- An implementation of the 5G Core network by the OpenAirInterface community.
-
-------------------------------------------------------------------------------
-
-OPENAIR-CN-5G is an implementation of the 3GPP specifications for the 5G Core Network.
-At the moment, it contains the following network elements:
-
-* Access and Mobility Management Function (**AMF**)
-* Session Management Function (**SMF**)
-* User Plane Function (**UPF**)
-
-Each has its own repository: this repository (`oai-cn5g-smf`) is meant for SMF.
-
-# Licence info
-
-It is distributed under `OAI Public License V1.1`.
-See [OAI Website for more details](https://www.openairinterface.org/?page_id=698).
-
-The text for `OAI Public License V1.1` is also available under [LICENSE](LICENSE)
-file at the root of this repository.
-
-# Where to start
-
-The Openair-CN-5G SMF code is written, executed, and tested on UBUNTU server bionic version.
-Other Linux distributions support will be added later on.
-
-More details on the supported feature set is available on this [page](docs/FEATURE_SET.md).
-
-# Collaborative work
-
-This source code is managed through a GITLAB server, a collaborative development platform:
-
-*  URL: [https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-smf](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-smf).
-
-Process is explained in [CONTRIBUTING](CONTRIBUTING.md) file.
-
-# Contribution requests
-
-In a general way, anybody who is willing can contribute on any part of the
-code in any network component.
-
-Contributions can be simple bugfixes, advices and remarks on the design,
-architecture, coding/implementation.
-
-# Release Notes
-
-They are available on the [CHANGELOG](CHANGELOG.md) file.
-
-# Repository Structure:
-
-The OpenAirInterface CN SMF software is composed of the following parts:
