Embodiments of apparatus and method for uplink data plane management are disclosed. In one example, a method for handover continuity can include buffering data packets at a user equipment based on a trigger event. The data packets can be mapped to first quality of service flows and associated with first radio resources at a source network node. The method can also include identifying second quality of service flows associated with second radio resources at a target network node. The method can further include remapping from the first quality of service flows to the second quality of service flows. The method can additionally include transmitting the buffered data packets from the user equipment toward the target node based on the remapping.

A terminal according to one aspect of the present disclosure includes a receiving section that receives at least one of information related to a type of one or more transmission points installed in a movement path and information related to a transmit beam transmitted from the one or more transmission points, and a control section that controls reception of DL transmission transmitted from each of the one or more transmission points, based on the information being received.

A communication method, an access network device, a terminal device, and a core network device where the terminal device is handed over from a first access network device to a second access network device, the second access network device learns of first service progress of the first access network device based on a first sequence number of a data packet forwarded by the first access network device, without introducing additional progress exchange information between the two access network devices.

A Machine-to-machine (M2M) terminal (11) comprises a radio communication unit (111) and a controller (112). The radio communication unit (111) is configured to communicate with a base station (13). The controller (112) is configured to change at least one of a cell selection operation, a cell reselection operation, and a handover operation according to whether a specific coverage enhancement processing is required or according to whether the specific coverage enhancement processing is supported by at least one of a cell (13) in which the M2M terminal (11) camps on and a neighbouring cell (14) of the cell (13) which the M2M terminal (11) camps on. It is thus possible to provide an improved technique for allowing the M2M terminal that is supporting a special coverage enhancement processing for M2M terminals to camp on an appropriate cell.

This application discloses a roaming steering method, an apparatus, a device, a storage medium, and a system. In this application, a reference roaming steering condition is determined by an access control device by performing, for a plurality of times, a roaming steering test on one or more terminals belonging to a reference model, and the reference model is a model of a target terminal. Therefore, the reference roaming steering condition is similar to a roaming rule in the target terminal. In this case, when a first access point device obtains the reference roaming steering condition and determines that the target terminal satisfies the reference roaming steering condition, even if the target terminal does not unconditionally obey roaming steering of the first access point device, there is a high probability that the target terminal is successfully steered to roam.

A method for communication and related devices are provided in the disclosure. The method includes the following. A terminal device determines a failure of access to a target primary secondary cell (PSCell) or a radio link failure (RLF) after the target PSCell is accessed. The terminal device transmits a secondary cell group (SCG) failure report to a first network node, where the SCG failure report includes first indication information, and the first indication information indicates type information of PSCell addition/change.

Embodiments of the present disclosure disclose a cell selection or reselection method and a device, to resolve a problem that a terminal device cannot effectively and rapidly access a cell without taking a slice of the cell into consideration when performing cell selection or reselection. The method may be performed by a terminal device, and includes: receiving a MIB message from a cell; in a case of determining, based on the MIB message, that the cell can be a candidate access cell, reading a SIB message of the cell, where the SIB message includes slice information of the cell; and selecting one slice from slices of the cell to access based on slice information supported by the terminal device and the slice information of the cell.
