Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable media for node failure identification and recovery. In the embodiments, a first network device for a radio access network detects an error of communication over a first interface between the first network device and a third network device. The first network device transmits to a second network device of the radio access network, a request for the second network device to check status of a second interface between the second network device and the third network device. Then the first network device receives, from the second network device, status information on the second interface.

Abstract: Embodiments of this application provide a communication method and a communication apparatus. The communication method includes: A first network element sends at least one piece of check content to a second network element, where the check content indicates an abnormal event that causes a fault of a second network; and the first network element receives at least one check result from the second network element, where the check result indicates whether the abnormal event occurs in the second network. In this way, the first network element can obtain the check result detected by the second network element based on the check content, to determine a fault root cause. This implements cross-operator fault diagnosis, and improves a fault diagnosis capability and an intent achievement rate.

Abstract: A method includes: receiving protocol event data from a plurality of probes within the telecommunication system; determining a most probable cause of a call event from the protocol event data; applying the most probable cause to a trained machine learning algorithm that includes the most probable cause as its input and a telecommunication system score as its output; and in response to an output score from the trained machine learning algorithm, performing a corrective action for a plurality of network users that are expected to be affected by the most probable cause.

Abstract: A method, implemented at a computer system in a network, for localizing network failure in the network includes enumerating at least one path between the computer system and a path destination node in the network through one or more intermediary nodes. The method further includes enumerating a plurality of sub-paths between the computer system and the path destination node. Each sub-path has either the path destination node, or one or more intermediary nodes of the corresponding path as a corresponding sub-path destination node. For each of the plurality of sub-paths, determining a probability that a data packet can successfully traverse the round trip of the corresponding sub-path and identifying a node in the network where network failure have occurred.

Abstract: Systems, methods, and devices that relate to efficient incident management using multi-dimensional correlation across different layers of the network are disclosed. In one example aspect, a method for wireless communication includes receiving reporting information about a network incident associated with multiple network nodes in a network, and identifying a network node or a connection between two network nodes as a root cause for the network incident based on a multi-dimensional correlation that correlates one or more sets of horizontal information in respective layers of an Open Systems Interconnection (OSI) model and vertical information across multiple layers of the OSI model.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for data processing to monitor and trigger alerts based on identified technical issues at instances running in a cloud platform environment. Availability data for the cloud platform can be collected. Based on evaluation of the availability data, a determination that at least a portion of a set of services are experiencing issues can be made. A detailed check is triggered to collect data logs, metrics, and dependencies data for at least the portion of the set of services. An overall status of performance of the cloud platform based on obtained service status data from the detailed check can be determined. Based on analysis of the overall status of performance of the cloud platform, execution of causal engine logic to identify an issue at the cloud platform can be performed, and a notification for the issue can be provided.

Abstract: A method includes processing event data to detect a status of a network function. The event data is processed based on two or more conditions defined by a correlation policy. The correlation policy includes a non-deterministic finite automata tree (NFAT) structure correlation policy having a policy type. The method also includes determining a first value of a first condition of the two or more conditions. The method further includes determining a second value of a second condition of the two or more conditions. The method additionally includes determining the policy type of the NFAT structure correlation policy. The method also includes determining whether the first value is greater than a first preset value indicative of whether the first condition is satisfied. The method further includes determining whether the second value is greater than a second preset value indicative of whether the second condition is satisfied.
