Providing a dial-up connection in a packet radio system comprising at
least one mobile termination part, a terminal equipment part functionally
connected thereto, and a packet radio network. A first packet data
protocol context is activated between the packet radio network and the
mobile termination part for reception and transmission of packet-switched
data. A second packet data protocol context is activated between the
packet radio network and the mobile termination part for a dial-up
connection. The first context is deactivated in response to the second
context being activated. The second context is deactivated in response to
the dial-up connection being released. A third packet data protocol
context, substantially conforming to the first context, is activated in
response to the second context being deactivated.
