Abstract: Provided are a method, device and apparatus for acquiring information, and a computer storage medium. In the method for acquiring information, a first node receives a message transmitted by a second node, where the message is related to a cell group of the second node, each cell group includes one or more cells, and each cell belongs to a same wideband carrier. The first node acquires information on a cell under the second node from the message, that is, information on a cell in the each cell group. A device and an apparatus for acquiring information, and a storage medium are further provided.

Abstract: A wireless terminal receives a network identifier in a message received on a broadcast channel. The wireless terminal determines that a mobile network code in the network identifier corresponds to a non-terrestrial network. The wireless terminal updates a tracking area list of the wireless terminal by adding or deleting a tracking area identifier corresponding to the non-terrestrial network to the tracking area list.

Abstract: Provided are a handover method and apparatus. The method includes following steps: a UE receives an RRC reconfiguration message sent by a source base station, where the RRC reconfiguration message includes a list of target cells for performing a conditional handover by the UE, information of each target cell in the list of the target cells for performing the conditional handover includes at least one of the following: frequency information of the target cell, a physical cell identifier of the target cell, a conditional handover command of the target cell generated by the target cell, or at least one piece of measurement configuration identifier information, and the at least one piece of measurement configuration identifier information is used for instructing an execution condition for the UE to perform a conditional handover in the target cell; and the UE performs a handover according to the RRC reconfiguration message.

Abstract: Methods, apparatus, and systems for wireless communication are described. In one example aspect, a method includes performing, by a communication node, a handover procedure from a source base station to a target base station based on information associated with a Protocol Data Unit (PDU) session. The information indicates that at least one tunnel in a list of tunnels that carry user data has a one-to-one correspondence with a Quality of Service (QoS) flow. The method also includes transmitting, for the handover procedure, downlink data to both the source base station and the target base station by the communication node.
