Abstract: For an incoming session intended for a user element, a domain selection function (DSF) is provided in a multimedia subsystem (MS) to select a circuit-switched subsystem (CS) or MS domain to use when routing the incoming session to the user element. Regardless of the domain in which incoming sessions are originated, the incoming sessions intended for the user element are routed to an S-CSCF in the MS. The S-CSCF directly or indirectly employs the DSF to determine whether to use the MS or the CS for terminating the incoming session. Based on available domain selection criteria, the DSF will select an appropriate domain, such as the MS or CS, to use for routing the incoming session to the user element. The domain selection decision of the DSF is provided to the S-SCSF, which will proceed by routing the incoming session to the user element via the selected domain.

Abstract: A system and method for protecting components of an IP telephony network whereby a protection scheme is enabled upon detection of resource exhaustion within the network that prevents delivery of incoming messages. Resource exhaustion may result from denial of service attacks and/or malfunctions in automated dialing systems. Once a protection scheme is enabled, the system activates mechanisms for identifying calling parties that are suspected of contributing to the resource exhaustion condition. These suspected calling parties may be placed in a blocked sender list, either manually or automatically. Calling parties may be presented with a challenge function in order to determine whether the call is being made by an automated dialing system. The system blocks incoming calls from calling parties identified in the blocked sender list either permanently or for a specified time duration. The protection scheme remains enabled for a specified duration or until the resource exhaustion condition has subsided.
