Description

Method of outputting subscriber's information to the information desk in the digital switching system

The present invention relates to a method of outputting information through a guide of an electronic switchgear, and in particular, a specific subscriber belonging to another group as well as specific subscriber information of a group to which the guide belongs through a specific guide. The present invention relates to a method of outputting subscriber information through a guide of an electronic switchgear so as to confirm information of the electronic switch.

In general, electronic switchboards are equipped with packet switching functions and comprehensive information to provide a wider range of voice and non-voice information communication services through matching not only telephones but also video phones, video tex, facsimile, telex, computers, televisions and various private switching networks. ISDN (Integrated Services Digital Network) is being developed to accommodate advanced network functions such as subscriber access functions, value-added service functions, and mobile communication exchange functions.

FIG. 1 is a structural diagram of a general electronic switch, wherein the electronic switch is composed of three sub-systems: an Access Switching Subsystem (ASS), an Interconnection Network Subsystem (INS), and a Central Control Subsystem (CCS).

The ASS includes a subscriber and trunk line interface, a T-switch, an Asynchronous Transfer Mode (ATM) switch, a frame relay handler, an optical subscriber interface, various signaling devices, a packet handler, and the like. It performs call processing function, self operation and maintenance function. The transmission medium with the INS is an optical link, also called a data link. It accommodates ISDN subscriber interface, No.7 signaling device, frame relay handler, packet handler function and PCS (Personal Communication Service), ATM, optical subscriber access device.

In addition, the ASS is ASS-S (Subscriber), ASS-T (Trunk), ASS-S / T (Subscriber / Trunk), ASS-7 (No.7), ASS-P (Packet), ASS -I (ISDN), ASS-ATM, ASS-F (optical subscriber access device), ASS-PCS, ASS-FR (Frame Relay) and the like may be used in combination.

The INS is located at the center of the system and performs a function of connecting ASS to each other or between ASS and CCS. Point-to-point data links between the INS and the ASS provide communication between the INS and each ASS (information exchanged between subscribers or for use within the system). The INS end of the data link is referred to as a space switch data link (SSL), the ASS end is referred to as a time switch link (TSL), and a link exists for a control action between the CCS and the INS. In addition, the switch network is based on the T-S-T switch structure, the space (S) switch is located in the INS, the time switch (T) or ATM switch is accommodated in the ASS.

In addition, the INS performs a centralized function such as a space switch connection among the call processing functions, and has a network synchronizer to generate and distribute a system clock.

The CCS performs the overall operation and maintenance of the system. In addition to system level operation and maintenance, management, and statistical functions, it performs mass storage media (MT, disk) control management, various input / output statement control with the operator, and interworking with other systems.

On the other hand, the switchboard (national exchange) is to group some or all of the subscribers connected to the same switchboard in order to provide the subscribers with various functions that were provided only in the private exchange, and any subscriber in each group Has introduced CENTREX (CENTRalized EXchange), which allows users to call other subscribers in the same group only by extension dialing.

FIG. 2 is a diagram illustrating a connection state between a conventional electronic switch, a reception desk, and a subscriber in which the CENTREX function is introduced. A part or all of the subscribers connected to the same electronic switch are grouped into a plurality of CENTREX groups (A, B). Some of the CENTREX group (B) is arranged up to 10 guides for performing the guide function of the group, the rest of the CENTREX group (A) is not arranged guides. At this time, up to 1000 CENTREX groups may be accommodated in one electro-exchanger, and only a part thereof is illustrated in FIG. 2.

The subscribers in the CENTREX group are divided into several classes, so some subscribers are restricted from calling outside the CENTREX group, and some subscribers cannot receive special services (multiple calls, etc.) in addition to the services basically provided by the CENTREX group. Among them, the guide is a device that provides a variety of services for low-grade subscribers with limited outbound calls.

Therefore, subscribers belonging to the CENTREX group (A), where the guide is not registered, can only call inside the group and cannot connect to the outside.

In addition, the information desk is provided with a terminal equipped with a key panel, a monitor screen, and the like, and the receptionist working at the information desk responds to the inquiries related to the subscriber's telephone number, billing data or other phone calls using the information desk terminal. Provided various services and managed the CENTREX group.

