Description

VOICE MAIL SERVICE METHOD OF FULL-ELECTRONIC TELEPHONE EXCHANGE}

The present invention relates to a voicemail service method in an electronic switchgear, and more particularly, if any subscriber registers certain contents in a voicemail box for another subscriber, the electronic switchgear transfers the registration contents from the electronic switchgear. It relates to a voice mail service method in.

As is well known, since the development of electron exchanger using vacuum tube from around 1939, based on several field experiments and technical experience on semiconductor, in May 1965, the world's first electron exchanger No. 1 The ESS was developed and put into practice by the US ATT, and since then, with the introduction of new technologies, electronic exchanges have continued to develop.

These electronic exchangers use high-speed electronic devices such as transistors and integrated circuits to quickly and accurately connect subscriber's communication paths, facilitate maintenance work, and provide flexibility and reliability to lead a complex information society. As a system capable of providing a variety of services (reliability) and various services, nowadays, the TDX series electronic exchanger is mainly used.

Such electronic switch (TDX-10) is a large-capacity exchanger co-developed by a predetermined exchange producer centering on the Korea Telecommunications Research Institute to cope with the characteristics of various communication networks. It is easy to add new functions based on a modular structure so that it can be economically configured, and decentralization of control functions using 32-bit commercial microprocessor and message communication by high-speed IPC (Inter Processor Communication). In addition, high-speed communication between subsystems by optical fiber links is achieved.

In particular, the electronic switchboard can generally accommodate up to 100,000 subscribers and 60,000 digital trunk lines, a large capacity switch of 26,000 Erlang and 1,200,000 Bush Hour Call Attemps (BHCA). The 8192 time switch and 64 × 64 matrix type space switch take the form of TST (Time Space Time) group switch structure that has the capacity of 64K time slots in both directions. The inter-station signaling method in such all-electronic exchange can be both No.7 common line signaling method recommended by CCITT and R2MFC loop decadic (LD), and North American method with PCM (Pulse Code Modulation) matching degree 1.544 [Mb / s] And 2048 [Mb / s] European methods are available. In addition, the programming language on the soft side adopts the CCITT High Level Language (CHILL), which is the standard of CCITT, and SDL (Specificat) as the design language. ion and Description Language).

Many terminals (i.e., proportional to the number of subscribers) are connected to the conventional electronic switchboard which has such functions to quickly and accurately handle call processing between subscribers. Call waiting function that generates a signal that indicates that the call is in progress when the third party tries to call, missed guidance function that informs you that you are away, and a predetermined voice message (for example, an important event or important message And the like, and then perform a special service function such as a voicemail service function that allows the registration message to be serviced later.

By the way, in the case of the person (A) who owns the terminal with the voicemail service function, if the user registers the contents of the important event or the important schedule, the user can receive the service, but does not own the terminal with the voicemail service function. If you must attend an important event with another person (B) or if you need to attend an important event together, the person (A) can be provided with information on the important event or important event by the terminal equipped with voicemail service function. This may not be a problem, but the other person (B) does not see the memorandum of important events or important events, or forgets the memory, so that the person (A) may be unintentionally injured by not attending or performing the work together. Therefore, to prevent this in advance, for example, the person (B) must Inconvenience such as the need to notify each time by phone.

The reason for the inconvenience is that the existing voice mail service function is not implemented in the conventional electronic switchboard, so that the terminal having the voice mail service function must be owned in order to receive the voice mail service. .

Therefore, the present invention has been made in view of the above-mentioned problems in the related art, and an object thereof is that if a subscriber using an electronic switchboard registers information on an important schedule (for example, a called number, a service start time, and a voice message) in advance, Voicemail service method in all electronic exchanges, which allows any subscriber using electronic exchange to conveniently use voice mailbox service by having voice message registered at the service time is automatically transmitted to incoming subscriber's side through all electronic exchange. In providing.

