  • Publication number: 20220053332
    Abstract: Systems and methods of providing secondary authentication credentials for an external network are described. The credentials are provided from the UE to the GGSN via the SGSN during establishment of a PDN connection for the UE in a NAS message. The SGSN receives an Activate PDP Context Request from the UE and sends to the GGSN a Create PDP Context Request. The Requests include a PCO IE with the credentials. The GGSN determines a RADIUS and/or DHCP server to be used for IP address allocation, a protocol to be used with the server, and security features to use to dialogue with the server. The GGSN obtains the IP address from the server and provides the IP address to the UE via the SGSN via Create PDP Context Response.

  • Patent number: 11251932
    Abstract: Embodiments of the present disclosure describe techniques and configurations for triggering transmission of data payloads in a wireless communication network. An apparatus may include one or more computer-readable media having instructions and one or more processors coupled with the one or more computer-readable media and configured to execute the instructions to implement an interworking function (IWF) to receive, from a Machine Type Communication (MTC) server, a trigger request to trigger sending of a data payload over a wireless communication network, the data payload being smaller than a preconfigured threshold, and send, in response to the trigger request over a reference point to a module including a Mobility Management Entity (MME) or a Serving GPRS (General Packet Radio Service) Support Node (SGSN), a trigger notification to trigger sending of the data payload over the wireless communication network.

  • Publication number: 20220022105
    Abstract: Systems and methods of providing 5G access for a UE are generally described. The UE is simultaneously connected via dual radio operation to a legacy and 5G access system. The UE mobility management states for the access systems are independent of each other. The EPC and 5G CN share an HSS and may share a IP anchor. When handover occurs between access systems, the IP address is retained and the IP anchor used when the UE transmits an Attach Request having a Handover Attach Request Type and otherwise a new IP address is provided and the HSS but not the IP anchor is common between the access systems. The 5G eNB to which the UE is connected is standalone and connected to the 5G CN or dual mode and connected with an EPC via an LTE anchor in addition to the 5G CN.

  • Patent number: 11108754
    Abstract: Device to device (D2D) communication can be performed with packet data convergence protocol (PDCP) based encapsulation without internet protocol (IP) addressing. The non-IP D2D PDCP-encapsulated communication can further include two forms of secure data transfer. A first non-IP D2D PDCP-encapsulated communication can be a negotiated non-IP D2D PDCP-encapsulated communication. A second non-IP D2D PDCP-encapsulated communication can be a non-negotiated non-IP D2D communication. The non-negotiated non-IP D2D PDCP-encapsulated communication can include a common key management server (KMS) version and a distributed KMS version. The encapsulated communication can be used with various protocols, including a PC5 protocol (such as the PC5 Signaling Protocol) and wireless access in vehicular environments (WAVE) protocols.

  • Publication number: 20210243775
    Abstract: An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).

  • Patent number: 10972235
    Abstract: Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

  • Patent number: 10951480
    Abstract: Technology for a virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate instantiation of a virtualized network function (VNF) instance is disclosed. The VNFM can receive a request to instantiate a new VNF instance from a network manager (NM) via a network function virtualization (NFV) orchestrator (NFVO), the request including VNF instantiation information. The VNFM can send a request to a virtualized infrastructure manager (VIM) for allocating virtual resources for the new VNF instance based on the VNF instantiation information. The VNFM can receive an acknowledgement from the VIM after successful allocation of the virtualized resources for the new VNF instance. The VNFM can instantiate the new VNF instance and send an acknowledgement of the new VNF instance to the NFVO, wherein the new VNF instance is operable to ease congestion at an overloaded non-virtualized network element in the mixed wireless network.

  • Patent number: 10932158
    Abstract: Some demonstrative embodiments include devices, systems and methods of offloading traffic of a Secondary Cell Group (SCG). For example, some embodiments may include identifying a SCG bearer that is offloadable to the Internet via a Network Address Translation (NAT) gateway, based on offloading information received from a Master Evolved Node B (eNB) (MeNB); and offloading uplink Internet Protocol (IP) packets of the SCG bearer to the Internet via the NAT gateway, if the SCG bearer is indicated to be offloadable.

  • Publication number: 20210050907
    Abstract: A relay device assists in enabling lawful intercept (LI) by reporting, to a LI entity associated with the cellular network, authenticated identities of remote UEs (such as remote UEs connected via proximity services) and identification information that may allow the LI entity to monitor traffic (and/or control statistics related to the traffic) associated with the remote UEs. The authentication of the remote UEs may be performed using a technique that does not require involvement of the cellular network.

    Abstract: Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

  • Patent number: 10848957
    Abstract: This document discusses, among other things, a Cellular Internet-of-Things (CIoT) network architecture to enable communication between an apparatus of a CIoT User Equipment (UE) and a network through a CIoT enhanced Node B (eNB) according to a lightweight Non-Access Stratum (NAS) protocol. An apparatus of a CIoT eNB can process data for communication between the CIoT UE and the network. The lightweight NAS protocol supports a reduced set of NAS messages for communication between, for example, the CIoT UE and the CIoT eNB, such as using a modified NAS message, or one or more new messages.
