Edge Core Subscriber Management for Low-Latency Enterprise Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks lack a local core network, leading to increased latency and complexity in managing diverse user services and subscriber authentication, especially in enterprise environments where seamless integration of various cellular technologies is required.
Innovation Solution
Implementing a locally placed edge core network with a single sign-on service that allows different services to be used by different users, integrated with Open connect Providers (OP) and Access Points (AP), enabling scalable user control and enterprise-specific policies, and supporting multiple operator networks through shared spectrum and cloud-based mobility management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a remote core network is used, then network infrastructure is simplified, but latency increases and service provisioning becomes less efficient
Solution Approach 1:
The patent segments the core network into distributed edge core network elements deployed locally at enterprise sites. Each edge core network element handles subscriber management and service provisioning independently, eliminating the need for all traffic to traverse a remote core network, thus reducing latency while maintaining infrastructure simplicity.
Solution Approach 2:
The patent introduces a new spatial dimension by deploying core network functions at the edge (local dimension) rather than only at a centralized remote location. This multi-dimensional network architecture allows subscribers to access services through the nearest edge core network element, reducing transmission distance and latency.
2Adaptability or versatility
If multiple cellular technologies are integrated, then service versatility improves, but system complexity increases
Solution Approach 1:
The edge core network element is designed as a universal platform that can simultaneously support multiple cellular technologies (4G, 5G, Wi-Fi 6) and different service types (voice, data, IoT). This multi-functional design allows a single system to handle diverse services without requiring separate dedicated systems for each technology, thereby improving versatility while controlling complexity.
Solution Approach 2:
The edge core network element acts as an intermediary that abstracts the complexity of multiple cellular technologies from end users and applications. It provides a unified interface and common subscriber management layer that simplifies access to diverse services across different technologies, hiding the underlying system complexity.
3Reliability
If centralized subscriber management is used, then security is simplified, but access control flexibility decreases
Solution Approach 1:
The patent segments subscriber management functions by deploying local edge core network elements at distributed locations. Each edge core network element maintains local subscriber data and authentication capabilities, enabling decentralized security management. This segmentation allows enterprises to implement location-specific access control policies while maintaining overall security through standardized authentication protocols.
Solution Approach 2:
The patent implements local quality by allowing each edge core network element to have customized subscriber management and access control policies tailored to specific enterprise needs and locations. Different enterprises or departments can have different authentication methods, service permissions, and access control rules locally, providing flexibility while maintaining security through consistent core principles.
