MC Server Security Domain Access for Migrated Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to provide end-to-end security for communication between mission critical (MC) service users when a user migrates from a primary system to a partner system, leading to potential unauthorized access and security breaches.
Innovation Solution
A method and device for managing security domain access information, involving a first MC server that generates and transmits a private call redirection message with security domain access information to establish secure communication with a migrated user, verifying migration permissions through configuration documents and service authorization requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user migration from primary system to partner system is implemented, then service versatility and adaptability are improved, but security reliability deteriorates due to potential unauthorized access and security breaches
Solution Approach 1:
The patent introduces a security domain access information management mechanism as an intermediary between the primary and partner systems. This intermediary manages security domain access information to ensure that migrated users maintain secure communication channels while accessing services across system boundaries, thus resolving the contradiction between migration versatility and security reliability
Solution Approach 2:
The patent implements preliminary verification of migration permissions through configuration documents and service authorization requests before allowing user migration. This preliminary action ensures that only authorized migrations occur, maintaining security reliability while enabling versatile user mobility across systems
2Reliability
If security domain access information is managed during user migration, then security reliability is improved, but device complexity increases due to additional verification and redirection mechanisms
Solution Approach 1:
The patent designs the security domain access information management mechanism to serve multiple functions: verifying migration permissions, managing security domain access, and coordinating communication between primary and partner systems. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while improving security
Solution Approach 2:
The patent implements feedback mechanisms through configuration documents and service authorization requests that continuously verify migration permissions and security domain access. This feedback loop ensures security reliability while automating the verification process, reducing manual complexity and improving system reliability
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method and a first mission critical (MC) server are provided for managing security domain access information of migrated users in a private communication in MC services. A first MC server receives a private call request from an MC service user of a first UE for establishing the private communication with an MC service user of a second UE. It is determined whether the MC service user of the second UE is migrated from the first MC server to at least one secondary MC server. A private call redirection message is generated, and the private call redirection message is transmitted to the MC service user of the first UE to establish the private communication with the MC service user of the second UE based on the private call redirection message.
