Dynamic Bearer Channel Selection for Seamless Content Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face limitations in content broadcasting, including limited data transmission capacity of point-to-point bearer channels and restricted bandwidth of point-to-multipoint channels, leading to interrupted content reception and inefficient resource utilization when mobile terminals move between network coverage areas.
Innovation Solution
A device that dynamically selects the most suitable bearer channel type for content broadcasting by determining and communicating broadcast parameters, switching between point-to-point and point-to-multipoint channels based on availability and quality, and managing rerouting data to optimize content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If point-to-point bearer channels are used for content broadcasting, then content delivery flexibility is improved, but data transmission capacity is limited
Solution Approach 1:
The patent combines both point-to-point and point-to-multipoint bearer channel capabilities into a single communication system. The terminal equipment can selectively switch between unicast (point-to-point) and broadcast (point-to-multipoint) modes, merging the flexibility advantages of unicast with the high capacity advantages of broadcast to resolve the contradiction between delivery flexibility and data transmission capacity.
2Productivity
If point-to-multipoint bearer channels are used for content broadcasting, then bandwidth efficiency is improved, but reception reliability is reduced when terminals move between coverage areas
Solution Approach 1:
The patent implements dynamic bearer channel selection where the terminal equipment can adaptively switch between point-to-multipoint and point-to-point modes based on real-time reception conditions and mobility state. When reception quality degrades during movement, the system dynamically transitions from broadcast to unicast mode, maintaining reliability while preserving bandwidth efficiency during stable broadcast conditions.
3Reliability
If ESG data is updated frequently to reflect bearer channel availability, then content access reliability is improved, but network signaling overhead increases
Solution Approach 1:
The patent enables terminal equipment to autonomously determine bearer channel availability and select appropriate reception modes without requiring frequent ESG updates. The terminal self-ervices by monitoring its own reception conditions and making intelligent decisions about which bearer type to use, thereby maintaining content access reliability while minimizing network signaling overhead for ESG updates.

AI summary
A device (D1, D2) is dedicated to selection of a type of bearer channel for broadcasting contents between a service platform (PS) adapted to set up point-to-point and point-to-multipoint type bearer channels and a terminal (UE), each content being associated with at least one set of broadcast parameters defining at least the type of bearer channel for broadcasting it and the frequency channel on which it is broadcast on a bearer channel of said type. This device comprises: i) control means (MC1) adapted, in case of selection of a content by the user of a communication terminal (UE), to determine data representing at least one set of broadcast parameters associated with said selected content, and ii) selection means (MS1) adapted, in the presence of a set that has been determined designating an accessible point-to-multipoint bearer channel, to communicate to the terminal (UE) the broadcast parameters of that set so that it can receive the selected content on the designated point-to-multipoint type bearer channel, and if not, to request the creation by the service platform (PS) of a point-to-point type bearer channel with the terminal (UE) so that it can receive the selected content on the point-to-point type bearer channel that has been created.
