Description

Technical Field

[0001] The present invention relates to the field of mobile communications, and in particular to an operation and maintenance method and device for monitoring a link via a remote machine. Background Art

[0002] With the rapid development of network technology and the continuous expansion of network scale, the number of operators' repeater equipment is increasing, and the demand for repeater system monitoring is also increasing. The operation and maintenance terminal (OMT) enables on-site monitoring of repeaters, making it easier for maintenance personnel to debug and maintain.

[0003] Most of the existing solutions are that the operation and maintenance terminal is connected to the access unit (AU), and the access unit (AU) provides data and information relay and forwarding for the operation and maintenance terminal (OMT) and the remote unit (RU). The remote unit (RU) does not communicate directly with the operation and maintenance terminal (OMT), and its communication is forwarded through the access unit (AU).

[0004] A possible problem with such a solution is that when the maintenance personnel have only one remote unit, they cannot monitor this device and other devices in the link through the operation maintenance terminal. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide an operation and maintenance method and device for monitoring a link through a remote machine, so that no matter which device in the link is accessed from the operation and maintenance terminal, the devices in the link can be monitored, thereby improving the efficiency of monitoring the link.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: an operation and maintenance method of monitoring a link through a remote machine, comprising the following steps:

[0007] Step 1: The operation and maintenance terminal OMT is connected to a remote unit RU, and the remote unit RU confirms the target device of the message according to the device number contained in the message sent by the operation and maintenance terminal OMT;

[0008] Step 2: When the operation and maintenance terminal OMT sends a message to the remote unit RU directly connected to it, the remote unit RU receives and processes the message and then sends a reply message back to the operation and maintenance terminal OMT;

[0009] Step 3: When the operation and maintenance terminal OMT message is sent to the access unit AU, the remote unit RU directly connected to the operation and maintenance terminal OMT sets the identification bit in the message to the operation and maintenance terminal OMT message, and then forwards the message to the access unit AU. After processing, the access unit AU sends the message back to the remote unit RU according to the identification bit, and the remote unit RU sends the message back to the operation and maintenance terminal OMT.

[0010] Step 4: When the operation and maintenance terminal OMT message is sent to other devices in the link, the remote unit RU directly connected to the operation and maintenance terminal OMT sets the identification bit in the message to the operation and maintenance terminal OMT message, and then forwards the message to the access unit AU, which then forwards it to the target device according to the device number. After the target device receives and processes it, it sends a reply message back to the access unit AU according to the identification bit, which is then sent back to the remote unit RU by the access unit AU, and then sent back to the operation and maintenance terminal OMT by the remote unit RU.

[0011] Furthermore, in step 1, the operation and maintenance terminal (OMT) is connected to a remote unit (RU) via Ethernet, and the remote unit RU confirms the target device of the message according to the device number contained in the message sent by the operation and maintenance terminal OMT. Specifically, the operation and maintenance terminal OMT sends a message to the target device, queries the device information, and monitors the devices in the link. The message sent is composed according to the protocol and contains information such as the device number, operation type, and operation content. Each device in the link has its own number. According to the device number in the message sent by the operation and maintenance terminal OMT, the remote unit RU can determine which device the message received at this time is for operation.

[0012] Furthermore, the remote unit RU will process the received message according to the situation. If the message is for operating the directly connected remote unit RU, the remote unit RU will complete the corresponding operation according to the message content, compose a reply message according to the protocol, and send it back to the operation and maintenance terminal OMT. The operation and maintenance terminal OMT now completes the monitoring process of the directly connected remote unit RU.

[0013] The access unit AU is the center of the link, and multiple remote units RU can be connected to it. When the remote unit RU directly connected to the operation and maintenance terminal OMT receives a message, if the device number is different from this remote unit RU, the remote unit RU needs to forward the message to the access unit AU. The identification bit is included in the message to distinguish the message type. The access unit AU parses the device number in the message to determine which device the message is sent to.

[0014] If the message is from the operation access unit AU itself, then after the access unit AU completes the corresponding operation according to the message content, it forms a reply message according to the protocol, sends the message back to the remote unit RU according to the identification bit, and the remote unit RU forwards it back to the operation and maintenance terminal OMT. The operation and maintenance terminal OMT now completes the monitoring process of the access unit AU.

[0015] If the message is from other remote units RU in the operation link, the access unit AU forwards the message to the target remote unit RU after receiving it; after the target remote unit RU completes the corresponding operation according to the message content, it forms a reply message and sends it back to the access unit AU according to the identification bit; the access unit AU then sends it back to the remote unit RU directly connected to the operation and maintenance terminal OMT, which forwards it back to the operation and maintenance terminal OMT. At this time, the operation and maintenance terminal OMT completes the monitoring process of other remote units RU in the link.

[0016] The present invention also provides a device applicable to the above-mentioned operation and maintenance method of monitoring a link through a remote machine, comprising a message parsing module and a message forwarding module:

[0017] Message parsing module: The remote unit RU directly connected to the operation and maintenance terminal OMT parses the message sent by the operation and maintenance terminal OMT after receiving it, and parses out the required information, including device number, operation type, operation content, etc. In the case of forwarding the message, the identification bit in the message is set to the operation and maintenance terminal OMT message, indicating that the message is sent to the link by the operation and maintenance terminal OMT through the remote unit RU, and needs to be sent back to the operation and maintenance terminal OMT.

