Systems, apparatuses, and methods are described for wireless communications. A base station may send, to a core network entity (CNE), a message indicating a context release of a wireless device comprising paging assistance elements. The CNE may utilize one or more beam identifiers for paging the wireless device. The base station may remove the paging assistance information from memory. The CNE may send the paging assistance information back to the base station for paging the wireless device, thereby saving resources.
