Description

Method and device for processing TR-069 message

Technical field

The present invention relates to the field of communications, and in particular, to a method and apparatus for processing a TR-069 message.

Background technique

The automatic configuration server (Auto Config Server, ACS for short) is configured as the management of the Customer Premise Equipment (CPE) network. It manages the configuration, diagnosis, and performance collection of the terminals that support TR-069. User-side device CPE refers to hardware that is physically located at the user layer, such as: servers, workstations, communication hardware (CSU/DSUs, modems), LAN devices (hubs, bridges, switches), WAN devices (routers), including but not Limited to Digital Subscriber Line Modem (DSL Modem), Gigabit-Capable Passive Optical Network (GPON) and Ethernet Passive Optical Network (Ethernet Passive Optical Network) EPON) Uplink Optical Network Unit (ONU), Interactive Internet TV IPTV Set Top Box, OTT (Over The Top) Set Top Box, Acess Poinit (AP), Integrated Access Equipment IAD et al. Generally, the number of CPEs managed by a set of ACS is huge, and the number can even exceed 10 million. The CPE device is from different vendors, different versions of different batches, some devices appear in the network, or individual batch devices work abnormally and send abnormal packets to the ACS, or send a large number of packets to the ACS because of device configuration problems. Because there are a large number of terminals on the network, even if a small number of devices fail, a large number of packets will be generated. These abnormal packets will occupy network bandwidth, affect normal packet transmission, and consume ACS processing resources. The services that the ACS needs to process cannot be successfully completed. This can greatly affect the normal management operations of the ACS. The management services become slower or even the management services fail. This affects the normal management of the entire network. At present, the general ACS system uses the load balancing device to process some abnormal or invalid packets through the pre-load balancing device. However, since the load is an independent device or component, it can only be processed according to some simple rules. Complex scenarios of various types of abnormal or invalid packets have limited effect; they cannot suppress the generation of such invalid traffic in the network, thereby reducing bandwidth resource consumption and improving bandwidth utilization.

In the related art, when a CPE device is faulty or abnormal, a large number of invalid or abnormal packets are reported, which consumes network bandwidth, affects normal packet transmission, and consumes ACS processing resources, which has a great impact on the normal management operation of the ACS.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the embodiment of the present invention, a method for processing a TR-069 message is provided. FIG. 1 is a flowchart according to an embodiment of the present invention. As shown in FIG. 1, the process may include the following steps:

Step S100: Obtain a TR-069 packet, where the TR-069 packet is from a CPE device;

Step S102: If the TR-069 packet is an abnormal packet, determine whether the CPE device is faulty.

Step S104, processing the TR-069 message according to the determination result.

Unless otherwise stated, the following messages and messages are conceptually the same and do not distinguish. In an ACS network, because a large number of TR-069 packets are reported by tens of thousands of CPE devices, even if a small number of CPE devices fail or fail, a large number of invalid or abnormal TR-069 messages will appear. . These abnormal, invalid, or defamatory packets will occupy the network bandwidth, affecting the normal packet transmission, and consuming the processing resources of the ACS. As a result, the services that the ACS needs to process cannot be successfully completed, which has a great impact on the normal management operations of the ACS. The management business is slow or even the management service is invalid, which affects the normal management of the entire network. Generally, the ACS system uses the load balancing device to process some abnormal or invalid packets through the pre-load balancing device. However, since the load is an independent device or component, it can only be processed according to some simple rules, and cannot handle complicated ones. Scenes of various types of abnormal or invalid messages cannot suppress the generation of such invalid traffic in the network, so the effect is limited. In this embodiment, the selective policy pre-processing of the TR-069 packet message is performed, and the normal packet is directly transmitted to the AC, the abnormal or invalid packet is directly discarded, and the CPE alarm information can be repaired or reported, thereby reducing the invalid message occupation. The network bandwidth, bandwidth consumption, bandwidth utilization, and ACS resources can be effectively used for management service processing, ensuring smooth operation of the ACS system and improving the management stability and effectiveness of the CPE network.

