Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for accessing Internet Protocol Television (IPTV) networks primarily utilize wired networks, failing to provide a means for terminals to access IPTV networks via wireless networks, which does not meet the requirements for actual use scenarios.
Innovation Solution
A method and apparatus that enable terminals to access IPTV networks using wireless networks by obtaining and sending access messages with authentication information through user plane and session management network elements, facilitating authentication and session establishment, and managing address allocation to allow seamless access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal uses a wired network to access the IPTV network, then the access is stable and reliable, but the adaptability to different network scenarios is limited
Solution Approach 1:
The patent enables the terminal to access the serving network through multiple network types (wired and wireless) by implementing a unified access method that works across different network interfaces. The user plane network element handles both wired and wireless access messages, making the system universal and adaptable to various network scenarios while maintaining consistent access procedures.
Solution Approach 2:
The user plane network element acts as an intermediary between the terminal and the serving network. It receives access messages from the terminal regardless of whether the access is wired or wireless, performs necessary processing including adding authentication information, and forwards the messages to the serving network. This intermediary approach abstracts the network type differences and ensures reliable access handling.
2Adaptability or versatility
If the user plane network element processes and adds authentication information to access messages, then the access functionality is enhanced, but the device complexity and power consumption increase
Solution Approach 1:
The patent divides the access message processing into distinct functional segments: the user plane network element handles message reception, authentication information addition, and forwarding, while the session management network element handles authentication verification. This segmentation allows each component to focus on specific tasks, reducing overall system complexity while enhancing processing capability.
Solution Approach 2:
The user plane network element automatically adds the necessary authentication information to the access message without requiring complex manual configuration or intervention. The system uses pre-established authentication mechanisms and automatically retrieves and attaches the required authentication data, simplifying the processing workflow while maintaining enhanced functionality.
