Multi-Operator Anchor Service Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in deploying Fifth Generation (5G) and beyond networks lies in efficiently creating connections between multiple operator core networks and edge computing environments due to limited space and complexity in communicating with multiple operator core networks.
Innovation Solution
A multi-operator anchor service is implemented using a core network device that includes a user plane function (UPF) and packet data network gateway (PGW), providing connectivity between end devices and application service layer networks, thereby eliminating the need for each operator to deploy their own anchor device and connectivity with radio access networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each operator deploys their own anchor device and connectivity with radio access networks, then operator-specific connectivity is ensured, but device complexity and deployment complexity increase
Solution Approach 1:
The patent combines multiple operator core network connections into a single multi-operator anchor device. This device provides centralized connectivity to multiple radio access networks simultaneously, eliminating the need for separate anchor devices for each operator while maintaining operator-specific connectivity through logical separation of connections.
Solution Approach 2:
The multi-operator anchor device is designed to perform multiple functions by supporting connections to multiple operator core networks and multiple radio access networks. This universal device replaces several specialized anchor devices, reducing overall system complexity while ensuring each operator maintains reliable connectivity through dedicated logical interfaces.
2Reliability
If multiple anchor devices are deployed for multiple operators, then operator connectivity is ensured, but space requirements and infrastructure complexity increase
Solution Approach 1:
The patent merges multiple operator core network connections and radio access network interfaces into a single physical anchor device location. This consolidation reduces the physical space required compared to deploying separate anchor devices for each operator, while maintaining reliable connectivity through virtualized network functions and logical connection separation.
3Device complexity
If centralized connectivity solution is implemented, then deployment complexity is reduced, but adaptability to different operator requirements may be limited
Solution Approach 1:
The patent segments the centralized multi-operator anchor device into logical interfaces and connection paths for each operator. This allows the physical device to remain centralized and simple to deploy, while each operator's specific requirements are met through dedicated logical configurations, routing rules, and network function virtualization instances.
Solution Approach 2:
The system employs dynamic configuration capabilities where the centralized anchor device can adapt to different operator requirements through software-defined networking and virtualized network functions. Connection parameters, routing policies, and service configurations can be dynamically adjusted to meet varying operator needs without changing the physical infrastructure.
