Abstract: Some aspects of the disclosure provide various methods, apparatuses and computer-readable medium configured for wireless communication. A method operable at a user equipment (UE) may include transmitting a connection request message configured to request initial connection with a radio access network (RAN) node. The connection request message may include information configured to indicate a service profile of the UE. A method operable at the RAN node may include receiving the connection request message from the UE. The connection request message may include information configured to indicate the service profile of the UE. A method operable at a serving node may include receiving a connection request message from the RAN node. The connection request message may be configured to establish communication with the UE and may include a service profile corresponding to the UE.

Abstract: Methods, systems, and devices for wireless communication are described. Relocation of a user plane may be minimized through the exchange of communication session information between network nodes. For example, a connectivity session manager and an access and mobility manager may exchange information associated with a user equipment (UE) communication session to prevent unnecessary reestablishment of an existing communication session. In such cases, the access and mobility manager may receive a session management request from a UE and send a request including the session management request to the connectivity session manager. Based on the received message, the connectivity session manager may identify a continuity mode, select a user plane anchor for the communication session, and send a response message to the access and mobility manager. In some examples, the connectivity session manager and the access and mobility manager may exchange session area codes associated with the location of the UE.

Abstract: The present disclosure provides techniques that may be applied, for example, in a multi-slice network for maintaining privacy when attempting to access the network. An exemplary method generally includes transmitting a registration request message to a serving network to register with the serving network; receiving a first confirmation message indicating a secure connection with the serving network has been established; transmitting, after receiving the first confirmation message, a secure message to the serving network comprising an indication of at least one configured network slice that the UE wants to communicate over, wherein the at least one configured network slice is associated with a privacy flag that is set; and receiving a second confirmation message from the serving network indicating that the UE is permitted to communicate over the at least one configured network slice.

Abstract: A gateway device detects a trigger associated with a device and, in response, identifies an application service associated with the device, obtains a traffic network policy associated with the application service, and obtains a network access token based on the traffic network policy. The network access token facilitates validating and/or mapping a downlink data packet obtained at the gateway device in user-plane traffic that is destined for the device. The network access token is sent to an entity in control-plane signaling. Subsequently, the gateway device obtains a downlink data packet including the network access token. The gateway device verifies the network access token and/or maps the downlink data packet to the device using data obtained from the network access token. The network access token may be removed from the downlink data packet before the downlink data packet is sent to the device according to the mapping.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device transmits an indication of whether the device should be paged over a 3GPP access when a core network has data ready to transmit for PDU sessions over a non-3GPP access. A session management function (SMF) of the core network receives a data notification indicating that the core network has data ready to transmit to the wireless device for a PDU session over the non-3GPP access. The SMF determines whether to transmit a paging request to an access and mobility management function (AMF) of the core network based on a paging state of the SMG, a paging state of the wireless device, or a connection management idleness state of the wireless device. The AMF determines whether to transmit a paging message to the wireless device.

Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.

In some examples, a handover from a legacy access network to a next generation access network may be performed via a next generation core network. A handover request received at a next generation core network serving node may include an identifier of a next generation target cell. The next generation core network serving node may identify another next generation core network serving node to which the handover may be forwarded based on the target cell identifier or may select the next generation access network based on the target cell identifier. The next generation core network serving node may then communicate with the next generation access network to complete the handover.
