Description

Subscriber Matching Apparatus Of Voice Mailing System

The present invention relates to a voice mailbox of a switching system, and more particularly, to a subscriber matching device itself without control of a main processor card that stores voice message data and manages call processing for a specific portion of a voice message desired by a user connected to the call. A subscriber matching device of a voice mailbox system for providing a repeat listening service.

As can be seen in FIG. 1, the voice mail box of the conventional exchange system is mounted on a main processor card including a main processor unit 70 and a separate self from the main processor card, and includes a control unit 10, A subscriber matching device comprising a call processing unit 20, a voice processing unit 30, a voice memory unit 40, a DTMF processing unit 50, and a buffer 60.

The control unit 10 in the subscriber matching device transmits the call connection request information of the user input through the PCM highway to the main processor unit 70 to switch the corresponding link according to the control signal by the main processor unit 70. It connects the user with the voice mailbox of the switching system and controls the overall operation for sending the voice message required by the user.

The call processor 20 is connected to the main processor unit 70 through a control bus (C-BUS), and calls to the main processor unit 70 according to signals applied from the controller 10 and the DTMF processor 50. Perform general operations related to processing.

The voice processing unit 30 compresses the PCM voice message input from the subscriber via the received PCM highway RXPCM to a predetermined state under the control of the controller 10 and stores the compressed voice message in the voice memory unit 40, and stores the voice memory unit ( It is responsible for the function of restoring the compressed PCM voice message in a predetermined state that is authorized to send to the user in 40) to a general PCM voice message and transmits it to the user through the transmitting PCM highway (TXPCM).

The voice memory unit 40 is connected to the main processor unit 70 through a data bus D-BUS, stores a voice message applied from the main processor unit 70, and then applies the voice message to the voice processor 30. The voice message compressed and applied by the voice processor 30 is stored and then transmitted to the main processor unit 70 to be stored in the voice storage means.

The DTMF processing unit 50 analyzes a DTMF signal applied through the receiving PCM highway RXPCM and applies information about the DTMF signal to the control unit 10 and the call processing unit 20.

The buffer 60 is connected to a transmit / receive PCM highway (TXPCM) (RXPCM) and a system that accepts DTMF signals and voice messages of subscribers or users authorized through the receiving PCM highway (RXPCM) and voice messages transmitted to subscribers or users. It is responsible for the function of synchronizing with the clock SYSCK and transmitting it.

The operation of the voice mailbox of the conventional switching system having the functions as described above is as follows.

When a signal for requesting a call connection from any user is detected in the buffer 60 through the receiving PCM highway RXPCM, the buffer 60 synchronizes with the system clock SYSCK and transmits a signal for requesting a call connection to the DTMF processing unit. It is applied to 50.

When the DTMF processing unit 50 analyzes the DTMF signal applied in synchronization with the system clock SYSCK and applies the information to the control unit 10, the control unit 10 analyzes the applied information through a set algorithm to call. The call processor 20 is controlled by determining that the signal is a request for setting to connect a call between the main processor unit 70 and the user.

In the call connection state as described above, the guidance message for using the voice mail transmitted from the main processor unit 70 is stored in the voice memory unit 40 side via the data bus D-BUS, and then in the voice processing unit 30 side. When applied, the voice processing unit 30 restores the PCM voice message compressed and applied to a predetermined state into a general PCM voice message and applies it to the buffer 60 side.

At this time, the buffer 60 transmits a guide message for the use of the voice mailbox authorized by the voice processing unit 30 to the user side connected to the call through the transmission PCM highway TXTXM in synchronization with the system clock SYSCK.

When the user receiving the guide message for using the voice mailbox inputs a DTMF signal for selecting a desired service, the DTMF processing unit 50 analyzes the DTMF signal applied in synchronization with the system clock SYSCK and then controls the analyzed information. Is applied to (10).

At this time, the controller 10 analyzes the applied information through a set algorithm and applies information to the main processor unit 70 through the call processor 20 to transmit a voice message desired by the user.

Accordingly, when the main processor unit 70 accesses the corresponding voice message selected by the user from the voice storage means and applies the voice message to the voice processing unit 30 through the voice memory unit 40 through the data bus D-BUS. The voice processing unit 30 restores the applied compressed PCM voice message to the original PCM voice message, synchronizes the synchronization with the buffer 60, and transmits the same to the user connected through the transmission PCM highway TXTXM.

As described above, when a user wants to listen to an arbitrary part repeatedly while a voice message requested by the user is being transmitted, a DTMF signal inputted when a user inputs a DTMF signal for selecting a function of repeated listening using his terminal. Is synchronously adjusted by the buffer 60 and applied to the DTMF processing unit 50.

At this time, the DTMF processing unit 50 analyzes the information of the DTMF input and then applies the information to the control unit 10 side, the control unit 10 receives the information for requesting the repeated transmission of the voice message currently sent to the call processing unit ( 20) to the main processor unit 70.

Accordingly, the main processor unit 70 accesses the voice message token of the corresponding part from its storage means in accordance with the repeated listening request from the user and reloads the voice memory unit 40 through the data bus D-BUS. Therefore, the voice processing unit 30 restores the compressed voice message and transmits the same to the user who requests repeated listening in synchronization with the buffer 60.

