A technique of triggering transition control between different RRC states of wireless terminal devices is described. A method aspect of this technique comprises receiving a request for an RRC state transition control for a terminal device, wherein the request includes at least one identifier associated with the terminal device. The method further comprises obtaining a temporal inactivity parameter associated with the at least one identifier, wherein the temporal inactivity parameter depends on an estimated period of time between two traffic activities of the terminal device. Further still, the method comprises triggering, based on the temporal inactivity parameter or a parameter derived on the basis of the temporal inactivity parameter, the RRC state transition control for the terminal device.

Transition control between radio resource control states

Selecting a transport configuration for a data network adapted to transport data traffic belonging to different traffic types. A selecting device determines an actual traffic mix of traffic types and corresponding traffic loads transported on the data network. The device determines, based on the actual traffic mix, multiple future traffic mixes of traffic types and corresponding traffic loads, wherein the future traffic mixes are associated with probability values and classifiable into different future traffic mix classes, each future traffic mix class being associated with a predefined transport configuration capable of handling any future traffic mix falling in that future traffic mix class. The device is configured to aggregate the probability values associated with those future traffic mixes that belong to the same future traffic mix class and to select the transport configuration associated with the highest probability value across the aggregated and non-aggregated probability values.

Techniques for real-time encrypted over-the-top (OTT) data quality analysis are presented. For instance, the present disclosure includes an example method performed by a device in a recurrent neural network (RNN) implemented in a data communication system. The method includes periodically obtaining information corresponding to one or more OTT data sessions in the data communication system, the information being obtained from one or more of a packet probe, a test terminal, and a network node. The method also includes generating at least one quality metric associated with the one or more OTT data sessions based on the periodically obtained information. Related devices, processor and memory arrangements, methods, and computer programs are also presented.

A performance monitoring system and method is based on a Detailed Call Record (DCR). A DCR contains records of events occurring in different network domains () that are related to a single, specific VoLTE call. The DCR events for each VoLTE call cover all legs of the call, and for each call leg, the relevant events are ordered by time. A DCR also contains basic information to identify the call: the IMS Charging Identifier (ICID), the International Mobile Subscriber Identity (IMSI) of all involved subscribers, and the start and stop timestamps of the call. A DCR has all the relevant user plane measurement, radio measurement, and control plane data from all the involved domains () for all call legs of a VoLTE call, in contrast to prior art systems that focus only on a single subscriber's activities for a given call. The DCR thus provides a complete view of the call, allowing more complete analytics and troubleshooting. Furthermore, the data are collected and assembled automatically, with results available real-time, or with a few seconds delay.

The present disclosure relates to a technique for configuring and collecting network performance measurements in a mobile communications network, the mobile communications network comprising at least one network node and at least one mobile terminalconnected to the at least one network node, implementing a Minimization of Drive Tests (MDT) trace measurement configuration and collection. A method embodiment comprises the steps of performing, in the at least one mobile terminal, a service specific measurement based on a service specific measurement configuration, wherein the service specific measurement includes determining one or more quality metrics related to at least one of one or more services, one or more service types, one or more bearers, one or more applications and one or more application types provided in the mobile communications network, to obtain a result of the performed service specific measurement and generating, in the at least one mobile terminal, active test traffic based on an active measurement configuration to perform an active measurement, wherein the active measurement uses the generated test traffic to obtain a result of the performed active measurement, the result of the performed active measurement indicating the performance of the test traffic in the mobile communications network.

A network management system () and a method are described herein that are capable of identifying and accessing Quality of Service (QoS) issues within a communications network (). In one application, the network management system () includes a service performance unit (), a service performance database (), a factor scoring system (), a factor score database () and a factor strength analysis module ().

Network management system and method for identifying and accessing quality of service issues within a communications network

A method and apparatus for controlling data traffic in a communications network. The server determines that network conditions are suitable for sending delay tolerant data traffic, and as a result of the determination, it transmits a grant message to at least one client device, the grant message informing the client device that it is permitted to send or receive delay tolerant data traffic.

Data traffic control in a communication network

In existing mobile networks, users may be traced to troubleshoot problematic user connections, monitor generic network performance, and to perform root cause analysis to identify network problems. However, the existing tracing methods provide incomplete trace information. To address this and other issues, early tracing recording is enabled in which an involved trace entity starts recording the trace data when any initial activity related to the user equipment is detected. The trace entity can continue the trace if a trace trigger is later confirmed or may discard the trace data if the trigger is not confirmed.

A subscriber portfolio model is created by forming mutually exclusive and completely exhaustive groups of subscribers in a way that maximizes the intra-group similarity and inter-group dissimilarity of the value of a target attribute among subscribers in the groups. The subscriber groups thus generated are self-descriptive, as the groups are defined by the attributes used to form them. A segmenting algorithm groups subscribers along permutations of attributes. Relevant data about subscribers is collected from various sources, correlated, and subscriber identities removed to ensure privacy. After analyzing the aggregated data, a subscriber portfolio model is built. The subscriber portfolio model is created in an iterative process; in each step, a selected subscriber group is subdivided into smaller subscriber groups along different value ranges of a statistically decisive attribute that is selected and evaluated based on specific methods. The subdivision is performed by computing filtering conditions based on an in-depth statistical analysis.
