Proximity-Based Sub-Pooling for Wireless Network Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile wireless networks, existing geo-redundant pool configurations face challenges in efficiently selecting the most proximal and low-latency core network nodes for communication, leading to increased signaling impacts and potential network outages due to suboptimal routing.
Innovation Solution
A proximity-based selection algorithm is implemented, which assigns weighting factors to core network nodes based on transport latency, allowing base stations to preferentially communicate with nodes that offer lower latency, thereby creating a sub-pool of proximal nodes for reduced latency and improved resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations communicate with geographically dispersed core network nodes in a geo-redundant pool, then network reliability is improved through geographic isolation, but communication latency increases and signaling efficiency deteriorates
Solution Approach 1:
The geo-redundant pool of core network nodes is segmented into multiple sub-pools based on geographic proximity to base stations. Each sub-pool contains nodes that are geographically close to a specific base station or group of base stations. This segmentation allows the system to maintain the geographic diversity needed for reliability while enabling low-latency communication by selecting the appropriate sub-pool based on the base station's location.
Solution Approach 2:
The patent applies local quality by creating sub-pools with specific geographic characteristics tailored to each base station's location. Instead of treating all core network nodes uniformly, the system identifies and groups nodes that are locally proximate to each base station, thereby optimizing communication latency for each local context while maintaining overall network reliability through the geo-redundant structure.
2Device complexity
If base stations use traditional routing without proximity-based selection, then network simplicity is maintained, but signaling impacts increase and network performance deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-organizing core network nodes into sub-pools based on their geographic locations relative to base stations before actual communication occurs. This pre-segmentation and pre-identification of proximal nodes allows base stations to quickly select the most appropriate sub-pool without complex real-time calculations, thereby improving network performance while keeping the added complexity manageable through structured organization.
3Reliability
If core network nodes are distributed across multiple geographical locations, then fault tolerance is improved, but routing efficiency decreases and network outages may occur due to suboptimal path selection
Solution Approach 1:
The patent introduces dynamics by enabling base stations to adaptively select from multiple sub-pools based on real-time conditions such as node availability, load status, and communication quality. This dynamic selection mechanism allows the system to maintain fault tolerance through geographic distribution while optimizing routing efficiency by choosing the most appropriate sub-pool at each moment, thereby avoiding network outages caused by suboptimal path selection.

AI summary
Aspects of the subject disclosure may include, for example, determining message transfer delays based on transport layer control information associated with network traffic of a backhaul network coupled between a number of core network nodes of a wireless network and a wireless access node of the wireless network. The message transfer delays are representative of the network traffic between the core network nodes and the wireless access node. Weighting factors are assigned to the core network nodes based on the message transfer delays. The weighting factors are exposed to a scheduler that identifies a first group of core network nodes and a second group of core network nodes based on the weighting factors. The wireless access node preferentially establishes communications via the first group of core network nodes. The wireless access node establishes communications via the second group, responsive to an inability to establish communications via any core network nodes the first group. Other embodiments are disclosed.
