Abrégé
Next generation network architectures enable instantiation of network slices in which traffic may be transported via one or more virtual networks overlaying the physical network infrastructure. To enable a slice management system to be able to obtain information on virtual networks of instantiated network slices, such as utilization data indicative of at least one of: a bandwidth capacity, computing capacity and storage capacity of one or more physical links via which traffic of the virtual networks is routed, an interfacing system is provided. The interfacing system may establish an interface between the slice management system operating in the domain of network slices and the network management system operating in the domain of physical network equipment, and thereby enable the slice management system to take into account such utilization data in its slice management operation.

Abrégé
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.

Abrégé
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.

Abrégé
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.

The primary content and the secondary content are provided to a receiver via a managed content delivery network configured for IPTV delivery. The secondary content may be personalized content, such as an ad. Both the primary content and the secondary content may be encrypted, and decryptable with different decryption keys. Measures are described for pre-caching the decryption key for the secondary content at the receiver ahead of a scheduled play-out time of the secondary content. By pre-caching the decryption key, an interruption in play-out may be avoided or reduced compared to a basic scenario in which the receiver requests the decryption key at or immediately before the scheduled play-out time.

Abrégé
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.
