In a typical use case the agent will communicate sim state change (card removed or not accessible) to sap server. Based on that, the sap server should make a decision whether disconnect or not. What's more the disconnect procedure is defined in the SAP spec, and would be nice to keep all those procedures in the sap server, not in the agent which will be specific for a sim provider.  Therefore, I would remove this method call from the api.  I would add the Disconnect signal instead.

Ok, In which all situations should the SAP server decide that the SAP 
connection has to be disconnected (you have mentioned Sim Status change 
as one candidate)?

Also, based on what should the server decide to initiate a "Graceful" or 
"Immediate" disconnection?
