Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing optimizing solutions for 3G wireless networks do not account for the Radio Access Network (RAN) condition, leading to inefficient data and video traffic management, and there is a need to reduce the load on core network elements like the SGSN while extracting more network information.

Innovation Solution

An intermediate entity is inserted between the RAN and the core network to parse control plane messages, determine the RAN's current state, and manage bandwidth dynamically by intercepting and processing UE location messages, preventing unnecessary location information from reaching the core network, and emulating the core network element to the RAN.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If UE location messages are processed by the core network element (SGSN), then location information is accurately tracked, but the load on core network elements increases

Engineering Contradiction:

Improvelocation information accuracyVSAvoidcore network element load

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

An intermediate entity is introduced between the RAN and the core network element to intercept UE location messages. This intermediary extracts location information from the messages and prevents the full messages from reaching the core network, thereby reducing core network load while maintaining location tracking capability through the intermediate entity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If existing optimizing solutions are implemented without considering RAN condition, then some traffic management is achieved, but data and video traffic management efficiency is insufficient

Engineering Contradiction:

Improvetraffic management capabilityVSAvoidRAN condition awareness

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The intermediate entity monitors and determines the current state of the RAN by analyzing control plane messages. This feedback mechanism provides real-time information about RAN conditions (such as congestion status) back to the optimization system, enabling dynamic adjustment of traffic management strategies based on actual network state

Inventive Principle:

Principle #23Feedback

3Productivity

If an intermediate entity is inserted to intercept and process messages, then core network load is reduced, but network architecture complexity increases

Engineering Contradiction:

Improvecore network element load reductionVSAvoidnetwork architecture complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The intermediate entity is positioned between the RAN and core network to perform message interception and processing. It extracts necessary location information and prevents unnecessary messages from reaching the core network, reducing core network load while centralizing the complexity in a single intermediate component rather than distributing it throughout the network

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A non-transitory computer readable medium and a method for gathering user equipment (UE) location information from a radio access network (RAN), the method may include: intercepting a UE location message sent from the RAN towards a core network element configured to process UE location messages, wherein the intercepting is executed by an intermediate entity positioned between the RAN and the core network element; extracting UE location information from the UE location message; and preventing the core network element from receiving the location information embedded in the UE location message.
