Title:
APPARATUS AND MECHANISM TO REDUCE MOBILITY INTERRUPTIONTHROUGH DUAL RRC IN WIRELESS NETWORK
Document Type and Number:
WIPO Patent Application WO/2020/087366
Kind Code:
A1
Abstract:
These disclosed embodiments describe a method for a UE and network to perform interruption-optimized HO. One type of HO command is transmitted by the source gNB. In novel aspect, UE is in the tentative dual RRC upon reception of the interruption-optimized HO command. In the tentative dual RRC, UE may has two RRC entity, one for the source gNB and the other is for the target gNB. In one embodiment, two SRB1s are established. One is used for RRC message transmission/reception to/from the source gNB and the other is used for the target gNB. Furthermore, RLM is performed for the source cell even when UE is in tentative dual RRC. UE transfers to single RRC state when the connection with the source is released.
