Radio Base Station Message Distribution Area Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional message distribution systems face increased processing load and delays when designating distribution areas across both sector and broader units, as they cannot coexist, leading to inefficiencies in warning message distribution.
Innovation Solution
A message distribution method and system that allows flexible designation of distribution areas by determining distribution area information and type at the message distribution station, which is then used by the radio base station to manage and distribute messages efficiently across various units, including maintaining a table associating distribution types with corresponding areas for preferential processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conventional message distribution system processes multiple pieces of distribution area information (both sector-level and broader-area level) simultaneously, then the distribution area coverage is improved, but the processing load on the radio base station increases and message distribution delay occurs
Solution Approach 1:
The distribution area information is segmented into two distinct types: sector-level distribution area information and broader-area distribution area information. Each type is processed independently through separate determination paths in the radio base station, avoiding the complexity of handling multiple overlapping area designations simultaneously while maintaining comprehensive coverage capability.
2Adaptability or versatility
If the radio base station processes many pieces of distribution area information for broader-area coverage, then the distribution area coverage is improved, but the message distribution speed decreases
Solution Approach 1:
The radio base station performs preliminary determination of the distribution type (sector-level or broader-area) before processing the actual message distribution. This preliminary classification allows the system to prepare appropriate processing paths in advance, enabling faster message distribution by avoiding complex real-time decisions about area coverage scope.
3Device complexity
If the conventional system uses a single type of distribution area information, then the system complexity is reduced, but the flexibility in designating distribution area units is limited
Solution Approach 1:
The system dynamically adapts its processing behavior based on the distribution type indicated in the distribution area information. When sector-level information is received, the radio base station follows one processing path; when broader-area information is received, it follows a different path. This dynamic adaptation provides flexibility in designating distribution area units while maintaining manageable system complexity through context-dependent processing.

AI summary
A message distribution method according to the present invention includes the steps of: (A) determining, at a message distribution station (CBC), distribution area information and a distribution type, based on a message distribution request received from a flash report transmission station (CBE) and containing distribution target area information, and reporting, from the message distribution station (CBC) to a radio base station (eNB), the distribution area information and the distribution; and (B) determining, at the radio base station (eNB), the distribution area, based on the distribution area information and the distribution type, and distributing, from the radio base station to the mobile station in the distribution area, a predetermined message.
