Multimedia Broadcast Service Control via Location-Based Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the MBSFN-based MBMS service, mobile terminals waste battery power attempting to receive high MCS level services while far from the base station, as they are not capable of receiving such services, leading to inefficient resource utilization.
Innovation Solution
A multimedia broadcast and multicast service controlling apparatus and method that updates a service list based on user location, registers requested services in a pending list when not currently receivable, and provides the service when the terminal reaches a location capable of receiving it, using a receiving unit, list updating unit, pending list registration unit, and service providing unit to manage multicast control channel information and physical multicast channel settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal attempts to receive high MCS level services while far from the base station, then the service quality is improved, but battery power consumption increases unnecessarily
Solution Approach 1:
The system performs preliminary determination of service providability based on user location and MCS level before initiating service reception. The mobile terminal checks whether it is currently capable of receiving the requested service by evaluating its location relative to the base station and the required MCS level. Only if the service is determined to be providable does the terminal actually attempt to receive it, preventing unnecessary power consumption from attempting to receive services that cannot be received.
2Reliability
If the mobile terminal continuously monitors service availability, then service reception reliability is improved, but power consumption increases
Solution Approach 1:
The system implements periodic determination of service providability rather than continuous monitoring. The mobile terminal determines whether a service is currently providable at specific intervals or when location changes occur, rather than continuously monitoring service availability. This periodic approach maintains service reception reliability by ensuring the terminal only attempts to receive services when capable, while significantly reducing power consumption compared to continuous monitoring.

AI summary
Provided is a multimedia broadcast and multicast service controlling apparatus and method based on a user location. The multimedia broadcast and multicast service controlling apparatus may receive MCCH information, may periodically update a service list of a mobile terminal based on the received MCCH information, the service list listing services that are providable, may register a service in a pending list when the service is not included in the updated service list and is requested to be provided, and may provide the service registered in the pending list when the mobile terminal reaches a location where the mobile terminal may provide the service registered in the pending list.
