It may further include. In addition, it is natural that data related to a service, such as subscription information of a service subscriber and a service usage history file, may be stored in the database 440.

First, the call forwarding information according to the present invention will be described with reference to FIG. 3A. 3A, a call forwarding information table 450 according to an embodiment of the call forwarding information is shown.

Early communication services could simply be limited to voice calling services. However, there are various communication services currently provided due to the popularization of the Internet, the development of mobile technology, and the provision of various additional services. Moreover, wired and wireless integration tends to integrate wired and wireless services such as mobile communication. The present invention enables the call forwarding between the various communication services, thereby providing an integrated call forwarding service regardless of the type of wired / wireless or communication service. For example, in the case of a mobile terminal such as a cellular phone, when the called terminal 100-2 is in a call or performing the wireless Internet, the incoming call is not possible, so that the user of the calling terminal 100-1 can terminate the call. There is an inconvenience to wait until. However, when the call transfer is performed as in the present invention, the call connection terminal 100-2 may be connected regardless of the termination of the communication service. For example, when the called terminal 100-2 is accessing the wireless Internet and performing a chat (second communication service), the voice call service (the second terminal) from the calling terminal 100-1 to the called terminal 100-2 is performed. Assume a case where 1 communication service) is requested. In this case, the call forwarding service providing server 400 according to the present invention converts the voice call service request of the calling terminal 100-1 into a mobile Internet service request, and the site to which the called terminal 100-2 is connected. It can be connected to be connected to the destination terminal 100-2 to chat with.

As described above, when the incoming information described in the call forward information table 450 connects the calling terminal 100-1 to the called terminal 100-2, a communication service corresponding to the called terminal 100-2. Refers to information about. That is, the call forwarding information according to the present invention may be defined as a type of communication service allowing call forwarding in the called terminal 100-2, information necessary for switching the call, and the like.

Referring to FIG. 3A, only call forwarding information for a voice call, an email, a messenger, or a chat is illustrated. However, the call forwarding information is not limited to the illustrated portion, and may be variously designated according to a communication service that can be provided. Of course, it can be configured to simply include information on the terminal identifier. In addition, according to the present invention has been described on the basis of the case of managing the call forwarding information in the database in advance, but in response to the communication service request signal of the calling terminal (100-1) in real time to switch the incoming call from the incoming communication network (300-2) Naturally, it can be configured to extract the call forwarding information.

3B is a state information table including state information according to a preferred embodiment of the present invention.

Here, the state information described in the state information table 460 refers to a connection state of the called terminal 100-2 or information of a communication network to which the called terminal 100-2 is connected. With reference to the status information, not only can the incoming terminal 100-2 connect the incoming call to the terminal in the form of a callable communication service, but also the preset communication service even when the called terminal 100-2 is in the callable state. The incoming call of the called terminal 100-2 can be connected. Here, although only a voice call service, an internet service, and a text service are illustrated as the types of the call service, it is natural that other communication services may be included. The state information includes a call state, a messenger connection state, a text message service, an e-mail transmission state, a power off state, and the like. In this case, the status information may be configured to include information of a specific Internet address to which the called terminal 100-2 is connected, as well as a case where the Internet service is not in use. Hereinafter, referring to FIG. When the terminal 100-2 is performing a voice call service, state information including service information capable of call forwarding to the called terminal 100-2 is generated. Here, it is assumed that the destination terminal 100-2 is subscribed to a three-way call service that can make three or more voice calls. The state information may be a call forwarding such as a three-way call service, a recording service, a mail transmission, a message transmission, and the like that can be forwarded. Here, the user of the calling terminal (100-1) is configured to switch the incoming call to a desired communication service method of a plurality of communication services, or to switch the incoming call to a predetermined communication service by operating a button corresponding to the call forwarding communication service do.

In addition, in the case of the existing missed recording service, after the preset time (about 40 seconds to 60 seconds) has elapsed in the called terminal 100-2, the recording service is provided, while the call forwarding service according to the present invention is timed. Regardless of whether you are trying to make a voice call, you can receive a recording service with a simple button operation. Of course, during the voice call service request, it is natural that the call can be switched to a message transmission service or a mail service instead of a recording service.

According to the present invention, the communication network may recognize and switch the incoming call even when the application program is executed inside the terminal without being connected to the communication network. For example, if an incoming service such as a voice call is provided while writing a text message or playing a game on a terminal, a program being executed is forcibly terminated.

Accordingly, when a predetermined application program is executed, such as the application program, status information indicating execution of the application program is transmitted to the communication network through the base station, and when execution ends, status information indicating completion of execution is transmitted to the communication network through the base station. It is composed. Thus, while such an application program is running, the call forwarding information may be set so that the call is transferred to other call means such as a recording service.

