Abstract

In the present invention, when a subscriber is created or deleted on the LE side, both the AN and the LE side maintain the same state of the created or deleted subscriber in the same state, thereby providing a communication service for the subscriber. The present invention relates to a method of creating / deleting subscribers in the V5.2 protocol to allow normal processing.

In the present invention, when the LE side creates or deletes a subscriber, the LE side sends a port control message requesting the AN side to block or unblock the generated or deleted subscriber. Since the state of the deleted subscriber is maintained to be the same, if the subscriber is created on the LE side while the state of the subscriber is blocked on the AN side, the state of the subscriber becomes identical between the LE and AN. Incoming / outgoing call processing can be established correctly, and if the LE is deleted by the LE for a normal subscriber whose state is the same between LE and AN, the state of the subscriber becomes identical between LE and AN. There is no unreasonable situation where a call setup request message from an AN is unnecessarily passed from AN to LE. Neunda.

Description

Method for Processing Subscriber Creation and Deletion in V5.2 protocol

The present invention relates to a V5.2 protocol for matching and communicating between an access network (AN) and a local exchange (LE). Particularly, when an subscriber is created or deleted on the LE side, both the AN side and the LE side are generated or The present invention relates to a method of creating / deleting a subscriber in the V5.2 protocol for allowing a communication service for a corresponding subscriber to be normally processed by maintaining a state of a deleted subscriber.

In general, the V5.2 protocol is used when the AN and the LE communicate with each other in the communication system. When the subscriber creates or deletes a subscriber on the LE side, the AN side and the LE in order to normally perform communication services for the corresponding subscriber are used. Both sides need to keep the state of the subscriber in the same state.

However, existing recommendations related to the V5.2 protocol (ETS 300 324-1, ETS 300 347-1) do not recommend a scheme for matching the corresponding subscriber state between AN and LE when creating / deleting subscribers on the LE side. .

Accordingly, in the conventional communication system using the V5.2 protocol, when the subscriber is created on the LE side while the state of the subscriber is blocked on the AN side, the state of the subscriber becomes different between the LE and the AN. There is a problem that the incoming / outgoing call processing to the subscriber is not established.

In addition, in a conventional communication system using the V5.2 protocol, when a subscriber is deleted on the LE side for a normal subscriber whose state is identical to LE and AN, the state of the subscriber becomes different between LE and AN. There is a problem in that a call setup request message from N is unnecessarily transmitted from AN to LE.

The present invention has been made to solve the problems described above, the object of which is that when the subscriber is created or deleted on the LE side, both the AN and LE side keeps the state of the subscriber is created or deleted in the same state By providing a method for creating / deleting a subscriber in the V5.2 protocol to allow a communication service to a corresponding subscriber to be normally processed.

In order to achieve the above object, a feature of the present invention is to send a port control message requesting to block the generated subscriber when the subscriber is created on the LE side to the AN side of the generated subscriber. Creating a subscriber to switch the port to an unblocking state; And a subscriber deletion process of switching a port of the deleted subscriber to a blocking state by transmitting a port control message requesting blocking the deleted subscriber to the AN when the subscriber is deleted on the LE side. have.

On the other hand, in the subscriber generation process, the data handler receives a control command requesting the creation of a subscriber from the MMI, adds the requested subscriber to the subscriber database, updates and records the subscriber, and sends the V5.2 system manager to the V5.2 system manager. Notifying the creation; The V5.2 system manager being notified of the creation of the V5.2 subscriber, searching for the V5.2 interface and the port, and sending an available message primitive for the creating subscriber to the control protocol entity of the corresponding V5.2 interface; Sending a port control message to the AN side requesting that the control protocol entity receive the available message primitive to unblock a generating subscriber; Receiving, by the AN, the port control message, transmitting a port control response message to the LE, and translating the corresponding subscriber port accommodated therein to the unblocking state.

In addition, the subscriber deletion process, the data handler receives a control command requesting the deletion of the subscriber from the MMI, and deletes the requested subscriber from the subscriber database to update and record the subscriber to the V5.2 system manager. Notifying the deletion; The V5.2 system manager being notified of the deletion of the V5.2 subscriber, searching for the V5.2 interface and the port, and sending an unusable message primitive for the created subscriber to the control protocol entity of the corresponding V5.2 interface; Sending, by the control protocol entity, a port control message to the AN side requesting to block the deleting subscriber by receiving the unusable message primitive; Receiving, by the AN, the port control message, transmitting a port control response message to the LE, and translating the corresponding subscriber port accommodated therein to the blocking state.