According to a preferred embodiment of the present invention to achieve the above object, a first process of notifying the type of service by translating a special service code input through the terminal; A second step of requesting a service start time and a called number after recording a message input by the subscriber if the informed service type is a voice mail service; If the voicemail service change code is received before the service start time arrives while the service start time and the called number are updated and stored, and the service start time is checked, the preceding message according to the contents of the change code. And a third step of checking the new service start time after the new update storage for the service start time and the called number is performed; When the service start time is reached, the ring signal is applied according to the state of the called party, and when the called party responds by the ring signal, the registered message is heard and the incoming message is requested to input the service receiving end code. When the service receiving end code by the subscriber is input, the service start time and the called number are updated and stored in a database, and a voice mail service method is provided in the all electronic switch system, which is configured to end the current voice mail service operation.

Preferably, the embodiment of the present invention may further be provided with a process for notifying that the voice mail service is not completed by determining whether the voice mail service has not been normally processed previously.

The message recording operation in the second process is to record a message input through the terminal as the guide message for requesting a message input is notified to the terminal of the subscriber.

In addition, the service start time and the called number input in the third process are updated and stored in the database when the service input end code is input by the subscriber.

Here, the input of the service input termination code may be input as the guide message requesting the input of the service input termination code is notified.

In addition, when the service cancellation code is received while the service start time does not arrive, the voicemail service information finally stored is cancelled.

On the other hand, if the voicemail service change code is received while the service start time has not arrived, the new service start after the new update and storage of the preceding message, the service start time and the called number are performed according to the contents of the change code. Check if time is coming.

If the called party does not respond in the fourth step, it is determined whether the non-response time has elapsed for a predetermined time. If it does not exceed, it is determined whether the incoming subscriber responds again after waiting for a predetermined time, while if the count value exceeds a certain number of times, the voice mail service operation for the corresponding service information is not performed.

In addition, when the called subscriber responds in the fourth process, the message is repeatedly heard for a predetermined number of times until the service receiving end code is received.

According to the embodiment of the present invention configured as described above, if the subscriber registered in the electronic switchboard enters the code for the voicemail service and then inputs the message, the service start time, and the called number, the subscriber inputs the service start time according to the arrival of the service start time. The message is then sent to the called party by the switchboard.

Hereinafter, with reference to the accompanying drawings, an embodiment of a voice mail service method in an electronic switch according to the present invention will be described in more detail.

1 is a software block diagram of an electronic switching system employing the present invention, the embodiment of the present invention is a number translation block 10, subscriber service control block 12, joint service control block 14, analog subscriber Control block 16, real-time operating system 18, database 20, voice message service unit 22, and a terminal 24.

In the figure, the number translation block (NTR) 10 performs station number translation and called party number translation at the request of the subscriber service control block 12, while a special service code (i.e., voice mail box) assumed in the present invention. The service code and voicemail service mode, service cancellation code, service change code, message change code, etc., which are input under the service mode, will be equipped with a translation function.

Here, in the embodiment of the present invention, the voicemail service is provided to the ″ * ″ key, the ″ 9 ″ key, and the ″ 7 ″ key, for example, among the 10-keys installed in the subscriber's terminal (telephone: 24). It is registered by the voicemail service code of ″ * 97 ″ designated by.

The subscriber service control block (SSCO) 12 controls the entire operation of the electronic switchboard so that the operation of the special service can be performed smoothly as any special service is selected by the subscriber.

In addition, the joint service control block (GSC) 14 receives the service information (eg, service start time, called number, etc. for the voicemail service) applied to the analog subscriber control block (ASC: 16). SSCO: 12).

The analog subscriber control block (ASC) 16 performs a terminal device matching function, a signal processing function, a call processing function, a matching function with the subscriber service control block (SSCO) 12, and the like.

The real time operating system (cros) 18 is configured to promptly and accurately perform a fast processing operation (e.g., editing or updating) of information input from the terminal 24 and a necessary information exchange operation in an all-electronic exchange employing the present invention. do.

The database (DB: 20) is a kind of data base for receiving, storing, and supplying data to a plurality of independent subscribers registered in the electronic switchboard in response to their requests. The service start time and the called number according to the voicemail service function assumed in the present invention are stored by the subscriber service control block (SSCO) 12.

