Description

METHOD AND SYSTEM FOR PROACTIVE INTERFERENCE MANAGEMENT IN A TELECOMMUNICATION NETWORK

FIELD OF INVENTION

The present invention relates generally to the field of wireless communication systems. More particularly, the present invention relates to methods and systems for proactive interference management in a telecommunication network.

BACKGROUND

The following description of related art is intended to provide background information pertaining to the field of the invention. This section may include certain aspects of the art that may be related to various features of the present invention. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present invention, and not as admissions of prior art.

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. 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.

Despite the significant advancements in 5G technology, operators and service providers still face challenges in its implementation. One notable issue is tropospheric interference, which continues to pose a significant obstacle. The tropospheric interference is a major critical area for all operators as it gives major impact during the weather changes due to the tropospheric duct and that too for a very long distance up to 1000km. The tropospheric interference occurs when a Global Navigation Satellite Systems (GNSS) signal passes through troposphere which is a closest atmosphere to the Earth’s surface. Also, the troposphere may cause a delay in the GNSS signal, that results in atiming error. Further, this type of interference is particularly prevalent in regions with high humidity, such as near coastlines, and especially during adverse weather conditions, such as heavy rain or snow.

There was a need in the state of the art to predict the tropospheric interference so that measures can be taken to rectify issues caused by such interference. Over the period of time, various solutions have been developed to improve the performance of communication devices and to perform interference management in telecommunication network. However, there are certain challenges with existing solutions. The existing solutions for interference predictions in a network, in near real time lacks the precision, moreover the existing solutions fails to optimize a network performance as the existing solutions fails to provide a robust reliable communication infrastructure that can meet the evolving demands of modem telecommunications hence there is a scope of further advancement.

Thus, there exists an imperative need in the art to perform proactive interference management in telecommunication network.

For ease of reference, FIG. 2A depicts units/components of the system [200] by way of representation of blocks and FIG. 2A do not represent the internal circuitry or connections of each component/unit of the system [200], It will be appreciated by those skilled in the art that disclosure of such drawings/block diagrams includes disclosure of electrical components and connections between said electronic components, and electronic components or circuitry commonly used to implement such components.

Further, in accordance with the present disclosure, it is to be acknowledged that the functionality described for the various the components/units can be implemented interchangeably. While specific embodiments may disclose a particular functionality of these units for clarity, it is recognized that various configurations and combinations thereof are within the scope of the disclosure. The functionality of specific units as disclosed in the disclosure should not be construed as limiting the scope of the present disclosure. Consequently, alternative arrangements and substitutions of units, provided they achieve the intended functionality described herein, are considered to be encompassed within the scope of the present disclosure.

Additionally, the processing unit [204], the determination unit [206], the filtering unit [208], the image extraction unit [210], the visual representation unit [212] and the prediction unit [214] are processors. The processor may be a general-purpose processor, a special purpose processor, a conventional processor, a digital signal processor, a plurality of microprocessors, one or more microprocessors in association with a DSP (digital signal processor) core, a controller, a microcontroller, Application Specific Integrated Circuits, Field Programmable Gate Array circuits, any other type of integrated circuits, etc. Also, the transceiver unit [202] includes a transmitter having capabilities to transmit data/signals and optionally also a receiver unit having capabilities to receive data/signals.

The system [200] is configured to perform proactive interference management in a telecommunication network, such as the 5G network depicted in Fig. 1.

In order to provide proactive interference management in the telecommunication network, the transceiver unit [202] is configured to receive a historical interference data on a periodic basis (for e.g., last 30 days). The historical interference data is the data associated with one or more cells in the telecommunication network and the historical interference data is a record of past instances of interference within the telecommunication network. Further the historical interference data may include a plurality of data such as timestamps, interference type, severity, location, etc. Additionally, the historical interference data is received in the periodic basis which is pre-set by an operator or administrator of the system [200] . The historical interference data may be received from a storage unit [216] that is connected with the transceiver unit [202],

Upon receiving the historical interference data, the processing unit [204] which is connected at least with the transceiver unit [202], processes the historical interference data to identify a preexisting set of aggressor cells (i.e., interference causing cells) and a corresponding set of victim cells (i.e. interference experiencing cells), based at least on a set of parameters.

