Height-Based URSP Routing for 5G UE Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal/user equipment (UE) policies, such as URSP rules, do not adequately support specific service requirements, particularly for UEs operating at specific heights, leading to inadequate route selection.
Innovation Solution
Incorporating height information into the URSP rules, specifically through route selection descriptors (RSDs), to enable precise data transmission based on the height of the terminal, ensuring valid execution of RSDs only when the terminal is at the specified height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional URSP rules are used without height information, then the system maintains simplicity and broad compatibility, but it cannot support specific service demands related to terminal height
Solution Approach 1:
The patent embeds height information within the existing RSD structure as a nested parameter. The height information is incorporated into the route selection descriptor without disrupting the overall URSP rule architecture, allowing the system to maintain its original simplicity while adding specialized height-based routing capabilities for specific service demands.
Solution Approach 2:
The patent applies local quality by adding height information specifically to RSDs that require it, rather than modifying all URSP rules uniformly. This allows the system to maintain simplicity for general cases while providing enhanced adaptability for specific services that require height-based route selection, such as aerial vehicles or elevated installations.
2Measurement precision
If height information is added to RSD to enable height-based route selection, then route selection precision is improved, but the complexity of policy generation and management increases
Solution Approach 1:
The patent implements preliminary action by having the network element pre-generate multiple RSDs with different height information before data transmission begins. These pre-configured RSDs are stored and automatically selected based on the terminal's actual height, eliminating the need for complex real-time calculations and reducing the burden on policy generation during active transmission.
Solution Approach 2:
The patent introduces an intermediary network element that acts as a mediator between the terminal and the core network. This intermediary handles the complexity of height-based policy generation and management, translating terminal height information into appropriate RSD selections, thereby shielding the core network from direct complexity while maintaining precise route selection.
3Productivity
If generic URSP rules are used without height consideration, then the system operates with lower complexity, but data transmission efficiency for height-specific applications is insufficient
Solution Approach 1:
The patent applies dynamics by making the RSD selection adaptive to the terminal's height conditions. Instead of using static, generic URSP rules, the system dynamically selects appropriate RSDs based on real-time height information, enabling data transmission efficiency to be optimized for different operational scenarios such as ground-based, aerial, or elevated terminal positions.

AI summary
Provided are a method, apparatus, a non-transitory computer-readable storage medium for data transmission in a 5G communication system. The process may include generating a user equipment (UE) route selection policy (URSP), the URSP comprising a URSP rule, the URSP rule comprising a route selection descriptor (RSD), the RSD comprising height information, and the height information being used for indicating selection of the RSD to transmit application data based on a height of a terminal matching the height information. The process may also include transmitting the URSP to the terminal via a second network element.
