MBS Zone Resource Allocation via Overlap Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in managing radio resources across overlapping Multicast and Broadcast Service (MBS) zones, leading to signal interference and inefficient resource utilization.
Innovation Solution
A method and system for identifying overlapping MBS zones, generating indices to determine overlap relationships, and assigning unique identifiers for resource allocation, ensuring that non-overlapping zones share resources while overlapping zones use distinct resources to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If MBS zones overlap to expand service coverage, then service area is improved, but signal interference increases
Solution Approach 1:
The patent segments the MBS zone management into multiple independent components: zone identification units at base stations, overlap detection mechanisms, and separate resource allocation processes. This segmentation allows the system to identify and manage overlapping zones without allowing interference to propagate system-wide, thus maintaining expanded coverage while preventing interference accumulation.
Solution Approach 2:
The patent introduces an intermediary resource allocation mechanism that mediates between overlapping MBS zones. This intermediary layer assigns distinct communication resources (time slots, frequency channels, codes) to overlapping zones, acting as a buffer that prevents direct interference while maintaining the benefits of zone overlap for extended coverage.
2Reliability
If distinct resources are assigned to overlapping zones to prevent interference, then signal quality is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where communication resources are assigned based on real-time detection of zone overlaps. When zones overlap, distinct resources are assigned to maintain signal quality; when zones do not overlap, resources can be shared or reallocated. This dynamic approach ensures signal quality in overlapping regions while maximizing resource utilization in non-overlapping regions.
Solution Approach 2:
The patent changes the parameter of resource assignment from static to conditional based on overlap detection. The system monitors zone relationships and adjusts resource allocation parameters dynamically - assigning distinct resources when overlaps are detected and allowing resource sharing when zones are separate, thus balancing signal quality and efficiency.
3Productivity
If resource allocation is optimized for non-overlapping zones, then resource efficiency is improved, but interference management capability deteriorates
Solution Approach 1:
The patent performs preliminary detection of zone overlaps before resource allocation occurs. By identifying overlapping zones in advance through zone identification units and overlap detection mechanisms, the system can pre-assign appropriate communication resources, ensuring both efficient allocation for non-overlapping zones and proper interference management for overlapping zones in a single coordinated process.

AI summary
A method for providing resource allocation in a communication network includes identifying at least two broadcast zones for receiving broadcast services in the communication network and generating a first index based on a relative relationship among the at least two broadcast zones. The first index includes information indicative of whether a first broadcast zone overlaps with at least one other broadcast zone. The method further includes generating a second index based on the relative relationship among the at least two broadcast zones; assigning at least one identifier to each of the at least two broadcast zones based on the first index and the second index; and enabling data transmissions to the at least two broadcast zones based on the assigned identifiers and using the at least one communication resource associated with the identifiers. The second index may include information indicative of a number of broadcast zones overlapped with the first broadcast zone. Each identifier may be associated with at least one communication resource, with distinct identifiers being assigned to overlapping broadcast zones of the at least two broadcast zones.
