Multicast Broadcast Service Handover With Service-Specific Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in ensuring seamless multicast broadcast service continuity during handovers in connected states, particularly in scenarios involving different types of services with varying requirements such as eMBB, URLLC, and mMTC, which can disrupt communication channels and affect reliability and latency.
Innovation Solution
A user equipment (UE) receives measurement configuration parameters for handover decisions associated with different types of services and transmits measurement reports, followed by a radio resource control (RRC) reconfiguration message to facilitate a smooth handover to a target cell, maintaining service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handover procedures are optimized for different service types (eMBB, URLLC, mMTC), then service-specific reliability and latency are improved, but device complexity and measurement configuration overhead increase
Solution Approach 1:
The patent segments the handover measurement configuration into service-specific configurations for different service types (eMBB, URLLC, mMTC). Each service type receives tailored measurement parameters, reporting criteria, and handover thresholds, allowing optimized handover procedures for each service while managing device complexity through structured organization of measurement configurations.
Solution Approach 2:
The patent implements dynamic measurement configuration that adapts to current service requirements and radio conditions. The network can dynamically adjust measurement parameters, reporting intervals, and handover thresholds based on active service types, enabling flexible optimization of service continuity while managing device resources efficiently.
2Reliability
If service-specific measurement configurations are implemented, then handover reliability for different services is improved, but signaling overhead and network complexity increase
Solution Approach 1:
The patent establishes a universal handover framework that handles multiple service types (eMBB, URLLC, mMTC) through a common measurement and reporting mechanism. The system uses unified RRC signaling procedures and measurement object structures that can accommodate different service requirements, reducing network complexity while maintaining service-specific optimization capabilities.
Solution Approach 2:
The patent changes key parameters such as measurement reporting intervals, thresholds, and criteria based on service type requirements. By dynamically adjusting these parameters rather than implementing completely separate measurement systems, the patent reduces signaling overhead and network complexity while still achieving service-specific handover optimization.

AI summary
A system, method and apparatus for mobile communications including is provided. A user equipment (UE) receives measurement configuration parameters including one or more first measurement configuration parameters for handover decisions associated with one or more first services, the one or more first services associated with a first type of service and one or more second measurement configuration parameters for handover decisions associated with one or more second services. The first services are associated with a first type of service and the second services are associated with a second type of service. The UE transmits one or more measurement reports that include the two types of measurement information. The UE then receives a radio resource control (RRC) reconfiguration message indicating a handover to the target cell and establishes a connection with the target cell based on the received the RRC reconfiguration message.
