PEE Control and Monitoring

Description

PEECMON, or PEE Control and Monitoring, is a standardized management function defined in 3GPP specifications, primarily in TS 28.305. It operates within the broader context of network management systems, focusing specifically on the Power and Energy Efficiency (PEE) domain. The architecture of PEECMON involves management entities that interface with network elements, such as base stations and core network nodes, to collect energy-related data and enforce energy-saving policies. These entities typically include a Network Management (NM) system that hosts the PEECMON functionality, which communicates with Element Management (EM) systems or directly with Network Functions (NFs) using standardized interfaces like the Itf-N or service-based interfaces in 5G.

In operation, PEECMON works by defining a set of managed objects, performance measurements, and fault management parameters related to energy consumption. It collects data on power usage, energy efficiency metrics (e.g., bits per joule), and environmental factors (e.g., temperature) from network equipment. This data is then processed to monitor energy performance, detect anomalies, and generate reports. PEECMON also supports control functions, such as activating or deactivating energy-saving features (e.g., sleep modes in base stations) based on network load or operator policies. Key components include the PEE Management Service (PEE-MS), which provides the core capabilities, and associated information models that standardize how energy data is represented and exchanged.

PEECMON's role in the network is critical for enabling energy-aware operations. It integrates with other management functions, like Performance Management (PM) and Fault Management (FM), to provide a holistic view of network performance and efficiency. By standardizing energy management, PEECMON allows operators to implement consistent energy-saving strategies across multi-vendor networks, ensuring interoperability. It supports use cases like dynamic power scaling, where network resources are adjusted based on traffic patterns to reduce energy consumption without compromising service quality. Furthermore, PEECMON facilitates compliance with regulatory requirements and sustainability initiatives by providing verifiable energy efficiency reports.

Purpose & Motivation

PEECMON was created to address the growing need for energy efficiency in mobile networks, driven by increasing energy costs, environmental concerns, and the expansion of network infrastructure (e.g., with 5G deployments). Prior to its standardization, energy management was often vendor-specific, lacking interoperability and consistent metrics, making it difficult for operators to optimize energy usage across diverse equipment. The limitations of previous approaches included fragmented management interfaces, inadequate reporting capabilities, and no unified way to control energy-saving features, leading to suboptimal energy performance and higher operational expenses.

The motivation for PEECMON stems from 3GPP's focus on sustainability and operational efficiency, particularly as networks scale to support higher data rates and more devices. By introducing a standardized framework for PEE control and monitoring, 3GPP enables operators to reduce their carbon footprint and lower energy costs. Historically, energy management was handled ad-hoc or through proprietary solutions, but with PEECMON, it becomes an integral part of network management, aligning with global efforts like the UN Sustainable Development Goals. It solves problems such as inconsistent energy measurement, lack of control over energy-saving mechanisms, and difficulty in benchmarking efficiency across network segments.

PEECMON also addresses the technical challenges of modern networks, where energy consumption is a significant factor in total cost of ownership (TCO). For instance, in 5G networks with massive MIMO and dense deployments, energy usage can escalate rapidly. PEECMON provides the tools to monitor and mitigate this, supporting features like network slicing with energy-aware resource allocation. By standardizing in Release 15 and evolving through subsequent releases, it ensures that energy management keeps pace with network advancements, enabling smarter, greener operations.
