Example text

TC Begin – this TC message is used to initiate a TC dialogue; TC Begin may contain operations like initial DP, initiate call attempt or assist request instruction. • TC Continue – this TC message is used to continue or to terminate a TC dialogue (with prearranged end) and to transfer one or more CAP operations, CAP error or CAP result. • TC End – TC End is used to explicitly close a TC dialogue; this TC message may also contain one or more CAP operations. • TC Abort – TC Abort is used to abort a TC dialogue when an error has occurred requiring the closing of the TC dialogue, but the entity does not have the possibility to close the dialogue in a regular way.

2 Monitor Relationship When a monitor relationship exists between SSF and SCF, the IN service may keep informed about the call progress, but cannot assert any control over the call. It cannot, for example, order a follow-on call when call establishment fails. When a relationship exists between SSF and SCF, but does not qualify for a control relationship, it is a monitor relationship. A control relationship may downgrade to a monitor relationship, but not vice versa. 7 Evolution of the CAMEL Standard CAMEL is a natural evolution of the IN standards that were defined by Bellcore, the ITU-T and ETSI.

The ETSI CS standards are referred to as Core INAP CS1, Core INAP CS2 and Core INAP CS3. The present book does not aim to provide in-depth description of the original IN standards as developed by Bellcore, ITU-T and ETSI. Rather, the chapters in this book describe how CAMEL, 1 2 Bell Communications Research, North American laboratory, providing support to the Bell Companies. Other ITU sectors include radio communications (ITU-R) and telecom development (ITU-D). 1 Exchange Signalling IN control to basic call being an IN standard, is developed for the GSM network specifically.
