All fields in the
Initial DP SMS script entry parameters
may be used as selectors or source values. The initialdpsms field will be populated as per the relevant
INAP ASN.1 in use.
These selectors are available for all rules, including action rules.
Note that the input. prefix is included here for clarity, but is not required as it is
the default N2SVCD rule engine namespace.
Subscriber Information Selection
When an Initial DP SMS message is received for processing, subscriber details are extracted as:
- IMSI: taken from the IMSI digits, if present.
- MSISDN: differs depending on the SMS direction.
- Originating SMS: taken from the calling party.
- Terminating SMS: taken from the destination subscriber.
The specific protocol field that these values are drawn from will depend on the relevant INAP ASN.1 for the INAP variant in use.
