METHOD FOR CONTROLLING COMMON CONTROL MESSAGE USING V5.2 COMMON PROTOCOL IN WLL SYSTEM}

The present invention relates to a method of controlling a COMMON control message using a 5.2 COM protocol in a wireless local loop (WLL) system. More specifically, the WLL exchange allows a WLL exchange to subscribe to a COMMON control message. In the PLC system that checks whether the COMMON control response message is received from the subscriber device when transmitting to the device, and performs the transmission operation sequentially, the subscriber port management and V5.2 protocol stack restart management work can be performed smoothly. Ｖ5.2 COMOMON protocol relates to a method for controlling a COM control message.

As is well known, the V5.2 protocol of the WLL exchange consists of the Public Switched Telephone Network (PSTN) protocol, the Bearer Channel Control (BCC) protocol, the COMMON protocol, the Link protocol, and the Protection protocol. Among them, the COMMON protocol to which the present invention corresponds is a function for managing a plurality of subscriber ports and managing restart of the V5.2 protocol stack. Here, the management of restarting the V5.2 protocol stack described above means initialization of the V5.2 protocol.

In the conventional PLC system, the CO2 control message transmission / reception method using the 5.2 COMMOON protocol is performed. When the COMMON control message transmission request signal is received from the system operation / management unit, the COMMON protocol processing unit in the WLL exchange generates a COMMON control message. Send to the subscriber device. Then, after receiving the COMMON control message transmitted from the COMMON protocol processor, the subscriber device transmits the COMMON control response message corresponding to the COMMON control message to the COMMON protocol processor again. Accordingly, subscriber port management between the WLL switch and the corresponding subscriber device and management of restarting the V5.2 protocol stack are normally performed.

However, in the COL control message transmission / reception method using the # 5.2 COMMOON protocol in the conventional PLC system described above, when the COMMON control message transmission request signal is received from the system operation / management unit, the COMMON protocol processing unit receives the COMMON from the subscriber device. Regardless of whether or not the control response message is received, it is difficult to check whether the transmission of the COMMON control message to the subscriber device is normally performed by unconditionally sending the COMMON control message to the corresponding subscriber device. In addition to not maintaining the system efficiently, the common control message is frequently lost during transmission.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to efficiently manage COMMON control messages, thereby preventing the loss of COMMON control messages, thereby preventing normal WLL exchange and corresponding subscribers. The present invention provides a method of controlling a COMMONE control message using a G5.2MOMMON protocol in a WL2 system to enable management of subscriber ports between devices and management operations when the V5.2 protocol stack is restarted.

In order to achieve the above object, the COM control message control method using the 5.2 COM protocol in the present invention is a WLL exchanger including a system operation / management unit, a COMMON protocol processing unit, and a level 2 protocol processing unit; In a COLM control message control method using a 5.2 COMMON protocol in a PLC system having a plurality of subscriber apparatuses, the COMMON protocol processor determines whether a COMMON control message transmission request signal is received from a system operation / management unit.

And a queue-count area 1213-4 which stores information on the total number of COMMON queues 1211a in which the COMMON control messages are stored.

Meanwhile, when the COM5.2 V5.2 entity 1220 installed in the COMMON protocol processing unit 1200 of the WLL exchanger 1000 receives a COMMON control message transmission request signal from the system operation / management unit 1100, FIG. It plays a role of generating COMMON control message as shown.

At this time, as shown in FIG. 4, the above-described COMMON control message includes a protocol identification area of 1 byte, a port-ID of 2 bytes of level 3 address, a message type of 1 byte, a control function ID of 3 bytes, and a byte of 1 byte. It consists of unique ID information (Variant_ID) of the V5.2 entity 1220 for COMMON.

In addition, the level 2 protocol processing unit 1300 installed in the WLL switch 1000 receives a COMMON control message output from the COMMON protocol processing unit 1200 and at the same time the COMMON control message is controlled by the control station 1 and the base station ( 2) when the COMMON control response message outputted from the subscriber apparatus 2000 is input via the control station 1 and the base station 2, the COMMON control response message is transmitted to the corresponding subscriber device 2000.

At this time, as shown in FIG. 5, the above-described COMMON control response message is composed of a protocol identification area of 1 byte, a port-ID which is a level 3 address of 2 bytes, a message type of 1 byte, and a serial number of 3 bytes.

Next, a method of controlling a COMMON control message using the # 5.2 COMMON protocol in the GLM system according to an embodiment of the present invention will be described below using the above-described apparatus.

FIG. 7 is an operation flowchart illustrating a method of controlling a COM control message using the # 5.2 COMMON protocol in the GLM system according to an embodiment of the present invention.

First, the COMMON protocol processor 1100 mounted in the WLL switch 1000 determines whether a COMMON control message transmission request signal is received from the system operation / management unit 1100 (S1).

