Description

Method of outputting call pick-up 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 switchgear, and in particular, through a specific guide, not only specific call tearing group information of a small group to which the guide belongs, but also information of a specific call cutting group registered to another small group. The present invention relates to a method of outputting call tearing group information through a guide of an 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 the guide where he or she works so as to subscribe to call cutting group information registered in the CENTREX group to which he belongs, that is, a subscriber who is subscribed to a call cutting group. The CENTREX group to which they belonged was managed by confirming their phone number and the required call cutting group number through the monitor screen provided on the information terminal. Here, a plurality of subscribers subscribed to the call truncation group may make a phone call with the calling party by cutting their own call to any subscriber belonging to the call truncation group.

However, in the related art, only the call truncation group information registered in the CENTREX group to which the guide belongs to can be checked through each guide arranged in some CENTREX groups, but the call truncation group information registered in the other CENTREX group is not known at all. The CENTREX Group, which did not have a guide, was not able to verify the information of call cutting groups registered in the group, and thus it was impossible to integrate and manage multiple CENTREX Groups.

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 call cutting groups registered in each CENTREX group belonging to the super group is output to the terminal of the representative reception desk, so that a plurality of groups can be saved at a low cost (reduction of the employment cost of the receptionist and the installation of the guide) The purpose of the present invention is to provide a method of outputting call tearing group information through a guide of an electronic switchboard, which can be efficiently managed.

In order to achieve the above object, the method for outputting call truncation group information through the guide of the electronic switchboard according to the present invention includes the call truncation through the guide of the electronic switchboard in which part or all of the subscribers are divided into several small groups. A call pick-up group information output method 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 judging whether the selected small group belongs to the corresponding super group when the information on the call cutting group registered in the other small group is requested from the representative guide; A third step of determining whether the selected call cutting group number is the number of the call cutting 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 call truncation group registered in the selected small group is provided, a fourth step of collecting information of each subscriber subscribed to the corresponding call truncation group and informing the corresponding guide is provided.

In addition, the present invention provides a step of notifying the small group number setting error message according to the guidance if the result of the determination in the second step does not belong to the corresponding supergroup, and the number of the call cutting group registered in the selected small group as a result of the determination in the third step is Otherwise, the step of notifying the call cutting group number setting error message may be 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.

5A and 5B, a process of outputting call truncation group information registered in each CENTREX group belonging to a super group through the representative guide of the super group, according to an embodiment of the present invention, is illustrated in FIGS. The description is as follows.

First, when a receptionist working at a representative information desk of a super group operates a key panel provided in the corresponding terminal and inputs a call cutting group information output command, the call cutting group information in which the information is input from the information terminal to the electronic switchboard. An output request message is sent. At this time, the attendant can enter the specific CENTREX group number and call cutting group number that you want to check with the command.

More specifically, the call truncation 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. The call truncation group information output request message is determined (S2).

As a result of the determination in step S2, if the control message is not the call truncation group 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 guide, it is determined whether or not there is a CENTREX group number in the call truncation 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, after step S9, the ACC block determines whether or not the requested call truncation group number in the call truncation group information output request message is a group number registered in the corresponding CENTREX group. If it is not determined (S10), if it is not valid, IPC data is transmitted to the guide terminal through the DSI block and the BRI hardware module so that a call tearing group number setting error message is displayed on the monitor screen provided in the guide terminal (S11). The process then branches to step S1.

However, if the requested call truncation group number is valid as a result of the determination in step S10, the ACC block searches various information stored in the system to determine whether there is a subscriber registered in the corresponding call truncation 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 guide terminal side so that a message indicating that there are no subscribers registered in the call cutting group is displayed on the monitor screen provided in the guide terminal. After step S13, the process branches to step S1, and if there are registered subscribers, the various number of information stored in the system is searched to obtain the total number of subscribers registered in the corresponding call cutting group (S14).

After step S14, the ACC block collects and stores the information of each subscriber subscribed to the corresponding call cutting group in order in the system (S15, S16, S17, and S18).

Thereafter, the ACC block displays the subscriber's telephone number and the call cutting group number in the specific call cutting group stored in IPC communication with the information desk (representative information desk) on the monitor screen provided in the information terminal. After step S19, the process branches to step S1.

When the information of the call cutting group registered in the small group belonging to the representative guide or another 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. Therefore, super group, that is, multiple CENTREX groups can be managed smoothly.

As described above, the present invention outputs the information of the call cutting group registered in the different CENTREX groups according to the request of the guide as one guide, so that the guide is another small group through the monitor screen provided in his guide terminal. It is easy to check the subscriber's phone number in the call dropping group registered at, which makes it possible to manage a large number of CENTREX groups at low cost.
