OverviewSolution Overview
Huawei Mass Transit eLTE Multiple Service and Unified Bearer Solution uses the Enterprise Long-Term Evolution (eLTE) network for multimedia trunking, Passenger Information System (PIS), Closed-Circuit Television (CCTV), and Communication-Based Train Control System (CBTC) services instead of using traditional WLAN and TETRA train-to-ground wireless communications networks.
Multimedia trunking: provides voice dispatching and commands, dispatching of production instructions (data + voice), device data collection, industry user device/site video surveillance, and on-site video backhaul.
PIS: provides video collection, processing, and play control as well as system management. Onboard video provides passengers information services such as train arrivals, departures, and delays.
CBTC: guarantees train controls that report train locations in real time and perform train completeness tests.
Huawei Mass Transit eLTE Multiple Service Unified Bearer Solution V100R001C00 implements PIS and CCTV services through the eLTE train-to-ground wireless communications network. CBTC and multimedia trunking service will be implemented in later versions.

Test Roadmap
Huaweis Mass Transit eLTE Multiple-Service Unified Bearer Solution V100R001C00 transports eLTE-based PIS and CCTV services. In the actual test process, there is a lack of PIS and CCTV system materials. Use test tools to simulate service data flows based on corresponding service models. The entire integration test is divided into a static test inside labs and a high-speed travel test outside the lab.
1) The static test inside labs focuses on network performance indicators such as basic broadband access functions, end-to-end latency, packet loss, QoS, inter-cell switching, and reliability. This test reveals potential risks, ensuring proper eLTE-based PIS and CCTV services in static situations.
2) The high-speed travel test deploys eLTE wireless coverage on roadsides. It uses vehicles mounted with PIS and CCTV service terminals in place of trains to perform high-speed, dynamic vehicle tests, and verifies the feasibility of eLTE-based PIS and CCTV services at high speeds.
Product line managers shall select models and perform test acceptance for subsolutions involving a single type of product, a single type of purchased parts, or a single product line. For specifications and features, see the attachment, eLTE3.1 Product Specifications. This solution provides no detailed verification.

Networking description:
1) T6020 and IPCLK3000 work in active/standby mode. Hop-by-hop time synchronization is performed on the entire network. OSN3500 uses IEEE 1588v2 to provide clock synchronization for base stations.
2) Control center devices include a PIS multicast server, LTE core network eCNS210, and eOMC Network Management System (NMS), multicast video, video surveillance, data management, dispatching management, and LTE wireless network management.
3) Base stations are divided into Baseband Units (BBUs) and Remote Radio Units (RRUs) for wireless transmission.
4) Terminals include the TAU600, which is used as a data terminal to access onboard data and video information.