At this time, when the COMMON control message transmission request signal is received from the system operation / management unit 1100 in the first step S1 (YES), the V5.2 entity 1220 for COMMON in the COMMON protocol processing unit 1100 is COMMON. Generate a control message (S2).

Thereafter, the COMMON protocol processing unit 1200 is stored in the COMMON protocol transmission state storage area 1213-1 and the queue-count area 1213-4 in the COMMON queue management table 1213, as shown in FIG. Using the information, it is determined whether the current COMMON protocol transmission state is in a transmittable state, in a transmit standby state, or in a non-transmissible state (S3). At this time, when 'LE ₀ ' is written in the COMMON protocol transmission state storage area 1213-1 of the COMMON queue management table 1213, the COMMON protocol transmission state indicates a state that cannot be transmitted, and the COMMON queue management table 1213 If 'LE ₁ ' is written in the COMMON protocol transfer status storage area 1213-1 of the table and '0' count is written in the queue-count area 1213-4, the COMMON protocol transfer status indicates the transferable state. 'LE ₂ ' is described in the COMMON protocol transmission state storage area 1213-1 of the COMMON queue management table 1213, and the count value of the queue-count area 1213-4 is '0'. Otherwise, the COMMON protocol transmission status indicates the transmission standby status.

On the other hand, if the current COMMON protocol transmission state is the transmission standby state in the third step (S3), the COMMON protocol processing unit 1200 as shown in Fig. 2, the unused queue-front in the unused queue management table 1212 Using the information stored in the storage area 1212-1 and the total number of unused queue-number storage area 1212-3, the first COMMON queue 1211a currently in use is selected (S4).

Thereafter, the COMMON protocol processing unit 1200 generates the first unused COMMON in the COMMON control message storage table 1211, as shown in FIG. 2, of the COMMON control message generated by the V5.2 entity 1220 for COMMON. The data is stored in the queue 1211a (S5).

Subsequently, the COMMON protocol processing unit 1200 stores ID information of the first COMMON queue 1211a and ID information of the last COMMON queue 1211a among the plurality of COMMON queues 1211a in which the COMMON control messages are stored. After storing in the queue-front storage area 1213-2 and the queue-end storage area 1213-3 of 1213, the COMMON queue count value stored in the queue-count area 1213-4 is counted as '1'. Increase (S6).

On the other hand, the COMMON protocol processor 1200 determines whether a COMMON control response message is received from the subscriber device 2000 (S7).

In this case, when the COMMON control response message is not received from the subscriber station 2000 in the seventh step S7 (NO), the COMMON protocol processing unit 1200 proceeds to the first step S1 again. When the COMMON control response message is received from the subscriber device 2000 (YES), the COMMON protocol processing unit 1200 uses the information of the queue-front storage area 1213-2 in the COMMON queue management table 1213. The first COMMON queue 1211a in which the COMMON control message is stored is selected from the plurality of COMMON queues 1211a in the control message storage table 1211 (S8).

Thereafter, the COMMON protocol processor 1200 reads the COMMON control message stored in the first COMMON queue 1211a in use and outputs the same to the level 2 protocol processor 1300. Then, as shown in FIG. 6, the level 2 protocol processing unit 1300 receives a COMMON control message output from the COMMON protocol processing unit 1200 and receives the corresponding subscriber station through the control station 1 and the base station 2. The apparatus 2000 transmits to the device 2000 (S9).

Subsequently, the COMMON protocol processor 1200 changes the information of the queue-front storage area 1213-2 and the queue-end storage area 1213-3 in the COMMON queue management table 1213, and at the same time, queue-count. The common queue count value of the area 1213-4 is decremented by '1' and then returned (S10).

On the other hand, if the COMMON control message transmission request signal is not received from the system operation / management unit 1100 in the first step S1 (NO), the COMMON protocol processing unit 1200 proceeds to the seventh step S7 again. do.

In addition, if the current COMMON protocol transmission state is in a non-transmissible state in the third step S3, the COMMON protocol processing unit 1200 terminates after performing a transmission error process (S11).

On the other hand, if the current COMMON protocol transmission state is a transmittable state in the third step S3, the COMMON protocol processing unit 1200 generates a COMMON control message generated by the V5.2 entity 1220 for COMMON in the level 2 protocol. After outputting to the processing unit 1300, the process proceeds to the seventh step S7 again (S12). Then, the level 2 protocol processing unit 1300 receives the COMMON control message output from the COMMON protocol processing unit 1200, as shown in FIG. 6, through the control station 1 and the base station 2. Transmit to device 2000.

As described above, according to the COMMON control message control method using the 5.2 COMMON protocol in the GL system according to the present invention, when a WLL exchange sends a COMMON control message to a subscriber device, it receives a COMMON control response message from the subscriber device. By checking whether or not the transmission operation is performed sequentially, the maintenance of the common control message can be more efficiently performed, and thus, the loss of the common control message can be prevented, thereby preventing subscriber port management and V5.2. Resuming the protocol stack has a great effect on the smooth management.
