Solution Overview

Problem

Existing communication network access networks face inefficiencies and increased costs due to the inability to handle increased traffic and complex content delivery, particularly with multimedia, without the need for expensive upgrades or changes to existing devices.

Innovation Solution

A bypass device is introduced in the access network to bypass intermediate service platforms, processing specific data types while allowing other data to be handled by existing infrastructure, thereby optimizing data traffic and adding functionality without upgrading devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing intermediate service platforms are used to handle increased traffic, then network coverage and user connectivity are maintained, but network throughput and content delivery speed degrade

Engineering Contradiction:
Improvecontent delivery speedVSAvoidnetwork service stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments network traffic into two categories: packet-switched data traffic (which bypasses the intermediate service platform through a dedicated bypass device) and circuit-switched control traffic (which continues to flow through the intermediate service platform). This segmentation allows high-volume data traffic to be handled separately from control signaling, improving throughput while maintaining service stability through the traditional control path.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a bypass device as an intermediary component that sits between the gateway and the intermediate service platform. This bypass device selectively intercepts and handles packet-switched data traffic, allowing it to bypass the intermediate service platform while still maintaining connectivity through the core network. The bypass device acts as a mediator that preserves the existing control plane while creating an optimized data plane.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If devices in the access network are upgraded to handle greater traffic amounts, then network throughput and efficiency improve, but deployment cost and complexity increase

Engineering Contradiction:
Improvenetwork throughputVSAvoidaccess network device complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the packet-switched data handling function from the intermediate service platform and places it in a dedicated bypass device. This extraction allows the intermediate service platform to maintain its existing complexity level while the bypass device handles the additional data traffic burden. The function is separated rather than integrated, avoiding the need to upgrade the core intermediate service platform.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The bypass device is designed to work with existing intermediate service platforms without requiring modifications to them. The intermediate service platform maintains its universal compatibility with various core network configurations while the bypass device adds multi-functionality by handling both packet-switched data traffic and allowing circuit-switched traffic to pass through. This multi-functionality is achieved without upgrading the original platform.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If all data traffic is processed by intermediate service platforms, then service consistency is maintained, but network bandwidth utilization and delivery efficiency decrease

Engineering Contradiction:
Improvebandwidth utilizationVSAvoidservice handling consistency
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies local quality by treating different types of traffic differently based on their specific requirements. Packet-switched data traffic receives optimized handling through the bypass device with dedicated processing paths, while circuit-switched control traffic continues to receive consistent handling through the intermediate service platform. Each traffic type is routed through the most appropriate processing path for its characteristics.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The bypass device dynamically routes traffic based on the type of data being transmitted. It selectively bypasses packet-switched data traffic while allowing circuit-switched traffic to flow through the intermediate service platform. This dynamic routing decision is made in real-time based on traffic classification, optimizing bandwidth utilization while maintaining service consistency for control functions.

Inventive Principle:
Principle #15Dynamics

AI summary

A method in an electronic device (230) and a system for use in a communication network including a core network (110) and at least one access network (200) are described. Intermediate service platforms in an access network process data bound from a base station (260) towards a core network, and vice versa. A first data channel (212) or stream is processed by the intermediate service platform (220). Exemplary embodiments bypass the intermediate service platform by intercepting a second data channel (214) or stream bound for the intermediate service platform. The data in the second data channel or stream is processed and inserted into a data channel or stream downstream of the intermediate service platform.
