Description

Method of outputting hunting group'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 switchboard, and in particular, through a specific guide, so that not only the specific hunting group information of a small group to which the guide belongs, as well as the information of a specific hunting group registered in another small group. The present invention relates to a method of outputting hunting group information through a guide of an electronic exchange.

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 prior art, the receptionist communicates with the electronic switchboard through the guide terminal of the information desk where he or she works, and the hunting group information registered in the CENTREX group to which he belongs, that is, the telephones of the subscribers joined to the hunting group. The number and required hunting group number were checked through the monitor screen provided in the guide terminal to manage the CENTREX group to which they belong. Here, when another call is received while a subscriber joined the hunting group is busy, the call is received by another subscriber (preset) belonging to the hunting group so that the other subscriber can make a phone call with the calling party.

However, in the related art, only the hunting group information registered in the CENTREX group to which the guide belongs, was not able to know the hunting group information registered in the other CENTREX group at all through the guides arranged in some CENTREX groups. The CENTREX Group, where no guides were registered, also could not check the Hunting Group information registered 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 information of all the hunting groups registered in each CENTREX group belonging to the super group can be output to the terminal of the representative reception desk to efficiently manage multiple groups at a low cost (reduction of the cost of hiring a receptionist and reducing the installation cost of the guide). The purpose of the present invention is to provide a hunting group information output method through the guide of the electronic switchgear to be managed by.

Hunting group information output method through the guide of the electronic switchboard according to the present invention in order to achieve the above object is a hunting (hunting) through the guide of the electronic switchboard is divided into several small groups of some or all of the subscriber (hunting) A method for outputting group information, comprising: a first step of integrating a plurality of small groups into one super group and registering a representative guide in one of the small groups belonging to the super group; A second step of determining whether the selected small group belongs to the corresponding super group when the information of the hunting group registered in the other small group is requested from the representative guide; A third step of determining whether the selected hunting group number is the number of the hunting group registered in the selected small 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, if the number of the hunting group registered in the selected small group is characterized in that the fourth step of collecting the information of each subscriber subscribed to the corresponding hunting group and notifying according to the corresponding guide is provided.

In addition, the present invention, if the result of the determination of the second step does not belong to the corresponding super group, the step of notifying the small group number setting error message according to the guide, and as a result of the determination of the third step if the number of the hunting group registered in the selected small group The step of notifying the hunting group 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, the electronic exchange switch outputs hunting group information registered to each CENTREX group belonging to the super group through the representative guide of the super group, with reference to the flowcharts shown in FIGS. 5A and 5B. The explanation is as follows.

First, when a guide who works at the representative information desk of the super group operates a key panel provided in the corresponding terminal and inputs a hunting group information output command, the hunting terminal information output request is input from the information terminal to the electronic exchange. The message is sent. At this time, the guide may enter the specific CENTREX group number and hunting group number that you want to check with the command.

More specifically, the hunting group information output request message is transmitted to the ACC block of the ASP via the BRI hardware module of the electronic switchboard 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 hunting group information output request message (S2).

As a result of the determination in step S2, if the control message is not the hunting group information output request message, the ACC block branches to step S1 after processing the service corresponding to the message (S3), and if the hunting group information output request message is stored in the system, The information is searched 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 guide, it is determined whether a CENTREX group number exists in the hunting group 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).

As a result of the determination in step S7, the CENTREX group number in the super group or the ACC block after step S9 determines whether the required hunting group number in the hunting group information output request message is a group number registered in the corresponding CENTREX group, that is, it is determined to be valid. (S10) If it is not valid, the IPC data is transmitted to the guide terminal through the DSI block and the BRI hardware module so that a hunting group number setting error message is displayed on the monitor screen provided in the guide terminal (S11) and then step S1. Branch to

However, if the requested hunting group number is valid as a result of step S10, the ACC block searches for various information stored in the system and determines whether there is a subscriber registered in the corresponding hunting group (S12).

As a result of the determination in step S12, if there is no registered subscriber, the ACC block transmits IPC data to the information desk terminal so that a message indicating that no subscribers are registered in the corresponding hunting group is displayed on the monitor screen provided in the information desk terminal ( S13) and branches to step S1, and if there is a registered subscriber, retrieves various information stored in the system and acquires the total number of subscribers registered in the corresponding hunting group (S14).

After the step S14, the ACC block collects the information of each subscriber in the corresponding hunting group in turn in the system, and then performs the IPC communication with the information desk (representative information desk) to save each subscriber's phone number in the specific hunting group. And the hunting group number, etc. are displayed on the monitor screen provided in the guide terminal (S15, S16, S17, S18) and branches to step S1.

When the information of the hunting group registered in the small group belonging to the representative guide or other small group is displayed on the monitor screen of the representative guide desk terminal of the super group through the above process, the guide checks the information. Super group, that is, multiple CENTREX groups can be managed smoothly.

As described above, the present invention outputs the information of the hunting group registered in each of several different CENTREX groups as one guide according to the request of the guide. It is easy to check the subscriber's phone number in the registered hunting group, so that it is possible to manage a large number of CENTREX groups at low cost.
