Selective Connection for Broadcast-Multicast Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the initial bandwidth part becomes congested when all broadcast-multicast services are provided within it, preventing wireless devices in idle or inactive states from receiving services outside this part due to lack of necessary information, leading to inefficient service distribution.
Innovation Solution
A method where wireless devices receive bandwidth information to determine if a connection to a broadcast-multicast service is required, allowing selective connection establishment within or outside the initial bandwidth part, enabling efficient service provision and reducing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all broadcast-multicast services are provided within the initial bandwidth part, then wireless devices in idle state can receive services, but the initial bandwidth part becomes excessively congested
Solution Approach 1:
The patent segments broadcast-multicast services into two categories: those provided within the initial bandwidth part (for idle/inactive devices) and those provided outside the initial bandwidth part (for connected devices). This segmentation allows services to be distributed across different bandwidth parts based on device state, reducing congestion on the initial bandwidth part while maintaining service accessibility.
2Quantity of substance
If broadcast-multicast services are provided outside the initial bandwidth part, then congestion is reduced, but wireless devices in idle state cannot receive services due to lack of necessary information
Solution Approach 1:
The patent applies local quality by providing different service delivery mechanisms tailored to specific device states. Devices in idle or inactive states receive broadcast-multicast services within the initial bandwidth part where they have access to necessary system information. Devices in connected states receive services outside the initial bandwidth part. This location-specific service distribution ensures each device state receives services through the most appropriate channel.
3Adaptability or versatility
If wireless devices establish connection to receive broadcast-multicast services outside initial bandwidth part, then service accessibility is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic service reception approach where the connection requirement adapts based on service location. When services are provided within the initial bandwidth part, devices in idle state can receive them without connection establishment. When services are provided outside the initial bandwidth part, devices establish connection to receive necessary information before accessing services. This dynamic adaptation optimizes the balance between service accessibility and device complexity.
