Proof of concept for LI infrastructure in 5G SA Core. pyli5 is part of the P3LI5 and provides the components to simulate a new protocol allowing privacy-preserving LI on 5G. pyli5 only supports modified message protocols to perform private LI. However it provides modules for parsing X1 and H1 messages as per ETSI and 3GPP specifications (TS 133 127, TS 133 128, 103 221, 103 120) and can support LI_HI1, LI_HIQR. LI_XQR, LI_XEM and LI_XER interfaces. There is no current support for TLS. Components are meant to be deployed using Docker following P3LI5.

We provide scripts in the form of start_*.py for bootstrapping the various components.

We already provide the Python bindings for GRPC. This is how they were generated (for reference):

• Install grpc:

pip install grpcio
pip install grpcio-tools

• Run protoc inside src/pyli5/lea:

python3 -m grpc_tools.protoc -I . --python_out=. --grpc_python_out=. client.proto

• Fix imports:
  • in client_pb2_grpc.py:

  import pyli5.lea.client_pb2 as client__pb2
  

• Same applies for icf.
