A method and a first agent controlling computing resources in a first edge cloud, for supporting a machine learning operation. When detecting that additional computing resources outside the first edge cloud are needed for the machine learning operation, the first agent obtains said additional computing resources from a second edge cloud. The machine learning operation is then performed by using computing resources in the first edge cloud and the additional computing resources obtained from the second edge cloud.

A method for operating a system hosted on a mobile entity is disclosed, wherein the system is operable to connect to a communication network. The method, performed by a controller of the system, comprises seeking to establish a trust relationship with a cooperating system hosted on a mobile entity, and, if a trust relationship with the cooperating system is established, performing at least one of: initiating use of a resource provided by the cooperating system, or initiating provision of a resource for use by the cooperating system. Also disclosed is a method for operating a function comprising a digital representative of a system hosted on a mobile entity, wherein the system is operable to connect to a communication network. The method, performed by the function, comprises negotiating, with a digital representative of a cooperating system hosted on a mobile entity, at least one of provision of a resource to the system by the cooperating system, or provision of a resource to the cooperating system by the system.

Embodiments herein provide methods and apparatus for providing multi-provider virtual network service. A first lifecycle management, LCM, component is provided controlled by a first service provider in a virtual network, wherein the virtual network comprises a trusted LCM component controlled by a trusted provider configured to provide a decentralised trust system between a plurality of LCM components controlled by different service providers in the virtual network. The first LCM component may perform a method comprising receiving a service request to provide a first service; responsive to a determination that the first service cannot be fully provided by the first service provider, generating a first tag representing a portion of the first service that the first service provider cannot provide; transmitting a discovery request to the trusted LCM component, wherein the discovery request comprises the first tag; receiving, from the trusted LCM component based on the first tag, a list of LCM components comprising a second LCM component controlled by a second service provider, wherein the second service provider is capable of providing a part of the portion of the first service; and transmitting a provision request to the second LCM component to provide the part of the portion of the first service.

Method and machine learning agent for executing machine learning on an industrial process by using computing resources in an edge cloud. A state of the industrial process is identified () and a learning model comprising a training algorithm for the machine learning is selected () based on the identified state. The training algorithm in the selected model is then adapted () so that the amount of available computing resources in the edge cloud is sufficient for computations in the training algorithm. The adapted training algorithm is finally applied () on data generated in the industrial process using computing resources in the edge cloud. Thereby, computing resources in the edge cloud can be used and no additional resources are needed, thus reducing latency and bandwidth consumption.

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.

A system clock reference is transmitted to user devices over a short range communication channel and used to calculated a clock offset. The clock offset is stored together with a user identifier in a server memory, from which the clock offset can be retrieved when receiving the user identifier together with a video stream of video frames tagged with respective timestamps. The timestamps are converted into capture times according to a system clock using the retrieved clock offsets. Video streams from multiple user devices thereby have video frames timestamped using a same clock reference and can be time aligned.

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.

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 ().
