APN Authorization Method Using Access Network Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, operators cannot appropriately control the Access Point Name (APN) that user equipment (UE) is allowed to authorize, especially when determining APN authorization, as the current methods do not consider the type of access network the UE is connected to.
Innovation Solution
A method and system that determine whether an APN is authorized by identifying the target APN and the type of access network the UE is currently using, and comparing this information to authorized access network types, allowing operators to control APN access based on the access network type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the AAA server determines APN authorization based only on subscription data without considering access network type, then the authorization process is simple, but operators cannot appropriately control APN access by access network type
Solution Approach 1:
The authorization determination is segmented into multiple independent checking steps: first checking if the APN is in the subscription data, then separately checking if the access network type matches the authorized network type for that APN. This segmentation allows operators to control APN access by network type while keeping each individual check relatively simple.
Solution Approach 2:
The patent performs preliminary checks before final authorization: first verifying the APN exists in subscription data, then checking the access network type authorization. This preliminary action structure ensures that operators can implement fine-grained control without overwhelming complexity in a single authorization step.
2Adaptability or versatility
If the system checks both APN inclusion in subscription data and access network type authorization, then operators can appropriately control APN access, but the authorization determination process becomes more complex
Solution Approach 1:
The dual-check authorization process is divided into distinct segments: Step 1 checks APN inclusion in subscription data, Step 2 checks access network type authorization. Each segment handles a specific aspect of authorization, making the overall complex process manageable through clear separation of concerns.
Solution Approach 2:
The authorization process dynamically adapts to different scenarios: if the APN is not in subscription data, authorization fails immediately; if the APN is present, the system then dynamically checks network type authorization. This dynamic approach allows precise control while optimizing the authorization flow based on actual conditions.

AI summary
Embodiments of the present disclosure provide an access point name (APN) authorization method, apparatus, and system. The APN authorization method includes: determining, by a network device, a target APN of user equipment UE and a type of an access network that the UE currently accesses; obtaining, by the network device, information about an authorized access network type corresponding to the target APN of the UE; and determining, by the network device according to the type of the access network that the UE currently accesses and the information about the authorized access network type corresponding to the target APN of the UE, whether the target APN of the UE is authorized. In the present disclosure, when APN authorization determining is performed, an operator can appropriately control the APN which the UE is allowed to access.