[0018] Message forwarding module: When a device receives a message that is not intended for its own operation, it forwards it to the corresponding device based on the device number and identification bit.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. According to the method and apparatus provided by the present invention, the operation and maintenance terminal can be connected through any device in the repeater system to monitor the repeater system, thereby solving the problem that the personal computer (PC) is only near one remote unit RU and is too far away from other devices to monitor other devices in the link;

[0021] 2. The present invention cooperates with the message forwarding module and the message parsing module. No matter which device in the link the operation and maintenance terminal accesses from, it can send messages to any device in the link, successfully communicate with the entire link, and realize monitoring of the entire repeater system, which is convenient for maintenance personnel to monitor and debug.

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are given in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0029] In order to better explain the present invention, Figure 1 , the operation and maintenance terminal (OMT) is connected to a remote unit (RU1) through Ethernet to access the repeater system. In the repeater system, the access unit AU is the center of the link, and multiple remote units RU can be connected to it, such as Figure 1 The remote units RU1 and RU2 in the.

[0030] The message composition of the communication between the operation and maintenance terminal and the repeater system is as follows: Figure 2 As shown, the message includes a device number, a message identifier, an operation type, and an operation content. The device number in the message is the number of the device in the repeater system. Each device has a unique number, and the device number can be used to confirm which device the message is sent to. The message identifier is used to distinguish the type of message and identify where the message is sent from. In the present invention, the message identifier is set to identify that the message is sent by the operation and maintenance terminal OMT to monitor the link. The operation type and operation content in the message are specific operations on the monitoring device.

[0031] After the operation and maintenance terminal accesses the link, it sends a monitoring message to the link. After receiving the message, the remote unit RU1 first parses the device number in the message to confirm the target device of this message.

[0032] If the parsed device number is the number of remote unit RU1, combined with Figure 3 , the remote unit RU1 continues to parse the operation type and operation content of the message and completes the corresponding operation. After completing the instruction sent by the operation and maintenance terminal OMT, a reply message is sent back to the operation and maintenance terminal OMT, thereby completing the monitoring of the remote unit RU1 by the operation and maintenance terminal OMT.

[0033] If the parsed device number is not the number of the remote unit RU1, the remote unit RU1 continues to set the message identifier as an operation and maintenance terminal OMT message, and then sends the message with the set identifier to the access unit AU. After receiving the message, the access unit AU parses the device number in the message and compares it with its own device number. The results are divided into the following two situations:

[0034] The first type is that the parsed device number is the number of the access unit AU, combined with Figure 4 The access unit AU continues to parse the operation type and operation content of the message and completes the corresponding operation. After completion, the reply message is sent back to the remote unit RU1 according to the identifier, and the remote unit RU1 restores the message identifier and sends it back to the operation and maintenance terminal OMT.

[0035] The second type is that the parsed device number is not the number of the access unit AU, but the device number of the remote unit RU2. Figure 5 , the access unit AU sends the message to the remote unit RU2 connected to it. After receiving the message, the remote unit RU2 also parses the message identifier, operation type and operation content. After completing the corresponding instructions, it sends a reply message to the access unit AU according to the message identifier, and the access unit AU sends it back to the remote unit RU1. After receiving the reply message, the remote unit RU1 restores the set identifier and sends it back to the operation and maintenance terminal OMT.

[0036] In particular, if the parsed device number is the number of remote unit RU3, combined with Figure 6 The message forwarding process is the same as that of the remote unit RU2. The intermediate forwarding is implemented by the access unit AU and does not need to pass through the remote unit RU2.

[0037] In order to implement the parsing and forwarding of the above-mentioned messages, the embodiment of the present invention also proposes a device for monitoring the operation and maintenance of a link through a remote machine. The device includes a message parsing module and a message forwarding module;

[0038] The message parsing module is used to parse the message sent to the repeater system. After the message parsing module, various information in the message can be read by the repeater device. In the present invention, when the message is sent from the operation and maintenance terminal OMT to the repeater system, the remote unit RU1 directly connected to the operation and maintenance terminal OMT first parses the device number, and confirms whether the message needs to be forwarded to other devices according to the device number.

[0039] If forwarding is not required, the operation type and operation content are further parsed to complete the instruction of the operation and maintenance terminal OMT; if forwarding is required, the identification bit is further parsed and the identification bit is set as the operation and maintenance terminal OMT message and sent to the access unit AU through the message forwarding module.

[0040] Similarly, the access unit AU also first parses the device number to determine whether the message needs to be forwarded. Unlike the remote unit RU1, if the message needs to be forwarded, just retain the identification bit set by the remote unit RU1 and forward it to the target device through the forwarding module without the need to set the identification bit.

[0041] The identification bit is only set or restored by the remote unit RU1 directly connected to the operation and maintenance terminal OMT to ensure the correctness of the message during transmission and avoid confusion in message transmission.

[0042] The message forwarding module is used to forward messages that are not operated by the repeater system. Through the message forwarding module, the operation and maintenance terminal OMT can monitor the equipment in the entire repeater system. When the message of operating the access unit AU is sent from the operation and maintenance terminal OMT to the remote unit RU1, the remote unit RU1 can forward the message to the access unit AU, so that the operation and maintenance terminal OMT successfully communicates with the access unit AU, and the operation and maintenance terminal OMT monitors the access unit AU.

[0043] When the message of other remote units RU in the operation link is sent from the operation and maintenance terminal OMT to the remote unit RU1, the remote unit RU1 can forward the message to the access unit AU. The access unit AU can forward the message to other remote units RU connected thereto according to the parsed device number.

[0044] Through the cooperation between the message forwarding module and the message parsing module, the operation and maintenance terminal can send messages to any device in the link no matter which device in the link it is connected from, successfully communicate with the entire link, realize the monitoring of the entire repeater system, and facilitate the monitoring and commissioning of maintenance personnel.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
