Abstract: Methods, devices, and a system for prediction of Radio Access Network performance. A device for training a prediction model for predicting Radio Access Network performance obtains information associated with at least one network element; determines a tag for the at least one network element, wherein the tag is based on a network environment property of the at least one network element; and determines, based on the tag, a cluster to be associated with the at least one network element. The device determines a performance indicator value for the at least one cluster, creates a training set comprising the performance indicator value of at least one cluster; and trains a prediction model using the training set. The prediction model trained by the device can be used by a device for prediction of Radio Access Network performance.

Abstract: A calibrator is employed to adjust the output of a network simulator that functions to simulate an operational network, such that the adjusted output better matches reality. The calibrator is a machine learning system. For example, the calibrator may be the generative model of a GAN.

Abstract: A method and apparatus for automatically adapting a service level for a service consumed by a terminal user in a communication network, using a service level control system (308,312,400). A service usage analyzer (308,402) collects information on service usage of the user, and estimates the user with respect to his/her service usage based on features of a usage pattern extracted from the collected service usage information. A subscription policy manager (312,412) then adapts the service level for service usage based on the user estimation, by adjusting or introducing a corresponding rule or policy in the user's subscription profile (304). The user will then consume the service with the new adapted service level.

Abstract: Method and a recommendation system (200) for making a media item recommendation to a user. A weighted graph is created (2:2) that comprises item nodes representing media items and edges linking the item nodes. Weights are also assigned to the edges based on weights of contributors shared by the linked item nodes. When an initial media item of interest to the user is identified (2:4), the recommendation system determines (2:5) a set of media items which are linked to the initial media item in a weighted graph. At least one of the determined set of media items is also selected based on the assigned weight of edges linking the media items to the initial media item. The recommendation system then provides (2:6) the media item recommendation with the at least one selected media item to the user.

The context information can be used as a trigger for the selection of a transport policy, and/or as a basis for the selection of a transport policy.

Abstract: A method and apparatus for enabling user services in a communication network with a plurality of terminal users. An initiating user terminal (200) executes a group discovery process with the terminals (202) to form a user group. Capabilities are exchanged with the terminals, including at least one of: functional resources, available services, equipment information, applications or data programs, and current traffic or connection characteristics When a group service request (R) is received from a user terminal (D) in the group, functions and actions required for the requested service are assigned to functional resources in the terminals based on the exchanged terminal capabilities. The requested group service can then be consumed by means of these functional resources without involving an operator controlled group management server.

Abstract: Method and apparatus in a router of an IP network, for providing a relevant and expected service level for a first subscriber (A) in a peer-to-peer session with a second subscriber (B). When a session setup message (PATH) sent from the first subscriber is received (2:2) at the router, a required service level is detected from a service level indicator in the received message, and a service level definition of an operator of the first subscriber is obtained (2:3) for interpreting the service level indicator. Communication resources required for data transmission during the session are determined (2:4) according to the detected service level as interpreted by the service level definition. The determined communication resources are then booked (2:4) in the router, and the session setup message is forwarded (2:7) to a next hop node in the transmission path towards the second subscriber.

Abstract: A technique for providing a service availability indication to a user terminal is described. In a method realization, the technique comprises providing a data structure representative of user terminals and of inter-terminal relationships derived from one or more communication parameters pertaining to communications between the user terminals. Additionally, for at least some of the user terminals service utilization information for each of a plurality of services is provided. The technique further includes selecting, for at least one user terminal and from the plurality of services, a service not used by the at least one user terminal, wherein the service selection is based on the service utilization information provided for user terminals having a predefined association with the at least one user terminal as determined by the inter-terminal relationships, and sending a message indicative of the selected service to the at least one user terminal.

Abstract: Method and apparatuses for controlling a peer-to-peer communication involving media communication between a subscriber (A) and one or more opposite peers (B, C, D). When a policy node (300) detects that the peer-to-peer communication is activated for the subscriber, session parameters are determined (3:4) for the media communication based on predefined peer-to-peer service rules configured (3:1) at the policy node. The session parameters are then implemented (3:6) in an access gateway (304) that controls network resources for the media communication.

Abstract: A method and apparatus for offering a service to at least one client in a communication network for a specific client context, by means of a service provisioning unit. A history of client activities involving service usage in associated client contexts, is recorded in an activity database. Service templates are composed for associated client contexts based on the recorded history of client activities. When a context detector detects that the specific client context prevails, a service configurator selects a service template for the detected client context and configures a customised service from the selected service template. The customised service can then be offered to the at least one client.

Abstract: A recommendation apparatus for determining, for a user, a set of one or more recommended paths through an information space in response to receiving from the user a path request message. Advantageously, in some embodiments, the path recommender apparatus determines a recommended path by analyzing a set of paths, where each path in the set was traversed by a person who is in a “social graph” belonging to the user (e.g., each path in the set was traversed by one of the user's Facebook friends). In this way, paths can be recommended to the user based on paths that are popular with the user's friends.

Abstract: Application servers and methods of operating the same are provided for generating a personalized recommendation of items to a first user. An updated rating value N(t) of an initial rating value N(0) is determined for each rated item based on an age of each rating. The updated rating value N(t) is based on a difference between the value of the initial rating N(0) and a neutral rating value R, and on a predetermined half-life of the ratings. The updated rating value N(t) converges towards the neutral rating value R with an increase in the age t for each rating.
