Virtual Cell Segmentation for Location-Specific Broadcasting Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-specific services in broadcasting systems face challenges in adapting their large service areas to meet specific and geographical requirements, leading to inflexible and inefficient service delivery.
Innovation Solution
The method involves setting up cells for location-specific services by transferring cell data from a broadcasting unit to a mobile receiving device, which determines its presence in the cell area and performs assigned services. This allows for dynamic and flexible service area segmentation into smaller, interactive cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a broadcasting system uses a large service area to reach many listeners with few transmitters, then economic efficiency is improved, but the system cannot be flexibly adapted to specific geographical requirements and location-specific services
Solution Approach 1:
The patent divides the large broadcasting service area into multiple smaller virtual cells defined by cell data (center coordinates, radius, service parameters). Each cell can be independently configured for location-specific services while the overall system maintains broad coverage. Mobile receiving devices receive and store cell data, determine their position, and identify which cell they are in to receive appropriate services.
Solution Approach 2:
The patent introduces a virtual dimension by overlaying a cell-based logical structure on top of the physical broadcasting coverage area. Cell data define virtual service regions that can be arbitrarily shaped and sized, allowing flexible adaptation to geographical requirements without adding physical transmitters. This virtual cell layer enables location-specific services while maintaining the economic efficiency of few physical transmitters.
2Measurement precision
If location-specific services are provided within a small area, then service precision is improved, but the broadcasting system requires complex back channels and communication infrastructure
Solution Approach 1:
The patent performs preliminary action by having mobile receiving devices receive and store cell data in advance. The devices determine their position and identify which cell they are in without requiring real-time back channel communication. Service identification and delivery are based on pre-received cell data, eliminating the need for complex continuous communication infrastructure.
Solution Approach 2:
The mobile receiving device performs self-service by autonomously determining its position, identifying which cell it is in based on stored cell data, and receiving appropriate services without requiring complex back channel communication with the broadcasting system. The device independently matches its location to cell definitions and retrieves relevant service information.
Data Source
AI summary
To perform location-specific services of a broadcasting unit, virtual cells for the location-specific services are set up so that cell data, which define a local cell area, are transmitted to a mobile receiving device via the broadcasting unit. The cell data are stored in the mobile receiving device. The mobile receiving device establishes its current position and determines whether it is located in the cell area. If the mobile receiving device is located in the cell area, the receiving device performs a service assigned to the cell data. The setting up of cells for location-specific services by the broadcasting unit in a multitude of mobile receiving devices in the service area of the broadcasting unit enables geographical areas inside and outside the service area to be slit up into smaller, interactive and virtual service cells and cell clusters in a dynamic and optimal manner.
