Cell Outage Detection for Network Sharing Operators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network sharing scenarios, existing cell outage detection methods often incorrectly determine whether a cell is operational or not, leading to unnecessary compensation and disruption of service for non-outage operators, preventing users from accessing the cell.
Innovation Solution
A method and apparatus that monitor working status information of multiple operators in a cell to accurately determine outage cells and operators, performing compensation only for the affected operator, allowing non-outage users to access the cell while preventing unnecessary resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cell outage detection method is used to determine cell operational status, then outage detection is performed, but non-outage users are incorrectly prevented from accessing the cell
Solution Approach 1:
The patent segments the cell into multiple operator-specific service areas. Instead of treating the cell as a single unified entity, it divides the cell into operator-specific segments (e.g., Operator 1 area, Operator 2 area) within the same cell. This allows independent outage detection and compensation for each operator, so that when one operator experiences an outage, only users of that specific operator are prevented from accessing their segmented area, while users of other operators can still access their respective areas without interruption.
2Reliability
If compensation is performed for the entire cell when one operator encounters outage, then the outage operator is protected, but resources are wasted and non-outage operators are affected
Solution Approach 1:
The patent applies local quality by making the compensation mechanism operator-specific rather than cell-wide. When an outage is detected for a particular operator, the compensation action (preventing access) is applied locally only to that operator's users in their segmented area, not to all users in the entire cell. This ensures that compensation is effective for the affected operator while avoiding unnecessary resource consumption and service disruption for non-affected operators who continue to have full access to their areas.
3Productivity
If network sharing is implemented to reduce construction costs, then cost efficiency is improved, but outage detection complexity increases
Solution Approach 1:
The patent introduces operator identification mechanisms and service area segmentation that work within the existing network sharing infrastructure. By segmenting the cell into operator-specific areas and implementing targeted compensation, the system manages the complexity of multi-operator environments without requiring complete system redesign, thus maintaining cost efficiency while handling outage detection.
Solution Approach 2:
The patent employs an intermediary mechanism (operator identification and service area mapping) that sits between the physical cell infrastructure and the logical operator services. This intermediary layer enables the system to track and manage multiple operators sharing the same cell, providing the necessary information for accurate outage detection and targeted compensation without directly complicating the underlying network infrastructure.
