System and method for providing simplified programming constructs for user activities in a telecommunications application

A non-transitory computer readable storage medium including instructions stored thereon which, when executed by a computer, cause the computer to perform a method comprising the steps of:

• (a) receiving a plurality of SIP requests;
• (b) filtering the plurality of SIP requests;
• (c) initiating a UserActivity application in response to determining that one or more of said plurality of SIP requests represents a subscription to a UserActivity by a user;
• (d) processing said subscription to said UserActivity with said UserActivity application;
• and
• (e) transmitting one or more SIP responses from said UserActivity application.

A system for implementing user activities in a telecommunication network, the system comprising:

• a converged application server operating on one or more microprocessors;
• wherein the converged application server
• (a) receives a plurality of SIP requests,
• (b) filters the plurality of SIP requests,
• (c) initiates a UserActivity application in response to determining that one or more of said plurality of SIP requests represents a subscription to a UserActivity by a user,
• (d) processes said subscription to said UserActivity with said UserActivity application, and
• (e) transmits one or more SIP responses from said UserActivity application.
