Patent ID: 11778684

Abstract:
Embodiments include methods in a wireless device. Such methods include, while the wireless device is in an RRC inactive state with respect to a wireless communication network, determining that updates are needed for the wireless device's access stratum (AS) and non-access stratum (NAS). For example, the AS update can be a RAN notification area update (RNAU) and the NAS update can be a tracking area update (TAU). Such methods include transmitting, to the wireless communication network, a request to resume an RRC connected state with the wireless communication network. The request includes a cause indicator that indicates mobility signaling as a cause for resuming the RRC connected state. Such methods also include receiving, from the wireless communication network, a response to the request to resume the RRC connected state and initiating the NAS update based on the response. Other embodiments include wireless devices configured to perform such methods.
