Methods for Suspending Inactive when Resuming and Resuming Inactive when Suspending

Abstract:

According to an aspect, a wireless device, operating in a wireless network, handles transitions from Radio Resource Control, RRC, connected state to an RRC inactive state. The wireless device receives (1502), from the wireless network, a message indicating either that the wireless device is to enter the RRC inactive state or that the wireless device is to remain in the RRC inactive state. The wireless device, responsive to the message, uses (1504), for inactive state operation, at least one previously stored inactive state parameter corresponding to a parameter omitted from the message.
