10.3 Description of information flows

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

This subclause contains the detailed description of the information flows used by CAMEL for control and interrogation of subscription data.

Each Information Element (IE) is marked as Mandatory (M), Conditional (C), Specific conditions (S), mutually Exclusive (E) or Optional (O) in the "Status" column.

An ‘M’ IE shall always be included. A ‘C’ IE shall be included if the sending entity has the necessary information to populate the IE. The conditions for the inclusion of an ‘S’ IE are shown in the ‘Description’ column of the definition table. An ‘O’ IE may be included or omitted as required by the service logic. This categorization is a functional classification, i.e. it defines the requirements for the stage 2 information. It is not a stage 3 classification to be used for the ASN.1 syntax of the protocol.

The following principles apply for the handling of the IEs by the receiving entity:

– The gsmSCF and the IP-SM-GW may silently discard any IE which it does not functionally support.

– The HLR shall return an error if it does not functionally support an IE which it receives.

Details of errors and exceptions to these rules are specified in 3GPP TS 29.002 [34].
