Abstract

PURPOSE: A method for changing abbreviated dial information through an operator system of a full electronic exchange is provided to integrate CENTREX(Centralized Exchange) groups into one super group in order to share abbreviated dial information of every CENTREX group included in the super group, and to register a representative operator system in a specific CENTREX group included in the super group in order to change abbreviated dial information registered in a desired group included in an identical super group through one operator system. CONSTITUTION: Many groups are integrated into one super group, and a representative operator system is registered in one of the groups included in the super group. If change of abbreviated dial information registered in another group is requested from the representative operator system, whether the selected group is included in an identical super group with the corresponding representative operator system is decided. If included, whether a change-requested abbreviated dial code is registered in the selected group is decided. If registered, errors of a telephone number to be changed are checked. If errors do not exist in the telephone number to be changed, a telephone number pre-allocated to the change-requested abbreviated dial code is changed to a new telephone number, and a change result is reported to the corresponding representative operator system.

Description

Method of changing abbreviated dial information to the information desk in the digital switching system

The present invention relates to a method of changing information through a guide of the electronic switchboard, and in particular, a guide of the electronic switchboard, which allows not only the group to which the guide belongs, but also the speed dial information registered in another group through a specific guide. The present invention relates to a method of changing speed dial information through a stand.

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 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.

On the other hand, in the past, the receptionist changes the speed dial information (telephone number assigned to the speed dial code) registered in the CENTREX group to which the attendant communicates with the electronic switchboard through the terminal of the information desk where he works. The result could be confirmed through the monitor screen provided in the terminal.

In general, abbreviated dialing refers to a service that allows a specific communication party to be called by a short-digit dial operation, and part of the other party's telephone number may be registered as a speed dial code.

Therefore, any attendant can change the phone number assigned to the speed dial code of the CENTREX group to which the CENTREX group belongs to the new phone number whenever necessary and the subscribers of the CENTREX group want to use the speed dial function. It can be used as it is.

However, in the related art, only the speed dial information registered in the CENTREX group to which the guide belongs to can be changed through a specific guide, but the speed dial information registered in the other CENTREX group cannot be changed. In order to make the change, at least one guide should be registered for each CENTREX group, so there was a problem in that it was expensive to install guides and hire guides.

The present invention has been made to solve the above problems, by combining a plurality of CENTREX groups into one super group so that the speed dial information of all the CENTREX group belonging to the super group is shared, the specific CENTREX group belonging to the super group How to change the speed dial information through the information desk of the electronic switchgear, which registers the representative information desk only, so that the speed dial information registered in the desired group among the multiple CENTREX groups belonging to the same super group can be changed through one guide. The purpose is to provide.

In order to achieve the above object, a method of changing speed dial information through a guide of an electronic switch in accordance with the present invention is a speed dial information through a guide of an electronic switch in which part or all of the subscribers are divided into several groups. A modification method comprising: 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 same super group as the representative guide when a change of speed dial information of another group is requested from the representative guide; A third step of judging whether the speed dial code requested for change is registered in the selected group if the selected group belongs to the same super group as the representative guide as a result of the determination in the second step; A fourth step of checking whether there is an error of the telephone number to be changed if the speed dial code requested to be changed is registered in the selected group as a result of the determination of the third step; If there is no error in the telephone number to be changed as a result of the inspection of the fourth stage, a fifth stage is provided in which the telephone number assigned to the requested speed dial code is changed to a new telephone number and the result is reported according to the representative guide. It is characterized by.

According to the present invention, if the selected group does not belong to the same super group as the representative guide, outputting the group number selection error message according to the representative guide, and shortening required to change the determination result of the third step. If the dial code is not registered in the selected group, the method may further include outputting a speed dial code selection error message according to the representative guide.

In addition, the fourth step of the present invention includes the first step of determining whether the telephone number to be changed is selected in the corresponding group; If the telephone number to be changed is selected inside the group as a result of the determination of the first step, the number of digits of the telephone number is the same as the extension number of the group, and the first digit does not start with 0, 1, 8 or 9; A second process of determining whether the number is a member of the corresponding group; A third step of determining whether the phone number is a number subscribed to another group or another electronic switch when the telephone number to be changed is selected outside the corresponding group as a result of the determination of the first step; As a result of the determination of the second and third processes, if all conditions are satisfied, it is preferable that a fourth process of recognizing that there is no error in the telephone number to be changed is provided.

In the fourth step, if any one condition is not satisfied as a result of the determination of the second process, the method may include outputting a phone number selection error message according to the representative guide; If the number is not subscribed to another electronic switch, it is preferable to further include a step of outputting a telephone number selection error message according to the representative guide.

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

3 is a diagram illustrating a state of connection between an electronic switch, a reception desk, and a subscriber for implementing the present invention, in which some or all of the subscribers connected to the same electronic switch are bundled into a plurality of CENTREX groups (A, B). 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 to the representative guide.

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

The representative guide is connected to the electronic switching system using BRI, an ISDN interface, and the 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 representative 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 flowcharts shown in FIGS. 5A to 5C, the process of changing the speed dial information requested from the representative guide according to an embodiment of the present invention will be described below.

First, when a guide attending a representative of the super group operates a key panel provided in the terminal and inputs a command to change speed dial information, the guide terminal requests to change the speed dial information including the input information from the terminal to the electronic exchange. The message is sent. At this time, the attendant can insert the desired CENTREX group number in the speed dial information change command, and the speed dial code and the telephone number to be newly assigned to the code must be inserted.

