Abstract: The present invention enables a network operator to select a gateway that provides desirable operational parameters to access a network node function in a network node requested by a client. A network service provider detects what service a client device is requesting or using and selects a gateway (e.g. PDN-GW) to deliver the service. The client device is signaled to make a new connection to the network using the selected gateway, e.g. by connecting to the APN associated with the PDN-GW that delivers the service.

The system is further configured to transmit the relay configuration information to the relay devices. The relay device of the invention is configured receive a data unit from a further device (21) or not in dependence on the received relay configuration information and/or relay a received data unit to the cellular communication network (31) or not in dependence on the received relay configuration information.

Abstract: A control system enables re-registration of user equipment (UE) on an alternative network in the event of a partial failure of a network (VPLMN) for wireless communication. An access and mobility management function (AMF) manages the communication to user equipment (UE) via network slices (1,2,3). A slice priority management function (SPM) receives data indicative of a change in the network's ability to maintain the instantiated network slices and determines to reduce services via affected network slices. Before said slice reduction, the access and mobility management function is informed and sends a slice reduction message to the user equipment.

It may be desirable to provide guarantees on the minimum resource availability of the shared resource per network slice. Accordingly, a slice resource distribution function (SRDF) may be provided which may be configured manage the resource utilization of the shared resource which may safeguard guarantees on the minimum resource availability per network slice.

Abstract: A combiner system may be provided for combining, in a compressed domain, video streams of different media sources in a composite video stream by including a respective video stream as independently decodable spatial segment(s) in the composite video stream. The combiner system may generate composition metadata describing a composition of the spatial segments in the composite video stream and identification metadata comprising identifiers of the respective video streams. A receiver system may obtain decoded video data of a respective video stream based on the composition metadata and a decoding of the composite video stream, and based on the identification metadata, identify a process for handling the decoded video data. Thereby, the composition of spatial segments may dynamically change, while still allowing the receiver device to correctly handle the spatial segments.
