1 is a preferred embodiment of the present invention, showing a call rate saving device that automatically performs a call connection attempt with a VoIP phone.

The call charge saving device largely includes a two-number registration unit 110, a search unit 120 and a VoIP switching unit 130.

Terminals with Wi-Fi or Bluetooth functions have the ability to make inexpensive calls through Internet phones in the Wi-Fi or Bluetooth AP area (hereafter, home zone). In other words, in the home zone, it is possible to use a service by accessing a wireless network built by itself using a wireless technology of an unlicensed radio frequency band such as Wi-Fi or Bluetooth.

Therefore, it is possible to make a low-cost call through an Internet phone by using a frequently-placed place such as a home zone, for example, a soft phone in a personal PC or an Internet phone number of a working office desk.

To utilize this feature, the two-number registration unit 110 registers two numbers in one access number while the terminal assigned the VoIP phone number is connected to the wireless IP network, that is, the home zone. Here, the access number is composed of a SIP address accessed by a terminal having an Internet telephone function and a port number used for using an Internet telephone.

In addition, two numbers, two numbers registered in one access number, are each a VoIP phone number (eg, 070-YYY-YYYY) and a mobile communication phone number (eg, 010-XXX-XXXX) corresponding to the VoIP phone number. to be.

Then, the two number registration unit 110 forms a database by using two numbers registered in each phone number. Thus, when searching the database unit, the mobile communication telephone number and the VoIP Internet telephone number corresponding to the access number composed of the IP address and port number to which the user agent (UA) of the Internet telephone is running can be known. At this time, please note that the call originating from the mobile phone number as well as the Internet phone number is registered in the UA of the same Internet phone.

The two-number registration unit 110 may further include an authentication unit (not shown) for determining whether the mobile phone user is a person who subscribes to the call charge saving service of the telecommunication company when registering the two-number. The authentication unit can give incentives to those who subscribe to call rate savings services that automatically attempt to make calls to VoIP phones.

Thereafter, when the caller's Internet phone requests a call to the mobile communication phone number, the searching unit 120 searches whether the mobile communication phone number requested by the caller's Internet phone phone is registered in the database of the two-number registration unit 110. An example of performing the function of the search unit 120 may be a Session Initiation Protocol (SIP) server.

When the mobile phone number requested by the caller's Internet phone is registered in the database of the two-number register 110, the VoIP switching unit 130 accesses the access number corresponding to the mobile phone number (the UA of the Internet phone is running). The call is connected to the corresponding VoIP phone number based on the IP address and the port number).

If the search result of the search unit does not register the mobile communication telephone number requested by the caller Internet telephone in the database of the two-number registration unit 110, the call is connected to the mobile communication telephone number requested by the caller Internet telephone through the mobile communication network. .

2 is a view showing an example of an apparatus for saving call charges, as a preferred embodiment of the present invention.

Examples using the call rate saving configuration described in connection with FIG. 1 include the following examples (210, 220, 230). First, a terminal to which a VoIP phone number is assigned is a dual mode mobile phone 210, in which case the mobile communication phone number corresponding to the VoIP phone number is a mobile communication phone number assigned to the dual mode mobile phone. This will be described in more detail with reference to FIGS. 3 to 4.

Next, the terminal to which the VoIP telephone number is assigned is the soft phone 220, and the mobile communication telephone number corresponding to the VoIP telephone number is the mobile communication telephone number of the user who uses the soft phone. If it is possible to check whether the user is connected to the Internet through a soft phone, when the call comes from the Internet phone, the call to the mobile phone number can be automatically converted to the soft phone to reduce the call charge.

In another embodiment, a terminal to which a VoIP phone number is assigned is an Internet phone 230 of a user who uses a cellular phone having an RFID tag, and a mobile communication phone number corresponding to the VoIP phone number is attached to the RFID tag. In the case of a mobile phone number.

When the location determined using the RFID tag is within the wireless IP network, the VoIP switching unit connects the call to the VoIP phone number, and when the user is out of the home zone, the call can be connected to the mobile communication phone number to save the charge. . In this case, authentication information about whether the user subscribes to the rate saving service may be checked in the same manner as the home zone registration proxy server 241 and the save rate user DB 242.

When a user registers an internet phone number that can be used in a wireless network by using a tag having a location tracking service function, the location tracking service may be performed using a technology such as WLAN or Zigbee.

For example, if you register the number of your desktop Internet phone in the office with the location service system, you can receive mobile phone charge saving service if you are not at the office desk. I can receive it with an Internet telephone,

3 illustrates, as one preferred embodiment of the present invention, a dual mode terminal that automatically performs a call connection attempt with a VoIP telephone.

