Description

V5.2 Status Information Management System using External Host in Electronic Switching System

The present invention relates to an electronic switch, in particular, having a separate host for managing the V5.2 subscriber status information and link status information outside the electronic switch that accommodates the V5.2 interface to manage independently The present invention relates to a V5.2 status information management device using an external host in an electronic switch that enables to increase the number.

Currently, electronic exchanges are used for local and local / tandom applications. Ultimately, electronic exchanges have been developed to develop into flexible exchanges in various networks such as integrated information and communication networks (ISDN) and intelligent networks. .

And, as is well known in the art, the V5.2 interface is the signaling protocol between the access network (AN) and the exchange recommended in European Telecommunication Standards (ETS) 300 and 347-1. . Here, the access network is a communication network capable of accepting analog and digital subscribers and communicating with an exchange for a V5.2 interface, and the exchange is an exchange capable of accepting subscribers by interfacing with an access network through a V5.2 interface.

On the other hand, the service of the public switched network (PSTN) or ISDN (Intergrated Service Digital Network) subscriber using the conventional electronic switchboard was only available to the subscribers who are directly connected by physical circuits to a predetermined subscriber interface device inside the switchboard.

In addition, in order to accommodate subscribers remote from the electronic switchgear, the call processing was performed by placing a sub-system equipped with both the existing electronic switchgear and software or hardware resources at a long distance. Accordingly, this sub-system has a disadvantage in that the price is high because it must have all the hardware or software resources of the existing electronic switchboard. In addition, this sub-system cannot handle processing of subscriber information, and is actually controlled by an electronic switch.

Therefore, recently, as mentioned above, it does not have the hardware or software resources of the electronic switchboard, and has an access network that transmits analog line status information to the electronic switchboard on the V5.2 interface without controlling direct call processing. This not only reduces system cost but also facilitates overall call control of all electronic switchboards.

However, the same link state management apparatus is used to manage the link state of the general public switched network subscriber directly connected to the electronic switchboard through the physical line and the E1 link state of the V5.2 subscriber, which enables the V5.2 interface. It is very inefficient to manage them or to install them in the electronic switchboard.

Accordingly, the present invention was created in view of the above circumstances, and is independently managed by having a separate host for managing V5.2 subscriber status information and link status information outside the electronic switchboard accommodating the V5.2 interface. The purpose of the present invention is to provide a V5.2 status information management device using an external host in an electronic switch that can increase management efficiency.

Control signal is transmitted to the V5.2 state management unit 16 or a predetermined signal input from the V5.2 state management unit 16 is transmitted to the call control unit 10 or the V5.2 interface control unit 13.

On the other hand, reference numeral 20 is a V5.2 interface unit of the remote subscriber unit for interfacing the V5.2 interface unit 12 and the V5.2 interface protocol, 21 is a public switched network or ISDN subscriber connected directly by a physical circuit As a remote subscriber matching unit for matching the data, the remote subscriber matching unit 21 receives a signal corresponding to a predetermined signal (for example, an off-hook signal) in response to a change in the subscriber state from the subscriber. The subscriber's state is adjusted based on a control message for the subscriber's state output to the interface unit 20 or input through the V5.2 interface unit 20. Here, the remote subscriber matching unit 21 may simultaneously control access to an analog subscriber, a basic rate interface (BRI), a primary rate interface (PRI), an analog relay line, a digital relay line, and a remote switching device.

Next, the operation of the device having the above configuration will be described in more detail. First, a management operation using an external host when generating new state data for a V5.2 interface link state and a subscriber state will be described with reference to the operation flowchart of FIG. 2.

In the normal state, the call control unit 10 transmits the subscriber state data from the call control message processing unit 11 to the external host connection unit 15, and the V5.2 interface control unit 13 transmits the V5.2 interface unit. When the link state data is received from 12, it is transmitted to the external host connection unit 15 (ST1, ST2 steps). Subsequently, the external host connection unit 15 outputs the input subscriber state data or link state data to the V5.2 state management unit 16 coupled through a predetermined physical line (step ST3).

The V5.2 state manager 14 determines whether the subscriber state data or the link state data input through the external host connection unit 15 is valid data (step ST4). Subsequently, if each state data is not valid data, the V5.2 state manager 14 outputs a predetermined error message to the external host connection unit 15 (step ST5). Then, the external host connection unit 15 outputs the input error message to the call control unit 10 or the V5.2 interface control unit 13.

On the other hand, the V5.2 state management unit 16 matches each other with the received state data and the link state data of the existing subscribers in the database when the received state data has a valid data format. The data is compared (step ST6, ST7). The V5.2 state management unit 14 outputs a predetermined result signal to the external host connection unit 15 when the respective state data compared with each other match, and the external host connection unit 15 outputs the result signal. Output to call control unit 10 and V5.2 interface control unit 13, respectively (ST8 step).

On the other hand, the V5.2 state management unit 16 updates and registers the subscriber state memory area and the link state memory area of the subscriber with the received state data, respectively, when two state data compared with each other do not match. ST9 step).

Next, a management operation using an external host when an inquiry or change request of a V5.2 interface link state and a subscriber state is requested from an external operator will be described with reference to the operation flowchart of FIG. 3.

When the system controller 14 receives an inquiry or change request signal for the V5.2 interface link state and subscriber state from the operator (step ST11), the system controller 14 receives the received V5.2 interface link state and subscriber. The inquiry or change request signal for the status is transmitted to the V5.2 interface controller 13 (step ST12).

Subsequently, the V5.2 interface control unit 13 transmits a corresponding inquiry or change request signal to the external host connection unit 15 according to the predetermined inquiry or change request signal received from the system controller 14 ( ST13 step). The external host connection unit 15 outputs the input inquiry or change request signal to the V5.2 state management unit 16 directly coupled through the physical line (step ST14).

V5.2 The state management unit 16 reads the corresponding link state information and subscriber state information stored in the database based on the inquiry or change request signal of the state data and compares them with the received link state information and subscriber state information, respectively. Then, it is determined whether or not the state data compared with each other match (step ST15).

After comparing each state data, the V5.2 state management unit 16 outputs a predetermined result signal to the external host connection unit 15 as to whether or not the state data to be compared is identical, and this external host connection unit 15 ) Outputs the input result signal to the V5.2 interface controller 13. Then, the V5.2 interface controller 13 outputs the resultant signal to the system controller 14 (step ST16).

On the other hand, the V5.2 state management unit 16 updates and registers the existing state data memory area with the received state data when the two state data do not match in the state data comparison step of step ST14 (step ST17).

Therefore, according to the above, it is possible to manage one or more V5.2 subscriber status information and link status information existing in one electronic switch using a separate external host very efficiently.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary.
