The ITU-T has subsequently published CS2, CS3 and CS4, all of which are successors and enhancements to CS1. The European Telecommunication Standardization Institute (ETSI) has used the work from ITUT to endorse IN standards for the European market. 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.
In that way, the supplementary service is personalized for that subscriber. Similarly, the transfer of CAMEL subscription data from HLR to MSC/VLR personalizes the CAMEL service invocation for a subscriber. 1 Location Update Procedure When a GSM CAMEL subscriber registers in an MSC/VLR, CAMEL capability negotiation takes place between HLR and VLR. This negotiation entails that the HLR determines whether the subscriber is allowed to register in that VLR and which CAMEL data shall be sent to that VLR.
78  specifies, however, that the corresponding parameter in the initial DP operation is syntactically optional. Stage 2 is leading in this regard, meaning that the initial DP operation shall always contain IMSI. 78  specifies that an IN service may provide a no answer timer value in the range 10–40 s. 78 , application timer, has a range of 0–2047 s, but again, stage 2 is leading with a range of 10–40 s. A parameter that is specified in stage 3 may be used by different stage 2 information flows.
