    Abstract: Provided are an address allocation method and apparatus, a core network, a node, a network system and a medium. In at least one of the case of establishing a session, at least two uplink addresses are configured and send to an access network. The access network is a connectivity network formed by a coupling of at least two network element nodes. At least part of the at least two uplink addresses are used for being allocated among the network element nodes. The access network receives the at least two uplink addresses sent by the core network and allocates the at least two uplink addresses. The access network sends at least one downlink address to the core network and determines usage of the uplink addresses. The access network may determine a correspondence between the uplink address and the downlink address. The core network receives the downlink address.

    Abstract: Presented are systems, methods, apparatuses, or computer-readable media for data forwarding for user equipment with data transmission. A non-anchor node may receive user data of a wireless communication device to send uplink. The non-anchor node may decode the user data into an uplink air interface protocol protocol data unit (PDU), using a partial portion of context information of the wireless communication device. The non-anchor node may send the uplink air interface protocol PDU in a user data container of a first message, to an anchor node having full context information of the wireless communication device.

    Abstract: Provided are a network processing method and apparatus, a core network, a base station and a computer readable storage medium. A core network side initiates an NG interface terminal radio capability check request message to a master base station, the NG interface terminal radio capability check request message including terminal radio capability information of a plurality of base stations accessed by a terminal via dual-connectivity or multi-connectivity; and then the core network side receives an NG interface terminal radio capability check response message fed back by the master base station, the NG interface terminal radio capability check response message at least carrying indication information of whether the base stations support a specific service.

    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, and signaling resources can be saved.

    Abstract: Provided are method and apparatus for maintaining an air interface inactive state. The method includes: receiving an RRC uplink notification message sent by a UE, the RRC uplink notification message carrying information notifying that the UE is out of coverage of a serving cell under a source secondary node; performing, based on the RRC uplink notification message, a migration operation of a related high-level configuration of a PDU session anchored to the source secondary node by the UE, a migration target node being a target secondary node or a current master node; and sending an RRC downlink reply message to the UE after performing the migration operation of the high-level configuration, and maintaining the UE in a dual-connectivity or single-connectivity air interface inactive state.

    Abstract: Provided are a method, a device, equipment and a storage medium for managing a mobile handover. When the method for managing the mobile handover is applied to a source secondary base station, the method includes: in response to determining to switch a set user equipment (UE) to a target base station, sending a handover request message to the target base station; and in response to receiving a handover request acknowledgement message sent by the target base station, sending a handover command message to the UE by using a signaling radio bearer (SCG SRB) of a source secondary base station side to trigger the UE to perform a random access attempt on a serving cell under the target base station.

    Abstract: Provided are a CHO resource processing method, apparatus and system. The CHO resource processing method includes: sending, by a source base station of a UE, CHO resource change request indication information to at least one CHO target base station of the UE, where the CHO resource change request indication information is configured for indicating the at least one CHO target base station to change a resource of at least one CHO target cell of the UE; and sending, by the source base station, a CHO resource change notification to the UE, where the CHO resource change notification includes information indicating that the resource of the at least one CHO target cell is changed and an identifier of the at least one CHO target cell.
