Figure 1 – The functional model of the PAM service using a
discrete PAM service number

The functional model in Figure 1 follows the intelligent network functional model described in [ITU-T Q.1224].
The PAM-SCF is an SCF which supports PAM service logic and data.
The functional model shown in Figure 1 can be applied in case of different operators for the legacy PSTN/ISDN
and the mobile network and requires no special SLA between the fixed and mobile operators.
7.1.2 Architecture using MSISDN as the PAM service number

Figure 2 illustrates the functional model of the PAM service using a MSISDN as the PAM service number. The
PAM-SCF interfaces with HLR/AuC (HSS) in the mobile network. For simplicity, mobile station functions not
specific to the PAM service are omitted.

Figure 2 – The functional model of the PAM service using a MSISDN
as the PAM service number

Figure 2 applies equally to the CAMEL functional entities defined for a GSM/UTRAN network in [ITU-T Q.1741]
and to the equivalent WIN functional entities for an ANSI-41/cdma2000 network in [ITU-T Q.1742].
