What is Mobile Telecom Network Fault Management and Why is Fault Analysis Important?

Definition

Network fault management is the process of detecting, isolating, and correcting network malfunctions and inconsistencies in a telecommunications network. The fault management function compensates for system, usage and environmental changes, and covers error and alarm maintenance, analysis, categorization, automation, and resolution.

Why is Fault Analysis Important?
A mobile telecom fault management system receives error detection notifications, tracing and identifying faults. Fault analysis carries out sequences of diagnostics root cause tests on this data, providing insights on possible corrective measures, reporting error conditions, and localizing and tracing faults by examining and manipulating database information generated from network-wide fault collection parameters.

Types Of Mobile Telecom Network Data And Alarms That Are Monitored With Network Fault Management

Mobile telecom fault management systems analyze and report five core network failure events and alarms:

  • Resource Failure Alarms (e.g., power outage, natural disaster)
  • Equipment Failure Alarms (e.g., mast misalignment, wire cuts)
  • Database Failure Alarms (e.g., issues with cloud and virtualized
    environments)
  • Software Failure Alarms (e.g., software updates, bugs)
  • Configuration Error Alarms (e.g., configuration inconsistencies)

Using Artificial Intelligence (AI) to Detect and Correct Faults in Mobile Telecom Networks

Multi-Vendor, Multi-Technology Network Environments

Multi-vendor and multi-technology network environments significantly increase the chances of errors and inconsistencies, resulting in more alarms. AI can address these alarms quickly and efficiently and act upon or escalate the critical ones while automatically resolving repetitive alarms.

Rapidly Growing Networks
Rapidly growing networks due to IoT and machine-to-machine devices create dense networks prone to errors and inconsistencies. AI accurately and efficiently addresses a torrent of alarms at scale across heterogeneous networks while reducing MttR and guaranteeing network quality.
Increased Competition for Users

Quality of Experience (QoE) is an increasingly prominent KPI as MNOs battle it out with competitors for subscribers. Investing in AI technologies accelerates the isolation, identification, classification, and resolution of alarms, unlocking efficiency gains that empower MNOs to remain competitive.

Overcoming Network Expansion Constraints

Networks are snowballing, overstretching NOCs as the complexity of managing them increases. Onboarding new devices, nodes, and network functions using AI-powered integrated network fault management systems results in fewer errors and inconsistencies, significantly shortening MttR and supporting network quality.

Innovile INNSPECT Mobile Telecom Network Fault Management Solution Architecture and Modules

Closed Loop Alarm Management Process

Innovile Collectors gather alarms from different sources, mainly NMS systems. External data sources can be also integrated into the system via stream, file, or API methods.

Once an alarm is collected, it is written to the INNSPECT database. Also, if an external system needs to be triggered with specific input, it can be started here.

Depending on the type of alarm and alarm source, an additional post-process can be required. INNSPECT network fault monitoring solution supports:

  1. Active Control: Checks if the same alarm is collected before and is still active.
  2. Duplicate Control: Checks if the same alarm was issued as an active alarm before, whether required notifications send or not, can be grouped with other alarms, etc.
  3. Threshold Control: Checks if the alarm trigger threshold (customizable) is passed or not; if passed an active alarm is raised.
  4. Count Control: Checks if the alarm is triggered multiple times (customizable) in a certain period (customizable), and if passed, an active alarm is raised.
  5. Clearance Control: Checks if the active alarms are still informed by source systems. If clearance is triggered, active alarms are closed automatically.

Most software-related alarms can be solved in a similar way or using a pattern algorithm. INNSPECT is powered by AI-based algorithms to detect patterns at an alarm-source-network level and starts correction modules if configured. With this approach, most alarms are solved automatically before causing major problems in the network.

All changes start with the Alarm Correlation and trigger a notification action. So, when a new alarm is created, updated, cleared, automatically corrected, or cannot be corrected, a notification is triggered.
