Description

Internet phone service system using UMS and method for providing the service

The present invention relates to a system and method for connecting a plurality of UMS servers through an Internet protocol network.

UNIMSIE MESSAGING SYSTEM (UMS) is a system that provides unified messaging service. Users can use this UMS to transmit data regardless of communication media such as telephone, fax and e-mail. The present invention is not limited to the type of medium, and data can be received through a desired communication medium.

An example of a unified messaging service using UMS is a service that checks messages by phone.

First, the caller leaves a message in UMS via phone, fax, or the web. The message can be sent by the caller by calling the UMS, leaving the voicemail or phone number to the called party, by calling the UMS via fax, by faxing the called party, or by sending the email to the called party via the web. have.

The UMS notifies the called party by email or mobile phone when a new message arrives. When the called party requests to check the message by accessing the UMS by telephone, the UMS can convert the e-mail into voice using TTS, read it by telephone, and convert it into a document using TTF and transmit it by fax.

In addition, UMS allows the sender to send a fax to the called party without a fax.

When the sender creates a document on the web and inputs the recipient's fax number into the UMS, the UMS notifies the recipient's email or mobile phone, converts the email into a document by TTF, and sends it to the recipient's fax.

In addition, when a caller leaves a message to UMS via fax or web, UMS notifies the recipient's mobile phone or e-mail, and when the caller accesses UMS via web, UMS converts the fax document to be checked on the web. To receive faxes over the Web.

Also, if you record voicemail on the web and specify the called party's phone number and send it to UMS, UMS will call the designated phone number and listen to the recorded message. It provides a variety of unified messaging services, including support for verifying voicemails.

UMS providing such a unified messaging service is increasing, but each is operating independently of each other. If the UMS server is connected, subscribers who are subscribed to different UMS servers can communicate by using IP network which is low in communication service fee. Since such system is not proposed, communication between subscribers subscribed to UMS server belonging to different countries When you do, even though each of them is subscribed to the UMS server has a problem of communicating over expensive international public telephone network.

On the other hand, in order to use such a UMS, both the calling party and the receiving party must be aware of the unique UMS number assigned by each user in the UMS. There is a problem that you need to teach the UMS number separately.

Currently, the automatic call forwarding service provided by a company such as Korea Telecom is provided. However, the automatic call forwarding service is connected through a public telephone network, and an expensive fee is charged in the case of an international connection with a long distance between regions. .

Accordingly, an object of the present invention is to solve the above problem, and an object of the present invention is to connect one or more UMS servers through an inexpensive IP network so that UMS subscribers can use an Internet phone service through a phone TO phone. It is to provide a system and method.

In addition, the present invention provides a subscriber automatic subscription service to the subscribers subscribed to the UMS server to support subscribers subscribed to different UMS server to communicate using the existing media number without managing a separate UMS number It is another object to provide the system and method.

In order to use a unified messaging service for telephone, fax, and email transmission through a system according to the first embodiment of the present invention, a user first accesses an Internet site operated by a UMS server through a computer, registers as a member, and uses a UMS. The process of receiving the unique UMS number assigned by the server must be preceded.

When accessing the UMS server 100 through a terminal such as a computer and inputting member information, the UMS server associates the registered user information with the corresponding unique UMS number and stores it in the UMS number storage unit 70. .

The UMS server 100 receives and stores a communication medium number for which a member wishes to provide a unified messaging service. This is the case when a member enters a mobile communication number inputted to receive a fax reception guide text message, which may be configured in the same manner as a conventional UMS server.

The present invention supports an international communication service through a remote UMS server to an existing unified messaging service. The UMS server classifies and stores UMS numbers of members managed by other UMS servers connected through an IP network by UMS server. It features.

In the method of connecting a telephone call through a plurality of UMS server network systems according to the first embodiment, as shown in FIG. 3, when the caller inputs his or her UMS number by telephone, the caller's UMS number is passed through the gateway and the local telephone network. It is connected to the first UMS server 100a in charge of. In order to receive the member service, if a caller registered in the first UMS server inputs a password, the password inputted by the caller is transmitted to the first UMS server 100a. (C1)

The first UMS server 100a retrieves the data stored in the storage unit, authenticates the member, and transmits the member service menu to the caller's phone.

The caller requests an international telephone connection service according to the present invention from the member service menu, and requests an incoming call to a UMS number that is in charge of another UMS server, such as another country. (C3)

The first UMS server 100a receives the called party's UMS number requested by the caller, retrieves the stored UMS number for each UMS server, searches for a second UMS server that is in charge of the called party's UMS number among the plurality of UMS servers, and the second UMS server. The called party's UMS number is transmitted to the server 100b via the IP network (C5).

