A radio bearer processing method and a network device are provided. The method includes: establishing, when a first event is detected, a radio bearer (RB) with a mobile terminal, or refusing to establish the RB. The first event comprises at least one of: the secondary network device being added by a master network device accessed by the mobile terminal, configuration of the secondary network device being changed, or the mobile terminal being switched from another secondary network device to the secondary network device.

A mechanism is disclosed for performing data plane based routing during a handover. The mechanism includes executing a user plane function (UPF). An uplink packet is received from a user equipment (UE) anchored to a fifth generation radio access network (5G) base station (gNB). The uplink packet includes a change destination command, a destination field, and metadata including a destination address for the uplink packet. A change destination command in the uplink packet is executed by setting the destination field of the uplink packet to the destination address in the metadata. The uplink packet is transmitted to the destination address set in the destination field.

A terminal device includes: transmission circuitry that transmits a connection request to a first access point in order to connect, by a wireless link, to one of the first access point or a second access point each having a superframe in an initial state in which a control channel period is longer than a data channel period; and reception circuitry that receives, as a connection response, information indicating the second access point as information on a connection destination access point from the first access point after the connection request is transmitted.

Presented herein are techniques to support handovers in hybrid cell configuration environments. In one example, a method may include determining that a user equipment (UE) is connected to a first shared cell or a first unique cell of a radio access network; and causing a handover for the UE to a second shared cell or a second unique cell of the radio access network based on whether the UE is connected to the first shared cell or the first unique cell, wherein the handover is performed between one of the first shared cell and the second shared cell or the first unique cell and the second unique cell.

Disclosed are methods and systems for prioritizing cell selection for availing LADN services. A UE prioritizes cells for selection based on availability of LADN services in the cells. For handover, a base station of a cell, providing LADN services to the UE, prioritizes target cells that provide LADN services that are being currently availed by the UE for ensuring LADN service continuity. The base station initiates addition of secondary cells that provide additional LADN services that are intended by the UE. The UE can predict if a paging message is relevant to a LADN service and send serving requests to the serving cell or other cells to avail the LADN service. The UE detects relay UEs providing LADN services and prioritizes the relay UEs for selection based on availability of LADN services. The UE buffers data if the UE is located at an edge of a LADN service area.

Methods, devices, and systems related to wireless communications are disclosed. In one example aspect, a device for wireless communication includes a processor that is configured to receive an enquiry message from a base station enquiring capability information of the terminal device and transmit a response message to the base station indicating one or more templates of capability information determined according the one or more radio access technologies and a list of frequency bands.
