Abstract
A local radio access information transmitter (LRAIT) may be used in a communications area serviced by multiple different radio access technologies (RATs) allocated to different radio resources in different locations in the communications area. Each RAT is associated with RAT radio transceiver(s) for serving UEs in the communications area. The LRAIT is in addition to the RAT transceivers and located near a hotspot service area in the communications area. The LRAIT determines local radio access information (LRAI) including different RATs available in the hotspot service area and frequenc(ies) of operation allocated to each RAT in the hotspot service area, sends a registration message to a wide area radio access information controller, and based on a response therefrom, determines what radio resources to use to transmit the LRAI signals. The LRAIT transmits the LRAI signals for receipt by UEs in the hotspot service area using those radio resources.
