Document Type and Number:
WIPO Patent Application WO/2023/277764
Kind Code:
A3
Abstract:
Embodiments include methods for a user equipment (UE) configured for multi-radio access technology dual-connectivity (MR-DC) with a wireless network. Such methods include storingcontext information related to the UE's MR-DC. The context information includes a configuration associated with a secondary node for the UE's MR-DC. Such methods include receiving, from a master node for the UE's MR-DC, a first message that instructs the UE to release MR-DC and to suspend the UE's connection with the wireless network and, in response to the first message, releasing the MR-DC and suspending the UE's connection with the wireless network. Such methods include discarding at least part of the stored context information in response to one of the following: receiving the first message; a first indication included in or with the first message; or a second indication received from a target node for resuming the UE's connection with the wireless network.
