The 5G AAS has been defined and implemented at the UWICORE laboratory of the Universidad Miguel Hernandez de Elche (Spain).

Abstract

5G is a fundamental technology for the full digitalization of smart manufacturing. The use of Asset Administration Shells (AAS) can facilitate the integration of 5G with Industry 4.0 systems and applications while minimizing the complexities associated with the 5G network management. This study presents the design and implementation of the first full 5G system AAS that is openly released to the community. It includes a 5G UE (User Equipment) AAS and a 5G NW (network) AAS that have been designed following the 5G-ACIA guidelines as well as the Plattform Industrie 4.0 and 3GPP standards. The AASs have been defined to provide and expose the data and capabilities of 5G necessary to facilitate the integration of 5G with Industry 4.0 systems and applications.

Features

This code creates 5G NW and UE AASs in python. The AASs has been defined following the 5G-ACIA guidelines as well as the Plattform Industrie 4.0 and 3GPP standards. This code uses the Basyx-Python-SDK. The repository also includes the aasx files of the 5G UW and NW AASs implemented in AASX Package Explorer. The code reads the AASs contained in aasx files previously created in AASX Package Explorer.

Project Structure

The code from this repository mantains the folder structure of basyx python sdk because it is programmed using it. The main contribution is the code contained in the basyx/aas folder, where we can find the code programmed that will generate this AAS objects in python.

File Content
AAS5Gsubmodels.py This script defines the different classes created for the Network and UE AAS programming like the UE5G or the Network5G classes. This classes inherits the Basyx python sdk classes.
NW_5G_AAS.py This script reads the 5G_Network_AAS.aasx file created with AASX Package Explorer and generates the 5G Network AAS python object.
UE_5G_AAS.py This script reads the 5G_UE_AAS.aasx file created with AAS Package Explorer and generates the 5G UE AAS python object. It generates as many UEs as defined in the AASX file.
ExampleUse.py This script imports the Network and the UEs objects and provides examples of use of the AAS defined.
5G_Network_AAS.aasx 5G Network AAS model in an AASX file from AASX Package Explorer.
UE_5G_AAS.aasx 5G UE AAS model in an AASX file from AASX Package Explorer.

Dependencies

The 5G AAS Python requires the following Python packages to be installed for production usage. These dependencies should be installed with pip:

  • Basyx-python-sdk
  • Math

Getting Started

Installation

Clone this repository via download or via git clone. Terminal commands needed in the python terminal for the creation of AAS.

pip install basyx-python-sdk

Complementary command for mathematic operations.

pip install math

Example

Terminal command for moving to the folder

cd basyx/aas

If you want to create just a 5G UE AAS and a 5G Network AAS instance, the scripts are already programmed with the default values of identification from the submodels and the AAS from the .aasx models. For this reason, the AAS will be already instanciated in ExampleUse.py and it can be used in any other python script. Here we can see some examples of the code of ExampleUse.py. At first, we import the AASs, secondly we print some parameters of the AAS or even about some of their properties. Finally, we change values from some properties of the first 5G UE AAS (contained in listOfUeAASs) the and about the 5G Network AAS.

#Imports
from AAS5Gsubmodels import *       #Here we have the created structure for the AAS
#We need to import the AASs
from NW_5G_AAS import aasnw5G
from UE_5G_AAS import listOfUeAASs
print(listOfUeAASs[0].id_short)
print(aasnw5G.id_short)
print(listOfUeAASs[0].ueAttachAndConnectionStatus.pduSessionList.pduSessions[0].qosFlowList.qosFlows[0])
#Changing some values
listOfUeAASs[0].ue5GIdentification.permanentEquipmentIdentifier.value=2976
aasnw5G.connectivity.uesAttachedList.uesAttached[0].gpsi.value=8427

Personalized use

The values and the valuetypes of properties must have a value when you personalize an AAS in AASX Package Explorer! If you want to create more than one AAS for the UE, you can use the AASX Package Explorer with the 5G_UE_AAS file. In Workspace/edit mode, click on the AAS and use "Copy," then in the "Administration Shells" section, choose "Paste into." Do the same with the asset in the "Assets" section and link it with the previous AAS. You should notice that it copies the AAS and the asset entirely, so they will have the same IRIs in the AAS, asset, and the submodels. To ensure each can be uniquely identified, it's necessary to change the IRIs of the AAS and the asset. Changing the IRIs of the submodels is not as direct. To do this, first copy the submodel in the "All Submodels" section, then in the new one, generate a new random IRI. After that, go to the new AAS, delete the "SubmodelReference" of the copied submodel, and then "Add existing." Select the submodel with the new IRI. Repeat this process for every submodel.