As described above, in the related art, a receptionist communicates with an electronic switchboard through a guide terminal of an information desk where he or she works to inform information of a specific subscriber of the CENTREX group to which he belongs, that is, whether to subscribe to various additional services. By checking through the monitor screen provided in the terminal, he managed the CENTREX group to which he belongs.

However, in the related art, only the information of subscribers joined to the CENTREX group to which the guide belongs, was not able to know the information of subscribers to other CENTREX groups through each guide placed in some CENTREX groups. The CENTREX Group, which does not have a guide, was not able to check the information of the subscribers in the group. Therefore, integrated management of multiple CENTREX Groups was not possible.

The present invention has been made to solve the above problems, the plurality of CENTREX group is integrated into one super group, and the representative guide in the state registered in the specific guide in the specific CENTREX group belonging to the super guide working According to the request of the receptionist, the corresponding subscriber information of each CENTREX group belonging to the super group can be output to the terminal of the representative reception desk, so that multiple groups can be managed efficiently at low cost (reduction of the employment cost of the receptionist and reduction of the installation guide). The purpose of the present invention is to provide a subscriber information output method through a guide of an electronic switchboard.

In order to achieve the above object, the subscriber information output method through the guide of the electronic switchboard according to the present invention is a method of outputting subscriber information through the guide of the electronic switchboard in which part or all of the subscribers are divided into several groups. A first step of: integrating a plurality of groups into one super group, and registering a representative guide to one of the groups belonging to the super group; A second step of determining whether the selected group belongs to the corresponding super group when the information of another group subscriber is requested from the representative information desk; A third step of judging whether the selected subscriber number is the number of subscribers subscribed to the selected group if it belongs to the corresponding super group as a result of the determination of the second step; As a result of the determination of the third step, the fourth step of collecting the corresponding subscriber information and notifying the guide as the number of the subscribers joining the selected group is provided.

In addition, the present invention is a step of notifying the group number setting error message according to the guidance if not belonging to the corresponding super group as a result of the determination of the second step, and if the number of subscribers subscribed to the selected group according to the determination of the third step The step of notifying the subscriber number setting error message is preferably further provided.

Several CENTREX groups (A and B) are grouped into one super group, and representative guides are assigned only to a specific CENTREX group (B) belonging to the super group.

In addition, as described in the prior art, one electronic switchboard could accommodate up to 1000 CENTREX groups, and subscribers belonging to the CENTREX group (A) without information desks could not connect to the outside.

Figure 4 is a block diagram showing the internal configuration of the ASS of the electronic switch for implementing the present invention, the ASS is an Access Switching subsystem Processor (ASP) equipped with an Attendant Console Control (ACC) block, and Digital Subscriber Interface Telephony Processor (TP) block and BRI (Basic Rate Interface) hardware module connected with guide.

The DSI block is a software block that receives information from a BRI hardware module to which a guide is connected, transfers received information to an ASP, which is an upper main processor, and controls a device.

In addition, the DSI block separates the 2B + D signal and data information received from the subscriber into the B channel and the D channel, and transmits the B channel to the time switch, and the D channel transmits the link access procedure on the D- It handles channel protocol and transmits error-free signaling information to ISDN Subscriber Access Processor (ISAP) and has ISDN subscriber line termination.

The ACC block is a guide control software block loaded in an ASP which is a main processor of the ASS. The ACC block performs an interprocessor communication (IPC) communication with the DSI block to process a control message transmitted by the guide.

The guide is connected to an electronic switching system using BRI, an ISDN interface, and its basic call procedure follows the procedures of ISDN Q.921, Q931. The BRI provides a channel capacity of 2B + D to each subscriber. The BRI is allocated a B channel by using a D channel (16 Kbps) to transmit a signaling message necessary for connection, maintenance, and release of a call, and the necessary data using the B channel ( Voice, digital data).

In addition, the guide is provided with a terminal provided with a key panel, a monitor screen, etc. The guide terminal collects and stores the IPC data generated by the electronic switchboard and outputs it to the monitor screen at the request of the guide.

According to an embodiment of the present invention, a process of outputting corresponding subscriber information of each CENTREX group belonging to a super group through the representative guide of the super group will be described with reference to the flowcharts shown in FIGS. 5A and 5B. As follows.

