Description

VOICE MAIL SERVICE METHOD FOR FULL ELECTRONIC EXCHANGE}

The present invention relates to a voice mailbox service method for each group of an electronic switchgear, and more particularly, when the electronic switch exchange sends a pre-registered voice mail message to a subscriber of a group assigned to a predetermined subscriber. The present invention relates to a method for group voicemail service of an electronic switchboard which enables a subscriber to retrieve an unresponsive answer to a voicemail message in a group and to notify a subscriber of the voicemail message to a registered subscriber.

As is well known, the electronic exchanger employs electronic devices capable of high-speed operation such as transistors and integrated circuits to quickly and accurately connect the subscriber's communication paths, facilitate maintenance work, and provide flexibility to lead a complex information society. It is used as a system that can provide flexibility, reliability, and various services.

Such switchboards (such as TDX-10) can cope with the characteristics of various communication networks, and can easily add new functions based on a modular structure so that they can be economically configured from the small scale of farming and fishing village to the large scale of large city. In addition, distributed control functions using 32-bit commercial microprocessors and message communication by high-speed IPC (Inter-Processor Communication) are enabled, and high-speed communication between subsystems is achieved by optical fiber links. .

In addition, these electronic switchboards can generally accommodate up to 100,000 subscribers and 60,000 digital trunk lines, 26,000 Erlang bulk switches and 1,200,000 Bush Hour Call Attemps (BHCA). It takes distributed control method that can handle)), and 8192 time switch and 64 × 64 matrix type space switch take TST (Time-Space-Time) type group switch structure with 64K time slots in both directions. F. The inter-station signaling in such an electronic switchboard can be both No.7 common line signaling and R2MFC LD (Loop decadic) recommended by CCITT, and the PCM (Pulse Code Modulation) of 1.544 [Mb / s] In addition to the North American method and the European method of 2048 [Mb / s], the programming language on the soft side adopts the high-level language CHILL (CCITT High Level Language), the standard of CCITT, and SDL (Specif) as the design language. ication and Description Language).

With such functions, a number of terminals (ie, proportional to the number of subscribers) are connected to a general electronic switch that handles call processing between subscribers quickly and accurately. Call Waiting function that generates a signal indicating that the user is busy when the user attempts to make a phone call, missed guidance function that informs that other subscribers are away, and registers a predetermined voice message in advance, and then registers the voice message later. Special service functions such as voicemail service function to allow service can be performed.

In this voicemail service function, any subscriber can classify a plurality of subscribers who are expected to have frequent calls with each other by a plurality of groups, and register different voicemail messages for subscribers of each classified group. In addition, by specifying a group by manipulating a number key and a special key provided in the telephone, a group voice mail service function is adopted, which allows the subscribers of the group to simultaneously register a voice mail message.

However, in the voicemail service function of each group in the electronic switchboard, when a voicemail message registered at a time is sent to a predetermined group subscriber assigned to a certain subscriber, a predetermined subscriber is absent among the subscribers in the group. Even if the voicemail message sent out due to the call function or the call function with other subscribers is not received, the registered subscriber who registered the voicemail message cannot easily recognize this fact. The disadvantage is that it becomes difficult to implement.

Accordingly, the present invention has been made in view of the above-mentioned disadvantages, and enables a voicemail message to be registered for each of a plurality of subscriber groups assigned by a predetermined subscriber in an electronic switchboard, and the voicemail message is a subscriber for each group. The purpose of the present invention is to provide a voicemail service method for each group of electronic switchboards, which makes a list of non-responsive subscribers to be notified to registered subscribers of voicemail messages when they are sent.

In order to achieve the above object, according to the voice mailbox service method for each group of the electronic switchboard according to the present invention, a plurality of subscribers are classified into a plurality of groups for a random subscriber, and the registration and transmission of voice mailbox messages for each group are performed. In the electronic switchboard having a voicemail service function, a subscriber group for predetermined subscribers to which a voicemail message and a service start time of the message are registered by the subscriber, and a registered voicemail message is sent. A first step of designating, a second step of requesting call setup for subscribers of the designated group when the service start time for the registered voice mail message has elapsed, and the voice mail message according to the call setup request. The call setup request time for subscribers by designated group has elapsed. A third step of extracting an unresponsive state for the subscribers in the group who do not respond to the group and creating a search list; and a fourth step of notifying the registered subscriber who registered the voicemail message with the search list for the retrieved unresponsive subscriber. And a fifth step of resending to the non-receiving subscriber of the search list according to the passage of the service start time when the corresponding voice mailbox message is renewed by the resend code input of the registered subscriber and the update input for the service start time. Provides voice mailbox service method by group of electronic switchboard.

