The present invention relates to a call forwarding service method, in particular, capable of selectively rejecting a call for a specific call number in a mobile communication system.

Recently, the penetration rate of mobile phones has been increasing rapidly, with the number of mobile subscribers overtaking the number of fixed line subscribers. Using a mobile phone has a lot of conveniences in life, such as sending and receiving text messages or using wireless Internet services. At the same time, however, the mobile phone penetration rate has risen rapidly, and all kinds of advertising information using mobile phones is disturbing, which makes users uncomfortable.

1 is a flowchart illustrating a conventional call restriction service method.

Referring to FIG. 1, a subscriber of a mobile communication system registers an additional service called Password Call Acceptance (PCA) in a home location register (HLR) in order to restrict an incoming call (S101). . Here, the home register register has a database function in the network that manages subscriber information, location information, etc. for providing a service to a mobile terminal at a fixed point in the network.

The exchange 120 checks the called number transmitted from the exchange in the home register register (HLR) 130 when the specific originating subscriber 110 attempts to call origination (S102) (S103). The home register register 130 checks whether the subscriber corresponding to the called number is a registered subscriber of the password call permission service (S104), and if the subscriber is a service registered subscriber, sends a message to the caller 110 to attempt a password verification procedure. In step S105, the switch 120 attempts to confirm the password to the calling subscriber 110, receives the padword, and delivers the password to the home register register 130.

The home register register 130 checks whether the password matches the password registered by the service subscriber (S106), and if it matches, accepts call authentication and notifies the exchange, and the exchange performs an incoming call setup procedure (S107). However, if the password does not match, the caller is restricted (S08).

2 is a flowchart of a case where a password call permission service is successful.

Referring to FIG. 2, when the calling subscriber 110 attempts to make a call, the exchange 110 transmits the information to the home location register 130 including the called party's telephone number in a location request message (S111, S112). If the called party's phone number is a PCA service subscriber, the location register 130 requests the calling subscriber through the exchange (S113, S114, S115). When the calling subscriber enters a password, the home location register 130 checks whether the password matches and then delivers the information indicating that the calling subscriber accepts the call connection to the location request response message (Location Req_ACK) (S116 to S119). The exchange 120 performs a call by performing an incoming call setup procedure of the calling subscriber (S120).

Thus, in order to check whether the calling subscriber knows the password set at the time of service registration in the home location register, it is necessary to know whether the password is known, and if the subscriber does not know the password after this verification procedure, There is no call to the corresponding subscriber to the service registration, it is connected to another incoming call number or to operate a specific announcement broadcast.

As such, in the related art, a subscriber of a mobile communication system registers an additional service called PCA in a home location register to receive only incoming calls by outgoing subscribers who know a password.

However, in the related art, when attempting to restrict a call as a service such as allowing a password call in a mobile communication system, a procedure for confirming whether a password is known to a calling subscriber is necessarily implemented, so that call forwarding is currently performed to a caller. This can be offensive to the caller,

In addition, in the aspect of mobile communication system, since the procedure for checking the corresponding password occupies the radio resource and the line of the exchange for a long time, there is a problem in terms of the efficiency of the system. As the subscriber recognizes that the call has already been attempted and attempts to connect in another way, there is a limit in implementing the fundamental call restriction.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a call forwarding service method that allows a call forwarding procedure for a calling subscriber to perform a call forwarding procedure to another call forwarding number.

Another feature of the present invention is to provide a call forwarding service method for allowing a call forwarding target to be set differently for each caller in a call forwarding list.

Another feature is to provide a call forwarding service method that allows a subscriber to select a call forwarding target.

Call limiting service method according to the present invention for achieving the above object,
A subscriber of the mobile communication system registering an incoming call number and a call forwarding number for each caller in the call restriction list in the home location register to apply for an additional service;
When another subscriber attempts to call the subscriber, the exchange includes: transmitting a location information request message including an incoming telephone number and an outgoing telephone number to a home location register;
The home location register, if the incoming call number included in the location information request message is a selective call restriction service registered subscriber, compares whether a caller's phone number exists in the incoming call restriction list registered by the called subscriber, and compares the incoming call restriction list. If the outgoing telephone number exists, including the message called the selective incoming restriction number in the location response message and transmitting the message to the exchange;
And, when the switch receives a location response message corresponding to the selective forwarding restricted phone number from the home location register, performing a call setup procedure with a forwarding number registered in the forwarding restriction list of the home location register. It is characterized by.

Registering a selective call forwarding service with a subscriber in the system;

Recognizing a call attempt to the registered subscriber;

Confirming whether the called party is a subscriber to the restricted call service;

And confirming that the calling number exists in the called restriction list if the called restriction service registered subscriber is found, and performing the incoming call procedure to another destination when the calling number exists in the called restriction list.

Preferably, if the receiver is not a subscriber to the incoming call protection service or the calling party does not have a calling number in the call restriction list, characterized in that it comprises the step of performing a normal call processing procedure.

Preferably, the selective call forwarding service registering subscriber and the call forwarding list are registered in advance by a subscriber who wants an additional service in a home location register.

Preferably, the call forwarding target for the telephone number of the calling subscriber belonging to the selective call restriction list includes a specific announcement and tone, a voice mailbox, and a specific telephone number.

