Stored Cell System Information for Low-Broadcast Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in energy consumption due to frequent broadcasting of system information, particularly in scenarios where there are no new devices accessing the network, leading to unnecessary resource usage.
Innovation Solution
Implementing a mechanism where communication devices and networks can store system information during active access and switch to a mode where broadcasting is paused, allowing devices to access cells using stored information, indicated by dedicated control messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system information is frequently broadcast to ensure device access, then device access capability is improved, but energy consumption and resource usage increase
Solution Approach 1:
The network stores system information in advance and provides it to devices via dedicated control messages before the device needs to access the cell. This preliminary provision of information eliminates the need for continuous broadcasting while ensuring devices have the necessary access information when needed.
Solution Approach 2:
The patent extracts system information from the continuous broadcast channel and delivers it through dedicated control messages only when necessary. This separation allows the network to reduce broadcasting activity while maintaining device access capability through targeted information delivery.
2Adaptability or versatility
If system information is broadcast to all devices, then all devices can access the cell, but resources are wasted when no new devices need access
Solution Approach 1:
The network monitors device presence and access needs, then adjusts system information delivery accordingly. When no new devices are present, the network stops broadcasting and uses stored information. When devices need access, the network activates broadcasting or provides information via dedicated messages. This feedback-driven adaptation optimizes resource usage.
Solution Approach 2:
The system dynamically switches between different operation modes: a low-activity mode where system information is stored and provided via dedicated messages, and a high-activity mode where broadcasting is enabled. This dynamic adaptation allows the network to optimize between resource savings and access capability based on real-time conditions.
3Loss of energy
If the network stops broadcasting system information to save energy, then energy consumption decreases, but devices cannot access the cell without stored information
Solution Approach 1:
The network performs preliminary storage of system information and provides it to devices before they need to access the cell. This advance preparation ensures that when broadcasting is stopped to save energy, devices still have the necessary information to access the cell reliably.
Solution Approach 2:
Dedicated control messages serve as an intermediary mechanism that bridges the gap between energy-saving broadcasting cessation and device access requirements. These messages carry system information from the network to devices, enabling access without continuous broadcasting.
Data Source
AI summary
Apparatuses and methods are provided for enabling a communication device in a cell of a network access the cell based on system information received from the network. The communication device receives a dedicated control message for releasing the communication device from a cell, the message comprising system information for storage in a memory of the communication device for use in access to the cell when network provided system information is unavailable in the cell, the dedicated control message indicating that system information is not transmitted in the cell. The device stores the system information received in the dedicated control message in the memory and then performs operations for access to the cell based on the stored system information.
