DS-6310 DMR Simulcast System
The Hytera DMR Simulcast System (DS-6310) is developed on the basis of the Digital Mobile Radio (DMR) Tier II standard. It follows principles such as simultaneous broadcasting, large coverage, and smooth analog-to-digital migration. This system is designed to meet the requirements of users needing an easy-to-set-up, easy-to-use, and reliable communication network covering a wide area with a single pair of frequencies.
Architecture
The Hytera DMR simulcast system comprises an MSO (Mobile Switching Office), Base Stations, a Dispatch System, NMS (Network Management System), Service Terminals, and a Bearer Network. One MSO can support up to 100 Base Stations or 200 carriers. A single DMR simulcast Base Station can support up to 2 carriers.
Diagram Description: Network Architecture
A satellite is shown communicating with multiple Base Stations (BS). Each BS is connected via a Router to a Bearer Network, which is described as IP/E1.wireless. The Bearer Network also connects to a Firewall, LDS, Central Control Server, Core Switch, NMS Server, and a Wireless Dispatch System. A Core Router is also depicted.
DS-6310 Base Station Overview
Diagram Description: DS-6310 Base Station (Single Carrier BS, 8U)
The front panel of the base station shows four numbered components: 1. Built-in Router, 2. Synchronized Expansion Unit, 3. Transceiver (RD98XS), and 4. Power Unit & Duplexer.
- Compact design, high integration, easy for delivery and deployment.
- Module structure for faster maintenance and modules replacement.
Key Features
Higher Spectrum Efficiency
Diagram Description: TDMA Spectrum Efficiency
Illustrates how DMR's two-slot TDMA technique allows two simultaneous communications on a single 12.5 kHz radio channel. It shows two time slots (slot1, slot2) per channel, supporting DMR Radio 1, Radio 2, Radio 3, and Radio 4. A base station antenna is also depicted.
- Simulcast technique reduces the need to a single pair of frequencies (one for TX and one for RX), regardless of the number of Base Stations in the network.
- DMR two-slot TDMA technique supports 2 simultaneous communications on a single 12.5 kHz radio channel.
Smooth Roaming and Handover
Diagram Description: Roaming and Handover
Depicts three Base Stations (BS1, BS2, BS3) operating on frequency f1, connected to a central system (implied by satellite symbol). This illustrates how a radio can seamlessly roam and handover between different Base Stations, ensuring continuous communication.
- In a simulcast system, the radio is capable of roaming and handover seamlessly between different BSs; ongoing communication continues normally during handover.
Dynamic Voting
- Simulcast systems provide good voice performance in overlap areas, as radios can always receive the best voice frame through dynamic voting.
- The MSO acts as a voting center, analyzing each voice frame received from Base Stations in real-time to extract and send the best voice frame to radios.
Flexible Networking
- The IP-based architecture enables flexible networking.
- Multiple transmission links can be used between BS and MSO, such as IP, E1, Microwave, or wireless bridge.
- Standard SIP and RTP are used to interconnect with other systems like PSTN systems and DMR trunking systems.
Analog/Digital Self-adaptive
Diagram Description: System Configurations
Three diagrams illustrate different system setups: Analog Simulcast System, Dual-mode Simulcast System, and DMR Simulcast System. Each shows Base Stations (BS), MSO, and terminals (Analog Terminal or DMR Terminal) connected via frequency f1.
- Simulcast Base Station channels support working in both analog and digital modes, ensuring smooth migration from analog to digital networks.
- Digital or analog mode is automatically selected based on incoming signals.
Smart Subnetting and Patching
Diagram Description: Subnetting and Base Station Configuration
Illustrates four subnets (Subnet 1, 2, 3, 4) with specific RD98XS units assigned to slots and channels (e.g., RD98XS1-Slot1). Below, a DMR Simulcast Base Station configuration is shown with RD98XS units connected via frequency f1.
- According to management requirements, the DMR simulcast system can be divided into different subnets by Base Station or by time slot of channel unit in each Base Station. Each subnet can function as an independent simulcast system.
- Different subnets can be patched to create a larger subnet temporarily, as needed.
Dedicated GPS Channel
- A dedicated GPS channel can be used in the DMR simulcast Base Station to increase GPS data transmission capability.
Versatile Services
- Voice services: individual call, group call, all call, emergency call, broadcast call, dispatcher call, PSTN call, etc.
- Data services: text message, status message, emergency alert, GPS data polling, AVL (Automatic Vehicle Location), etc.
- Advanced services: end-to-end encryption, late entry, discreet listening, voice recording, etc.
Long Time GPS Holdover
- In case of GPS failure, the Base Station supports a holdover of 48 hours via its internal synchronization reference, ensuring the simulcast service remains normal.
Open API
- An Open API is available for further service development, such as dispatch services, network management services, and GIS services.
Network Management System
Diagram Description: Network Management System (NMS)
A client-server architecture diagram showing multiple client terminals connected to a central server. A network topology map is displayed, illustrating system management capabilities.
The network management system consists of servers and clients, designed to remotely manage and control the simulcast system.
- Various management capabilities: system configuration management, fault management, security management, topology management, etc.
- Supports SNMP.
- Adopts a Client/Server (C/S) structure to support multi-user operation.
- Provides API for further development.
Dispatching System
The dispatching system is designed for efficient communication, management, and dispatching of professional users within the Hytera DMR simulcast system. Hytera offers both wireless and wired dispatch systems.
- Voice Service: Individual call, group call, broadcast call, emergency call, etc.
- Data Service: Text message, status message, GPS Polling, and emergency alert.
- Automatic Vehicle Location (AVL):
- Supports multiple maps (Google Maps or MapInfo).
- Provides terminal location real-time tracking & display.
- Includes track playback functionality.
- Features geo-fencing capabilities.
- Other Service: Stun/revive, voice recording, subnet patching, E2E encryption, etc.
