    摘要： A network component of a radio access network (RAN) is configured to provide network slice information to a user equipment (UE). The network component receives an indication that a user equipment (UE) is requesting to access a network slice, determines a frequency associated with the network slice, identifies a cell within the RAN that operates on the frequency associated the network slice and transmits a message to the UE, wherein the message indicates the cell within the RAN that operates on the frequency associated with the network slice.

    摘要： Apparatus and methods to support IP flow mobility (IFOM) via multiple wireless accesses in a wireless device are disclosed. The wireless device initiates network-based IFOM (NB-IFOM) to establish and manage IP flows. Support for NB-IFOM is negotiated during initial attach procedures to either or both wireless accesses and by using packet data network (PDN) connectivity procedures. The wireless device sends routing rules including priorities to apply to both existing and future IP flows or to future IP flows only. The wireless device requests to move IP flows from a source access to a target access. When a new wireless access is added to an existing PDN connection, an identical IP address for the wireless device is allocated as used for the existing PDN connection. The network establishes a GPRS tunneling protocol (GTP) tunnel for the new wireless access while maintaining a previously established GTP tunnel for the existing wireless access.

    摘要： An access and mobility management function (AMF) of a 5G core network configured to transmit a network function registration request to a network resource function (NRF), receiving a response to the network function registration request from the NRF, transmit a network function discovery request to the NRF, the network function discovery request including one or more single network slice selection assistance information (S-NSSAI) and an indication that the discovery request is for a network slice admission control function (NSACF) and receive a network function discovery response from the NRF, wherein the network function discovery response includes a NSACF address.

    摘要： Embodiments of a Multicast Broadcast Service (MBS) for 5G New Radio (NR). In one aspect, a user equipment (UE) receives first data from a network via unicast, receives first information from the network, the first information indicating the availability of a multicast service, transmits second information to the network and receives second data from the network via multicast in response to transmitting the second information to the network. In another aspect, a UE receives first information from the network, the first information indicating the availability of a multicast service, receives first data from the network via a multicast session and receives second data from the network via a unicast packet data unit (PDU) session.
