Abstract: Dynamic roaming partner prioritization based on service quality feedback may be provided. First, a server associated with an enterprise may receive performance data and location data for each of a plurality of service provider networks from a plurality of end use devices associated with the enterprise. Next, the server may assign a ranking to a plurality of service providers by location based upon information. The information may comprise the received performance data and the location data corresponding to each of the plurality of service provider networks. The server may then push the ranking to a first end use device.

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: In one embodiment, a method is performed. An interworking module of a wireless local access network (LAN) controller may receive a non-access stratum (NAS) message from an access point (AP) device using a control and provisioning of wireless access protocols (CAPWAP) tunnel. The NAS message may be translated to a WiFi service layer message. The WiFi service layer message may be sent to a wireless control plane module of the wireless LAN controller.

Abstract: In one embodiment, a system, apparatus, and method are described for requesting access authorization from an access network access point (AP) via an access network interface, generating at a processor a public-private key pair to be used to generate a cryptographically generated address (CGA) upon receiving the access authorization, sending a secure neighbor discovery (SeND)—neighbor solicitation (NS) to the AP via the access network interface after the public-private key pair has been generated, receiving a signed user location information (ULI) from the AP in response to the SeND-NS, and sending the signed ULI to one of a 3GPP mobility controller or an emergency service via a 3GPP network interface. Related systems, apparatuses, and methods are also described.

Abstract: In one embodiment, a supervisory service receives a registration message broadcast by a first vehicle and captured by a RSU in the network of RSUs. The supervisory service registers the first vehicle by validating a signature of the registration message without registering a media access control (MAC) address of the first vehicle and without causing to send a registration response to the first vehicle. The supervisory service receives a message broadcast by a second vehicle addressed to the first vehicle and captured by at least one RSU in the network of RSUs. The supervisory service selects one or more RSUs in the network of RSUs to re-broadcast the message. The supervisory service controls the one or more RSUs to re-broadcast the message.

Abstract: Embodiments are directed to a virtual mobility anchor network element to receive, from a packet gateway (PGW) node, a request for an internet protocol (IP) address for a mobile device, establish an IP address for the mobile device; and provide the IP address to the PGW node in response to the request for the IP address for the mobile device. The virtual mobility anchor network element is configured to receive IP traffic from a network location; determine a target destination for the IP traffic based on a destination IP address, the destination IP address comprising the second IP address; and forward the IP traffic to the PGW node associated with the destination IP address. The virtual mobility anchor network element is also configured to receive IP traffic from the PGW node; determine a target destination for the IP traffic; and route the IP traffic to the target destination.

Abstract: An example method is provided in one example embodiment and may include receiving a power saving mode (PSM) request by a long range radio, wherein the PSM request comprises an identification of at least one receive window to disable for the long range radio for a plurality of uplink transmissions and an identification of a duration for which the at least one receive window is to be disabled for the plurality of uplink transmissions; and transmitting the plurality of uplink transmissions by the long range radio, wherein the at least one receive window is disabled following each uplink transmission of the plurality of uplink transmissions by the long range radio for the duration identified in the PSM request.

Abstract: An example apparatus for discovery and acquisition of a control channel using guard bands is provided and includes a processor; and a memory in communication with the memory. The processor configured is to determine that a whitespace map is unavailable for communication between a first device and a second device; determine that a guard band is to be used for a control channel between the first device and the second device; send a first message to the second device including an indication to the second device that the second device is use a guard band to maintain communication with the first device; and send a second message to the second device including control channel tuning information associated with the guard band.

Abstract: A local mobility anchor (LMA) connected to a network receives session requests sent by first and second gateways on behalf of a mobile node seeking to establish a mobility session with the network. The LMA selects, based on a gateway selection criterion, either a first or a second gateway as active for actively handling the mobility session and the other gateway as standby. The LMA commands the active gateway to actively handle the mobility session and to configure the mobile node to use the active gateway for the mobility session. The LMA commands the standby gateway to not configure the mobile node and to operate in active standby to handle a failover of the mobility session from the primary gateway. The LMA establishes with the active gateway a first IP tunnel to be used for the mobility session.
