Broadcast Session Sharing to Eliminate Redundant RAN Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a RAN sharing scenario where multiple PLMNs set up sessions for a same broadcast service, existing methods lead to redundant network resource usage and inefficiency due to the establishment of multiple transmission channels for each session, which is costly and inefficient.
Innovation Solution
A communication method where a network device determines that multiple sessions belong to the same broadcast service and sends indication information to other network devices to avoid setting up redundant transmission channels, such as F1-U and NG-U tunnels, thereby optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission channels are set up for each broadcast session in RAN sharing scenario, then each PLMN can independently manage its broadcast service, but network resources are wasted due to redundant channel establishment
Solution Approach 1:
The patent merges multiple transmission channels that carry the same broadcast service into a single shared channel. When multiple PLMNs request broadcast sessions for the same service, the system identifies the redundancy and consolidates the transmission resources, allowing one channel to serve multiple PLMNs simultaneously while reducing overall network resource consumption.
Solution Approach 2:
The patent makes a single transmission channel universal by enabling it to serve multiple PLMNs for the same broadcast service. The channel is configured to handle requests from different PLMNs without requiring separate dedicated channels, thus achieving multi-functionality and improving resource utilization efficiency.
2Reliability
If separate transmission channels are established for each broadcast session, then service quality can be guaranteed, but device complexity and operational costs increase
Solution Approach 1:
The patent combines multiple channel management functions into a unified management mechanism. By identifying that multiple channels serve the same broadcast service, the system merges their management into a single process, reducing the complexity of channel setup, monitoring, and maintenance while preserving service quality through centralized control.
3Reliability
If redundant transmission channels are set up for the same broadcast service, then service availability is improved, but network resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges redundant transmission channels into a single efficient channel configuration. By detecting that multiple channels are carrying identical broadcast service data, the system consolidates them into one channel that maintains service availability while eliminating duplicate resource consumption, thus improving overall resource utilization efficiency.
Solution Approach 2:
The patent converts the harmful effect of redundant channel establishment into a benefit by using the redundancy detection mechanism to identify optimization opportunities. The system leverages the presence of multiple channels to trigger consolidation actions, transforming what was previously a waste into a resource optimization opportunity that improves efficiency.

AI summary
A communication method and apparatus are provided. The method includes: A first network device receives a request message, where the request message is used to request to create a first broadcast session for a first PLMN, and the first broadcast session is a session of a first broadcast service. If the first network device determines, based on the request message, that the first broadcast session and a second broadcast session belong to sessions of the first broadcast service, and the second broadcast session is a session created for a second PLMN, the first network device sends first indication information to a second network device, where the first indication information indicates not to set up a first transmission channel for the first broadcast session, and the first transmission channel is a channel for transmitting the first broadcast service.
