SmartTrust DP gives the choice of IP messaging supported by handset and SIM as well as the option to avoid delivering OTA messages while a subscriber is not in its home network.

With the expanded platform, the SIM can initiate an IP session with the SmartTrust DP HTTP server module. Additionally, SmartTrust DP supports polling by the SIM client, enabling periodic checks by the client to determine if a management session is required.

Beyond messaging, the platform implements functionality and services for event reception interfaces, configuration management, charging, user administration, operation and maintenance, logging, statistics, reports, data storage and an API for external access to the unified repository, says G&D.

Additionally, the modular architecture of SmartTrust DP allows mobile operators to deploy other applications such as SmartRoam for support of steering to LTE networks, SmartAct for managing LTE-specific files and SmartProvisioning for handling IMS and other data connectivity.
