Private Network Traffic Routing for Remote Core Network Outages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In private networks, users without authorization to access the operator's core network face service disruptions due to congestion or network issues, leading to loss of network access and service availability.
Innovation Solution
A private network traffic optimization service that reroutes unauthorized users' traffic through the private network's core network, utilizing monitoring, analytics, and rerouting services to optimize resource use and enable access via a roaming configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users without authorization access the operator's core network, then network service availability is improved, but network congestion and service disruptions occur
Solution Approach 1:
The network access is segmented into authorized and unauthorized user paths. Unauthorized users are routed through the private network's core network separately from the operator's core network, allowing both segments to operate independently without interfering with each other's performance and reliability.
Solution Approach 2:
The private network's core network acts as an intermediary for unauthorized users. Instead of directly accessing the operator's core network, unauthorized users are routed through the private network's core, which mediates their access and prevents direct congestion of the operator's core network resources.
2Object-affected harmful factors
If unauthorized users are completely blocked from the operator's core network, then network congestion is reduced, but service availability is lost for users who need access
Solution Approach 1:
The routing parameters are changed dynamically based on user authorization status. Authorized users continue to access the operator's core network directly, while unauthorized users have their routing parameters modified to go through the private network's core, optimizing resource utilization for both groups.
Solution Approach 2:
The network routing is made dynamic rather than static. The system continuously monitors user authorization status and network conditions, adjusting routing paths in real-time to ensure unauthorized users receive service through alternative paths while preventing congestion on the operator's core network.
3Reliability
If all users are routed through the private network's core network, then service availability is improved, but network resource efficiency decreases
Solution Approach 1:
Different routing quality is applied to different user groups based on their authorization status. Authorized users receive direct, high-efficiency routing to the operator's core network, while unauthorized users receive routed access through the private network's core, optimizing resource efficiency for each local group appropriately.
Solution Approach 2:
The private network's core network serves multiple functions: it acts as the primary core for authorized users and as an alternative routing path for unauthorized users. This multi-functionality allows the system to maintain service availability for all users while preserving network resource efficiency by not forcing all traffic through the private core.

AI summary
A method, a network device, and a non-transitory computer-readable storage medium are described in relation to a private network traffic optimization service. The service may be implemented in a private network. The service may include analyzing context information pertaining to a remote core network relative to a private network in which some users may not be authorized to use a core network of the private network. The service may detect when the remote core network may be unreachable based on the analysis. The service may include analyzing context information pertaining to the core network of the private network. The service may disable routing of traffic associated with the users and enable use of the core network based on a roaming configuration, a roaming core network, and an excess capacity of the core network.
