Modified Service User Profile for Mission Critical System Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After a Mission Critical (MC) user migrates to a partner MCPTT system, the user profile parameters refer only to the primary MC system, making it difficult for the MC user to use services in the partner system.
Innovation Solution
An apparatus and method that configure a set of substitute functions and request a service user profile associated with a migration request, creating a modified service user profile with the substitute functions and providing it to enable the MC user to access services in the partner system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MC user profile is migrated to the partner MC system, then the user can access the partner system, but the service usability deteriorates because parameters in the migrated profile refer only to the primary MC system
Solution Approach 1:
The patent applies preliminary action by pre-configuring substitute functions in the service provider apparatus before the MC user migration occurs. When a migration request is received, the system has already prepared the necessary functional alias mappings and substitute functions that will be automatically applied to the migrated user profile, ensuring seamless service continuity in the partner MC system without requiring manual reconfiguration
Solution Approach 2:
The patent introduces substitute functions as an intermediary mechanism between the migrated user profile and the partner MC system. These substitute functions act as a bridge, translating references from the primary MC system parameters into equivalent functionalities in the partner system, allowing the user to access services without direct knowledge of the underlying parameter mappings
2Reliability
If functional aliases are migrated with the user profile, then the user identity is preserved, but service accessibility deteriorates because the aliases reference primary system parameters that don't exist in the partner system
Solution Approach 1:
The patent applies parameter changes by dynamically modifying the functional alias parameters in the migrated user profile. The service provider apparatus detects which parameters in the migrated profile reference the primary MC system and automatically updates them with corresponding parameters from the partner MC system, while preserving the functional identity and role assignments of the user
Solution Approach 2:
The patent segments the user profile into distinct components: immutable identity elements (user ID, role assignments) that are preserved during migration, and mutable parameter elements (functional alias references, system-specific configurations) that are updated to reference the partner system. This segmentation allows selective preservation of identity while enabling parameter adaptation for service accessibility
Data Source
AI summary
There is disclosed an apparatus comprising at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry. The at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least to configure a set of substitute functions. The apparatus is further caused to request a service user profile associated with a migration request. Still further, the apparatus is caused to create, based on the requested service user profile, a modified service user profile comprising the set of substitute functions, and to provide the modified service user profile.