The present disclosure encompasses that the set of parameters comprises at least one of distance of the set of pre-existing aggressor cells from the corresponding set of victim cells; and a confidence level threshold. The confidence level threshold may refer to a measure of certainty or reliability applied to the identification of pre-existing aggressor cells and corresponding victim cells based on historical interference data.

Upon identification of the pre-existing set of aggressor cells and the corresponding set of victim cells, the determination unit [206] which is connected at least with the processing unit [204], determines an interference score corresponding to each pre-existing aggressor cell of the existing set of aggressor cells.

The present disclosure encompasses that the interference score is determined based at least on a count of a set of victim cells associated with each of the set of pre-existing aggressor cells and interference consistency caused for at least a second pre-defined time period. The second predefined time period is pre-set by the operator or administrator of the system [200],

The present disclosure encompasses that the interference score refers to severity and further indicates the number of cells impacted by the set of pre-existing aggressor cells within a specific timeframe.

For example, in a telecommunication network having a plurality of cells, the processing unit [204] identifies count of cells, such as 5 cells as pre-existing aggressor cells which indicates that these cells may cause interference to the say 10 nearby cells which are corresponding set of victim cells. Further, the determination unit [206] analyses this count of 10 victim cells to calculate the interference score for each of the 5 pre-existing aggressor cells.

Further, upon determination of the interference score, the filtering unit [208] which is connected at least with the determination unit [206], filters a set of consistent aggressor cells (i.e. consistently causing interference) and corresponding set of victim cells from the pre-existing set of aggressor cells based at least on a configuration and the determined interference score.

The present disclosure encompasses that the filtering of the set of consistent aggressor cells is done on the basis of reporting by the set of victim cells for a particular time period. For example, in a time period of 7 days, the victim cell is reported another cell as the aggressor cell daily.

The set of consistent aggressor cells refers to a set of cells that consistently cause interference to nearby cells over a period of time which may be identified based on historical data as regularly and persistently causing interference to other cells within the telecommunications network.

The configuration refers to a file that includes at least one of the specific settings and the parameters that may be used by the filtering unit [208] to determine which aggressor cells and corresponding victim cells shall be filtered from the pre-existing set of aggressor cells based on their interference score. Additionally, the configuration file may include instructions or rules that are pre-defined by the operator. Furthermore, the configuration file may comprise a data related to time period such as one or more days, one or more months and alike. Also, the configuration file may include data related to a count of victim cells for each aggressor cells. For instance, the configuration file may include a set of rules and a set of thresholds to identify or filter the set of consistent aggressor cells (i.e., consistently causing interference cells) and corresponding set of victim cells from the pre-existing set of aggressor cells.

For example, the filtering unit [208] may filter out a top severity set of consistent aggressor cells (for instance consistent in last 7 days) and the corresponding set of victim cells from the preexisting set of aggressor cells (for instance from last 7 days) based at least on a configuration file and the determined interference score.

Upon filtration, the image extraction unit [210] that is connected at least with the filtering unit [208], extracts a set of images from a map depicting forecast for a tropospheric ducting for a first pre-defined time period. For example, the image extraction unit [210] extracts a set of images from the map, based on a fixed training dataset, a set of top consistent values, a set of aggregators, and a set of data, depicting the forecast for tropospheric ducting for the next day (i.e., the first predefined time period). The first pre-defined time period refers to a pre-defined timer period set by the operator or any administrator. The set of data may include open-source data related to forecasting of the tropospheric ducting, for e.g., Hepburn data.

The set of images refers to one or more geographic images from the map that represents forecast for tropospheric ducting for pre-defined time period. The tropospheric ducting is a type of radio propagation that permits a transmission of very high frequencies (VHF) and above beyond a standard line of sight range.

