The present invention relates to a method and apparatus for interworking with various voice supplementary services when a call with a counterpart is not made for an outgoing call.

Hereinafter, a call processing process will be described when a call setup with a conventional called party fails with reference to the accompanying drawings.

1 is a signal flow diagram schematically illustrating a processing process when a call setup with a conventional called party fails.

A detailed process will be described with reference to FIG. 1. The calling subscriber tries to make a call to the called subscriber (S10). At this time, the terminal of the called subscriber is set up due to various reasons, for example, when the power is turned off (Busy), busy, no answer or out of range. If it is impossible (S11), the source switching apparatus plays the announcement and notifies the calling subscriber that the called party cannot answer the call (S12).

For example, if the incoming subscriber's terminal is powered off (Power Off) from the calling exchange, "Your phone is turned off and connected to your voicemail. After you connect, you will be charged." If the incoming subscriber's terminal is busy (Busy), "You are busy and you will be connected to your voicemail. You will be charged." A guide comment such as this may be output. In addition, if the called subscriber's terminal is No Answer or Out of range, "You can't answer the phone and you will be connected to your voicemail. After you connect, you will be charged." A guide comment such as

If the calling subscriber does not terminate the call after outputting the announcement, the calling exchange device switches the call to the voice mailbox of the called subscriber so that the calling subscriber can leave a voice message.

Referring to the conventional call processing process, when the calling subscriber is not able to make a call with the called subscriber, the calling subscriber can transmit the message using only the voice mailbox. The voice mailbox was merely a passive way of waiting for a called party to receive the message. Therefore, there was a need to find ways to increase the success rate of calls and to reduce repetitive efforts to make calls with the called party.

In addition, if the calling subscriber leaves a voice message in the voice mailbox, the called subscriber receives a short message (SMS) indicating that the calling subscriber's voice message has arrived in the voice mailbox in order to hear the voice message left by the calling subscriber. You must call (Call Back Number) and enter your password before you can hear voice messages. Due to the complicated procedure of delivering such a voice message to the called subscriber, the utilization rate of the voice mailbox is low recently.

In addition, in case of an outgoing subscriber, an incomplete call increases by hearing the announcement that the incoming subscriber cannot talk with the called subscriber provided by the exchange in the incapable state of the existing called subscriber. The increase in incomplete calls is inevitable for operators to reduce their basic voice call sales.

In the case of a message call, the calling subscriber can conveniently deliver a voice message to the called subscriber by pressing the feature code and the called subscriber's number. However, when the calling subscriber cannot call the called party and can't talk with the other party, there is an inconvenience in using the caller who needs to hang up the current call and press the feature code and the called number again to send a message call to the called party.

In the case of a reservation call, it is possible to make a call with the called party at a certain time in the future. However, when a call is made by pressing the phone number and the call button, the called party may call for reasons such as Power Off, Busy, No Answer, and Out of range. There is no easy way for an outgoing subscriber to schedule a call after a certain period of time.

Messaging System) 180 is included.

3 is a diagram schematically illustrating a processing process when a called subscriber cannot answer a phone call according to an exemplary embodiment of the present invention.

Referring to Figure 3, looking at the specific process as follows. The calling subscriber 100 attempts to make a call to the called subscriber 200 (S110). At this time, the called subscriber 200 may make a call due to various reasons, for example, when the power is off (Busy), busy, no answer, or out of range. If it cannot be received, the calling exchange apparatus 120 provides the changed announcement to the calling subscriber 100 to select a desired service (S120). For example, if the call fails to connect through the calling subscriber (100) terminal "You can not answer the call. Message call transmission is 1, call reservation is 2, voice mail 3 times, short message. Press 4 to leave, 5 to leave a video message, and press 6 if you do not wish to receive the service.

The calling subscriber 100 who listens to the announcement selects a method of providing a desired service. That is, the calling subscriber 100 waits for a dual tone multi frequency (DTMF) input of the calling subscriber 100 (S130). When the calling subscriber 100 inputs the DTMF, four different services may be provided depending on the selection. When the calling subscriber 100 wants to transmit a voice message (message call), the calling exchange device 120 transmits a call to the message transmitting device (message call IP server) 140 (S140). If the calling subscriber 100 wants to make a call reservation, the calling switching device 120 transmits the call to the call reservation device (reserved call IP server) 150 (S150). If the calling subscriber 100 wants to access the voice mailbox 160, the calling exchange apparatus 120 transmits the call to the voice mailbox (VMS server) 160 (S160). When the calling subscriber 100 wants to deliver the phone number, the calling subscriber 100 transmits the call to the short message transmitting device (SMS server) 170 (S170). When the calling subscriber 100 wants to transmit a video message, the calling exchange apparatus 120 transmits the call to the video message transmitting apparatus (MMS server) 180 (S180).

However, when the calling subscriber 100 does not input DTMF in step S130, the call is transmitted to the voice mailbox (VMS server) 160 after the announcement is output as in the case where the conventional call connection is not made (S190).

4 is a signal flowchart illustrating a process of interworking with voice additional service according to a terminal state of a called subscriber according to an embodiment of the present invention.

Referring to FIG. 4, when the terminal state of the called subscriber 200 is turned off (Power Off), or when the call is not allowed (Out of range), or in a call (Busy), the voice additional service interworking process This is done. The specific process is as follows.

The calling subscriber 100 requests the call setting to the calling switching device (MSC) 120 through the call (S210). The originating exchange device 120 queries the subscriber registration device 110 for the location of the called subscriber 200 (S220). In this case, when the state of the called subscriber 200 does not receive a call, the subscriber registration device 110 requests a call transfer to the calling exchange device 120 (S230). The originating exchange device 120 provides a new Voice Guidance that the called party 200 cannot receive the call and requests the DTMF input of the calling party 100. The calling subscriber station waits for a response of the calling subscriber 100 corresponding to the request signal (S240). If the calling subscriber does not press DTMF, the call can be transferred to the VMS according to the conventional method or the call can be transferred to the corresponding system according to the service definition of the service provider.

