The railway station is a major touchpoint to customers including passengers. The railway community is considering the Railway Smart Station services for the railway station operations and customers. Many railway companies are planning to adopt the Railway Smart Station services and some companies have already launched their own projects to provide such services over Mission Critical Services (MCPTT, MCVideo, MCData Services). TR 22.889 / TR 22.989 provides basic requirements and focuses on the railway communication system having three categories critical, performance and business communications. While the critical and performance communications address the safe movement of trains, business communications provide value-added services for passengers. The Railway Smart Station services provide assistance of station operation and value-added services for passengers, e.g., subway station evacuation guidance via the passenger's UE. The objectives of this technical report are as follows:

• Study use cases related to Railway Smart Station Services and deduce requirements from those. For example:
  • Use cases of station operation monitoring and control
  • Use cases of passenger supporting services
  • Evolution use cases of business and performance applications currently included in TR 22.889 / TR 22.989
• Analysis gaps between the requirements identified and the functionality already provided by 3GPP (e.g., TS 22.261, TS 22.228, or MCX specifications)
