Description

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

The present invention relates to a method for deleting information through a guide of an electronic switchboard, and more particularly, to a speed dial information of another group as well as speed dial information of a group to which the guide belongs, through a specific guide. The present invention relates to a method for deleting speed dial information through a guide.

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, conventionally, the receptionist deletes the speed dial information (telephone number assigned to the speed dial code) registered in the CENTREX group to which he belongs by communicating with the electronic switchboard through the terminal of the information desk where he works. It 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 guide person manages the speed dial information of the CENTREX group by deleting the desired speed dial information among the speed dials registered in the CENTREX group to which he / she belongs using the guide terminal whenever necessary.

However, in the past, only the speed dial information of the CENTREX group to which the guide belongs to can be deleted through a specific guide, but the speed dial information registered to another CENTREX group and the speed dial information of the CENTREX group to which the guide is not registered can be deleted. In order to manage speed dial information of a plurality of CENTREX groups, at least one guide must be registered for each CENTREX group. Therefore, it is expensive to install guides and hire guides.

In addition, conventionally, there is a problem that cannot collectively manage speed dial information of a plurality of CENTREX groups.

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 You can reduce the cost of installing guides and the cost of hiring guides by registering representative guides within the group so that speed dial information for multiple CENTREX groups belonging to the same super group can be deleted through the corresponding guides. It is an object of the present invention to provide a method of deleting speed dial information through a guide of an electronic switchgear that can integrate and manage speed dial information of a group.

In order to achieve the above object, the method for deleting speed dial information through the guide of the electronic switchboard according to the present invention includes the speed dial information through the guide of the electronic switchboard in which part or all of the subscribers are divided into several groups. An output 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 deletion of speed dial information registered in another group is requested from the representative guide; A third step of determining whether deletion of all speed dial information is required 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 deleting all speed-dial information registered in the selected group and reporting the result according to the corresponding guide when the deletion of all speed-dial information is requested as a result of the determination of the third step; When the deletion of the specific speed dial information is requested as a result of the determination of the third step, a fifth step of deleting the corresponding speed dial information registered in the selected group and reporting the result according to the representative guide is provided.

The present invention preferably further comprises the step of outputting a group number selection error message according to the representative guide if the selected group does not belong to the same super group as the representative guide as a result of the determination of the second step.

The fifth step of the present invention may include a first process of deleting selected speed dial information registered in a selected group, a second process of determining whether a speed dial registered in the selected group exists after the first process; A third step of outputting a message indicating that the requested speed dial information has been deleted according to the representative guide when there is a speed dial registered in the selected group as a result of the determination of the second step; If there is no speed dial, the fourth step of outputting a message indicating that there is no speed dial registered 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 flow chart shown in Figs. 5a and 5b the process of deleting the speed dial information requested from the representative guide in accordance with an embodiment of the present invention configured as described above.

First, if a receptionist working at a representative information desk of a super group operates a key panel provided in the terminal and inputs a command to delete speed dial information, the information terminal requests deletion of the speed dial information with the input information from the information terminal. The message is sent. At this time, the guide may insert the desired CENTREX group number and the speed dial code into the speed dial information deletion command.

The speed dial information deletion 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 and 5B, the ACC block determines whether to transmit a control message from a specific representative guide (S1). If an arbitrary control message is received, the ACC block determines whether the control message is a speed dial information deletion request message. Determine (S2).

If the received control message is not a speed dial information deletion 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 deletion 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 the determination 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 checks the speed dial information deletion request message to determine whether deletion of all speed dial information is required. (S10).

As a result of the determination in step S10, if the deletion of all the speed dial information is requested, the ACC block deletes all the speed dial information registered in the corresponding CENTREX group, that is, the telephone number assigned to each speed dial code in the system (S11). The speed dial mode of the CENTREX group is deleted (S12).

After the step S12, the ACC block transmits IPC data to the terminal side of the representative guide through the DSI block and the BRI hardware module so that a message indicating that there is no speed dial registered in the corresponding CENTREX group is displayed on the monitor screen provided in the terminal. (S13) It branches to the next step S1.

On the other hand, if the deletion of the specific speed dial information is requested as a result of step S10, the ACC block determines whether the requested speed dial code is registered in the corresponding CENTREX group (S14).

As a result of the determination in step S14, if the requested speed dial code is not registered in the corresponding CENTREX group, the ACC block transmits the 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. The speed dial code selection error message is displayed (S15), and the flow branches to step S1.

However, if it is determined in step S14 that the requested speed dial code is deleted in the corresponding CENTREX group, the ACC block deletes the required speed dial information of the CENTREX group, that is, the telephone number assigned to the selected speed dial code in the system. (S16).

After the step S16, the ACC block is registered in the corresponding CENTREX group, that is, acquires the number of remaining speed dials (S17) and determines whether there is a speed dial registered in the corresponding CENTREX group (S18).

As a result of the determination in step S18, if there is a speed dial registered in the corresponding CENTREX group, the ACC block sends IPC data to the terminal side of the corresponding guide through the DSI block and the BRI hardware module, and the speed dial requested to be deleted on the monitor screen provided in the terminal. A message indicating that the information has been deleted is displayed (S19), and then branches to step S1.

However, if it is determined in step S18 that there is no speed dial registered in the corresponding CENTREX group, the ACC block cancels the speed dial mode of the corresponding CENTREX group (S12) and then the IPC data to the terminal side of the representative guide through the DSI block and the BRI hardware module. In order to display a message indicating that there is no speed dial registered in the corresponding CENTREX group on the monitor screen provided in the terminal (S13), the process branches to step S1.

Therefore, the receptionist working at the representative information desk deletes the speed dial information of the plurality of CENTREX groups belonging to the corresponding super group at any time through their guide terminal, and confirms the result of the processing through the monitor screen provided in the terminal. Could.

As described above, the present invention allows a specific guide to easily delete speed dial information registered in another group through a terminal provided at the information desk where he or she works, and deletes the speed dial information through the monitor screen of the corresponding terminal. This allows the speed dial information of multiple CENTREX groups to be integrated and managed, while reducing administrative costs (reducing the cost of installing guides and hiring costs for guides).
