Description

Method of operating information broadcast service management for a digital subscriber in the digital switching system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of managing various services for digital subscribers, and more particularly, to a method of operating an electronic switchboard for managing an announcement service for digital subscribers.

Announcement function is a service that is already provided in the public switched telephone network (PSTN) and commercialized technology, whereas now, due to the development of communication technology, the existing network is absorbed (integrated) into a single network. The plan to build the system is being promoted worldwide under the proposition of Integrated Services Digital Network (ISDN) and is expected to be commercialized in the next few years.

In line with this trend, the guidance broadcasting function provided by the existing public switched telephone network should also be provided by the integrated telecommunication network, and the interworking with the functions provided by the existing public switched telephone network at the network evolution stage is also required.

As described above, the conventional guide broadcasting function used only in the analog environment was implemented in the digital environment of the electronic switchboard to provide the guide broadcasting service to the digital subscriber, and service interworking with the existing public switched telephone network was also realized.

On the other hand, in devices with centralized control functions, such as electronic switchboards, failures have a significant impact on the quality of communication services. Therefore, maintenance for failure handling services such as diagnosis, discovery, and repair of failures in each system of all electronic switchboards is possible. Only when the maintenance system was maintained, stable operation of the electronic changer could be guaranteed.

Accordingly, the present invention provides the digital subscriber of the electronic switchboard by allowing the operator to easily and accurately manage the announcement system (source that enables the provision of the announcement service) and the designated route for the announcement. The purpose of the present invention is to provide a method of operating an electronic switchboard for managing the announcement service for digital subscribers, which can improve the quality of the announcement service.

In order to achieve the above object, the operation method of the electronic switch for managing the announcement service for the digital subscriber according to the present invention is a digital control of the electronic switch provided with a Central Control Subsystem (CSS) and an Access Switching Subsystem (ASS). In the various service management methods for subscribers, the first step of obtaining the information on the subscriber line designated by the operator and occupying the corresponding path when the operator designates a guide broadcast designation path setting instruction including the announcement test section information by the operator. And a second step in which the operator phone (digital subscriber terminal) transmits a ring after the first step to inform the operator that the designated path for the announcement is configured, and the operator phone hooks off after the second step. If off, all announcements belonging to the test interval specified by the operator are routed from the announcement device. According to the third step of transmitting the operator's phone to the operator in turn and reporting the result to the operator. If the operator's phone is hooked on after the third step, the connection of the designated path to the announcement is disconnected. Characterized in that the fourth step of reporting to the operator.

3A and 3B are flowcharts illustrating an operation process of an electronic switch for managing an announcement service for a digital subscriber according to an embodiment of the present invention.

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

FIG. 1 is a hardware structure diagram of an electronic switching system to which the present invention is applied, and is largely composed of three subsystems of an access switching subsystem (ASS), an interconnection network subsystem (INS), and a central control subsystem (CCS). ASS performs distributed call processing functions, INS performs centralized call processing functions, and CCS is responsible for centralized operation and maintenance functions.

The function of each subsystem is described in more detail as follows.

Since ASS performs most call processing and self-operation maintenance functions, it has a horizontally distributed structure and up to 63 ASSs can be connected to INS. The transmission medium with the INS is an optical fiber link and is also called a data link. In addition, an ISDN digital subscriber interface, an SS No. 7 signaling device, a packet processor function, and a network interworking device function are provided to enable the exchange function in the ISDN.

In addition, ASS exists in one function but at the application stage, ASS-S (analog subscriber), ASS-I (digital subscriber), ASS-T (trunk), ASS-7 (trunk No. 7), ASS-P (packet) It can be classified into the back, etc. In addition, various combinations of the above four forms are possible.

The INS is located at the center of the system and performs the function of connecting ASS to each other or between ASS and CCS. The switch network has a T-S-T switch structure, in which the space switch S is located at INS and the time switch T is located at ASS. Among the call processing functions, it performs centralized functions such as number translation, route control function, and space switch connection, and is also in charge of generating and distributing system clock with network synchronizer.

CCS is a sub-system for overall operational preservation. It is responsible for system operation, test and measurement, statistics and mass storage management, various input / output device control, and data channel connection with other systems.

In the electronic switching system having the hardware structure as described above, targets that enable the management of announcement service for digital subscribers are ASS (especially, ASS-I) and CCS.

That is, in order to implement the management of the announcement service for the digital subscriber of the electronic switchboard, various software blocks are provided in the access switching processor (ASP) of the ASS and the operation and maintenance processor (OMP) of the CCS as shown in FIG. It is provided.

More specifically, the ASS ASP includes a Call Trace & Path Set-up (CTPS) block, a Digital Circuit Control (DCC) block, a Global Service Control (GSC) block, and a Digital Subscriber Interface (DSI) block. An Execution Control (EC) block, a Call Trace & Path Set-up Management (CTPM) block, and an Output Control (OC) block are provided.

