Description

Method for V5.2 Interface Deactivation

The present invention relates to a V5.2 interface deactivation method, and more particularly, a V5.2 interface deactivation method which can improve system performance by performing a V5.2 interface deactivation procedure normally during setup or configuration change of the V5.2 interface. It is about.

In general, the V5.2 protocol recommended by the International Telecommunication Union-Telecommunication standardization section (ITU-T) and the European Telecommunications standardization (ETSI), which is a European telecommunications standardization organization, It is a protocol applied to connect the interface between the Exchange (LE) and the Access Network (AN). The V5.2 interface supports various types of subscribers such as analog telephone connection, ISDN connection, and leased line connection.

The V5.2 interface activation between the switching system (LE) and the access network (AN) is not activated simultaneously with the switching system (LE) and the access network (AN), and when the V5.2 interface activation request is received by the operator, the data link is activated. It will continue to check and report L1 (Layer 1) until it is activated. In addition, it is judged that the other system is in the normal activation process by recognizing that the data link is activated in each system.

On the other hand, if the data link failure between the switching system (LE) and the access network (AN) occurs or if the V5.2 interface deactivation procedure is performed to stop each system, one of the switching system (LE) and the access network (AN) is Because the system only disconnects the data link of its own system to deactivate the V5.2 interface and does not notify the other system, other systems recognize that the data link is lost and continue to request data link activation.

Thus, the other system that was requested to deactivate the V5.2 interface could not determine whether the release of the data link was caused by a failure or the V5.2 interface deactivation procedure was performed by the operator's request.

As described above, the conventional V5.2 interface deactivation method simply disconnects the data link of the own system. Therefore, according to the V5.2 interface deactivation procedure, the other network, the access network or the switching system, recognizes that the deactivation is not performed and only determines that the data link is broken, so that the V5. Requires two interface activation.

In other words, the deactivation procedure of the V5.2 interface currently configured between the conventional switching system and the access network is different from the V5.2 interface activation procedure, so that the protocol recognition procedure is not performed between the access network and the switching system. There is a problem that an unstable V5.2 service is provided due to a state transition.

The present invention has been made in view of the above-described problems. When the V5.2 interface deactivation is performed between the switching system and the access network, an abnormal state mismatch of the counterpart system is recognized by recognizing a mutual protocol according to the corresponding V5.2 interface deactivation procedure. It aims to make the V5.2 system management more stable by ultimately managing the interface state of each system to facilitate maintenance aspects or shape changes.

2 is a flow chart illustrating a V5.2 interface deactivation method according to an embodiment of the present invention.

In order to achieve the above object, the present invention provides a method for deactivating a V5.2 interface between an access network and a switching system, wherein the first partner transitions the state of the V5.2 interface to the deactivation standby state, and the second partner V5. .2 waiting for a response from the second partner after requesting interface deactivation; The second partner is requested to deactivate the V5.2 interface and transmits a response to the first partner, transitions the state of the V5.2 interface to the deactivation standby state, and then releases the data link from the first partner. Waiting for notification; When the first partner receives a response to the V5.2 interface deactivation request from the second partner, it blocks each port and releases the data link of the corresponding V5.2 interface. Notifying release of data link of the two interfaces; Performing a V5.2 interface deactivation procedure by being informed of the data link release of the V5.2 interface by the second partner; If the first partner does not receive a response or an event for the V5.2 interface deactivation request from the second partner, both the first partner requesting the V5.2 interface deactivation or the second partner requesting the V5.2 interface deactivation. Self-deactivating the V5.2 interface.

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

The diagram for explaining a V5.2 interface deactivation method according to an embodiment of the present invention is the same as the V5.2 interface connection state between the general switching system and the access network shown in FIG.

In the present invention, when the data link between the switching system (LE) and the access network (AN) configured as described above fails or each system is to be stopped, the V5.2 interface deactivation protocol according to the operator's request is applied to the switching system (LE) or access. The network (AN) is notified to perform the corresponding V5.2 interface deactivation procedure. For example, the operation of deactivating by notifying the V5.2 interface deactivation protocol or method from the switching system (LE) to the access network (AN) is attached. 2 will be described with reference to FIG. 2.

First, the switching system LE transitions the state of the V5.2 interface to the inactive standby state, requests the deactivation of the V5.2 interface to the access network AN, which is the counterpart system (step S1), and then accesses the corresponding access network (AN). Wait for a reply from the server.

At this time, the access network AN transmits a response to the V5.2 interface when it is requested to deactivate the V5.2 interface, transitions the state of the V5.2 interface to the deactivation standby state (step S2). Wait until the data link release is notified from the switching system (LE).

When the switching system LE receives a response to the V5.2 interface deactivation request from the access network AN (step S3), the switching system LE blocks each port of its own system to disconnect the data link of the corresponding V5.2 interface. At the same time as the release, the access network (AN) side of the counterpart system is notified of the release of the data link of the corresponding V5.2 interface (steps S4 and S5). At this time, the state of the V5.2 interface of the corresponding switching system (LE) is changed to the system inactive state at system restart to be inactivated.

At this time, the access network (AN) is deactivated by the deactivation routine of the switching system (LE) until the data link release of the V5.2 interface is notified and the V5.2 interface immediately after the notification of the release of the data link. Deactivation procedure will be performed.

Meanwhile, in step S3, the corresponding switching system LE is in a waiting state for deactivating the V5.2 interface, and a normal response or event is not generated within a predetermined time period from the access network AN, which is the counterpart system, in response to the V5.2 interface deactivation request. Otherwise, after a predetermined time elapses, both the switching system LE requesting the V5.2 interface deactivation or the access network AN requesting the V5.2 interface deactivation deactivates the V5.2 interface itself. Step S6).

In performing the V5.2 interface deactivation as described above, the deactivation operation by notifying the V5.2 interface deactivation protocol or method from the access network (AN) to the switching system (LE) uses the same method as described above. Will be omitted.

Accordingly, the V5.2 interface deactivation procedure between the switching system and the access network according to the present invention allows recognition of the V5.2 interface protocol to prevent mutual transition of an abnormal system, and during setup of the V5.2 interface. By performing the deactivation procedure of the V5.2 interface according to the shape change, the performance of the V5.2 system can be improved.

As described above, when the V5.2 interface deactivation procedure is performed between the switching system and the access network, the present invention can recognize the mutual protocol according to the V5.2 interface deactivation procedure to compensate for an abnormal state mismatch of the counterpart system. Normal management of the V5.2 interface status of the system facilitates maintenance and shape changes, and ultimately more stable V5.2 system management.