The voice message service unit (VMSU: 22) has a function of notifying the relevant subscribers by recording a guide message when a problem occurs in the call processing process due to a station number missing or a number change, and notifying of a missed notice or a designated time. While performing the function of notifying additional subscriber to the recorded message, the message inputted from the subscriber is stored as the voicemail service assumed in the present invention is registered, and the stored message is transmitted to the called party at the time of service start. You will be informed.

Next, a voicemail service method in an electronic switch system according to the present invention based on the device configured as described above will be described with reference to the flowchart of FIG.

First, the subscriber hooks off the terminal (telephone) 24 and inputs a certain special service code (step 100). The inputted special service code is the analog subscriber control block (ASC: 16). Through the subscriber service control block (SSCO: 12).

Accordingly, the subscriber service control block (SSCO: 12) in the number translation block

The special service code is handed over to (NTR: 10) and a translation is requested for the code (step 110).

Then, the number translation block (NTR) 10 executes a translation of the input code (that is, a translation of which special service), and while the code translation is being performed, the subscriber service control block (SSCO) 12) controls the real-time operating system (cros: 18) to determine whether there is a voice mail that has not been normally processed before.

Accordingly, when the code translation in the number translation block (NTR: 10) is notified from the real time operating system (cros: 18) that there is an unprocessed voice mailbox (″ YES ″ in step 120), the subscriber service control is performed. By block SSCO 12, the voice message service unit 22 notifies the subscriber (meaning the subscriber who entered the voicemail service code) that the voicemail box was not processed normally (step 130).

On the contrary, the service type translated in the number translation block (NTR: 10) in the state where it has been found that the voice mail that was not normally processed before (NO in step 120) is stored in the subscriber service control block (SSCO). 12), the subscriber service control block (SSCO) 12 controls to perform a service operation according to the informed service type.

In this case, if the notified service type is a voice mail service (for example, when the special service code is ″ * 97 ″), the subscriber service control block (SSCO) 12 is an analog subscriber control block (ASC: 16). By setting a path between the subscriber and the voice message service unit (VMSU: 22), the voice message service unit (VMSU: 22) informs the user to enter a desired message. In response, the subscriber enters a message through a terminal (phone 24), and the incoming message (i.e. voice message) is stored (recorded) in the voice message service unit (VMSU) 22 (step 150). .

When the recording of the message is completed, the voice message service unit (VMSU) 22 notifies the user of a message for inputting a service start time and a called number (step 160), and in response to the message, the subscriber receives the terminal 24. Using the 10-keys on the top, the service start time (eg, ″ 05251200 ″) and the called number (eg, ″ 0326905742 ″) are entered. Here, in the service start time information, ″ 05 ″ means month, ″ 25 ″ means day, ″ 12 ″ means hour, ″ 00 ″ means minute, and the called number In the information, "032" is the area code, "690" is the station number, and "5742" is the registration number of the called party.

The service start time and the called number input as described above are updated and stored in the database (DB: 20) when a service input end code (for example, ″ * ″) is input (step 170). The end code may be input immediately after the service start time and the incoming number have been input, without a transmission of the guide message for entering the service input end code (in this case, the subscriber knows the service input end code in advance. The voice message service unit 22 may be input in response to a guide message requesting the input of a service input termination code notified by the voice message service unit 22.

Subsequently, when the service start time and the called number are updated and stored, the subscriber service control block (SSCO: 12) releases the path established between the subscriber and the voice message service unit (VMSU: 22), and the real time operating system (cros: 18). ), The real time operating system (cros: 18) checks the service start time stored in the database (DB: 20) (step 180).

Accordingly, in the case where the service start time does not arrive (″ NO ″ in step 190), the subscriber service control block (SSCO: 12) is a service cancellation code or voicemail service change code from the terminal 24 on the subscriber side. If a service cancellation code (e.g. ″ # 98052512000326905742 # ″) is entered (″ YES ″ in step 200), the previously recorded message is canceled and the service for the message is determined. If the start time and the called number are canceled, and the service cancellation code is not entered and the voicemail service change code is entered (″ NO ″ in step 200 and ″ YES ″ in step 210), the contents of the change code are changed. The registered voicemail service information is updated and stored (step 220).

