Cellular Network Reflection Entity for Localized Information Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Location Based Services (LBS) in cellular communication networks face inefficiencies in providing localized information services, particularly in terms of delay and processing requirements, as they often rely on destination-addressed messages and extensive processing within the network.
Innovation Solution
The implementation of a method using a network upload message with a payload part, recognized by a reflection entity within the cellular communication network, which generates and sends reflection messages to terminals in a predetermined spatial relationship with the service source terminal, enabling fast and localized information distribution without extensive processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If destination-addressed messages are used for localized information services, then information can be delivered to specific terminals, but processing requirements and delay increase
Solution Approach 1:
The patent applies the copying principle by creating reflection messages that are copies of the original network upload message. The reflection entity receives the original message and generates one or more reflection messages containing the same payload part, which are then sent to destination terminals. This copying approach eliminates the need for complex processing at each stage while maintaining the localized information delivery function, thereby reducing both delay and processing requirements.
Solution Approach 2:
The reflection entity serves as an intermediary between the service source terminal and the destination terminals. Instead of direct communication requiring extensive processing, the reflection entity mediates by receiving the network upload message, generating reflection messages, and distributing them to appropriate terminals based on spatial relationships. This intermediary approach simplifies the overall processing requirements while maintaining efficient localized information delivery.
2Productivity
If network upload messages with payload part are reflected to terminals in spatial relationship, then information distribution speed increases, but network infrastructure complexity increases
Solution Approach 1:
The reflection entity is designed with multi-functionality, serving as both a message receiver and a message generator/distributor. By consolidating these functions into a single network entity, the patent achieves fast information distribution without proportionally increasing overall network infrastructure complexity. The reflection entity can handle multiple operations (receiving network upload messages, generating reflection messages, determining spatial relationships, and distributing to multiple terminals) through a unified architecture.
Solution Approach 2:
The network upload message contains a payload part that is directly reflected and distributed without requiring extensive external processing. The reflection entity performs minimal processing by simply copying the payload part to reflection messages and distributing them based on pre-determined spatial relationships. This self-service approach enables rapid information distribution while keeping the processing burden on the network infrastructure minimal.
3Measurement precision
If extensive processing is performed within the network for LBS, then service accuracy improves, but delay increases
Solution Approach 1:
The patent applies preliminary action by pre-determining spatial relationships between terminals and the reflection entity. The network can pre-establish which terminals are in spatial relationship with potential service source terminals, so that when a network upload message is received, the reflection entity can immediately distribute the payload part to the correct destination terminals without performing extensive real-time processing. This preliminary preparation maintains service accuracy while significantly reducing delay.

AI summary
A method of providing a localized information service using an infrastructure of a cellular communication network is described. It comprises a service source terminal transmitting a network upload message to the cellular communication network, said network upload message comprising a payload part, a reflection entity of said cellular communication network receiving said network upload message, generating one or more reflection messages comprising said payload part, and sending said one or more reflection messages to a group of service destination terminals that stand in a predetermined spatial relationship with said service source terminal.
