Network Entity Data Identity Selection for Communication Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems face challenges in handling scenarios where a first data network identity associated with a communications device is not usable, due to factors like network support, policy, or subscription issues, leading to communication failures.
Innovation Solution
A method and apparatus that select a second data network identity usable by the communications device, based on information such as single network slice selection assistance, device capabilities, and service-related data, to facilitate communication by determining the unavailability of the first data network identity and switching to a supported alternative.

Engineering Contradiction Analysis
1Reliability
If the communications device uses the first data network identity as requested, then the device can attempt to establish communication, but the communication fails because the first data network identity is not usable (not supported by network, not permitted by policy or subscription)
Solution Approach 1:
The system changes the data network identity parameter from the originally requested first identity to an alternative second identity that is supported by the network and permitted by policy/subscription constraints, thereby resolving the contradiction between communication reliability and identity compatibility
Solution Approach 2:
The network entity acts as an intermediary between the communications device and the data network, intercepting the requested first data network identity and replacing it with a suitable second identity that satisfies both device requirements and network constraints
2Productivity
If the system automatically selects an alternative data network identity when the first is not usable, then communication can be maintained, but additional complexity is introduced in determining usability and selecting alternatives
Solution Approach 1:
The network entity performs self-service by automatically determining the usability of the requested data network identity and selecting an appropriate alternative without requiring manual intervention or complex external coordination, thus maintaining productivity while managing complexity internally
Solution Approach 2:
The system performs preliminary checks to determine whether the first data network identity is usable before finalizing the communication session, and pre-selects an alternative second identity in advance, preventing communication failures before they occur

AI summary
A method comprises receiving information at a first network entity indicating a first data network identity associated with a request from a communications device; and selecting at the first network entity a second data network identity which is usable with respect to the communications device when said first data network identity is not usable with respect to said communications device, said selecting being in dependence on information associated with said communications device.
