Solution Overview
Problem
Current packet radio communications systems, such as GPRS, face challenges in efficiently managing the rapid growth of internet protocol data traffic and services, requiring enhanced flexibility and support for diverse internet protocol networking and transport technologies.
Innovation Solution
A packet radio communications system is designed with a core network and radio access networks connected via an internet protocol transport plane, utilizing a common gateway support node to establish communications bearers across packet data networks, incorporating standardized and non-standardized GPRS components, and supporting heterogeneous radio access networks to cater to increasing internet protocol traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPRS networks use traditional circuit switched architecture, then network stability is maintained, but flexibility and adaptability to rapid growth in internet protocol data traffic deteriorate
Solution Approach 1:
The network architecture is segmented into multiple packet data networks (PDNs) with different telecommunications standards, allowing each segment to operate independently with optimized protocols while being coordinated through a common gateway support node
Solution Approach 2:
A common gateway support node is introduced as an intermediary to manage communications bearers across heterogeneous PDNs, enabling unified control and policy enforcement without requiring complete architectural overhaul of existing networks
2Adaptability or versatility
If a single packet data network operates in accordance with one telecommunications standard, then network management is simplified, but the ability to support diverse internet protocol services and heterogeneous radio access networks deteriorates
Solution Approach 1:
The common gateway support node provides universal functionality by managing communications bearers across multiple PDNs with different standards, enabling a single node to handle diverse internet protocol services including IMS services while maintaining unified control
3Quantity of substance
If internet protocol traffic growth is accommodated by expanding network capacity, then service coverage is improved, but network resource management efficiency deteriorates
Solution Approach 1:
The system dynamically establishes and manages communications bearers across multiple PDNs based on traffic demands and service requirements, allowing network resources to be flexibly allocated and optimized for different internet protocol services rather than using static capacity expansion
