SC-MCCH Resource Configuration via Change Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective resource configuration method applicable to the Single-Cell Multicast Control Channel (SC-MCCH) in existing MBMS technologies, which hinders efficient resource management and utilization.
Innovation Solution
A resource configuration method and system that involves a base station sending a system broadcast message containing configuration information for the SC-MCCH, including Modification Period (MP), time-domain location, and change notification information, using DCI in PDCCH or a value tag to indicate changes, allowing User Equipment (UE) to determine if SC-MCCH information has changed and update accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MCCH information is periodically sent to all UEs, then UEs can receive MBMS control information, but network resource consumption increases and power consumption of UEs increases
Solution Approach 1:
The patent extracts only the essential change notification information from the full MCCH information and sends it separately via MBMS notification messages. This allows UEs to selectively receive only change notifications rather than all MCCH information periodically, reducing power consumption while maintaining reliable detection of MCCH changes.
Solution Approach 2:
The patent sends MBMS notification messages in advance to indicate whether MCCH information will change. UEs can check these preliminary notifications before attempting to receive full MCCH information, avoiding unnecessary reception operations and reducing power consumption while ensuring reliable information delivery.
2Loss of information
If UEs monitor all MCCH information periodically, then UEs can detect MCCH changes, but resource consumption and power consumption increase
Solution Approach 1:
The patent extracts change notification indicators from the full MCCH information and transmits them separately via MBMS notification messages. UEs only need to monitor these compact notification messages to detect MCCH changes, rather than continuously receiving all MCCH information, significantly reducing power consumption while maintaining complete change detection capability.
Solution Approach 2:
The patent implements partial action by sending only the essential change notification portion of MCCH information through MBMS notification messages. UEs perform partial monitoring by checking only these notification messages rather than all MCCH content, reducing resource consumption while ensuring no change information is missed.
3Speed
If MBMS notification messages are sent frequently, then UEs can detect MCCH changes timely, but network resource consumption increases
Solution Approach 1:
The patent implements periodic sending of MBMS notification messages at optimized intervals rather than continuous transmission. This periodic action ensures UEs receive timely change notifications while avoiding excessive network resource consumption during periods when no MCCH changes occur, achieving a balance between notification speed and resource efficiency.

AI summary
A resource configuration method, system and device for a Single-Cell Multicast Control Channel (SC-MCCH) are provided. In the method, a base station sends a system broadcast message, which includes configuration information of the SC-MCCH configured by the base station, the configuration information includes a Modification Period (MP) of the SC-MCCH and time-domain location information of the SC-MCCH, and the configuration information further includes at least one of: a Repetition Period (RP) of the SC-MCCH, configuration information of SC-MCCH change notification information, and a value tag.
