Abstract: To enable end-to-end performance monitoring, different solutions to obtain end-to-end values for different key performance indicators are disclosed. For example, when key performance indicator data from a plurality of different domains is received, the key performance indicator data received may be adapted to be a time-series data stream. Then, values of key performance indicators may be extracted, per a domain, from the time-series data stream. An end-to-end value for a key performance indicator may be determined, based on the extracted values of the key performance indicator in the different domains. The end-to-end value may be used for end-to-end performance monitoring of a network.

Abstract: According to an aspect, there is provided an apparatus configured to perform the following. The apparatus hosts a plurality of applications for managing network functions of a radio access network and schedules them for one or more future time slots. The apparatus obtains one or more predicted future values of one or more network parameters of the radio access network for the one or more future time slots. The apparatus determines whether or not at least one conflict exists in the scheduling of the plurality of applications based on the one or more predicted future values of the one or more network parameters. In response to determining that the at least one conflict exists, the apparatus resolves the at least one conflict by adjusting scheduling of at least one application involved in the at least one conflict.

Abstract: There is provided a method for radio access network slicing. A first set of radio access network, RAN, statistics and a second set of RAN statistics are received. The first set of RAN statistics comprises non real time statistics from the RAN. The second set of RAN statistics comprises near real time statistics from the RAN. The first set of RAN statistics and a service level agreement are provided to a non real time reinforcement learning model as input. Resource management policy per slice is obtained as output from the model. The second set of RAN statistics, the service level agreement and the resource management policy per slice are provided to a near real time reinforcement learning model as input. Resource allocation per slice is obtained as output from the model.

Abstract: In a method for routing communications through a constellation (100) of a plurality of CubeSats orbiting a planet and responsive to a ground controller, the ground controller determines optimal tunnels (210) that include inter-satellite links (122) between CubeSats by: generating virtual nodes (110); generating the sub-satellite points (120) to correspond to points on a path through each virtual node that CubeSats follow; calculating an inter-satellite link from a sub-satellite point another sub-satellite point during a period from a time of initialization when the first sub-satellite point is at an entry point of the first virtual node until the first sub-satellite point is at an exit point; and generating an information packet describing the optimal tunnel (210) including inter-satellite links (122) that interconnect the sub-satellite points (120). The information packet transmitted from the ground controller to one of the CubeSats and is forwarded from one of the CubeSats to remaining CubeSats.

Abstract: A space-based communications network (100) includes at least one central ground station (116) having a transceiver that is configured to communicate with satellites, such as cube satellites (110). The cube satellites (110) form an ad hoc network of orbital cube satellites, in which each of the cube satellites (110) communicate with each other. One of the cube satellites communicates with the ground station (116). A ground-based control system (1000) communicates with the central ground station (116). The control system (1000) continuously determines a configuration of the ad hoc network (100) and communicates network control information for the cube satellites (110) to maintain communications in the ad hoc network (100). The cube satellites (110) disseminate the network control to each other via the ad hoc network (100).

Abstract: A computational framework for designing a constellation that includes a plurality of cube satellites (CubeSats) includes an orbit propagation module, a coverage estimation module, a connectivity estimation module and an annealing module. The orbit propagation module receives a plurality of static parameters for the constellation and determines a position vector, a ground track and sub-satellite points for each of the plurality of CubeSats. The coverage estimation module receives the plurality of static parameters for the constellation and estimates Earth coverage for the constellation. The connectivity estimation module receives the plurality of static parameters for the constellation and determines active inter-satellite links (ISL) in the constellation. The annealing module receives input from the orbit propagation module, the coverage estimation module and the connectivity module and employs an annealing algorithm that generates a constellation design.
