specific Embodiment approach

[0032] A concept of User Service Performance (USP) has been proposed that provides service quality measurements and a service and technology class approach that defines the measurement structure to support root cause analysis. See eg WO2008 / 121062. In the USP concept, consider system services and resource services. System services, including web browsing, streaming, and television, are defined as technology-independent and defined as end-user experience possible. This end user can be a human or a machine consuming the service through a terminal such as a mobile phone, screen or video camera. Resource services, on the other hand, are logical or physical entities composed to deliver system services and are based on resources such as bearers, links and nodes.

[0033] The performance of both system services and resource services is characterized by key performance indicators. Service key performance indicators (S-KPIs) and resource key performance indicators (R-KPIs) provide a...

Abstract

A method (100) for root cause analysis of quality of service degradation in a communication network is provided. The method includes receiving (102) measurements from a plurality of nodes in a communication network, determining (104) identifiers of the received measurements, determining (106) a network topology using the identifiers of the received measurements; and based on the determined topology and performing (108) a root cause analysis with measurements linked with the topology.

Description

technical field [0001] The present invention relates to methods and devices for root cause analysis, in particular, to methods and devices for root cause analysis of quality of service degradation in communication networks. Background technique [0002] One of the main responsibilities of service providers is to ensure that their service offerings meet the promised levels of performance and robustness as stated in their service level agreements (SLAs) with consumers. The standard approach is to monitor the quality and behavior of services by measuring system internal performance characteristics (for example, round-trip delay, available bandwidth, and loss ratio), identifying irregular or unusual activity that either directly indicates or indirectly implies that the service is no longer behaving satisfactorily . These measurements allow detection of quality degradation or loss of function. In addition, service root cause analysis (S-rca) can be used to analyze the (root) ca...
