Abstract
A cellular communication network may be configured to use a primary Long-Term Evolution (LTE) base station and a secondary New Radio (NR) base station to implement a Non-Standalone Architecture (NSA) configuration. The primary LTE base station broadcasts system information, for reception by the communication device, using System Information Blocks (SIBs). The secondary NR base station, however, may be configured to not broadcast certain system information. Rather, system information of the NR base station is specified to the communication device in communications from the LTE base station during setup of an NR data connection. When there is a change in the system information of the NR base station, the network is configured to forgo updating the communication device with the new system information at least until the existing NR data connection is terminated.
