Claim of US Patent No. 9,860,870

1. A wireless device configured to communicate with a Core Network (CN) node, the wireless device comprising:
a processor; and,
a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable
instructions to perform operations to:

determine a current downlink (DL) coverage class (CC) needs to be changed to a higher DL CC or a lower DL CC;
based on the determination of the need to change the current DL CC to the higher DL CC, transmit an indication of the higher
DL CC for the CN node by performing a cell update procedure; and,

wherein the determine operation and the transmit operation are performed at a predetermined time before a next occurrence
of a nominal paging group.
