Solution Overview

Problem

Current VoIP network construction requires significant computing resources and high costs due to the need for dedicated hardware like DSP chips and multiple CPU cores for media encoding/decoding, leading to inefficient resource allocation and high construction costs, while also being sensitive to delay and packet loss.

Innovation Solution

A voice over Internet protocol processing method that offloads computing functions from access network elements to a cloud server, optimizing network resource configuration and simplifying processing capabilities, thereby reducing construction costs and improving network efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated DSP chips or independent CPU cores are allocated for voice media encoding/decoding in access network elements, then voice service quality is ensured, but construction costs increase significantly

Engineering Contradiction:
Improvevoice service qualityVSAvoidconstruction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the media encoding/decoding function from the access network element and relocates it to a cloud server. The access network element retains only signaling processing capabilities, while the computationally intensive media processing is performed remotely by the cloud server, thereby reducing hardware requirements and construction costs at the access network level while maintaining voice service quality.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If computing resources are reserved in access network elements for voice services, then service reliability is improved, but network efficiency decreases due to low resource utilization

Engineering Contradiction:
Improveservice reliabilityVSAvoidnetwork efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent makes computing resources universal by consolidating media encoding/decoding capabilities in a cloud server that can serve multiple access network elements and multiple voice services simultaneously. This multi-functional resource pool allows dynamic allocation and sharing of computing resources across different services and users, improving overall network efficiency while maintaining service reliability through centralized resource management.

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