Solution Overview

Problem

Existing communications networks lack the ability to effectively share and utilize Network Aware data between the radio network and service network, leading to suboptimal service delivery and resource usage due to the absence of explicit information exchange and control signaling.

Innovation Solution

A gateway node in the mobile core network is introduced to identify and route Network Aware data to specialized nodes, performing deep packet inspection and address mapping to ensure appropriate handling, and implementing Smart Mobile Broadband Protocol Framework (SMPF) for efficient data exchange between the radio and service networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If centralized service network functionality is used without explicit information exchange, then device complexity is reduced, but information availability between radio network and service network deteriorates

Engineering Contradiction:
Improvenetwork structure complexityVSAvoidNetwork Aware data availability
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

A gateway node is introduced as an intermediary between the radio network and service network. This gateway node receives data from the radio network, identifies Network Aware data through inspection, and routes it to appropriate service network nodes. This intermediary approach enables information exchange without requiring complex direct connections between all network entities, thus resolving the contradiction between maintaining simple centralized structure and enabling information availability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If Network Aware data is routed to all nodes, then information availability is improved, but message handling complexity increases

Engineering Contradiction:
ImproveNetwork Aware data availabilityVSAvoidmessage routing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The gateway node extracts and identifies Network Aware data from the data stream using inspection mechanisms. Instead of routing all data to all nodes, the gateway node selectively extracts only the relevant Network Aware data and routes it to specific service network nodes that require it. This extraction approach reduces unnecessary message handling complexity while ensuring that needed information reaches the appropriate nodes.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If deep packet inspection is performed to identify Network Aware data, then data identification accuracy is improved, but processing time increases

Engineering Contradiction:
Improvedata identification accuracyVSAvoidmessage processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The gateway node performs deep packet inspection selectively rather than on all data packets. It applies inspection primarily to identify Network Aware data, which is a subset of the total data traffic. This partial action approach maintains high identification accuracy for the critical Network Aware data while avoiding the time penalty of inspecting every single packet in the network, thus balancing accuracy with processing time.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A method and apparatus for handling data between a radio network and a service network, the data comprising Network Aware data. A gateway node in a mobile core network receives a message from the radio network. It then determines whether the message comprises Network Aware data. If it does, then the message is routed to a Packet Data Network Gateway node configured to handle Network Aware data. If it doesn't, then the message is routed to a Packet Data Network Gateway node for message handling. This ensures that non-Network Aware data is handled using regular message handling, and Network Aware data is handled by nodes configured to handle Network Aware data.
