Dynamic call transfer control device and method in internet communication network

The present invention relates to a dynamic call transfer control apparatus and method thereof in an internet communication network, and more particularly, to create a user profile for a specific user in an internet communication network and to prioritize network addresses of terminals directly used by the user. When a call setup request is generated while the call forwarding rule is freely responded, a call processing agent who substitutes the call forwarding request forwards the call to the user's preferred terminal according to the call forwarding rules and priority specified in the user profile. A call forwarding control device in an Internet communication network in which a communication service is possible only by an identifier of a receiving user even when the transmitting side does not know the address of a terminal used by the receiving user or the receiving user moves. It is about a method.

Call transfer control method in the existing wired telephone network has an intelligent network component in a telephone exchange or a private branch exchange (PABX), and when a call transfer request is received to a specific telephone number, it is transferred to another telephone number (Call transfer). Could provide).

However, in this method, the sending user specifies the telephone number used by the receiving user, that is, the communication is performed using the network address of the point where the terminal is connected to the network. The method was not available.

In addition, in the Internet communication network environment where intelligent terminals such as computers are mainstream, it is expected that customized services suitable for the characteristics of the terminal and the characteristics of the application software installed in the terminal may be provided by the user. There is a need for a call control method that can be serviced.

In addition, in the general call forwarding control method of a general telephone network, only one other phone number corresponding to one phone number corresponds to a lack of flexibility in call forwarding control, and dynamically according to a priority set by a user or a specific call forwarding rule universally available. It was impossible to convey.

Therefore, even if an individual user is recognized in the Internet communication network and the user identifier is used as a medium for call forwarding, the user can transfer the call to the terminal currently in use or to the terminal designated by a specific rule even if the user ID is called only. The user can directly specify a specific priority or call forwarding rule in his or her user profile to dynamically control a call transmitted to a specific receiver so that the communication service can be provided as intended by the receiver.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the call processing agent in the communication network receives the identifier and distinguishes and receives the receiving user when the transmitting user merely calls the receiving user's ID. The terminal can locate the terminal selected according to the situation according to the rules or priorities specified by the user and forward the call to the user. The terminal can be used by the receiving user to suit his purpose. The purpose of the present invention is to provide a dynamic call forwarding control device and method in an internet communication network that allows a user to receive a call to an intended terminal by assigning or prioritizing a rule capable of forwarding a call to the terminal for each time.

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

1 is a block diagram of a dynamic call transfer control device in an Internet communication network according to the present invention, and the configuration shown in the figure is a terminal for a communication service installed in a distributed computer environment required for an embodiment of the present invention. Applications (TP11, TP12, TP13, TP14), profile editors 101, 102, 103, 104 installed in terminals 11, 12, 13, and 14 for editing user profiles in the network, user profiles (UP (A), UP (B) ), The user profile manager 401, the call processing agent 301, and the physical configuration between the network devices (switches or routers) 21 and 22.

In this case, the user profile manager 401 provides a function of allowing the user to edit a user profile and a user profile specified for each user identifier and user identifier determined at the time of subscription.

The profile editors 101, 102, 103, and 104 are connected to the user profile manager 401 in the network to be installed in the terminal to edit their user profile.

In addition, the call processing agent 301 may select a network address of a specific terminal by analyzing call forwarding rules and priorities specified in a user profile, and transmit a call to the selected terminal or request a call transfer from a transmitting terminal. Will receive.

In addition, the terminal applications (TP11, TP12, TP13, TP14) that can exchange a call with the call processing agent 301 are implemented as a software component on a computer hardware device, and each terminal application (TP11, TP12, TP13, By enabling communication between the remote processors between the TP14) and the call processing agent 301, it is possible to control the call transfer to the terminal selected by the user.

That is, in FIG. 1, the terminals 12, 13, and 14 used by the sender terminal 11 and the user B are implemented / installed with terminal applications TP11, TP12, and TP13, respectively, to the call processing agent computer 31. It is possible to exchange information for call forwarding with the installed call processing agent 301 and a remote processor. Here, a plurality of call processing delegates used by a specific terminal application may exist in the network, and the user may receive a call processing delegate capable of using his own terminal application at the time of joining or when the terminal application is first executed on the terminal. Can be assigned using a specific protocol for process delegate selection.

As shown in Fig. 2, information for call forwarding is used in the sender's user identifier, the sender's network address, the call processing agent computer's network address, the receiver's user identifier, and the call processing process. The network address of the receiving terminal to be received, the call setup code that can know whether the receiver accepts the call through the receiving terminal application and the data for the additional service can be added through the present invention, the sending terminal It is exchanged between the terminal application and the call processing delegate of the terminal application and between the call processing delegate and the terminal applications of the receiving terminal which can be the receiving target.

