- 该系统现覆盖约450列火车和约1,000台设备，使用VoLTE实现“零停机”。
- 此次升级保留了必要的铁路专用通信功能（紧急/停车呼叫、调度、编号标准），同时为即将到来的基于4G/5G的通信标准（如FRMCS）做好准备。
事件：瑞士国家铁路运营商SBB与爱立信合作，部署了一项里程碑式升级
瑞士国家铁路运营商SBB与爱立信合作，部署了一项里程碑式升级：将传统铁路通信标准GSM-R与现代IP多媒体子系统（IMS）平台互通，提供基于LTE的语音（VoLTE）。
SBB原本依赖GSM-R进行铁路专用通信，并在GSM-R覆盖不足时依靠Swisscom的公共3G网络进行漫游。如今，SBB面临一个硬性期限——Swisscom计划在2025年底前完全关闭其3G服务。 另见: Ziggo集团任命领导人，备战2027年阿姆斯特丹上市.
为避免任何中断，SBB没有简单地扩展旧的GSM-R基础设施，而是构建了一个融合的IMS/VoLTE解决方案，该方案保留了所有安全关键和铁路专用功能（如紧急停车呼叫、EIRENE编号适配、调度员通信和组呼），同时将语音服务迁移到4G。
部署始于2023年中，随后进行了内部测试、实验室验证，并于2025年1月开始使用试点列车进行现场测试。到2025年4月，系统已在全国推广。截至2025年12月，约450列火车和1,000台运营设备使用VoLTE，实现了零停机。 另见: Alejandro Estua.
爱立信称，这次整合是欧洲首个大规模GSM-R/IMS互通的实际案例，并表明这是一条通往未来铁路通信系统的可行路径。 另见: 亚历杭德罗·曼佐.

为何重要
SBB和爱立信的这一举措解决了与即将到来的3G关闭相关的几个关键挑战：确保铁路网络的不间断、安全关键语音和数据通信，避免依赖即将退役的网络，并建立了其他欧洲铁路运营商可效仿的模型。 另见: 亚历杭德罗·埃尔南德斯.
通过IMS/VoLTE解决方案保留GSM-R的所有铁路专用功能——紧急停车呼叫、特定编号、调度员和组呼——此次升级表明，铁路级通信可以迁移到基于IP的网络，而不会牺牲安全性或可靠性。 另见: 亚历杭德罗·加尔萨.
此外，该项目为未来采用预计依赖5G的FRMCS标准奠定了基础。此类迁移的早期成功可能会鼓励其他地区更广泛地接受类似转型。 另见: Alejandro Guerrero.
然而，该举措也引发了一些问题。例如： 另见: Alec Gramont.
- VoLTE/IMS基础设施能否保持与专用GSM-R相同的韧性和安全水平，尤其是在极端条件或高负载下？
- 对于规模更大或网络更复杂的其他铁路运营商，迁移过程是否同样顺利？
- 是否会因此产生对商业移动网络运营商的非预期依赖——这可能重新引入专用铁路系统旨在避免的脆弱性？
鉴于这据报道是欧洲首个此类整合，唯有时间能证明VoLTE-over-IMS将成为事实标准，还是在通往全面FRMCS采用道路上的权宜之计。 另见: AI芯片通胀：设备制造商受挤压，影响超越数据中心.
