Location Information Provisioning in IoT NTN Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in efficiently providing location information during Early Data Transmission (EDT) and Preconfigured Uplink Resources (PUR) procedures in IoT networks, particularly in Non-Terrestrial Networks (NTN), where coarse location information is often delivered in Msg5, which may not be sufficient for network mapping and core network selection.
Innovation Solution
The method involves configuring and delivering location information during EDT or PUR transmissions by allowing the UE to send location information using Preconfigured Uplink Resources (PURs) or as part of the connection establishment procedure, enabling the network to determine the UE's location for accurate core network selection, with options for sending coarse, fine, or no location information based on specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information is delivered in Msg5 during connection establishment, then the network can obtain UE location, but the location information may be coarse and insufficient for accurate core network selection in NTN scenarios
Solution Approach 1:
The patent applies preliminary action by delivering location information in Msg3 (RRCConnectionSetupComplete) before the connection establishment is fully completed. This allows the network to obtain location information earlier in the procedure, enabling timely core network selection and routing decisions without waiting for Msg5, thus resolving the contradiction between obtaining accurate location information and minimizing connection establishment delay.
2Device complexity
If location information is sent using PURs, then the network can obtain location information with reduced signaling overhead, but the procedure may not complete full connection establishment
Solution Approach 1:
The patent applies dynamics by making the location information delivery method flexible and conditional. The UE can send location information either in Msg3 during connection establishment or using PURs in idle mode, depending on network configuration, UE capabilities, and service requirements. This dynamic approach allows the system to optimize between signaling overhead and reliability based on specific operational contexts.
3Loss of time
If the UE sends location information in Msg3, then the network can determine UE location earlier, but the message size and processing complexity increase
Solution Approach 1:
The patent applies segmentation by separating location information into different delivery stages. The UE can send coarse location information in Msg3 for immediate network selection purposes, while finer location details can be provided later through PUR transmissions or during connected mode operations. This segmentation allows early location determination without overwhelming the initial message processing capacity.
4Productivity
If coarse location information is used for NTN mapping, then the network can perform basic routing, but accurate core network selection may not be achieved
Solution Approach 1:
The patent applies preliminary action by using coarse location information from Msg3 to enable immediate preliminary routing and network selection, while allowing for subsequent refinement of location accuracy through PUR transmissions. This ensures that the network can begin routing operations without delay while progressively improving selection accuracy as more precise location data becomes available.
Data Source
AI summary
A method (1700) performed by a UE for location provisioning. The method includes determining to send location information. The method also includes, as a result of determining to send location information, sending the location information to a network node. Sending the location information to the network node comprises sending the location information using one or more PURs or sending a connection establishment procedure message as part of a connection establishment procedure, wherein the connection establishment procedure message comprises the location information.
