Method and apparatus for mail handle in Voice Mail System

The present invention relates to a message processing apparatus and method of a voice mailbox system, and more particularly, to a message processing apparatus and method of a voice mailbox system for providing a voice mailbox service to a subscriber in real time.

In general, a voice mail system (hereinafter referred to as a VMS) is a private exchange or personal communication system in a situation where the recipient cannot answer a call, such as when he is away, when power is cut off, or while on a call. Communication System (PCS) is a system that receives a call from a cellular switch and stores a voice message in a VMS memory, and then reads a voice message stored in the VMS memory at the request of a receiver.

As shown in FIG. 1, the conventional VMS 10 includes an exchange matching unit 11, a call distribution unit 13, a call processing unit 15, and a memory unit 17. The unit 11 interfaces with the switch 5 which connects the subscriber 1 and the VMS 10, the call distribution unit 13 is in charge of appropriate call distribution, and the call processing unit 15 has a plurality of calls. It consists of a processor to interface with the actual subscriber (1) to proceed with the voice mail service, to access the memory unit 17 directly in accordance with the voice mailbox service to store specific data in the memory unit 17, the memory unit 17 Information such as sound and images are stored.

Hereinafter, an operation process of the conventional VMS will be described.

When the subscriber 1 makes a call to the other subscriber subscribed to the VMS service, when the other subscriber becomes unable to answer the call, the exchange 5 uses the predetermined protocol to establish a connection between the VMS 10 and the subscriber. Connect to the subscriber to receive voice mail service.

At this time, the switch matching unit 11 and the call distribution unit 13 instructs the voice mailbox service to the call processor to proceed with the voice mailbox service, and the call processor receiving the call instruction provides the voice mailbox service to the calling subscriber. . Accordingly, the subscriber leaves voice data, and the call processor stores the voice data left by the subscriber in the memory unit 17.

Then, when the VMS subscriber is present in the coverage area, the notification function of the VMS 10 notifies the arrival of the voice message, and the subscriber can access the VMS 10 to listen to the voice message stored in his or her mailbox. Will be.

As described above, in the conventional VMS, the call processor operates interactively to provide a service to a subscriber in real time. Since the service resource is stored in the memory unit 17, the memory unit 17 is accessed during the mailbox service. Done. Therefore, when a large number of calls occur during the mailbox service, call processors having the same priority access the memory unit 17, so that the call processor requesting the memory access first can provide the subscriber with the service in real time. However, a call processor that is pushed in sequence does not provide a service to a subscriber in real time.

In addition, when a large number of calls are generated, a plurality of call processors access the memory unit 17, which causes a problem that the memory unit 17 is damaged.

The present invention has been made to solve the above-described problem, the message processing apparatus of the VMS to provide a real-time service to the subscribers of the VMS by the call processing unit indirectly accessing the memory through the message processing unit And to provide a method.

The message processing apparatus of the VMS of the present invention for achieving the above object includes a buffer in which a memory access request command is recorded, and analyzes the memory access request command recorded in the buffer and takes a memory access operation according to an analysis result. A message processing unit; It consists of a number of call handlers to interface with actual subscribers and provide voice mail service. When a user wants to access memory, the user writes a memory access request command to the buffer and immediately provides the voice mail service to the subscriber without waiting for a response from the memory. It is provided with a processing part.

On the other hand, the message processing method of the VMS of the present invention comprises the steps of determining whether a memory access request command exists in the buffer; Analyzing the memory access request command in the buffer when the memory access request command exists as a result of the determination; If the memory access request command is a command for accessing the memory to store the newly generated data in the memory as a result of the analysis, the memory access request command is stored in the memory by accessing the memory, and the memory access request command is stored in the memory. In the case of a command for accessing the memory to delete the stored predetermined data, the predetermined data stored in the memory is deleted by accessing the memory, and the memory access request command deletes the predetermined data stored in the memory. In the case of a command for accessing the memory for changing, the method includes accessing the memory to change predetermined data stored in the memory.

Hereinafter, an apparatus and method for processing a message of a VMS according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing the configuration of a VMS according to the present invention. As shown in Fig. 2, the VMS 40 according to the present invention includes a switch matching section 41, a call distribution section 43, a call processing section 45, a memory section 49, and a message processing section ( 47).

In such a configuration, the switch matching section 41 interfaces with the switch 30 connecting the subscriber 20 and the VMS 40, and processes signals between stations of various protocols to the call distribution section 43. Deliver the call message.

The call distribution unit 43 is a main control device that controls the entire VMS 40, and analyzes the call message received from the switch matching unit 41 to perform proper call distribution. That is, it analyzes the subscriber number received from the switch matching unit 41 to analyze which call processor needs to be processed to maintain the call path with the corresponding call processor.

