The present invention relates to a wired / wireless integrated call service system using a wired telephone and a portable internet / wireless LAN, and a method thereof, and a computer-readable recording medium recording a program for realizing the method. Wired / wireless integrated call service system and method, which can provide wired / wireless voice call service to a single landline telephone number using a portable internet or wireless LAN, and can be read by a computer recording a program for realizing the method. It relates to a recording medium.

Currently, there are two methods of providing a call forwarding service for a general call: a switch-based call forwarding service (call forwarding service), and a 'pass call service' using an intelligent network system.

The switch-based call transfer service (call forwarding service) is a method of registering an automatic routing using a telephone when a subscriber goes out, and the 'pass call service' is received for a predetermined time when a telephone call is made from a landline telephone. An intelligent network service that automatically routes to mobile phones.

However, the 'switch-based call forwarding service (routing service)' for routing missed calls is a cumbersome problem because the subscriber must press the code directly on the telephone to select the call forwarding / release when the subscriber is out and back. have.

In addition, in the case of the 'pass call service' using the intelligent network system, the caller must wait for a long time (no answer waiting time) because the call forwarding is routed only after waiting for an unanswered waiting time, and thus the completion rate of the call connection is inevitably reduced. .

However, services currently provided for communication on the Internet include a messenger and a VoIP service. However, since both the messenger service and the VoIP service are provided through the Internet, it is difficult to use the service unless the user is seated. That is, it is impossible to use both services while the user is away.

In particular, the current VoIP service provides a service for calling / receiving through a 070 Internet telephone number (hereinafter referred to as a 'first service'), but the first service is a landline telephone number and a landline telephone number. Another form of Internet phone number (070 phone number) must be maintained at the same time, there is a problem that the cost increases according to the number. In the case of overseas business travelers, in particular, it is possible to make an outgoing call using an Internet phone (internet phone) or an international call, and can receive a call through mobile phone roaming.

In addition, although the messenger service provides a service for transmitting messengers with messenger IDs (hereinafter, referred to as 'second service'), the second service is not linked with a landline telephone and can be made through a mobile communication network. Incoming calls to a messenger have an impossible problem.

Currently, most users who use voice call service are using mobile communication service and wired telephone service at the same time, and user identification number has both landline telephone number and mobile communication number.

Accordingly, a user using a voice call service has a cost problem of maintaining both a wired and a wireless communication service at the same time and a confusion in having a wired telephone number and a wireless telephone number at the same time. In addition, the cost problem is expected to increase further if the user wants to receive the service up to the mobile Internet service (WiBro service). For reference, the portable Internet service refers to a service that can receive Internet service, that is, a data service outdoors while on the move (Internet access of about 1-3Mbps during the move (about 60 km / h)).

In addition, in the case of a VoIP service (the first service) through the Internet, a subscription to a VoIP number is required, thereby increasing the cost additionally. This raises the cost problem of maintaining a fixed telephone number and VoIP number and a mobile communication number.

Therefore, there is a growing interest in wired / wireless integrated services that enable wired / wireless communication with one number.

Wired / wireless integrated call service is a service that allows a user to receive a call service regardless of a wired / wireless network with one number, one bill, and one terminal.

However, the current wired / wireless integrated call service (for example, one-phone service) can use a mobile communication network (CDMA) outdoors, and can use a general telephone network (PSTN) at home, but a landline telephone number can be used when using a wired network. When using a wireless network using a mobile communication number, there is a disadvantage that the handover between the home and the outdoors is not possible. This is merely an implementation of wired and wireless call service depending on the function of the terminal.

For example, the one-phone service has a problem in that the one-phone cannot communicate with an AP other than the AP of the registered home phone. In addition, the one-phone service can be used only in the home where the AP is registered, and when the user goes out of the home (outside the AP area), the mobile phone is unconditionally switched to the mobile phone.

Finally, when a wired telephone connection signal is sent from the service switch (SSP) 43 to the home AP 11, the home AP 11 connects the call with the service terminal 20 to the actual incoming telephone (wired telephone 12). The signal is sent and connected first to the connection (212).

At this time, the ringing rings simultaneously on the actual incoming telephone (wired telephone 12) and the service terminal 20, and the call is first connected to the incoming call (hook-off). For example, when a call-off is received at the service terminal 20, the service terminal 20 which has received an incoming call with an originating phone (any mobile communication terminal via any wired telephone or wired / wireless interworking gateway 32) is received. ). At this time, the outgoing telephone (any mobile communication terminal via a wired or wireless interworking gateway 32) is a state that the call is connected to the service switch (SSP) 43, a separate telephone connection process is not necessary.

On the other hand, although not shown in the figure, looking at the originating process in the service terminal 20, the service terminal 20 is connected to the wired telephone network (PSTN) through the home AP 11, the home AP 11 is This is relayed. Calling by the service terminal 20 is the same as making a call from the landline 12. At this time, the CID shown on the called party (any wired telephone or mobile communication terminal) is a wired telephone number (telephone number of the wired telephone 12) registered in the outgoing service terminal 20.

First, referring to FIGS. 3 and 4, the service terminal 20 is located in the mobile Internet / Wireless LAN region 70 outside the home AP region 10 so that the service terminal 20 becomes a called terminal and a calling terminal. Looking at it as follows.

First, referring to FIG. 3, when the service terminal 20 operates as a called terminal, the service terminal 20 enters into the mobile Internet / Wireless LAN region 70 outside the home AP region 10. The terminal agent 21 of the terminal 20 updates the state of the portable Internet / Wireless LAN 70 with the registration information server 50 (301).

