PROBLEM TO BE SOLVED: To enhance a connection method for mobile unit that efficiently utilizes radio resources. SOLUTION: In the UMTS(Universal Mobile Telephone System), semi-static uplink and downlink connection parameters relating to the frequently-used services of voice, fax, and web browsing are intermittently broadcast to mobile user equipment (20) which stores the parameters. When a mobile station requests (30) one of those services, the relevant dynamic parameters are sent over the radio interface and the mobile station is asked whether it has in its store the relevant parameters for the requested service, if so, the call is set up; if not, the semi-static parameters relevant to the requested service are sent to the user equipment.
