Mobility Management Entity Presence Reporting Priority Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing presence reporting mechanism in communication networks, which allows multiple presence reporting areas per subscriber, leads to increased network traffic and resource consumption, potentially causing network overload due to frequent updates of terminal locations across multiple areas.
Innovation Solution
A method that assigns priority levels to each presence reporting area and suspends the presence reporting mechanism for areas with lower priority when network load exceeds a critical threshold, reducing unnecessary reporting and alleviating the load on mobility management entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple presence reporting areas are associated per subscriber profile, then the ability to track terminal location across different geographic areas is improved, but network traffic and resource consumption increase
Solution Approach 1:
The presence reporting areas are segmented into multiple priority levels (first priority, second priority, etc.). The system can selectively suspend reporting for lower priority areas while maintaining reporting for higher priority areas, thus reducing overall network traffic while preserving essential location tracking capabilities.
Solution Approach 2:
The system dynamically changes the operational state of presence reporting by introducing priority levels and suspension mechanisms. When network load exceeds a threshold, the system changes the parameter of reporting activity from active to suspended for lower priority areas, thereby adapting network traffic to current load conditions.
2Measurement precision
If multiple presence reporting areas are monitored, then location awareness is improved, but mobility management entity load increases
Solution Approach 1:
The monitoring function is segmented by priority levels. The mobility management entity monitors multiple presence reporting areas but processes them differently based on priority. When load is high, monitoring for lower priority areas is suspended, reducing processing load while maintaining monitoring for critical high priority areas.
Solution Approach 2:
The system introduces dynamic load-based control where the mobility management entity adjusts its monitoring activity based on current load conditions. The entity can dynamically suspend or resume presence reporting for different priority areas, making the monitoring process adaptive to real-time system state rather than static.
3Adaptability or versatility
If presence reporting is activated for multiple areas, then service coverage is improved, but network overload risk increases
Solution Approach 1:
The system takes preliminary anti-action by implementing a suspension mechanism that activates before network overload occurs. When load exceeds a predefined threshold, the system proactively suspends presence reporting for lower priority areas to prevent overload, rather than waiting for failure conditions.
Solution Approach 2:
The system dynamically adjusts service coverage by suspending presence reporting for lower priority areas when network load is high, and resuming when load decreases. This dynamic adjustment maintains service coverage for critical areas while preventing network overload through selective reduction of non-critical reporting.

AI summary
A method for managing, in a communication network, network traffic related to a mechanism for signaling the presence of a terminal in a plurality of presence-signaling areas. A mobility management entity receives, for each presence-signaling area of the plurality, an area identifier and a priority level for the area then stores, in a piece of subscriber context related to a subscriber of the terminal, the identifiers and priority levels received in association with an identifier of the terminal. When the load of the mobility management entity is higher than a predefined critical load threshold, the entity suspends the presence-signaling mechanism for the presence-signaling areas, referred to as non-monitored areas, of the plurality in which the priority level is lower than a transitional priority level.
