Abstract: A database stores self-operation cases for slice reselection requests received by a network function virtualization (NFV) system. The self-operation cases include reasons, contexts, remedial actions, and results of the remedial actions for the slice reselection requests. A set of detection rules identifies at least one issue causing the slice reselection requests based on reasons for the slice reselection requests and contexts of the slice reselection requests. The set of detection rules are applied to the self-operation cases to identify the at least one issue and a remedial action is selected to address the at least one issue. The remedial action is performed to reconfigure the NFV system and the processor determines whether the remedial action successfully resolved the at least one issue. Setting status flags for affected cells or slices prevents slice reselections to the affected cells or slices until the at least one issue is resolved.

Abstract: There is provided a method comprising receiving at least one request from a first function instance of a self-organising network, comparing said first function instance and a second function instance effective in the self-organising network to determine whether the first function instance and the second function instance overlap, and, characterised by, receiving operational stage information of the first function instance and if the first function instance and the second function instance overlap using said operational stage information in determining which of the first and second function instance to nm in dependence on which of the first function instance and the second function instance has higher priority and causing the determined instance to be run.

Abstract: A method includes learning, by at least one device associated with a slice selection function, a slice reselection decision for at least one self-operation case. The method includes determining, by the at least one device associated with the slice selection function, whether an evaluation condition for at least one new self-operation case has been met. The at least one new self-operation case includes the at least one self-operation case. The method also includes requesting, at least one device associated with a management function, evaluate the at least one new self-operation case in response to determining that the evaluation condition has been met, receiving evaluation results from the at least one device associated with the management function, and learning the evaluation results.

Abstract: In an example, a mobile network apparatus is configured to operations support systems, OSS, including at least one processor, and at least one memory storing program instructions that, when executed by the at least one processor, cause the apparatus to: request, by a coordination function of the OSS, information relating to an uncoordinated function or an instance of an uncoordinated function, wherein the uncoordinated function or the instance of the uncoordinated function is related to the coordination function; receive, by the coordination function, a response including the information; based on the response, control, by the coordination function, the uncoordinated function or the instance of the uncoordinated function. In other examples, a method and a computer program product have been discussed along with the features of the mobile network apparatus.

Abstract: In a first aspect, this specification describes a method which comprises including, in a network slice selection request, information indicative of a reason for making the network slice selection request. The method of the first aspect may, for instance, be performed by a user equipment (UE). In a second aspect, this specification describes a method which comprises determining a response to a network slice selection request from a UE based on information included in the network slice selection request that is indicative of a reason for making the network slice selection request. The method of the second aspect may, for instance, be performed by a network control function (e.g. a CCNF).