A method for processing a TR-069 message is also provided in the embodiment of the present invention. FIG. 2 is a flowchart according to an embodiment of the present invention. As shown in FIG. 2, the process may include the following steps:

Step S200: Obtain a TR-069 packet, where the TR-069 packet is from a CPE device.

Step S202, determining whether the TR-069 packet is a normal packet;

Step S204: If the TR-069 packet is an abnormal packet, determine whether the CPE device is faulty.

Step S206, processing the TR-069 message according to the determination result.

In a preferred embodiment, in order to save the resources and report the TR-069 message to the ACS in real time, the method in this embodiment may further include: in the case that the TR-069 message is determined to be a normal message, The TR-069 message is transmitted to the ACS.

In a preferred embodiment, processing the TR-069 message according to the determination result may further include: sending a teardown command to the CPE device if the determination result indicates that the CPE device does not fail, wherein the teardown command Used for the CPE device to tear down this session. During the operation of the CPE device, some occasional faults or defects occur, and some abnormal packets or packets that cannot be processed by the ACS are reported. When an abnormal or invalid TR-069 message is detected, it is determined that the CPE only occasionally reports invalid or abnormal messages, which may belong to the message conversion process. Abnormal. We can think that the CPE device has no faults or problems. For these few invalid or abnormal messages, we can directly reply the CPE device with a command to dismantle the session. We can send a TR-069 empty message to end the session.

In a preferred embodiment, processing the TR-069 message according to the determination result may further include: determining, in a case that the CPE device is faulty, determining whether the CPE device can be restored to a normal state by using a remote control command. . A large number of abnormal or invalid TR-069 message messages were detected, and it was determined that the CPE device reporting the abnormal or invalid message had a fault or problem. Discard these abnormal or invalid fault messages directly, and the system can try to repair the faulty CPE device. One way is to use a remote control command to return it to normal operation.

Further, the method may further include: sending a management instruction to the CPE device if the CPE device can be restored to a normal state by using a remote control command, wherein the management command is used to restore the CPE to a normal state. Alternatively, in the case that the CPE device cannot be restored to the normal state by the remote control command, the alarm information is reported, wherein the alarm information is used to indicate that the CPE device is faulty.

After the abnormal packet is identified, the following operations are performed to determine whether the CPE device has a problem: if there is no fault, the spoke is abnormal, and the direct reply message is sent to the cpe to dismantle the session; if the CPE is already in an abnormal working state, it is required. Determine if the CPE can be restored to the normal state by remote control commands. If possible, the CPE is restored to the normal state by sending a management command; if the CPE cannot recover by the remote command, the system generates an alarm to form a work order, and the operator arranges manual troubleshooting. After the above processing, the abnormal state device in the network can be effectively determined, and the device is restored to normal, thereby reducing the total transmission of invalid packets in the network and improving the effective utilization of the network.

In a preferred embodiment, determining whether the TR-069 message is a normal message may further include: extracting a CPE identity attribute and a TR-069 event number attribute in the TR-069 message, and receiving the TR-069 Whether the period of the TR-069 packet sent by the same CPE device reaches the threshold is determined according to the CPE identifier attribute, the TR-069 event number attribute, and the time when the TR-069 packet is received. .

Further, the method may further include: transparently transmitting the TR-069 message to the ACS if the period does not reach the threshold. Alternatively, if the period reaches the threshold, it is determined whether the CPE device has received the repair command.

In the actual deployment, the CPE cycle reporting interval is short due to the failure of the CPE device itself or the default configuration provided by the CPE device. This situation is called the Rampage state. For example, there are 1 million CPEs in the network. The periodic reporting interval is 60 seconds, so even if the CPE online rate is only 40%, then the average value of the message may be 10,000 / sec, and the peak value is as high as 2-3 million per second. In this case, ACS It may not work stably because it cannot be processed. Obtain the reported TR-069 packet message, and extract the CPE device attribute, the TR-069 event number attribute, and the time of receiving the TR-069 message. It is determined whether the TR-069 packet is originated from the same CPE device according to the CPE device attribute and the TR-069 event number attribute, and compares the message messages reported from the same CPE device to determine whether the frequency of the message reported by the CPE device is too high. If the CPE device reports the TR-069 packet message frequency exceeding the preset threshold for a certain reason, it searches for the maintenance record of the CPE device to determine whether it has received the recovery command and sets the reporting period to be lower than the threshold.

