[0026] 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.

[0027] In modern telecommunication networks, various types of network equipment play crucial roles in ensuring efficient and reliable communication. Among these, radio frequency (RF) equipment is particularly important for wireless communications. One key component of this RF equipment is the remote radio head (RRH). An RRH is a remote radio transceiver that connects to a radio base station unit via an electrical or wireless interface. The RRH includes the base station's Radio Frequency (RF) circuitry, analog-to-digital or digital-to-analog converters, up / down converters, and other essential components. RRHs have operation and management processing capabilities and a standardized optical interface to connect to the rest of the base station. As one of the two primary units of a wireless base station, the RRH functions as the RF processing unit that transmits and receives signals. RRHs are typically placed at base stations and mounted near antennas, where they receive, transmit, filter, and amplify RF signals. Radio nodes within the network comprise RRHs that perform various network operations.

[0028] Network optimization often requires the relocation of RRHs from underutilized areas to overutilized zones. For instance, if a high-capacity RRH is present in an area with minimal traffic, network operators need to move this RRH to a zone experiencing higher traffic demands. This process of swapping RRHs from one location to another on radio nodes is crucial for optimal network management, involving regular transfers between low-capacity and high-capacity zones.

[0029] The conventional process of RRH swapping involves multiple teams and complex coordination. An on-site team physically visits the site to remove and replace the RRH unit. This team switches off the site, removes the old RRH unit, and installs a new one. However, this process is fraught with inefficiencies and challenges. Multiple action items must be performed to reactivate the site and resume routine customer traffic. The backend team, responsible for configuration and upkeep, must wait for instructions from the on-site team after the physical swapis completed. This dependency between teams often leads to delays and inefficiencies in the swapping process.

[0030] Furthermore, the current approach lacks automation and centralized management. Each swap requires manual intervention at multiple stages, from initial planning to final integration testing. This manual process is time-consuming, prone to errors, and lacks scalability, especially when dealing with multiple sites or different types of radio nodes with varying software versions.

[0031] The absence of a streamlined, automated system for managing RRH swaps across multiple network sites poses significant challenges. Network operators struggle with coordinating between on-site and backend teams, ensuring proper pre-swap checks, managing post-swap integrations, and maintaining network optimization across diverse radio nodes. The lack of a centralized platform for workorder management, configuration retrieval, and integration testing further complicates the process.

[0032] Conventional systems and methods face difficulty in efficiently managing large-scale RRH swaps, coordinating between multiple teams, ensuring proper integration of swapped equipment, and maintaining network optimization across diverse radio nodes. There is, therefore, a need in the art to provide a method and a system that can overcome the shortcomings of the existing prior arts. The present invention aims to address these challenges by providing an automated, centralized solution for managing network equipment swaps, particularly RRH swaps, across multiple nodes in a telecommunication network.

[0033] It is therefore an objective of the present invention to provide a system and method for efficiently managing and executing network equipment swaps across multiple nodes, automating pre-swap checks and post-swap integration tests, and improving coordination between on-site and backend teams,thereby overcoming the above-mentioned disadvantages in the field of network equipment management and optimization.SUMMARY OF THE DISCLOSURE

[0081] The word “exemplary” and / or “demonstrative” is used herein to mean serving as an example, instance, or illustration. For the avoidance of doubt, the subject matter disclosed herein is not limited by such examples. In addition, any aspect or design described herein as “exemplary” and / or “demonstrative” is not necessarily to be construed as preferred or advantageous over other aspects or designs, nor is it meant to preclude equivalent exemplary structures and techniques known to those of ordinary skill in the art. Furthermore, to the extent that the terms “includes,” “has,” “contains,” and other similar words are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising” as an open transition word without precluding any additional or other elements.

Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0083] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

[0084] The aspects of the present disclosure are directed to a system and a method for performing network equipment swaps, particularly remote radio head (RRH) swaps, across a plurality of nodes in a network parallelly. The system and method aim to automate and optimize the swap process by coordinating activities between on-site and backend teams, executing pre-swap checks, and performing post-swap integration tests to ensure efficient and reliable network equipment upgrades.

