Keepalive Signaling Optimization via Preliminary State Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies face high signaling loads due to frequent transmission of keepalive information, which requires frequent radio resource control connection setups, leading to inefficient data exchange.
Innovation Solution
A method and system where a terminal transmits first information to a network device to instruct it to determine and optimize keepalive information, allowing for reduced signaling loads by optimizing the transmission process, such as entering specific states like CELL_FACH or CELL_PCH, and adjusting the frequency of keepalive information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If keepalive information is transmitted frequently to maintain connection, then connection reliability is improved, but signaling load increases
Solution Approach 1:
The terminal sends first information (indication message) to the network device in advance to notify that keepalive information will be transmitted. This allows the network device to prepare and optimize the transmission process beforehand, enabling it to enter specific states (CELL_FACH or CELL_PCH) and adjust transmission frequency, thereby reducing the signaling load caused by frequent keepalive transmissions while maintaining connection reliability
2Stability of the object's composition
If radio resource control connection setup is initiated frequently for keepalive transmission, then connection stability is improved, but transmission time increases
Solution Approach 1:
The network device receives the indication message in advance and enters specific states (CELL_FACH or CELL_PCH) before the actual keepalive information transmission. This preliminary state preparation avoids the need for frequent RRC connection setup processes, reducing the time required for each transmission while maintaining connection stability
Solution Approach 2:
The network device dynamically adjusts its state based on the received indication message, transitioning between different operational states (CELL_FACH, CELL_PCH, or CELL_DCH) to optimize the transmission process. This dynamic state adjustment allows the system to balance connection stability with transmission efficiency, reducing the time overhead of frequent setup processes
