Methods for generation and transmission of system information, SI, in a mobile telecommunication network, MN, and MNS thereof

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,

• wherein the RAN comprises:
• 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;
• and a radio interface configured to provide a data connection between the one or more RUs and the UE,
• wherein:
• the one or more RAN software components are configured to:
• generate System Information (SI) composed of SI information elements (SI IEs), comprising information relative to the application layer (A-SI), wherein the A-SI 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;
• and transmit the generated SI or information derived from the generated SI to the one or more RUs via the fronthaul interface;
• the infrastructure management entity is configured to:
• generate information elements (IEs) relative to the infrastructure layer (I-SI IEs) and input the I-SI IEs to the one or more RUs;
• the one or more RUs are configured to generate and transmit a radio signal containing SI IEs composed of:
• the I-SI IEs;
• and/or the A-SI IES;
• and/or information derived from one or more A-SI IEs and/or one or more I-SI IEs;
• and
• the UE is configured to receive the radio signal transmitted by the one or more RUs.

A method for generation and transmission of System Information (SI) in 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, wherein the RAN comprises at least:

• an application layer comprising one or more RAN software components running on one or more infrastructure nodes;
• an infrastructure layer comprising one or more Radio Units (RUs), and infrastructure nodes;
• an infrastructure management entity managing the infrastructure nodes and/or the one or more RUs;
• a fronthaul interface providing a data connection between the one or more RAN software components and the one or more RUs;
• a radio interface providing a data connection between the one or more RUs and the UE, the method comprising the steps of:
• generating, by the infrastructure management entity, System Information (SI) Elements (SI IEs), relative to the infrastructure layer (I-SI IEs), and inputting the I-SI IEs to the one or more RAN software components;
• generating, by the one or more RAN software components, SI composed of SI IEs relative to the RAN, where an SI IE is:
• an SI IE relative to the application layer (A-SI IE), wherein an 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;
• an I-SI IE inputted by the infrastructure management entity;
• and/or
• information derived from one or more A-SI IEs and/or one or more I-SI IEs;
• transmitting, by the one or more RAN software components, the generated SI or information derived from the generated SI to the one or more RUs via the fronthaul interface;
• generating and transmitting, by the one or more RUs, a radio signal comprising the SI IEs by using the information received from the RAN software;
• and
• receiving, by the UE, the radio signal transmitted by the one or more RUs.
