Mobile Communication Resource Allocation Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems experience undesired MAP overhead due to the need for periodic and fixed bandwidth allocation for VoIP services, which leads to inefficient resource allocation and increased signaling overhead.
Innovation Solution
A method for resource allocation in a mobile communication system that separates dynamic and fixed allocation slots within a radio resource region, allowing for efficient configuration and transmission of resource allocation information, including opposite direction allocation for fixed bandwidth services and dynamic allocation, and utilizing toggle patterns to reduce MAP overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic and fixed bandwidth allocation is used for VoIP services in conventional mobile communication systems, then service quality is maintained, but MAP overhead increases undesirably
Solution Approach 1:
The patent segments resource allocation into two distinct types: fixed allocation for periodic services (VoIP) and dynamic allocation for other services. This segmentation allows fixed allocation information to be broadcast separately and not included in periodic MAP messages, thereby reducing MAP overhead while maintaining service quality through dedicated fixed resource allocation.
Solution Approach 2:
The patent performs preliminary action by broadcasting fixed allocation information in advance before periodic service transmissions begin. This allows mobile stations to know their allocated resources beforehand, eliminating the need to include fixed allocation details in subsequent MAP messages, thus reducing overhead while ensuring service reliability.
2Loss of information
If fixed allocation information is included in every MAP message, then resource allocation is clear, but signaling overhead increases
Solution Approach 1:
The patent extracts fixed allocation information from periodic MAP messages and handles it separately through initial broadcast. This extraction removes redundant information from ongoing MAP transmissions, maintaining resource allocation clarity for mobile stations while significantly reducing signaling overhead in periodic communications.
Solution Approach 2:
The patent applies periodic action by broadcasting fixed allocation information only when changes occur, rather than including it in every periodic MAP message. This approach maintains resource allocation clarity while reducing the quantity of signaling data transmitted periodically, thereby lowering overhead.
3Productivity
If dynamic resource allocation is performed for each frame, then resource utilization efficiency is improved, but MAP overhead increases for services requiring fixed bandwidth
Solution Approach 1:
The patent segments resource allocation strategies by service type, applying dynamic allocation to services needing flexibility and fixed allocation to services requiring periodic bandwidth (like VoIP). This segmentation maintains high resource utilization efficiency for dynamic services while preventing MAP overhead increase for fixed-bandwidth services, as their allocation is broadcast separately and not included in periodic MAP messages.

AI summary
When characters are allocated to a keyboard, a plurality of consonants are divided into a plurality of groups according to pronunciation position in the oral cavity, and the groups are allocated to corresponding columns on the keyboard of 3 rows and 10 columns. A plurality of vowels are allocated to the corresponding columns according to the pronunciation position in the oral cavity. In this instance, the consonants and the vowels of which the pronunciation position are near the lips are allocated to the middle area of the area of 3 rows and 10 columns, and the consonants and the vowels of which the pronunciation position are near the vocal chords are allocated to the outer part of the area of 3 rows and 10 columns. The consonants and the vowels are allocated to the corresponding rows of the area of 3 rows and 10 columns according to usage frequency.