The call processor 45 includes a plurality of call processors to provide connection, maintenance, recovery, and call processing functions according to the commands of the call distributor 43. The call processing unit 45 is composed of a plurality of call processors to interface with the actual subscriber 20 and to send guide words for providing a voice mail service according to the command of the call distribution unit 43, and accumulate digitized voice or images. Performs voice signal processing functions, such as playback. Then, specific data is stored in the memory unit 49 in accordance with the voice mailbox service. When the memory unit 49 is accessed, the memory access request is recorded in a buffer provided in the message processing unit 47 as a series of promised data packets, and the device 49 waits for a response from the memory unit 49. Instead, the next guide word is sent to provide the voice mail service to the subscriber 20.

The memory unit 49 is a mass storage device for storing various kinds of information such as voice and images.

The message processor 47 is dedicated to memory access and has a buffer for temporarily storing memory access commands required by a plurality of call processors in preparation for requesting memory accesses from a plurality of call processors. Once activated, the buffer is constantly monitored. Accordingly, the message processing unit 47 monitors the buffer, and then a predetermined call processor of the call processing unit 45 enters a series of promised data packets into the buffer of the message processing unit 47 to access the memory unit 49. When the memory access request is recorded, the contents recorded in the buffer are searched to determine what operation to perform, and then the memory unit 49 access operation is performed.

3 is a flowchart illustrating a message processing method of a VMS according to the present invention.

First, the message processing unit 47 initializes the buffer with the system driving (S10), and then monitors the buffer provided in the message processing unit 47 and stores the buffer in the corresponding call processor of the call processing unit 45 in the memory unit 49. It is monitored whether or not the memory access request command is recorded as a series of promised data packets in order to access the (). That is, it is determined whether a memory access request instruction exists in the buffer. In the case where the monitoring result of step S12 is that the call processor writes a memory access request command as a series of promised data packets to a buffer provided in the message processing section 47 to access the memory section 49, it is recorded in the buffer. The contents of the memory access request instruction are analyzed (S14). If the memory access request command written in the buffer as a result of the analysis of the memory access request command in step S14 is a command for accessing the memory unit 49 to write newly generated data in the memory unit 49, the memory unit Accesses 49 and writes newly generated data to memory 49 (S16), and stores a memory access request instruction written in a buffer to delete predetermined data stored in memory 49; In the case of an instruction for accessing 49, the memory unit 49 accesses the memory unit 49 to delete predetermined data recorded in the memory unit 49 (S18), and the memory access request command recorded in the buffer is stored in the memory unit ( In the case of a command for accessing the memory unit 49 to change the predetermined data stored in the memory 49, the memory unit 49 is accessed to access predetermined data recorded in the memory unit 49. In step S20, the process proceeds to step S12, where the buffer is searched to see if there is a memory access request instruction to be processed next.

On the other hand, if there is no memory access request command recorded in the buffer by the call processor of the call processing unit 45 as a result of the monitoring in step S12, the message processing unit 47 until the memory access request command is recorded in the buffer by the call processor It enters the standby state (S22).

Hereinafter, an operation process of the VMS according to the present invention will be described.

When the subscriber 20 calls the counterpart subscriber who has subscribed to the VMS service, and the counterpart subscriber is unable to answer the call, the switch 30 uses the predetermined protocol to send the subscriber to the VMS 40. Connect to the subscriber to receive voice mail service.

At this time, the switch matching unit 41 and the call distribution unit 43 instruct the voice mailbox service to the call processor to proceed with the voice mailbox service, and the call processor receiving the call instruction interactively provides the guided voice to the calling subscriber. Voice mailbox service will proceed. Accordingly, the subscriber leaves the voice data, and the call processor writes a memory access request command to the buffer of the message processing unit 47 to store the voice data left by the subscriber in the memory unit 49.

On the other hand, the message processing unit 47 monitors the buffer provided in the message processing unit 47, and if a memory access request command is recorded in the buffer, the memory access request command recorded in the buffer is analyzed and then the memory is determined according to the analysis result. The unit 49 is accessed. For example, if the memory access request command is a command for accessing the memory unit 49 to store voice data left by the subscriber as a result of the analysis of the memory access request command, the message processing unit The memory 47 accesses the memory 49 and stores the voice data left by the subscriber in the memory 49.

The apparatus and method for processing a message of a VMS of the present invention is not limited to the above-described embodiments, and may be variously modified and implemented within the scope of the technical idea of the present invention.

According to the message processing apparatus and method of the VMS of the present invention as described above, the call processing unit continues the voice guidance service to the subscriber after the memory access request to the message processing unit, the memory access is performed by the message processing unit, It is effective to provide services in real time.

In addition, even if a large number of calls are generated, the memory is accessed only by the message processor, thereby minimizing damage to the memory.
