LG Uplus Accelerates 5G Network Era with VoLTE Virtualization

Published2017.05.16 16:53

LG Uplus is accelerating preparations for network virtualization to evolve into 5G.

LG Uplus announced that it has accommodated VoLTE (voice calls using the LTE network) services by applying NFV, a virtualization technology, to its core data processing communication equipment, the 'SPGW (Serving Packet data network Gateway).'

Network Function Virtualization (NFV) is a next-generation network technology that separates the operation of hardware and software in communication equipment and enables the virtualization and execution of various software on a general-purpose hardware platform.

Communication equipment equipped with NFV requires lower investment and operating costs than existing hardware equipment, and enables the implementation of various software-based functions. Following the application of NFV technology to carrier-grade routers that establish information transmission paths in the network last year, LG Uplus has incorporated VoLTE services into data by applying this technology this year to SPGW, a core communication device that performs VoLTE, data processing, speed control, and packet billing.

With the application of NFV technology to SPGW equipment, each device that previously operated as separate hardware is now operated on a large-capacity server, allowing for the rapid application of various functions, such as future 5G services, with just a simple software installation.

As SPGW is a sensitive device responsible for voice call services such as VoLTE and general data processing, even when NFV-applied equipment is applied to actual commercial networks, it has mainly accommodated data services and only limitedly accommodated VoLTE services.

LG Uplus has been using NF in its commercial VoLTE network since 2015.After making various efforts, such as applying V technology and conducting interoperability tests, it has become possible to stably accommodate not only the virtualization of SPGW equipment but also VoLTE after about two years.

"SPGW virtualization is a core technology that enables the rapid application of various data-based services to 5G networks," said Jeong Hyeong-rok, Head of Network Development at LG Uplus. "We will virtualize various communication equipment early to prepare for the 5G network era one step ahead."

SalePoint Signs Multi-Year Partnership Agreement with AWS… Promoting Identity Security that Integrates Even AI Agents

Sailpoint has entered into a multi-year strategic partnership agreement with AWS and is moving forward with establishing an integrated governance system that manages both human and non-human identities together. The plan is to consistently manage access permissions in an environment where AI agents are increasing as work execution entities, while applying the principle of least privilege and automated policy enforcement. The two companies plan to jointly expand capabilities to manage the identities of various entities, including AI agents, within a single layer in the AWS environment. This collaboration is interpreted as a move to design security and governance together in corporate environments where AI adoption is expanding.
