Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless Wide Area Networks (WWANs) face bottlenecks in access links due to increased traffic from multimedia applications, leading to unsatisfactory user experiences.
Innovation Solution
A multipath overlay network is implemented, where nodes can discover helpers to establish multiple paths for multimedia communication sessions, utilizing label switching mechanisms and protocol stacks to route substreams, enhancing quality of service by utilizing additional bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single access link is used for multimedia communication, then the network structure remains simple, but the bandwidth is insufficient and user experience deteriorates
Solution Approach 1:
The patent segments the communication path by introducing multiple helper nodes (first helper, second helper, etc.) that create alternative routing paths. Each helper node handles specific segments of the multimedia data flow, effectively dividing the bandwidth requirement across multiple links rather than relying on a single access link.
Solution Approach 2:
Helper nodes are introduced as intermediary elements between the base station and terminal. These helpers receive, process, and forward multimedia data through alternative paths, mediating the traffic flow to utilize additional bandwidth while maintaining network structure manageability.
2Reliability
If multiple paths are established for multimedia communication, then the bandwidth increases and quality of service improves, but the protocol complexity and signaling overhead increase
Solution Approach 1:
The patent implements preliminary path setup through helper join requests and path establishment procedures before actual multimedia communication begins. The base station pre-configures multiple helper nodes with their respective paths, so when communication starts, the reliable multi-path infrastructure is already in place, reducing real-time complexity.
Solution Approach 2:
The patent adds a new dimension to the network architecture by introducing a helper layer between the base station and terminal. This additional network dimension provides alternative routing paths without fundamentally complicating the existing access link structure, allowing QoS improvement while managing protocol complexity through layered design.
3Productivity
If helper nodes are introduced to create multiple paths, then additional bandwidth is utilized and bottlenecks are reduced, but the network configuration and management become more complex
Solution Approach 1:
Helper nodes automatically perform path setup and management functions through standardized join requests and response mechanisms. The base station systematically configures helpers using predefined protocols, reducing manual configuration complexity while enabling scalable deployment of multiple paths for enhanced data transmission capacity.
Data Source
AI summary
A method, a computer program product, and an apparatus are provided. The apparatus, which is a first node, sends a join request to a second node to route communication associated with a third node to the first node. The join request includes a first node identifier associated with the first node. The first node receives from the second node a join response comprising a second node identifier associated with the second node. The first node sends a setup request to the third node, the setup request comprising the second node identifier. The first node receives a communication with the first node identifier from the second node, the communication originating from the third node.
