MBS State Indication Feedback for Efficient Multicast Data Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multicast and broadcast service systems face inefficiencies and resource wastage due to blind data transmission by the AF to the core network element, leading to invalid data transmission and poor user experience.
Innovation Solution
Implementing a communication method where the AF negotiates a transmission policy with core network elements to receive and transmit MBS service data matching MBS service status indication information, including information types, content, and frequency, to ensure efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the AF entity blindly transmits MBS service data to the core network element without checking network status, then the data transmission process is simple and fast, but the transmission efficiency deteriorates due to invalid data transmission
Solution Approach 1:
The AF entity performs preliminary actions by negotiating a transmission policy with the core network element before transmitting MBS service data. This policy includes obtaining MBS service status indication information that reflects network conditions, allowing the system to determine in advance whether transmission is appropriate, thereby avoiding wasted network resources and improving overall transmission efficiency
Solution Approach 2:
The system implements feedback mechanisms where the core network element provides MBS service status indication information to the AF entity. This feedback loop allows the AF entity to adjust its transmission behavior based on current network conditions, ensuring data is only transmitted when network status is suitable, thus resolving the contradiction between transmission simplicity and efficiency
2Productivity
If the AF entity negotiates transmission policy and checks MBS service status before transmitting data, then transmission efficiency improves, but the system complexity increases
Solution Approach 1:
The patent applies universality by using a standardized transmission policy framework that can be applied to different MBS service scenarios. The negotiation mechanism between AF entity and core network element establishes a universal protocol for status checking and policy determination, which can handle various network conditions and service types through a single unified approach, thereby managing complexity effectively
Solution Approach 2:
The system manages complexity through parameter changes by negotiating specific transmission policy parameters (such as transmission frequency, data volume, timing) based on network conditions. Rather than redesigning the entire system, the AF entity adjusts transmission parameters according to MBS service status indication information, allowing efficient adaptation to varying network states while maintaining a relatively simple base architecture

AI summary
Embodiments of the present application provide a communication method and apparatus for a multicast and broadcast service, a medium, and an electronic device. The communication method for a multicast and broadcast service comprises: an application function AF performs a communication negotiation of an MBS service with a core network element to determine a transmission policy of MBS service state indication information; on the basis of the transmission policy, the application function AF receives the MBS service state indication information sent by the core network element; the application function AF sends MBS service data matching the MBS service state indication information to the core network element according to the MBS service state indication information, so that the core network element transmits the MBS service data to a terminal device.
