A digital mobile communication system is provided with a facility by means of
which
it can establish a connection to the Internet network (12) via an Internet
access point (14, 15). IAP settings needed for establishing a connection
are stored in a mobile station (MS). When a mobile station (MS) roams, the closest
point may, however, change, and IAP settings should be updated in the mobile station
(MS). The invention comprises dividing the mobile communication system into IAP
areas, which are given preferred IAPs. An IAP area may be e.g. a mobile communication
network (11, 17). Mobile communication networks broadcast system information
on the basis of which a mobile station may detect that the IAP area has changed
and start a procedure for updating IAP settings. Updating may comprise retrieval
of IAP settings from a special server (13) in the network maintained by
an Internet service provider. Retrieval can be done e.g. via a short message service
center (10). In one embodiment the mobile communication network broadcasts
messages giving recommended IAP settings to mobile stations.
