UE Resource Capability Notification for MBMS Service Interest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of FeMBMS services, user equipment (UE) in receive only mode (ROM) session faces challenges with baseband resource capability management, leading to inefficient carrier aggregation configurations and excessive signaling traffic, which results in degraded performance and lack of prioritization control for user service experience.
Innovation Solution
A method and system for notifying the baseband resource capability of user equipment by determining events of interest or non-interest in MBMS services and transmitting corresponding ROM service interest indications to the serving cell, allowing for updated carrier aggregation configurations and reduced signaling traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE continuously reports service interest indications for MBMS services in ROM session, then the serving cell can maintain updated carrier aggregation configurations, but excessive signaling traffic is generated
Solution Approach 1:
The UE reports service interest indications periodically or event-triggered rather than continuously, reducing signaling traffic while maintaining configuration adaptability. The reporting is triggered by specific events such as service start/stop or interest changes.
Solution Approach 2:
The patent extracts and reports only the changed or relevant service interest information rather than continuously reporting the complete service interest status, reducing signaling overhead while maintaining configuration accuracy.
2Productivity
If the UE reports detailed baseband resource capability information, then the serving cell can optimize carrier aggregation configurations, but the device complexity and processing overhead increase
Solution Approach 1:
The patent reports baseband resource capability information selectively based on the specific service context and UE state, rather than continuously reporting all capability parameters. Only relevant capability information is reported when needed.
Solution Approach 2:
The UE pre-configures and stores baseband resource capability information, allowing the serving cell to retrieve and use this information for optimization without requiring real-time complex processing during service operations.
3Reliability
If the serving cell applies conservative carrier aggregation configurations to accommodate varying UE resource capabilities, then service reliability is maintained, but system throughput and performance are degraded
Solution Approach 1:
The carrier aggregation configuration is made dynamic and adaptive based on real-time UE service interest and baseband resource capability information. The configuration adjusts automatically to match UE capabilities, achieving both reliability and high throughput.
Solution Approach 2:
The UE provides feedback about its service interest and resource capability status to the serving cell, enabling the cell to optimize carrier aggregation configurations appropriately. This feedback mechanism allows the system to achieve high throughput while maintaining reliability through informed configuration decisions.

AI summary
The present disclosure describes method and system for notifying resource capability of user equipment. In accordance with the embodiments, the method includes determining an event related to one or more multimedia multicast-broadcast service (MBMS) service of interest to the UE in receive only mode (ROM) session when a system information related to MBMS is not broadcasted by a serving cell after transmission of an interest indication for MBMS service to the serving cell wherein the event indicates one of: (a) the UE is not interested in the one or more MBMS service through the ROM session; and (b) the UE is not in reception of the one or more MBMS service through the ROM session; and transmitting a ROM service interest indication for the one or more MBMS service through the ROM session corresponding to the determined event to the serving cell.