Since each UMS server is operated independently when using an existing UMS server, when a user attempts to make a call with a subscriber of a UMS server belonging to another country, the user is connected through a public telephone network, and the billed international telephone fee is charged. I had to pay.

In the embodiment according to the present invention, as described above, since a plurality of UMS server is connected through the IP network, even if the caller and the receiver is a member of a UMS server belonging to a different country, the international telephone call by paying a low IP network fee You may be offered a call.

The second UMS server 100b receives the UMS number transmitted through the IP network from the first UMS server 100a, calls the called party's telephone number corresponding to the transmitted UMS number, and (C6) the local telephone network and the gateway. Connecting (C7), and connecting a call between the calling party and the called party.

When the called party's UMS number is its own UMS number, the second UMS server 100b means the first UMS server.

In the fax transmission method through the plurality of UMS server network system according to the first embodiment of the present invention, as shown in FIG. 4, a sender registered in the first UMS server 100a transmits the sender's UMS number and password. (C11), authenticate your membership (C12)

When the authenticated caller selects the international fax transmission service among the member services provided by the first UMS server 100a, inputs the destination UMS number, and enters the fax contents, the input UMS number and the fax contents are transmitted through the local network. It is transmitted to the server 100a. (C13)

The first UMS server stores the transmitted fax content (C14), and grasps the second UMS server 100b in charge of the called party's UMS number (C15).

The first UMS server 100a transmits the UMS number of the called party and the fax contents to the second UMS via the IP network (C16).

The second UMS server 100b grasps the called party's media number corresponding to the called party's UMS number (C17), and transmits the fax contents to the called party's fax machine via the local network (C18).

By converting the fax content into a suitable form according to the method set in advance by the called user, the integrated messaging service provided by the conventional UMS server can be provided. For example, by converting the fax content into a short text message through SMS, it can be sent to the mobile communication phone number set by the called user (C20), or the fax content can be sent by e-mail set by the called user. C21) In addition, when the called party connects to the second UMS server 100b via the Internet or telephone and requests to receive the fax contents, the fax contents converted to voice using the TTS 87 are provided by web mail or telephone. can do. The present invention manages the transmission and reception of data between several UMS servers, and is not limited to the integrated messaging service system in charge of such a conventional UMS server.

The first UMS server 100a or the second UMS server 100b may be in charge of appropriately converting the fax contents between the UMS servers according to the storage or reception medium of the fax contents. The present invention is not limited to such a work distribution method.

If the calling first UMS server is in charge, the first UMS server 100a stores the fax contents input by the sender, converts them into a suitable form, and sends a signal notifying the fact that the fax is stored to the second UMS server 100b. When the second UMS server 100b receives a request from the called party, the second UMS server 100b may access the first UMS server, retrieve the fax contents converted by the first UMS server 100a, and transmit the received fax contents to the called party.

Similarly, when the second UMS server 100b is in charge, the 1UMS server 100a transmits the contents of the fax to the second UMS server 100b, and the second UMS server 100b converts the transmitted fax contents into a suitable form. And store the service according to the request of the called user.

Since the email transmission method through the plurality of UMS server network systems according to the first embodiment of the present invention is similar to the fax transmission method, the drawings will be omitted.

The e-mail transmission method, like a telephone or a fax, is preceded by a member registration process in the UMS server.

After the caller accesses the 1UMS server through the Internet network through a terminal such as a PC and receives member authentication, when the caller enters the destination UMS number and e-mail, the 1UMS server 100a stores the e-mail contents. The second UMS server 100b in charge of the called party's UMS number is identified.

When the first UMS server 100a transmits the mail contents to the second UMS server 100b via the IP network, the first UMS server 100a may use a method of transmitting all mail contents together with the destination UMS number and a simple notification method of mail reception history. have. When all the mail contents are transmitted, the second UMS server 100b transmits the mail contents by an e-mail corresponding to the corresponding called party's UMS number.

When the first UMS server notifies the reception of the mail, the second UMS server 100b accesses the first UMS server through the IP network when the recipient receives a request for receiving an email, and retrieves the mail stored in the first UMS server 100a. Can be provided to the called party.

In addition, the second UMS server 100b transmits a short email reception message to the called party's mobile LCD screen through SMS, converts the email to voice via TTS, and provides a voice message when the called party requests to listen to the email. It is desirable to support a variety of unified messaging services such as.

As described above, the first embodiment according to the present invention is a case where a user is provided with a service by managing a unique UMS number, which is separately provided. In order to use a service, a UMS number is separately managed through a UMS server. In other words, other users must be aware of the UMS number.

