METHOD AND SYSTEM FOR PROACTIVE ENERGY OPTIMIZATION IN A CELLULAR NETWORKFIELD OF INVENTION
[0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to methods and systems for proactive energy optimization in a cellular network.BACKGROUND
[0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.
[0003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. The third generation (3G) technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users.
[0004] In wireless communication technologies, it is important to optimize the energy of cells and therefore several solutions have been developed for energy optimization. Existing solutions often rely on reactive mechanisms and include triggering sleep modes based on observed low traffic conditions, wherein in a sleep mode one or more functionalities of a cell or a radio unit of a cellular network are turned off or disabled for a specific time period. These reactive approaches of theexisting solutions can lead to inefficiencies and latency in network performance, as they must wait for low usage periods to trigger energy-saving modes (i.e., sleep modes).
[0005] Conventional energy-saving techniques frequently use fixed thresholds or timers to transition between active and sleep states. In the active state (or active mode) the one or more functionalities of a cell or a radio unit of a cellular network is turned on or enabled. This fixed thresholds or timers-based transition between active and sleep states can lead to sub-optimal energy savings, as these thresholds / timers may not adapt to dynamic network conditions and traffic patterns. Further, the energy-saving modes in existing arts typically lack granularity. They often offer a binary choice between a fully active state and a sleep state, without considering intermediate stages that could offer more balanced energy savings and performance. Currently known techniques fail to efficiently and effectively identify the most appropriate times to activate or deactivate sleep modes, potentially leading to inefficient use of resources. Moreover, the prior solutions may not be adequately adaptable to changes in network conditions, such as fluctuations in network load, varying Quality of Service (QoS) requirements, or changing user behaviour patterns. This lack of adaptability could lead to energy wastage and reduced network performance.
[0006] Thus, there exists an imperative need in the art for a technical solution that aims to address at least the above-mentioned technical issues by managing an energy consumption in cellular networks in an efficient and effective manner.SUMMARY

