Mobile Network Presence Map for Signaling Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network systems face inefficiencies in managing quality of service and tariff rules due to unnecessary signaling traffic generated by location changes of mobile terminals, as most location areas share the same characteristics, leading to redundant signaling and increased network load.
Innovation Solution
A method that filters and groups relevant location information into a presence card, which is transmitted only when necessary, using zonal information to identify special zones with unique processing rules, reducing unnecessary signaling and optimizing network traffic by associating terminal identifiers with location zone identifiers and applying session processing rules accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location change notification is activated for all mobile network users, then real-time quality of service modification is enabled, but heavy signaling traffic is generated
Solution Approach 1:
The patent extracts and processes only the relevant portion of location information by filtering location changes based on pre-configured quality of service policy areas. Instead of processing all location changes, the system identifies and processes only those location changes that occur within specific geographic areas where quality of service modifications should be applied, thereby reducing signaling traffic while maintaining real-time quality of service modification capability.
Solution Approach 2:
The patent performs preliminary configuration of quality of service policy areas before location change notifications are processed. By pre-defining which geographic areas should trigger quality of service modifications, the system prepares filtering criteria in advance, enabling efficient real-time processing of location information without generating unnecessary signaling traffic for areas where no policy changes are needed.
2Reliability
If location change notification is activated for all mobile network users, then location-based quality of service modification is enabled, but network resizing is required to handle the load
Solution Approach 1:
The patent extracts only the necessary location information related to pre-configured quality of service policy areas, rather than processing all location data. This selective extraction approach enables location-based quality of service modification without requiring network architecture expansion to handle unnecessary data processing loads.
Solution Approach 2:
By pre-configuring quality of service policy areas and criteria before runtime, the patent prepares the system in advance to efficiently process location information. This preliminary setup enables the network to handle location-based quality of service modifications using existing infrastructure without requiring architectural resizing or additional complexity.
3Loss of information
If all location changes are processed, then complete location tracking is achieved, but most signaling is useless as many areas share the same quality of service characteristics
Solution Approach 1:
The patent extracts and processes only the relevant subset of location information by filtering based on pre-configured quality of service policy areas. Instead of processing all location changes, the system identifies and processes only those location changes that occur within areas where quality of service modifications should be applied, eliminating useless signaling while maintaining complete tracking capability for areas that matter.
Solution Approach 2:
The patent applies different processing quality to different geographic areas by configuring specific quality of service policy areas. Location changes within these configured areas receive detailed processing and potential quality of service modifications, while location changes outside these areas are filtered out. This local quality approach ensures complete tracking where needed while eliminating redundant signaling in areas with identical quality of service characteristics.
