The invention relates to a communication network which is configured to enable instantiation of network slices which represent virtual networks. The invention further relates to a content application server (CAS) for providing an application service via a network slice to at least one user equipment (UE). A network function (SREF) is provided which on the one hand may have access to one or more slice management network functions (CSMF, NSMF, NSSMF) and on the other hand may be accessible to the CAS. The network function (SREF) may abstract the properties of the network slice using a data structure representing a slice object and expose these abstracted properties to the CAS by providing access to the slice object. The slice object may comprise modifiable properties which represent modifiable properties of the corresponding network slice. The CAS may at least in part manage the network slice by modifying one or more modifiable properties, and the SREF may then translate the modified properties into one or more requests for the slice management network functions. The SREF may thereby enable the CAS to perform slice management, while at the same time reducing the complexity of the slice management.

An interface may be provided between i) a selective forwarding unit (SFU) configured to, in real-time, receive a data stream from a sender via a first network link of a communication network and selectively forward the data stream to one or more receivers via respective second network links, and ii) one or more core network functions (PCF, PCRF, NSMF, CSMF) for establishing service guarantees for data flows in the communication network. In a specific example, the interface may be established as a network function (SMGF) which translates streaming requirements for one-to-many flows coming from WebRTC SFUs into appropriate QoS/network slice configurations, such that the quality of RTC flows may be increased. Accordingly, negative side-effects of conservative congestion control algorithms in WebRTC clients and static/overprovisioned QoS at network operators may be overcome.

An intermediary system and method may be provided for assisting a receiver system in processing video data which is streamed as a video stream to the receiver system via a network. The processing of the video data by the receiver system may be dependent on an analysis of the video data. The intermediary system may provide processing assist data to the receiver system which comprises an analysis result or a processing instruction derived from the analysis results. Accordingly, the receiver system may process the video data without a need for the receiver system itself to analyze the video data, thereby offloading computational complexity to the intermediary system. Compared to techniques in which most or all of the processing is performed by the intermediary system, an advantage of continuing to process the video data at the receiver system is that the receiver system may already decode the video stream while the video stream is decoded and/or analyzed by the intermediary system, thereby reducing the delay from transmission to display of the video stream.

In an embodiment, a slice priority manager receives, from a network services node, data indicating changes in network resources available for maintaining instantiated network slices in a communication network. Based on the received data, changes in the network services node's ability to maintain the instantiated network slices are identified and a communication service provider is notified of the change. To continue, slice priority data that indicates a preferred order of a portion of the network slices for allocating the network resources is received from the communication service provider. In turn, an indication of the slice priority data is forwarded to the network services node to update allocation of network resources for the slices.

A method and processor system are provided for adapting an acoustic rendering of an audio source to a visual rendering of an image-based object. Such visual rendering may be in virtual-reality (VR) or in augmented-reality (AR). The image-based object may be modelled, and an audio object representing the modelled object may be established in an acoustic scene containing the audio source and being associated with the visual rendering. The audio object may be assigned a reverberant and/or absorbent property, and the acoustic rendering may be adapted to the audio object. This way, the acoustic rendering may be adapted to image-based objects, and a user may perceive the acoustic rendering as better matching the visual rendering.

A processor system processes image data for rendering a virtual environment for a user present in a real environment. The system receives head tracking data indicative of the orientation of the head of the user. An image processor generates image data for rendering a viewport of the virtual environment on a display system based on the head tracking data. A real-view area is defined in the virtual environment, having at least one boundary. The boundary corresponds to predetermined coordinates in the virtual environment. Thereby a corresponding part of the real environment is made visible in the real-view area, the part showing the real environment as perceived from the user head pose. Effectively the virtual environment is augmented by integrating part of the real environment via the real-view area.

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. In the UE an alternate network selection function (ANSF) receives the slice reduction message and selects an alternate network based on the user information (USIM) and the slice reduction information, and triggers registration on the selected alternate network for transferring at least part of the affected services to a network slice of the selected alternate network.
