Simulator of the 5G Core Network (specifically, the registration procedure).
The simulator is comprised of seven Network Functions and contains all the services and models required by the registration procedure. It was built primarily with NF interaction (and the data that is part of these interactions) in mind. Therefore, it is possible to alter every data field that is sent at each step of the procedure. This allows us to analyse the characteristics of different types of data flowing through the system.
As part of the registration procedure, information about the User Equipment is randomly generated based on the required formats of the data. This information is used as the basis for the rest of the procedure. This approach was chosen because it allows for more granular control of the data used in the simulation than attaching a UE-RAN simulator.
Important information about NF requests and responses (such as size, body contents, duration, metadata) is recorded and saved to log files. The purpose of this is to use the information as part of an analysis.
MongoDB is used for the storage needs of this simulator. During the registration procedure, data is inserted, updated, retrieved, and deleted as necessary.
As required in the 5G Core Network, TLS provides end-to-end encryption for all traffic between the NFs.
- In VS Code terminal, run:
go get github.com/tommcclymont/TM5GProject
- Navigate to project folder. This should be $GOPATH/src/github.com/tommcclymont/TM5GProject.
After navigating to the project directory, run the following commands to start the NF servers. Each command must be run in a new terminal.
go run AMF/amf.go
go run AUSF/ausf.go
go run EIR/eir.go
go run OldAMF/oldamf.go
go run PCF/pcf.go
go run SMF/smf.go
go run UDM/udm.goNow that all the servers are running, begin the registration procedure:
go run registration.go
