MBS Interest Collection for Base Station Transmission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems face challenges in providing enhanced multicast and broadcast services, particularly in efficiently managing MBS interest information and optimizing MBS transmission across base stations to ensure efficient resource allocation and service delivery.
Innovation Solution
A communication control method that involves collecting MBS interest information from multiple base stations within a predetermined range and using this information to control MBS transmission, allowing for dynamic adjustment between PTM and PTP methods based on user equipment interest, enabling efficient resource allocation and service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If MBS transmission is provided to all user equipment in a coverage area, then service coverage is improved, but resource waste increases due to transmitting to user equipment not interested in the service
Solution Approach 1:
The base station collects MBS interest information from user equipment in advance before initiating MBS transmission. This preliminary collection of interest information allows the base station to determine which user equipment should receive the service, thereby avoiding resource waste from transmitting to uninterested devices while maintaining coverage area
Solution Approach 2:
The patent implements dynamic switching between PTM and PTP transmission modes based on the number of interested user equipment. When multiple devices are interested, PTM is used for efficient multicast; when fewer devices are interested, PTP is used for targeted unicast. This dynamic adaptation optimizes resource allocation while maintaining service coverage
2Adaptability or versatility
If MBS interest information is collected from all base stations in the network, then service coordination is improved, but system complexity increases
Solution Approach 1:
The patent limits MBS interest information collection to only those base stations within a predetermined range of the serving base station. This localized collection approach maintains service coordination capability while significantly reducing system complexity compared to collecting information from all base stations in the network
3Reliability
If user equipment in RRC idle or inactive state transitions to RRC connected state to notify MBS interest, then notification reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent allows user equipment in RRC idle or inactive state to notify MBS interest information through the random access procedure without completing the full transition to RRC connected state. This partial action approach maintains notification reliability while reducing signaling overhead by avoiding unnecessary connection establishment

AI summary
A communication control method used in a mobile communication system for providing a multicast and broadcast service (MBS) from a first base station to a first user equipment includes collecting, by the first base station and from at least one second base station within a predetermined range from the first base station, MBS interest information received by the at least one second base station from a second user equipment, and controlling, by the first base station, MBS transmission of the first base station, based on the MBS interest information collected.
