System for exchanging information and data between communications networks and transmitters/receivers uses circuit switched data, data packets and short-messaging services

摘要

A first network/device (FND) (100) operates on a circuit switched data standard. A second network/device (SND) (300) handles data packets and operates on a short-messaging service standard. A data-exchange system (200) has a first access platform (AP) (210) to an FND interface (110) and a second AP (290) to an SND interface (310,320) between first and second APs.
