- There is an edge server per station and the edge server can determine which platform trains stop and transmit/receive data to onboard UEs of Trains 1&2 through the 3GPP network.
- Each edge server can... |
5eaf1b94c89939407995fc52470817be | 22.890 | 5.2.3 Service Flows | 1. Train 1 is stopping at Platform A of the smart station, and Train 2 is approaching. Trains 1 & 2 are connected and authorized to transmit/receive information to the server at the smart station.
2. The server determines that Train 2 stops at Platform A. The server informs Train 2 of the platform where Train 2 will st... |
5eaf1b94c89939407995fc52470817be | 22.890 | 5.2.4 Post-conditions | - Train 1 establishes a connection with the server at the next station while Train 1 has a connection with the server at the current station.
- When the distance between Trains 1 and 2 becomes longer, Trains 1 and 2 stop sharing the information and disconnect from each other. |
