System(s) and method(s) are provided for regulating interaction amongst an application layer and a control layer in a packet-based core network. A data structure is provisioned in a centralized repository; the data structure includes (i) at least one procedure for regulating interaction amongst a session control component within the control layer and application server within the application layer, and (ii) an identification (ID) field attribute that uniquely identifies the data structure. To regulate such interaction, the session control component acquires a set of provisioned data structures; acquisition is automatic and can be dictated, in part, by generation of a data structure, or modification of an existing data structure or an ID field attribute. Based at least on an ID field attribute retained in a subscriber service profile, the session control component references a data structure identified by the ID field attribute and implements one or more procedures retained in such data structure. Implementation of the one or more procedure regulates the interaction between the session control component and the application server.
