The invention relates to a packet-switched radio system and to a method of
locating a subscriber terminal in a packet-switched radio system. In the
method (302) the core network of the radio system transmits a location
service request message to the radio network of the radio system; (304)
the radio network transmits information to a subscriber terminal in a
paging message that the subscriber terminal is requested to initiate the
location service; (306) the subscriber terminal that received the paging
message transmits a paging response message to the radio network; (308)
the radio network transmits the paging response message to the core
network; (310) the network part locates the subscriber terminal on the
basis of the information included in the paging response message.
