Core Network Paging Coordination for Inactive Terminal RNA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications systems, terminals in an inactive state may fail to be paged successfully when they move out of the configured radio access network notification area (RNA), leading to inefficiencies and resource wastage due to repeated paging attempts by network devices.
Innovation Solution
A communication method where a core network node receives RNA information from a first network device, identifies the relevant network devices for paging, and coordinates paging messages to prevent unnecessary overheads by selecting the appropriate network devices to page the terminal, ensuring successful paging even when the terminal moves out of the configured RNA.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the terminal moves out of the configured RNA without notifying the network device, then the terminal can maintain inactive state and save resources, but the network device cannot successfully page the terminal
Solution Approach 1:
The core network node pre-obtains RNA information including identification information of radio access network areas or tracking areas before paging is needed. This preliminary action enables the network to quickly determine which network devices should page the terminal without requiring the terminal to continuously report its location, thus saving terminal energy while maintaining paging reliability.
Solution Approach 2:
The core network node acts as an intermediary between the terminal and network devices. It receives RNA information from the first network device, processes this information to identify relevant network devices for paging, and coordinates the paging process. This intermediary role resolves the contradiction by enabling efficient paging coordination without requiring continuous terminal-n network device communication.
2Reliability
If network devices repeatedly page the terminal when it moves out of RNA, then the network can ensure paging coverage, but unnecessary paging overheads increase and network resources are wasted
Solution Approach 1:
The paging process is segmented and coordinated by the core network node based on RNA information. Instead of all network devices paging simultaneously, the core network node identifies specific network devices responsible for paging in different RNA areas. This segmentation reduces redundant paging attempts while maintaining comprehensive coverage, thus saving network resources.
Solution Approach 2:
The core network node performs partial paging by identifying and coordinating only the necessary network devices based on RNA information, rather than having all network devices attempt paging. This partial action approach achieves sufficient paging coverage while avoiding excessive paging overheads and resource waste.
