S@T Gateway

Logos Solvo’s S@T Gateway provides access for a SIM based S@T browser to application content hosted on an application server. This enables the Mobile Network Operator to move functionality from the SIM to an application server, thereby saving valuable resources on the SIM. Applications are split, and only the most static components are stored on the SIM, with the dynamic elements hosted on the server.



Communication from the SIM based S@T browser is session based, making use of BIP (if supported by the handset and SIM) or SMS for the transmission of data in the browsing session. The S@T Gateway decodes requests from the browser, and relays these requests to the application server. Resulting responses from the application server are encoded and send to the SIM browser.

The S@T Gateway can initiate a browsing session to any supporting S@T SIM, using the extensive push functionality accessible trough the administration interface. The subscriber has the option to accept or reject the incoming browsing session.
