Abstract

PURPOSE: A call processing service providing method in a telephone network and instant message network-combined environment is provided to allow a caller to transfer a message to a callee by using an instant message network if the line of the callee is busy. CONSTITUTION: When a subscriber 'A' inputs a phone number of a subscriber 'B', an origination exchange collects routing information of a destination terminal and requests a call connection to a destination exchange(S101). If the destination terminal is in an hook-off state(S102), the destination exchange transmits a CID(Caller Identifier) to a message relay server and the message relay server determines whether a messenger client of the destination subscriber 'B' is in an on-line state(S104). If the messenger client of the destination subscriber 'B' is in an on-line state, the message relay server reports on the messenger available state of the destination subscriber 'B' and the destination exchange sends an announcement according to message usage to the origination terminal(S105). If the origination subscriber 'A' inputs a digit 2(S106), the message relay server outputs a 'message creation window' to a message client of the origination subscriber 'A', and when the origination subscriber 'A' inputs a text format of message and transmits it, the message relay server transfers the message to the message client of the destination subscriber 'B'(S109).

Description

Method for processing calls under coupled environment of telephone network and instant messaging service network

The present invention relates to a method for providing a call processing service in an environment in which a telephone exchange network and an instant message network are combined. More particularly, when a call connection is not possible in a telephone exchange network due to a caller's incapacity, a caller's message is sent to a recipient's messenger client. The present invention relates to a call processing service providing method in an environment in which a telephone exchange network and an instant message network are combined to enable delivery.

Typically, voice calls processed by PBXs, public telephone networks (PSTNs), and Voice over Internet Protocol (VoIP) are call channels between the calling party and the called party when the subscriber corresponding to the called party number requested by the calling party is busy. It can't be formed, and can't make the call successful. However, if the called party selects a function such as "call waiting" provided as an additional service, it is possible to recognize the state called by the calling party, but in this case, the call with the currently busy party is temporarily It is inconvenient to answer the call of the calling subscriber in a suspended state.

On the other hand, as the penetration rate of the Internet or intranet is rapidly increasing, a messenger client (for example, a PC) capable of Internet or intranet supports a real-time message transmission such as AOL Instant Messenger (AOL) or MSN Messenger of Microsoft. When installed, multiple messenger clients can be notified by notifying the subscriber when a friend who is registered in the list that he made in advance has logged on to the network and receiving a message sent to any friend. Enables information exchange in real time.

This technique is done by a message relay server configured on the Internet or intranet. The message relay server grasps the status of the logged-in messenger client and exchanges information between the clients. The communication network formed between the message relay server and the messenger client is called an instant message network.

The present invention is to solve the problem that the calling subscriber was unable to deliver a message to the called party when the called subscriber is busy in the conventional telephone network, the calling subscriber to the called subscriber using the instant message network when the called subscriber is busy in the telephone network An object of the present invention is to provide a method for providing a call processing service in an environment in which a telephone exchange network and an instant message network are configured to deliver a service.

Method for providing a call processing service in an environment in which a telephone exchange network and an instant message network are combined according to an embodiment of the present invention for realizing the above object,

A method for providing a call processing service in an environment where a telephone exchange network is connected to a message broker server of an instant message network,

A first process of determining whether a messenger client registered to the called subscriber is online connected to the message relay server when the called subscriber is busy while the calling subscriber of the telephone switching network calls the called subscriber of the telephone switching network; ;

If the messenger client of the called subscriber is in an online state, transmitting a guide broadcast according to the use of a messenger to the calling subscriber in the public network; And

When the use of the messenger from the calling subscriber is requested according to the announcement, a third process of delivering a message from the calling subscriber to the messenger client of the called subscriber is characterized in that it is made.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail.

According to an embodiment of the present invention, a system for providing a call processing service providing method in an environment in which a telephone exchange network and an instant message network are combined, as illustrated in FIG. 1, includes terminals 101 and 201 connected through a telephone exchange network 500. And a messenger client (102, 202) using an instant messaging service by the message mediation server (400).

In addition, subscriber A and subscriber B have messenger clients 102 and 202 and terminals 101 and 201 mounted with the same messenger program, respectively.

Next, an operation of the call processing service providing system in an environment in which the telephone exchange network and the instant message network are combined according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 2.

