The present invention relates to an announcement broadcasting service apparatus of an electronic switch.

A typical electronic switchboard is an Access Switching Subsystem (hereinafter referred to as ASS) that performs distributed call processing according to the configuration location of physical resources, and an Interconnection Network Subsystem that performs ASS interconnection exchange function. ), Three subsystems of the Central Control Subsystem for centralized operation and maintenance functions, a Remote Access Switching Module to accommodate remote subscribers, and a small Remote Access Switching Sub It consists of two modules of the system (Small RASM).

Among them, ASS is equipped with subscriber and trunk line interface, time switch link, signal and announcement broadcasting service device, packet handler, test device, etc. to perform most call processing functions and operation and maintenance functions.

In particular, in order to increase the modularity and improve the reliability of the electronic switchboard, each subsystem adopts a redundant processor structure by a general purpose 32-bit microprocessor. The control function is implemented in a control hierarchy structure of two levels, a main processor (hereinafter referred to as MP) and a lower processor (hereinafter referred to as TP). The MP, called the main processor, performs higher functional tasks such as call processing, number translation, exchange control, system maintenance and operation. Called a call processor processor, the TP performs tasks that require real-time processing of lower layers such as call line detection, analysis, and signal processing.

On the other hand, the switchboard broadcasts a message related to a special service at the request of a subscriber and a message for informing the caller of a failure state of a call connection occurring during call processing through the announcement service service of the ASS. Such announcement service is various, such as announcement for subscriber service, announcement by call restriction by subscriber service level, announcement for system status, and the like.

In general, the announcement service is classified into fixed and editable announcement broadcasts according to the configuration of voice data. Fixed announcements, for example, "The service is not available right now." Send a fixed voice message. Editing announcements, on the other hand, are a combination of several announcement messages ("hello" + "… service" + "please enter the desired number") and service a voice message with a variable field. That is, an editable voice message including a variable field is transmitted.

1 is a block diagram showing a guide broadcasting service apparatus of an electronic switch according to the prior art.

Referring to FIG. 1, the conventional announcement service apparatus 1 of the electronic switchboard includes a local bus interface memory 12, a controller 14, a guide broadcast transmitter 16, a fixed message memory 18, and an editable message memory. It consists of 20 services fixed announcements (Fixed Announcement) and edited announcements (Mixed Announcement) services.

The local bus interface memory 12 receives channel information, message information, message number, etc. of each call from the MP (not shown), and transmits the announcement when the announcement is transmitted as many times as the number of repetitions or when the termination command is received from the MP. Send information to end.

The controller 14 periodically scans the local bus interface memory 12 for matching with the higher processor and receives a guide broadcast transmission command including channel information, message information, and message number provided from the MP. The controller 14 analyzes the received command to select a fixed or edited announcement broadcast sequence (ANM1, ANM2, ANM3, ANM4…) and finds a fixed message or edited message number corresponding to the selected sequence and broadcasts the corresponding announcement. Control to send a message. The control unit 14 also stores the announcement broadcast transmission sequences ANM1, ANM2, ANM3, ANM4, ... in an internal memory (e.g., ROM). In addition, the controller 14 transmits the transmitted announcement result to the MP.

The announcement broadcasting unit 16 accesses each recorded voice message of the fixed message memory 18 and the editable message memory 20 according to the control signal of the control unit 14 to determine PCM voice data and test patterns designated for each call channel. Send data and the like.

The fixed message memory 18 stores a plurality of fixed voice messages FIX0, FIX1, FIX2, FIX3, FIX4... Which are stored by the identification number ID. For example, the fixed message memory 18 may use a flash memory that can be rewritten.

In addition, the editable message memory 20 includes editable voice messages (MIX0, MIX1, MIX2, and MIX3) that combine a plurality of announcements with a message including variable fields such as integers, numbers, dates, times, and amounts for each memory area. , MIX4, MIX5 ...) are stored and the stored voice messages are identified by identification numbers. For example, most of ROMs are used as the editable message memory 20.

The announcement service apparatus 1 of the prior art electronic switchboard (TDX-100) configured as described above is fixed type such as channel information, message information, and message number provided from the MP through the local bus interface memory 12, or When the edited message selection information is received and transmitted to the controller 14, the controller 14 analyzes whether the received information is a fixed or edited message. Then, the fixed or editable announcement broadcast sequence is selected according to the selected message type. The announcement broadcaster 16 is a fixed message in the fixed message memory 18 or the editable message memory 20 according to a control signal of the control unit 14 (a signal for controlling a fixed or edited message to be output according to the selected sequence). Or find an editable message ID to service announcements. Then, the controller 14 transmits the announcement result transmitted through the local bus interface memory 12 to the MP, and transmits information for terminating the announcement broadcast transmission function when the instruction to terminate the announcement service is received from the MP. .

