MOB_NBR-ADV Message Flex Configuration for Bandwidth Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional MOB_NBR-ADV message in broadband wireless access communication systems is large in size due to unnecessary information, leading to significant bandwidth consumption and wastage of radio channel resources, as it broadcasts all information to all mobile stations regardless of their requirements.
Innovation Solution
A new field, NBR_FLAG, is introduced to indicate the presence or absence of specific information fields in the MOB_NBR-ADV message, allowing the serving base station to determine which fields to include, thereby reducing the message size and optimizing the use of radio channel resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the MOB_NBR-ADV message includes all neighbor base station information fields, then mobile stations can obtain complete neighbor information for handover, but the message size becomes large causing significant bandwidth consumption and radio channel resource wastage
Solution Approach 1:
The patent extracts only the necessary neighbor base station information fields that are currently required by mobile stations, removing unnecessary fields from the MOB_NBR-ADV message. This reduces message size and bandwidth consumption while maintaining handover capability, directly resolving the contradiction between complete information provision and resource efficiency
Solution Approach 2:
The patent introduces a dynamic field length configuration mechanism where the MOB_NBR-ADV message can be flexibly adjusted to include only the neighbor information fields that are currently needed. This dynamic adaptation allows the system to optimize bandwidth usage based on actual requirements while ensuring handover functionality is maintained
2Adaptability or versatility
If the MOB_NBR-ADV message includes all information fields, then all mobile stations receive comprehensive neighbor base station data, but radio channel resources are wasted transmitting unnecessary information
Solution Approach 1:
The patent extracts and transmits only the essential neighbor base station information fields that mobile stations currently require, eliminating redundant information from the MOB_NBR-ADV message. This reduces the quantity of transmitted data while maintaining adaptability for handover operations
Solution Approach 2:
The patent changes the parameter of message field inclusion by introducing flexible field length configuration, allowing the MOB_NBR-ADV message to include only necessary information fields. This parameter adjustment optimizes radio channel resource usage while preserving the adaptability needed for mobile station handover