Further, if the CPE device does not receive the repair command, the reset command is sent to the CPE device, where the reset command is used to set the period for sending the TR-069 message by the CPE device to a reasonable time; Alternatively, the alarm information is generated when the CPE device receives the repair command. If the CPE device has not been restored, it can be considered that the CPE device has a recent problem, and the period for reporting the reported message is a reasonable time. If the CPE device has been subjected to maintenance, the CPE device has a serious problem. You can use the reset command to restore the system to the normal reporting period. You can add the device to the manual intervention list or alarm or generate a work order or notify the ACS to upgrade the CPE.

In a preferred embodiment, determining whether the TR-069 message is a normal message may further include: configuring one or more valid TR-069 event lists; determining, according to the valid TR-069 event list, whether the TR-069 message is The invalid message includes at least a message that the ACS cannot recognize, and an Inform message that the ACS does not need to process. Generally, there are two cases of invalid messages appearing in a CPE network. One is an unrecognizable message, such as a continuous empty packet, a device-defined Inform message that is not in the operator's specification, and the like; the other is clear Know the Inform messages that you don't need to process. By setting a whitelist or blacklist, for example, a valid TR-069 event list, it is determined by black/white whether the message transmitted by the CEP device is an invalid message.

Further, the method may include: transparently transmitting the TR-069 message to the ACS if the TR-069 message is a valid message; or, if the TR-069 message is an invalid message, Sending a teardown command to the CPE device, wherein the teardown command is used by the CPE device to tear down the session. Different processing is performed on the CPE to report a large number of invalid messages, and it is determined that the valid message can be directly transmitted to the ACS; for the invalid message, the empty message can be restored to end the session, and the preferred embodiment can intercept the invalid message outside the ACS. Avoid consuming ACS resources.

FIG. 6 is a flowchart of a method for processing a TR-069 message according to a preferred embodiment of the present invention; as shown in FIG. 6, the method may include the following process:

Step S600: Acquire a TR-069 message reported by the CPE device; the CPE device sends a TR-069 message to the ACS. The device provided by the preferred embodiment of the present invention, the message pre-processing module obtains the reported message.

Step S602: Determine whether the TR-069 packet is a normal packet. Before reporting the TR-069 packet to the ACS, the message pre-processing module invokes the policy module to determine the packet. If it is not a normal message, the session needs to be dismantled, discarded, or even further repaired by the CPE device.

Step S604, if the TR-069 message is a normal message, transparently transmitting the TR-069 message to the ACS;

In the CPE management network, when a part of the CPE device is in the Rampage state, a large number of reported TR-069 packets are processed as an example, which is described with reference to FIG. 7. First, explain what the CPE device is in the Rampage state. During the actual deployment of the CPE and the ACS network, the CPE device has a relatively high interval due to the failure of the CPE device itself or the default reporting period provided by the CPE device. The frequency reports the TR-069 packet to the ACS. This situation can be called the CPE device in the Rampage state. For example, there are 1 million CPE devices in the network, and the periodic reporting interval is 60 seconds. Even if the online rate of CPE equipment is only 40%, the average value of the message may be 10,000/sec, and the peak value is as high as 2-3 million per second. In such cases, the ACS may not operate stably because it cannot be processed.

Name indicates the name of the policy; Class corresponds to the specific policy processing object; EventCode is the event number of the triggering policy; Parameter is the policy parameter. In the example, interval=630 indicates that the threshold of the periodic reporting interval is 630 seconds; Repair is repaired. The action, setParameterValues corresponds to the RPC method in TR-069, where oid and value indicate that the periodic reporting interval is set to 43200 seconds.

Second, the message preprocessor receives the Inform message reported by the CPE.

The TR-069Inform message example can be as follows:

In the above Inform message, OUI and SerialNumber are combined to form a device identifier, and the device identifier of each device is unique. The number before the space in the EventCode is the event number.

