Shared RAN Broadcast Service Using Primary TMGI Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with shared radio access networks (RAN) among multiple operators, the same broadcast data is transmitted multiple times, leading to resource wastage due to overlapping broadcasts.
Innovation Solution
A method and device that assign a primary temporary mobile group identity (TMGI) for broadcast services, determining which operator's data to prioritize for transmission, thereby reducing overlapping broadcasts and optimizing resource usage.

If multiple operators transmit broadcast data through shared RAN, then broadcast service coverage is expanded, but resource wastage increases due to overlapping broadcasts
Solution Approach 1:
Multiple operators merge their broadcast data transmission through a shared RAN by selecting a primary TMGI from a list of TMGIs, combining multiple broadcast streams into a single transmitted signal to eliminate overlapping broadcasts and reduce resource wastage
Solution Approach 2:
The base station performs multiple functions by receiving broadcast data from multiple operators and selectively transmitting it based on the primary TMGI selection, enabling a single RAN node to serve multiple operators without redundant transmissions
2Productivity
If a primary TMGI is selected for broadcast service, then resource usage is optimized, but service continuity may be affected if TMGI changes
Solution Approach 1:
The network performs preliminary action by pre-configuring multiple TMGIs and establishing backup mechanisms before actual broadcast transmission, ensuring that if the primary TMGI changes, service continuity is maintained through pre-prepared alternative TMGIs
Solution Approach 2:
The system implements feedback mechanisms where the network monitors broadcast transmission status and TMGI validity, allowing dynamic switching to backup TMGIs if the primary TMGI becomes invalid or changes, thus maintaining service continuity while optimizing resource usage
