TECHNIQUE FOR DIFFERENTIATED ACCESS CONTROL

摘要

A technique for random access, RA, to a radio access network, RAN, (504) for a radio communication involving a radio device (502) is described. As to a method aspect of the technique, system information (506) indicative of an association between RA preambles (508) for performing the RA and at least one of device categories for the radio device (502) and service requirements for the radio communication is received (302) from the RAN (504). At least one of the RA preambles (508) that is, in accordance with the association indicated in the system information (506), associated to at least one of a device category of the radio device and a service requirement of the radio communication is transmitted (306) to the RAN (504).
