Tenders Are Invited For Radio Equipment – ​​Digital Train Radio System At The Rvm

Radio Equipment – ​​Digital Train Radio System At The Rvm. The Central Mcx Application Must Be Based On The 3Gpp Mcx Architecture Of The Future Communication Networks In The Railway Environment (Frmcs) And Must Therefore Be Based On Sip/Ip Communication Between End Devices, Server Systems And Applications. This Is Intended To Create A Robust But At The Same Time Adaptable System That Enables Flexible And Modular Further Development For New Innovative Services And Ensures Long-Term Conformity To International Standards. Furthermore, With Regard To Frmcs, The Mcx System Is Required To Coexist And Interwork With The Gsm-R System Of Db Infrago, Which Enables Cross-Network Communication Via Standardized Interfaces. In Addition To The Standard-Based Push-To-Talk Solution, The Required Railway-Specific Functions Such As Role- And Function-Based Calls, Emergency Calls With Associated Prioritization And Displacement Functions As Well As Additional Services And Call Control Are To Be Provided. The Rvm Intends To Use A Smartphone For The Communication Requirements Of Mobile Participants That Meets Industry Requirements And Is Equipped With An Installed Mcx Application. To Do This, The Smartphone Must Be Equipped With A Sim Card From A Public Umts/Lte/5G Network Operator. To Ensure The Best Possible Network Coverage, The Networks Of All Available Mobile Phone Providers Should Be Used. To Do This, The Sim Cards Must Be Capable Of Roaming. The Stationary Train Conductor/Dispatcher Must Be Equipped With An Associated Operator Station (Mcx Dispatcher Terminal). The Control Station Of The Train Conductor/Dispatcher (Mcx Dispatcher Terminal) Should Connect To The Central Mcx Application Server, Which Is Hosted In A Data Center, Via The Connected Lan And The Public Internet. Secure And Encrypted Connections (E.G. Via Openvpn) Are Required As A Prerequisite For Secure Communication Between Smartphones, Stationary Terminals And The Central Mcx Application Server. The Eu Nis2 Directive Must Be Observed For The Connection To The Central Mcx Application Server As Well As For Communication Between The Smartphones And The Stationary Terminals. Compliance With The Requirements Of The Nis2 Directive Must Be Demonstrated.