Preferably, the selective call restriction list registers a specific calling party number to be restricted through the terminal and the Internet.

Preferably, it is possible to classify the caller's telephone number registered in the call restriction list, so that the incoming call procedure can be performed with different switching numbers.

Preferably, the call forwarding number corresponding to the caller's telephone number registered in the call forwarding list may be selected by the called party who wants to perform call forwarding service.

Referring to the attached call restriction service method according to the present invention as described above with reference to Figures 3 and 4 as follows.

Referring to FIG. 3, the mobile communication subscriber registers with the selective call restriction service provided by the mobile communication system so as to selectively receive the incoming call (S301). At this time, when registering a service, the subscriber's telephone number to be restricted is registered. Here, the incoming call restriction list may be a landline telephone number of the calling subscriber, a mobile network subscriber number, or the like.

Then, when another subscriber attempts to call the selective call forwarding service registered subscriber (S302), the system checks whether the telephone number of the called party (recipient) corresponding to the call of the other subscriber is a selective call forwarding service registered subscriber ( S303).

If the called subscriber is a selective call restriction service registered subscriber, the system checks whether the calling party number exists in the called restriction list registered by the called subscriber (S304).

If the caller's phone number exists in the call restriction list, the call forwarding procedure is performed to another conversion number (S305).

In this case, if the receiver is not the selective call restriction service registered subscriber or the caller's telephone number does not exist in the call restriction list, the receiver performs the incoming call procedure normally so that the call can be made with the called subscriber (S306).

In more detail, the present case and the case that do not exist in the registration list of the selective call restriction service will be described with reference to FIG. 4.

A specific subscriber of the telecommunication system applies for an additional service by registering an incoming call restriction service at the home location register. The incoming call list here corresponds to the calling telephone number.

In addition, the subscriber's call list may be registered at the time of initial subscriber registration, such as call waiting service when the subscriber presses a number to be called by the subscriber together with a specific code (eg, * 90) of the terminal. Then, the home location register 330 manages the incoming call subscriber list of the service subscriber. In an embodiment, the subscriber to the do not disturb service may register a call restriction list on the Internet. The subscriber information registered in the call restriction list may be, for example, a company / home phone number of the other party.

Then, when another calling subscriber 310 attempts to call (S311), the switchboard (MSC) 320 requests the location information from the call attempt message and the calling telephone number to the home location register (HLR) 330. Included in the message and transmitted (S312).

The home location register 330 checks whether the corresponding subscriber of the received incoming phone number is a call forwarding service registered subscriber (S313). (S314).

If the outgoing call number exists in the incoming call restriction list, the message including the message called the restriction number by the selective call restriction is included in the location response message (Location Req_Ack) and transmitted to the exchange 330 (S315). The incoming call setting procedure is performed with the set forwarding number (S316).

In this case, the call forwarding number may be replaced with a specific announcement and tone, or may be connected to a voice mailbox, a virtual telephone number provided on the Internet, or a specific whistleblower or a national investigative agency.

As a result, the calling subscriber on the call restriction list does not know whether the called party performs the call restriction and does not go through a separate password confirmation procedure and thus does not occupy the line.

On the other hand, when the home location register 330 is not a subscriber to the incoming call restriction service or the caller ID does not exist in the call restriction list, the home location register 330 notifies to the exchange including the call forwarding number in the location response message (Location Req_Ack) (S317). The exchange 320 performs a general incoming call procedure (S318).

As described above, according to the present invention, since the caller performs the service as another transfer number when the caller is present in the call restriction list, the incoming call may be restricted to only some calling subscribers while not recognizing that the caller is forwarded.

In addition, since the call forwarding can be made to another number, the subscriber who tries to call frequently can be made aware of the fact that the current caller is trying to restrict the call forwarding subscriber and can forward the call.

In addition, since the password verification procedure is not performed as in the related art, it is not necessary to occupy unnecessary radio resources and communication lines of the exchange, thereby preventing excessive line occupation of the system.

As an example, an outgoing subscriber who attempts illegal advertisements, public relations, or socially emotional abnormal calls (including Internet calls and mail services) may be forwarded so that the caller can be diverted to a specific whistleblower or phone of a national investigative agency. Can be. That is, the call forwarding service may be performed by switching to an arbitrary call forwarding number corresponding to the calling party's telephone number corresponding to the call restriction.

In an embodiment, the additional service subscriber may directly select different call forwarding numbers for each call restriction calling party number, so that the additional service subscriber may perform the call forwarding procedure to the selected call destination.

As another example, the selective call forwarding service of the present invention may provide an additional service as a selective call forwarding service, which registers only specific subscribers in the call forwarding list, and the registered subscribers receive the service. To allow incoming calls to be performed.

As described above, the selective call forwarding service method according to the present invention can improve the quality of additional services by selectively allowing call forwarding subscribers to perform call forwarding to another call forwarding number without recognizing the call forwarding.

In addition, there is no need to occupy a radio resource and a communication line of the exchange because it does not perform a separate password verification procedure when the incoming call is restricted, thereby preventing the excessive line occupancy of the system, thereby making it possible to effectively utilize the line resource.

In addition, an outgoing subscriber who attempts illegal advertisements, promotions, or social emotional abnormal calls may have a call forwarding effect so that the caller can be diverted to a specific whistleblower or a national investigation agency telephone.
