Method and device for conditionally adding and changing cell
摘要
說明書
The MN having received a message in operation 7-50 may identify a T-SN, based on received information. For example, the MN may recognize a particular t-SN, based on a transaction ID of a T-SN, or distinguish a t-SN, based on a conditional configuration ID of a target PSCell of conditional PSCell addition. When the terminal transmits, to the MN, a corresponding message including ID information of a T-SN selected as a target, and a target cell ID (information on a candidate ID, or a conditional PSCell config ID, PCI, or CGI) in operation 7-50, the MN may recognize a particular T-SN, based on information included in the message. The MN may transmit a base station reconfiguration complete message to the identified T-SN (operation 7-55). For example, the message may be an SgNBReconfigurationComplete message. The MN may include an SN RRC reconfiguration complete message received in operation 7-50 in the SgNB Reconfiguration complete or ULInformationTransferMRDC message, and may transfer same to a T-SN selected as a target SN (operation 7-55). In this case, a separate RRC message may include an NR complete message so as to be transferred. In this embodiment, when PSCell addition or change is determined, the terminal performing a PSCell addition or change operation does not transmit an RRC reconfiguration complete message or an NR complete message to a selected PSCell, and transmits same to the MN, and the MN transfers information (an SN RRCReconfigurationComplete message) received from the terminal to a target PSCell or a T-SN controlling the target PSCell.
