MPTCP Proxy in Cellular Networks for Link Budget Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in ensuring accurate signal transmission and reception while maintaining battery life, especially with the increasing demand for advanced features and the development of new wireless communication standards like 5G, where devices may experience link budget limitations.
Innovation Solution
Implementing a multipath transmission control protocol (MPTCP) proxy in cellular networks to provide addressable or transparent proxy support, enabling wireless devices to benefit from MPTCP communication even when end-to-end MPTCP is not supported, through IP address and port information provisioning, handover management, and policy provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end-to-end MPTCP communication is implemented, then connectivity and power efficiency are improved, but device compatibility and network complexity increase
Solution Approach 1:
The patent introduces an MPTCP proxy as an intermediary component deployed in the network (at gateway or edge router) that translates between standard TCP and MPTCP protocols. This allows MPTCP benefits to be achieved without requiring end-to-end MPTCP support, thereby improving compatibility while maintaining connectivity enhancements for MPTCP-capable devices.
2Use of energy by moving object
If MPTCP proxy is applied uniformly to all flows, then power consumption is reduced, but device autonomy and service quality deteriorate
Solution Approach 1:
The patent implements dynamic MPTCP proxy application where the proxy is selectively activated or deactivated based on service type, device capability, and network conditions. The network can dynamically provision MPTCP proxy information to specific devices for specific flows, allowing flexible control that balances power savings with device autonomy and service quality requirements.

AI summary
This disclosure relates to techniques for providing a multipath transmission control protocol proxy in a cellular network. A wireless device may establish a wireless link with a cellular network. The wireless device may provide an indication that the wireless device is multipath transmission control protocol (MPTCP) capable to a core network entity of the cellular network. The wireless device may receive MPTCP proxy information for a MPTCP proxy comprised in the cellular network from the core network entity. The MPTCP proxy information may include MPTCP server IP address and port information. The wireless device may establish a first MPTCP flow with the MPTCP proxy comprised in the cellular network via the wireless link.
