Sensing Service Paging in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently discovering and verifying User Equipment (UE) capable of participating in sensing operations, especially when UEs are in Idle or RRC-Inactive states.
Innovation Solution
The system implements a method where the Radio Access Network (RAN) initiates paging for UEs capable of participating in sensing services, and the UEs respond with a service request message indicating their eligibility and capabilities. This process includes configuration of UEs to monitor specific radio resources and verify their authorization to perform sensing tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network performs discovery procedures for UEs in Idle or RRC-Inactive states, then the ability to discover capable UEs is improved, but the network complexity and signaling overhead increase
Solution Approach 1:
The patent applies preliminary action by having UEs pre-configure sensing capabilities and authorization status before entering Idle or RRC-Inactive states. The network stores this pre-configured information during UE registration, enabling rapid discovery without complex real-time verification procedures when UEs need to be recruited for sensing tasks.
2Productivity
If the network initiates paging for sensing services, then the efficiency of discovering UEs is improved, but the signaling overhead and network resources consumed increase
Solution Approach 1:
The patent applies partial action by implementing selective paging that targets only UEs with specific sensing capabilities and authorization status. Rather than paging all UEs in Idle or RRC-Inactive states, the network filters and pages only those whose pre-configured attributes match the sensing task requirements, reducing unnecessary signaling overhead while maintaining discovery efficiency.
3Reliability
If UEs respond to paging messages with service request messages, then the verification of UE authorization is improved, but the time required for discovery procedures increases
Solution Approach 1:
The patent applies preliminary action by having UEs pre-verify and store their authorization status and sensing capabilities during initial network registration. This pre-configuration eliminates the need for time-consuming real-time authorization verification when UEs receive paging messages, allowing rapid response while maintaining reliable verification.

AI summary
Various aspects of the present disclosure relate to: receiving a paging message for a sensing service, wherein the paging message comprises sensing service information; determining whether to reply to the paging message based in part on whether the UE is configured to participate in the sensing service; and transmitting a service request message comprising an indication that the service request message is a response to the paging message for the sensing service.
