A network slice managing entity, comprising means configured to obtain a service request for a network slice, the service request defining service requirements; request network slice descriptions from a database and selecting at least one network slice which support said service requirements according to the descriptions; generate a resource graph comprising nodes representing infrastructure resources and links representing connections between the nodes, the resource graph depicting resources needed for providing the service, wherein the generating is carried out based on a network slice description of the selected at least one network slice; transmit the resource graph to an infrastructure manager for mapping a topology of said network infrastructure onto said resource graph and determining at least one subset of said network infrastructure; and, receive a mapping result from said infrastructure manager containing said at least one subset of said network infrastructure.

There is described therein a method of roaming between 5G networks operator for selecting a network operator in a visited country when a mobile network user exits an area covered by a home network operator to enter the visited country covered by a plurality of visited network operators. This method of roaming is based on the concordance between the VNF supported by the visited country network and the network profile of the user. The network profile of the user embeds both the functions commonly chained in his home network to deploy the services corresponding to his usage and the functions required in the visited country network to perform the services desired by the user. Therefore, by matching this profile with VNF capabilities deployed by a network the invention allows a better user satisfaction in roaming situations providing them with the most suitable network.

Mobile device roaming based on user's network profile

The invention related to a method for transmitting video contents from a server to a terminal of a user within service periods (S) of a radio transport channel, each video content being encoded by using scalable codec technology for integrating a scalable codec base layer (b, b, b, b) and at least one enhancement layer (e, e, e, e), each service period (S) comprising: &#x2014;at least one multiplexed time-sliced radio burst (A, A') comprising at least a part of the base layers (b, b, b, b); &#x2014;several multiplexed time-sliced radio bursts (B, C, D, E) comprising the enhancement layers (e, e, e, e) and the eventual remaining base layers (b, b, b, b); said method enabling to permute, between two consecutive service periods (S), the transmission order of the enhancement layers bursts (B, C, D, E).

Within a user device to which a radio communication network infrastructure transmits data carried by a sequence of frames broadcast to the user device, each frame comprising a first section comprising data and a second section comprising redundancy information associated with the data of a predetermined number B of previous frames in the sequence, a number of consecutive lost frames is compared to a threshold dependent on the number B of previous frames with which said redundancy information is associated and encoding parameters that generate said redundancy information, and a request to retransmit at least one of the consecutive lost frames is sent to the radio communication network infrastructure if the number of consecutive lost frames exceeds said threshold.
