Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In 5G systems, there is a lack of efficient mechanisms for nodes to determine when to initiate or cancel location procedures, leading to unnecessary occupation of storage space and resources.

Innovation Solution

Implement a method where access management network elements receive information to release location resources based on specific messages, such as UL NAS TRANSPORT or cancel location messages, to manage resource allocation efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If location procedures are initiated without efficient cancellation mechanisms, then location services can be provided, but storage space and network resources are unnecessarily occupied

Engineering Contradiction:

Improvelocation service availabilityVSAvoidstorage space occupation

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements a feedback mechanism where the access management network element receives cancellation information from the location management network element about location request cancellations. This feedback enables the access management network element to release location resources timely, preventing unnecessary storage occupation while maintaining location service availability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent establishes a preliminary cancellation procedure where the location management network element notifies the access management network element about upcoming location request cancellations before the resources are fully consumed. This preliminary action allows the system to prepare for resource release, ensuring both service continuity and efficient resource management.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If location resources are held for extended periods, then location requests can be fulfilled, but network resource usage increases unnecessarily

Engineering Contradiction:

Improvelocation request fulfillmentVSAvoidnetwork resource consumption

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The cancellation information message serves as a feedback signal that triggers immediate resource release actions. This feedback loop ensures that location resources are held only for the duration necessary to fulfill location requests, preventing prolonged resource occupation and reducing network energy consumption.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent implements a mechanism where location resources are systematically discarded (released) when cancellation information is received, and these resources can then be recovered and reallocated for new location requests. This discarding and recovering process optimizes resource turnover and reduces cumulative network resource consumption.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

Embodiments of this application provide a location method and apparatus. The method includes: An access management network element receives first information in a cancel location procedure, where the first information indicates the access management network element to release a location resource for a location request. The access management network element releases the location resource based on the first information. In this way, in the cancel location procedure, the access management network element may release the location resource based on the first information, helping save storage space.
