Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of data services with voice services in licensed wireless networks leads to increased demand and burden on network resources, resulting in reduced access speed and quality due to inefficiencies in data routing and encapsulation processes, particularly when interfacing with external networks like the Internet.
Innovation Solution
The implementation of an integrated communication system (ICS) that allows seamless voice and data services across licensed wireless networks by using a modified interface for direct communication with components of the network, bypassing non-essential components like the SGSN to reduce latency and overhead, and utilizing direct tunneling protocols like Gn' for efficient data packet transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data services are integrated into licensed wireless networks using traditional routing components, then service functionality is provided, but network latency increases and data transmission speed decreases
Solution Approach 1:
The patent extracts and removes non-essential network components (specifically the SGSN - Serving GPRS Support Node) from the data transmission path. By eliminating this intermediate component, data packets can travel directly from the access network to the core network gateway, significantly reducing processing delays and network latency while maintaining all necessary service functionality.
Solution Approach 2:
The patent segments the network architecture into distinct functional components: access network, core network gateway, and optional caching elements. This segmentation allows data to bypass unnecessary intermediate processing stages and travel through optimized direct paths, improving transmission speed while maintaining service integrity through clearly defined interface protocols.
2Adaptability or versatility
If multiple encapsulation layers are used for data routing between different network types, then interoperability is achieved, but overhead increases and bandwidth efficiency decreases
Solution Approach 1:
The patent applies partial encapsulation by implementing only the essential protocol layers needed for interoperability between unlicensed and licensed networks. Rather than using full multi-layer encapsulation, the solution uses selective protocol adaptation at critical interfaces, reducing overhead while maintaining sufficient adaptability for cross-network communication.
Solution Approach 2:
The patent changes the protocol parameters and format of data packets dynamically based on the target network type. By adapting packet structure, addressing format, and protocol headers to match the requirements of the destination network, the system achieves broad interoperability without requiring excessive encapsulation layers, thus reducing bandwidth overhead.
3Productivity
If existing network infrastructure is used without modification, then deployment cost is reduced, but service quality and efficiency cannot be improved
Solution Approach 1:
The patent designs the core network gateway with multi-functional capabilities that can handle both traditional routed data traffic and direct-tunneled data traffic from unlicensed networks. This universal gateway architecture allows the system to improve service efficiency through direct tunneling while maintaining compatibility with existing network infrastructure and traffic types, avoiding the need for completely separate parallel systems.
Solution Approach 2:
The patent introduces an optional data cache as an intermediary element between the access network and core network gateway. This cache serves multiple functions: buffering data during network transitions, pre-fetching content to reduce latency, and providing local storage to offload the core network. The intermediary enhances service quality and efficiency while maintaining relative simplicity by adding only one strategic component rather than complex multi-component systems.
