Unconstrained UE Gateway for MSGin5G Protocol Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not provide a method for exchange of messages between constrained UEs and unconstrained UEs in the MSGin5G service, nor do they specify how a gateway UE can identify and forward messages to constrained UEs, and they lack protocol translation capabilities between different communication protocols used by constrained and unconstrained UEs.
Innovation Solution
An unconstrained UE operates as a message relay/gateway for constrained UEs, enabling registration and communication with a MSGin5G server through a protocol translation mechanism, utilizing an application layer interface (MSGin5G-6) and a gateway controller for authorization and message handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If constrained UEs use gateway UEs to communicate with MSGin5G server, then communication capability is improved, but system complexity increases due to protocol translation requirements
Solution Approach 1:
The patent introduces a gateway UE as an intermediary component that bridges constrained UEs and the MSGin5G server. The gateway UE performs protocol translation between CoAP (used by constrained UEs) and HTTP/SIP (used by unconstrained UEs and server), eliminating the need for constrained UEs to directly support complex protocols while enabling their communication capability.
Solution Approach 2:
The gateway UE is designed with multi-functionality to handle multiple protocol types (CoAP, HTTP, SIP) and serve both constrained and unconstrained UEs. This universal design allows a single gateway component to manage diverse communication needs, reducing overall system complexity despite the added translation capabilities.
2Adaptability or versatility
If protocol translation is implemented between constrained and unconstrained UEs, then communication compatibility is improved, but processing overhead increases
Solution Approach 1:
The patent extracts the protocol translation function from individual UEs and concentrates it in the gateway UE. By removing translation complexity from constrained UEs and placing it in a dedicated gateway, the system reduces processing overhead at the edge devices while maintaining communication compatibility across different protocol types.
3Reliability
If constrained UEs register with gateway UE for message exchange, then message delivery capability is improved, but registration management complexity increases
Solution Approach 1:
The gateway UE autonomously manages the registration process for constrained UEs without requiring direct intervention from the MSGin5G server or manual configuration. Constrained UEs simply send registration requests to the gateway, which automatically handles authentication, protocol translation setup, and message routing, thereby simplifying registration management while ensuring reliable message delivery.

AI summary
The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for communication of a constrained user equipment (UE) with a Message in Fifth Generation (MSGin5G) server providing a MSGin5G service in an IoT network is provided. The method includes receiving, by an unconstrained UE, a registration request comprises a security credential of the constrained UE from the constrained UE, where the unconstrained UE have access to the MSGin5G server and the constrained UE do not have access to the MSGin5G server. The method includes determining, by the unconstrained UE, whether the constrained UE is authorized based on the security credential. The method includes performing, by the unconstrained UE, a registration of the constrained UE with the unconstrained UE for communication of the constrained UE with the MSGin5G server based on authorization of the constrained UE.
