Referring to FIG. 1, an Internet private switching system includes a terminal 100, an Internet private branch exchange 200, and a registration server 300.

The terminal 100 may be a smart phone, for example, a terminal capable of Internet communication. The terminal 100 transmits and receives a call using an alias instead of an extension number.

Such a terminal 100 may include a communication unit 101, a storage unit 103, a display unit 105, and an extension call processing unit 107 in detail.

The communication unit 101 performs communication connected to the Internet private branch exchange 200.

The storage unit 103 stores an extension user list consisting of user nicknames registered in the private Internet switching network, i.e., the registration server 300, and extensions matched to user nicknames.

The display unit 105 displays an extension user list in which user nicknames are listed on the screen.

The extension call processing unit 107 obtains the extension number corresponding to the alias selected by the user from the extension user list from the storage unit 103 and requests the extension using the extension number. Or if a call request is received, acquires an alias corresponding to the extension number from which the call request is transmitted from the storage unit 103 and outputs the obtained alias to the display unit 105. [

The extension call processing unit 107 generates a URL for requesting an extension user list including the extension number and the terminal unique information allocated to the user according to a user request and transmits the URL to the private Internet exchange 200. Then, the list of station users whose nicknames and extensions of the registered users are matched is received and stored in the storage unit 103. And outputs the registered alias users' nicknames to the display unit 105.

The registering unit 109 allocates an extension number by transmitting the nickname and the terminal specific information input by the user at the time of registering the extension user, and stores the allocated extension number in the storage unit 103 together with the nickname inputted by the user. The terminal unique information is used to confirm whether or not the terminal 100 is assigned an extension number. Here, the terminal specific information may be a MAC (Media Access Control) address of the terminal.

The registration unit 109 transmits the authentication number input by the user at the time of the extension user registration, and the authentication number is used as the identification information for limiting the extension user registration to only the authorized user. Here, the authentication number may be the identification information of the registration server 300.

The registration unit 109 generates and transmits a URL (URL) for the extension user registration.

The registration unit 109 may store unique information of a wireless router (not shown) that performs both functions of the Internet private branch exchange 200 and the registration server 300 that performs extension user registration together with an assigned extension number. Here, the unique information includes a service set identifier (SSID) and a basic service set (BSSID). The unique information of the wireless router (not shown) is obtained by connecting the terminal 100 to a wireless router (not shown) that provides a priority service when the terminal 100 enters a service area of a wireless router (not shown) .

The registration unit 109 receives the assigned extension number and the assigned password from the registration server 300, matches the assigned extension number with the assigned password, and stores the same in the storage unit 103.

At this time, the extension call processing unit 107 and the registering unit 109 may be implemented by a processor.

In addition, the Internet private branch exchange 200 stores an extension number allocated to the terminal 100 and controls an Internet call between the terminals 100 using the extension number.

The Internet private branch exchange 200 stores an extension number assigned by the registration server 300. And transmits the extension number and the password assigned by the registration server 300 to the terminal 100 of the extension user.

The registration server 300 allocates and manages an extension number for each alias set by the terminals 100.

When the user registration request including the alias name and the terminal unique information inputted by the extension user is received from the terminal 100 of the extension user, the registration server 300 identifies the duplication request based on the terminal unique information, , And assigns an extension number to the nickname inputted by the extension user and stores the extension number, and transmits the assigned extension number and the generated password to the Internet private branch exchange 200.

When receiving an extension user list request from an extension user terminal 100, the registration server 300 generates an extension user list including an extension number matched to the alias and alias of the registered extension users, and transmits the extension user list to the terminal 100 do.

The registration server 300 receives a URL (URL) for requesting an extension user list including the extension number and the terminal unique information from the terminal 100 of the extension user. Then, based on the terminal-specific information, it is confirmed whether it is an extension user registrant, and then an extension user list is generated.

As described above, when the user registers in the Internet private exchange network, the private key exchange system according to the embodiment of the present invention registers a desired nickname in the registration server 300 and provides the user with a nickname service in addition to the number.

Connection information such as nicknames and extension numbers of users registered in the Internet private exchange network is automatically called from the registration server 300 at the request of the user and displayed on a device having a display such as a smart phone Is possible.

2, the terminal 100 transmits a registration request of an alias (User 1) input by the user to the Internet private branch exchange 200. 2. The Internet private branch exchange 200 transfers the registration request to the registration server 300. 3. The registration server 300 assigns an extension number (1) to an alias (user 1) requested by the terminal 100, and then completes user registration. 4. The Internet private branch exchange 200 stores the assigned extension number 1 and then transmits the extension number 1 allocated to the terminal 100. [ This user registration process will be described in detail in detail in FIG. In particular, FIG. 3 shows a procedure of accessing a user's Internet telephone equipment using SIP, which is one of protocols for using a VoIP service, to an Internet private exchange network using an assigned extension number and a password.

Referring to FIG. 3, a user who intends to register in the Internet PSTN in the terminal 100 inputs a desired nickname and an authentication number (S101). Here, the authentication number is used to limit the registration of unauthorized users by a unique identification number of each registration server 300.

