Dynamic MBMS Session Triggering for Cell-Based Broadcast Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Multimedia Broadcast Multicast Service (MBMS) technology limits network resource utilization efficiency due to statically planned multicast broadcast sessions, failing to adapt to changing terminal device locations.
Innovation Solution
A method where the core network device dynamically determines interested terminals and associated cells, sending information to access network devices to confirm MBMS reception needs, establishing broadcast connections only where necessary, thereby improving transmission flexibility and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static planning is used for MBMS session initiation, then network device configuration is simplified, but MBMS transmission flexibility is limited and network resource utilization efficiency is reduced
Solution Approach 1:
The patent implements dynamic MBMS session initiation by allowing access network devices to autonomously initiate session establishment based on real-time terminal distribution information. The core network device receives terminal location data, determines target access network devices dynamically, and establishes sessions adaptively rather than relying on static pre-configuration. This dynamic approach resolves the contradiction by making the system flexible while maintaining manageable complexity through automated decision-making algorithms.
2Device complexity
If static planning is used for MBMS session initiation, then network device configuration is simplified, but network resource utilization efficiency is reduced
Solution Approach 1:
The patent employs feedback mechanisms where the core network device receives terminal distribution information from access network devices, processes this feedback data to identify optimal target cells, and adjusts session initiation decisions accordingly. This closed-loop feedback system enables efficient network resource allocation by continuously adapting to changing terminal locations and service demands, thereby resolving the contradiction between configuration simplicity and resource utilization efficiency.
3Adaptability or versatility
If dynamic determination of target cells is implemented, then MBMS transmission flexibility is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary core network device that acts as a mediator between access network devices and terminal users. This intermediary processes terminal distribution information, determines optimal target access network devices and cells, and coordinates session establishment. By centralizing the complex decision-making logic in the core network device, the system achieves high transmission flexibility while managing complexity through a dedicated coordinating entity rather than distributing complexity across multiple access devices.

AI summary
The present application provides a multimedia broadcast multicast service transmission method, an apparatus, a device and storage medium, the method includes: a core network device determines a target terminal which is interested in a target MBMS; the core network device determines a cell associated with the target terminal; the core network device sends first information to an access network device to which the cell associated with the target terminal belongs, the first information is used to trigger the access network device to confirm whether the target MBMS needs to be received; establishes a broadcast connection with the access network device for the target MBMS, if second information from the access network device or the target terminal is received by the core network device, the second information is used to indicate the access network device needs to receive the target MBMS. The present application improves a flexibility of MBMS transmission and improves a utilization efficiency of network resources.
