SK Telecom, Nokia Develop Ready-to-Use Portable Public Safety-LTE (PS-LTE) Network System

The Korean telecommunications service provider SK Telecom and Nokia has developed a portable all-in-one Public Safety-LTE (PS-LTE) network system for emergency responders. The developers claim it to be the world’s first portable all-in-one PS-LTE network based on Network Functions Virtualization (NFV) technologies.

The advanced PS-LTE system, shaped in the form of a rectangle and compact enough to fit into a backpack, comprises 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, thus can be used instantly.

The existing portable LTE systems are only composed of a base station and hence, they need to be connected to a backhaul network to enable communications.

Commenting on the new portable PS-LTE system, Lee Jong-bong, Executive Vice President and Head of Infra Division of SK Telecom said, “The portable all-in-one PS-LTE system is a ground-breaking solution that enables communication among first responders by setting up an independent LTE network when regular communication networks are disrupted by disasters.”

Using the portable PS-LTE system, the responders can communicate each other, can add communication add-ons such as group messaging, user management programs, etc. It provides a coverage of 5kms and is capable of connecting up to 400 users. The connections can be set-up in less than three minutes, stated SK Telecom in a release.

The portable PS-LTE system will be released for the trial this year and SK Telecom targets to utilize it to expand the national disaster safety wireless network and ‘LTE for Maritime Wireless Communications (LTE-Maritime)’ project in 2017.

“SK Telecom will not only utilize the innovative system to build disaster safety wireless networks in Korea but also plans to share its expertise and know-how with many other countries around the world,” Lee Jong-bong said.

“We are very pleased to customize our all-in-one Ultra Compact Network in cooperation with SK Telecom and local small and medium-sized enterprises to suit their individual needs. Nokia will continue to take the lead in PS-LTE related standardization activities by collaborating with Korean companies and offering advanced PS-LTE solutions to our customers,” commented Andrew Cope, head of Korea at Nokia.

SK Telecom and Nokia is together working on diverse disaster communication technologies since 2015.
