9 Implementation of PAM service using IN approach

This clause provides an example of the implementation of the PAM service in convergence of PSTN and UMTS
or ANSI-41/cdma2000 network. The implementation of the PAM service uses the intelligent network
approach. The PAM service is realized by introducing the PAM-SCP with service logic and data to support the
PAM service and with the support of the HLR/AuC (HSS). The advantage of this implementation is that there
is no impact on the underlying fixed network and mobile core network. Some adaptations to the components
at the application layer are required as described in clause 9.2.

In the following figures, a suitable short range air interface such as [b-Bluetooth] or [b-IEEE 802.11g] is used
between the AP and the mobile station.

9.1 Network configuration
Figure 7a illustrates the network configuration of the PAM service with PSTN access to a GSM/UTRAN
network using MSISDN as the PAM service number.

Figure 7b illustrates the network configuration of the PAM service with PSTN access to an ANSI41/cdma2000
network using MSISDN as the PAM service number.
