  • Publication number: 20220141719
    Abstract: Some embodiments of this disclosure include apparatuses and methods for managing a fast return of a user equipment (UE) to 5G systems (5GS) after handover to Evolved Packet System (EPS) due to EPS fallback from 5GS. The method can include at least generating a handover request including an indication indicating a handover reason of no presence of quality of service (QoS) flow for a voice signal to the UE; receiving a handover command generated by an access and mobility management function (AMF) to transfer the UE from the 5GS to the EPS based on the handover request; transmitting the handover command to the UE for the UE to establish a connection with the EPS; and after the flow of the voice signal has terminated, reestablishing a connection with the UE to reconnect the UE to the 5GS, wherein the connection with the BS is re-established based on a target ID of the BS.

  • Publication number: 20220095260
    Abstract: Some embodiments of this disclosure include apparatuses and methods for facilitating vehicle-to-everything (V2X) communications with user equipment (UE). In some embodiments, processing circuitry a communication network system may receive a registration request message from a UE indicating a V2X Radio Access Technology (RAT) configuration supported by the UE. The processing circuitry may retrieve authorization information from a Unified Data Management (UDM) repository and apply a policy control function (PCF) to the authorization information and the V2X RAT configuration specified by the UE to determine whether the UE has been authorized to communicate using the indicated V2X RAT configuration. In response to determining that the UE is authorized to communicate using the indicated V2X RAT configuration, the processing circuitry may transmit V2X service authorization parameters corresponding to the indicated V2X RAT configuration to a Radio Access Network (RAN) base station servicing the UE.

  • Publication number: 20220007161
    Abstract: Systems and methods provide solutions for provisioning vehicle-to-everything (V2X) policy and parameters to a user equipment (UE). A UE may generate a registration request to register with a wireless network. The registration request may include a first indication of a V2X policy provisioning request. The UE processes a message from a policy control function (PCF) including either a current V2X policy and corresponding parameters or a second indication that the PCF does not support V2X provisioning.

  • Publication number: 20210314899
    Abstract: Systems, apparatuses, methods, and computer-readable media are provided for indicating local area data network (LADN) data network names (DNNs). In embodiments, a user equipment (UE) provides a list of configured LADN DNNs in a registration request message during a registration procedure. An Access and Mobility Management Function (AMF) determines LADN information for the UE by looking into configured LADN DNNs in the AMF and/or retrieved LADN authorization/subscription information. The LADN information includes a list of LADN DNNs and corresponding LADN service area(s) that the UE can use, including LADN DNNs that the UE can use in a current registration area. The AMF sends the LADN information to the UE in a registration accept message. Other embodiments may be described and/or claimed.

  • Patent number: 11122505
    Abstract: An apparatus for use in a serving gateway user plane (SGW-U) of an evolved packet core (EPC) of a wireless communication network is disclosed. The apparatus comprises one or more processors configured to process a downlink (DL) data signal comprising a DL data packet for a user equipment (UE) in the network, buffer the DL data packet in the DL data signal and identify a serving gateway control plane (SGW-C) associated with the SGW-U that serves the UE, when the UE is in idle mode. The one or more processors is further configured to provide an SGW-U DL data notification message to the SGW-C, generated selectively based on a priority of the received DL data signal, in order to inform the SGW-C about the availability of DL data for the UE.

  • Patent number: 11076318
    Abstract: One or more techniques of authorizing vehicle-to-everything (V2X) in a wireless network are set forth herein. In one example, during an initial registration procedure or an attach procedure, a UE includes its fifth generation (5G) V2X capability in a Non Access Stratum (NAS) message to a Mobility Management Entity (MME) or an Access and Mobility Management Function (AMF). The MME or the AMF stores this information and determines whether the UE is capable of or authorized to use V2X communication subscription information received from a Home Subscriber Server (HSS) or a Unified Data Management (UDM). If the UE is authorized, the MME or the AMF includes the V2X services authorized in a message from the MME or the AMF to an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) or a Next Generation Radio Access Network (NG RAN).

  • Patent number: 10986539
    Abstract: Embodiments of Vehicle-to-everything (V2X) communications authentication are described. In some embodiments, a user equipment (UE) configured V2X communication and configured to operate within a fifth-generation system (5GS) and/or a combined 5GS and fourth-generation system (4GS) can encode a V2X capability indication in a request message for transmission to a network entity, such as a Access and Mobility Management Function (AMF). The V2X capability indication can indicate a capability of the UE for V2X communication over a PC5 reference point, and the request message can further include an indication of a Radio Access Technology (RAT). In some embodiments, the AMF can determine whether the UE is authorized to use the V2X communications over the PC5 reference point, and whether the UE is authorized to use the RAT indicated in the request message. Accordingly, the AMF can transmit a V2X services authorization to a next generation radio access network (NG-RAN).

  • Publication number: 20210068200
    Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB) and methods for communication are generally described herein. An UE may be configurable to operate as an eRelay UE. The eRelay UE may be configured to operate as a relay between an eNB and an eRemote UE. The eRelay UE may receive, from the eRemote UE, a message that includes an identifier of the eRemote UE for paging of the eRemote UE. The eRelay UE may determine whether a first paging message from the eNB includes the identifier of the eRemote UE. If it is determined that the first paging message includes the identifier of the eRemote UE, the eRelay UE may transmit, to the eRemote UE, a second paging message to page the eRemote UE. The second paging message includes the identifier of the eRemote UE.

  • Publication number: 20210014765
    Abstract: This disclosure describes systems, methods, and devices related to data forwarding tunnel establishment between two user plane functions in fifth generation (5G). A device may determine an association of an access and mobility management function (AMF) with a first radio access network (RAN). The device may identify a handover request message received from the first RAN via the AMF. The device may identify a request to establish an indirect data forwarding associated with the handover, wherein the request is received from the first RAN via the AMF. The device may cause to send a response addressed to the AMF indicating that the indirect data forwarding is established.