[0085] To perform network equipment swaps such as RRH swapping, an on-site team visits the network site to physically remove and replace the equipment.The on-site team switches off the site, removes the existing RRH unit, and installs a new RRH unit into the radio node. However, multiple activities are required to reactivate the site and resume routine customer traffic. The backend team waits for instructions from the on-site team that has physically removed the old equipment and installed the new equipment. The on-site team then informs the backend team to perform backend configurations and maintenance. After swapping the RRH unit, upgrades are performed on the new RRH unit. This process creates a dependency between the two teams, necessitating the need for various preparatory actions before the on-site team begins its work.

[0086] The present disclosure addresses these challenges by providing a system for performing network equipment swaps across a plurality of nodes in a network. The system includes a user interface module, a services module, and an application server module that work in conjunction to synchronize activities between the on-site team and the backend team. For instance, when stopping radiation at the site, the on-site team may not have the authority or access to do so. The backend team, using the system, can stop the site before the on-site team arrives. This process of stopping the site, also referred to as locking or unlocking, involves halting site communication and initiating a shutdown of the particular cell.

[0087] The services module performs all pre-swap checks, making runtime decisions for the particular configuration and setting parameters for the site. The application server module applies all dynamically decided configurations to the newly swapped network equipment. Subsequently, the application server module initiates integration tests to verify whether the new equipment has started accepting user traffic and if all operations are normal post-swapping.

[0088] By introducing this automated system, the overall workflow is optimized, improving scalability and efficiency. The system applies various logic to define all parameters based on multiple environmental factors, such as the geography type of the RRH unit, ensuring a more adaptive and context-aware swapprocess across different types of radio nodes with varying software versions in the network.

[0089] The various embodiments throughout the disclosure will be explained in more detail with reference to FIGS. 1-6.

These instructions may include procedures for coordinating activities between onsite and backend teams, executing pre-swap checks, and performing post-swap integration tests.

[0099] In an embodiment, the system (102) may include VO interface(s) (206). The VO interface(s) (206) may comprise a variety of interfaces, for example, interfaces for data input and output devices, storage devices, and the like. The VO interface(s) (206) may facilitate communication through the system (102). The VO interface(s) (206) may also provide a communication pathway for one or more components of the system (102). Examples of such components include, but are not limited to, processing module(s) (208), and one or more databases (210) for storing workorders, configuration parameters, and related data for network equipment swaps.

[0100] The processing module(s) (208) may include a user interface module (212), a services module (214), an application server module (216), and other modules (218). The user interface module (212) may receive workorders comprising lists of network sites where network equipment swaps are to be performed. The services module (214) may execute a set of pre-swap checks on each network site of the list of network sites. The application server module (216) may initiate a series of integration tests to verify implementation of the network equipment swap at the network site.

[0101] The other modules (218) may include additional components that support and enhance the network equipment swap process. These may include a firmware upgrade module for performing firmware upgrades on the swapped equipment, a configuration module for applying dynamically decided configurations to the newly swapped network equipment, a network optimization module for performing network optimizations post-swap, and an integration module for integrating the network site to the network to carry production traffic after successful swap of the network equipment. The other modules (218) may also include a coordination module for synchronizing activities between the on-site team and the backend team, a validation module for validating the received workorder prior to retrieving the set of configuration parameters from the database, and a monitoring module for evaluating results of the series of integration tests and initiating appropriate actions based on the results. These other modules (218) work in conjunction with the main processing modules to ensure comprehensive, efficient, and reliable network equipment swaps across various network conditions and node types.

[0102] In an embodiment, the processing module(s) (208) may be implemented as a combination of hardware and programming to implement one or more functionalities of the processing module(s) (208). For example, the programming for the processing module(s) (208) may be processor-executable instructions stored on a non-transitory machine-readable storage medium and thehardware for the processing module(s) (208) may comprise a processing resource (for example, one or more processors), to execute such instructions. These instructions may include procedures for managing workorders, executing pre- swap checks, coordinating between on-site and backend teams, performing network equipment swaps, and conducting post-swap integration tests.

[0103] Although FIG. 2 shows exemplary components of the system (102), in other embodiments, the system (102) may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 2. For instance, the system may include additional modules for handling specific types of network equipment or for managing swaps across different network technologies.