Thereafter, the outgoing telephone (for example, any landline telephone or any mobile communication terminal via the wired / wireless interworking gateway 32) is a landline telephone number (the landline telephone number of the wired telephone 12) subscribed to the service. If the service terminal 20 is registered in the corresponding telephone number (302), the service switch (SSP) 43 of the intelligent network system 40 is the called number (phone number of the wired telephone 12). Based on the check whether the service subscription (303), if the subscriber is a service request to the service controller (SCP) 42 to call (304).

Next, the service controller (SCP) 42 requests the subscriber registration information (registration status information) of the corresponding service terminal 20 to the registration information server 50 through the intelligent network interworking gateway 41 (305). The information server 50 checks the registration information DB 51 (206), and after confirming that the service terminal is connected to the mobile Internet / Wireless LAN, the calling telephone (any wired telephone or mobile communication terminal) and the service. In order to connect the terminal 20, the terminal identifier is assigned to the wireline-Internet gateway 31 (307). In this case, the terminal identifier may be allocated when the service terminal 20 updates the registration information server 50 that the service terminal 20 is in the portable Internet / Wireless LAN region 70 outside the home AP region 10. With this terminal identifier, the service terminal 20 is connected to the wireline-Internet gateway 31 (308), wherein the method of assigning and connecting the terminal identifier may use a session protocol such as SIP.

Subsequently, the registration information server 50 transmits the registration status information indicating that the service terminal 20 is in the portable Internet / Wireless LAN zone 70 and the corresponding terminal identifier to the service controller (SCP) 42 through the intelligent network interworking gateway 41. (309), the service controller (SCP) 42 sends a call connection command for the simultaneous ring with the terminal identifier of the landline-Internet gateway 31 to the service exchange (SSP) 43 (310) The service switch (SSP) 43 transmits the incoming call to the service terminal 20 at the same time through the actual incoming telephone (the wired telephone 12) and the landline-Internet gateway 31 (311).

At this time, the ringing rings simultaneously on the actual incoming telephone (wired telephone 12) and the service terminal 20, and the call is first connected to the incoming call (hook-off). For example, when the service terminal 20 receives an incoming call (hook-off), a call connection is made between the calling telephone (any wired telephone or mobile communication terminal) and the service terminal 20 that has received the incoming call. At this time, since the call is connected to the service switch (SSP) 43, the outgoing telephone (any landline or mobile communication terminal) does not need a separate telephone connection process.

Meanwhile, referring to FIG. 4, a process in which the service terminal 20 operates as a calling terminal will be described. 4 assumes that the service terminal 20 operating as the calling terminal and the calling wireline telephone 11 registered as a service are linked to each other.

When you register for this service, there is a landline telephone number (a telephone number of a wired telephone 11 or other landline telephone (not shown)) to be used.

The registered information DB 51 is mapped with a corresponding landline telephone number (a telephone number of the wireline telephone 11 or other landline telephone) and a terminal identifier assigned to the terminal and the landline-Internet gateway 31, and the calling terminal (service). When making a call from the terminal 20, the landline telephone number (telephone number of the wired telephone 11) in the registration information server 50 is shown on the CID of the other party's telephone (called wired telephone or mobile communication terminal). In this case, the terminal identifier is generated when the service terminal 20 updates the registration information server 50 that the service terminal 20 is in the portable Internet / Wireless LAN region 70 outside the home AP region 10 or generates a request.

If, when calling from the calling terminal (service terminal 20), the called number (phone number of the landline phone registered any service) is a landline telephone number registered in the same service (the caller / called party is both the service subscriber Case), the registration information server 50 checks the registration status of the called terminal (service terminal (not shown in the figure)), and if it is registered, makes a call connection between the service terminals of the originating / receiving terminal. That is, if both originating and terminating terminals are registered, the service terminals attempt to make a call connection (IP network). At this time, a protocol such as SIP can be used.

On the other hand, when the call originating from the calling terminal (service terminal 20) (when the telephone connection request) 301, the called number (any landline phone or mobile phone number of the mobile communication terminal) is not registered in the service, or the called number ( If the telephone number of any landline telephone is registered in the service but the destination terminal (service terminal (not shown)) is not registered, the registered information server 50 is wired to which the service is subscribed in the registration information DB 51. After confirming the terminal identifier mapped to the telephone number (telephone number of the wired telephone 11) (402), after connecting the service terminal 20 to the landline-Internet gateway 31 with the corresponding terminal identifier (403), A call connection request is made to the service controller (SCP) 42 via the intelligent network interworking gateway 41 (404). At this time, the transmitted information includes a terminal identifier (a wired telephone-Internet gateway identifier), a calling party's landline telephone number (a telephone number of the wireline telephone 11) and a called party's telephone number (any landline telephone or a mobile communication terminal number). ).

The service controller (SCP) 42 then causes the service switch (SSP) 43 to make a call to the called telephone (any wired telephone or mobile communication terminal) based on the identifier of the landline telephone-Internet gateway ( 406). At this time, the CID shown on the called party (any landline or mobile communication terminal) is a landline telephone number (telephone number of the wireline telephone 11) registered in the outgoing service terminal 20.

On the other hand, if there is no home AP 11, the service terminal 20 is in the mobile Internet / wireless LAN area 70 outside the home AP area 10, so that the service terminal 20 acts as a called terminal and an originating terminal. It is similar to the case, except that the telephone connection to the landline is directly requested without going through the home AP 11.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

Accordingly, the present invention brings cost savings to users using a voice call service, and brings convenience to make a call on a wired / wireless line using a single number. In addition, the existing landline telephone subscriber only needs to register his terminal to his landline telephone number without a separate subscription process, so that wired / wireless calls can be made at no additional cost.

In addition, according to the present invention, in addition to saving the number resources from the position of the landline telephone operator, there is an effect that can prevent the conversion of the landline telephone to mobile communication.
