Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual alteration of network identifiers (APN/DNN) for seamless transition between different networks, such as NPNs and PLMNs, is error-prone and requires user intervention, leading to dissatisfaction and potential connectivity issues.
Innovation Solution
A network management device facilitates automatic network identifier substitution and traffic steering by retrieving subscriber profiles, comparing attributes, and transparently replacing network identifiers to enable seamless access without manual user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual alteration of network identifiers is performed, then network transitions between NPNs and PLMNs can be achieved, but user intervention is required and errors occur
Solution Approach 1:
The network management device automatically retrieves subscriber profiles, compares attributes, and replaces network identifiers without requiring user intervention. The system serves itself by autonomously managing the network transition process, eliminating manual operations and associated errors.
Solution Approach 2:
The subscriber profile is retrieved and analyzed in advance before the network transition occurs. The system prepares the appropriate network identifier replacements beforehand, ensuring seamless transitions without requiring user action during the critical transition moment.
2Adaptability or versatility
If manual alteration of network identifiers is performed, then network transitions can be achieved, but connectivity issues and dissatisfaction result
Solution Approach 1:
The system compares attributes of the retrieved subscriber profile against defined values and uses this feedback to determine whether and how to replace network identifiers. This feedback mechanism ensures accurate, context-appropriate identifier substitution that maintains connectivity reliability.
Solution Approach 2:
The network management device acts as an intermediary between the user equipment and the core network equipment. It transparently handles network identifier replacements, mediating the transition process to ensure reliable connectivity without exposing users to potential errors.
3Ease of operation
If automatic network identifier substitution is implemented, then user experience is enhanced, but system complexity increases
Solution Approach 1:
The network management device performs multiple functions: retrieving subscriber profiles, comparing attributes, determining replacement conditions, and executing identifier substitutions. By consolidating these functions in a single multi-functional system, the patent manages complexity through functional integration rather than proliferation of separate components.

AI summary
Traffic steering for non-public networks and public land mobile network (PLMN) clouds is provided. A method can include retrieving, by a system comprising a processor and associated with a communication network, a subscriber profile for a user equipment in response to receiving a request from the user equipment for access to the communication network, wherein the request comprises first data network information that is distinct from second data network information associated with the communication network; and, in response to an attribute of the subscriber profile being determined to be equal to a defined value, replacing, by the system, the first data network information in the request with the second data network information and routing, by the system, the request to core network equipment of the communication network.
