Mobile Train Radio Communication - LTE

The base station for LTE radio, responsible for transmitting and receiving radio signals to and from user equipment (UEs) in one or more cells. It's connected to other network components via S1 and X2 interfaces.

A network component in the Evolved Packet Core (EPC) responsible for handling the user plane, which carries actual data traffic between user devices and external networks.

A network component in the EPC that connects to the external IP networks and handles user traffic between the EPC and those networks.

A network component in the EPC that manages the control plane of the network, handling signaling for mobility and security.

A database that holds user and subscriber information for an LTE network.

The ability of a network to handle a large number of users simultaneously, especially in a cell or a specific area.

The E-UTRAN is designed for low mobile speeds, ideal for pedestrians and vehicles in urban environments.

The network supports high performance for users moving at higher speeds, ensuring seamless connectivity for vehicles and other fast-moving entities.

The E-UTRAN is designed to maintain connectivity for users traveling at speeds exceeding 120 km/h, facilitating smooth transitions for high-speed travel.

The range of a cell, influenced by factors like required throughput at the edge of the cell, available bandwidth, and the desired mobility.

MBMS allows for simultaneous broadcast and multicast services, enabling efficient delivery of content to multiple users.

E-UTRAN coexists with older technologies like GERAN and UTRAN, allowing for seamless transitions between network generations.

E-UTRAN prioritizes a packet-based architecture for efficient data transfer, although it can support real-time and conversational traffic.

A system that delivers announcements to passengers throughout the station, including concourses and platforms. This can broadcast both live and pre-recorded information.

Allows users within a station or depot to communicate with each other using voice.

Enables communication between different systems on the same train or across multiple trains. It also facilitates data exchange between train systems and ground-based systems.

Allows data communication between railway infrastructure systems and ground-based control systems. This data is used for various purposes, such as demand forecasting, equipment monitoring, and response planning.

A ground-based system can initiate data communication with specific train systems to remotely control certain functions. This is a crucial aspect of train operations.

Allows data communication between non-critical infrastructure systems and railway staff or ground-based/on-board systems for remote monitoring and control.

This application allows for the transmission of real-time video images from cameras for non-critical railway operations. It also enables control of camera movements and zoom features.

Provides train staff with access to intranet/internet services via a wireless connection within the train.

The ability for users to send and receive various types of non-critical messages, like text, voice recordings, images, and videos. These messages can be exchanged between individual users or with multiple recipients.

Transferring recorded data after an incident for analysis purposes. This data could be from CCTV cameras, JRU (Joint Rail Unit) systems, or energy meters. It allows for investigation and understanding of what happened.

The capability to record and broadcast audio or video information to specific users based on their identity and location. This allows for targeted communication within the system.

The ability to move large amounts of CCTV footage between train systems or between trains and a ground station. This allows for efficient transfer of security data for monitoring and analysis.

Setting up real-time video calls between users on the train system. Enables visual communication for various purposes like coordination and assistance.

A system where information is overlaid on a user's live video stream, creating an augmented reality experience. This lets ground controllers provide information and guidance to users within the train system.

Allowing members of the public to initiate voice communication with ground staff or train personnel. This provides a means for passengers to ask questions or request information.

A system where members of the public can initiate emergency voice communication that automatically routes to the most appropriate personnel, like ground staff, train staff, or the driver. This ensures efficient emergency response.

Ensuring that voice communication links are monitored for activity or breaks. The system alerts users accordingly.

Controlling the number of people speaking during a group call. Designated users can decide who's allowed to talk.

Managing user identities and tracking their presence within specific contexts (like train, region, or groups). Users can see who else is available.

Storing and retrieving the locations of users and devices within the system. This feature helps track users and devices in the system.

Controlling access to voice and data communication based on user identities. This helps secure communication channels.

Controlling access to applications based on various factors like user identity, location, or group membership. This ensures proper application access.

Setting different communication quality levels for applications based on their needs. This ensures optimal communication quality for different tasks.

Ensuring the authenticity and integrity of messages received by onboard applications. This helps detect message tampering or corruption.

Allows a user to invite others to participate in a live voice communication, enabling a group chat.

The system's ability to prioritize and handle multiple incoming communication requests, preventing overload.

Provides billing information for network usage, helping users track and pay for communications.

A high-speed LTE network used for reliable train-to-ground and train-to-train communication, improving passenger safety and security.

Emergency communication systems between trains, control centers, and stations to ensure rapid response in critical situations.

Modern signaling systems that allow more trains to operate on a given track without compromising safety, increasing carrying capacity on existing infrastructure.

Live surveillance cameras on trains for passenger security and crime prevention, using video analytics.

Staff communication systems and remote monitoring of railway assets for improved efficiency and reliability.
