System and Method of enhanced call control through SMS based protocol

A system for enhanced call control through SMS based protocol, comprising:

• a mobile handset optionally equipped with application client programmed to:
• monitor user input to a mobile handset to intercept selected cellular telephone calls launched using the mobile handset or any other actions related to controlling of existed connected calls;
• provide user interface for account related actions such as but not limited to adding or removal terminals from the controlled group, manipulation with specific calling group like simultaneous call (SIM) group or haunting group, association of controlled terminal with specific personal access numbers (DID) and others;
• provide user interface for advanced call control actions such as but not limited to 3d party call control features, different types of conference and transfer and others;
• monitor the location of the mobile handset;
• select SMSC number based on the location of the mobile handset;
• send an SMS call control message (SMSCCM) containing the called number or numbers that should be controlled, location, authentication credentials and other information to the call control application server (CCAS) through certain SMSC number;
• and launch or answer necessary telephone calls from the mobile cellular handset as result of these call control actions;
• and a call control application server (CCAS), comprising a service programmed to:
• receive this SMSCCM by CCAS and process it;
• authenticate the user who sent the message based on provided credentials, SMS origination number or other ways;
• initiate call control functionality such as but not limited to call establishment between different subscribers, 3d party call control features, different types of conference and transfer, adding or removal terminals from the controlled group, manipulation with specific calling group like simultaneous call (SIM) group or haunting group, association of controlled terminal with specific personal access numbers (DID) and others according to command received in SMSCCM on behalf of subscriber's account.

A mobile handset application client, comprising:

• program instructions for monitoring user input to a mobile handset to intercept selected cellular telephone calls launched using the mobile handset or any other actions related to controlling of existed connected calls;
• providing user interface for account related actions such as but not limited to adding or removal terminals from the controlled group, manipulation with specific calling group like simultaneous call (SIM) group or haunting group, association of controlled terminal with specific personal access numbers (DID) and others;

• and launching or answering necessary telephone calls from the mobile cellular handset as result of these call control actions.

A call control application server, comprising:

• a service application that receives this SMSCCM by CCAS and processes it;
• extracts location information, subscriber identification and call control commands;
• authenticates the user who sent the message based on provided credentials, SMS origination number or other ways;
• initiates call control functionality such as but not limited to call establishment between different subscribers, 3d party call control features, different types of conference and transfer, adding or removal terminals from the controlled group, manipulation with specific calling group like simultaneous call (SIM) group or haunting group, association of controlled terminal with specific personal access numbers (DID) and others according to command received in SMSCCM on behalf of subscriber's account.