[0104] The system (102) for performing network equipment swaps across a plurality of nodes in a network comprises a memory (204) and one or more processors (202) coupled to the memory (204). The one or more processors (202) are configured to execute a set of instructions stored in the memory (204) to carry out various operations related to network equipment swaps. Network equipment swaps refer to the process of replacing or upgrading hardware components in a telecommunications network to enhance performance, increase capacity, or introduce new functionality. The network equipment swap may be a remote radio head (RRH) swap.

[0105] In the context of telecommunications networks, network nodes are functional elements or points of communication within the network architecture. These nodes form the backbone of cellular networks and include structures such as cell towers, rooftop installations, and small cell sites. The system (102) is designed to manage equipment swaps across multiple such nodes, which can number in the hundreds or thousands within a cellular operator's network.

[0106] Network equipment swaps often involve the replacement of Remote Radio Heads (RRHs), which are crucial components in cellular network base stations. The RRH processes radio frequency signals between the antenna and the baseband unit, playing a vital role in the network's operation. The need for RRH swaps arises from various factors, such as equipment failures, technology upgrades (for example, transitioning from 4G to 5G), or the necessity to expand network capacity.

[0107] The operations related to network equipment swaps begin with workorder management, where the system creates, validates, and tracks work orders for each swap operation. The processors (202) handle pre-swap preparations, which involve verifying site readiness, confirming the availability of replacement equipment, and coordinating the scheduling of on-site technician visits.

[0108] Configuration management forms another crucial operation performed by the processors (202). This involves retrieving and preparing the correct configuration parameters for the new equipment to be installed. During the actual swap execution, the processors (202) coordinate activities between on-site technicians and remote network management systems. This coordination ensures that the physical swap process aligns seamlessly with the necessary network-level changes.

[0109] Post-swap testing is a critical phase where the processors (202) conduct thorough integration tests. These tests verify that the newly installed equipment functions correctly within the broader network context. The system performs a series of checks to confirm proper integration with existing network elements, signal quality, and overall performance metrics. The series of checks include verifying CPRI link establishment and stability between the new RRH and the baseband unit, measuring key performance indicators such as RSRP, SINR, and throughput rates, and testing handover procedures between the newly swapped cell and neighboring cells. The system also conducts drive tests to assess coverage andcapacity improvements, verifies proper configuration of frequency bands, transmit power levels, and antenna parameters, and checks the integration of the new equipment with the Operations Support System for remote monitoring and management. This comprehensive testing ensures the newly swapped equipment is fully operational and optimized within the network infrastructure.

[0110] The final stage of the swap process involves performance optimization. Here, the processors (202) fine-tune network parameters to maximize the benefits of the new equipment. This optimization process considers factors such as signal strength, coverage area, and data throughput to ensure the network operates at peak efficiency following the equipment swap. The system's network optimization capabilities are a crucial component of its functionality following equipment swaps. The processors execute a comprehensive suite of optimization procedures designed to maximize the performance of newly installed equipment and ensure its seamless integration into the existing network infrastructure. These procedures involve precise adjustments to key network parameters. The system modifies transmission power levels of the swapped equipment to achieve an optimal balance between coverage and interference reduction. It reconfigures frequency allocations to fully utilize the capabilities of the new equipment, enhancing spectral efficiency. The system updates neighbor cell lists to accurately reflect the changed network topology, ensuring proper cell selection and reselection for mobile devices. Handover parameters between the swapped equipment and adjacent cells are recalibrated to maintain smooth transitions for users moving across cell boundaries. Additionally, the system adjusts antenna tilt angles to optimize both coverage area and network capacity. Through these targeted optimizations, the system significantly enhances overall network performance, improves user experience, and ensures efficient utilization of network resources in the wake of equipment upgrades.

[0111] In a practical scenario, the system (102) manages the process of replacing an older 4G RRH with a new 5G-capable RRH. The processors (202)initiate the swap by retrieving a set configuration parameters for the target site from the database (210). The system then guides the on-site technician through the physical swap process, providing step-by-step instructions for powering down the old RRH, disconnecting it, and installing the new unit.

[0112] Once the physical installation is complete, the processors (202) take charge of the remote aspects of the swap. This includes uploading the appropriate firmware and configuration to the new RRH, ensuring it is properly set up for the specific network environment. The system then conducts a series of tests to verify proper integration with the baseband unit and the wider network, checking parameters such as signal quality, data throughput, and network connectivity.

