Abstract
Embodiments of the present disclosure provide: dividing, by a base station, a frequency band of a cell into N frequency ranges, where the N frequency ranges include a common frequency range and a dedicated frequency range; sending, by the base station, information about the N frequency ranges and random access resource information of the cell to a UE; mapping, by the base station, a service bearer DRB of the UE into at least one frequency range of the N frequency ranges; and transmitting, by using a radio interface technology supported by the specified frequency range into which the DRB is mapped, a service carried on the DRB with the UE. A method for using a radio interface technology includes: using, by UE, a common frequency range, and optionally, using, by the UE, a dedicated frequency range to perform wireless network access.
