LG U+ Achieves 99% Network-Configuration-Data Consistency, Reduces Operational Costs, and Provides Real-Time Network Information

LG U+ provides cell phone, international phone, internet phone, and IP TV services, as well as Web cards and photo technologies to more than 10 million subscribers in the Republic of Korea. It was formed in 2010 from three communication companies, LG Telecom, LG Dacom, and LG Powercom, with the aim of building the world’s first 100 megabytes-per-second internet protocol (IP) fixed-line and wireless network. Its objective is to become a market leader in 4G technologies and increase customer satisfaction by offering new smart services that aren’t limited by traditional telecommunications networks.

In 2011, LG U+ established the Republic of Korea’s most extensive wireless network and launched its 4G long-term evolution (LTE) network. The company needed an integrated, flexible network resource management system (NRMS) and operations support system (OSS) to support its increasing complex telecommunications network infrastructure.

LG U+ implemented Oracle Communications Unified Inventory Management, Oracle Communications Network Discovery, and Oracle Communications Network Integrity Reconciliation Manager to manage its system and equipment network configuration data, more efficiently, operate and maintain its network resources, and gain a competitive edge in the telecommunications market. It has reduced the risk of network failure; lowered repair, maintenance, and operational costs; and increased the rate of consistency between various LTE data configuration to around 99%.

 
Achieving 4G Network Goals with a New NRMS

A word from LG U+ Corp.

  • “We selected Oracle Communications applications for our network resource management system, based on superior support, functionality, maintenance, and cost-effectiveness. We have improved the accuracy and consistency of our network configuration data to 99%, reduced maintenance and operational costs, and met our goal to become a market leader in 4G LTE technologies.” – Han Yeong-geun, Team Leader, NMS Technology Team, NW Technology, LG U+ Corp.

To achieve its “Beyond Telecom” goal to provide 4G LTE network services across the Republic of Korea and become a market leader in next-generation technologies, LG U+ needed an integrated NRMS and a flexible OSS that would improve the accuracy and consistency of network configuration data, and adapt to rapidly evolving network equipment and environments.

“We needed to replace multiple, inefficient, in-house systems with a fast, intuitive, and self-managed NRMS and OSS,” said Han Yeong-geun, team leader, NMS technology team, NW technology, LG U+ Corp. “The previous systems required duplicate, time-consuming, and error-prone manual data entry processes. Network administrators struggled to quickly detect inaccurate or inconsistent data, and correctly identify errors in network equipment. This led to engineers being dispatched to troubleshoot problems unnecessarily.

“We wanted to reduce the time needed to detect and correct inaccuracies and standardize network equipment inventory and configuration information across the country to ensure maintenance and repairs were carried out correctly,” he said. “We also needed to launch the 4G LTE and all-IP fixed-line and wireless networks as quickly as possible.”

LG U+ developed its NRMS using Oracle Communications Network Integrity Reconciliation Manager and Oracle Communications Network Discovery. The NRMS is integrated with an element management system (used to manage network equipment and operating systems) and a network management system (used to monitor the wireless network). The NRMS accurately monitors and manages network configuration data, such as physical cell identity data (used to identify the location of cell phones, synchronize channels, and transmit data) and root sequence index (used to set up calls).

The company also implemented Oracle Communications Unified Inventory Management to underpin a flexible, integrated OSS that can quickly respond to business expansion and the evolution of the network and new smart services.

Why Oracle

After completing detailed industry analysis and evaluating several products, LG U+ selected Oracle Communications applications based on their functionality, maintenance, and cost-effectiveness. The Oracle products provided superior support and features for a number of LG U+’s services and business processes, including IPTV, cell phone, broadband, order management, and service activation.

“We chose Oracle because the flexible communication applications enable us to quickly respond to business expansion by supporting a standards-based developmental approach and integrating disparate systems,” said Han. “It also fully supports the standard shared-data modeling that is promoted by the world’s largest industrial standardization body, the TM Forum.”

LG U+ was also attracted by the system implementation support offered by Oracle Consulting, including workshops and training sessions.

Implementation Process

LG U+ engaged Oracle Consulting to help it deploy Oracle Communications Unified Inventory Management 7.0, Oracle Communications Network Discovery 7.0, and Oracle Communications Network Integrity Reconciliation Manager 7.0 in April 2011. The first phase of the NRMS began in July 2011 and went live in March 2012.

In December 2011, LG U+ engaged Oracle Partner ABACUS to upgrade the system with Oracle Communications Unified Inventory Management 7.1, Oracle Communications Network Discovery 7.1, and Oracle Communications Network Integrity Reconciliation Manager 7.1. The new NRMS went live in May 2012.

Advice from LG U+
To implement a network resource management system quickly and efficiently, you need to define the scope of the system and equipment before you start, as carrying out modeling tasks after the system implementation can create difficulties.

The right network is the basis of a telecommunication companies’ competitive strength, so the project needs to be conducted with long-term goals rather than short-term benefits in mind. It also requires great support and efforts from executives and technical staff.

Partner

During the upgrade, ABACUS developed functionalities for modeling and Web service development. It also helped with system porting tasks, including new server porting and data conversion.

“Thanks to ABACUS’s swift and accurate technical and operational support, we’ve deployed an NRMS to integrate our fixed-line and wireless networks and help us lead the 4G LTE market,” said Kim Tae-ho, section leader, NMS technology team, NW technology, LG U+ Corp. “In the future, we’ll continue our partnership to grow together and set benchmarks for network management systems.”
