Abstract

PURPOSE: A method for managing a subscriber port state, is provided to prevent an unnecessary action of a system, caused by a subscriber who is not provisioned actually, and to prevent a mismatch on the subscriber port state between an AN system and a local exchange(LE) system. CONSTITUTION: A method for managing a subscriber port state, in a method of a full port unblock process of a startup flow between an AN system and a local exchange(LE) system according to an integrated digital loop carrier(IDLC) V5.2 protocol, comprises the steps of: transiting only a real subscriber, subscriber provisioned just before starting the both systems, into a port unblock state; executing an unblock flow of an individual port, referred to the provisioned subscriber; transmitting a request of the full port unblock to a port management task of the AN system, as the control task of the AN system interfaces for a port block/unblock process with a control task of the LE system; detecting a provisioned port, as a port management task tests a subscriber port database; making a start port number and an end port number of a provisioned port interval as a parameter; calling a partial port unblock function defined on a public switched telephone network(PSTN) task of the system(S6); and transiting into the port unblock state, with the PSTN task executing a corresponded routine of the port interval according to the call in the S6.

Description

Subscriber port status management method

The present invention relates to an initial startup flow of an Access Network (AN) system and a Local Exchange (LE) system according to the Integrated Digital Loop Carrier (IDLC) V5.2 protocol, and in particular, all port unblocks. ) Processing method.

1 shows an IDLC V5.2 link configuration, where the AN system 100 and the LE system 102 are connected by an IDLC V5.2 link. The entire port unblock procedure, which is part of this initial startup procedure of the AN system 100 and the LE system 102, is shown as FIG. 2. Referring to FIG. 2, when the AN system 100 transmits an unblock request with common control in step 200 of FIG. 2, the LE system 102 unblocks in step 202. The common control acknowledgment is transmitted according to the request, and the unblocking acknowledgment is transmitted with the common control in step 204. The AN system 100 then transmits a common control ACK according to the unblocking acknowledgment in step 206 and transmits an unblock completion with common control in step 208. The LE system 102 then transmits the unblock completion with common control in step 210. Through the process as shown in FIG. 2, the subscriber state of the AN system 100 and the LE system 102 transitions to an unblocked state.

If it is assumed that the maximum accommodating subscriber of the AN system 100 is 480, the port state of all subscribers corresponding to 480 is changed from the initial block state to an unblocked state through the above process. At this time, a subscriber who is not a real subscriber, that is, a subscriber who is not actually provisioned, is transferred to a serviceable state through the above process. As a result, when an event occurred, the system had an unexpected action. In addition, even though the subscriber port state between the AN system 100 and the LE system 102 must match, there has been a case of mismatch.

As described above, according to the conventional full unblocking procedure, even a subscriber who is not a real subscriber transitions to a serviceable state, thus causing unnecessary actions in the system, and inconsistent subscriber port states between the AN system and the LE system. .

Accordingly, an object of the present invention is to provide a subscriber port management method that can prevent unnecessary actions of the system due to subscribers that are not actually provisioned.

Another object of the present invention is to provide a subscriber port management method that can prevent inconsistency in the subscriber port state between the AN system and the LE system.

1 is an IDLC V5.2 link configuration diagram,

2 is an initial startup procedure between the AN system and the LE system according to the IDLC V5.2 protocol;

3 is a configuration diagram of a task according to an embodiment of the present invention;

4 is a process flow diagram of the port management task of FIG. 3 in accordance with an embodiment of the present invention.

In order to achieve the above object, the present invention provides a first process of transitioning to a port unblocking state only for a real subscriber who is a provisioned subscriber immediately before initial startup between the AN system and the LE system, and for a newly provisioned subscriber. And a second process of performing an unblocking process for each individual port.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

3 illustrates a task configuration diagram of the AN system 100 and the LE system 102 according to an embodiment of the present invention. The control task 302 of the AN system 100 serves as an interface for port block / unblock processing with the LE control task 306 of the LE system 102 and manages port block / unblock requests by port management tasks. Send to 300. The port management task 300, upon receiving a port block / unblock request from the control task 302, checks the subscriber port database to see if it is a provisioned port. In addition, the provisioned port interval is determined and the block / unblock is indicated to the PSTN task 304. The PSTN task 304 transitions to a state in which the port management task 300 instructs only a port which has been assigned a section while performing a corresponding routine.

As shown in FIG. 3, the control task 302 serves as a port block / unblock interface with the LE control task 306, and transmits a message received from the control task 302 to the port management task 300. Done.

At this time, when the port management task 300 receives the entire port unblocking request from the control task 302, the port management task 300 handles FIG. 4 showing a processing flowchart of the port management task 300 according to an embodiment of the present invention. First, in step (400), the actual provisioned subscriber is found. In step 402, the "port unblocking block 100, 300" function is called using the start port number and the end port number as parameters. In this case, the port management task 300 uses the first provisioned port as the start port number and the port obtained by subtracting 1 from the first non-provisioned port as the end port number. That is, for example, in the AN system 100 accommodating 480 subscribers, assuming that the provisioned subscribers are ports 100 to 300, the parameters of the start port number 100 and the end port number 300 are parameters. Done. When some of the port unblock functions defined in the PSTN task 304 are called, the PSTN task 304 executes the corresponding routine. The initial start transitions the port state from 100 to 300 to unblock. Accordingly, out of the total of 480 subscribers, only ports 100 to 300 transition to an unblockable state in which they can be serviced, and block states, which are initially in the initial state, are maintained.

As described above, only the subscribers who are provisioned subscribers immediately before the initial startup between the AN system 100 and the LE system 102 transition to the port unblocked state. Then, the newly provisioned subscriber is unblocked for each port.

Accordingly, in the initial startup procedure between the AN system 100 and the LE system 102, unnecessary action of the system can be prevented by unblocking the subscribers regardless of the maximum subscribers of the AN system 100. In addition, a more stable subscriber service can be achieved by preventing inconsistencies in port state data between the AN system 100 and the LE system 102, which may occur by unblocking ports other than the subscriber.

As described above, the present invention can prevent unnecessary actions of the system by unblocking the subscriber and prevent more inconsistency of the port state data between the AN system and the LE system, thereby providing more stable subscriber service. have.
