Solution Overview
Problem
Mobile terminals face challenges in efficiently communicating with other devices across disparate wireless communication networks due to the variety of technologies and protocols used, and need a method to seamlessly transition between different access networks as the user moves.
Innovation Solution
A mobile terminal is equipped to establish and manage multiple communication sessions with a public network proxy, allowing it to control active communication paths and transitions between them, using different access networks and protocols, such as tunneling sessions over IP Security or VPNs, to facilitate data and voice communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile terminal is equipped to communicate with different types of networks using the same or different access technologies, then functionality is increased, but device complexity increases
Solution Approach 1:
The patent introduces a network proxy server as an intermediary that centralizes the complexity of managing multiple access networks and communication protocols. The mobile terminal communicates with the proxy server, which handles the intricate tasks of session management, path selection, and protocol adaptation across different networks (WiFi, cellular, Bluetooth), thereby maintaining terminal functionality while offloading complexity to the network infrastructure.
Solution Approach 2:
The network proxy server is designed as a universal communication hub that can interface with multiple types of access networks and protocols simultaneously. It provides a single point of contact for the mobile terminal while supporting diverse network technologies, allowing the terminal to access different networks without needing to implement complex multi-protocol handling itself.
2Reliability
If multiple communication paths are established over different access networks, then reliability is improved, but device complexity increases
Solution Approach 1:
The network proxy server acts as a mediator that manages multiple communication sessions and paths between the mobile terminal and other communication devices. It handles the complexity of establishing, maintaining, and transitioning between multiple tunneling sessions over different access networks, while the terminal only needs to communicate with the single proxy server, thus improving reliability without burdening the terminal with complex session management.
Solution Approach 2:
The system dynamically manages communication paths by allowing the mobile terminal to actively control which communication paths are active and to transition between them as needed. The network proxy server supports this dynamic behavior by facilitating smooth transitions between different access networks while maintaining continuous communication sessions, adapting to changing network conditions and terminal mobility.
3Ease of operation
If the terminal actively controls transition between communication paths, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The network proxy server serves as an intermediary that simplifies the control interface for path management. The mobile terminal can actively control transitions between communication paths by communicating with the proxy server, which handles the complex coordination required for seamless handoffs between different access networks. This maintains ease of operation for the terminal while managing control mechanism complexity through the proxy's centralized management capabilities.
Data Source
AI summary
The present invention provides a terminal capable of establishing multiple communication sessions with a public network proxy through different access networks. The terminal actively communicates with the public network proxy to control which of the multiple communication paths are active, as well as control the transition from actively using one communication path to using another. The public network proxy facilitates data and voice sessions between the terminal and any number of other communication devices. In one embodiment, the communication sessions are reserved tunneling sessions, and the terminal cooperates with the public network proxy to effectively control how many tunneling sessions are established, how many tunneling sessions are active at any given time, and the transition from one tunneling session to another for active communications. Each of the communication or tunneling sessions may be established over different access networks using different communication technologies and protocols.
