Each gateway registers itself as a mobile unit in the Home Location Register
(HLR) on the UMTS network. The gateway address is based on the Mobile
Station ISDN Number (MSISDN) that is operated by the device. In many
paging systems, users are assigned PINS that are used to authorize a caller
to deposit a message. This addressing problem can be solved by adding this
number to the gateway memory, or changing the gateway design to allow
the USIM card to cooperate with it. After this, the gateway is ready for the
next step. This is shown in Figure 3.6.
