MBMS Notification Message Subframe Selection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no established mechanism for transmitting MBMS notification messages from the network to user equipment, leading to inefficiencies in resource utilization and power consumption.
Innovation Solution
A method and system for transmitting MBMS notification messages using subframe configuration information and selection rules, where the network side determines the subframe for sending the message and instructs the user equipment to receive it using Radio Resource Control signaling, employing default, fixed, or dynamic subframe selection rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment continuously monitors MCCH information to ensure it receives all MBMS service updates, then information completeness is improved, but power consumption and resource usage increase significantly
Solution Approach 1:
The patent extracts the notification function from the MCCH information block, creating a separate MBMS notification message that indicates only when MCCH information changes. User equipment monitors this small notification message instead of the entire MCCH information, thereby reducing power consumption while ensuring information completeness is maintained through selective monitoring.
Solution Approach 2:
The MBMS notification message acts as an intermediary between the network and user equipment. Instead of user equipment directly monitoring all MCCH information, the notification message mediates by indicating whether changes occur, allowing equipment to selectively access MCCH only when necessary, thus balancing reliability and energy efficiency.
2Reliability
If user equipment monitors all MCCH information to ensure no service updates are missed, then service update completeness is improved, but network resource utilization deteriorates
Solution Approach 1:
The patent extracts the notification function from the MCCH information block, creating a separate MBMS notification message that indicates only when MCCH information changes. User equipment monitors this small notification message instead of the entire MCCH information, thereby reducing power consumption while ensuring information completeness is maintained through selective monitoring.
Solution Approach 2:
Instead of requiring user equipment to monitor all MCCH information (excessive action), the patent implements partial monitoring where equipment only monitors the concise notification message. This partial action is sufficient to determine whether full MCCH information needs to be received, optimizing network resource utilization while maintaining service update completeness.
3Productivity
If MBMS notification message transmission mechanism is established, then system efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal notification mechanism that can be applied across different MBMS service types and configurations. The subframe selection rules and notification message structure are designed to work generically for various scenarios, improving system efficiency without requiring complex service-specific implementations for each case.
Solution Approach 2:
The patent establishes preliminary configurations including default subframe selection rules and notification message formats before actual MBMS operations begin. By pre-defining these parameters and structures, the system achieves high efficiency during operation without requiring complex real-time decision-making, thereby reducing operational complexity while maintaining high productivity.
