Abstract

The present invention is an IP phone number management system for managing the IP phone number changed to a naming server using a single ID of the IP phone user, instead of notifying callers of the IP phone number that changes frequently when using an IP phone in a wireless network. And a method, which has conventionally been inconvenient to notify other people whenever an IP phone number is changed to update the changed IP address or phone number, and the IP phone user does not know the IP phone number of the callee. In this case, it was necessary to make a phone call by directly inputting it. In particular, when the IP phone number of the callee was changed, it was inconvenient to find out and make a call using another method.

Therefore, the present invention registers and manages its own IP phone number with a single ID in the naming server at the time of initialization of the IP phone, so that even if the corresponding IP phone number is changed, it is not necessary to inform others, and make a call. The IP phone user who owns the call can obtain the caller's IP phone number from the naming server and make a call even if the callee's IP ID is changed.

Description

System and Method For IP Phone Number Management

The present invention relates to an IP phone number management system and method, and in particular, IP phone number that is changed by using a single ID of the IP phone user instead of notifying callers of the IP phone number that changes frequently when using an IP phone in a wireless network. The present invention relates to an IP phone number management system and method for managing a naming server.

In general, Voice over IP (VoIP) service, which enables data and voice calls using Internet Protocol (IP), which is the standard protocol in the network, integrates telephone service by utilizing existing IP network and transmits telephone or fax. By reducing the line cost, the phone users can receive long distance and international phone service as well as data service in the Internet and intranet environment with only local call charges.

IP phone, which is a user terminal supporting the VoIP service, has an application program such as an address book or a phone book, and the user registers the IP addresses or phone numbers and names of others in advance through the application. In order to make a call, the registered information is retrieved and the other party's IP address or phone number is obtained.

At this time, as shown in Figure 1, the call processing unit of the corresponding IP phone (11-1 ~ 11-n) through the IP network using the IP address or phone number of the other party obtained by searching the content registered in the application program The user of the other IP phones 11-1 to 11-n may talk with the user of the general telephone 12 through the IP network and the public switched telephone network (PSTN) network.

When using IP phones 11-1 to 11-n in a mobile network, every time the IP address or phone number is changed, other people are notified to update the changed IP address or phone number. I had to.

On the other hand, the conventional IP phone user has to make a call by directly inputting the IP address or phone number of the other party to make a call, and in particular, the IP of the other party to make a call. If the address or phone number has been changed, it was inconvenient to find out and make a call through other methods.

The present invention has been made to solve the above-mentioned problems, and its object is to register and manage its own IP phone number with a single ID in the naming server at the time of initialization of the IP phone, if the corresponding IP phone number is changed The IP phone user who wants to make a call while removing the inconvenience of notifying other people can obtain the caller's IP phone number from the naming server even if the caller's IP ID is changed if the caller's single ID is known. To make the call.

Preferably, if the transmitted single ID does not exist in the database, the phone number manager requests a callee's IP phone number by transmitting a single ID to a higher naming server until the caller's IP phone number is obtained. It characterized by repeating the steps.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The IP address or telephone number (hereinafter referred to as 'IP phone number') management system for the IP phone according to the present invention, as shown in Figure 2, a plurality of IP phones to which different IP phone numbers are assigned (21-1 to 21-n) and a number of naming servers (Naming Server, 23-1 to 23-n) that provide a naming service, each IP phone (21-1 to 21-n). n) is provided with a naming resolving unit 21-1a to 21-na and a naming registration unit 21-1b to 21-nb which are application programs having a predetermined function, respectively. The server 23-1 to 23-n includes a phone number manager 23-1a to 23-na and a database for managing IP phone numbers for local IP phones 21-1 to 21-n. (23-1b to 23-nb) is included.

The naming registers 21-1b to 21-nb of the IP phones 21-1 to 21-n perform local naming of their IP phone number and a unique ID (e.g., an email address, etc.) upon initialization. The server 23-1 sends a request for registration, and the naming resolvers 21-1a to 21-na use the single ID input from the user to obtain the IP phone number of the callee. Send a single ID to -1) to request the IP phone number.

The phone number manager 23-1a of the naming server 23-1 transmits an IP phone number and a single ID from the naming registers 21-1b to 21-nb of the IP phones 21-1 to 21-n. Register the database 23-1b to 23-nb, search the database 23-1b to 23-nb, and search for the naming decomposition unit 21-1a to 21 of the IP phones 21-1 to 21-n. If a single ID transmitted to obtain an IP phone number from -na is present in the databases 23-1b to 23-nb, the IP phone number corresponding to the single ID is determined by the naming decomposition unit 21-1a to the IP phone. 21-na), but if a single ID sent to obtain the corresponding IP phone number does not exist in the databases 23-1b to 23-nb, a single ID is sent to the upper remote naming server 23-n. Send and request the corresponding IP phone number.

The databases 23-1b to 23-nb of the naming servers 23-1 to 23-n store IP phone numbers corresponding to single IDs of the respective IP phones 21-1 to 21-n. have.

