Representative MCCH Indicator for MBMS-MDT Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) for multiple multicast-broadcast single-frequency network (MBSFN) areas in wireless communication systems is inefficient due to the lack of a standardized method for managing representative multicast control channels (MCCH) across multiple MBSFN areas.
Innovation Solution
Defining a representative MCCH indicator to efficiently configure MBMS-MDT, allowing user equipment (UE) to receive MBMS-MDT configuration via a single MCCH, which includes logging duration, interval, and area identity, thereby simplifying the configuration process across multiple MBSFN areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MBMS-MDT configuration is provided for multiple MBSFN areas separately, then each area can be configured independently, but the device complexity and configuration overhead increase significantly
Solution Approach 1:
The patent segments the MBMS-MDT configuration by introducing a representative MCCH indicator that identifies a specific MCCH among multiple MCCHs. This allows the configuration to be divided into: (1) a common part indicating which MCCH is representative, and (2) area-specific parts that can be independently configured. This segmentation resolves the contradiction by enabling independent configuration where needed while using the representative indicator to avoid redundant configuration overhead.
Solution Approach 2:
The representative MCCH indicator acts as an intermediary element that mediates between the multiple MCCHs and the MBMS-MDT configuration. Instead of directly configuring each MCCH independently (which increases complexity), the indicator serves as a reference point that simplifies the configuration process while still allowing independent control of each area's specific parameters.
2Adaptability or versatility
If a standardized method for managing representative MCCH is not defined, then flexibility in implementation is maintained, but configuration efficiency and resource management deteriorate
Solution Approach 1:
The patent creates a universal solution by defining a standardized representative MCCH indicator that can be applied across all MBSFN areas. This single indicator mechanism serves multiple functions: it identifies the representative MCCH, enables efficient configuration distribution, and facilitates resource management. This universal approach resolves the contradiction by providing a standardized method that improves productivity while maintaining implementation flexibility through configurable indicator values.
Solution Approach 2:
The invention introduces a new parameter (representative MCCH indicator) that changes the state of the system from unstandardized to standardized configuration management. By adding this parameter, the system achieves better configuration efficiency and resource management without sacrificing implementation flexibility, as the parameter can be configured to suit different deployment scenarios.

AI summary
A method and apparatus for configuring multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. A user equipment (UE) receives a representative multicast control channel (MCCH) indicator from a network, and receives a MBMS-MDT configuration on a representative MCCH, which is indicated by the representative MCCH indicator, among multiple MCCHs from the network. Thereafter, the UE performs MBMS-MDT based on the received MBMS-MDT configuration.
