A method and an apparatus for establishing a user plane bearer are provided. The method includes receiving a transport layer address supported by a serving gateway (SGW)/packet gateway (PGW) from a mobile management entity (MME), selecting, by a radio access network (RAN) entity, directly the appropriate transport layer address to establish the user plane bearer, or after receiving the transport layer address transmitted by the SGW/PGW, selecting, by the MME, the appropriate transport layer address to establish the user plane bearer, or reporting, by the MME, the obtained transport layer address used by the access entity to the SGW/PGW to establish the user plane bearer.

A solution for establishing a data traffic (e.g., PDU) session for a user equipment (UE) on a network (e.g., 5G cellular network) comprises receiving, by an access node (e.g., AMF), from a network repository (e.g., NRF), identification of a plurality of available session management nodes (e.g., SMFs), wherein the identification of the plurality of available session management nodes indicates whether each session management node supports a first traffic type or a second traffic type (e.g., IPv4 or (IPv6); determining, by the access node, a requested traffic type identified by the UE; determining a match between supported and requested traffic types; based at least on the match, selecting a session management node from the plurality of available session management nodes; and based at least on selecting the session management node, establishing the traffic session with the UE and the selected session management node.

A wireless communication terminal for wireless communication is disclosed. The wireless communication terminal includes: a transceiver; and a processor. The processor is configured to transmit a non-legacy physical layer frame including a legacy signaling field including information decodable by a legacy wireless communication terminal by using the transceiver.

Disclosed herein is a method, a wireless device and a session management node for IP version selection for a PDU session requested to be established by a WCD, that supports PDU sessions of both IPv4 and IPv6 and that is configured to operatively communicate via a RAN with a SM node in a core network lot, the method being performed by the WCD comprises: sending S110 a first PDU session request message towards the SM node requesting establishment of a first PDU session, which request message comprises IP-version information indicating that the IP version of the requested first PDU session should be any one of IPv4 or IPv6; and receiving S130, S140, in response to sending the first PDU session request message, a first response message, which first response message comprises WCD information indicating the IP-version (i.e. IPv4 or IPv6) that has been selected for the requested first PDU session.

A solution for establishing a data traffic (e.g., PDU) session for a user equipment (UE) on a network (e.g., 5G cellular network) comprises receiving, by a session management node, a request for the data traffic session for the UE; determining a requested traffic type for the data traffic session, wherein the requested traffic type comprises a first traffic type or a second traffic type; determining whether the session management node is connected to a first user plane function that can support the requested traffic type; based at least on determining that the first user plane function cannot support the requested traffic type, connecting, by the session management node, to a second user plane function that can support the requested traffic type; and based at least on connecting to the second user plane function, establishing the requested data traffic session for the UE using the second user plane function.

A mobile node includes a plurality of transceivers, has a network conforming to network-based mobility as its home link and performs position registration to a positional managing apparatus and performs position registration to the position managing apparatus through a foreign network by position registration conforming to host-based mobility. In mobile node and position managing apparatus, a plurality of routes passing through the home link and the foreign link are established. Accordingly, when the mobile node has the plurality of transceivers, it can simultaneously connect to the home link and the foreign link through respective transceivers, to perform communication.

A method and system for simplifying interactions of a Software Defined Network (SDN) controller including: receiving a network program to traverse a mobile node network including mobile nodes and ground nodes, wherein the ground nodes include an ingress node and an egress node; forecasting links, based on a temporal line-of-sight topology, of the mobile node network between the mobile nodes and the ground nodes; determining network program subfunctions that reflect an availability of the links for a time period; selecting, for the time period, a viable path including one or more of the network program subfunctions to traverse from the ingress node to the egress node; and communicating network traffic from the ingress node to the egress node using the viable path during the time period, wherein a portion of the viable path traverses one or more of the mobile nodes and the mobile nodes move along deterministic paths.

Method and apparatus for monitoring the status and location of personnel using a remote timer. In some embodiments, a method includes execution of a subject application (app) on a network accessible device. A countdown timer of a remote server is initiated to monitor a time interval, the remote server communicating with the network accessible device over a network. Geo positions of the network accessible device are monitored during the monitored time interval. The remote server sends a notification to a monitoring device responsive to at least one of the following events: the monitored time interval ends without the remote server receiving an authorized personal identification (PID) value; or the remote server receives an unauthorized PID value prior to the conclusion of the monitored time interval. In further embodiments, a notification is sent based on an out-of-bounds geo position of the network accessible device during the time interval.

A solution for establishing a data traffic (e.g., PDU) session for a user equipment (UE) on a network (e.g., 5G cellular network) comprises receiving, by a session management node, a request for the data traffic session for the UE; determining a requested traffic type for the data traffic session, wherein the requested traffic type comprises a first traffic type or a second traffic type; determining whether the session management node is connected to a first user plane function that can support the requested traffic type; based at least on determining that the first user plane function cannot support the requested traffic type, connecting, by the session management node, to a second user plane function that can support the requested traffic type; and based at least on connecting to the second user plane function, establishing the requested data traffic session for the UE using the second user plane function.
