SMSC example - Core retries to Mobile, first SS7 than SIP
The core starts a delivery attempt towards a mobile. First SS7 is attempted but the HLR (SS7 domain) gives a negative response. Then the HSS (SIP domain) is tried, which answers with a positive reponse. The delivery attempt is done over SIP and the mobile accepts the message. Mainly positive choices are made, which makes the msg-flow easier. Currently no status reports are implemented in the Simple-SMSC model, but you will see that there are already many (millions) permutations. Use the choices on the right to make different diagrams or even different starting points (e.g. App, UCP, CIMD2, SMPP, UE, SIP, SS7 or CORE).

You can and paste the above flow representation in a text file or in your favourite text editor using a monospace font. Ofcourse you will loose the context sensitive output and the links towards additional information.
The decission table shows which decissions have been made so far and which to make. The header contains the choice number and the entity making the choice. The choices are shown from left (latest) to right (earlier) which make it handier to follow or adapts. All choices you could have choisen on a specific level are displayed. You can click on the description to make a different choice.CORE-flows : The core starts a delivery.
