In such an optical relay system, each remote optical repeater installed at a long distance (for example, about 2 km) through an optical path is directly exposed to the external environment, causing an output change of about 7 dB according to temperature change.

However, in the conventional optical repeater system, since there is no control path between the master optical repeater and the remote optical repeater, when the state change of the optical repeaters according to the temperature change occurs, the base station operator directly goes to the remote optical repeater and separate measurement equipment ( For example, notebook PC) had to be managed.

Therefore, the base station operator should go to the place where the remote optical repeater is connected whenever necessary and connect the PC to the control port of the remote optical repeater to find out the status, and also if the large power amplifier is disabled during the operation of the optical repeater. There is a problem that an operator cannot give an enable command by a man-machine command (MMC).

Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a state flowchart of a state management message sent from a radio frequency controller, and is based on the configuration of the optical relay system, that is, the base station system shown in FIG.

Referring to FIG. 2, in the optical relay system, the radio frequency controller requests a state according to a protocol address between the radio frequency controller and the optical repeaters defined as a polling period of 40 seconds to control the state change of the optical repeaters according to an external temperature change. The message is sent to a master optical processor controller (hereinafter referred to as MOPA) or a remote optical processor controller (hereinafter referred to as ROPA) (S200).

At this time, the radio frequency controller checks the state of the optical path between the MOPA and ROPA, and sends a status request message to the MOPA if the optical path is normal.

The optical repeater status manager of the status request message composed of software performs the following functions as part of an application program used in the radio frequency controller.

(1) State management function: The polling cycle has the following functions.

-Status management of operating devices: Whenever there is a change in each device, the RF controller takes care of it.

That is, state management for RF modems, E-O converters, pre-amps and distributors as MOPA devices, and RF modems, O / E converters, attenuators, thermometers, and high-power amplifiers as ROPA devices. ), Low noise amplifier (LNA), power detector, and BTU state management.

Periodic reporting status management: Update status at regular intervals regardless of the status change of each device.

That is, it has a state management function for the MOPA device and a state management function for the ROPA device.

(2) Large power amplifier control function: If the base station operator wants to stop the service of the corresponding optical repeater, the base station manager can send the HPA Disable command by the MMC to stop the service of the specific optical repeater. You can send a command to start the service of a specific optical repeater.

(3) Upper processor reporting function: reports the state detected by the radio frequency controller to the base station processor (BSP), and the base station processor reports to the base station manager. Thus, the operator can control all optical repeaters from the central control station of the base station.

(4) Processor keep-alive function: The radio frequency controller sends a status request message to the MOPA and ROPA, and if there is no response message for 5 or more consecutive times, the status of the processor is regarded as abnormal and is reported to the base station processor which is the upper processor. do.

And, the ROPA receiving the status request message of the radio frequency controller having such a function is a processor in charge of one remote optical repeater, and in the base station system, up to four remote optical repeaters including ROPA are provided to each master optical repeater. Since up to 12 remote optical repeaters can be connected to one base station system (optical relay system).

In addition, the status request message sent to the MOPA or ROPA is configured as shown in Table 1.

The state measurement command message thus constructed will be described.

Referring to Table 1, an address byte consisting of one byte is configured as shown in Table 1a below.

D ₇ ⁰ D ₆ ⁰ D ₅ ⁰ D ₄ ⁰ D ₃ ⁰ D ₂ ⁰ D ₁ ⁰ D ₀ ⁰

Where D₀ ⁰, D_One ⁰, D₂ ⁰Bit is the ROPA select bit, D₃ ⁰Is the ROPA ignore bit. Also D₄ ⁰, D₅ ⁰, D₆ ⁰Is the select bit of sector E / O in MOPA, and D₇ ⁰Is the Reserved bit.

Therefore, if the D ₃ ⁰ bit is '1', the address for ROPA is ignored and the MOPA sends the radio frequency controller the status for the selected E / O converter (or all E / O converters).

An example of the use of these address bytes is shown in Table 1aa below.

D ₇ ⁰ D ₆ ⁰ D ₅ ⁰ D ₄ ⁰ D ₃ ⁰ D ₂ ⁰ D ₁ ⁰ D ₀ ⁰ Justice × × × × 0 0 0 0 Choose ROPA # 0 × × × × 0 0 0 One Choose ROPA # 1 × × × × 0 0 One 0 Choose ROPA # 2 × × × × 0 0 One One Choose ROPA # 3 × × × × 0 One One One Select all ROPAs × × × × One 0 0 0 Ignore ROPA 0 0 0 0 × × × × E / O alpha selection 0 0 0 One × × × × E / O Beta Selection 0 0 One 0 × × × × E / O Gamma Selection 0 One One One × × × × Select all E / Os 0 0 0 0 × × × × Set to '0'

In addition, the instruction byte consisting of 1 byte shown in Table 1 is shown in the following Table 1b.

D ₇ ¹ D ₆ ¹ D ₅ ¹ D ₄ ¹ D ₃ ¹ D ₂ ¹ D ₁ ¹ D ₀ ¹

Where D₀ ^OneIs the MOPA status request instruction bit, and D_One ^OneIs the ROPA status request command bit. Also, D₂ ^OneIs the transmit attenuation command bit, D₃ ^OneIs the status measurement start command bit of the optical repeater and D₄ ^One, D₅ ^One, D₆ ^One, D₇ ^OneIs the default baud rate bit.

