Claim 10:
11. A method of access control, being applied to a base station supporting new radio access to an unlicensed spectrum, comprising:
determining a first system information block based on a supported traffic type, wherein the first system information block carries at least one of: a correspondence between traffic type and maximum number of times for transmitting a preamble or a correspondence between quality of service class identifier and maximum numbers of times for transmitting a preamble; and
broadcasting the first system information block;
wherein the maximum number of times for transmitting the preamble is larger for delay-insensitive traffic types than for delay-sensitive traffic types, such that the user equipment is capable of performing LBT detection on the unlicensed channel for more times, and avoiding prematurely reaching the maximum number of times for transmitting the preamble and random access failure when the unlicensed channel is busy, and selecting other ways to access a network for the delay-sensitive traffic types, thereby improving access success rate and efficiency of traffic data transmission.
