Abstract
A system and method for delivering and receiving Short Message Service (SMS) messages between users connected to satellite and cellular networks. The system includes a communication device capable of operating in both satellite and cellular modes, a satellite service provider, a satellite proxy network, and a cellular operator. The method involves monitoring the network mode of the user device, relaying information about the user device's connection to the satellite network via a specially formatted SMS payload and registering the user device with a cellular operator when in satellite mode. The satellite proxy network serves as an anchoring point for sending and receiving SMS messages, ensuring seamless message exchange between satellite network users and cellular network users. The user device is designed to automatically switch between satellite and cellular modes based on network availability, ensuring continuous communication. This invention enables improved messaging services and enhances communication between users on different networks.