When using such a format of call forwarding information, as shown in FIG. 1, when the transmitting user A finds the user B and requests a call forwarding, the call processing agent 301 transmits the user A to the user B from the transmitting terminal application TP11. The user profile UP (B) corresponding to the receiving user B is searched by receiving a call processing request delivered to the user B, and the priority and call forwarding rules of the user B recorded in the current user profile UP (B) are found. By doing so, it is possible to find out the address of the terminal to be finally delivered.

Referring to the user profile shown in FIG. 3, the profile is configured to give a priority and a rule to a network address of a specific user and a terminal usable by the user. The user profile of the user is added or changed the call forwarding rules and priorities in the user profile through the user profile manager 401 existing in the network using the user profile editors 101, 102, 103, 104 installed in each terminal as shown in FIG. This is possible through the web server and web browser based on the HTTP (HyperText Transfer Protocol) common on the Internet.

The profile of user A shown in FIG. 3 means to always forward a call transmitted to the terminal 11 to the terminal 11, that is, the terminal whose network address is terminal 11, and the profile of user B is determined by rule A every day. From 9 am to 6 pm, forwarding calls are sent to terminal 12, or calls forwarded from user A by rule B to terminal 13 at any time, or by rule C and rule A by rule C. If a call forwarding request that does not apply to B occurs, it means to send to the terminal 14. By priority, rules A and B have the same priority, meaning that rules A and B must be applied before rule C. Have A user-specified call forwarding rule is a set of all logical conditions that can be implemented by software technology. In addition to the above examples, a call forwarding rule can be newly defined or added for user convenience.

Figure 4 is a block diagram showing the configuration of the terminal application and call processing agent configured in the dynamic call transfer control apparatus in the Internet communication network shown in Figure 1, by using the call transfer information format and the user profile An internal configuration block diagram of a terminal application and a call processing agent capable of performing complete call forwarding control is shown.

In FIG. 4, the terminal application TP11 includes a user information unit TP11a capable of recording that a specific user A is a user, and a user command input / output unit TP11b capable of inputting / outputting information such as call setup request or whether the user has entered or not. And the call processing unit 301b inside the call processing delegate 301 and the call transfer information shown in FIG. 2 to notify the user command input / output unit TP11b, and receive a user's response to call the call processing delegate 301 again. Call transfer information exchange unit (TP11c) for delivering the results to the processing unit (301b), and other terminal applications (TP12, TP13, TP14) is configured in the same form as the terminal application (TP11).

In addition, the call processing agent 301 is a call processing unit 301b capable of exchanging calls with call transfer information exchange units TP11c, TP12c, TP13c, and TP14c of each terminal application (TP11, TP12, TP13, TP14); The user profile analysis unit 301a, which analyzes the call transfer information received from the call processing unit 301b and analyzes the call transfer rules and priorities recorded in the user profile UP (B) and selects the network address of the terminal according to the situation. It consists of.

5 is a diagram illustrating a call transfer control flow executed using a call processing agent and a user profile by a dynamic call transfer control apparatus in an Internet communication network according to the present invention.

Referring to the drawing, assuming that a situation where the transmitting user A calls the user B from the terminal application TP11 on the terminal 11 side at 11 am, the transmitting terminal of FIG. 1 in step S1 of FIG. When user A requests call setup from user B using terminal application TP11 in (Terminal 11), the user command input / output unit TP11b in terminal application TP11 receives the request and the call transfer information exchange unit ( The command is sent to TP11c, and the call transfer information exchange unit TP11c sends call transfer information to the call processing unit 301b of the call processing agent 301. At this time, the transmitted call forwarding information corresponds to step S1 of FIG. 2 and records who is the sending user, which terminal requests call setup, and what is the identifier of the receiving user.

In step S2 of FIG. 5, the call processing unit 301b of the call processing agent 301 that has received the call transfer information in step S1 sends the information to the call processing analyzer 301a, so that the receiving terminal user B prefers which terminal. You will be asked to choose whether or not to do so (ie network address request).

The call processing interpreter 301a of the call processing agent 301 received the request retrieves the user profile UP (B) shown in FIG. 3 and interprets the rules and priorities. In the rule shown, since rule A and rule B can be applied at the same time, the call processor 301a first applies rule A to transfer the call to the terminal having the terminal 12 (that is, Terminal 12) as the network address, and the call transmission fails. In this case, the rule B may be applied to transfer a call to a terminal using the terminal 13 as a network address (step S3 of FIG. 5).

