Abstract: Proposed are a CHO resource processing method, apparatus and system. The CHO resource processing method comprises: a source base station of a UE sending CHO resource change request indication information to at least one CHO target base station of the UE, the CHO resource change request indication information being used for instructing at least one CHO target base station to change the resource of at least one CHO target cell of the UE; and the source base station sending a CHO resource change notification to the UE, the CHO resource change notification comprising information indicating the change in resource of at least one CHO target cell and an identifier of at least one CHO target cell.

Abstract: Methods and systems for handling UE associated information in non-terrestrial networks are disclosed. In one embodiment, a method performed by a satellite head station, includes: translating a first uplink (UL) tunnel address associated with a core network to a second UL tunnel address associated with the satellite head station, wherein the first and second UL tunnel addresses are each associated with a packet data unit (PDU) session established between the core network and a user equipment device (UE); transmitting the second UL tunnel address to a first satellite base station; and receiving UL data associated with the PDU session from the first satellite base station, wherein a UL tunnel address destination associated with the received UL data is set as the second UL tunnel address.

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 an address coordination method and device, a base station, a session management function (SMF) network element and a storage medium. In a handover process of a terminal from a source base station side to a target base station side, a UPF split state of a PDU session of the terminal may be determined and data transmission tunnel address coordination may be implemented, thereby enhancing flexibility of split control of the PDU session in the handover process of the terminal, preventing the target base station side from executing PDU session resource modify/modification indication and other processes again to perform the data transmission tunnel address coordination after the terminal completes the handover. Resource admission control efficiency of the target base station side can be improved, so that the PDU session enters a reasonable state of UPF split or UPF non-split as soon as possible, and signaling resources between the target base station side and a core network can be saved.

Abstract: Provided are a connection method, a configuration updating method, a control plane device and a user plane device. The method includes: transmitting, by a control plane device, a first request message for establishing a connection to a user plane device, where the first request message for establishing the connection includes information about the control plane device; and transmitting, by the user plane device, a first response message indicating that the connection is successfully established or a first response message indicating that the connection fails to be established to the control plane device, where the first response message indicating that the connection is successfully established includes information about the user plane device, and the first response message indicating that the connection fails to be established includes the information about the user plane device and a reason why the connection fails to be established. Further provided is a storage medium.

Abstract: Methods and devices for using an unlicensed carrier resource are provided. In a method for using an unlicensed carrier resource, an eNode B (eNB) receives indication information reported by a User Equipment (UE), where the indication information is used for indicating that a local Secondary Cell (Scell) of the UE is idle; upon a trigger of the indication information, the eNB detects whether a local Scell of the eNB is idle or not; and the eNB judges, according to a detection result, whether or not to use an unlicensed carrier resource which has been occupied by the UE.

Abstract: An integrated wireless sensing and communication (ISAC) system may allow for a radio access network (“RAN”) node to improve the sensing. There may be a secondary sensing radio link (S-S-RL) for additional sensing functionality. The sensing signal can be used by the RAN node and/or the UE for detecting objects along a radio path between the RAN node and UE to improve the wireless communication through RL. The S-S-RL may be added in a single connectivity system or may be modified in a dual connectivity system. In order to maximize the sensing collaboration benefits among RAN nodes, the S-S-RL can assist communication or assist sensing.