Here, for example, the voicemail service change code is ″ # 98052518000326

In the case of 905742 * ″, the voicemail service start time of the subscriber whose called number is ″ 032-690-5742 ″ has been changed from 12:00 on May 25 to 18:00 on 25 May, and the database ( DB: 20) Voicemail service information stored in

Update the service (ie service start time). On the other hand, if the voicemail service code change code is ″ # 98052512000326901111 * ″, for example, the caller ID number for the message having the voicemail service start time of 12:00 on May 25 is ″ 032.

The voicemail service information (ie, called number) stored in the database (DB: 20) is updated by recognizing that the data has been changed to -690-1111 ″. In addition, when the voicemail service code change code is ″ # 98 ******** 0326905742 * ″, for example, the service information of the called number ″ 032-690-5742 ″ (ie, message, service start) Recognizing that only the message is changed among the time and the called number, the message for requesting the message input request as in step 150 described above is sent and the new message inputted through the terminal 24 is updated and stored in response thereto.

In this way, when the new service is updated and stored and the service start time for the message arrives or the original service start time arrives without any change (″ YES ″ in step 190), the real-time operating system ( cros: 18) informs the subscriber service control block (SSCO: 12) that the registration time (i.e., service start time) has been reached, so that the subscriber service control block (SSCO: 12) is the destination analog subscriber control block (ASC). 16), a call is made to request call setup (step 230).

As a result of the call setup request, if the called party's call status is not idle (″ NO ″ in step 240), the call status is monitored until idle (step 250), and then the called party's call status is monitored. If it is in the idle state (" YES " in step 240), a ring signal is sent to the called party (step 260).

However, if the called party does not answer (i.e., does not hook off the terminal (telephone 24) ("NO" in step 270)), it is determined whether the non-response time has elapsed for a predetermined time (for example, about 5 seconds). If it is determined that the predetermined time has elapsed (″ YES ″ in step 280), the calculated count value is increased by ″ 1 ″ (step 290). Then, if the count exceeds a certain number of times (e.g., three times) ("YES" in step 300), the voicemail service that informs the registration message to the called subscriber is stopped, but the count does not exceed the predetermined number of times. If not (″ NO ″ in step 300), wait for a predetermined time (for example, about 30 minutes) (step 310), and then return to step 230 as described above and call the analog subscriber control block (ASC: 16) on the called side again. Request a setting and repeat the operation afterwards.

On the contrary, when there is a response from the called subscriber in step 270, the subscriber service control block SSCO 12 requests the analog subscriber control block ASC 16 to inform the subscriber and the voice message service unit VMSU 22 ), And the message registered in the voice message service unit (VMSU: 22) is transmitted, so that the message for the called party transmitted from the voice message service unit (VMSU: 22) is called. Through 24, the called party is informed (step 320).

Then, the subscriber service control block (SSCO) 12 determines whether a service receiving end code indicating that a message is received is inputted, and the service receiving end code (for example, ″ * 99 * ″) is inputted. (″ YES ″ in step 330), there are no more message transmissions.

However, when the service receiving end code is not input (″ NO ″ in step 330), call setting is made three times at a predetermined time (for example, about 30 minutes) from the time of first notification (for example, 12:00). Requesting the voice message service unit

The voicemail service message registered in (VMSU: 22) is played (steps 340 to 350).

Here, if the message transmission reaches the predetermined number of times (eg, three times) without the service receiving end code being input, the voicemail service is terminated.

According to the present invention as described above, if the subscriber using the electronic switchboard without having a telephone with a separate voice mail service function, the voice mail service can be used as much as possible using a special service. There is an advantage to maximize the use efficiency of the electron exchanger.

In addition, this invention is not limited only to the above-mentioned embodiment, It can implement by modifying and modifying within the range which does not deviate from the summary of this invention.
