SK Telecom announced today that it has successfully developed an advanced public safety network for first responders that works on the 4G LTE network. Working in partnership with Nokia, the Operator launched a portable all-in-one Public Safety-LTE (PS-LTE) network system that leverages Network Functions Virtualization (NFV) technology.
A public safety network is a wireless communications network used by emergency services organizations such as police, fire and emergency medical services, to prevent or respond to incidents that harm or endanger persons or property.
Although compact enough to fit into a backpack, the system is equipped with all elements required for mobile telecommunications including a base station (eNB), switching system (core network: Evolved Packet Core, Home Subscriber Server, Policy and Charging Rules Function, etc.) and Push To Talk (PTT) technologies – to instantly create an independent communications network to be used by public safety workers/emergency services.
The network deployed with the system provides coverage of five kilometers and accommodates up to 400 users, and has a set-up time of less than three minutes.
Both companies are also working to enhance the system using a real-time Group Communication System Enabler (GCSE) which is based on mobile evolved Multimedia Broadcast Multicast Service (eMBMS).
