UDM Service Parameter Override for Wireless Network Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Unified Data Management (UDM) in wireless communication networks faces inefficiencies in retrieving and transferring user context for wireless user devices, particularly in updating service parameters and responding to network requirements, leading to rigid service configurations that are difficult to manage effectively.
Innovation Solution
The UDM identifies provisioned service values, retrieves updated values, generates new provisioned service values by overriding the existing ones, and transfers these new values to the network controller, enabling efficient service updates and improved network responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the UDM uses rigid service parameters that are difficult to update, then service configuration stability is maintained, but service adaptability and responsiveness to network requirements deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the UDM to transition from static, rigid service parameters to dynamic, updateable service parameters. The system allows service parameters to be modified in real-time based on network requirements and user context changes, making the previously fixed configuration adaptable while maintaining operational stability through controlled update mechanisms.
Solution Approach 2:
The patent directly implements parameter changes by allowing the UDM to retrieve updated service values and override existing provisioned service values. This enables flexible modification of service parameters such as QoS settings, data network names, and other service characteristics without requiring rigid, difficult-to-update configurations.
2Device complexity
If the UDM retrieves and transfers user context inefficiently, then system simplicity is maintained, but service update speed and network responsiveness deteriorate
Solution Approach 1:
The patent applies preliminary action by having the UDM proactively retrieve updated service values from the UDR before service updates are needed. By pre-fetching and storing updated service parameters, the system reduces the time required for actual service updates while maintaining a relatively simple architecture without complex real-time synchronization mechanisms.
Solution Approach 2:
The patent uses copying by creating and transferring copies of user context data between the UDM, UDR, and network controller. Instead of maintaining complex real-time links, the system efficiently replicates service parameter data across network elements, enabling fast service updates through data duplication rather than sophisticated coordination protocols.

AI summary
A wireless communication network serves a wireless data service to a wireless User Equipment (UE). In the wireless communication network, a network controller receives a service request from the wireless UE. The network controller responsively indicates the service request to a Unified Data Management (UDM). The UDM receives the indication. The UDM identifies provisioned service values for the wireless UE. The UDM retrieves updated service values for the wireless UE. The UDM identifies a set of the provisioned service values that correspond to the updated service values. The UDM generates new provisioned service values by overriding the set of the provisioned service values based on the updated service values. The UDM transfers new provisioned service values to the network controller. The network controller receives the new provisioned service values. The network controller serves the wireless UE based on the new provisioned service values.
