Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE femtocell-based content service systems face challenges in efficiently connecting user equipment to an evolved packet core network and selectively providing various types of data, such as text and high-definition images, through a femtocell network, while managing system information and query data effectively.
Innovation Solution
The system connects user equipment to an evolved packet core network through a radio network subsystem and a home eNode subsystem with a femtocell, using a content service server to retrieve and provide corresponding content based on system information including PCI, U_DL BW, Cell ID, TAC, HeNB Name, and SNR, and query data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system provides both small amount of data (text, image) and large amount of data (high definition image) through femtocell network, then the adaptability and service versatility are improved, but the device complexity and data management difficulty increase
Solution Approach 1:
The patent segments data into different categories (small amount of data including text and images, and large amount of data including high definition images) and manages them through separate processing routes. The content service server distinguishes between these data types and applies different transmission strategies, thereby reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The system dynamically adjusts data transmission based on real-time conditions including user equipment location, network status, and data type requirements. The content service server selectively provides data based on current network conditions and user needs, enabling adaptive service delivery without requiring complex static configurations.
2Adaptability or versatility
If the system connects user equipment to EPC network through multiple routes (RNS and HeNS with femtocell), then the network connectivity and service coverage are improved, but the measurement and detection difficulty increase
Solution Approach 1:
The patent introduces a content service server as an intermediary that manages the complexity of multiple network routes. This server receives system information from both RNS and HeNS routes, processes and stores it in a database, and uses it to make intelligent data transmission decisions, thereby simplifying the detection and measurement of network conditions.
Solution Approach 2:
The system implements feedback mechanisms where the content service server continuously monitors network conditions, user equipment status, and data transmission effectiveness. This feedback information is used to adjust future data provision decisions, making the system more adaptive while reducing the manual detection and measurement requirements.
3Productivity
If the content service server retrieves and provides content based on system information and query data, then the data management efficiency and service delivery speed are improved, but the information processing complexity increases
Solution Approach 1:
The content service server performs preliminary actions by pre-retrieving and storing relevant content in its database based on system information received from the network. This pre-processing reduces the complexity of real-time data selection and transmission, thereby improving productivity while managing information processing complexity through advance preparation.
Solution Approach 2:
The system changes parameters such as data transmission rate, content type, and delivery method based on system information including PCI, U_DL BW, Cell ID, TAC, HeNB Name, and SNR. By dynamically adjusting these parameters, the system optimizes data provision efficiency without requiring overly complex processing logic.
