An Internet Protocol Multimedia Subsystem (IMS) device includes a memory configured to store a subscriber profile, where the subscriber profile includes at least one criterion relating to an event that occurs after a session request has been forwarded to a terminating party. The IMS device further includes a processor configured to invoke at least one application service for a session based on the at least one criterion in the subscriber profile.

Application service invocation based on filter criteria

At least one device receives a call request from a calling party to a called party. The device routes the call request to an Internet Protocol Multimedia Subsystem (IMS) core when a first condition is met and bypasses the IMS core when a second condition is met.

Network routing

An Internet Protocol Multimedia Subsystem (IMS) includes a Serving-Call Session Control Function (S-CSCF). The S-CSCF includes a Service Capability Interaction Manager (SCIM) configured to invoke one or more application services in response to a message being received by the S-CSCF.

Application service invocation

A system includes a policy engine in an Internet Protocol Multimedia Subsystem (IMS). The policy engine may be configured to store a group of policies associated with the IMS, and forward the group of policies to a group of policy components in the IMS.
