In addition, the method for providing an answering service of a mobile communication system according to another embodiment of the present invention activates the answering service according to the request of the answering machine subscriber, and sends the answering service status bit according to the answering service activation to the HLR. Storing; Storing, by the MSC accepting the call of the answering service subscriber, the subscriber profile and the answering service status information received from the HLR in a subscriber database according to the location registration request of the answering machine subscriber; When the calling subscriber attempts to call the called party number, the calling MSC performs a basic call setup procedure to establish a call path with the anchor MSC where the called party is roaming; A new incoming call that has been converted to a service right according to the handoff procedure when the called subscriber moves to another service area while the call path between the calling MSC and the anchor MSC is established and paging to the called subscriber by the anchor MSC. Receiving, by the MSC, an answering machine code input from the called party and a digit indicating a call rejection state; Transmitting, by the called MSC, the received auto-answer service code and a digit indicating a call rejection state to the anchor MSC by including in a flash request message; Determining, by the anchor MSC, a subscriber database by the called subscriber number to determine whether an answering service of the called subscriber is activated; And when the answering service is activated, the anchor MSC analyzes the digits included in the flash request message and performs announcement broadcast on the called party's rejection status to the calling party. Characterized in that.

Hereinafter, with reference to the accompanying drawings will be described in detail a method for providing an answering service of a mobile communication system according to a preferred embodiment of the present invention.

In order to implement the method for providing an answering service in a mobile communication system according to the present invention, first, the authority for the answering service must be granted and the answering service must be activated.

First, in order to be authorized for the answering service, a network operator or a service provider examines whether the answering service is provided to the subscriber and determines that the provision of the service is appropriate. Authorization is provided through the Interface.

As described above, after being authorized for the answering machine, the answering machine is activated to receive the authorized answering service. The answering service is only activated when authorization is being performed, or according to the subscriber setting. Can be activated.

On the other hand, the deletion of authority for the answering service may be made for a subscriber's request or for operational reasons.

As mentioned above, changes to subscriber options, such as authorization and activation for answering machine services, follow ANSI-41-C's Basic Feature Processing.

As described above, various kinds of information about the auto attendant service set according to the basic feature processing of ANSI-41-C are managed by the Home Location Register (HLR), and the auto attendant service status bit is stored in the subscriber profile database of the HLR. Etc. are stored.

In addition, information on the activation / deactivation status of the answering machine, information on when the answering service is activated and sending an announcement, and information on when and how long the answering service is activated are recorded in the call detail record. Are stored in.

2 is a road for explaining a location registration procedure of a mobile communication terminal, when an answering machine subscriber moves to an area and requests location registration with an MSC (S10), the MSC includes the subscriber number of the subscriber who requested a new location registration. The VLR receives a location registration request message (REGNOT; RegistrationNotfication) to the VLR (Visitor Location Register) (S12), and the VLR received the location registration request message (REGNOT) from the MSC receives the location registration request message (REGNOT) received from the MSC. Transmit to HLR (S14).

As described above, the HLR having received the location registration request message (REGNOT) from the MSC through the VLR uses the subscriber number included in the location registration request message (REGNOT) and the subscriber profile of the subscriber and the auto attendant service of the subscriber. A CFI (Calling Feature Indicator) parameter that specifies the authorization and activation states, and a response message (regnot) including the searched subscriber profile is transmitted to the VLR (S16).

The VLR transmits a response message (regnot) for the location registration request received from the HLR to the MSC (S18), and the MSC receiving the response message (regnot) for the location registration request from the HLR via the VLR is the location received from the VLR. After storing the subscriber profile and the CFI parameters included in the response message (regnot) to the registration request in the subscriber database, and transmits a response to the location registration request that the location registration change is completed (S20).

3 and 4 are roads illustrating a method for providing an answering service in a mobile communication system according to an embodiment of the present invention, when a calling party A attempts to call a called party number (S30), the calling MSC is a basic call. The setup procedure is performed to establish a call path with the destination MSC (S32).

As described above, when a call path between the originating MSC and the destination MSC is established, the destination MSC performs paging to the called party (S34), and the digit corresponding to the answering machine status of the called party and the answering party of the called party is received from the called party. It is transmitted (S36). That is, when the called MSC performs paging to the called subscriber and the called subscriber terminal rings, the called subscriber who listens to the call signal does not hook off to the call signal and the answering machine code (for example, * 05) Enter a digit (for example, 2) that corresponds to your call rejection status.

Meanwhile, the called MSC searches the subscriber database by the called subscriber number, and determines whether the answering machine service of the called subscriber is activated (S38 and S40).

When the answering service of the called party is activated as a result of the determination of step S40, the digits corresponding to the call rejection status of the called party received with the answering machine code from the called party are analyzed and the called party is called to the calling party. The announcement broadcast is performed for the incoming call rejection state (S42).

5 and 6 are roads illustrating a method for providing an answering service in a mobile communication system according to another exemplary embodiment of the present invention, and a case where a called party in a call moves to another service area.

First, when the calling party A attempts to call the called party number (S50), the calling MSC performs a basic call setup procedure to establish a call path with an anchor MSC where the called party is currently roaming. If the call path between the originating MSC and the anchor MSC is established (S52), the anchor MSC performs paging to the called party (S54).

As described above, when a calling channel is established between the calling MSC and the anchor MSC and the anchor MSC is paging to the called subscriber, when the called subscriber moves to another service area, a new channel (the service where the called subscriber is located). A hand off procedure is performed to allocate a channel allocated to a region so that the call path can be maintained (S56 and S58). Here, even if the MSC accepting the call of the called party is controlled, the control of call processing, billing, etc. is managed by the anchor MSC to which the first call is configured, so that the first configured line is not restored but the circuit connected to the new incoming MSC is added. Make sure the channel continues.

As described above, the recipient MSC, which has switched the service right by performing the handoff procedure, receives a digit corresponding to the answering state of the called party and the answering party from the called subscriber from the called subscriber (S60). That is, when the anchor MSC performs paging to the called subscriber and the called subscriber terminal rings, the called subscriber who hears the call signal does not hook off to the call signal and the answering machine code (for example, * 05) Enter a digit (for example, 2) that corresponds to your call rejection status.

As described above, the destination MSC receiving the answering machine code and the digit corresponding to the called party's rejection status from the called party receives the digit corresponding to the answering state of the called party and the called party's rejection status. The anchor MSC, which is included in the flash request message FLASHREQ (FlashRequest), is transmitted to the anchor MSC (S62), and the anchor MSC having received the flash request message (FLASHREQ) transmits a response message (flashreq) to the destination MSC (S64).

Thereafter, the anchor MSC searches the subscriber database by the called subscriber number (S66), and determines whether the answering machine service of the called subscriber is activated (S68).

As a result of the determination in step S68, when the automatic answering service of the called party is activated, the digits corresponding to the rejection state of the called party included in the flash request message (FLASHREQ) received from the called MSC are analyzed. In step S70, the announcement broadcast is performed on the called party's rejection status of the called subscriber.

The method for providing an answering service of the mobile communication system of the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea of the present invention.

According to the method for providing an answering service of the mobile communication system of the present invention as described above, when there is a call requesting an answering service to the answering service subscriber, if the answering service is activated, the call rejection status digit received from the called subscriber is received. By analyzing and performing a guide broadcast on the call rejection state to the calling party, it is possible to perform the guide broadcast on the call rejection state without turning off the mobile communication terminal.