[0113] The system (102) includes a user interface module (212) through which a workorder comprising a list of network sites where network equipment swaps are to be performed is received. The workorder contains details such as site locations, equipment types, and scheduled swap dates. The user interface module (212) provides an interface for users to input, view, and manage workorders efficiently.

[0114] The user interface module (212) may act as the primary interface between human operators and the automated network equipment swap processes. This module presents a user-friendly, web-based interface accessible through standard web browsers, allowing authorized personnel to interact with the system from various locations and devices.

[0115] A workorder, in the context of network equipment swaps, represents a comprehensive document outlining the specific tasks, locations, and timelines for equipment replacement or upgrade operations. Each workorder typically encompasses a list of network sites, forming a cohesive plan for a series of related swap activities. The information contained within the workorder guides both the system's automated processes and the actions of field technicians.

[0116] The list of network sites included in a workorder identifies the specific locations where equipment swaps will occur. These sites may range from large cell towers in urban areas to small cell installations on building rooftops or street furniture. Each site entry in the workorder contains precise location data, which may include GPS coordinates, street addresses, or site-specific identifiers used within the network operator's asset management system.

[0117] Equipment types specified in the workorder refer to the particular hardware components slated for replacement or upgrade. In a telecommunications network, this often involves Remote Radio Heads (RRHs), but may also include other elements such as antennas, power amplifiers, or baseband units. The workorder clearly delineates the current equipment to be removed and the new equipment to be installed at each site, ensuring that field technicians arrive prepared with the correct replacement hardware.

[0118] Scheduled swap timelines may be a crucial part of the workorder, outlining the planned timeline for each equipment swap operation. These dates are carefully coordinated to minimize network disruption and align with broader network upgrade strategies. The scheduling takes into account factors such as peak usage times, availability of technician teams, and dependencies between different swap operations.

[0119] The user interface module (212) facilitates the efficient creation of workorders through intuitive input forms and templates. Users can enter site details, select equipment types from predefined lists, and specify swap dates using interactive calendars. The module may also incorporate features such as bulk upload capabilities for large-scale operations, allowing users to import site lists and equipment details from external spreadsheets or databases.

[0120] Once created, workorders are stored within the database (210) and can be viewed through the user interface module (212). The viewing interface typically presents workorders in a structured format, allowing users to quickly assess the status of planned swap operations. This may include summary views showing overall progress across multiple sites, as well as detailed views for individual locations.

[0121] Management of workorders through the user interface module (212) encompasses a range of functionalities. Users can update workorder details as circumstances change, such as modifying swap dates due to unexpected delays or altering equipment types based on updated network requirements. The module may also provide workflow management features, allowing supervisors to review and approve workorders before they are executed.

[0122] In practice, a network operations manager might use the user interface module (212) to create a workorder for upgrading RRHs across a cluster of 20 cell sites in a metropolitan area. The manager would input the details for each site, specifying the current 4G RRHs to be replaced with new 5G-capable units. The workorder would include the planned swap dates, staggered over a two-week period to allow for efficient use of technician resources.

[0123] Once created, the workorder becomes visible to all relevant team members through the web portal. Field technicians can access site details and equipment specifications, while project managers can track overall progress and make adjustments as needed. The system uses the information from the workorder to automate pre-swap checks, prepare configuration data, and schedule network resources for each site.

[0124] The user interface module (212) thus serves as a central hub for coordinating and managing the complex process of network equipment swaps. By providing a user-friendly interface for workorder creation, viewing, andmanagement, it enables efficient communication and coordination among various teams involved in the swap process, ultimately contributing to smoother and more effective network upgrade operations.

[0125] A database (210) is included in the system (102) to store a set of configuration parameters corresponding to each network site listed in the workorder. The database (210) contains information such as radio node types, radio node configurations, types of Remote Radio Heads (RRHs) installed, and firmware versions of installed RRHs.

[0126] The database (210) acting as a comprehensive storage solution for all network-related configuration data. This centralized repository ensures that all pertinent information required for network equipment swaps is readily accessible and consistently maintained. The database (210) employs data management techniques to organize, store, and retrieve vast amounts of network configuration information efficiently.

[0127] Radio node types stored in the database (210) refer to the specific models and manufacturers of the base station equipment deployed across the network. For example, the database (210) might contain entries for Ericsson RBS 6000 series, Nokia AirScale, or Huawei DBS3900 base stations. Each radio node type has unique characteristics and requirements that influence the swap process, making this information crucial for planning and execution.

