Description

{Method for call forwarding}

The present invention relates to a mobile communication service, and more particularly, to a call forwarding method.

Mobile communication terminals are becoming essential communication means in modern life. A user may accidentally leave the mobile communication terminal at a place such as a home or office, or the power of the mobile communication terminal may be turned off due to insufficient battery power. In this case, it is impossible to receive a call or data using the communication terminal. If another person calls a person who does not have the mobile communication terminal and the call is not connected, the calling user continuously tries to make a call connection until he / she hears the guidance message. In addition, if the call is not connected, the calling user will try to connect again after a short while, thereby increasing communication traffic. In order to solve these problems, an incoming telephone number changing service has been introduced.

The called telephone number change service is a service for registering a telephone number of a wired telephone or a mobile communication terminal capable of making a call in a call forwarding service server when a user who has subscribed to the incoming telephone number changing service can not carry the mobile communication terminal, The server refers to a service that connects a call to a telephone number that is disabled to a registered forwarding telephone number. Examples of the services that are targeted for call forwarding services include voice and wireless communication services such as voice calls, short messages, multimedia messages, instant messengers, and voice mail.

1 is a block diagram schematically showing the principle of changing an incoming telephone number. The terminal B 120 is a terminal registered in the called telephone number change service, and is a terminal that the user can not carry. The user who can not carry the terminal B 120 can receive the telephone number of the terminal C 130 through the network communication network 140 to the terminal C 130 or any other communication terminal, . Accordingly, when a call attempt is made from the terminal A 110 to the terminal B 120, the network communication network 140 makes a call attempt to the terminal C 130 without making a call to the terminal B 120. Here, the network communication network 140 is a concept including a mobile communication network including a radio base station and a telephone exchange station, and a public switched telephone network.

On the other hand, incoming phone number change service is generally provided in two ways. One is a conditional termination number change service. When a call attempt from the terminal A 110 to the terminal B 120 occurs, the terminal B 120 rings for a certain period of time and then a response is received from the terminal B 120 The call is made to the terminal C 130 registered with the incoming telephone number.

Of course, this case will be possible when the power of the terminal B 120 is on. The other is an unconditional subscriber telephone number change service. When a call attempt from the terminal A 110 to the terminal B 120 occurs, a call is made to the terminal C 130 registered in the called telephone number. Of course, due to the nature of the incoming phone number change service, unconditional incoming phone number change service is mainly used.

 When setting up the call forwarding service according to the existing call forwarding service, the call forwarding service server verifies only the validity of the service subscription / authority of the call forwarding setting subscriber and the validity of the subscription of the call forwarding phone number to which the incoming call is to be forwarded. Accordingly, the call forwarding service server can not confirm the actual incoming telephone number and the service availability state of the final call forwarding communication terminal when the call forwarding service is set by the user, and only the communication terminal having the actual conversion number and the terminal Since the service state is recognized, the following problems may occur, which is inconvenient to the user.

First, when the redirected telephone number is redirected, the user recognizes that the redirected number is redirected to the redirecting number set by the user. Therefore, it may happen that the actual call forwarding number may not be recognized. For example, suppose that the terminal B is in the state of being redirected to the terminal C and the user of the terminal A who does not know it is about to call forward to the terminal B. At this time, the user of the terminal A does not recognize that the terminal B has already performed the call forwarding to another communication terminal. Therefore, the user of the terminal A recognizes that the terminal B phone number is forwarded. Thus, when a redial occurs, it is necessary to notify the user who is trying to set up the redirect forwarding number information.

Second, if the mobile communication terminal of the forwarding telephone number fails to receive the communication service due to low battery or power off, the call forwarding can not be performed, but the user who attempts to establish the forwarding call can not recognize the call forwarding.

An object of the present invention is to provide a call forwarding method capable of preventing an error due to redirection.

It is another object of the present invention to provide a call forwarding method capable of preventing an error that may occur when setting up a call forwarding service of a communication service.

It is another object of the present invention to provide a call forwarding method capable of indicating communication state information of a forwarding telephone number.

It is yet another object of the present invention to provide a call forwarding method capable of indicating a substantial service availability of a substantial call forwarding telephone number.

According to another aspect of the present invention, there is provided a call forwarding method comprising: receiving a call forwarding service request signal from a call forwarding service provider; Collecting information on whether the call forwarding service server redirects the call forwarding service request number; If the call forwarding service request number is the redirected number, returning to the step of determining whether or not the call forwarding service is available using the redirected number of the call forwarding service server, performing the corresponding operation; And if the call forwarding service request number is not the redirected number, the call forwarding service server transmits a message including the call forwarding number information finally switched to the call forwarding setting server according to the service setting .

Another aspect of the call forwarding method according to the present invention is that when the call forwarding service request number is another communication network number, the call forwarding service server further includes a step of transmitting a signal for requesting information on re- will be.

