Method and apparatus for supporting scalable multi-modal dialog application sessions

An apparatus for maintaining a plurality of dialog sessions of a multi-modal dialog application, the apparatus comprising:

• a processor;
• at least one memory coupled to the processor, the at least one memory having stored thereon a sequence of instructions which, when loaded and executed by the processor, causes the processor to:
• store session state information for at least one suspended dialog session of a plurality of dialog sessions with the multi-modal dialog application, the session state information including a unique identifier;
• reduce an amount of the session state information stored;
• release resources associated with at least the amount reduced;
• and
• automatically resume the at least one suspended dialog session with the reduced session state information stored based on the unique identifier and a detected interaction with the multi-modal dialog application.

A non-transitory computer-readable medium having stored thereon a sequence of instructions which, when loaded and executed by a processor, causes the processor to:

• store session state information for at least one suspended dialog session of a plurality of dialog sessions with a multi-modal dialog application, the session state information including a unique identifier;
• reduce an amount of the session state information stored;
• release resources associated with at least the amount reduced;
• and
• automatically resume the at least one suspended dialog session with the reduced session state information stored based on the unique identifier and a detected interaction with the multi-modal dialog application.
