An originating mobile switching center of an apparatus in one example
handles one or more calls. A serving mobile switching center for a
communication device on a call of the one or more calls passes control of
the call to the originating mobile switching center. The originating
mobile switching center triggers the call to a service node. The service
node sends an initial trigger response to the originating mobile
switching center that instructs the originating mobile switching center
to redirect the call. The initial trigger response arms one or more
triggers that support one or more services for the communication device.
The one or more triggers comprise one or more of one or more switch based
triggers and one or more subscriber based triggers exclusive of
Calling_Routing_Addresss_Available, OAnswer, and ODisconnect triggers.
Upon receipt of the initial trigger response, the originating mobile
switching center encounters one or more of the one or more triggers and
triggers the call to one or more other service nodes.
