UE Aggregation Gateway Clustering for 5G Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of non-3GPP UE devices connecting to 5G networks strains the operator core network resources, leading to potential limitations in providing services and disincentives for network operators to allow further access, as each device requires individual registration and authentication, consuming significant processing, memory, and network bandwidth.
Innovation Solution
Implementing a UE aggregation gateway that clusters multiple UE devices into a single logical entity, allowing them to register and interact with the network as a single device, thereby reducing the computational overhead and resource consumption by consolidating their activities under a single registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each non-3GPP UE device registers individually with the 5G network, then network service access is provided to each device, but network resources (processing, memory, bandwidth) are excessively consumed
Solution Approach 1:
Multiple non-3GPP UE devices are merged into a single UE cluster represented by one UE logical entity. The UE aggregation gateway consolidates individual device registrations into a single cluster registration, reducing network resource consumption while maintaining service access for all member devices.
Solution Approach 2:
The UE aggregation gateway acts as an intermediary between non-3GPP UE devices and the 5G network. It manages device clustering, handles registration/authentication for the entire cluster as a single entity, and mediates network interactions, thereby reducing the burden on core network resources.
2Productivity
If more non-3GPP UE devices are allowed to connect to the 5G network, then network utility and data usage increase, but the operator core network becomes overwhelmed
Solution Approach 1:
Devices are merged into clusters where multiple UE devices share a single UE logical entity registration. This allows the network to support more devices by treating them as consolidated units, increasing network utility without proportionally increasing core network load.
Solution Approach 2:
The UE aggregation gateway provides multi-functional capabilities: it manages device clustering, handles registration/authentication, routes data traffic, and maintains device-to-cluster mappings. This universal gateway function enables efficient management of large numbers of devices through a single network entity.
3Reliability
If individual registration and authentication is performed for each UE device, then network security is maintained, but processing overhead and authentication time increase
Solution Approach 1:
Authentication operations are merged at the cluster level rather than individual device level. The UE aggregation gateway performs single authentication for the entire UE cluster, reducing authentication time while maintaining security through the gateway's trusted position in the network architecture.
Solution Approach 2:
The UE aggregation gateway performs preliminary clustering and registration of devices before they need network access. By pre-establishing the UE logical entity and cluster membership, the system eliminates repeated individual authentication processes, reducing authentication time while maintaining security through the gateway's centralized management.

AI summary
Systems and methods for user equipment clusters for network registration and authentication are provided. In some embodiments, a UE aggregation gateway may define one or more UE clusters from a set of UE devices that have connected to an access network. In some embodiments, the UE aggregation gateway may register a UE logical entity with the network and associate a cluster of UE devices with that UE logical entity. The UE aggregation gateway may then function as a proxy gateway for members of the UE cluster, acting on behalf of the members of the UE cluster at least with regard to operations with functions of the operator network core.
