UE Policy Delivery via Hardware Layer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and poor extensibility of existing policy delivery and execution processes in 3GPP communications systems, particularly due to the requirement for operating system and application layer support in user equipment (UE), make it difficult to unify and extend policy management across different manufacturers and terminals.
Innovation Solution
A data transmission method that separates the UE hierarchy into application, operating system, and hardware layers, allowing the hardware layer to receive and execute policies independently of the operating system, using dedicated transport channels and non-access stratum signaling to transmit policies and reports, thereby simplifying the process and improving extensibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If policy delivery is implemented through operating system and application layer support in UE, then policy execution capability is achieved, but implementation complexity increases and extensibility deteriorates
Solution Approach 1:
The patent segments the UE architecture into distinct layers (application layer, operating system layer, and hardware layer). The policy delivery function is specifically assigned to the hardware layer, separating it from the operating system and application layers. This segmentation allows policy execution to be achieved through dedicated hardware components while reducing overall implementation complexity and improving extensibility across different manufacturers and terminals.
2Reliability
If policy delivery uses operating system and application layer support, then policy execution is enabled, but unified upgrading and extension become difficult
Solution Approach 1:
By segmenting the UE into layered architecture with policy delivery isolated at the hardware layer, the patent enables independent upgrading and extension of policy functions without affecting the operating system or application layers. This allows for unified implementation across different manufacturers while maintaining the ability to extend functionality.
Solution Approach 2:
The patent introduces a dedicated hardware layer as an intermediary between the network and the upper layers (OS and applications). This intermediary handles policy delivery independently, using hardware-specific mechanisms (such as dedicated memory areas, interrupt controllers, or boot-time initialization) that are transparent to the OS and applications, thereby enabling unified upgrading and extension.
3Adaptability or versatility
If policy delivery is implemented at application layer, then policy functionality is achieved, but the process becomes complex and manufacturer-specific
Solution Approach 1:
The patent segments policy delivery functionality from the application layer and places it at the hardware layer. This segmentation simplifies the overall process by eliminating the need for complex application-layer implementations while maintaining policy functionality. The hardware layer handles policy delivery through standardized mechanisms that are simpler to implement and operate across different manufacturers.
Data Source
AI summary
A data transmission method, a terminal, and an access-network network element are disclosed. An interface is disposed on a policy client of UE and an operating system or an application layer of the UE. The interface is used to provide the operating system or the application layer with a policy related to the operating system or the application layer, and collect, from the operating system or the application layer, information required for a report. In this way, a dedicated transport channel is implemented by a bottom layer of the UE, reports and policies are transmitted on the dedicated transport channel, and during implementation, a protocol is not coupled with the application layer or the operating system, so that the system is simple to implement.
