Wireless Connection Establishment Using Cell Identification and Paging Timers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in providing fast connection establishment and bearer setup, especially in heterogeneous networks with dual connectivity and wake-up radio capabilities, due to increased data traffic and the need for efficient resource management.
Innovation Solution
A method is proposed that involves transmitting minimum set indication (MSI) information and cell identification from terminals to networks, using timers for paging, and determining preferred user plane modes to efficiently establish connections between terminals and networks, including Non-3GPP RATs, to reduce connection time and enhance resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional connection establishment procedures are used in heterogeneous networks, then connection reliability is maintained, but connection establishment time increases
Solution Approach 1:
The terminal performs measurements and acquires information about Non-3GPP RATs before actual data transmission is required. The network entity stores measurement results, cell identification information, and user plane mode preferences in advance, so that when connection establishment is needed, the terminal can quickly select and connect to an available Non-3GPP RAT without performing full measurement procedures at that moment.
2Reliability
If comprehensive cell measurement and selection procedures are performed, then connection reliability is improved, but time consumption increases
Solution Approach 1:
Measurement and evaluation of Non-3GPP RATs are performed in advance by the terminal and stored by the network entity. The terminal reports measurement results, cell identification information, and user plane mode preferences before actual data transmission is required, so that when connection establishment is needed, the pre-acquired information can be directly used for rapid connection setup.
3Reliability
If the network performs paging across all tracking areas, then terminal reachability is ensured, but network resource consumption increases
Solution Approach 1:
The network entity uses stored cell identification information and user plane mode preferences to determine the most likely tracking area or cell where the terminal is located. Paging messages are targeted to specific tracking areas or cells based on this local information rather than broadcasting across all tracking areas, reducing unnecessary network resource consumption while maintaining terminal reachability.

AI summary
Disclosed herein is a method for establishing a connection between a terminal and a network entity in a wireless communication system including a Non-3GPP RAT. The method performed by a network entity comprises receiving, from the terminal, a first message including cell identification information indicating a last cell accessed by the terminal; running a first timer related to a paging when the network entity receives the first message; and transmitting a paging message to a cell corresponding to the cell identification information when the paging to the terminal is required before the running first timer expires.