However, the electronic switch according to the prior art as described above can be rewritten in the case of a fixed message when the announcement message (fixed or editable) is to be changed in the announcement service apparatus 1, but in the case of an editable message, New memory must be replaced. In this manner, when the announcement message is changed, a new announcement broadcast sequence must be created in accordance with the newly changed message in the memory built into the controller 14. However, since the control unit 14 adopts a ROM which cannot be rewritten into the internal memory, it is impossible to newly change the announcement broadcast transmission sequence according to the changed announcement message. Therefore, in order to change the announcement broadcast transmission sequence, it is necessary to replace the memory with the new sequence recorded.

Therefore, when changing the announcement message in the conventional electronic switchboard, the announcement broadcast sequence must also be changed according to the changed message memory information. Accordingly, when the announcement message is changed, the number of memories recording the announcement broadcast transmission sequence of the exchange to be replaced each time becomes large, so that a measure for reducing waste of resources is needed.

The controller 120 receives a guide broadcast transmission command including channel information of each call provided by the MP and a guide broadcast message number (MSG ID) through the local bus interface memory 110. The controller 120 analyzes the received command and reads the announcement broadcast sending sequence (a sequence for sending a fixed or edited message) of the announcement broadcasting memory 130 to the message memory 150 corresponding to the read sequence. The announcement broadcast message is controlled by controlling the announcement broadcasting unit 140 to select the fixed message or the editable announcement message number. In addition, the controller 120 records the processing result of selecting the message number in the local bus interface memory 110 according to the announcement broadcast transmission sequence read from the announcement broadcast sequence memory 130 and rewrites the announcement announcement result sent to the local bus interface memory 110. Transmit to 110 via MP.

In particular, the controller 120 of the present invention receives the information on the announcement message (fixed or edited voice data) transmitted from the MP through the local bus interface memory 110 at the time of system initialization, and receives the received information from the announcement sequence. It is possible to store in the memory 130. In addition, the controller 120 of the present invention controls the announcement broadcast transmitter 140 to select a corresponding announcement message number when a command for recording a new announcement message is received in the message memory 150.

Announcement sequence memory 130 is an announcement broadcast sequence (ANM1, ANM2) which has assigned at least one announcement message number (MSG0, MSG1, MSG2, MSG3, MSG4…) in order to send the announcement message to the channel formed call; , ANM3, ANM4 ...) are stored, and re-recording of the announcement broadcast sequence is possible. Preferably, the announcement sequence memory 130 may be configured as RAM (eg, NVSRAM).

In addition, the announcement message memory 150 may rewrite both the fixed and editable announcement messages using the flash memory.

In order to perform the announcement service function, the announcement broadcasting service apparatus 100 of the electronic switchboard according to the present invention configured as described above first sends the announcement message message data (fixed or editable PCM voice data) to the message memory 150. Must be recorded in Accordingly, the controller 120 periodically scans the local bus interface memory 110 and stores the transmitted announcement message data in the message memory 150 when a loading command of the message voice data is received.

Meanwhile, the announcement service apparatus 100 may set the local bus interface memory 110 when the system is initialized in order to set or change the announcement broadcast transmission sequence according to the announcement broadcast message stored in the message memory 150 that is already recorded or newly changed. Information about each of the fixed and editable announcement messages stored in the message memory 150 is received from the MP. The received information includes a message number (ID), a message length, a variable field type, etc., related to the area of the message memory 150 in which the announcement message is stored.

Then, the controller 120 classifies the received announcement message information by MSG ID and stores the announcement information in the announcement sequence memory 130.

After the initialization process is completed, the announcement service apparatus 100 periodically scans the local bus interface memory 110 for matching with the MP and receives a announcement announcement command for servicing a desired announcement broadcast on a call in which a channel is formed. Check if it is.

The controller 120 receives information (ie, MSG ID) stored in the announcement sequence memory 130 according to the received channel information and the message number when receiving the announcement announcement command including the channel information and the message number provided from the MP. Select and lead the announcement broadcast sequence based on the basis.