The DSI block is connected to an ISDN phone (I-Phone), which is a digital subscriber station, via a network terminating equipment (NTE).

The CTPS block is a building block for call tracking and designation path, the DCC block is a call processing block for digital subscribers, the GSC block is a joint service control block for controlling announcement broadcasting equipment, and the DSI block is an ISDN subscriber matching block. to be.

The EC block is a command execution control block for receiving an operator's command. The CTPM block is a call tracking and designated path configuration management block that requests the execution of a function and is notified of the result and outputs it. The OC block is an output control block.

The process of managing the announcement service for the digital subscriber using the software blocks of the electronic switch as above will be described with reference to the flowcharts shown in FIGS. 3A and 3B.

First, when the EC block provided in the OMP receives a guide broadcast designation path setting command including guide broadcast test section information from the operator, the EC block sends a request guide signal configuration request signal to the CTPM block.

The CTPM block determines whether the subscriber line designated by the operator is an analog subscriber or a digital subscriber when receiving the guide broadcast designation path configuration request signal from the EC block. Sends a signal to create a process that is responsible for configuring a specified path.

The CTPS block generates a process that is in charge of the designated path configuration function for the digital subscriber upon receiving the process generation signal from the CTPM block.

At this time, the process created in the CTPS block requests the occupancy of the corresponding path to the DCC block after obtaining the information on the subscriber line designated by the operator, and requests the call setup when the occupancy response of the corresponding path is received from the DCC block. In order to set various information in order to send a signal to the operator ISDN phone (I-Phone) to send a ring to the DSI block,

When the DSI block receives the ring transmission request signal from the CTPS block, the DDN block controls the operator ISDN phone (I-Phone) through the network terminator (NET) so that the ISDN phone (I-Phone) transmits the ring itself. In other words, in the case of analog subscribers, the ring is sent by the exchange, but in the case of digital subscribers, the ISDN phone (I-Phone) sends the ring directly.

Then, when the operator hooks off the ISDN phone (I-Phone) that is ringing, the DSI block detects the hook-off of the ISDN phone (I-Phone) through the network terminator (NET). When the hook-off detection signal is sent to the CTPS block, the CTPS block requests the connection of the announcement broadcast designated by the operator to the GSC block upon receiving the hook-off detection signal from the DSI block.

When the GSC block is required to connect to the announcement broadcast from the CTPS block, the announcement broadcast device (not shown) is controlled to connect the fixed announcement recorded in the announcement device, and as a result (the guidance broadcast connected to the path configuration is guided by some guidance). Transmits whether the message is broadcast or not) as a CTPS block. Therefore, the operator can listen to the announcement selected by the ISDN phone (I-Phone).

In addition, when the CTPS block receives the path configuration and announcement broadcast connection results from the GSC block, the CTPS block transmits a signal informing of the path configuration and announcement announcement results to the CTPM block, and the CTPM block transmits a path configuration and announcement broadcast from the CTPS block. When receiving the connection result signal, the OC block is output to the CRT (Cathode Ray Tube (shown in FIG. 1)) of the operator by using the MMS (Man Machine Subsystem) library to configure the designated path for the announcement and the announcement connection message. Do it.

Thereafter, when the transmission of the announcement is completed, the CTPS block and the GSC block release the connection of the announcement, and then the announcement connection disconnection message is output to the CRT of the operator through the above-described process.

On the other hand, if multiple announcements are selected by the operator, the above-described announcement connection / disconnection and result reporting process are repeated until the last announcement is transmitted to the operator ISDN phone (I-Phone).

When the operator hooks up the ISDN phone (I-Phone) after the transmission of the last announcement among the announcements included in the test interval selected by the operator, the DSI block is connected to the network terminator ( NET) detects the hook-on of the ISDN phone (I-Phone) and sends a hook-on detection signal to the CTPS block, and the CTPS block is guided to the CTPM block when receiving the hook-on detection signal from the DSI block. Sends a path configuration termination signal for releasing a specified path configuration for the.

When the CTPM block receives the path configuration termination signal from the CTPS block, the OC block causes the OC block to output a release message of the designated path configuration for the announcement to the CRT of the operator using the MMS library, and the CTPS block designates the announcement. Terminate the process you just created for path configuration.

As a result, the operator listens to the announcement broadcast through the ISDN phone (I-Phone), and provides the announcement service for the digital subscriber by watching the designated route connection / release and announcement announcement / connection message for the announcement displayed on the CRT. Management is easy and accurate.

As described above, the present invention enables the management of the announcement service for digital subscribers to be easily and accurately performed, thereby improving the announcement service quality of the electronic switchboard for the digital subscriber.