[0074] Referring to Figure 1A and Figure IB that illustrates an exemplary block diagram of a RAN management layer
[0158] and the RAN layer
[0114] , the RAN management layer
[0158] (i.e., Intelligent Platform / NRT-RIC Layer
[0102] and the Network Management Layer
[0106] ) collects data for monitoring the performance of the one or more cell sites and implement one or more sleep modes. The performance monitoring includes monitoring at least the one or more current or past traffic levels, and the predicted one or more traffic levels, a coverage map, etc. For model training, the RAN management layer
[0158] utilizes the AI / ML techniques for effective and efficient functioning of the RAN management layer
[0158] , For predictive analysis, the RAN management layer
[0158] utilizes the historic data associated with one or more traffic levels at the one or more cell sites in the past. The RAN management layer
[0158] is responsible for triggering the one or more sleep modes, if the predefined thresholds for the one or more traffic levels is satisfied by the selected cell site. For instance, Figure 1A depicts that if for a monitoring period a Threshold T1>LTS threshold (long-term statistical threshold,), then the RAN management layer
[0158] will trigger the RU Hibernation mode and Figure IB depicts that if for a monitoring period say Ml the T1<LTS as, then the RAN management layer
[0158] will trigger advanced sleep mode.
[0075] Further it is also depicted in the Figure 1 A that once the RU Hibernation mode is triggered then after waiting for a reactivation timer (RTh), a reactivation process starts (by notifying a central controller), activating the RU's radio resources, and enabling the transmit / receive functions. The configuration and state of the reactivated RU are then restored.
[0076] Also, it is depicted in the Figure IB that once the advanced sleep mode is triggered then in case of any configuration update, new user identification, and / or incoming signal detection, a reactivation procedure is activated, and normal operations are resumed after reactivation from the advanced sleep mode.
[0077] Also, the RAN management layer
[0158] is responsible for performing the functions, as illustrated in the Figure 1A and Figure IB, such as data collection, performance monitoring (predicted traffic level, actual traffic level and coverage map), predictive analysis, parameter optimization, scenario identification, managing AI / ML techniques, model training, data aggregation, and configuration management, etc.
[0078] Further referring to Figure 2, an exemplary block diagram of a system
[0200] for proactive energy optimization in a cellular network, is shown, in accordance with the exemplary implementations of the present disclosure. The system
[0200] comprises at least one monitoring unit
[0202] , at least one predicting unit
[0204] , at least one identifying unit
[0206] and at least one processing unit
[0208] , Also, all of the components / units of the system
[0200] are assumed to be connected to each other unless otherwise indicated below. Also, in Figure 2 only a few units are shown, however, the system
[0200] may comprise multiple such units or the system
[0200] may comprise any such numbers of said units, as required to implement the features of the present disclosure. The system
[0200] may reside in a server or a network entity.
[0079] The system
[0200] is configured for proactive energy optimization in the cellular network, with the help of the interconnection between the components / units of the system
[0200] ,
[0080] Particularly, for proactive energy optimization in the cellular network initially the monitoring unit
[0202] is configured to monitor a network traffic load associated with a plurality of cells of the cellular network. The cellular network is a radio network that is distributed over land areas called cells. Further, in the cellular network each cell uses a different set frequency from its neighbouring cell to avoid interference and provide guaranteed bandwidth within each cell. Further, the network traffic load comprises but not limited to at least one of a data transmission volume, a user activity, and one or more resource utilization metrics within the cellular network. In an implementation the monitoring unit
[0202] works in conjunction with the Non-Real Time Radio Intelligent Controller (NRT-RIC) layer
[0102] , The NRT-RIC layer
[0102] is a part of a network architecture that collects and processes data about network traffic and performance. The monitoring unit
[0202] collects data concerning various aspects of a network traffic and aperformance, such as the number of active users, a data throughput, a signal strength, and one or more quality of service. Once the data is collected, the data is then processed to provide a comprehensive view of the network's current state and performance. The processed data includes information like the areas of high traffic density, periods of peak usage, and points of congestion or weak signal strength.
[0081] Once the monitoring unit
[0202] monitors the network traffic load, the predicting unit
[0204] is configured to predict, using a trained model, a traffic pattern for at least one cell of the plurality of cells based on the monitored network traffic load. Further, the traffic pattern corresponds to a forecast period of a low activity and a potential for an energy saving. The forecast period of low activity includes the time period during which the traffic on the one or more cells is low or there is almost no activity on the one or more cells. Further, the low activity on the one or more cells provides that there is potential or possibility of saving energy on the one or more cells. The trained model is one of a Support Vector Machine (SVM), and a neural network. Further, the model is trained based on a dataset comprising a historical network performance data and a corresponding traffic load pattern observed within the cellular network. Furthermore, the SVM is a model based on the machine learning that uses supervised learning algorithm to solve complex classification and regression problems. Further, the neural network is a machine learning program that mimics the human brain i.e., it makes decision in a manner similar to the human brain. Further, the prediction unit
[0204] considers the historical data and current trends to forecast the likely demand on the network resources.
[0082] Further, the identifying unit
[0206] is configured to identify one or more radio units (RUs) for transitioning into one or more sleep modes based on the predicted traffic pattern. The one or more sleep modes are selected from a group comprising of a remote unit (RU) Hibernation mode, a Deep Sleep mode, a Light Sleep mode, an Uplink (UL) Transmission Only mode, and a Downlink (DL) Transmission Only mode. Further, the one or more sleep modes pertain to one or more levels of one or more energy-saving techniques without causing one or more service interruptions in the at least one cell. Also, the RU Hibernation is energy-saving feature in cellular networks such as 5G that allows Radio Units (RUs) to enter a hibernation mode during extended periods of no traffic for longer period of time. By completely shutting down the RU and conserving power, RU Hibernation significantly reduces energy consumption and contributes to overall energy savings in the network. Further, the Deep Sleep refers to a power-saving mode where the radio unit is temporarily deactivated or put into a low-power state when there is no traffic or minimal traffic. By entering deep sleep, the RU significantly reduces its power consumption,resulting in energy savings without impacting network performance. Further, the Light Sleep is a power-saving mode where the radio unit operates in a low-power state while remaining active to quickly respond to incoming traffic. This mode allows the RU to conserve energy while maintaining the ability to quickly resume normal operations when needed. Further, the UL (Uplink) Only Transmission is an energy-saving feature that enables the radio unit to transmit data only in the uplink direction, while suspending or reducing downlink transmissions. This mode is beneficial when the network experiences asymmetric traffic, allowing efficient resource utilization and power optimization. The Downlink (DL) Transmission Only mode is an energy-saving feature that enables the radio unit to transmit data only in the downlink direction, while suspending or reducing uplink transmissions.
[0083] Once the identifying unit
[0206] identifies one or more radio units for transitioning, the processing unit
[0208] is configured to initiate at least one of the one or more sleep modes for the identified one or more RUs to optimize power consumption. The processing unit
[0208] is further configured to quantify an energy saving achieved by the at least one of the one or more sleep modes by mapping a power utilization to a physical resource block (PRB) usage. PRBs are units of resources in the cellular networks such as a 5G network, and this mapping allows the system
[0200] to directly tie energy savings to network performance. The PRBs are fundamental components of the cellular networks that represent a chunk of frequency and time used for data transmission. By correlating power utilization to PRB usage, the system
[0200] can estimate the amount of power saved during the sleep period. The energy savings measurement provides a concrete metric that can be used to evaluate the efficiency of the sleep mode implementation. This energy saving metric reflects the trade-off between network performance and energy consumption. It can also guide future decisions regarding the power management of the network, as it offers insights into the impact of different energy-saving strategies. This way, the system not only optimizes power usage but also provides a quantitative measure to evaluate the effectiveness of energy-saving interventions in the network.
[0084] Also, processing unit

Predefined triggers may include a time schedule, a specific network events, or a threshold level of network demand. This functionality ensures that the system
[0200] can swiftly respond to any upsurge in network demand. As a result, it strikes a balance between energy optimization and maintaining a high quality of service. Therefore, the reactivation of the one or more RUs from the one or more sleep modes is particularly important during peakusage times or when a significant load is expected on the network, such as during a major event or during certain times of the day.
[0085] The predicting unit
[0204] is further configured to predict one or more coverage holes within the cellular network based on the one or more RUs being in the at least one of the one or more sleep modes. Coverage holes are areas where client devices cannot receive a signal from the wireless network. Coverage holes are caused due to physical obstructions such as walls, buildings, etc. Further, the processing unit
[0208] is configured to utilize one or more neighbour cells for balancing the network traffic load and maintaining coverage during the one or more sleep modes. Once the predicting unit
[0204] predicts the coverage holes, the processing unit
[0208] utilizes the neighbouring cells and transfers the load from the one or more cells to the other cells in the cellular network for balancing the load and to provide proper network connectivity to the users. The processing unit
[0208] further provides a neighbour management profile based on at least one of a geographical location and a handover (HO) count for each of the one or more sleep modes for each of the one or more RUs, to facilitate in managing neighbour relationship and provide a list of targeted neighbours for a coverage hole analysis and a load balancing.
[0086] The processing unit

[0206] is further configured to identify a power emergency with the one or more cells, the power emergency comprises at least one of a low battery and an operating on diesel generator. Further, the processing unit
[0208] is configured to activate the one or more sleep modes based on the identified power emergency.
[0088] Moreover, the system