On the other hand, among the command bytes, an HPA enable / disable command is periodically sent to the ROPA, which responds with a device status message, and responds with a designated response message for other commands.

Then, the radio frequency controller sends only one type of command message to the MOPA or ROPA in one command message.

An example of such an instruction byte is shown in Table 1BA below.

D ₇ ¹ D ₆ ¹ D ₅ ¹ D ₄ ¹ D ₃ ¹ D ₂ ¹ D ₁ ¹ D ₀ ¹ Justice 0 0 0 0 0 0 0 One MOPA status request 0 0 0 0 0 0 One 0 ROPA status request 0 0 0 0 0 One 0 0 Transmit attenuation 0 0 0 0 One 0 0 0 Start status measurement 0 One 0 0 0 0 0 0 Voltage standing wave measurement at basic transmission speed

If the command byte is 0x02 (ROPA status command), the data byte is referred to.

The data byte shown in Table 1 is configured as shown in Table 1c below according to the command byte, and the ROPA command is configured as shown in Table 1ca.

Referring to Table 1ca, the radio frequency controller takes action on the DCA only when the Over Power Alarm is detected on the DCA (other alarms have an automatic recovery function).

In this case, the action is to continuously give Disable and Enable commands to the DCA.

Therefore, when the ROPA receives the defined data, the ROPA will take this action in succession with the DCA. The data defined here are '0x1 ×' and '0x2 ×' and the lower 4 bits are Don't Care bits and are controlled by the upper 4 bits.

The cyclic redundancy check (CRC) byte shown in Table 1 is generated by X ¹⁶ + X ¹² + X ⁵ +1, which is a polynomial according to the CRC-CCITT-16 standard, and the last flag is a value of 0x7E. Is set.

MOPA receiving the status request message of the RF controller configured as described above transmits the status of each device (E / O converter, RF modem, Pre-Amp, distributor) that it manages to the RF controller (S201).

At this time, the status response message of the MOPA is configured as shown in Table 2 below.

MOPA Response Message Format byte name Justice 0 Address response Address copy byte One Command response Instruction copy byte 2 Alpha DACA DACA fault table 3 Alpha MOTA MOTA fault table 4 Alpha MOSA MOSA fault table 5 Beta DACA DACA fault table 6 Beta MOTA MOTA fault table 7 Beta mosa MOSA fault table 8 Gamma DACA DACA fault table 9 Gamma MOTA MOTA fault table 10 Gamma MOSA MOSA fault table 11 Modem status Modem fault table 12, 13 CRC CRC byte 14 flag Last flag

Referring to Table 2, the address response byte is copied as it is to the address byte of Table 1a. At this time. The radio frequency controller compares the address response byte to determine whether it is a response to the address sent by the radio frequency controller.

And. The command response byte is also copied as the command byte of Table 1b.

Then, the router function implemented in software in the radio frequency controller examines this byte and distinguishes whether it is in response to a command sent by an HPA task or a command sent by a BTU task and routes it to each task.

In addition, the CRC byte and the last flag are the same as in Table 1.

Meanwhile, the HPA Enable / Disable command is also sent to the status request message sent periodically by the RF controller.

The radio frequency controller sends a status request message to the MOPA and each ROPA at each polling period. If there is no response message five or more times in succession, the radio frequency controller regards the status of the processor as abnormal and stops managing the status of the processor. do.

3 is a flowchart illustrating a communication procedure between an RF controller and an optical repeater.

Referring to FIG. 3, a communication procedure between the radio frequency controller and ROPA will be described as an example.

First, the radio frequency controller sends a status request message to the ROPA (S300).

The radio frequency controller waits for a response message from the ROPA, and determines whether a response message is coming (S301).

In response to receiving the response message, it is again determined whether the ROPA state measurement result data is coming (S302), and when the determination result is received, the response time is set to '0' (S303).

Subsequently, the values of the previous state and the current state of the devices managed by the ROPA are compared (S304). If the state is the same as the determination result, the process returns to the initial state and waits for a status request message (S305).

However, if it is determined that the previous state and the current state are different, the state of each device is updated (S306), and the updated state is reported to the upper processor together with the warning sound of the base station processor (S307).

On the other hand, as a result of the determination in step S301, if the response message has not come from the ROPA, while waiting for the response message increases the waiting for the response message of the ROPA (S308).

When the response time is measured and expressed as the number of times, the response message is not compared more than five times (309). If the response is not determined more than five times, it is regarded as an abnormality of each device of the ROPA and the processor state. Update (S310).

Next, the updated status is reported to the upper processor together with the warning sound of the base station processor (S311).

However, if the response comes from ROPA before the response time increases more than five times, it substitutes the current state for the previous state and saves it and waits for the status request message.

From step S309 to step S311 is to display the wrong state of the ROPA receiving the status request message and to inform the upper processor.

As described above, the present invention provides a state management method of the optical repeater, so that the base station operator can monitor and control the state management and DCA operation of the current optical repeater without going out and measuring directly with the optical repeater installed at a long distance. In addition, there is an effect that can know the status of the current optical repeater whenever necessary.