The terminal 100 extracts the MAC address of the terminal (S103), and generates a URL (URL) for requesting registration together with the received information in operation S101 (S105). Then, when attempting to access the registration server 300 using the generated URL (URL), the registration request is transmitted to the Internet private switching center 200 (S107). Then, the Internet private branch exchange 200 transfers the registration request to the registration server 300 (S109).

The registration server 300 checks whether the authentication number is valid (S111, S113), and if not, returns a registration failure response (S115, S117).

On the other hand, if the authentication number is valid, it is checked whether the MAC address is duplicated or not and it is determined whether the MAC address is already registered (S119).

If it is not registered, an arbitrary extension number and a secret number are generated and stored in association with the alias transmitted in step S109 (S121).

On the other hand, if the device is already registered, the allocated extension number is used and the password is regenerated, and then stored in association with the alias transmitted in step S109 (S123).

Next, the registration server 300 transmits the user registration completion including the extension number and the password to the Internet private branch exchange 200 (S125). Then, the Internet private branch exchange 200 stores the extension number and transmits the completion of user registration to the terminal 100 (S127).

The terminal 100 stores the extension number and the password received in step S127 (S129). After storing the SSID and the BSSID of the wireless router in step S131, the controller transmits a REGISTER (SIP) message in step S133 and then receives a 200 OK (SIP) message in step S135.

4, the terminal 100 transmits an extension user list request. 2. The Internet private branch exchange 200 transmits an extension user list request transmitted by the terminal 100 to the registration server 300. 3. The registration server 300 generates an extension user list whose nickname is matched with the extension number and transmits the list to the PSTN 200. At this time, the extension user list is updated each time it is requested. 4. The Internet private branch exchange 200 delivers the extension user list to the terminal 100. Then, the terminal 100 displays a list of extension users whose nicknames are listed. The process of providing the extension user list will be described in detail in the order of FIG. 5

5, when the extension list is deleted or a user request is generated, the terminal 100 extracts the extension number and the MAC address of the terminal 100 (S201) and generates a URL for requesting the extension user list (S203). The reason for including the extension number and the MAC address in the URL is to distinguish whether the person requesting the extension user list is a registered user in the registration server 300. Then, when attempting to connect to the URL generated by the terminal 100, the registration request is transmitted to the Internet private branch exchange 200 (205).

The Internet private branch exchange 200 transmits an extension user list request to the registration server 300 (S207).

The registration server 300 checks whether the user is registered based on the MAC address included in the extension user list request transmitted in step S207 (S209). At this time, if it is an unregistered person, a step of guiding registration may be further performed.

The registration server 300 generates an extension user list in which registered nicknames and assigned extension numbers are matched with each other (S211), and transmits the list to the Internet private branch exchange 200 (S213). Then, the Internet private branch exchange 200 transmits the extension user list to the terminal 100 (S215).

The terminal 100 stores the received extension user list (S217). Then, an extension user list in which only nicknames are listed is displayed on the screen (S219).

FIG. 7 is a flowchart illustrating an extension call connection procedure using an alias according to an embodiment of the present invention. to be.

Referring to FIG. 6, a service connection between users using nickname lists of Internet private exchange network users acquired through FIG. 5 is shown. 1. In the terminal 100, the user selects a nickname of a partner to which the service is to be connected from among the extension user list, and requests the service. Then, the terminal 100 requests the service of the Internet private branch exchange using the SIP as the extension number corresponding to the alias selected by the user. The service utilization process of the Internet private branch exchange is as shown in FIG.

At this time, the terminal 100 will be described as a calling terminal requesting a service connection and a called terminal requesting a service connection.

Referring to FIG. 7, in step S301, the calling terminal 100 converts a selected nickname to an extension number in step S303 when a user event in which an arbitrary nickname is selected from an extension user list is requested to request an extension phone connection. That is, an extension number corresponding to the selected nickname is acquired from the storage unit 103.

The calling terminal 100 generates an INVITE message for requesting a telephone connection to the converted extension number in step S303 (S305), and transmits the INVITE message to the Internet private branch exchange 200 (S307). The Internet private branch exchange 200 transmits an INVITE message to the called terminal 100 (S309).

The calling terminal 100 extracts the calling number from the INVITE message (S311). Then, the calling number is converted into an extension number (S313), the alias matching the extension number is obtained from the storage unit 103 and outputted to the screen (S315). That is, the caller is displayed as an alias rather than a number.

Thereafter, when a call response input of the called party occurs, a response signal 100 Trying (SIP) is transmitted to the calling terminal 100 through the private branch exchange 200 (S317) (S319).

Then, a 180 Ringing (SIP) message is transmitted from the receiving terminal 100 to the calling terminal 100 (S323) through the Internet private branch exchange 200 (S321). In addition, a 200OK (SIP) message is transmitted from the receiving terminal 100 to the calling terminal 100 via the private branch exchange 200 (S325) (S327).

Then, a response signal (ACK (SIP)) is transmitted from the calling terminal 100 to the called terminal 100 via the Internet private branch exchange 200 (S329) (S331).

Thereby, a media session is established between the calling terminal 100 and the called terminal 200 (S333) to make a call.
