Method and device for diagnosing faults of 5G CPE (customer premises equipment)

Technical Field

The invention relates to the field of network fault diagnosis, in particular to a method and a device for diagnosing faults of a 5G CPE.

Background

With the maturity and development of the 5G communication technology, the 5G technology is deployed to enterprises in a large scale, and the digital transformation process of various industries is promoted. At present, 5G in the fields of intelligent transportation, logistics, security, medical treatment, electric power, buildings, intelligent houses, agriculture, intelligent manufacturing, mining industry and the like goes deep into all production links, and strict requirements of enterprise customers on mobile communication are supported through the characteristics of low time delay, high bandwidth and large capacity of a 5G key technology.

The current 5G technology belongs to a large-scale deployment stage in the industry, enterprises sink through UPF to construct own 5G networks to achieve the purpose of low time delay, and the previous communication technologies such as 4G and wired are changed into 5G communication to support enterprise production. At present, 5G CPE is generally used for access, the lower end of the CPE is connected with production equipment, the production equipment sends data to the 5G CPE, the data is transmitted to a base station in an uplink mode and then to an enterprise for measurement through a UPF or a regional shared UPF stream in the enterprise, and real-time sensing and control of the enterprise on the production data are achieved.

UPF: the method is an important component of a 3GPP 5G core network system architecture and is mainly responsible for routing and forwarding related functions of user plane data packets in a 5G core network.

Because 5G promotes the communication scheme before replacing when main, for faster, more convenient use 5G, the enterprise side generally reforms transform the preceding circuit through built-in 5G CPE, and current 5G CPE's manufacturing enterprise is more, and each production line, region require different CPE to use the CPE of multiple manufacturers simultaneously when probably purchasing. However, various CPEs do not have a uniform platform for hosting, so that the CPEs are likely to be off-line and cannot be remotely operated once problems occur, and enterprise customers and operators cannot go on to do work when problems need to be handled.

s100, multi-protocol adaptation, wherein the protocol adaptation supports multiple modes, including tr069, mqtt, rest, ssh, telnet, snmp and syslog. The protocol adaptation supports two modes of active reporting and passive acquisition, and because the types of the CPE are various and the protocols supported by manufacturers are different, the platform side cannot adapt to all the CPE through one protocol.

S101, collecting CPE information. The CPE information comprises configuration information, performance information and module information, wherein the configuration information comprises CPE model information, CPU (central processing unit), memory, disk and system version information, the performance information comprises CPU utilization rate, memory utilization rate, uplink and downlink rate, disk utilization rate, IO (input/output) service condition, network delay, packet loss and jitter, and the module information comprises online state, online duration, RSRP (reference signal received quality), RSRQ (reference signal received quality), SINR (signal to interference plus noise ratio), cell information and the like.

An active reporting mode, wherein protocols mainly supported by the active reporting mode are tr069, mqtt and syslog modes, and a terminal dynamic IP (Internet protocol) can be supported, wherein the tr069 mode needs to judge whether effective data exist or not according to a data node after data is reported by a CPE (customer premises equipment), and key attributes are actively acquired through the data node, and the key attributes mainly comprise a 5G module operation index, a configuration index, terminal information, alarm information and the like.

Judging the valid data: one or more items containing configuration, performance and module information of the CPE device are considered valid data.

The data node is for example:

InternetGatewayDevice.DeviceInfo.SoftwareVersion

and a passive acquisition mode which mainly supports rest, ssh, telnet and snmp protocols and can actively establish connection with the terminal CPE to initiate acquisition. The passive acquisition mode can flexibly define an acquisition period and acquisition indexes, and meanwhile, different positions can be detected through ping, and the different positions represent IP address information of different equipment or server platforms to acquire time delay information. Besides the indexes, the passive acquisition mode can also support the push of an rtp video stream, the establishment of a TCP connection for speed test and the like, and for testing CPE, the high-pass 5G module signaling information can be acquired through a built-in program, the high-pass 5G module signaling acquisition program is communicated with the modules through a serial port to acquire signaling data.

S102, collecting core network side information, wherein the core network side information mainly comprises account opening information, machine-card binding information and area limiting information of a terminal.

When the CPE has a problem, the judgment needs to be carried out from the CPE side, the core network and the wireless access, if the core network side has the problems of shutdown arrears, area limitation and machine-card binding, the problem can be realized by the inquiry interface of the core network side, and the subscription information of the terminal card is inquired.

The core network side information mainly judges whether a user is shut down or not and is bound by a machine card, and if the shut down or the binding of the machine card is abnormal, the core network side has problems.

The core network state comprises signed DNN, state, machine-card binding, area limitation, package information and the like.

The method supports setting the state or threshold of the abnormal index according to the index category, and can hit syslog alarm, abnormal AT instruction and operation according to the regular configuration abnormal matching. The regular matching is built-in abnormal index information, and if a specific restart instruction, failure or error description is contained, the abnormal index information represents an abnormality.

S104, judging whether the CPE is abnormal or not, wherein the judgment is carried out according to the acquired indexes, and if the indexes are not within the threshold value, the indexes are considered to be abnormal, or if the indexes are not in the threshold value, the indexes are considered to be abnormal;

The multi-process refers to performance index judgment acquired by the CPE, index judgment of dial testing program testing and index judgment acquired by a signaling acquisition program.

The judgment condition refers to that the index threshold value can be modified and increased, the criterion can be regular, and whether the signaling flow is judged.

The main anomalies include: the method comprises the following steps of abnormal disconnection of a terminal, abnormal restart of the terminal, overlarge time delay of the terminal and blockage of a video of the terminal.

Taking abnormal disconnection of the terminal as an example for analysis:

the triggering condition is that ping packet loss is 100%, the main process judges whether the core network state is defaulted, the branch process judges the wireless signal state, whether the base station side gives an alarm or not, and if no fault exists, whether the terminal is powered down or not is judged, so that the terminal is not on-line, and the ping packet loss is 100%:

others are, for example: and the terminal video card is used for testing whether the uplink and the downlink are stable through the flow velocity, judging whether the access base station has excessive equipment and flow, judging whether the RTP is out of order and the like. The method can modify the flow judgment and the threshold value according to the actual situation, and can check whether the 5G module is recovered or not by restarting the 5G module through the interface.

And judging whether a group fault phenomenon exists in the same enterprise, the same base station and the same area according to the positioned fault reason, and assisting in judging the fault reason.
