UE Policy Section Identifier for Accurate Type Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User Equipment (UE) faces challenges in distinguishing specific policy types when receiving UE policies divided into sections, as existing methods lack clear identification mechanisms for policy types corresponding to each section.
Innovation Solution
The UE receives additional information, such as policy type indicators or service attributes, to determine the policy type, allowing it to request specific policy updates from the network side, thereby enabling pertinent policy updates based on recognized policy types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network divides UE policy into multiple sections for transmission, then the policy transmission becomes more organized and manageable, but the UE cannot distinguish the specific policy type corresponding to each section
Solution Approach 1:
The patent embeds a Policy Section Identifier (PSI) within each policy section, creating a nested structure where the identifier is contained inside the section it describes. This allows the UE to access policy type information directly from within each section without requiring external mapping tables or additional communication overhead.
Solution Approach 2:
The PSI acts as an intermediary element that bridges the gap between the divided policy sections and the UE's policy type recognition capability. By inserting this identifier as a mediator within each section, the system enables the UE to correctly interpret and distinguish between different policy types (e.g., V2X policy, URSP) without requiring complex external reference mechanisms.
2Ease of operation
If the UE requests policy updates without knowing the specific policy type, then the request process is simplified, but the network cannot provide targeted policy updates for specific policy types
Solution Approach 1:
The patent implements preliminary action by pre-embedding the PSI within each policy section before transmission to the UE. This allows the UE to have the policy type identification information ready in advance, enabling it to make informed and specific policy update requests without requiring complex real-time determination processes or risking inaccurate updates.
3Adaptability or versatility
If the UE stores multiple mapping relations between user ID and PSI, then the UE can recognize policy types for multiple users, but the device complexity and memory requirements increase
Solution Approach 1:
The patent extracts the policy type identification function from external mapping tables and user ID associations, and places it directly within each policy section through the PSI. This eliminates the need for the UE to store and manage complex mapping relations between user IDs and PSIs, while still enabling multi-user and multi-policy type recognition capabilities.

AI summary
The embodiments of the present disclosure provide a method and device for policy determination and User Equipment (UE). The method includes that: a UE receives first information transmitted by a network device, here, the first information includes at least one of: a first policy, a policy type corresponding to the first policy, a service type corresponding to the first policy, indication information indicative of whether the UE is allowed to request the first policy, or a trigger condition for the UE to request the first policy.
