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.

Method and apparatus for managing cloud services using smart contracts and blockchains in a federation of cloud providers

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). A network slice is selected based on one or more criteria (step). A network slice attachment request is sent to a network node (step), for requesting attachment of the user equipment to the selected network slice of the mobile communications network.

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.

Systems and methods for routing traffic originating from a communication device

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.

Network partitions

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.

A VLC signal representing an alignment identifier is detected by cameras () of multiple user devices () filming a scene. Encoded video frames () from the user devices () 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 () from different user devices () to thereby achieve video frame synchronization of video data from multiple user devices () recording a scene. The embodiments thereby enable video frame synchronization without the need for accurate clock synchronization between the user devices () and a video synchronization system ().

VLC-based video frame synchronization

Example embodiments presented herein are directed towards a physical node, and corresponding methods therein, for providing authentication of a wireless device within a visiting wireless network while the wireless device is in a roaming state. The wireless device is registered to a home wireless network. The physical node further comprises a virtual representation of a functionality of at least one core network node controlled by the home wireless network. Thus, such authentication may be provided and control according to home network based procedures.

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

A method and message server () for routing a speech message, received (2:1) from a user equipment () of a sending user, to at least one recipient () in a communication network. After obtaining (2:2) a text version created by speech recognition () of the received speech message, the at least one recipient is identified (2:3) by the message server based on the obtained text version, and the speech message is then routed (2:5) to the identified at least one recipient.

Method and message server for routing a speech message

A method and apparatus for transferring a message from a wireless communication device to another communication device. A communications device generates a message using the wireless communication device. The wireless communication device determines a geographical location and an orientation of the wireless communication device. A geographical region is determined using the geographical location and orientation, and a remote server determines the presence of an entity associated with the other communication device in the selected geographical region. The message is then transferred to the other communication device.

Transferring messages in a communications network

A method of prioritizing actions at a gateway () to a bearer network (), the gateway comprising a Media Gateway () which is responsible for establishing call connections over said bearer network () and a Media Gateway Controller () coupled to the Media Gateway. A signalling message is received at the Media Gateway Controller (), which determines the priority of the message. The signalling message is converted into a Media Gateway Control Protocol (MGCP) message including a parameter indicating the priority of the associated signalling message. The MGCP is then transferred to the Media Gateway () which acts upon the message in accordance with the indicated priority.
