  • Publication number: 20200053686
    Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using control plane (CP) optimization with optional use of Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using CP optimization. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling association with a RAN node to send the event report using CP optimization and optionally using EDT. The RAN node may then release the signaling association after the LS returns a single response to the UE.

  • Publication number: 20200045666
    Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using EDT. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling connection with a RAN node but not with a core network to send the event report using EDT. The RAN node may then release the signaling connection, either immediately or after the LS returns a single response to the UE.

  • Patent number: 10470218
    Abstract: An example method is provided in one example embodiment and may include determining that a user equipment (UE) is approximately stationary for a threshold period of time within a particular geographic area based, at least in part, on a radio access network (RAN) node to which the UE is attached; notifying the UE that the UE has been associated with the particular geographic area; and transitioning the UE into an idle mode from an active mode, wherein the transitioning is performed without notifying a core network that the UE has transitioned to the idle mode. Determining that the UE is approximately stationary can include monitoring mobility signaling from the UE and comparing an amount of time that the UE has been attached to the RAN node with a threshold period of time. The core network can be notified when the UE moves out of the particular geographic area.

  • Publication number: 20190132768
    Abstract: A method is provided in one example embodiment and may include receiving congestion information for an environment in which a user equipment (UE) is operating; receiving a first request to deliver content to the UE; determining that the environment in which the UE is operating is experiencing congestion based, at least in part, on the congestion information; determining a re-try interval based, at least in part, on the congestion information; and deferring delivery of the content to the UE until the re-try interval has expired. In one example embodiment, the method can include provisioning one or more policy rules for a service data flow associated with the content and communicating the indication indicating that delivery of the content has been deferred to a charging system to set charging information for at least one of a user associated with the UE or a provider of the content.

  • Publication number: 20190124561
    Abstract: Aspects of the present disclosure relate to a mechanism to enable interworking between fifth generation system (5GS) network slicing and evolved packet core (EPC) connectivity. In an example, techniques are provided for existing packet data unit (PDU) sessions that provide connectivity to a network slice from a set of network slices. Connectivity to the network slice is in response to a user equipment (UE), that uses network slices, moving between a 5G network and a 4G network. The existing PDU sessions are connected to a dedicated EPC core network that supports the same services provided by the network slice.

  • Publication number: 20190090298
    Abstract: A core network receives data from at least one of an AF, a DN, or a UE. A UPF having small data capability processes the data for transport with a low overhead and without initiating a bearer set up protocol. The data may be transported between the UE and the UPF as an RRC payload over a NAS protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as an RRC payload. The data may be received as uplink data from a UE, e.g., in an RRC payload. The UPF may process the RRC payload to obtain the data and may transport the data to the AF or DN. The UPF may perform IP header compression, data encryption, and/or buffering of data for a UE in an idle mode.

  • Publication number: 20190090123
    Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.

  • Publication number: 20180359786
    Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.

  • Patent number: 9661529
    Abstract: The present disclosure is directed at systems, methods and media for mitigating congestion for roamers in a wireless access network. In some embodiments, Radio Access Network (RAN) congestion information is reported from a base station to a RAN Congestion Awareness Function (RCAF) of a visited network. The RCAF can mitigate congestion by controlling Quality of Service (QoS) parameters for roaming User Equipment (UE) in a congested cell. The RCAF can further communicate with the Mobility Management Entity (MME) of the visited cell and the Policy Charging and Rules Function (PCRF) of the UE's home network. The RCAF can relieve congestion for roamers without informing the home network of the congestion at the cell.
