ABSTRACT
Roaming for voice, the ability for a user to
make and receive calls when visiting another
country, is taken for granted by GSM users
today. Currently GSM mobile operators are
introducing packet-based data networks (also
known as General Packet Radio Service) that
bring a huge variety of services. However, this
new network also introduces new complexity in
the support of the packet-based roaming scenario.
Due to the number of services, operators,
and users envisaged, it will be impossible
for operators to test all services for roaming in
all partner networks for GPRS; instead, the
capabilities of the network have to be tested.
Furthermore, mobile data service developers
must be aware that the network capabilities of
a visited (GPRS) network might differ from the
home network; thus, consideration is required
to ensure service continuity. This is especially
true as mobile operators start offering 3G networks
and support roaming agreements from
3G to 2G networks.