Preferably, the search list created for the unresponsive subscriber to the voicemail message in step 4 allows the registered subscriber of the voicemail message to be notified by inputting a confirmation code for sending the message.

In addition, if the service start time of the corresponding voice mailbox message is not renewed when the resubmitting code of the registered subscriber is input, the voice mailbox message may be resent to unsubscribed subscribers as the service start time specified in the first step elapses. Characterized in that made.

According to the present invention configured as described above, in the electronic switchboard, a plurality of subscribers who are expected to talk to a predetermined subscriber can be classified into a plurality of groups so that different voicemail messages can be sent for each group. When sending a registered voicemail message to a subscriber in a group, unanswered subscribers for the voicemail message are searched out so that a list of unanswered subscribers can be notified at the request of a registered subscriber of a message later. have.

In other words, Fig. 1 is a block diagram showing the software block configuration of an electronic switching system employing the method of the present invention. In the figure, reference numeral 2 denotes a station number translation and destination number upon request of a subscriber service control block 4 described later. A voicemail service code, a selection code for selecting a group classified for a plurality of subscribers, a confirmation code for identifying unsent subscribers of a registered voicemail message, and a voicemail service mode, A number translation block (NTR) having a translation function for a special service code related to a voice mail service function such as a service cancellation code, a service change code, and a message change code.

Further, reference numeral 4 denotes a predetermined subscriber (e.g., a first subscriber) by the voicemail service function as a special service such as a voicemail service function is selected by a plurality of subscribers according to the first to nth telephones A1 to An. The subscribers of the second to nth telephones A2 to An allocated mainly to the subscribers of the telephones A1 can transmit the voicemail messages smoothly to the subscribers of each group designated by the plurality of groups. In addition to controlling the overall operation of the exchange, the subscriber service control block (SSCO), which is responsible for the overall control of the retrieval and retransmission of subscribers who have not responded to the voicemail message among the group-specific subscribers designated as the sending targets of the voicemail message, Indicates.

Here, the subscriber service control block 4 is a subscriber of the second to the n-th telephone (A2 ~ An) that is expected to talk to any subscriber (for example, the subscriber of the first telephone (A1)). That is, by classifying and designating into a plurality of subscriber groups at the request of the first telephone A1, the voice message service unit 14 to be described later is processed, and the random subscriber (first telephone ( The voicemail message recorded by the subscriber of A1) is stored in the database 12 described later to correspond to the designated subscriber group.

In addition, the subscriber service control block 4 transmits the voice mailbox message recorded by the elapsed service start time of the voice mailbox service according to the request for the delivery of the individual voice mailbox message to the group subscribers assigned by any subscriber. The call setup request is made to the subscribers of the corresponding group as much as possible, and the database 12, which will be described later, is retrieved by retrieving the unanswered subscribers (i.e., no incoming or busy) until the predetermined time elapses from the call setup request. A confirmation code for creating a search list based on the information and confirming whether or not a voicemail message is sent to an unanswered subscriber by any subscriber (subscriber of the first telephone A1) that registered the voicemail message is provided. When inputted, the created search list is controlled so that voice can be sent to any subscriber side as a guide message. .

The subscriber service control block 4 retransmits the voice mail message recorded to the unanswered subscriber's voice mail message corresponding to the created search list according to the input of the retransmission code by the random subscriber. When the function is executed, the service start time of the renewal inputted message by the subscriber is started so that the voicemail message can be sent out to the non-responders in the designated group as the start time passes. If the service start time is not renewed while the resend code is input by the subscriber, the voice mail message is controlled to be transmitted according to the passage of the service start time previously input.

Also, reference numeral 6 notifies the subscriber service control block (SSCO) 4 of the service start time, group number, and called number for the voicemail service applied to the analog subscriber control block (ASC) 8 described later. Represents a common service control block (GSC).

Reference numeral 8 denotes an analog subscriber control block (ASC) that performs a matching function with the terminal 16, a signal processing function, a call processing function, and a matching function with the subscriber service control block 4, and the like.

Also, reference numeral 10 assists in the rapid processing of the information input from the terminal 16 (e.g., editing or updating) and the quick and accurate processing of the voicemail service function for each group of a plurality of subscribers according to the present invention. Represents a real-time operating system (CROS).

Further, reference numeral 12 denotes a group classification request by subscribers of a plurality of independent first to nth telephones A1 to An registered at the electronic switching center and a request for the execution of the voicemail service function for the classified group subscribers. A database (DB) that acts as a data base for receiving, storing, and supplying data in response to the request, wherein the database 12 includes a service start time and a voice of a message input by executing a voice mail service function according to the present invention. The subscriber group number to which the mailbox message is sent and the search list for unresponsive subscribers of the voice mailbox message are stored by the control of the subscriber service control block (SSCO: 4).

