LwM2M Client Identity for Seamless Multi-UE Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in providing a seamless and hassle-free access to operator services across multiple user equipment (UE) devices, as they often require separate registrations and identities, lacking a unified federated identity management system.
Innovation Solution
Implementing a client-identify mechanism using the Lightweight Machine-to-Machine (LwM2M) protocol to provide a unified identity for UE devices, allowing users to access services with a single identity across multiple devices, supporting Single Sign-On (SSO)-like experiences and enabling seamless access without additional user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate registrations and identities are required for each UE device, then service security and device-specific authentication are improved, but user convenience and access simplicity deteriorate
Solution Approach 1:
The patent merges multiple device-specific identities into a single unified federated identity that works across all UE devices. The identity manager combines user credentials with device identifiers to create a unified identity structure, allowing seamless authentication across multiple devices without requiring separate registrations for each device.
Solution Approach 2:
The federated identity system provides universal access across different device types and service platforms. The unified identity can be used for accessing operator services on any UE device, making the authentication system multi-functional and device-agnostic while maintaining security requirements.
2Adaptability or versatility
If multiple usernames and passwords are required for different devices, then device-specific access control is improved, but system complexity and user management burden increase
Solution Approach 1:
The identity manager acts as an intermediary between the user and multiple service providers across different devices. It handles the complexity of managing multiple identities by providing a single point of authentication, translating user credentials into appropriate device-specific access tokens without exposing the underlying complexity to the user.
Solution Approach 2:
The system segments the identity management functionality into a separate identity manager component that operates independently from individual UE devices and service providers. This segmentation allows the complex identity management logic to be centralized while keeping individual device implementations simple.
3Reliability
If separate authentication processes are used for each service, then service-specific security requirements are met, but access time and user effort increase
Solution Approach 1:
The system performs preliminary authentication by establishing a unified federated identity in advance that can be reused across multiple services and devices. Instead of authenticating separately for each service, the user's identity is pre-established and recognized across the federated system, enabling rapid access without repeated authentication processes.
Solution Approach 2:
The identity manager provides feedback mechanisms to service providers about user authentication status and credentials. This allows service providers to quickly verify user identity without requiring full authentication processes, reducing access time while maintaining security through informed decision-making.

AI summary
For example, a User Equipment (UE) may be configured to generate a client identity element including a user identifier (ID) and a device ID, the user ID based on an identity of a user of the UE, the device ID based on a device identifier of the UE; transmit a registration message from the UE to a device management server to register the UE, the registration message including the client identity element; and transmit a service request to a service provider to initiate access of the UE to a service of the service provider, wherein the service request includes the client identity element.
