  • Publication number: 20210136666
    Abstract: Systems and methods for providing access prioritization to a private Long Term Evolution (LTE) network operating in a Citizens Broadband Radio Service (CBRS) spectrum include receiving, at a network device of the private Long Term Evolution (LTE) network, a functional group associated with a user equipment (UE) and a traffic load of a cell of the private LTE network associated with the UE. An access priority associated with the functional group and the traffic load is determined and provided to a CBRS access point (AP) which controls access to the cell. The access priority indicates to the CBRS AP a priority with which the UE is allowed to access the cell and can include a high priority, a low priority, or no access indication.

  • Patent number: 10986605
    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.

  • Publication number: 20210058988
    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.

  • Publication number: 20210051528
    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.

  • Publication number: 20210045013
    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.

  • 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.
