Method and an apparatus for publishing assertions in a distributed database of a mobile telecommunication network and for personalising internet-of-things devices

Abstract

This invention relates to a method for granting, for a mobile device which is not provisioned with a subscription to access a wireless network, the establishment of an initial wireless communication over a second wireless network (Se-PLMN) operated by a second wireless network operator (Se-MNO), the mobile device belonging to a user, the method comprising the steps of: receiving () by the second wireless network (Se-PLMN) an identifier of the mobile device; verifying (), in an immutable distributed database hosted by a first wireless network operator (Fi-MNO) and the second mobile network operator (Se-MNO) in which data is replicated across a plurality of compute nodes of a network, if at least a published assertion comprising said identifier of the mobile device demonstrates that the user owns a first subscription to the first mobile network operator (Fi-MNO), said subscription allowing said first operator (Fi-MANO) to be charged by the second mobile network operator (Se-MNO) for the establishment of a wireless communication over the second wireless network; in case of a positive verification, granting the establishment of a wireless communication () over the second wireless network (Se-PLMN) for the mobile device to be provisioned with a second subscription of a third wireless network operator (Th-MNO).
