Positioning Status Reporting for Wireless Network Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in LTE networks, there is a need for efficient reporting of positioning status by user equipment (UE) to optimize network performance, as existing methods lack the ability to dynamically adapt to changes in UE's positioning capabilities, leading to inefficient resource allocation and network optimization.
Innovation Solution
A method where the UE checks its positioning status and sends a positioning status report message to the network, which includes information on the availability of location information and any changes, allowing the network to reconfigure UE operations based on the reported status, using a prohibit timer to manage reporting frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network configures MDT for all UE, then coverage optimization can be performed, but resources are wasted on UE that cannot provide location information
Solution Approach 1:
The network performs preliminary checking of UE positioning capability before configuring MDT. The network receives positioning status information from UE indicating whether the UE can obtain location information, and only configures MDT for UE that are capable of providing location information, thereby avoiding resource waste on incapable UE
Solution Approach 2:
The network receives feedback from UE about their positioning status and capability to provide location information. Based on this feedback, the network dynamically adjusts MDT configuration decisions, configuring MDT only for UE that can actually provide location information for coverage optimization
2Productivity
If the network frequently checks UE positioning status, then resource allocation can be optimized, but signaling overhead increases
Solution Approach 1:
The UE performs preliminary self-checking of positioning status and proactively reports this status to the network before the network needs to allocate resources. This eliminates the need for frequent network-initiated checking and reduces signaling overhead
Solution Approach 2:
The UE autonomously determines its own positioning status and capability to provide location information, then reports this self-determined status to the network. This self-service approach reduces the need for network-side checking and minimizes signaling overhead
3Quantity of substance
If the network waits for UE to report positioning status changes, then signaling is reduced, but resource allocation responsiveness decreases
Solution Approach 1:
The UE proactively reports positioning status information to the network before the network needs to make resource allocation decisions. This preliminary reporting ensures the network has up-to-date information for responsive resource allocation without requiring frequent polling
Solution Approach 2:
The UE continuously monitors its positioning status and provides feedback to the network when status changes occur. This feedback mechanism ensures the network receives timely updates for responsive resource allocation while minimizing unnecessary signaling during stable periods

AI summary
Provided is a method for reporting positioning status by a terminal in a wireless communication system. The method comprises: confirming a positioning status related to whether location information of a terminal can be provided; and when the positioning status is confirmed, transmitting a positioning status reporting message via a network. The positioning status reporting message comprises positioning status information indicating the positioning status of the terminal.