First, when the receptionist working at the representative information desk of the super group operates the key panel provided in the terminal and inputs the CENTREX group subscriber information output command, the information on the CENTREX group subscriber is displayed. An output request message is sent. At this time, the guide may enter the specific CENTREX group number and subscriber number that you want to check the subscriber information with the command.

More specifically, the CENTREX group subscriber information output request message is transmitted to the ACC block of the ASP via the BRI hardware module of the electronic switching center and the DSI block of the TP.

In addition, various types of information about the super group, the CENTREX group, the information desk, the subscriber, and the like are stored in the system of the electronic switchboard.

5A and 5B, the ACC block determines whether to transmit a control message from a specific guide (representative guide of a super group) (S1). If a control message is received, the control message is displayed. It is determined whether the message is a CENTREX group subscriber information output request message (S2).

As a result of the determination in step S2, if the control message is not the CENTREX group subscriber information output request message, the ACC block branches to step S1 after processing the service corresponding to the message (S3). Search the stored information to determine whether the guide is a registered guide (S4).

As a result of the determination in step S4, if the guide is an unregistered guide, the ACC block transmits IPC data to the guide terminal through the DSI block and the BRI hardware module so that the guide unregistered message is displayed on the monitor screen provided in the guide terminal. After step S5, the process branches to step S1, and if it is a registered information desk, it is determined whether the CENTREX group number is present in the CENTREX group subscriber information output request message (S6).

As a result of the determination in step S6, if there is a CENTREX group number, that is, if a specific CENTREX group number is selected by the guide, the ACC block searches for various information stored in the system and checks whether the corresponding CENTREX group number is a CENTREX group number in a preset super group. It is determined (S7).

If the result of the determination in step S7 is not the CENTREX group number in the super group, the ACC block transmits IPC data to the corresponding guide terminal side through the DSI block and the BRI hardware module and sets the CENTREX group number setting error message on the monitor screen provided in the guide terminal. Is displayed (S8), and then branches to step S1.

However, if there is no CENTREX group number as a result of the determination in step S6, that is, a specific CENTREX group number is not selected by the guide, the ACC block acquires the CENTREX group number to which the corresponding guide belongs (S9).

The determination result of step S7 is the CENTREX group number in the super group, or after step S9, the ACC block determines whether the required subscriber number length in the CENTREX group subscriber information output request message is the same as the extension number of the corresponding CENTREX group (S10). It searches the various information stored therein to determine whether the requested subscriber number is the number of subscribers subscribed to the CENTREX group (S11).

As a result of the determination of steps S10 and S11, if the requested subscriber number length is different from the number of extension numbers of the corresponding CENTREX group or the number of the subscribers subscribed to the corresponding CENTREX group, the ACC block is provided through the DSI block and the BRI hardware module. IPC data is transmitted to the terminal to allow the subscriber number setting error message to be displayed on the monitor screen provided in the information desk terminal (S12), and then branches to step S1.

However, if the requested subscriber number length is the same as the extension number of the corresponding CENTREX group and the number of the subscribers subscribed to the CENTREX group, the ACC block determines that the status of the subsystem in which the subscriber is mounted is normal. It is determined (S13).

As a result of the determination in step S13, if the status of the subsystem in which the subscriber is mounted is not normal, the ACC block transmits IPC data to the corresponding guide terminal side through the DSI block and the BRI hardware module to serve on the monitor screen provided in the guide terminal. After outputting a system status error message (S14), the process branches to step S1.

However, if it is determined in step S13 that the status of the subsystem in which the subscriber is mounted is normal, the ACC block searches for various information stored in the system and collects various information about the subscriber (S15), and the corresponding guide (representative guide). After the IPC communication with the other side, the information of the specific subscriber collected (subscription of various additional services) is displayed on the monitor screen provided in the information terminal (S16), and then branches to step S1.

After the above process, when the information on the subscribers belonging to the group or other group to which the representative guide belongs is displayed on the monitor screen of the representative guide desk of the super group, the guide checks the subscriber information. Super group, that is, multiple CENTREX groups can be managed smoothly.

As described above, the present invention outputs the information of subscribers respectively subscribed to different CENTREX groups according to the request of the receptionist as one guide, so that the receptionist joins the other group through the monitor screen provided in his guide terminal. It is possible to easily check the information of subscribers (subscription of various supplementary services, etc.), which makes it possible to manage a large number of CENTREX groups at low cost.
