Description

METHOD AND SYSTEM FOR AUTOMATICALLY MONITORING A NETWORKFIELD OF THE DISCLOSURE

[0001] The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for automatic network monitoring and network structure probing i.e., automatically monitoring a network.BACKGROUND

[0002] The following description of 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 be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of 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. 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 the context of 5G networks, probing plays a crucial role in ensuring the robustness and efficiency of the network infrastructure. With the advent of 5G technology, which introduces new capabilities such as ultra-low latency, high bandwidth, and massive connectivity, the need for sophisticated probing techniques becomes paramount. Network operators and administrators rely on probing mechanisms to continuously monitor and analyse various aspects of 5G networks, including signal strength, latency, packet loss, and Quality of Service (QoS) metrics. Probingenables them to identify potential bottlenecks, optimize network performance, and troubleshoot issues promptly, thereby ensuring seamless delivery of high-speed, low-latency services to endusers.

[0005] Moreover, in the dynamic and complex environment of 5G networks, probing also serves as a vital tool for security and risk management. With the proliferation of loT devices, edge computing, and mission-critical applications in 5G ecosystems, the attack surface and potential vulnerabilities increase significantly. Probing techniques such as vulnerability scanning, intrusion detection, and traffic analysis help detect and mitigate security threats, unauthorized access attempts, and malicious activities in real-time. By proactively probing the network for security risks and anomalies, organizations can enhance their cyber defence posture and safeguard sensitive data.

[0006] Further, traditional network monitoring and network structure probing methods have long faced challenges due to the limitations imposed by physical taps, aggregators, and packet capturing tools. Physical taps, which involve physically accessing and tapping into network cables, often require significant effort and resources. They can disrupt network connectivity and pose risks of damage or interference to the network infrastructure. Similarly, aggregators, which are used to collect network traffic from multiple sources, face limitations in terms of scalability and flexibility. They can struggle to handle large volumes of network data, leading to potential data loss or delays in capturing critical information. Additionally, aggregators may not provide granular visibility into specific network segments or devices, limiting their effectiveness in complex network environments. Further, the packet capturing tools, although commonly used for network monitoring, also present challenges. They typically require deep packet inspection and analysis, which can be time-consuming and resource intensive. Furthermore, encrypted traffic poses a significant hurdle for traditional packet capturing tools, as they are unable to decipher encrypted content, limiting their ability to provide comprehensive insights. These challenges have led to the development of alternative approaches and technologies in network monitoring and structure probing. For instance, software-defined networking (SDN) and network functions virtualization (NFV) have emerged as solutions that offer greater flexibility, scalability, and visibility. They enable centralized management and control of network resources, allowing for efficient monitoring and probing without the need for physical access.

[0007] In addition to the benefits they offer, the adoption of software-defined networking(SDN) and network functions virtualization (NFV) also brings certain drawbacks. One significantchallenge is the complexity associated with implementing these technologies. Transitioning from traditional networking infrastructures to SDN and NFV architectures requires substantial expertise and resources, making the migration process intricate and demanding. Moreover, virtualizing network functions may introduce performance concerns, as virtualized components may not always match the performance levels of dedicated hardware solutions. This performance overhead can impact the overall efficiency and reliability of the network. Furthermore, SDN and NFV architectures pose new security risks, including vulnerabilities in virtualized network elements and potential threats associated with centralized control functions.

[0008] Therefore, since the currently available network monitoring and structure probing methods have faced challenges with physical taps, aggregators, and packet capturing tools, the evolving landscape of network technologies and further the currently available solutions have high capital and operational expenditures (CAPEX and OPEX) even for ingesting a small amount of data.Thus, there exists an imperative need in the art for automatic network monitoring and network structure probing.OBJECTS OF THE DISCLOSURE

[0050] As portable electronic devices and wireless technologies continue to improve and grow in popularity, the advancing wireless technologies for data transfer are also expected to evolve andreplace the older generations of technologies. In the field of wireless data communications, the dynamic advancement of various generations of cellular technology are also seen. The development, in this respect, has been incremental in the order of second generation (2G), third generation (3G), fourth generation (4G), and now fifth generation (5G), and more such generations are expected to continue in the forthcoming time.

[0051] Radio Access Technology (RAT) refers to the technology used by mobile devices / user equipment (UE) to connect to a cellular network. It refers to the specific protocol and standards that govern the way devices communicate with base stations, which are responsible for providing the wireless connection. Further, each RAT has its own set of protocols and standards for communication, which define the frequency bands, modulation techniques, and other parameters used for transmitting and receiving data. Examples of RATs include GSM (Global System for Mobile Communications), CDMA (Code Division Multiple Access), UMTS (Universal Mobile Telecommunications System), LTE (Long-Term Evolution), and 5G. The choice of RAT depends on a variety of factors, including the network infrastructure, the available spectrum, and the mobile device's / device's capabilities. Mobile devices often support multiple RATs, allowing them to connect to different types of networks and provide optimal performance based on the available network resources.

[0052] As discussed in the background section, that in 5G network, probing is essential for maintaining network robustness and efficiency. With 5G's advanced capabilities like ultra-low latency and high bandwidth, sophisticated probing techniques are crucial for continuous monitoring and analysis. Network operators rely on probing to assess signal strength, latency, packet loss, and Quality of Service metrics, enabling them to identify bottlenecks, optimize performance, and troubleshoot issues promptly. Additionally, in the dynamic 5G environment, probing serves as a vital tool for security and risk management. However, the current known solutions for automatic network monitoring network structure probing have several shortcomings such as physical taps, aggregators, and packet capturing tools which involve physically accessing and tapping into network cables, which often require significant effort and resources for network monitoring network structure probing .

[0053] The present disclosure aims to address the aforementioned and other existing issues in this field of technology by introducing a novel solution involving the implementation of a probing agent within the combo-core network nodes. This probing agent is responsible for collecting probing data, referred to as Streaming Data Records (SDRs), whenever an error or network anomaly occurs within the network functions (NFs). The NFs generate these SDRs, including clearcodes, at the procedure level. Furthermore, the SDRs, along with the clear code, may be transmitted by the solution proposed in the present disclosure for further analysis by an operator. The collected SDRs are subsequently indexed by the artificial intelligence / machine learning unit, enabling further analysis that aids in network monitoring, troubleshooting, and root cause analysis.
