The present invention relates to a voice mail management method in a voice mail apparatus, and more particularly, to a voice mail sharing method of a voice mail apparatus in which a plurality of subscribers can share a voice mail by a logical method. .

In general, if more than one subscriber owns a voice mail, each subscriber has one mail assigned to him. That is, two or more identical voice mails exist on the actual memory, and the voice mails are copied and forwarded directly to the other party.

However, the conventional method requires a lot of memory in the system to allow many subscribers to share a single voice. To solve this problem, if the memory capacity is not increased, the service cannot be received by receiving a lot of other mails, and it takes a long time to copy voice data.

Therefore, an object of the present invention is to share a plurality of subscribers in a logical manner by real-time voice mail by TRN sharing in a voice mail management system when one voice mail recorded once in a voice mail apparatus needs to be shared among a large number of persons due to the characteristics of a service. It provides a way to share the memory and improve the system's memory savings and functions.

The present invention for performing the above object is composed of a profile representing a subscriber, a mailbox pointing to the mails, voice mail indexed from each mailbox (hereinafter referred to as TRN), and a predetermined unit of voice cells indexed from the TRN It features.

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

FIG. 1 is a system block diagram according to the present invention, and is connected to a subscriber interface (Line Interface Unit (hereinafter referred to as LIU) 10) that matches a notary network or a telephone network, and is connected to the LIU 10 to compress general voice data. A voice compression reproducing unit (VCU) 20 for reducing the amount of information or reproducing compressed voice information, and a central processing unit (hereinafter referred to as a CPU) for controlling the system ( 30, a memory 40 for storing programs and voice information for controlling the CPU 30, a hard disk unit 60 for storing processed voice data, and the CPU 30 of the CPU 30. And a disk controller 50 for generating data write and read control signals to the hard disk unit 60 according to the instructions.

2 is a management table constituting the present invention, wherein a voice mail management system of a voice mail apparatus comprises a profile, a mailbox, a TRN (TRANSACTION), a voice cell, and the like.

The voice mail refers to a message of a voice recorded by the user and corresponds 1: 1 with the TRN (TRANSACTION) 400. The voice cell 500 refers to a memory having a predetermined size in the hard disk unit 60 in which recorded voices are stored. That is, the voice mail may be stored in several voice cells displayed on the TRN 400. One voice mail is composed of a combination of voice cells of a certain size because the processing of multiple channels in real time and the size of the digitalized voice data are very large.

In order to maintain the quality of voice and to digitalize the analog signal, 1 second voice of PCM method requires about 8K bytes and ADPCM method requires about 4K bytes. When such a large amount of data is required simultaneously in a plurality of channels (recording or listening), the processing capacity of the hard disk unit 60 storing the actual data determines the system's capability.

If the time taken to read the d-byte data corresponding to the voice T seconds from the hard disk unit 60 (HARD DISK SEEK TIME + DATA TRANSFER TIME) is t seconds, in order to process n channels simultaneously in real time, n The condition of X t ≤ T must be satisfied. Direct access of the hard disk unit 60 using the voice cell index recorded in the TRN 400 and dividing the voice cell 500 into a size that satisfies this condition is more efficient than file access for voice mail management.

The TRN 400 maintains information such as recorded date and time, voice mail type, and the like, including the indexes for these voice cells to form one voice mail. The TRN 400 is classified according to a personality and belongs to a mailbox. The mailbox 300 is an index table for voicemail that allows one voicemail TRN to be logically shared with multiple users.

The voice mail subscriber will access his mailbox using the mailbox number assigned to him. Also, in the voice mail system, full service is performed using the mailbox number. The voice mail management system has one mailbox profile 200 per 100 such mailbox numbers. The profile 200 stores various information related to a mailbox such as a mailbox number, a mailbox type, a user name, a service grade, a user telephone number, a mailbox number, and constitutes the most basic database in a service of a voice mail apparatus.

