Vehicle-Based Mobile SDN Nodes for Network Coverage Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication networks face challenges in efficiently deploying network services to mobile endpoints due to sparse coverage areas and limitations in bandwidth and connectivity, especially when mobile devices are outside traditional wireless communication ranges.
Innovation Solution
The implementation of vehicle-based mobile SDN nodes that can be dynamically configured and reconfigured to provide various network services by extending the software-defined network (SDN) architecture to include vehicles equipped with mobile SDN nodes, which can act as temporary network infrastructure, providing services such as voice calls, video streaming, and data access by coinciding with the routes of mobile endpoint devices.

Engineering Contradiction Analysis
1Area of stationary object
If network services are deployed using traditional fixed infrastructure, then service coverage is stable and reliable, but coverage area is limited and cannot reach sparse or mobile areas
Solution Approach 1:
The patent transforms the static network infrastructure into a dynamic system by deploying services on mobile vehicles. The vehicle-based mobile nodes can move to different locations to provide network services, enabling coverage in sparse and remote areas while maintaining service reliability through coordinated movement and network connectivity.
Solution Approach 2:
The patent extends network coverage from a two-dimensional fixed ground infrastructure to a three-dimensional mobile platform. By mounting network service nodes on vehicles, the system adds the dimension of mobility, allowing services to reach areas that are geographically distant or inaccessible to fixed infrastructure.
2Area of stationary object
If network services are deployed on vehicle-based mobile nodes, then network coverage is extended to sparse areas and latency is reduced, but device complexity increases
Solution Approach 1:
The vehicle-based mobile nodes are designed as universal platforms that can host multiple network services (e.g., caching, edge computing, content delivery). This multi-functionality reduces the need for separate specialized devices for each service, thereby managing complexity while providing diverse network capabilities in mobile deployments.
Solution Approach 2:
The patent introduces a controller as an intermediary that manages the deployment and coordination of services on vehicle-based mobile nodes. This centralized control mechanism simplifies the complexity by abstracting the management of mobile resources, allowing automated service placement and resource allocation without requiring complex peer-to-peer coordination among vehicles.
3Productivity
If services are assigned to vehicle-based mobile nodes based on route coincidence, then service delivery efficiency is improved and bandwidth is conserved, but routing determination complexity increases
Solution Approach 1:
The system performs preliminary route determination and service assignment before actual service delivery. By predicting vehicle routes and pre-assigning services to appropriate mobile nodes based on anticipated route coincidences, the system optimizes service delivery efficiency and reduces real-time decision-making complexity.
Solution Approach 2:
The patent implements feedback mechanisms where the controller continuously monitors vehicle locations, routes, and service performance. This feedback enables dynamic adjustment of service assignments and route predictions, improving service delivery efficiency while managing complexity through adaptive control rather than static complex algorithms.

AI summary
Devices, computer-readable media, and methods are disclosed for assigning a service to a vehicle-based mobile node. For example, a processor deployed in a communication network may receive a request for the service from a mobile endpoint device, determine a route of the mobile endpoint device, determine a route of the vehicle-based mobile node, and assign the service to the vehicle-based mobile node when the route of the mobile endpoint device and the route of the vehicle-based mobile node coincide.