The forecasting of tropospheric ducting involves a multifaceted approach that are known to person in the skilled and integrates various meteorological data sources, numerical weather prediction models, empirical models, remote sensing techniques, and specialized software. A meteorological data from weather stations, satellites, and weather balloons provides essential information on atmospheric parameters such as pressure, temperature, humidity, wind speed, and direction. Numerical weather prediction models simulate the behaviour of the atmosphere, predicting future conditions that may lead to tropospheric ducting events. Empirical models leverage historical data to identify patterns and correlations between atmospheric conditions and ducting occurrences. Remote sensing techniques, including radar and satellite imagery, offer real-time insights into atmospheric dynamics that influence ducting phenomena. Specialized software tools are developed to integrate and analyse these diverse data sources, enabling the creation of accurate and timely forecasts of tropospheric ducting behaviour. Thereafter, the visual representation unit [212] that is connected at least with the image extraction unit [210], overlays the set of consistent aggressor cells and the corresponding set of victim cells on the extracted set of images to create a visual representation, for proactive interference management in a telecommunication network.

Further, overlay refers to a technique for transposing the image or text over each other. The overlay may be done via one or more image overlaying techniques which may be known to person skilled in the art. Moreover, in the present disclosure the visual representation unit [212] uses the one or more image overlaying techniques to combine the extracted set of images with the set of consistent aggressor cells and the corresponding set of victim cells for producing a clear and informative visual representation of the interference dynamics within the telecommunication network.

The present disclosure encompasses that the system [200] further comprises of a prediction unit [214] configured to predict, using a trained model, a set of candidate aggressor cells and a corresponding set of victim cells based at least on processing of the visual representation received by the visual representation unit [212],

The trained model refers to a pre-trained model that is a machine learning (ML) model which has been trained on a large dataset and may be fine-tuned for a specific task. The large dataset may relate to interference in the telecommunication network. Further, the trained model may be trained on an open source data such as Hepburn data, fixed training dataset [200e] and a set of consistent aggressors [200d].

Further, in addition to this, the processing unit [204] is configured to perform a down-tilting of the predicted set of candidate aggressor cells and the corresponding set of victim cells by utilizing an Upper Side Lobe Suppression (USLS).

The down-tilting refers to a technique of adjusting a direction or a focus of the predicted set of candidate aggressor cells in downward direction that may reduce interference or improve signal reception in specific regions. Further, in the telecommunication architecture, a side lobe is a secondary lobe of radiation that occur alongside the main lobe in in antenna patterns and USLS refers to a technique or mechanism used to suppress or reduce these upper side lobes which ultimately reduces interference from one or more unwanted directions.

Referring to FIG. 2B, exemplary implementation of the system for proactive interference management in a telecommunication network is shown, in accordance with the exemplary embodiments of the present disclosure. The historical interference data on the periodic basis is received from the transceiver unit [202] . As shown in FIG. 2B, the historical interference data may be interference raw data [200a] , which is further utilized by a consistent aggressor processor [200b] and a fixed training data set processor [200c] . The consistent aggressor processor [200b] is similar to the processing unit [204], the determination unit [206], the filtering unit [208] of FIG. 2A. The consistent aggressor processor [200b] produces a set of consistent aggressors [200d] and the fixed training data set processor [200c] generates a fixed training data set [200e] . Thereafter, the set of consistent aggressors [200d] and the fixed training data set [200e] along with a data [200j] is forwarded to a training data extractor [200f] . Further, the training data extractor [200f] generates a training data which is provided to a model generator [200g] to generate a model [200h] which is further operated on a simulator [200i] to produce a set of predicted aggressors [200k] .

For instance, the interference raw data [200a] is processed on a daily basis to filter out a set of prominent aggressors based on distance and confidence levels. Subsequently, the fixed training data is prepared based on the last 30 days, comprising sets of aggressors and victims. Furthermore, the severity of consistent aggressors is determined using a score (i.e., interference score), calculated through consistency in the last 30 days, consistency in the last 7 days, and the count of victims. Following this, a number of top severity consistent aggressors, based on the configuration file, are filtered out. Next, a set of images from map plotted data is processed. The map plotted data provides a forecast of tropospheric ducting for the next days. Finally, the filtered top severity consistent aggressors and their corresponding victims are mapped over the tropospheric interference duct image obtained from the plotted map to derive a set of predicted aggressors and victim pairs.

