4.5 Procedures for CAMEL

23.0783GPPCustomised Applications for Mobile network Enhanced Logic (CAMEL) Phase 4Release 17Stage 2TS

The SDLs in the present document illustrate how CAMEL modifies the normal call handling. They do not attempt to show all the details of call handling in nodes that support CAMEL. Relevant parts of 3GPP TS 23.018 [12] apply in addition to these SDLs. For example, some inputs leading to unsuccessful call attempts are not shown on these diagrams – corresponding clauses in 3GPP TS 23.018 [12] apply.

Note that in some SDL processes and procedures the Release information flow may be sent on both an access interface and an inter-switch interface. If the message is sent on a UNI, its effect is the same as a Release transaction information flow.

The text in this clause is a supplement to the definition in the SDL diagrams; it does not duplicate the information in the SDL diagrams.