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

The subscriber generation / deletion processing apparatus in the V5.2 protocol according to the present invention is made as shown in FIG. That is, the AN 10 and the LE 20 are connected via a communication line, and the LE 20 is connected to the MMI (Man Machine Interface), the data handler 22, the subscriber database 23, and the V5.2 system manager. 24 and a Control Protocol Entity 25. The MMI 21 inputs a control command to the data handler 22 in which the system operator requests creation and deletion of a subscriber. The data handler 22 adds or deletes the information of each subscriber to the subscriber database 23 by adding or deleting information on the subscriber who has been requested to be created or deleted according to the subscriber creation / deletion request control command authorized through the MMI 21. It updates and manages and notifies the V5.2 system manager 24 of the fact that the V5.2 subscriber is created / deleted. The V5.2 system manager 24 discovers the creation / deletion of the V5.2 subscriber from the data handler 22, searches for the V5.2 interface and port, and creates the generated control protocol entity 25 of the corresponding V5.2 interface. Send an unusable message primitive to a subscriber or an unusable message primitive to a deleted subscriber. In addition, the control protocol entity 25 receives the port control message (FE201 / 202) from the V5.2 system manager 24 and requests the unblocking of the generating subscriber upon receiving an available message primitive. On receipt of the unusable message primitive from the V5.2 system manager 24, it sends a port control message (FE203 / 204) to the AN 10 requesting to block the deleting subscriber. In addition, when the AN 10 receives the port control message FE201 / 202 from the control protocol entity 25, the AN 10 transmits a port control response message to the control protocol entity 25 of the LE 20, and receives the corresponding port received from the control protocol entity 25. Transitioning the subscriber port to an unblocking state makes the generated V5.2 subscriber available, and receiving a port control message (FE203 / 204) from the control protocol entity 25 controls the control protocol entity of the LE 20 ( In addition to sending a port control response message to the 25) side, the corresponding subscriber port accepted by the user is transferred to the blocking state, thereby making the deleted V5.2 subscriber unavailable.

The subscriber generation process in the subscriber generation / deletion processing apparatus in the V5.2 protocol according to the present invention configured as described above is performed in the order shown in FIG.

First, when the MMI 21 requests a subscriber to generate a control command requesting the generation of a subscriber authorized by the system operator (step S21), the data handler 22 sends the MMI 21 to it. The subscriber generation request control command authorized through the program is received, and the corresponding subscriber is requested to be added to the subscriber database 23 and updated and recorded (step S22). When the subscriber addition process to the subscriber database 23 is normally performed in the data handler 22 as described above, the data handler 22 notifies the V5.2 system manager 24 that the V5.2 subscriber is created ( Step S23). At this time, the V5.2 system manager 24 is notified of the creation of the V5.2 subscriber from the data handler 22, and searches for the V5.2 interface and the port to generate to the control protocol entity 25 of the corresponding V5.2 interface. Send a free message primitive to the subscriber (step S24), and the control protocol entity 25 receives a free message primitive from the V5.2 system manager 24, requesting to unblock the producing subscriber. (FE201 / 202) is transmitted to the AN 10 side (step S25). Accordingly, when the AN 10 receives the port control message FE201 / 202 from the control protocol entity 25, it transmits the port control response message to the control protocol entity 25 side of the LE 20 (step S26). The corresponding subscriber port accommodated in the UE is shifted to an unblocking state, thereby making the generated V5.2 subscriber available (step S27).

Further, subscriber deletion processing in the subscriber generation / deletion processing apparatus in the V5.2 protocol according to the present invention is performed in the order shown in FIG.

First, when the MMI 21 requests a deletion of a subscriber by applying a control command to the data handler 22 requesting the deletion of an authorized subscriber from the system operator (step S31), the data handler 22 sends the MMI 21 to it. Upon receiving the subscriber deletion request control command authorized through this, the subscriber requested to be deleted is deleted from the subscriber database 23 to update the subscriber database 23 (step S32). When the subscriber deletion process on the subscriber database 23 is normally performed in the data handler 22 as described above, the data handler 22 notifies the V5.2 system manager 24 of the deletion of the V5.2 subscriber ( Step S33). At this time, the V5.2 system manager 24 is notified of the deletion of the V5.2 subscriber from the data handler 22, searches for the V5.2 interface and the port, and deletes it to the control protocol entity 25 of the corresponding V5.2 interface. Send an unusable message primitive for the subscriber (step S34), and the control protocol entity 25 receives a port control message (blocking the delete subscriber) upon receiving an unusable message primitive from the V5.2 system manager 24. The FE203 / 204 is transmitted to the AN 10 side (step S35). Accordingly, when the AN 10 receives the port control message FE203 / 204 from the control protocol entity 25, the control protocol entity of the LE 20 is transmitted. A port control response message is sent to the (25) side (step S36), and the corresponding subscriber port accommodated by the user is transferred to the blocking state, thereby making the deleted V5.2 subscriber unavailable (swap). S37).

That is, in the present invention, when the LE 20 creates or deletes a subscriber, the LE 20 sends a port control message requesting the AN 10 to block or unblock the created or deleted subscriber. By transmitting, the state of the subscriber created or deleted is maintained to be the same on both the LE 20 and the AN 10 side, so that the state of the subscriber on the AN 10 side is blocked while the LE 20 side is blocked. If the corresponding subscriber is created in the state of the subscriber between the LE (20) and the AN (10), the incoming / outgoing call processing for the newly created subscriber can be accurately established, LE (20) and AN (10) If the corresponding subscriber is deleted by the LE 20 for a normal subscriber whose status is identical, the call setup request message from the deleted subscriber becomes identical because the status of the corresponding subscriber is identical between the LE 20 and the AN 10. Unnecessarily to AN (10) This absurd situation that is passed to the emitter LE (20) does not occur.

As described above, when the subscriber is created or deleted on the LE side, both the AN side and the LE side maintain the same state of the created or deleted subscriber in the same state, so that the communication service for the subscriber is normally processed. do.
