Abstract: A method for updating access technology information for a Multi-Access (MA) Protocol Data Unit (PDU) session is provided. A User Equipment (UE) establishes an MA PDU session with a mobile communication network over a 3rd Generation Partnership Project (3GPP) access and a non-3GPP access. The UE provides first access technology information indicating to the mobile communication network that the UE is using one of the 3GPP access and the non-3GPP access to get an Internet Protocol (IP) connectivity. The UE detects that the IP connectivity over the one of the 3GPP access and the non-3GPP access is deactivated. The UE provides second access technology information indicating to the mobile communication network that the UE is using the other of the 3GPP access and the non-3GPP access to get another IP connectivity.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a mobile communication network. The controller determines whether the mobile communication network supports IMS services. The controller establishes a Packet Data Network (PDN) connection or a Protocol Data Unit (PDU) session with the mobile communication network for the IMS services via the wireless transceiver in response to the mobile communication network supporting the IMS services. The controller sends application data on the PDN connection or PDU session via the wireless transceiver.
