  • Patent number: 10735888
    Abstract: A machine-to-machine (M2M) gateway (GW) includes reachability, addressing, and repository (RAR) capability. The GW maintains a local mapping table and local device application repository, performs data aggregation, address/name translation, provides event reporting and establishes GW reachability and wake-up time. The GW supports requests from M2M applications or other capabilities within the GW, and from a network and application (N&A) domain RAR. The GW may include an M2M device and M2M gateway management (MDGM) capability that receives management requests for an M2M device and functions as a network proxy. The MDGM accepts and processes requests from the N&A domain on behalf of the M2M device and performs management functions of the M2M device on behalf of the N&A domain. The MDGM may request the N&A domain for permission to interact with the M2M device, initiate an interaction for device management tasks with the M2M device, and report to the N&A domain.

  • Patent number: 9967016
    Abstract: A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted consecutively from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.

    Abstract: Systems, methods, and instrumentalities are disclosed that provide for a gateway outside of a network domain to provide services to a plurality of devices. For example, the gateway may act as a management entity or as a proxy for the network domain. As a management entity, the gateway may perform a security function relating to each of the plurality of devices. The gateway may perform the security function without the network domain participating or having knowledge of the particular devices. As a proxy for the network, the gateway may receive a command from the network domain to perform a security function relating to each of a plurality of devices. The network may know the identity of each of the plurality of devices. The gateway may perform the security function for each of the plurality of devices and aggregate related information before sending the information to the network domain.

  • Publication number: 20170353472
    Abstract: A user may access a subscription-based service via a system comprising one or more devices with one or more separate domains where each domain may be owned or controlled by one or more different local or remote owners. Each domain may have a different owner, and a remote owner offering a subscription-based service may have taken ownership of a domain, which may be referred to as a remote owner domain. Further, the user may have taken ownership of a domain, which may be referred to as a user domain. In order for the user to access the subscription-based service, registration and credential roll-out may be needed. An exemplary registration and credential roll-out process may comprise registration of the user, obtaining credentials from the remote owner and storing the credentials.

  • Patent number: 9781100
    Abstract: A constrained network entity may determine, via an authentication procedure with a core network entity, the trustworthiness of an endpoint attempting to establish a secure channel with the constrained network entity. The constrained network entity may receive a certificate from the endpoint attempting to establish the secure channel and the constrained network entity may send the certificate asserted by the endpoint to a core network entity for validation. The core network entity may receive the certificate during a key exchange with the constrained network entity and the core network entity may indicate to the constrained network entity the validity of the certificate. The constrained network entity may determine whether to establish the secure channel with the endpoint based on the validity of the certificate.

  • Patent number: 9762583
    Abstract: Methods and apparatus are disclosed to provide protection against Unsolicited Communication (UC) in a network, such as, without limitation, an Internet Protocol (IP) Multimedia Subsystem (IMS). A communication may originate from a sending device and may be intended for delivery to a receiving device. A network may determine authentication information associated with the sending device. The network may send the authentication information to a receiving entity to evaluate if the communication is unsolicited using the authentication information. If the communication is determined to be acceptable, a connection associated with the communication may be allowed.
