Network Consolidation Challenges After MNO-1 & MNO-2 Merger and Strategy for Operational Excellence in Indonesia Using DIAMON

Post-merger between MNO-1 and MNO-2 become new entity 'MNO-M', there are some obligations from government: It is required to make a frequency band return of 2 × 5 MHz at 2.1 GHz, adding new sites for services until 2025, and to improve its Quality of Service (QoS). On top of those obligations, during the network consolidation, there are some challenges such as big network infrastructure complexity from MNO-1 & MNO-2, network consolidation must be done on the live network which potentially impact to customer experience, and many 3G sites which require to be sunset as part of government compliance. The method that is used in this paper is by analysis secondary data from MNO-M and review of scientific literature as supporting reference. The strategy to be able to face the challenges by building a platform and tool that will provide end-to-end visibility to multi-operator networks. This paper introduces a new digital operation concept and solution named DIAMON (Digital Intelligence Automation Multi-Operator Network). DIAMON integrates all of Network Elements (NEs) multi-vendor end-to-end and provides full visibility for network operations management (network monitoring, performance management, service quality, and customer experience management). A strong digital operation platform and tool through DIAMON is also very important to support the multi-operator network to face network consolidation challenges and provide excellence operational services in Indonesia.
