A system may be configured to receive analytics information regarding a cell of a wireless telecommunications network. The cell may be associated with multiple carriers, which may each be associated with, for example, a particular radio access technology (“RAT”), frequency band, or frequency sub-band. The system may dynamically rank the carriers based on measures of load associated with the carriers (as indicated by the analytics information), and may generate system information blocks (“SIBs”) that include the dynamic rankings. The SIBs may be provided to user devices, which may select carriers, via which to connect to the cell, based on the dynamic rankings.