In the integrated messaging service method, which is automatically connected to the incoming call through the plurality of UMS server network systems according to the second embodiment of the present invention, the user does not manage a separate UMS number separately, It is to use the same number as used to provide the Unified Messaging service.

The second embodiment of the present invention is a method of linking an existing incoming automatic connection system to the UMS server network system of the first embodiment.

5 is a flowchart illustrating a registration process for applying for an incoming call automatic connection.

When a user connects to the UMS server and applies for membership registration, communication media such as member's personal information, password for membership authentication, wired / wireless telephone number, fax number and e-mail address to receive the service. Enter a number. Such a media number, which the user has previously used, will be referred to as an existing communication media number (S10).

The UMS server determines whether the user who inputs the existing communication medium number selects the incoming call connection service (S12). If the user does not select it, the UMS server provides the service of the first embodiment by assigning and managing the UMS number for each member.

If the user selects the incoming automatic connection service, the UMS server assigns each member's UMS number, and automatically connects the incoming UMS number and the existing communication medium number entered by the user. (S16) The incoming call connection service may be configured in the same manner as provided by the Korean telecommunications and the company, which is a part that can be implemented by those skilled in the art. Existing companies, such as Korea Telecom, use a public telephone network to transmit data, so the communication fee varies according to the distance. However, the present invention is because the UMS server connected through the IP network provides self-routing service by itself. Regardless of distance, it is automatically connected to incoming call through cheap IP network.

The UMS server notifies the newly assigned UMS number to other UMS servers connected and communicated through the IP network, and provides a plurality of UMS numbers in charge thereof (S18).

In the same manner, when the newly assigned UMS number is notified from another UMS server, the UMS number is classified and stored according to the UMS server managing the transmitted UMS number (S20).

In the above-described case, in order to communicate with other UMS servers, a method of classifying and storing UMS numbers managed by other UMS servers for each UMS server has been described. However, codes for recognizing a UMS server for the UMS number itself given to a user are described. You can also use the way to give. The present invention is not limited to the method of identifying the corresponding UMS server through the UMS number.

As a second embodiment according to the present invention, as a method of linking a plurality of UMS server network automatic incoming connection system and the incoming automatic connection system, it provides a unified messaging service including a telephone, a fax, an email.

For convenience of explanation, a telephone call method will be described.

6 is a flowchart showing a telephone call method of the second embodiment.

It is assumed that the sender and the called party are members who applied for the automatic incoming connection service as described above in the first UMS server 100a and the second UMS server 100b, respectively.

When the caller enters the caller's telephone number, (C21) the incoming call is automatically connected to the first UMS server 100a. (C22) The first incoming UMS server connected to the incoming call authenticates the user through the same information. C23)

When a caller requests an international call connection service from among the unified messaging services provided by the first UMS server and inputs a general telephone number of the called party instead of the UMS number of the called party, (C24) the called party's general telephone number and the automatic called party The incoming call is automatically connected to the second UMS server 100b via the IP network through the connected UMS number.

The second UMS server 100b connects to the called party's phone through the local public telephone network (C26), and a telephone call is connected between the caller and the called party (C27).

If the called party is not answered, the voice message can be recorded by the unified messaging service provided by the UMS server. (C28) The second UMS server 100b stores the caller's voice, and then sends an email or a call to the called party. A short text message is notified on the LCD screen of the phone. (C30)

When the called party enters his / her phone number (C31), the incoming call is automatically connected to the second UMS server 100b, and (C32) the called party can successfully listen to the voice message provided by the second UMS server 100b. C33)

In this way, the sender and the receiver communicate through a plurality of UMS servers without managing the UMS number, and can use the unified messaging service provided by the UMS server.

Unified messaging service is available via fax and e-mail in addition to telephone, but since this is similar to the case described above, a separate detailed description will be omitted.

Although the method according to the present invention has been described above, this is merely an example, and various changes and modifications may be made without departing from the spirit of the present invention, all of which fall within the scope of the present invention as described in the appended claims.

As described above, in the present invention, since a plurality of UMS servers are connected through an IP network, even if the sender and the called party are members of UMS servers belonging to different countries, the present invention can be provided with international communication by paying a low IP network fee.

On the other hand, the present invention provides a Unified Messaging service that is automatically connected to the incoming call through a plurality of UMS server network system, the user does not manage a separate UMS number, using the same number that was previously used by the Unified Messaging service There is an advantage of being provided.

Existing companies that provide automatic call forwarding service use a public telephone network to transmit data, so that a communication fee is charged for each distance, and a user needs to pay an expensive fee when using international communication. Since the UMS server connected through the network provides the self-routing service by itself, there is an advantage that the user receives the auto-routing service through the cheap IP network regardless of the distance.
