Concepts and technologies are described herein for cell broadcast for signaling resource load from one or more radio access networks (“RANs”). According to one aspect disclosed herein, a base station can collect signaling load information of the base station. The base station can also generate a cell broadcast message that includes the signaling load information. The base station can also send the cell broadcast message to a target mobile device. The target mobile device can be configured to determine, based at least in part upon the signaling load information, to which radio access network of a plurality of radio access networks to connect.