Another feature of the call forwarding method according to the present invention is that the call forwarding service server provides information according to any one of announcement, short message service (SMS) and conversion number indication to the call forwarding setter.

Another aspect of the call forwarding method according to the present invention is that the call forwarding service server provides communication terminal service status information of the call forwarding number to the call forwarding setter.

Another aspect of the call forwarding method according to the present invention is that the call forwarding service server is configured to perform a call forwarding service such as power-off, international roaming, do-not-disturb, incoming call screening, And provides the communication terminal service status information including any one of the cycling states.

Another aspect of the call forwarding method according to the present invention is that the call forwarding service request signal is provided to the call forwarding service server through any one of a mobile communication network, a public switched telephone network (PSTN), and the Internet.

The call forwarding method according to the present invention has the following effects.

First, the call forwarding setter can be provided with information on the actual call forwarding number.

Second, the communication terminal service status information of the call forwarding number can be provided to the call forwarding setter.

FIG. 1 is a schematic diagram illustrating a general call forwarding service. Referring to FIG.
FIG. 2 is a system configuration diagram for implementing the call forwarding method according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention in the drawings, portions not related to the description are omitted, and like reference numerals are given to similar portions throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise. Also, the terms " part, "" module," " module, "and " block" refer to units that process at least one function or operation, Lt; / RTI >

FIG. 2 is a system configuration diagram for implementing the call forwarding method according to the present invention. As shown, the application of the call forwarding service can be implemented by various methods. The call forwarding application signal using the mobile communication terminal 10 is transmitted to the call forwarding service server 70 via the base station 40. [ The call forwarding service setting signal by the general home telephone 20 is transmitted to the call forwarding service server 70 via the general public telephone network (PSTN) The Internet telephone 30 is connected to the call forwarding service server 70 through the Internet network 60. [ The call forwarding service server 70 is connected to a database storing call forwarding service use information. A home location register (HLR) 82 and a visitor location register (VLR) 81 are connected to the call forwarding service server 70. The call forwarding service server 70 may transmit a communication status information request signal to the third party network server 90 when necessary. The database 91 in which the call forwarding information is stored is connected to the third party network server 90.

The call forwarding service server 70 not only receives the setting signals from the respective communication terminals 10, 20 and 30 but also transmits a call signal for call forwarding and a signal for communication service processing using the same communication path .

3 is a flowchart illustrating a process of a call forwarding method according to the present invention. The call forwarding setter transmits the call forwarding setting signal to the call forwarding service server 70 using the communication terminal of either the mobile communication terminal 10, the home telephone 20 or the Internet telephone 30.

The call forwarding service server 70 uses the database 71 to confirm whether the user of the mobile communication terminal having the forwarding telephone number is the forwarding service subscriber.

If it is not a service subscriber, the call forwarding service server 70 sends a notification signal indicating that the service is disabled to the communication terminal of the user, and the notification signal may be displayed in the form of a voice message or a text message. On the other hand, in the case of a normal service subscriber, the call forwarding service server 70 checks whether the forwarding telephone number is the telephone number of another mobile communication company.

 On the other hand, in the case of a telephone number of another mobile communication company, the call forwarding service server 70 transmits a signal for requesting the status information of the forwarding telephone number to the management server of another mobile communication company. The management server 90 of the other mobile communication company confirms whether or not the service is subscribed through the database 91, confirms the communication status information of the current forwarding telephone number, and transmits a status information response signal based on the result to the call forwarding service To the server (70).

If the forwarding telephone number uses the private communication service, it confirms whether or not the call is redialed. That is, it is checked whether the forwarding telephone number requested by the user has already been forwarded. For example, if the user requests to forward a call signal to an "A" number to a "B" number, the call forwarding service server 70 will send an acknowledgment of the current communication state of the "B" , It is checked whether or not the "B" number is set to be forwarded to another number, that is, whether it is "redialing".

In this way, there may be various cases of the "redialing" For example, the user may have previously forgotten to terminate the call after setting the incoming call to the "B" telephone number to the "C" number. There is a case where the user does not cancel the call setup after performing the international roaming service because of frequent overseas trips and the like.

As described above, in the case of redialing, the call forwarding operation is fed back to the step of requesting the user to set up the redirect. That is, the call forwarding operation may be performed not by searching for status information but by checking whether the user has subscribed to the telephone number for which the first call forwarding has been requested, do. For example, the call forwarding service performs the call forwarding setting process for the target phone number set for call forwarding in the "B" terminal rather than the telephone number "B "

When the state information on the last forwarded telephone number is extracted, the call forwarding service server transmits a response signal including the final forwarding telephone number and the state information of the communication terminal to the setting requesting user. The response signal may be provided in the form of a voice message or a text message. The communication status information may include status information of any one of power-off, international roaming, do-not-disturb, incoming call screening, and call forwarding.

Accordingly, the call forwarding user can know the accurate information on the call forwarding number finally set at the call forwarding setting time.