On the other hand, when the calling subscriber 100 inputs the desired service through the DTMF (S250), the calling switching device 120 transmits the call to the subscriber registration device 110 to the voice additional equipment based on the DTMF input by the user. A new additional device number is requested (TRANUMREQ: Transfer To Number Request) (S260). In response, the subscriber registration device 110 responds to the calling exchange device 120 with the number of the corresponding voice additional device (S270). The originating exchange device 120 is a new additional device, for example, voice message delivery device (message call IP server) 140, call reservation device (reservation call IP server) 150, voice mailbox (VMS server) 160 The call is transmitted to the short message transmitting device (SMS server) 170, the video message transmitting device (MMS server) 180, and the like (S280). The calling subscriber 100 uses a function provided by each corresponding device (S290). After the use of the additional service through each corresponding device is terminated, the calling subscriber 100 ends the call (S300). Thereafter, the originating switching device 120 terminates the call with the voice adding device (S310).

5 is a signal flowchart illustrating a process of interworking with voice additional service according to a terminal state of a called subscriber according to another embodiment of the present invention.

Referring to FIG. 5, when the called subscriber 200 does not answer the call (No Answer), an interworking process with the voice additional device is performed. The specific process is as follows. The calling subscriber 100 makes a call and requests the call setting to the calling switching device 120 (S410). The originating exchange device 120 queries the subscriber registration device 110 for the location of the called subscriber 200 (S420). The subscriber registration device 110 transmits the location of the incoming exchange device 130 to the originating exchange device 120 (S430). The originating exchange device 120 requests a call setup of the originating subscriber 100 to the destination exchange device 130 based on the information transmitted from the subscriber registration device 110 (S440). Upon receiving the call setup request signal, the destination exchange apparatus 130 attempts to set up a call with the called party 200, and when the called party 200 does not respond to the call setup attempt, the idea of the present invention is applicable. (S450). If the called party 200 is not answered, the called exchange device 130 requests a call transfer to the calling exchange device 120 (S460). The originating exchange device 120 receiving the call transfer request signal provides a new announcement to the calling subscriber 100 that the called subscriber 200 cannot receive a call and waits for DTMF input of the calling subscriber 100. do. If the calling subscriber does not press DTMF, the call may be transferred to the VMS according to the existing method, or the call may be transferred to the corresponding system according to the service definition of the telecommunication operator (S470). In accordance with the contents of the new announcement, the calling subscriber 100 inputs a desired service through DTMF (S480). The originating exchange apparatus 120 requests a new number for transmitting a call to the voice additional equipment to the subscriber registration apparatus 110 based on the DTMF input by the originating subscriber 100 (TRANUMREQ: Transfer To Number Request) (S490). The subscriber registration device 110 returns the number of the voice additional device to the calling switching device 120 in response (S500). The originating exchange device 120 that fails to set up a call with the called party 200 ends the call set up with the called exchange device 130 (S510). The originating exchange device 120, which has completed call setup with the incoming exchange device 130, is a new additional device, for example, a voice message transmission device (message call IP server) 140, a call reservation device (reserved call IP server) 150, a short message transmitting device (SMS server) 170, a voice mail box (VMS server) 160, a video message transmitting device (MMS server) 180 and the like to send a call (S520). A call is established between the originating exchange device 120 and the voice additional device through the call transfer signal, and the calling subscriber 100 may use a function provided by each device through the set call (S530). The calling subscriber 100 using the function provided by the voice additional device ends the call (S540). Thereafter, the originating exchange device 120 terminates the voice additional service interworking process by terminating the call with the voice additional device (S550).

6 is a signal flow diagram illustrating a process of receiving and detecting a DTMF at the time of providing a voice mail change message in an exchange apparatus according to a preferred embodiment of the present invention.

The above process will be described in detail with reference to FIG. 6.

If the call setup fails with the called subscriber 200 attempted by the calling subscriber 100 from the MSC, "The customer cannot answer the call. Message call transmission is 1 time, call reservation is 2 times, voice mailbox. Press 3 to connect, 4 to leave a short message, 5 to leave a video message, or 6 if you do not wish to receive the above service. " The voice mail conversion comment, such as the like, is played back (S610). At this time, the exchange device exists in the DTMF reception waiting state, and waits until the user waits for the DTMF event or receives the announcement announcement end event (S620). When a predetermined signal is received from the calling subscriber 100, the switching device determines whether the received event is a DTMF event (S630). If the received signal is not a DTMF event, the process proceeds to step S640. If the received signal is a DTMF event, the process proceeds to step S650.

First, when the received signal is not a DTMF signal, the exchange apparatus checks whether the received event is a announcement announcement end event (S640). If the received event matches the announcement announcement end event, the call is transferred to the voice mailbox 160 (S720), otherwise, the call returns to the standby state of step S620.

If the received signal is a DTMF signal, the exchange apparatus attempts to set up a call according to an instruction included in the received DTMF event. In more detail, the switching device requests the subscriber registration device 110 using the TRANUMREQ signal to request the number of the voice additional device to set the call (S650). In this case, Redirection Reason in TRANUMREQ can be defined and used. When the switching device receives the number of the voice additional device transmitted in response from the subscriber registration device 110, the call is routed to each voice additional device according to the number (S660).

 When the originating subscriber 100 makes the DTMF input, the call is set to a different voice additional device for selection. For example, when the calling subscriber 100 wants to deliver a voice message (message call), the calling exchange device 120 transmits a call to the message transmitting device (message call IP server) 140 (S670).