The speed dial information change request message is more specifically transmitted to the ACC block of the ASP via the BRI hardware module of the electronic switch 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 to 5C, the ACC block determines whether to transmit a control message from a specific representative guide (S1). If an arbitrary control message is received, whether the control message is a speed dial information change request message. Determine (S2).

If the received control message is not a speed dial information change request message, the ACC block branches to step S1 after processing the service corresponding to the message (S3). The stored information is searched to determine whether the representative guide is a registered guide (S4).

As a result of the determination in step S4, if the representative 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 so that the guide unregistered message is displayed 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 a CENTREX group number exists in the speed dial information change request message (S6).

If the CENTREX group number is found in the message at step S6, that is, if the guide selects a specific CENTREX group number, the ACC block searches for various information stored in the system and the CENTREX group number is in the same super group as the representative guide. It is determined whether the group number belongs (S7).

As a result of the determination in step S7, if the CENTREX group number is not a group number belonging to the same super group as the representative guide, the ACC block transmits IPC data to the terminal of the corresponding guide through the DSI block and the BRI hardware module. After the CENTREX group number selection error message is displayed on the monitor screen (S8), the process branches to step S1.

On the other hand, if there is no CENTREX group number in the message as a result of the determination in step S6, that is, if the guide did not select a specific CENTREX group number, the ACC block obtains the CENTREX group number to which the corresponding representative guide belongs (S9).

As a result of judgment in step S7, the corresponding CENTREX group number is a group number belonging to the same super group as the representative guide, or after step S9, the ACC block searches for various information stored in the system and the speed dial code requested to be changed is assigned to the corresponding CENTREX group. It is determined whether it is registered (S10).

As a result of the determination in step S10, if the requested speed dial code is not registered in the corresponding CENTREX group, the ACC block transmits IPC data to the terminal side of the representative guide through the DSI block and the BRI hardware module, and then displays it on the monitor screen provided in the terminal. After the speed dial code selection error message is displayed (S11), the process branches to step S1.

However, if the speed dial code requested to be changed is registered in the corresponding CENTREX group, the ACC block checks the speed dial information change request message and the attendant selects between the GI (Group In) type and the GO (Group Out) type. It is determined what type is selected (S12).

In the above, the selection of the GI type means that the telephone number to be changed is selected from the internal telephone numbers (extension numbers) of the CENTREX group, and the selection of the GO type joins the external telephone number of the corresponding CENTREX group, that is, the same telephone exchange. Selected telephone numbers from other CENTREX groups or telephone numbers subscribed to other electronic switching centers.

As a result of the determination in step S12, when the guide selects the GI type, the ACC block determines whether the number of the telephone number to be newly allocated to the requested speed dial code is the same as the extension number of the corresponding CENTREX group (S13). It is determined whether the first number of starts with 0, 1, 8 or 9 (S14), and it is determined whether the telephone number is a number subscribed to the CENTREX group (S15).

As a result of the judgment in the steps S13, S14, and S15, the number of the telephone number to be changed is different from the extension number of the corresponding CENTREX group, or the first number of the telephone number starts with 0, 1, 8 or 9, or the telephone number is If the number is not subscribed to the CENTREX group, the ACC block transmits IPC data to the terminal of the representative guide through the DSI block and the BRI hardware module so that a telephone number selection error message is displayed on the monitor screen provided in the terminal (S16). Branch to step S1).

However, as a result of judging in steps S13, S14, and S15, the number of digits to be changed is the same as the extension number of the corresponding CENTREX group, and the first digit of the telephone number does not start with 0, 1, 8 or 9, and the call If the number is a member of the CENTREX group, the ACC block changes the phone number assigned to the requested speed dial code of the CENTREX group to a new phone number (S17), and then the representative through the DSI block and the BRI hardware module. The IPC data is transmitted to the terminal of the information desk so that a message indicating that the requested speed dial information has been changed is displayed on the monitor screen provided in the terminal (S18).

Usually in the CENTREX group, the number 0 is used to call the information desk, the number 1 for numbers 114 and 119, the number 8 for the 800 service, and the number 9 for capturing the outside number. Since each telephone number that is started is not used as an extension number, if the first digit of the telephone number to be changed starts with 0, 1, 8 or 9, it is determined as a selection error of the telephone number.

On the other hand, if the guide selects the GO type as a result of the determination in step S12 ACC block determines whether the telephone number to be changed is a number subscribed to another CENTREX group or another electronic switch (S19).

As a result of the determination in step S19, if the telephone number to be changed is not a number subscribed to another CENTREX group or another electronic switch, the ACC block transmits IPC data to the terminal side of the corresponding representative guide through the DSI block and the BRI hardware module. After the phone number selection error message is displayed on the monitor screen (S20), the process branches to step S1.

However, if it is determined in step S19 that the telephone number to be changed is a number subscribed to another CENTREX group or another electronic exchange, the ACC block changes the telephone number assigned to the requested speed-dial code of the CENTREX group to the new telephone number. After sending the IPC data to the terminal of the representative guide through the DSI block and the BRI hardware module, a message indicating that the requested speed dial information has been changed is displayed on the monitor screen provided in the terminal (S18). Branch to the step.

Therefore, the attendant working at the representative information desk changes the speed dial information registered in the desired CENTREX group among the plurality of CENTREX groups belonging to the corresponding super group at any time through his information desk terminal, and sends the processing result to the corresponding terminal. It could be confirmed through the monitor screen provided.

As described above, the present invention allows the speed dial information of a plurality of groups to be shared so that a specific guide person can easily change the speed dial information registered in the other group as well as the group to which the specific guide is provided. This enables the integrated management of speed dial information of multiple CENTREX groups and the reduction of administrative costs (reduced cost of guides and hire of guides).