Step S702, extracting a CPE identifier, a TR-069 event number, and a time when the Inform message is received;

The message preprocessor extracts the CPE identifier and the TR-069 event number attribute from the TR-069 Inform received above, and records the two attributes and the time when the message preprocessor receives the Inform message. The message preprocessing module receives the 2-Periodic message, first converts the message into an HTTP message, and then converts it into a TR-069 Inform message object, extracts the device identifier and event number information from the TR-069 Inform message object, and combines the two information together The time received is recorded in memory.

Step S704, determining whether the CPE device is in a Rampage state;

The policy module determines whether the CPE is in the Rampage state according to the frequency of the 2-periodic received by the CPE device, and the judgment is based on the interval between the last two 2-Periodic messages being less than a preset threshold (for example, 630 seconds). Matching the event number extracted in step S702 with the event number EventCode of the trigger policy configured in step S700, finding a corresponding processing policy RampagePolicy, loading the policy processing class con.zte.ums.cpehg.neal.plocy.RampagePolicy, and starting the Policy and pass the TR-069 message object. According to the same device ID and the same event number, the TR-069 packet is sent from the same CPE device, and the time difference of the TR-069 packet received from the same CPE device is calculated. This time is compared with the periodic reporting interval threshold value configured in step S700. If the time difference from the TR-069 message sent by the same CPE device is less than or equal to the preset threshold, the CPE device can be considered to be in the Rampage state and further processing is required.

Step S706, transparently transmitting the message to the ACS;

When the condition that the CPE is in the Rampage state is not established, the message is directly transmitted to the ACS. According to step S704, if the calculated time difference is greater than the threshold, the 2-Periodic message is transparently transmitted to the ACS. For automatically processed messages, the message preprocessor responds normally with TR-069 to end the session and the process ends.

Step S708, determining whether the CPE device has undergone repair;

When the condition that the CPE is in the Rampage state is established, it continues to judge whether the CPE has never been repaired (this case refers to the reset period in step S710). According to step S704, if the calculated time difference is less than the threshold, the CPE device may report that the message period is too frequent and is in the Rampage state. Check the device maintenance record to determine whether the CPE device has been repaired or repaired, and perform the next step based on the result.

Step S710, reset the period of the CPE report message;

If the CPE has never been repaired, the reporting period of the reset CPE is 24 hours or other reasonable period interval; if the time difference is less than the threshold and the CPE has never been repaired, the repair action can be initiated, that is, sent to the device. The remote control command sends a message to the device to modify the period of the periodic report, which is used to reset the periodic reporting interval of the device. If the repair action fails, the device can generate an alarm message to notify the operator to manually troubleshoot the fault.

Step S712, generating alarm information.

If you have fixed a CPE, add the device to the manual intervention list. The CPE device has been repaired and is still in the Rampage state. It can be recognized that the device is not sporadic. It may have a serious fault or problem. Manual intervention is required. Alarm information can be generated or a work order can be generated to notify the device maintenance personnel or notify. The ACS upgrades the CPE.

For the example shown in FIG. 7, step S700 includes, but is not limited to, loading a configuration file, and may also load a database or a memory configuration. The configuration file is not limited to the XML format in the example, and may also adopt a format such as a Properties format, a data table, or other configuration format; in step S702, the 2-Periodic message is first converted into an HTTP message, and then converted into a TR-069 Inform message object. The necessary operations, as long as the device unique identifier and the event number can be extracted from the TR-069 message, and the information is not limited to be recorded in the memory, and can also be recorded in the configuration file or the database; in step S712 The alarm information is generated to notify the maintenance personnel to perform manual intervention, including but not limited to generating an alarm, which may be any form of notification and notification to the operator, for example, recording information to a text, a database, and notifying by email or SMS.

By adopting the method shown in FIG. 7, the network congestion caused by the message storm in the ACS and the CPE network and the network bandwidth being invalidated are effectively solved, the smooth operation of the ACS system is ensured, and the management stability and effectiveness of the CPE network are improved. Sex.

Example 2: A preferred embodiment of the present invention may also be directed to the CPE reporting a large number of invalid messages, which may be described in conjunction with FIG. Generally, there are two kinds of invalid messages appearing in the CPE network. One is an unrecognizable message, such as a continuous empty packet, the device is customized, and the Inform message is not in the carrier's specification. The other is clear. Know the Inform messages that you don't need to process.

