Dynamic MBS Zone Configuration for Wireless Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, existing multicast and broadcast services (MBS) suffer from resource wastage and signal quality issues due to fixed broadcast zones, leading to inefficient use of radio resources and service disruptions when users move between zones.
Innovation Solution
A dynamic MBS zone configuration method that calculates signal quality values from multiple base stations and selectively changes base stations participating in the MBS zone based on terminal movement or elapsed time, optimizing resource allocation and ensuring seamless service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations are fixed in an MBS zone, then service coverage is stable, but radio resources are wasted when no terminals are present
Solution Approach 1:
The patent implements dynamic MBS zone configuration where base stations can be added or removed from the MBS zone based on terminal presence and signal quality. The serving base station receives terminal movement information and adjusts the MBS zone composition dynamically, allowing the system to adapt between static coverage stability and dynamic resource efficiency.
Solution Approach 2:
The patent changes the parameter of base station participation in the MBS zone based on signal quality metrics and terminal location. By evaluating signal quality values and terminal movement status, the system modifies which base stations participate in the MBS zone, thereby adjusting resource allocation to match actual service needs.
2Device complexity
If base stations are fixed in an MBS zone, then zone configuration is simple, but signal quality becomes non-uniform at zone edges
Solution Approach 1:
The patent applies local quality by evaluating signal quality specifically at different locations within the MBS zone, particularly at edge regions. The system identifies base stations that provide good signal quality to specific areas and adjusts zone configuration to ensure uniform service quality across the entire zone, rather than applying a uniform configuration approach.
Solution Approach 2:
The patent implements feedback mechanisms where terminal movement information and signal quality measurements are continuously monitored. The serving base station uses this feedback to dynamically adjust the MBS zone configuration, adding or removing base stations based on actual service quality requirements, thereby maintaining uniform signal quality throughout the zone.
3Ease of operation
If base stations are fixed in an MBS zone, then resource allocation is straightforward, but service disruption occurs when users move between zones
Solution Approach 1:
The patent implements preliminary action by proactively adjusting the MBS zone configuration in response to terminal movement information before service disruption occurs. The serving base station receives movement information and preemptively adds or removes base stations from the MBS zone to maintain continuous service coverage, rather than reacting after disruption occurs.
Solution Approach 2:
The patent makes the MBS zone configuration dynamic by allowing automatic addition and removal of base stations based on terminal movement and signal quality. This dynamic adjustment ensures service continuity as users move between areas, eliminating the service disruption problems associated with fixed zone configurations.