The voice mailbox of the conventional switching system as described above can repeatedly listen to the voice message currently being sent according to the user's request, but in order to request the repeated listening of the voice message, the user must execute the corresponding function selection every time. Accordingly, the main processor unit must continuously reload the corresponding voice message into the voice memory unit, so that a load is applied to the main processor unit in the state where a plurality of channels are occupied and used. There was a problem that the same function as the initial sending operation of the message should be repeatedly performed.

In addition, in the case of a voice message repeatedly transmitted according to a user's request, it is possible to listen indefinitely in one token unit of the voice message, but there is a problem in that it is not possible to repeatedly listen to a specific part of the voice token.

The present invention has been made in view of the above-described general problems, and an object thereof is to provide repeat listening to a specific part of a voice message currently provided in a voice mailbox system, and to provide a repeat listening service for a specific part of a voice message. The subscriber matching device itself is operated without the control of the processor unit to provide efficiency in the operation of the system.

Since the general procedure of sending a voice message according to a call connection request from an arbitrary user and the request of the corresponding user is the same as the conventional operation described above, the description thereof will be omitted, and a specific portion of the voice message transmitted will be omitted. Only the operation of repetitive listening is explained.

The user who is connected to the call does not recognize the voice message you are listening to while listening to any voice message in the voice mailbox, or it is predefined by using a button provided on his terminal to listen to a certain part repeatedly. When the specific DTMF tone is inputted, the DTMF processing unit 50 in the subscriber matching device analyzes the DTMF signal of the user and then applies a function selection signal to the control unit 10 side.

The control unit 10 is a voice message currently sent to the main processor unit 70 connected to the control bus (C-BUS) via the call processing unit 20 according to the function selection signal applied from the DTMF processing unit 50. Repetitive delivery of

At this time, the main processor unit 70, which has been requested to repeatedly transmit the voice message, loads the token of the voice message into the voice memory unit 40 via the data bus D-BUS and stores the voice message unit 30. Restores the compressed PCM voice message and then applies it to the voice token specifying portion processing unit 80 to transmit the compressed PCM voice message to the PCM highway, which is a serial bus. As shown in FIG. The first mux 82 multiplexes the output port of the voice message to be output from the voice processing unit 30 according to a control signal of the control unit 20 applied through the arbitration of the register unit 81. The voice message output from the processor unit 70 is repeatedly output to the user.

As described above, when the user inputs a start signal for designating a specific part as a signal of the DTMF set to repeatedly listen to a specific part of the voice message using his terminal while listening to the voice message, the DTMF processor 50 When the DTMF signal that is synchronized and adjusted through the buffer 60 is analyzed and applied to the control unit 10, the control unit 10 applies the corresponding information to the main processor unit 70 through the call processing unit 20. Keep the call from ending.

The signal / CS and the write signal / WE are activated and the read signal / RD is deactivated so that the voice message for the specified specific portion is stored at the designated address address of the memory unit 90.

As described above, when a time point for repetitive listening is selected for a specific part of the voice message transmitted as described above, a DTMF signal for which the user designates the last part using his terminal while the voice message is stored from the corresponding time point is stored. When inputted, the DTMF processing unit 50 analyzes the corresponding signal and applies the information to the control unit 10, so that the control unit 10 applies the control signal to the voice token specifying unit 80 to store the memory unit. 90 determines the last part of the voice message that is stored for repeated listening.

When the start point and the end point for the specific part of the voice message for repeated listening are determined by the user's selection, and the corresponding voice message is stored in the memory unit 90 made of SRAM, the controller 10 is shown in FIG. 3. The first mux 82 is controlled through the registered register 81 so that an output port of the first mux 82 is applied from the memory unit 90 through the serial / parallel converter 85 to transmit the PCM. The port is determined to be output to the highway TXPCM, and the address generator 84 is cleared to control the port to be repeatedly transmitted from the first part of the stored voice.

A user connected to the call through the first mux 82 by designating a stored voice message and controlling the serial / parallel conversion unit 85 to convert the PCM voice message in parallel according to the specified order into a serial PCM voice message. Send it out repeatedly.

As described above, when the user does not want to listen to the repeating voice repeatedly while the voice message stored in the memory unit 90 in the subscriber matching device is repeatedly transmitted, a DTMF signal for terminating the transmission of the preset service using his terminal is received. The DTMF processor 50 analyzes a signal input through the receiving PCM highway RXPCM and applies the information about the signal to the controller 10.

At this time, the control unit 10 reports the information on the end of the repeated listening to the main processor unit 70 through the call processing unit 20 and at the same time through the arbitration of the register unit 81, the first and second mux 82 Multiplex (83) to maintain the original service port.

As described above, according to the present invention, when a repeat listening request is detected for a specific part of a voice message transmitted from a voice mailbox, the voice message is recorded for the specific part corresponding to the subscriber matching device itself without controlling the function of the main processor unit. Since it is automatically transmitted next, it does not put a burden on the main processor unit to provide efficiency and stability in the operation of the system, and provides various services for re-listening and repetitive listening in the voice remission service and the answering machine service system. .
