ANMC Dynamic Access Identifier Management for 5G Network Slices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5G network access identity management is static and lacks mechanisms for extra-carrier modification, limiting flexibility in assigning or updating access values and network slice access parameters for user equipment (UE) based on customer or enterprise requests.
Innovation Solution
The implementation of an Access Identifier and Network Slice Access Management (ANMC) function, which can be deployed as a virtual function or hardware, allows for dynamic management of access identifiers and network slice access parameters, enabling updates, modifications, and migrations across different networks while maintaining priority and slice access, and supports network-agnostic translation between carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional static access identity management is used, then network simplicity is maintained, but flexibility in assigning or updating access values and network slice access parameters is limited
Solution Approach 1:
The patent implements dynamic access identity management by allowing the network to modify UE access identities and network slice access parameters in real-time based on service requirements, customer requests, and network conditions. This transforms the static SIM-provisioned access identities into dynamically adjustable values without requiring physical SIM changes or complex re-provisioning procedures.
Solution Approach 2:
The patent separates the access identity management into two distinct layers: the static base identity stored in the UE/SIM and the dynamic network-controlled access parameters. This segmentation allows the network to independently modify access values and slice parameters without affecting the core identity structure, thereby increasing flexibility while maintaining system simplicity.
2Reliability
If dynamic access management is implemented, then service access continuity across networks is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the network continuously monitors UE service access status, network conditions, and slice availability. Based on this feedback, the network dynamically adjusts access identities and slice parameters to maintain continuous service access across different networks and carriers, ensuring reliability while managing complexity through automated closed-loop control.
Solution Approach 2:
The patent creates a universal access management framework that works across multiple networks and carriers. The same dynamic access identity management mechanism serves multiple functions: maintaining service continuity during handovers, enabling cross-carrier access, supporting network slicing, and facilitating seamless roaming. This multi-functionality reduces the need for separate complexity-handling mechanisms for each function.
3Adaptability or versatility
If carrier-specific access management is used, then carrier control is maintained, but network-agnostic translation between carriers is limited
Solution Approach 1:
The patent enables network-agnostic translation by dynamically changing access identity parameters based on the target network's requirements. When a UE moves between carriers with different access identity formats or slicing schemes, the serving network translates the access parameters to match the target network's expectations, maintaining carrier control while enabling seamless inter-carrier operation through parameter adaptation.
Data Source
AI summary
An access identifier and network slice access management component (ANMC) is disclosed. The ANMC can receive service access update information from an entity, for example a customer/enterprise, that be used to update service access of a user equipment (UE) to services of a network. Embodiments of the ANMC can facilitate updating an access identity parameter, updating an access priority parameter, updating a network slice access parameter, or combinations thereof. An ANMC can be embodied in a virtualized network function, as hardware, as software, or combinations thereof. An ANMC can be local to a network supporting the UE or can be located remotely from the network supporting the UE, such as in execution on a server of a cloud platform. The ANMC can support management of UE service access by an entity other than a carrier supporting the UE via a device external to a network of the carrier.
