Abstract: A first data center receives a request, from a tenant, to access a first service. Responsive to determining that the tenant is not associated with a delegation contract, the first data center records a delegation contract for the tenant. A second data center receives a request, from the tenant, to access a second service, where the second data center is physically separate from the first data center. Responsive to determining that the tenant is associated with the delegation contract recorded in the blockchain database, the second data center causes an update of the delegation contract in the blockchain database; causes the second service to provide access to the tenant; transmits, to the tenant, a confirmation that the second service can be accessed, and transmits an update to the first data center indicating that the delegation contract has been updated to include a second service offer.

Abstract: A method in a user equipment for attaching the user equipment to a mobile communications network comprises receiving a list of network slice identities, wherein a network slice identity identifies a portion of the mobile communications network that serves as a logical network to a set of user equipment (step 201). A network slice is selected based on one or more criteria (step 203). A network slice attachment request is sent to a network node (step 205), for requesting attachment of the user equipment to the selected network slice of the mobile communications network.

Abstract: Using an authentication server to program network elements, such as a network node, in accordance with software-defined networking techniques in order to establish a traffic flow rule for a communication device or user of the communication device. After successfully authenticating a communication device or user, the authentication server and/or network node may use an identifier received at the authentication server in connection with the authentication procedure in order to obtain a traffic flow rule for the communication device. The traffic flow rule may be established at the network node or forwarded to a second network node configured to receive network packets from the communication device. The first identifier may be any one of a user identifier identifying a user, an application identifier identifying an application, and a device identifier unique to the communication device.

Abstract: In response to a transition from a previous operational state to a current operational state of a given network partition of a plurality of network partitions of a core of a cellular network, a respective entry of a registry of the plurality of network partitions is updated. Network partition selection for a terminal is effected by participating in a communication of at least one selection control message corresponding to at least one entry of the registry.

Abstract: A method for selecting a media processing unit performed in a network node of a distributed cloud. The distributed cloud comprises two or more media processing units that handle media processing required by a media service. The method includes receiving, from a communication device, a request for the media service and obtaining, for each media processing unit, at least one configurable parameter value of a parameter relating to handling of the media service. The method also includes selecting, based on the at least one parameter value, a media processing unit for processing the requested media service for the communication device.

Abstract: A tenant management system and method operative in a cloud-based database environment. A distributed blockchain ledger is provided for holding tenant records embodied in smart contracts, the consistency of which is maintained by a consensus protocol between multiple chain servers processing requests from leaf servers for tenant authorization and charging. The tenant records contain the bytecode for the tenant management contracts, the tenant's credit, and other state associated with the contract such as the services the tenant is authorized to access.

Abstract: Embodiments are directed to using an authentication server (140) to program and reprogram network elements, such as a network node (150), in accordance with software-defined networking techniques in order to establish a traffic flow rule for a communication device (110) or user of the communication device (110). After successfully authenticating a communication device (110) or user, the authentication server (140) and/or network node (150) may use an identifier received at the authentication server (140) in connection with the authentication procedure in order to obtain a traffic flow rule for the communication device (110). The traffic flow rule may be established at the network node (140) or forwarded to a second network node configured to receive network packets from the communication device (110). The first identifier may be any one of a user identifier identifying a user, an application identifier identifying an application, and a device identifier unique to the communication device (110).

Abstract: A VLC signal representing an alignment identifier is detected by cameras (4) of multiple user devices (1, 2, 3) filming a scene. Encoded video frames (91, 92, 93) from the user devices (1, 2, 3) are decoded and light patterns representing the captured VLC signal are identified in at least some of the video frames following decoding. The light patterns are decoded into alignment identifiers that are used in order to time align video frames (91, 92, 93) from different user devices (1, 2, 3) to thereby achieve video frame synchronization of video data from multiple user devices (1, 2, 3) recording a scene. The embodiments thereby enable video frame synchronization without the need for accurate clock synchronization between the user devices (1, 2, 3) and a video synchronization system (10).

Abstract: Methods and nodes for enabling and producing input generated by speech of a user, to an application. When the application has been activated (2:1), an application node (200) detects (2:2) a current context of the user and selects (2:3), from a set of predefined contexts (204a), a predefined context that matches the detected current context. The application node (200) then provides (2:4) keywords associated with the selected predefined context to a speech recognition node (202). When receiving (2:5) speech from the user, the speech recognition node (202) is able to recognize (2:6) any of the keyword in the speech. The recognized keyword is then used (2:7) as input to the application.