[0128] Radio node configurations encompass the specific settings and parameters applied to each node in the network. These configurations may include details such as transmit power levels, frequency bands in use, antenna tilt angles, and cell identifiers. The database (210) maintains a record of these configurations for each site, ensuring that any equipment swaps can be performed while preserving or appropriately modifying these settings.

[0129] The types of Remote Radio Heads (RRHs) installed at each site are also recorded in the database (210). RRHs are crucial components in modern cellular networks, responsible for processing and transmitting radio frequency signals. The database (210) might contain information on various RRH models, such as those supporting different frequency bands (e.g., 700 MHz, 2.5 GHz, 3.5 GHz) or technologies (e.g., 4G LTE, 5G NR). This information is vital for ensuring compatibility when planning equipment swaps.

[0130] Firmware versions of installed RRHs are meticulously tracked within the database (210). Firmware, the software embedded in the RRH hardware, plays a crucial role in the functionality and performance of these devices. The database (210) maintains records of current firmware versions for all installed RRHs, as well as information on available updates. This data is essential for planning firmware upgrades as part of the swap process and ensuring compatibility with other network elements.

[0131] The centralized nature of the database (210) offers significant advantages in the context of network equipment swaps. It provides a single, authoritative source of information, eliminating inconsistencies that might arise from dispersed data storage. This centralization enables swift and accurate retrieval of relevant information for any given network site, streamlining the planning and execution of swap operations.

[0132] In practice, when a network engineer initiates a swap operation for a particular site, the system (102) queries the database (210) to retrieve all relevant configuration data. For instance, if a site in downtown metropolis is scheduled for an RRH upgrade, the database (210) might provide information such as the current node type (e.g., Ericsson RBS 6601), its configuration (e.g., operating on 1800 MHz and 2100 MHz bands), the installed RRH type (e.g., Ericsson Radio 2217), and its firmware version (e.g., R4A01).

[0133] This comprehensive data retrieval allows the system (102) to automatically generate detailed work orders, specifying exactly what equipment needs to be replaced and how the new equipment should be configured. It also enables the system (102) to perform pre-swap compatibility checks, ensuring that the planned new equipment will integrate seamlessly with existing infrastructure.

[0134] The database (210) structure is designed to accommodate the dynamic nature of telecommunications networks. It supports regular updates to reflect changes in the network, such as routine maintenance, equipment failures, or incremental upgrades. This ensures that the information used for planning and executing swaps is always current and accurate.

[0135] Additionally, the database (210) facilitates historical tracking of network configurations. This historical data proves invaluable for troubleshooting, performance analysis, and long-term network planning. It allows network operators to understand the evolution of their infrastructure over time and make informed decisions about future upgrades and expansions.

[0136] By serving as a centralized repository of network configuration data, the database (210) significantly enhances the efficiency and reliability of network equipment swap operations. It provides the foundation for automated processes within the system (102), reducing the potential for human error and enabling rapid, accurate decision-making throughout the swap process.

[0137] The system (102) further comprises a services module (214) configured to execute a set of pre- swap checks on each network site listed in the workorder. These pre-swap checks involve verifying the configuration of the plurality of nodes and a set of parameters for each network site. The set of parameters includes power requirements, physical space constraints, cooling capabilities, and network capacity. For example, the services module (214) might verify that the power supply at a given site is sufficient to support the newequipment, or that the equipment rack has adequate space to accommodate the replacement hardware. The services module (214) performs tasks such as validating network connectivity, checking equipment compatibility, and ensuring all necessary resources are available for the swap operation.

[0138] The services module (214) serving as the primary engine for conducting comprehensive pre-swap assessments. The services module (214) operates under the control of the system, systematically evaluating each network site specified in the workorder to verify readiness for the impending equipment swap. This evaluation process includes checking specific, predefined criteria that are critical for a successful swap operation. For example, the module verifies the current configuration of the site, including equipment types and software versions, against the planned changes. It also checks for any scheduled maintenance or known issues that might interfere with the swap process. Additionally, the module assesses the availability of necessary resources, such as replacement hardware and appropriate technician skills, for each site. By performing these targeted checks, the services module (214) helps identify potential obstacles or incompatibilities before the physical swap begins, allowing for proactive problem-solving and more efficient execution of the swap process. The pre-swap checks conducted by the services module (214) are designed to identify potential issues or incompatibilities before the physical swap process begins, thereby minimizing the risk of complications and reducing network downtime.

