Public safety is one of the core responsibilities of any government, and involves an overarching goal of protecting citizens from threats such as crime and natural disasters. This typically involves coordination between various organizations including police, firefighters and emergency medical services. When a threat occurs, it is critical that relevant organizations are able to rapidly communicate with one another. This means that availability of a converged communication network dedicated to public safety agencies should be ensured with a seamless and reliable communication path always assured.

Public Safety Powered by LTE

One of the biggest advantages of public safety-LTE (PS-LTE) networks is data connectivity. While previous public safety networks could only relay voice, PS-LTE can transfer high volumes of data instantly. This means that high quality images and video can be sent enabling the use of various applications such as live streaming during emergency situations or mapping software for locating or directing mission-critical assets or concerns.

LTE can also be leveraged to unify existing disparate public safety networks. Before, disaster response institutions utilized different frequencies and technologies such as VHF, UHF and TETRA. With so many different networks, inter-agency communication was difficult. Faster response can be achieved when these different networks are unified through LTE. Another advantage is that LTE networks satisfy the rigorous requirements set out for public safety networks such as resilience, security and quality of service.

Samsung is the world’s first end-to-end provider of Public Safety LTE(PS-LTE) and has actively participated in the establishment of global PS-LTE standards.

Samsung utilizes its latest technologies to provide the world’s first virtualized PS-LTE core system, which supports over 400,000 simultaneous users, while combining several critical LTE functions into a unified element in order to maximize system efficiency and reduce both deployment and continuous operational costs.

Samsung is incorporating our very best technologies and services into a dedicated PS-LTE solution in order to provide one of the most advanced PS-LTE solutions across the globe.

Samsung is at the forefront of the development of LTE standards, ranking first in standard essential patents related to LTE and LTE-Advanced in the industry for two consecutive years. In this regard, Samsung ranks at the top of 35 major telecommunication businesses.

This leadership and drive for innovation is well-applied to PS-LTE with Samsung contributing greatly to the 3GPP’s Release 13 standards for PS-LTE. One of the features Samsung most actively participated in defining as well as one of the most important features of PS-LTE is the Mission Critical Push-to-Talk (MCPTT) feature. This function enables thousands of devices to be connected at once to transfer video, images and voice simultaneously using multicast technology. This feature is so critical to enabling a truly superior public safety service that the 3GPP established a separate working group (Service and System Aspects, WG 6 – Mission Critical Applications) devoted to defining such standards, with the full support of Samsung who currently chairs the group.

When an emergency occurs on a large scale (such as an earth quake or tsunami), several thousand emergency services personnel may need to be simultaneously coordinated, and providing reliable and accurate communications between devices is essential for handling the associated challenges in a rapid and effective manner.

For example, a typical unicast communications service is only capable of supporting a small number of users in a given location. When sending a large amount of content, including HD voice, video or high resolution images, with limited cell capacity, Samsung’s PTT solution leverages eMBMS broadcast technology in order to transmit data to up to several thousand users within range of a given LTE base station.

This method allows extremely rapid information n during crisis situations, without bogging down the network.

The IP Multimedia Subsystem (IMS) is a 3GPP standard base platform for hosting and delivering applications and services to users on a mobile network.

Such multimedia services include voice service over LTE (VoLTE), PTT solution as well as Mission Critical Push-to-Talk(MCPTT) solution. More importantly, new and advanced services expressly designed to enhance communication and coordination of emergency services personnel can be easily developed and deployed to any given PS-LTE network, providing additional upgrade opportunities.

During many extreme natural weather events, such as earthquakes and floods, communication networks often suffer outages due to damaged or otherwise disabled equipment. While the PS-LTE network enjoys the same rapid re-deployment capabilities as any other LTE network, Samsung’s solution also supports direct device-to-device communications, to ensure that services personnel can remain in contact with one another at all times, regardless of network status.

Developed in cooperation with Korean operators, the same technology that drives D2D communications can also be used to identify and locate nearby survivors at the site of an emergency. This technology provides important enhancement to the effectiveness of search and rescue operations, and aims to significantly reduce loss of life in crisis situations.
