Patent attributes
A wireless telecommunications system may be configured to provide wireless service via unlicensed, licensed, and/or shared frequency bands (e.g., frequency bands that are shared with other telecommunications systems, and for which access is regulated by an external entity). A load balancing technique, described herein, may provide load balancing between licensed and shared frequency bands based on relative load of the licensed and shared networks, and/or other factors (e.g., a priority access license (“PAL”) of a base station to which the user device is attached). Techniques described herein may be useful in carrier aggregation, in which a user device may simultaneously attach to multiple carriers (e.g., a licensed carrier, along with a shared carrier and/or an unlicensed carrier).
