An IP Multimedia Subsystem Service Control Point (IMS-SCP) module of a carrier network may provide trigger management for a request for a circuit switched (CS) call. For example, an IMS-SCP module may receive an request for a CS call associated with a user equipment. The IMS-SCP module may determine handling of the request for the CS call includes one or more first operations by a first feature platform and one or more second operations by a second feature platform. In response to the determining, the IMS-SCP module may perform trigger management associated with the request for the CS call. The trigger management may include invoking, by the IMS-SCP module, the one or more first operations of the first feature platform and, subsequent to the invoking the one or more first operations, invoking the one or more second operations of the second feature platform.

Trigger management for roaming calls in IMS networks

The disclosed embodiments include a method for offline charging performed by an anchoring node of a telecommunications network. The anchoring node can send a request to an online charging system (OCS), where the request is for online metering of a call by a subscriber of the telecommunications network. The anchoring node may obtain an indication of an exception to the online metering of the call. In response, the anchoring node can perform a default call handling (DCH) procedure to allow the call on the telecommunications network despite an inability to perform the online metering. The anchoring node also generates a modified charging detail record (CDR) that includes an indication of the exception. The anchoring node can then send a message, which includes at least an indication of the modified CDR, to enable a mediation server to perform offline charging for the call.

Offline charging of communications services

A monitoring application and method in a disabled telecommunication device for monitoring communication sessions initiated by the device and detecting an emergency communication session that is initiated by the device. If an emergency communication session is detected, the monitoring application generates and transmits a message to a rating engine over a non-voice channel. The non-voice channel may be an unstructured supplementary service data (USSD) channel, a short message service (SMS) channel, or other like messaging channel. When the message is received via the non-voice channel, various callback techniques may be implemented to allow the disabled device to receive communications after the emergency communication session, even though such communications would normally be prevented as a result of a service lock.
