METHODS FOR GENERATION AND TRANSMISSION OF SYSTEM INFORMATION, SI, IN A MOBILE TELECOMMUNICATION NETWORK, MN, AND MNS THEREOF

According to an aspect of the invention, there is provided a Mobile telecommunication Network, MN, comprising a User Equipment, UE, and a Radio Access Network, RAN, the RAN being composed of one or more RAN nodes. The RAN comprises at least: an application layer comprising one or more RAN software components configured to run on one or more infrastructure nodes; an infrastructure layer comprising: one or more Radio Units, RUs, and infrastructure nodes; an infrastructure management entity configured to manage the infrastructure nodes and/or the one or more RUs; a fronthaul interface configured to provide a data connection between the one or more RAN software components and the one or more RUs; a radio interface configured to provide a data connection between the one or more RUs and the UE. The infrastructure management entity is configured to: generate System Information, SI, elements, SI IEs, relative to the infrastructure layer, I-SI IEs, and input the I-SI lEs to the one or more RAN software components. The one or more RAN software component is configured to generate SI composed of SI lEs relative to the RAN, where a SI IE is: a SI IE relative to the application layer, A-SI IE, wherein a A-SI IE is either: configured locally by the one or more RAN software components itself; and/or received, by the one or more RAN software components, from an Operations and Management System, OAM, entity; a I-SI IE inputted by the infrastructure management entity; and/or information derived from one or more A-SI lEs and/or one or more I-SI lEs. The one or more RAN software component is configured to transmit the generated SI or information derived from the generated SI to the one or more RUs via the fronthaul interface. The one or more RUs is configured to use the information received from the RAN software to generate and transmit a radio signal comprising the SI IEs. The UE is configured to receive the radio signal transmitted by the one or more RUs.