When the analysis is completed in step S3, the call processing interpreter 301a preferentially transmits the call to the terminal 12 having the network address (Terminal 12) to the call processing unit 301b, and fails if the terminal (Terminal 13) is the network address. A response is transmitted to the terminal 13 to transmit the call (step S4 of FIG. 5).

The call processing unit 301b sends the call forwarding information illustrated in step ST5 of FIG. 2 to the terminal 12 having the selected terminal address terminal 12 (step S5 of FIG. 5).

The call transfer information transmission unit TP12c of the terminal application TP12, which has received a call setup request from the call processing unit 301b, notifies the user of the fact through the user command input / output unit TP12c and waits for the user's acceptance or not. In this state, it is assumed that the call setup request is rejected because the user B rejects the call setup or the terminal 12 is not in use (step S6 of FIG. 5). The call transfer information transmitting unit TP12c of the terminal application TP12 specifies a call setup code as 'X', and calls the call processing unit 301b of the call processing agent 301 again. (Step S7 of FIG. 5).

The call processing unit 301b of the call processing agent 301 confirms whether or not the call is set. If the call is accepted in the state, the call processing unit 301b proceeds to step 14 of FIG. 5, but if not, proceeds to step S9 of FIG. 5. It proceeds (step S8 of FIG. 5). In this case, since it is not accepted, it is checked whether it is possible to send a call to another terminal. If there is no terminal that can send a call at this stage, the call transfer information exchange unit (TP12c) of the transmitting terminal application (TP11). It informs the call that a call cannot be established and cancels the call (step S9).

Since the call setup is not accepted and the call can be sent to another terminal, the call processing unit 301b is illustrated in step S10 of FIG. 2 as the call transfer information transmitting unit TP13c of the terminal application TP13 having the next priority. Call transfer information is sent (step S10 of FIG. 5).

The call transfer information transmission unit TP13c of the terminal application TP13, which has received the call setup request from the call processing unit 301b, informs the user of the fact through the user command input / output unit TP13b, where user B Assume that the call can be accepted in that state (step S11 of FIG. 5).

Informing the call transfer information transmitting unit TP13b of the user command input / output unit TP13b that the acceptance is possible, the call transfer information shown in step S12 of FIG. 2 is sent to the call processing unit 301b of the call processing agent 301. (Step S12 of FIG. 5).

The call processing unit 301b confirms whether call setting is accepted (step S13 of Fig. 5). The call processing unit 301b sends the call transfer information illustrated in step S14 of FIG. 2 to the call transfer information exchange unit TP11c of the terminal application TP11 that was the original transmission side (step S14 of FIG. 5).

The sender call forwarding information exchange unit TP11c realizes that a call can be established between terminals having a network address (Terminal 13), and runs or informs an information exchange software application installed in the terminal, for example, an application such as an Internet telephone. A logical connection between the terminal 11 and the terminal 13 illustrated in FIG. 1 can be established. In this case, the information exchange software application can transmit the Internet packet using the network address (Terminal 13) of the receiving terminal illustrated in step S14 of FIG. 2 (step S15 of FIG. 5).

Therefore, if such a step is passed, the sending terminal uses the information recorded in the call processing agent and the user profile with only the identifier of the user B without knowing the network address information of the terminal used by the receiving user B. The network address (terminal 13) of the user can be determined, and the user's B transfer rule and priority can be controlled by the user profile manager 401 in the user profile UP (B). Since various call delivery methods and user preferences can be introduced, it is possible to provide a dynamic call delivery control method that can use Internet applications reflecting user-specific characteristics.

As described above, according to the present invention, a user profile for managing a user profile for each unique user identifier and a user profile in an Internet communication network, in which an intelligent wired terminal such as a computer is mainstream, can be implemented by software. Within the limits that can be implemented in software, preferences can be edited in a variety of ways, thereby providing a way for calls to be dynamically distributed or forwarded at the user's will.

In addition, even when the network address of the terminal used by the user is unknown, the user profile corresponding to the user identifier can be searched and the rules and priorities recorded in the user profile can be analyzed when the user wants to use the communication service using only the user identifier. The call processing agent is implemented as a software component inside the network and the terminal application is implemented as software in the terminal to be used by the user so that call transfer information can be exchanged between them. Regardless of whether or not, the call can be transmitted using only the user ID of the receiving party and the corresponding user profile, and the connection between the transmitting terminal and the user's preferred terminal can be established based on the established call.

In addition, call forwarding for intelligent network services such as call forwarding, call waiting, call pause, and completion of calls to busy subscribers (CCBS) that can be used in the basic landline network without restricting the definition of rules recorded in the user profile. By allowing users to set rules by themselves, various intelligent network services can be complexly realized without implementing special intelligent network components on the Internet.