[0139] Verification of node configurations forms a fundamental aspect of the pre-swap checks performed by the services module (214). This process involves a thorough examination of the current settings and parameters for each network node scheduled for an equipment swap. The module cross-references the configuration data stored in the database (210) with the actual configuration of the live network elements. This verification ensures that the planned swap is based on accurate and up-to-date information, preventing discrepancies that could lead to integration issues post-swap.

[0140] The set of parameters checked for each network site encompasses a wide range of critical factors that influence the success of the equipment swap. These parameters may include power requirements, physical space constraints, cooling capabilities, and network capacity. For instance, the services module (214) might verify that the power supply at a given site is sufficient to support the new equipment, or that the equipment rack has adequate space to accommodate the replacement hardware.

[0141] Network connectivity validation is a critical task performed by the services module (214). This involves testing the communication links between the network site and the core network infrastructure. The module may conduct ping tests, measure latency, and verify bandwidth availability to ensure that the site has stable and sufficient connectivity. For example, if a Remote Radio Head (RRH) is being swapped, the services module (214) would verify that the fiber optic link between the RRH and the baseband unit is functioning correctly and has the capacity to support the new equipment's data requirements.

[0142] Equipment compatibility checks are another vital function of the services module (214). This process involves analyzing the specifications of the planned replacement equipment against the existing network infrastructure. The module verifies that the new hardware is compatible with other components at the site, such as antennas, power amplifiers, and baseband units. For instance, if a 5G- capable RRH is being installed, the services module (214) would check that the existing antennas can support the required frequency bands and that the baseband unit has the necessary software version to interface with the new RRH.

[0143] Resource availability assessment is a comprehensive check performed by the services module (214) to ensure all necessary components for the swap operation are in place. This includes verifying the availability of replacement hardware, specialized tools, and any required software licenses. The module mayinterface with inventory management systems to confirm that the correct equipment models are in stock and can be dispatched to the site in time for the scheduled swap. Additionally, it may check the availability of skilled technicians with the appropriate certifications to perform the swap.

[0144] In practice, the services module (214) might conduct a pre-swap check for a site scheduled to upgrade from a 4G LTE RRH to a 5G NR RRH. The module would verify the current configuration of the 4G RRH, including its frequency settings, transmit power levels, and cell identifiers. It would then check the compatibility of the planned 5G RRH with the existing antennas and baseband unit. The module would validate the network connectivity to ensure it can support the increased data throughput of 5G. Finally, it would confirm that all necessary hardware, software licenses, and skilled technicians are available for the scheduled swap date.

[0145] The services module (214) generates detailed reports based on these pre-swap checks. These reports highlight any potential issues or discrepancies discovered during the assessment process. For example, if the module detects that the existing power supply is insufficient for the new equipment, it would flag this in the report, allowing planners to arrange for power system upgrades before the swap date.

[0146] By executing these comprehensive pre-swap checks, the services module (214) plays a crucial role in ensuring the smooth execution of network equipment swaps. It provides network operators with valuable insights and advance warning of potential challenges, enabling proactive problem-solving and efficient resource allocation. This systematic approach significantly reduces the risk of unexpected issues during the swap process, minimizing network downtime and ensuring a more seamless transition to the new equipment.

[0147] An application server module (216) is included in the system (102) to receive a completion notification indicating that the network equipment swap has been performed by an on-site team deployed to perform physical equipment changes at a network site from the list of sites. The completion notification is sent through the user interface module (212) or directly to the application server module (216), depending on the system configuration.

[0148] The application server module (216) may be designed to handle critical communications and workflow management related to network equipment swaps. This module acts as the primary recipient of status updates from field operations, particularly the crucial completion notifications that signal the end of physical swap activities at each network site.

[0149] Completion notifications represent formal communications from onsite teams indicating that the physical aspects of the equipment swap have been finalized. These notifications typically include details such as the specific equipment replaced, any challenges encountered during the swap process, and a timestamp of when the swap was completed. For example, a completion notification might state that a Huawei RRH3942 was successfully replaced with an Ericsson AIR 6488 at Site ID 12345 on June 15, 2024, at 14:30 local time.