Referring to FIG. 3, an exemplary method [300] for proactive interference management in telecommunication network, in accordance with exemplary embodiments of the present disclosure is shown. In an implementation the method [300] is performed by the system [200], As shown in FIG. 3, the method [300] starts at step [302],

At step [304] , the method of the present disclosure comprises receiving, by a transceiver unit [202] , a historical interference data on a periodic basis (for e.g., last 30 days).

The historical interference data is a record of past instances of interference within the telecommunication network. Further the historical interference data may include a plurality of data such as timestamps, interference type, severity, location. Additionally, the historical interference data is received in the periodic basis which is pre-set by an operator or administrator of the system [200],

Further the present disclosure encompasses that the historical interference data may be received from a storage unit [216],

The method then proceed to next step [306], in which the method of the present disclosure comprises processing, by a processing unit [204], the historical interference data to identify a preexisting set of aggressor cells (i.e., interference causing cells) and a corresponding set of victim cells (i.e. interference experiencing cells), based at least on a set of parameters.

Upon identification of the pre-existing set of aggressor cells and the corresponding set of victim cells, the method then proceed to step [308], in which the method of the present disclosure comprises determining, by a determination unit [206], an interference score corresponding to each pre-existing aggressor cell of the existing set of aggressor cells.

The present disclosure encompasses that the interference score is determined based at least on a count of a set of victim cells associated with each of the set of pre-existing aggressor cells and interference consistency caused for at least a second pre-defined time period. The second predefined time period is pre-set by the operator. For example, in a telecommunication network having a plurality of cells, the processing unit [204] identifies 5 cells as pre-existing aggressor cells which indicates that these 5 cells may cause interference to the say 10 nearby cells which are corresponding set of victim cells. Further, the determination unit [206] analyses this count of 10 victim cells to calculate the interference score for each of the 5 pre-existing aggressor cell.

Further, upon determination of the interference score, the method proceeds to step [310], in which the method of the present disclosure comprises filtering, by a filtering unit [208], a set of consistent aggressor cells and a corresponding set of victim cells from the pre-existing set of aggressor cells based at least on a configuration file and the determined interference score.

The configuration file refers to a file that includes at least one of the specific settings and the parameters that may be used by the filtering unit [208] to determine which aggressor cells and corresponding victim cells shall be filtered from the pre-existing set of aggressor cells based on their interference score. Additionally, the configuration file may include instructions or rules that are pre-defined by the operator. For instance, the configuration file may include a set of rules and a set of thresholds to identify or filter the set of consistent aggressor cells (i.e., consistently causing interference cells) and corresponding set of victim cells from the pre-existing set of aggressor cells.

Upon filtration, the method proceeds to step [312] in in which the method of the present disclosure comprises extracting, by an image extraction unit [210], a set of images from a map depicting a forecast for a tropospheric ducting for a first pre-defined time period. For example, the image extraction unit [210] extracts a set of images from the map, based on a fixed training dataset, a set of top consistent values, a set of aggregators, and a set of data, depicting the forecast for tropospheric ducting for the next day (i.e., the first pre-defined time period). The first pre-defined time period refers to a pre-defined timer period set by the operator or any administrator.

Thereafter, at step [314], the method of the present disclosure comprises overlaying, by a visual representation unit [212], the set of consistent aggressor cells and the corresponding set of victim cells on the extracted set of images to create a visual representation, for proactive interference management in a telecommunication network.

The present disclosure encompasses that the method further comprising predicting, by the prediction unit [214] using a trained model, a set of candidate aggressor cells and the corresponding set of victim cells based at least on processing of the visual representation.

The trained model refers to a pre-trained model that is a machine learning (ML) model which has been trained on a large dataset and may be fine-tuned for a specific task. The large dataset may relate to interference in the telecommunication network.

The present disclosure encompasses that the method further comprising performing, by the processing unit [204], down-tilting of the predicted set of candidate aggressor cells and the corresponding set of victim cells utilizing an Upper Side Lobe Suppression (USLS).
