11 State transition model

03.723GPPCall Deflection stage 2TS

Figure 11.1 shows the successful cases of transition between the applicable logical states of the Call Deflection service. The state changes are caused by actions of the service provider.

Note that error cases are not shown in the diagram as they normally do not cause a state change. Additionally, some successful requests may not cause a state change and are therefore not shown in the diagram.
