Network Policy Interface for Cellular Traffic Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connecting user devices to cellular networks for data transmission increases network traffic, and existing solutions fail to effectively manage policies to optimize user experience and reduce conflicts.
Innovation Solution
Implementing a system where user devices receive a single set of policies from a cellular network when connecting to a local area network (LAN), using an interface between a policy device and a LAN selecting device, to direct the user device to connect to a network with lower traffic and set bandwidth limits, thereby reducing cellular network traffic and eliminating policy conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user devices connect to cellular networks to send and receive data, then user experience is improved through network connectivity, but cellular network traffic increases
Solution Approach 1:
The patent introduces a local area network (LAN) as an intermediary between user devices and the cellular network. User devices connect to the cellular network through the LAN, which acts as a mediator to reduce direct cellular network traffic while maintaining connectivity. The LAN provides local routing and policy enforcement capabilities, allowing data to be transmitted locally without always traversing the cellular network.
2Adaptability or versatility
If multiple policies are provided to user devices from different networks, then policy coverage is improved, but policy conflicts increase
Solution Approach 1:
The patent segments policy management into separate functional components: a policy device that creates and manages policies, and a LAN selecting device that receives and enforces policies. This segmentation allows policies to be defined centrally while being applied locally, ensuring consistency across multiple networks without conflicts. The policy device maintains a single source of truth for policy definitions.
Solution Approach 2:
The LAN selecting device acts as an intermediary between the cellular network and user devices for policy delivery. It receives policies from the policy device and enforces them consistently, preventing policy conflicts by ensuring that only authorized policies are applied to user devices regardless of which network they connect to.
3Device complexity
If user devices connect directly to cellular network, then policy delivery is simplified, but network traffic increases
Solution Approach 1:
The patent introduces a LAN selecting device as an intermediary in the policy delivery path. Instead of direct communication between the cellular network and user devices, policies are delivered through the LAN selecting device, which reduces cellular network traffic by handling policy management locally at the LAN level while maintaining simplified delivery mechanisms.

AI summary
A first device is configured to store network load information regarding one or more network devices connected to the first device. Each one of the one or more network devices may have a connection range. The first device is further configured to receive information regarding a second device. The information regarding the second device may include information identifying a network device, of the one or more network devices, in which the second device is within connection range of and network load information regarding the network device in which the second device is within connection range of. The first device is further configured to provide the information regarding the second device to a third device; receive, from the third device, a first policy based on providing the information regarding the second device to the third device; and provide the first policy to the second device.
