Description

Method of changing status of the other information desks belong to the same group to one information desk in the digital switching system

The present invention relates to a method of changing the state of guides of an electronic switchgear, and in particular, one of a plurality of guides belonging to the same group can change the state of the other guides of the electronic switchboard. It is about.

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 Introduced the CENTRALized EXchange (CENTREX) feature, which allows users to call other subscribers in the same group using only the extension dial.

FIG. 2 is a diagram illustrating a connection state between a conventional electronic switch, a reception desk, and a subscriber in which a CENTREX function is introduced. A part or all of the subscribers connected to the same electronic switch are integrated into a plurality of CENTREX groups, and a maximum of one CENTREX group is included. Up to 10 guides are registered to perform the guide function for the group. More specifically, up to 1000 CENTREX groups may be accommodated in one electronic exchanger, and only one CENTREX group is shown in FIG. 2.

The subscribers registered in the CENTREX group are divided into several levels, so that some subscribers are restricted from calling outside the CENTREX group, and some subscribers can 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 of which outbound calls are limited.

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. The company provided various services and managed the CENTREX group.

On the other hand, in the case of the CENTREX group, calls from the outside are unconditionally connected to the subscribers in the called group only through guides belonging to the CENTREX group. .

However, in the related art, when a guide who worked at any one of several guides belonging to the same CENTREX group is away for a long time and normal service is not performed on the guide, the guide no longer receives a call as his guide. In order to prevent the guide from changing the status of the guide, if the guide cannot change the status of the guide, the external call will continue to be called despite the fact that the guide cannot perform the service normally. As a result, there was a problem that smooth services are not provided to the CENTREX group subscribers.

Therefore, in the related art, when the above-mentioned case occurs, the guidemen working in other guides have to go directly to the guides where the service is not normally performed and change the state of the guides.

The present invention has been made to solve the above problems, it is possible to change the state of a particular guide through the other guides belonging to the same CENTREX group as the guide can enable the provision of smooth guide service, The purpose of the present invention is to provide a method of changing the state of other guides of an electronic changer that can facilitate the use of a guide.

In order to achieve the above object, the method of changing the state of other guides according to the present invention is divided into a plurality of groups, and at least one guide is registered in each group. A state changing method, comprising: a first determining whether the second guide is present in the same group as the first guide when a state change of the second guide is requested from a first guide registered in one of the plurality of groups; Steps; If the second guide is in the same group as the first guide as a result of the determination of the first step, the state information of the second guide that has been stored inside the system is changed from the first guide to the requested state information. A second step; And a third step of outputting a state change message according to the second guide after the second step, and outputting a message indicating that the state of the second guide is changed according to the first guide.

In addition, the present invention preferably further comprises the step of outputting the guide selection error message according to the first guide when the second guide is not present in the same group as the first guide as a result of the determination of the first step. .

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

FIG. 3 is a diagram illustrating a connection state between an electronic switch, an information desk, and a subscriber for implementing the present invention, in which part or all of the subscribers connected to the same electronic switch are integrated into a plurality of CENTREX groups, and one CENTREX group includes a maximum of 10. FIG. The guide is registered to perform the guide function of the group up to, and in the case of the CENTREX group shown in FIG.

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. Deliver the necessary data (voice, digital data, etc.)

In addition, the guide is provided with a terminal provided with a key panel, a monitor screen, etc. The 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.

Referring to the flow chart shown in Figure 5 the process of changing the state of the other guide is required from the specific guide in accordance with an embodiment of the present invention configured as described above in detail as follows.

First, guides working on guide A (one of the guides capable of performing normal service) belonging to the same CENTREX group as guide B, who are unable to service properly, should The key panel provided in the guide terminal of the user is operated to input the state change command of the guide B. At this time, the guide enters the telephone number of guide B.

When the input of the state change command of the guide B is completed, the other guide stand state change request message including the input information is transmitted from the terminal of the guide A to the electronic switchboard. More specifically, another guide state change 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 information about each CENTREX group, information desk, subscriber, etc. is stored in the system of the electronic switchboard.

The ACC block determines whether a control message is received from a specific guide, as shown in FIG. 5 (S1). If an arbitrary control message is received, the ACC block determines whether the control message is another guide state change request message. (S2).

As a result of the determination of step S2, if the received control message is not the other guide state change request message, the ACC block branches to step S1 after processing the service corresponding to the message (S3), and if it is another guide station state change request message, the system It is determined whether the guide is a guide registered in any CENTREX group by searching various types of information stored therein (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 terminal of the representative guide through the DSI block and the BRI hardware module to display the guide without registration message on the monitor screen provided in the terminal. After step S5, the process branches to step S1, and if it is a registered guide, it is determined whether the guide required for the state change (selected by the guide) exists in the same CENTREX group as the guide that requested the state change (S6). .

If the selected guide is not present in the same CENTREX group as a result of step S6, the ACC block transmits IPC data to the terminal of the guide that has requested a state change through the DSI block and the BRI hardware module, and then displays the guide on the monitor screen provided in the terminal. After the selection error message is displayed (S7), the process branches to step S1.

However, if the selected guide is present in the same CENTREX group as a result of the determination of step S6, the ACC block changes the state information of the selected guide stored in the system to the requested state information (S8).

After the step S8, the ACC block transmits the IPC data to the terminal of the guide that requires a state change through the DSI block and the BRI hardware module so that a state change message is displayed on the monitor screen provided in the terminal (S9). IPC data is also transmitted to the terminal of the guide that has requested to display a message indicating that the state of the selected guide is changed on the monitor screen provided in the terminal (S10), and then branches to step S1.

For example, in the case of the CENTREX group shown in FIG. 3, a guide who works at the guide A that can perform the service normally cannot operate the key panel of the guide terminal to perform the service to the electronic switchboard side normally. When requesting a change of the status of guide B (Normal call no longer needs to be changed from normal mode to night service mode or position busy mode), the electronic switch is stored inside the system through the procedure described above. Change the status information of the guide B that was already in use so that the call is no longer called.

As such, the present invention facilitates the convenience of guides because the guides working on any guide can easily change the status of other guides registered in their group using their guide terminals. It is possible to provide a smooth service to the subscribers of the group at all times, and there is an effect of diversifying the information related to the guide.