FIG. 8 provides a method for processing a TR-069 message message for processing a problem that a CPE device reports a large number of invalid messages. FIG. 8 is a flowchart of a method for processing a TR-069 message according to a preferred embodiment of the present invention; as shown in FIG. 8, the method may include the following process:

Step S800, the system loads and configures a blacklist feature library.

The blacklist signature database is a set of invalid message instances defined in advance, and is used to determine whether the reported TR-069 packet is an invalid packet. The sample signature database configuration file format is as follows:

EventCodeEnabled=0,1,2,4,5,6,7,8, the event number in the whitelist configured as above.

Step S802: Acquire a TR-069 message reported by the CPE device; the message pre-processor receives the TR-069 Inform message reported by the CPE.

Step S804, extracting the event number of the message; the message preprocessor converts the Inform message received in step 202 into a TR-069 message object, and extracts the event number therein.

The message pre-processing module receives the TR-069 message, first converts the message into an HTTP message, and then converts it into a TR-069 Inform message object. If an exception occurs during the message conversion process, the message is considered invalid, and the empty message of the TR-069 is directly returned to the device to end the session.

Step S806, determining, according to the blacklist feature database, whether the message is an invalid message;

The policy module determines whether the Inform message received in step S802 is an invalid message according to the configured blacklist feature database. After the message is correctly converted into a TR-069 Inform message object, the event number is extracted, and the event number is in the feature library in step S800. The event number matches, and it is determined according to the matching result whether the message is an invalid message.

In step S808, the message is directly transmitted to the ACS; if the match is unsuccessful, the message is considered to be invalid, and the message can be directly transmitted to the ACS. Step S810, the current session is removed; if the matching is successful, the message is considered to be an invalid message, and the session is normally ended according to the TR-069 protocol specification; if the Inform message is an invalid Inform message, the message preprocessor responds to the CPE device with an Inform Response. Message used to dismantle this session.

In step S812, the session is ended. The message preprocessor receives the Empty Request message reported by the CPE, and the message preprocessor replies to the CPE with an Empty Response message.

It should be noted that the steps of the method apply some standard interaction processes belonging to the TR-069 protocol specification. The conversion to the TR-069 message object in step S804 is not an essential operation, and other methods that can extract the device unique identifier and the event number from the message may be used.

Further, step S800 is not limited to loading a configuration file, and may also load a database or a memory configuration. The configuration file is not limited to the Properties format in the example, and may also be in an XML format, a data table, or other configuration format. The configured blacklist packet feature database can also be a TR-069 valid event list, such as a whitelist message signature database. Correspondingly, step S806 is adaptively changed to: the policy module determines, according to the configured whitelist feature database, whether the Inform message received in step S802 is an invalid message. Matching the event number with the event number of the whitelisted library. If the matching is successful, the message received in step S802 is valid, and the message can be directly transmitted to the ACS; if the matching fails, the received message can be considered invalid. The message can be terminated normally according to the TR-069 protocol specification.

The method provided in the second method is used to determine the validity of the packet, and the invalid packet is directly discarded. The invalid message can be intercepted outside the ACS to avoid consuming the ACS resources and suppress the invalid traffic in the network. The generation, thereby reducing bandwidth resource consumption, improving bandwidth utilization, and improving system stability.

In summary, the embodiments, the preferred embodiments, and the examples of the present invention provide a method and a device for efficiently processing TR-069 invalid or abnormal message messages, and setting a policy for pre-processing message messages to determine the CPE device reporting. Whether the packet message is abnormal or invalid, further determining whether the CPE device can be repaired, processing the TR-069 message and maintaining the CPE device according to the policy, can effectively determine the abnormal state device in the network, and restore the device to normal. Therefore, the total transmission of invalid messages in the network is reduced, and the invalid network bandwidth is reduced. The resources of the ACS can be effectively used for the management of the service, ensuring the smooth operation of the ACS system, and improving the management stability and effectiveness of the CPE network. .
