Abstract

PURPOSE: A voice resources replacement method for VMS(Voice Mailing System) is provided to double a common memory in VMS, so that the user does not make the operation of VMS interrupt when replacing the voice resources, thereby enhancing the reliability of the users to the service. CONSTITUTION: A call processing process approaches to a common memory segment produced by a manager and then outputs a guide voice necessary to a service to a designated time slot(S11). During the service, when it is necessary to change the guide voice(voice resources)(S12), the manager copies or stores the newly prepared voice file to a file system(S13) and informs the change of the voice file to the manager(S14). Thereafter, the manager produces a new common memory segment(S15), reads the voice file from the file system and then stores the file to the new common memory segment(S16). The call processing process uses the voice resources stored to the new segment(S17). The call processing process can approach two common memory segments.

Description

VOICE RESOURCE CHANGING METHOD FOR VOICE MAILING SYSTEM}

The present invention relates to a voice mailing system, and more particularly, to a method of replacing a voice resource of a voice mailing system so as not to interrupt operation of the mailing system.

In general, the voice mailing system (VMS) has a function of recording a mailbox, listening to a message, and notifying a user by assigning a mailbox by department, individual, or function. In this case, the indirect call is made in the system.

In other words, the VMS service is a service using the system as described above. The VMS service stores a voice of a talker in a mailbox by using a computer's data processing capability, and enables a receiver to check and listen to a message anytime, anywhere. .

Although not attached to the drawings, the voice mailing system generally includes an operating system that supports shared memory; A file system managed by the disk drive and the operating system; Voice data files recorded by ADPCM (Adaptive Delta Pulse Code Modulation) or other compression method; An application program that performs a function of loading the voice data file into a shared memory; An application program for outputting a voice resource loaded in the shared memory to a designated time slot of a time division multiplexing (TDM) bus of a voice mailing system; Include network paths outside the system to replace voice resources.

Referring to the operation of the conventional voice mailing system made as described above are as follows.

Once a voice mailing service provider attempts to replace voice resources as needed, the voice mailing service is stopped even while the service user is using the voice mailing service.

Therefore, after that, the service user cannot use the voice mailing service.

Then, after stopping the service as described above, the service provider stores the voice data files recorded by ADPCM or other compression method in a file system (not shown) in the voice mailing system through a network path or the like.

Next, the application program of the system which has been stopped is restarted to load new voice files stored in the file system into the shared memory, and when all the voice files are loaded into the shared memory, the normal voice mailing service can be performed.

That is, when the replacement of the voice resource (voice data file) is completed as described above, the voice mailing service by the new voice resource can be used from that point on.

However, in the conventional voice mailing system, it is not possible to provide a voice mailing service when the voice resource is replaced, thereby reducing the operating time of the system, and thus reducing the reliability of the system.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and by duplexing the shared memory in the voice mailing system, the user does not stop the operation of the voice mailing system when the voice resource is replaced. Its purpose is to provide a voice resource replacement method of a voice mailing system that improves reliability.

1 is a flow chart showing a voice resource replacement process of the voice mailing system according to the present invention.

In order to achieve the above object, the present invention provides a voice mailing system comprising: a first step of copying or storing a new voice resource in a file system and informing the manager when a voice resource is changed during the operation of a mailing service; ; A second step of the manager recognizing that the voice resource is changed in the step, generating a new shared memory segment (second segment) and reading and storing the voice resource in the file system; Generating an index for the second segment and notifying the call processing process to perform a call processing process using the voice resource stored in the second segment; A fourth step of searching for a call processing process that no longer uses the existing shared memory segment (first segment) and removing the first segment from the process area; A fifth step of completely removing the first segment in the system through the operating system (OS) when all the first segment is removed from all call processing process areas; Since there is a request to change the new voice resource, characterized in that it comprises a sixth step of performing the above process repeatedly.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart showing a voice resource replacement process of the voice mailing system according to the present invention.

As shown in the drawing, once an operator copies or stores voice files (voice resources) to be provided to a service for initial startup of the system to a file system (not shown) in the system through a network path and other methods, and provides a service. Start various applications for.

In this case, the shared memory manager (hereinafter referred to as a manager) among the application programs accesses a file system (not shown) in which a voice file is stored, collects information on voice files (voice resources), and shares a shared memory segment (first segment). Create

Next, voice files are loaded into the shared memory segment (first segment), and an index is created for efficient access to the voice file.

Next, the manager starts an application program (hereinafter referred to as a call processing process) for outputting voice files (voice resources) to a designated time slot of the TDM bus.

At this time, the call processing process accesses the shared memory segment (first segment) generated by the manager and outputs the guide voice necessary for the service to the designated time slot (S11).

Next, when it is necessary to change the guide voice (voice resource) of the service during the service operation as described above (S12), the operator copies or stores the newly prepared voice file (voice resource) to a file system (not shown) (S13). In step S14, the manager notifies the manager that the voice file has been changed.

Accordingly, after recognizing that the voice file has been changed, the manager creates a new shared memory segment (second segment) different from the shared memory segment currently being accessed by the call processing process (S15), and then the voice file in the file system. The data is read and stored in the newly created shared memory segment (second segment) (S16).

Of course, in this case, a separate index is created for efficient access of the voice file, and the fact (new shared memory segment (second segment) and index generation thereof) is notified to the call processing process.

Next, the call processing process receiving the message that the new shared memory segment (second segment) has been created uses the voice resources stored in the new shared memory segment (second segment) thereafter (S17).

Of course, the voice output maintained before receiving the message that the new shared memory segment (second segment) has been created uses the voice resource existing in the previously created shared memory segment (first segment) as it is.

That is, the voice output maintained before the change of the voice resource continues to use the previous voice file until the end of the output, and the voices output after the change of the voice resource are read out from the new shared memory segment (second segment) ( S19).

In other words, one call processing process is able to access two shared memory segments (first segment, second segment).

In addition, the manager determines whether the voice resource output of the call processing processes is a new shared memory segment (second segment) or an existing shared memory segment (first segment), and then, for the entire time slots that one call processing process is responsible for, If it is recognized that the existing shared memory segment (first segment) is no longer used (S18), a message is sent to the call processing process to remove the existing shared memory segment (first segment) from the process area.

Accordingly, the call processing process receiving the message to remove the existing shared memory segment (first segment) from the manager removes the existing shared memory segment (first segment) from its process area (S20).

Next, after confirming that all call processing processes have removed the existing shared memory segment (first segment) from their process area, the manager requests the operating system (OS) to completely remove the existing shared memory segment (first segment) (S21). ).

If the request was successfully accepted, there is now only one shared memory segment for voice resources in the system, whereby service continues to be performed (S22).

After that, if a change request of voice resources is newly received, the process may be repeated.

However, if a large number of voice resource change requests are received during the operation, the manager stores the change requests in a stack register (not shown) provided in the system, and when the change operation can be performed, the stack register ( The voice resources are replaced by repeating the above-described process in the order stored in FIG.

At this time, the change request stored in the stack register (not shown) is only valid.

That is, the voice mailing system according to the present invention does not interrupt the mailing service even when voice resources are replaced by redundantly operating the shared memory.

As described above, the voice resource replacement method of the voice mailing system of the present invention does not stop the operation of the voice mailing system when voice resources are replaced, thereby improving the reliability of the user.