In addition, reference numeral 14 has a function of notifying the corresponding subscriber by recording a message when the storage occurs during the call processing due to a station code number, a change of number, or an additional recording message such as an absence notice or a designated time notification. A voice message service unit (VMSU) for performing a function of informing a corresponding subscriber, wherein the voice message service unit 14 registers and stores a voice mail message by executing a voice mail service function according to the present invention. As the service start time elapses, the stored voicemail message is sent to the called party subscriber in the designated group.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 2.

First, in step 20, a plurality of second to nth telephones A2 to An is required by an arbitrary subscriber (for example, a subscriber of the first telephone A1; hereinafter referred to as a subscriber of the first telephone A1). According to a plurality of groups according to the classification, and the classified information of subscribers classified by the group is stored in the database 12 in the electronic switchboard 100, a special service key by the subscriber of the first telephone (A1) is input Then, the number translation block 2 of the electronic switchboard 100 translates the inputted special service code (step 21).

In this state, in step 22, the subscriber service control block 4 receives the special service code by the subscriber of the first telephone A1 translated by the number translation function of the number translation block 2. If it is determined that the code is an execution code of the voice mail service function for sending the voice mail message to the voice mail message, the voice mail message input from the talker of the first telephone A1 is recorded and stored in the voice message service unit 14, Proceeding to step 23, the database 12 stores the group number and the service start time of the message inputted by the first telephone A1 to which the designated voicemail message is to be sent.

In that state, the process proceeds to step 24 where the subscriber service control block 4 times the service start time specified by the group voicemail service function.

Then, the process proceeds to step 25, where the subscriber service control block 4 determines whether the service start time of the revealed message has elapsed.

As a result of the determination in step 25, if it is determined that the service start time of the timed message is elapsed, the control proceeds to step 26 and the call to the terminal 16 corresponding to the called party group through the analog subscriber control block 8; As a setting request is made, incoming calls are made to the telephone subscribers in the group among the second to nth telephones A2 to An.

In that state, the flow advances to step 27 to determine whether all the subscribers in the called party group respond to the incoming call.

As a result of the determination in step 27, if it is determined that all the subscribers in the called party group respond to the incoming call, then control proceeds to step 28 so that the stored voice mail message is transmitted through the voice message service unit 14.

However, if it is determined in the step 27 that some of the subscribers in the called party group do not respond to the incoming call, then control proceeds to step 29 where a predetermined predetermined time has elapsed in the unresponsive state of the some subscribers. Judge whether

As a result of the determination in step 29, if the subscriber service control block 4 determines that some of the subscribers in the called party group are unresponsive even after a predetermined time elapses, the control proceeds to step 30, where the control is not answered. The subscriber's incoming number is used to make an outgoing operation to create an outgoing list, and the incoming operation is stopped to enter the standby state.

Then, the flow advances to step 31 whether the confirmation code for confirming whether the voicemail message has been sent to all the subscribers in the designated group by the voicemail service function by the subscriber of the first telephone A1 is input. Judge.

If it is determined in step 31 that a confirmation code for confirming whether or not the voicemail message is sent is inputted, then control proceeds to step 32 and the voice message is determined by a search list of unanswered subscribers stored in the database 12. The service unit 14 is activated to send the color search list as a voice message to the first telephone A1 side.

In that state, the flow advances to step 33 to determine whether a resend code for resending of an unsubscribed subscriber of the voicemail message is input.

If it is determined in step 33 that a resend code for resending the voicemail message is being input, then control proceeds to step 34 and the service start time renewed and inputted from the first telephone A1 is indicated. In step 24, the voice mail message stored in the voice message service unit 14 is transmitted to the subscriber in the designated group as the service start time elapses.

At this time, if the service start time is not renewed when the retransmission code is input by the first telephone A1, the service start time is inputted in step 23, and the corresponding service start time elapses. The voicemail message to be sent is made possible.

According to the present invention made as described above, when the number of subscribers assigned to a predetermined subscriber in the electronic switchboard is classified by group, a search list for unresponsive subscribers when a voicemail message is sent for a predetermined subscriber group. A voicemail message is sent to subscribers in the designated group by allowing the subscriber to notify the subscriber of the voicemail message afterwards and to resend the voicemail message to a non-receiving subscriber by re-entering the subscriber. Not only can the registered subscriber accurately determine whether the message has been sent correctly, but the subscriber in the group has an advantage that the voicemail message can be sent as a whole.
