Again,
Early Call Forwarding:
Early Call Forwarding : Early Call Forwarding is Call Forwarding performed from the IPLMN before the call has been extended to the VPLMN of the forwarding subscriber (i.e. Call Forwarding Unconditional and Conditional Call Forwarding on Not Reachable known at the IPLMN before extension of the call)
Late Call Forwarding:
Late Call Forwarding: Late Call Forwarding is Call Forwarding performed after the call has been extended to the VPLMN of the forwarding subscriber (i.e. Conditional Call Forwarding on Busy, Conditional Call Forwarding on No Reply and Conditional Call Forwarding on Not Reachable detected in the VPLMN of the forwarding subscriber). Late Call Forwarding may be invoked in the IPLMN or in the VPLMN of the forwarding subscriber.
In summary, If call is forwarded by HPLMN then it is ECF if by VPLMN then it is LCF.
VAS charging: fixed charge is applied.

CAMEL: Customised Applications for mobile network enhanced logic
CAMEL is a facility, which uses IN service to allows the roaming subscribers to use special number like 1432 to access customer service as they use these numbers at home. When pre-paid subscribers make these kinds of calls, their HPMN gets call information from VPMN via CAMEL. This allows HPMN to subtract their purse. In turn VPMN charges the HPMN for letting its subscribers use their network.
CAMEL Invocation Fee (CIF) is basically a charge from VPMN to HPMN for letting HPMN’s subscriber use his network.
