Multi-Level Change Request Risk Assessment for Telecom Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing change management systems in telecommunications networks use a uniform risk assessment approach for all change requests, regardless of network level, lacking the ability to tailor risk assessments to specific types or levels of changes.
Innovation Solution
The system allows users to specify parameters and algorithms for risk assessment, enabling tailored risk evaluations for different types and levels of change requests by using customizable risk assessment questionnaires and forms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a uniform risk assessment approach is applied to all change requests, then the system is simple to operate, but it cannot provide tailored risk assessments for different network levels
Solution Approach 1:
The patent segments the change request assessment process into multiple hierarchical levels (network level, domain level, network element level). Each level has its own specific parameters and risk assessment criteria, allowing tailored evaluation for different types of changes while maintaining overall system structure.
Solution Approach 2:
The system dynamically adapts the risk assessment approach based on the determined level of the change request. The assessment parameters, algorithms, and criteria automatically adjust according to the network level identified, providing versatility without requiring manual reconfiguration.
2Measurement precision
If multiple risk assessment algorithms are provided for different network levels, then tailored risk assessments can be provided, but the system becomes more complex
Solution Approach 1:
Each network level (network level, domain level, network element level) has its own specialized risk assessment parameters and criteria tailored to that level's specific characteristics. For example, network level assessments consider overall network impact while network element level assessments focus on component-specific risks.
Solution Approach 2:
The system changes the assessment parameters based on the determined change request level. Different levels trigger different parameter sets and calculation algorithms, allowing precise risk measurement for each level while managing complexity through automated parameter selection.
3Productivity
If a single risk assessment form is used for all change requests, then the system is easy to operate, but it cannot efficiently process different types of change requests
Solution Approach 1:
The system performs preliminary determination of the change request level and type before initiating the risk assessment. This preliminary classification automatically selects the appropriate assessment form and parameters, streamlining the process for different change types without requiring users to manually choose assessment criteria.
Solution Approach 2:
The system uses a universal multi-level assessment framework that can handle different types of change requests (new installations, modifications, maintenance) across all network levels through a single integrated process, maintaining ease of operation while improving processing efficiency.

AI summary
A method for assessing risk for a change request in a mobile communications system and network includes receiving a first user input from a user for creating the change request, determining a level of the change request, from among a plurality of predetermined levels associated with the mobile communications system, determining a risk assessment form corresponding to the determined level of the change request, from among a plurality of predetermined risk assessment forms respectively corresponding to the plurality of predetermined levels, wherein each of the plurality of predetermined risk assessment forms calculates a risk differently based on the plurality of predetermined levels, outputting the determined risk assessment form to the user, receiving, from the user, a second user input regarding the change request to the risk assessment form, and determining a risk level of the change request based on the second user input.