The profile 200 has an index for the mailbox 300 which stores and stores a predetermined number of voice mails according to a use purpose (for example, for receiving, sending, and MEMO). While the previous TRN 400 holds the actual data for the voice mail, the mailbox holds some additional information about the voicemail service, including the index for the TRN, to connect between the profile and the TRN.

In other words, when one voicemail needs to be delivered to multiple subscribers, such as message broadcasting, message switching, etc. among the episodic functions of voicemail device, only one TRN actually exists, but the index of the corresponding TRN in the mailboxes of multiple subscribers exists. At the same time, the TRN has an S-NO field (which indicates the share of TRN) indicating how many mailboxes it belongs to, so that it can be used as if each have separate voice mails.

3 is a flowchart for carrying out the present invention.

The voice mail management system is largely composed of a profile representing a subscriber, a mailbox indicating mails, a voice mail indexed from each mailbox (TRN; expressed as TRANSACTION), and a unit of voice cells indexed in the TRN. These are done as in FIG. 2 in a system like FIG.

The voice mailbox subscriber has one profile, and the profile has a plurality of mailboxes and data determined according to the characteristics of the mailbox subscriber.

The mailbox has an area for storing a predetermined number of voice mail related data, and if there is a mail, it has an index (for TRN) for the mail. The TRN has an index for the voice cell in which the actual voice is recorded. The present invention has the structure shown in FIG. 4 and can logically share the actual one message according to the flowchart of FIG.

Voice Mailing System (VMS) works in conjunction with an electronic exchange or alone to digitalize voice, an analog signal, to store it on the hard disk and play it back, so that voice mail function, advertisement recording listening, missed message reception, It is a system that functions to receive a message during a call, broadcast a message, and switch a message. In order to realize these functions, a voice mail management system that systematically manages digitalized voice data like data used in a general computer is required.

However, digitalized voice data is fundamentally different from general data, and due to its feature that needs to be processed in real time, it is inherently different from the file management system (FMS) of general computers. You need a voice mail management system.

Therefore, when a specific embodiment of the present invention is described in detail with reference to FIGS. 1 to 4, in step (1), when a user accesses the system for the purpose of recording or listening to a voice mail, the user selects a function. The input is known to the CPU 30 through the LIU 10 and analyzed. In step (2), it is checked whether the user wants to record. If recording is desired-that is, a new TRN is created-in step (3), the voice mail management system on the memory 40 finds an empty TRN to be recorded in the voice mail management system under the control of the CPU 30. When a new TRN is created, the S-NO is initially set to 1 in step (4).

In step (5), the real voice is controlled by the CPU 30, and the disk controller 50 stores the voice in the voice cell of the hard disk 60. When recording is completed, the disk controller 50 controls the control of the CPU 30 in step (6). Accordingly, the position of the TRN found in step (3) is written in the user maylax in the voice mail management system on the memory 40. Initially only one L1 link will be created. After a message is recorded as above, the user may need to copy the message as the user switches and notifies the message to another user. That is, if the user input of step (1) requires copying, steps (8) and (9) are performed through step (7). In step (8), the number of users possessing the corresponding TRN increases by one, so that the S-NO indicated is increased by one. In step (9), the mailbox connects the TRN and the mailbox by writing the location of the TRN to the TRN index. That is, a link such as L2-Ln is formed.

When a user wants to delete a message, the user who owns the corresponding TRN is reduced by the deletion in steps (1) and (10) and in step (11).

In step 12, the TRN is disconnected from the mailbox by clearing the TRN index of the mailbox. That is, one link such as L2-Ln is reduced. In step (13), it is checked whether S-NO is 0. If it is 0, it indicates that no user owns the TRN. In step (14), the voice cells connected to the TRN and the TRN are cleared.

As described above, by allowing a single message to be shared to a plurality of users as logically several, there is an advantage of not only saving memory but also reducing the time required for copying and improving the processing power of the system.
