A master RAN node (1) associated with a master RAT (1) communicates with a secondary RAN node (2) associated with a secondary RAT and provides a radio terminal (3) with dual connectivity that uses the master RAT and the secondary RAT. In response to receiving, from the radio terminal (3) or a core network (4), terminal capability information indicating that the radio terminal (3) supports the split bearer, the master RAN node (1) uses a PDCP entity, which provides unified PDCP functionalities, for a master cell group split bearer for the radio terminal (3).

This disclosure handles a registration procedure in a UE supporting registration to 5GC via untrusted non-3GPP access network and 3GPP access network. More specifically this disclosure defines a UE behavior when a registration procedure is not successful to 5GC via first access network type (e.g. untrusted non-3GPP network access) after transmitting maximum number of registration request message via the first access network type to the 5GC and the UE is registered to 5GC via other access network type (e.g. 3GPP access network (NG-RAN)).

This application provides a network icon display method and device, and relate to the field of electronic technologies. The method comprises: A terminal device is connected to a long term evolution LTE cell and a new radio NR cell by using a dual connectivity technology, and the LTE cell supports a non-standalone NSA networking mode. The terminal device displays a 5G network icon. After disconnecting from the NR cell, the terminal device enters a 4G connected mode. If the terminal device meets a preset condition, the terminal device sends first request information to a network side device, where the first request information is used to request to release the connection between the terminal device and the LTE cell. In response to releasing the connection between the terminal device and the LTE cell, the terminal device enters a 4G idle mode, and displays the 5G network icon.