In the above case, when a voice call is attempted from the calling terminal 100-1 to the called terminal 100-2, the called terminal 100-2 is inputting a text message. Do you want to go to the mail service? The status information guide message may be provided to the calling terminal 100-1, and the calling terminal 100-1 transfers the desired contents to the called terminal 100-2 by switching the incoming call to the mail service through a button operation. Can be.

Status Information Provision Procedure

4A is a flowchart illustrating a procedure for providing status information of a called terminal according to a preferred embodiment of the present invention. 4B and 4C are diagrams illustrating a state information extraction method according to a preferred embodiment of the present invention. The state information of the called terminal 100-2 according to the present invention can be recognized as shown in Table 1 below. It can be divided into impossible state information. Here, the contents of the recognizable-state information and the non-recognizable state information may be changed according to the configuration of the system. For example, according to the existing method, it is impossible to recognize a program executed in the terminal, but according to the present invention, it may be configured to recognize the running program. The following classification is based on the current operation of the communication service.

Type of status information Contents Recognizable-Status Information Power Off, Opt Out, No Page, Internet, Texting, Games Unrecognized-Status Information Busy, No Answer

Here, the recognizable state information refers to state information that can be recognized by the terminating communication network 300-2 without attempting to connect from the terminating communication network 300-2 to the terminating terminal 100-2. The state information refers to state information that can be recognized only by attempting to connect from the terminating communication network 300-2 to the terminating terminal 100-2.

Hereinafter, a procedure of providing state information of the called terminal 100-2 will be described in detail with reference to FIG. 4A.

First, in step S410, the procedure for providing state information varies depending on whether the state information is previously recognizable information, and whether or not the state information can be recognized according to the present invention may vary depending on the type of service and the configuration of the system. According to the conventional method, when the incoming call is received during the execution of a game stored in the terminal during message input, the game in progress is terminated or the input text message is deleted, but according to the present invention, the terminal Among the operations performed internally, the execution of a preset program can be configured to be recognized.

In the case of recognizable state information, the state information can be extracted without attempting to connect with the called terminal 100-2. That is, in step S420, the call forwarding service providing server 400 receives the state information from the incoming communication network 300-2, extracts the state information received in step S430, and transmits the state information to the calling terminal 100 in step S440. -1) can be provided. On the other hand, in the case of unrecognized state information, in step S425, the terminating communication network 300-2 attempts to connect with the terminating terminal 100-2, and if such connection is not performed, recognizes as state information such as absent. . In operation S435, the call forwarding service providing server 400 may extract state information by performing the procedure performed in steps S430 and S440. Of course, while attempting to connect with the called terminal 100-2, recognizable status information is continuously provided, and unrecognizable status information is recognized, and the status information can be added and provided. Here, the method of providing the status information may of course provide the current status information on the display of the terminal, instead of the ring tone.

In step S440, the call forwarding service providing server 400 provides the extracted state information to the calling terminal 100-1, and may be configured to switch the call in a predetermined manner in step S450. FIGS. 4B and 4C are shown. A flowchart illustrating a method of extracting state information according to a preferred embodiment of the present invention.

The extraction method of the state information according to the present invention includes a first method of receiving and storing state information of the called terminal 100-2 in advance and extracting it from the stored state information when a communication service request is made to the called terminal 100-2. FIG. 4B and the second method of receiving and extracting the state information provided by the terminating communication network 300-2 after requesting the status information to the terminating communication network 300-2 in real time when the communication service is requested (FIG. 4C). First, referring to FIG. 4B, the first method will be described. In step S461, the destination communication network 300-2 generates a state information generation signal for generating state information from the destination terminal 100-2. In this case, the state information generation signal refers to information related to the state information among the signals transmitted to perform the communication service in the destination terminal (100-2). For example, when the called terminal 100-2 transmits a voice communication service request signal to perform a voice call with another terminal, the voice communication service request signal may be a state information generation signal. In step S463, the destination communication network 300-2 generates state information by using the state information generation signal, and transmits the state information generated in step S465 to the call forwarding service providing server 400. When the call forwarding service providing server stores the received state information in step S467 and receives a communication service request signal from the calling terminal 100-1, the state corresponding to the called terminal 100-2 in step S469. Configured to extract information.

4C, the state information is generated in the same manner as in the above-described steps S461 and S463 in steps S471 and 473. FIG. When the terminating communication network 300-2 receives the state information request signal from the call forwarding service providing server 400 in step S475, the state information corresponding to the terminating terminal 100-2 is extracted in step S477. The state information extracted in S479 is transmitted to the call forwarding service providing server 400. The call forwarding service providing server 400 may obtain state information of the called terminal 100-2 by receiving state information from the incoming communication network 300-2 in real time.

According to the first method, the state information extraction time is reduced, but there is a disadvantage in that the state information of the called terminal 100-2 must be stored and managed in the call forwarding service. In addition, when the second method is used, the burden of processing the call forwarding service providing server 400 is reduced. However, since the procedure of inquiring the call forwarding communication network 300-2 must be performed each time the call forwarding is performed, it takes more time. have.
