  • Publication number: 20210021376
    Abstract: Techniques are described to provide ultra-reliability for cellular vehicle-to-everything (C-V2X) PC5 communications, including Network Assisted mode and Autonomous mode communications. In one example, a method includes receiving, by a radio unit of a system, a communication from a user equipment, such as a V2X-UE, wherein the communication comprises a data packet, a Layer 2 destination identifier, and an indication that the data packet is associated with a transmission type; determining whether transmission for the data packet is allowed for the transmission type; based on determining that transmission for the data packet is allowed for the transmission type, communicating a response to the UE, wherein the response provides a confirmation to the UE that the data packet was received by the radio unit and that the transmission type can be performed by the radio unit; and transmitting, by the radio unit, the data packet to one or more other UEs.

  • Publication number: 20210022103
    Abstract: Techniques are described to provide a network location service for a user equipment (UE) when the UE is not served by a 3GPP radio; thereby enabling radio resource selection by the UE for Autonomous PC5 based communications. In one example, a method includes receiving, by a mobility element of a network, an attach request from a UE, wherein the attach request indicates an attach type associated with a network location service. The method may further include communicating, based on the attach type being associated with the network location service, an attach accept to the UE to trigger a location request for the UE, wherein the attach accept is communicated to the UE without the mobility element authenticating the UE; and communicating location information to the UE based on the location request.

  • Patent number: 10893554
    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.

  • Patent number: 10887799
    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.

  • Patent number: 10880748
    Abstract: Techniques are described to provide open access in a neutral host environment. In one example, a method includes obtaining, by a mobility management node of a neutral host network, a network connectivity request from a user equipment, wherein the network connectivity request comprises an indication of a preferred service provider to which the user equipment is to be connected; determining, by the mobility management node, that the preferred service provider provides non-subscription-based network connectivity for the neutral host network; based on determining that the preferred service provider provides non-subscription-based network connectivity for the neutral host network, establishing secure communications for the user equipment, wherein the secure communications are established for the user equipment without authenticating an identity of user equipment; and providing network connectivity between the user equipment and the preferred service provider upon establishing the secure communications.

  • Patent number: 10880862
    Abstract: Paging for converged enterprise private Long-term Evolution (LTE) radio service and Wi-Fi access deployments may be provided. First, a notification in response to a User Equipment (UE) device being determined to be in an idle state may be received at a Wireless Local Area Network (WLAN) controller. A Citizens Broadband Radio Service (CBRS) Access Point (AP) to page in order to place the UE in a connected state may then be determined. Next, a paging request may be sent to the determined CBRS AP.

  • Publication number: 20200342766
    Abstract: Techniques are described herein for dynamic platoon management. The techniques may include obtaining dynamic location data of a vehicle, where the dynamic location data indicates a current or predicted location of the vehicle. Based on the dynamic location data, a platoon of vehicles that is optimal for the vehicle to join may be identified. The vehicle may be dynamically joined to the platoon.

  • Patent number: 10694560
    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.

  • Patent number: 10588052
    Abstract: A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.
