90 through the Internet. On the contrary, when the VoIP gateway 70 receives a digital signal from the terminal 90, the VoIP gateway 70 converts the digital signal into an analog signal usable by the MSC 10 and transmits the analog signal to the MSC 10.

Thus, in the first embodiment of the present invention, if the subscriber is logging in to the system 100 through the terminal 90, the call is transferred only to the terminal 90, but the call is simultaneously transferred to the mobile telephone terminal 80 and the terminal 90. You can also pass it.

At this time, if the subscriber answers the mobile telephone terminal 80, the call is set to the mobile telephone terminal 80, and if the subscriber responds to the terminal 90, the call is set to the terminal 90, and the call channel is established between the caller and the subscriber. Is set.

When the subscriber answers the mobile phone terminal 80, the call setup request to the terminal 90 is blocked, and when the subscriber responds to the terminal 90, the call setup request to the mobile phone terminal 80 is blocked. do.

As described above, according to the present invention, when the subscriber is out of the area where the mobile phone can be called, if the subscriber is logged in to the system 100, a call setup request to the subscriber can be transmitted to the terminal. Therefore, even if the subscriber leaves the callable area, the call can be received at any time as long as the subscriber is logged in to the system 100.

When a call is connected to a subscriber who is subscribed to a mobile phone service providing system according to the present invention, a call can be simultaneously delivered to a mobile phone terminal and a terminal. Thus, the call can be delivered to the terminal even when the subscriber is out of the coverage area. In addition, the terminal and the call channel are set up, thereby reducing the charge.
