A method for a physical random access channel (PRACH) attack detection includes detecting by a base station a plurality of preambles sent by devices through a PRACH; launching by the base station a random access (RA) procedure for at least one device for which a preamble has been detected; decoding by the base station at least one radio resource control (RRC) connection request received in the context of a launched RA procedure; determining by the base station a first metric and a second metric, wherein the first metric is the number of RRC connection requests successfully decoded over time, wherein the second metric is the number of preambles detected over the same time and for which a RA procedure has been launched; determining whether there is a suspicion of storm attack over the PRACH based on a result of a comparison of the first and second metrics.

The present subject matter relates to an apparatus for handover of a user equipment into a target base station of communication system, the apparatus comprising means, the means being configured for: in response to selecting the target base station for handover of the user equipment to the target base station performing a first handover method by at least: comparing a current set of cell measurements of the user equipment with reference sets of cell measurements for determining whether the target base station is a fake base station; performing a handover of the user equipment based on a determination that the target base station is not a fake base station.

A method comprising: retrieving update rules stored in a distributed ledger from the distributed ledger; checking whether or not a received initial transaction fulfills all the retrieved update rules; creating a block comprising the initial transaction if the initial transaction fulfills all the retrieved update rules; broadcasting the block into a network of the distributed ledger, wherein, the initial transaction requests to modify a content of a slice and/or an intent of the slice; if the initial transaction requests to modify the content of the slice, at least one of the update rules constrains the content of the slice or the modifying of the content of the slice, and if the initial transaction requests to modify the intent of the slice, at least one of the update rules constrains the intent of the slice or the modifying of the intent of the slice.
