Core Network UAV Identification via SPID Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular networks face challenges in identifying Unmanned Aerial Vehicles (UAVs) and providing dedicated services, as existing methods lack efficient mechanisms to differentiate UAVs from other terminals and optimize radio resource management.
Innovation Solution
The method involves configuring a specific Subscriber Profile ID (SPID) value to indicate UAV identity in signaling, allowing the core network to differentiate UAVs and provide dedicated services, while omitting this SPID in other cases to offer common LTE services, thereby reducing signaling overhead and improving service efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specific SPID value is added to signaling to indicate UAV identity, then the base station can accurately identify UAVs and provide dedicated services, but the signaling overhead increases
Solution Approach 1:
The core network device determines whether the terminal is a UAV before generating signaling, and pre-configures the appropriate SPID value (first SPID for UAVs, second SPID for non-UAVs). This preliminary determination and configuration avoid the need to add UAV identification information to every signaling message, thus reducing overall signaling overhead while maintaining accurate UAV identification.
Solution Approach 2:
The patent applies different SPID values to different types of terminals: the first SPID value is specifically assigned to UAVs to enable dedicated service provisioning, while the second SPID value is assigned to non-UAV terminals for common LTE services. This local differentiation allows the network to optimize resource allocation and signaling for each terminal type without unnecessarily increasing overhead for all terminals.
2Adaptability or versatility
If the core network device determines terminal type and configures different SPID values, then dedicated UAV services can be provided, but the network device complexity increases
Solution Approach 1:
The terminal device includes information indicating its identity as a UAV or non-UAV in the access request message sent to the base station. The base station forwards this information to the core network device, which uses it to automatically determine the terminal type and select the appropriate SPID value. This self-service approach allows the terminal to provide its own identification information, reducing the burden on the core network device and simplifying its complexity while maintaining service differentiation capability.

AI summary
The present disclosure provides a UAV indication method and apparatus, the method is applied to a core network device and includes: receiving an access request from a terminal; adding a first SPID value to first signaling in response to determining that the terminal is a UAV according to the access request, where the first SPID value characterizes a UAV identity of the terminal; and transmitting the first signaling to a base station, such that the base station determines that the terminal is the UAV according to the first SPID value included in the first signaling and provides the terminal with a dedicated UAV service. Thus, the core network device informs the base station whether the terminal is a UAV through the first signaling, thereby saving signaling overheads and improving efficiency of providing the UAV service.