In the above configuration, when subscriber A inputs subscriber B's landline telephone number (042-870-8000) (called number) by using terminal 101 (calling terminal), telephone exchange network in which calling terminal 101 is accommodated. The calling exchange of 500 collects the routing information of the called terminal (subscriber B terminal) by translating the called number, and requests a call connection to the called exchange of the telephone exchange network 500 that accepts the called terminal. (S101).

As a result of the determination at the destination exchange, if the destination terminal is in the hook-on state, that is, the destination terminal is not busy (NO in S102), a ring signal is transmitted to the destination terminal to call the destination terminal. When the called terminal is in a hook-off state, the calling terminal and the call path of the called terminal period are connected to enable a telephone call between both terminals (S103). Step S103 corresponds to a procedure of a general fixed line telephone call processing service performed by the telephone exchange network 500.

However, unlike the case described above, when the called terminal determines that the called terminal is in a hook-off state, that is, the called terminal is busy (YES in S102), the message intermediary server 400 includes caller / called number information. The CID (Caller Identifier) is transmitted, and the message broker server 400 receives the subscriber B currently on the basis of the calling party number, the called party number, the log status information, etc. stored in the subscriber DB 300, It is determined whether the messenger client 202 is online (S104).

As a result of the determination in step S104, if the messenger client 202 of the called subscriber B is not online (NO in S104), the telephone exchange network 500 sends a busy signal to the terminal 101 of the calling subscriber A. After that (S110), the flow advances to step S104 to check repeatedly whether the called party B is busy.

On the other hand, if it is determined in step S104 that the messenger client 202 of the called subscriber B is online (YES in S104), the message mediation server 400 sends a messenger available state of the called subscriber to the telephone exchange network 500. The call exchange network 500 transmits a guide broadcast according to the use of a messenger to the calling terminal 101 through a voice guidance system (not shown).

At this time, the announcement broadcasted is, for example, "Please select-1: response request by phone, 2: leave a message by messenger".

Then, when a predetermined digit is input from the calling terminal 101, the destination exchange of the telephone exchange network 500 transmits the digit information to the message relay server 400.

Here, if the digit input from the calling terminal 101 is "1", the message relay server 400 generates a call request window as shown in FIG. 3 and outputs it to the messenger client 202 of the called subscriber B.

As shown in FIG. 3, the call request window displays a request time, a request partner (caller), and a contact information (email address and phone number, etc.) from the callee, and corresponds to a response according to the call request. Configure tags such as input / call in Ignore / Call list. The contact information for the requesting partner utilizes information stored in the subscriber DB 300 of the message mediation server 400.

When the called party B selects "ignore" in the call request window, the call reservation is rejected from the calling party B, and when the "call list" is selected in the call request window, the message is sent. It is stored in the reserved area so that the called party can confirm this later, and when "call" is selected in the call request window, a call is established between the terminal of the calling party A and the terminal of the called party B. .

On the other hand, the call request list registered by the call request window can be configured as shown in Figure 4, when the subscriber activates the call request list or clicks a phone number on the call request window, the message relay The server 400 interworks with the telephone exchange network 500 so that the terminal 201 of the subscriber B and the terminal 101 of the subscriber A are called to enable a telephone call, and the subscriber activates the call request list. When the email address is clicked on the call request window, the email written by the subscriber B is transmitted to the corresponding email address in association with a mail server (not shown).

On the other hand, when it is determined in step S106 that the input of the digit "2" from the originating subscriber A is determined, the message relay server 400 uses the information of the originating subscriber A stored in the subscriber DB 300. By outputting a "send message creation window" as shown in Figure 5 to the messenger client 102 of the calling subscriber (A), and when the calling subscriber (A) enters a message to be sent to the called subscriber (B) in text form, The message mediation server 400 transmits the message transmitted by the calling subscriber A to the messenger client 202 of the called subscriber B (S109).

In the present invention, when the calling subscriber attempts to make a phone call to the called subscriber, when the other party is busy, the calling subscriber may transfer a message or request a call using the instant messaging service.

According to the present invention as described above, it is possible to improve the success rate for the call attempted by the calling subscriber, and even if the called subscriber does not answer, the calling subscriber can deliver the message to the called subscriber. This has the effect of improving satisfaction.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