On the other hand, the IP phone number management operation according to the present invention is a procedure for registering the IP phone number to the corresponding local naming server (23-1 ~ 23-n) at the time of initialization, and the corresponding IP phone number naming server (23-1 ~) 23-n) receives a caller's single ID and registers the corresponding IP phone number from the naming servers 23-1 to 23-n to process the call. The phone number management operation is described in detail with reference to FIG. 3 as follows.

First, IP phones 21-1 to 21-n connected to the IP network must register the IP phone number with the local naming server 23-1 using their single ID (step S31). At the time of initialization of 21-1 to 21-n), the naming register 21-1b to 21-nb checks whether a fixed IP phone number is assigned to itself, and if the fixed IP phone number is assigned to itself, It sends a single ID and IP phone number such as e-mail to the local naming server 23-1 to which it belongs and requests registration.

However, if a fixed IP phone number is not specified, the IP phone number is dynamically assigned according to the IP network configuration to which the IP phone number belongs. Then, the assigned dynamic IP phone number is assigned to the local naming server 23-1 with a single ID. In this case, the IP phone 21-1 to 21-n transmits a single ID and the changed IP phone to the local naming server 23-1 whenever its IP phone number is changed. The IP phone number can be updated by transmitting the number.

Accordingly, the phone number manager 23-1a of the local naming server 23-1 stores the single ID and IP phone number received from the IP phones 21-1 through 21-n in the database 23-1b through 23-. nb) stored in the registration, and when the registration is completed, the IP phones 21-1 to 21-n are notified that the registration is normally completed.

If the IP phone user inputs a single ID of the callee who wants to make a call while registering the IP phone number through the above procedure (step S32), the naming decomposition of the corresponding IP phones 21-1 to 21-n is performed. The parts 21-1a to 21-na transmit the single ID inputted to the local naming server 23-1 to which they belong in order to obtain the IP phone number of the called party and request the IP phone number of the called party ( Step S33).

Accordingly, the phone number management unit 23-1a of the corresponding local naming server 23-1 searches the database 23-1b to obtain the IP phone number of the callee and the IP phones 21-1 to 21-n. It is checked whether or not a single ID transmitted from the naming decomposition units 21-1a to 21-na in the database exists in the corresponding databases 23-1b to 23-nb (step S34).

At this time, when a single ID exists in the databases 23-1b to 23-nb, the phone number manager 23-1a withdraws the IP phone number corresponding to the single ID from the databases 23-1b to 23-nb. The IP phone numbers are returned to the naming resolution units 21-1a to 21-na of the IP phones 21-1 to 21-n that have requested (step S36).

However, if a single ID transmitted to obtain an IP phone number does not exist in the databases 23-1b to 23-nb, the corresponding IP phone number is transmitted by transmitting a single ID to the upper remote naming server 23-n. Is requested (step S35).

Then, the phone number manager 23-na of the upper remote naming server 23-n, like the phone number manager 23-1a of the local naming server 23-1 described above, sets the IP phone number of the callee. After checking whether the single ID transmitted from the lower naming server 23-1 exists in the database 23-1b managed by the user (step S34), if the single ID exists, the IP corresponding to the single ID exists. When the phone number is withdrawn from the database 23-1b and returned to the IP phones 21-1 to 21-n through the lower naming server 23-1 (step S36), a single ID does not exist. In order to request a corresponding IP phone number by transmitting a single ID to a higher remote naming server, this operation is performed by the naming decomposition parts 21-1a to 21-na of the IP phones 21-1 to 21-n. Repeat the process until you get the IP phone number of the callee you want to get.

That is, the corresponding naming servers have a hierarchical structure as shown in FIG. 4. The upper naming server receiving the single ID requesting the IP phone number of the callee from the local naming server has a lower structure. After checking whether the single ID transmitted by the remote naming server of the database exists, if the single ID exists, the IP phone number corresponding to the single ID is returned to the lower remote naming server, but the single ID exists. If not, the operation of requesting the IP phone number by transmitting a single ID to a higher remote naming server as described above until the IP phone number of the callee who wants to obtain the IP phone number is obtained. Repeatedly, there is a single ID entered in any naming server with hierarchical structure. If you do not have an IP phone number searches will return an error information.

On the other hand, when the IP phone number is returned from the phone number management units 23-1a to 23-na of the naming servers 23-1 to 23-n, the call processing unit of the IP phones 21-1 to 21-n returns. By performing the call processing with the call recipient using the IP phone number (step S37), the call service can be provided to the IP phone user.

As described above, in the present invention, by initializing the IP phones 21-1 to 21-n by registering and managing their IP phone numbers with the single IDs to the naming servers 23-1 to 23-n, If you want to make a call, if you know only the single ID of the callee, even if the IP phone number is changed, the phone can obtain the changed IP phone number through the naming servers 23-1 to 23-n.

In addition, the embodiments according to the present invention are not limited to the above-described embodiments, and various alternatives, modifications, and changes can be made within the scope apparent to those skilled in the art.

As described above, the present invention registers and manages its own IP phone number with a single ID in the naming server at the time of initialization of the IP phone, so that even if the corresponding IP phone number is changed, it is not necessary to inform others. If the IP phone user who wants to make a call knows the single ID of the callee, the callee can obtain the callee's IP phone number from the naming server even if the callee's IP phone number is changed.
