The present disclosure relates to a user equipment (UE), comprising a processor, which determines that a transmission of small data is to be performed. The UE is in an inactive state with at least one data connection to a radio base station. The UE is assigned at least with a cell-specific UE identification and a non-cell-specific UE identification. The processor determines which UE identification to use for the small data transmission, based on whether the UE, after having transitioned to the inactive state, has moved to the current radio cell from another radio cell. In case the UE has moved to the current radio cell from another radio cell, the non-cell-specific UE identification is used. In the other case, the cell-specific UE identification is used. A transmitter transmits a control message including the determined UE identification and transmits the small data using one of the at least one data connection.

The application relates to the field of wireless communication, and discloses a roaming method in a multi-link scenario, a multi-link device and a storage medium. The roaming method in the multi-link scenario includes: selecting a target network access device that meets a condition; disconnecting a logical entity on a secondary link of an original network access device from the original network access device; establishing a connection of the logical entity with the target network access device; determining a link through which the logical entity is connected with the target network access device as a primary link; and disconnecting a connection of the other logical entity other than the logical entity with the original network access device. The application realizes roaming of a terminal among different network access devices through link management and interactive control, ensuring service continuity and avoiding packet loss.

A system described herein may provide a technique for the predictive determination of regions, such as registration areas associated with a wireless network, with respect to a User Equipment (“UE”) that registers with the wireless network. Such registration areas may be associated with different services, Quality of Service (“QoS”) parameters, network slices, or the like. When registering with the wireless network, the UE may receive an indication of a registration area that includes multiple tracking areas, which include a tracking area in which the UE is currently located and one or more other tracking areas in which the UE is likely to enter, as predicted based on one or more artificial intelligence/machine learning (“AI/ML”) models. The prediction may be based on the current location of the UE, UE attributes or parameters, and/or historical location information associated with the UE and/or other UEs.
