Offloading Common Control Data to Broadcast Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face increased load due to the transmission of common control data across multiple cells, which can lead to network congestion and reduced capacity, as this data is typically sent through each cell individually.
Innovation Solution
A method is introduced to send common control data through a broadcast network instead of individual wireless network cells, utilizing a high tower high power broadcast network to cover the areas of multiple cells, thereby reducing the load on each cell and the overall network by broadcasting this data through a single, geographically wider broadcast cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common control data is transmitted through each individual cell in the wireless network, then each cell can independently provide control data to user equipment, but the aggregated load on the network increases and cell capacity is reduced
Solution Approach 1:
The patent merges the transmission of common control data from multiple individual cells into a single broadcast network transmission. The network controller identifies control data that is identical across multiple cells and routes it through the broadcast network instead of having each cell transmit it separately, thereby consolidating redundant transmissions and reducing overall network load.
Solution Approach 2:
The broadcast network acts as an intermediary between the network controller and user equipment for transmitting common control data. Instead of direct cell-to-UE transmissions for common control information, the broadcast network mediates the delivery, efficiently distributing identical control data to multiple cells' user equipment simultaneously.
2Ease of operation
If common control data is sent through multiple cells, then all user equipment in those cells receives the data, but the load on each cell and the overall network increases
Solution Approach 1:
The patent extracts common control data from the individual cell transmission paths and relocates it to the broadcast network for transmission. By separating the common control data transmission function from the individual cells and placing it in the broadcast network, the system eliminates redundant transmissions while maintaining complete data distribution to all affected user equipment.
3Productivity
If broadcast network is used to transmit common control data, then the load on wireless network cells is reduced, but the broadcast network must cover multiple cell areas
Solution Approach 1:
The broadcast network is utilized for a dual function: its traditional broadcast services and the additional function of transmitting common control data for multiple wireless network cells. This multi-functional use of the broadcast network infrastructure allows it to efficiently handle control data distribution across its broader coverage area without requiring dedicated resources for each individual cell.