As a preferred embodiment of the present invention, the dual mode terminal automatically performs a call connection attempt with a VoIP phone when an outgoing call comes from an Internet phone. In general, the dual mode terminal is a two number type having a mobile communication telephone number and an Internet telephone number.

Anyone who uses an Internet phone pays a very low call fee when dialing an Internet phone number when making an outgoing call to a dual mode phone user, but pays an expensive mobile phone call fee when calling a mobile phone number.

Therefore, in the present invention, even if the caller's Internet phone dials the mobile phone number to the dual mode phone user, if the dual mode phone user is located in the home zone, the mobile phone will automatically dial to reduce the phone call charges.

When a user using a dual mode phone is connected to an access point (AP) capable of serving in a home zone, a call from an Internet phone is connected to a VoIP phone number in the home zone. In this case, compared to the current mobile phone call rate (average 18 won per 10 seconds), the PSTN number is available at 1/8 level on a three-minute call basis, and, in the case of an Internet phone, Internet services can be used free of charge.

When the dual mode phone leaves the home zone, the default outgoing call means is automatically changed to the mobile communication telephone number.

To this end, as a preferred embodiment of the present invention, a dual mode terminal that provides automatic VoIP switching to reduce call charges includes a two-number register, a search unit, and a VoIP switching unit.

The two-number registration unit configures a database by registering a two-number consisting of a VoIP phone number and a mobile communication phone number in a connection number consisting of a connected SIP address and a port number while the dual mode terminal is connected to a wireless IP network.

When the caller makes an outgoing call from the caller's Internet phone to the mobile communication phone number, the searcher searches whether there is a mobile communication phone number that has been called in the database configured in the two-number register.

Thereafter, if there is a corresponding mobile communication phone number in the database as a result of the search, the call is connected to the VoIP phone number corresponding to the mobile communication phone number through the access number of the two-number register. For a more detailed description related to this, refer to the description of the call charge saving device described above with reference to FIGS. 1 and 2.

As shown in FIG. 3, the SIP proxy server that performs the function of the search unit registers two numbers for each access number in the location registration server 320 in the two number registration client 310 when a call comes from the caller's Internet telephone. After searching the created database, if there is a phone number in the database, attempts to connect through the Internet telephone network 340, if there is no phone number in the database, attempts to connect through the mobile communication network 350 do.

The two-number registration client 310 registers a two-number consisting of a VoIP telephone number and a mobile communication telephone number in the access number while the dual mode terminal is connected to the wireless IP network, that is, the home zone. In this case, the two number registration client 310 can be implemented in the Internet phone UA. Additionally, the two number registration client 310 includes an agent function for communicating with the location registration server 320.

Whether the terminal has deviated from the wireless IP network can be determined periodically by not transmitting a message transmitted from the location registration server 320 to the two-number registration client 310, in which case the data registered in the location registration server 320 Exclude the corresponding telephone number and access number from the number.

4A illustrates an example of automatically making a call connection attempt with a VoIP phone in a dual mode terminal according to an embodiment of the present invention.

The two-number registration client 410 registers the mobile communication number 010-xxx-xxxx number with the location registration server 420 together with the VoIP phone number, which is the Internet telephone number, in the access number when the dual mode cellular phone is in the home zone.

Then, if the caller's Internet phone dialed the 010-xxx-xxxx mobile phone number, the SIP proxy server 410 searches for the 010-xxx-xxxx mobile phone number on the location registration server 420, If it exists as in this case, it receives and receives a connection from an Internet phone of a dual mode mobile phone through an Internet phone network.

4B illustrates an example of performing a connection to a mobile communication network when a call cannot be connected to a VoIP phone in a dual mode terminal according to an embodiment of the present invention.

In the environment similar to that of Fig. 4A, when the dual mode cellular phone leaves the home zone (511), the location registration server 520 does not register the 010-xxx-xxxx mobile communication phone number, so that the SIP proxy server 530 Since the location registration server 520 cannot retrieve the 010-xxx-xxxx mobile phone number, since the connection from the dual mode mobile phone to the Internet phone number is not possible, the mobile phone network 550 immediately tries to connect to the phone connection. Minimizes the impact.

5 shows an advantage when using the call charge saving apparatus of the present invention.

As shown in Figure 2, user A's dual-mode mobile phone user used the service provider's service to provide the service using the present invention to the mobile phone number 010-xxx-xxxx, but 2 minutes to the Internet phone number 070-yyy-yyyy If he talks for 30 seconds, A can save 90 won. In addition, incentives of KRW 15 can be provided to those who subscribe to the rate-saving service.
