Solution Overview

Problem

Current mobile data broadcasting systems face complexity and inefficiency in directional broadcasting, requiring direct connections between content servers and multiple broadcast networks, leading to increased network complexity and reduced security, as well as limitations in targeting specific location areas.

Innovation Solution

A method and system that process broadcast messages based on first and second location information, where the network element determines whether the message's location matches its own or nearby elements' locations, allowing for precise directional broadcasting without direct access to the target area, thereby reducing network complexity and increasing precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If content servers directly connect to multiple broadcast networks for directional broadcast, then broadcast coverage and service capability are improved, but network complexity and administrative workload increase greatly

Engineering Contradiction:
Improvebroadcast coverageVSAvoidnetwork complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a location server as an intermediary component that centralizes location information management. Instead of content servers directly connecting to multiple broadcast networks, the location server mediates by providing location information to content servers, which then interact with broadcast networks. This reduces network complexity while maintaining broadcast coverage capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The location server provides a universal service by managing location information for multiple broadcast networks and multiple content servers through a single interface. This multi-functional approach allows the system to maintain adaptability across different networks without requiring separate direct connections for each network-server pair.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If content servers directly connect to broadcast networks for directional broadcast, then service delivery capability is improved, but network security reduces

Engineering Contradiction:
Improveservice delivery capabilityVSAvoidnetwork security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The location server acts as a security intermediary that controls and manages access between content servers and broadcast networks. By centralizing location information management, it provides a single point of control for security policies, reducing security risks associated with multiple direct connections while maintaining service delivery capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If broadcast networks cover large ranges with few base stations, then network complexity is reduced, but precision of directional broadcast decreases

Engineering Contradiction:
Improvenetwork complexityVSAvoiddirectional broadcast precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments location information into hierarchical levels (location areas, base station areas, cell areas) that can be selectively used. This allows the system to maintain simple network topology with fewer base stations while achieving precise directional broadcast by utilizing detailed location information segments when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of location information granularity by storing and managing multiple levels of location precision (from broad location areas to specific cell areas). This allows dynamic adjustment of broadcast precision without changing the physical network structure, enabling precise directional broadcast even with fewer base stations.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If location areas are defined by broadcast network coverage, then network administration is simplified, but flexibility in targeting specific locations is lost

Engineering Contradiction:
Improvenetwork administrationVSAvoidlocation targeting flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments location information into multiple hierarchical levels (location areas, base station areas, cell areas, tracking areas). This segmentation allows the system to maintain simple broadcast network administration at the location area level while providing fine-grained location targeting flexibility by selecting appropriate segmentation levels for specific broadcast needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects which location information segment to use based on the specific broadcast requirements. For broad broadcasts, it uses location area level information; for precise targeting, it uses cell area or tracking area information. This dynamic adaptability maintains administrative simplicity while providing location targeting flexibility.

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments of the present invention disclose a method, a device and a system for implementing directional broadcast in mobile data broadcasting. In the method, upon receiving a broadcast message from a content server, a network element processes the broadcast message according to first location information carried in the broadcast message and second location information in the network element. In the embodiments of the present invention, with the first location information carried in the broadcast message and the second location information set in the network element, upon receiving the broadcast message, the network element processes the broadcast message according to the first location information and the second location information, so that the content server may implement directional broadcast for a special location area without directly accessing a directional location area, which reduces the network complexity.
