Abstract: Supporting Multipath Transmission Control Protocol (MPTCP) subflows using multipath links, and more specifically supporting MPTCP subflows using Wi-Fi Multi-Link Operation (MLO) or cellular multi-link support may be provided. A multipath link may be established between an Access Point (AP) and a station (STA). The STA may mark the multipath link as Multipath Transmission Control Protocol (MPTCP) capable. Next, a request for an addition of a MPTCP subflow may be received. In response to receiving the request, the MPTCP subflow may be bound to the multipath link, and data from the MPTCP subflow may be sent over the multipath link.

Abstract: Methods are provided which indicate availability of the same service on a different access network. In these methods, the network controller generates an identifier for each of one or more services provided by a wireless local access network (WLAN). The identifier is associated with a particular service which is also provided by a private radio network. The network controller provides to an access point the identifier to be broadcast to one or more user devices of the WLAN to connect to the particular service via the private radio network. A mobility management entity receives a request from a user device to connect to the private network, where the request includes an identifier associated with a particular service provided to the user device in the WLAN and based on the identifier, the mobility management entity enables the particular service to be provided to the user device via the private radio network.

Abstract: Adaptive transition between an inactive state and an idle state may be provided. An end node device may be configured with an end node device upper threshold. Next, it may be determined that that client devices are inactive preferred. Then the client devices determined to be inactive preferred may be assigned to a Radio Resource Control (RRC) inactive state and to the end node device. One or more of the client devices previously assigned to the RRC inactive state may be assigned to an RRC idle state and to an intermediate device until a number of the client devices assigned to the end node device is less than or equal to the end node device upper threshold.

Abstract: A Radio Access Network (RAN) element provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The RAN element determines that the RAN element is connected to at least one gateway that provides public internet access, and broadcasts an internet indication. The RAN element determines that the UE has requested public internet access via the RAN element and provides the UE with public internet access.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.

Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.

Abstract: Methods for extending cell broadcast notifications to various access technologies and enterprise communication infrastructure. A method includes obtaining, by a controller, a cellular broadcast message of a public warning system and identifying, by the controller, at least one network entity, from among a plurality of network entities operating in a private radio network, based on the at least one network entity being within a location area specified in the cellular broadcast message. The method further includes providing, by the controller to the at least one network entity, the cellular broadcast message.

Abstract: This disclosure describes techniques for authentication related to verification of identity for network access. The techniques may include sending a challenge associated with authentication to a network to a mobile device. In response to sending the challenge, the techniques may include receiving a challenge response from the mobile device. The challenge response may include biometric credential information associated with a user of the mobile device. The challenge response may also include an indication of an authorization assertion associated with the authentication to the network. In some examples, the techniques may include tailoring access to the network for the mobile device based on the biometric credential information.

Abstract: Presented herein are techniques to facilitate visited network selection by a user equipment (UE) based on slice considerations. In one example, a method may include requesting, by a UE that is roaming among a plurality of visited mobile networks, registration for a network connection associated with a slice type; obtaining, by the UE from home mobile network for the UE, a priority for each of the plurality of visited mobile networks and an indication of one or more slice types provided by each of the plurality of visited mobile networks; selecting, by the UE, a highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type; and establishing, by the UE, the network connection with the highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type.

Abstract: In one illustrative example, a user plane function (UPF) configured for use in a private 5G network of an enterprise may receive, from a user device, a domain name system (DNS) query associated with an application; send, to a DNS server, one or more corresponding DNS queries based on the DNS query; receive, from the DNS server, one or more DNS query responses which include an IP address and metadata including an application identifier for the application; and send, to a control plane function, a message for reporting which includes the application identifier. In response, a dedicated Quality of Service (QoS) Flow may be created for traffic for the application according to a selected QoS policy associated with the application identifier. For obtaining the metadata, the UPF may interact with a DNS server configured with Extension mechanisms for DNS (EDNS) or a DNS as Authoritative Source (DNS-AS) mechanism.