[0150] The on-site team, responsible for executing the physical equipment changes, plays a crucial role in the swap process. This team typically consists of skilled technicians with expertise in handling telecommunications equipment. Their tasks may include powering down existing equipment, disconnecting cables, removing old hardware, installing new components, reconnecting cables, and performing initial power-up procedures. The completion notification serves as the on-site team's formal declaration that these physical tasks have been accomplished.

[0151] The system configuration, which includes network topology, communication protocols, and user access settings, determines the path throughwhich completion notifications are transmitted to the application server module (216). In some setups, these notifications may be sent through the user interface module (212). This approach leverages the existing user interface, allowing on-site technicians to log into the web portal via mobile devices and submit completion reports directly. For instance, a technician might use a ruggedized tablet to access the web portal, fill out a standardized completion form, and submit it immediately upon finishing the swap.

[0152] Alternatively, the system may be configured for direct communication between field devices and the application server module (216). This configuration is enabled through a combination of hardware and software components. On the hardware side, field devices such as smartphones or specialized handheld units are equipped with cellular or satellite communication capabilities, ensuring connectivity even in remote locations. These devices are preconfigured with the necessary network credentials and security certificates to establish secure connections with the application server.

[0153] On the software side, specialized mobile applications are developed and installed on these field devices. These apps are designed with an API (Application Programming Interface) that is compatible with the application server module (216). The API defines the format and content of messages exchanged between the field device and the server, ensuring standardized communication.

[0154] The system employs machine-to-machine (M2M) communication protocols, such as MQTT (Message Queuing Telemetry Transport) or CoAP (Constrained Application Protocol), which are optimized for low-bandwidth, high- latency networks often encountered in field operations. These protocols enable efficient, real-time data transfer with minimal overhead.

[0155] For example, a custom mobile app installed on technicians' smartphones might be programmed to monitor the progress of swap operations. Aspredefined swap milestones are completed, the app automatically generates structured data packets containing details of the completed tasks, timestamps, and any relevant metrics. These packets are then securely transmitted to the application server module (216) using the predetermined M2M protocol, without requiring manual input from the technician.

[0156] The flexibility in notification routing enhances the system's adaptability to various operational environments. In areas with reliable internet connectivity, web portal submissions might be preferred for their user-friendly interface and integration with other system components. In remote locations with limited connectivity, direct communication to the application server module (216) might be more reliable, possibly utilizing cellular data networks or satellite communications.

[0157] Upon receiving a completion notification, the application server module (216) initiates a series of automated processes. These may include updating the status of the workorder in the system database, triggering notifications to relevant stakeholders, and initiating post-swap verification procedures. For instance, once a completion notification is received for a major urban cell site upgrade, the application server module (216) might automatically alert the network operations center to begin remote testing and optimization procedures.

[0158] The application server module (216) also plays a crucial role in data aggregation and analysis. It collects completion notifications from multiple sites and compiles this information to provide a comprehensive view of the ongoing swap campaign. This aggregated data enables project managers to track overall progress, identify trends in swap durations or common issues, and make data-driven decisions to optimize future swap operations.

[0159] In practice, the application server module (216) might receive a completion notification for a swap operation at a rural tower site. The notification,sent via a specialized mobile app, indicates that a legacy 3G RRH has been replaced with a multi-standard RRH supporting 4G and 5G. Upon receipt, the module updates the site status in the central database, triggers an automated remote connectivity test, and sends an alert to the regional network optimization team to begin fine-tuning the new equipment's parameters.

[0160] By serving as the central point for receiving and processing completion notifications, the application server module (216) ensures that all relevant system components and human operators are promptly informed of the progress of swap operations. This real-time information flow is crucial for maintaining efficient workflows, minimizing downtime, and enabling rapid response to any post-swap issues that may arise. The module's role in this process significantly contributes to the overall effectiveness and reliability of the network equipment swap system.

[0161] Upon receiving the completion notification, the application server module (216) initiates a series of integration tests to verify the implementation of the network equipment swap at the network site. These integration tests are designed to ensure that the newly installed equipment is functioning correctly and is properly integrated with the existing network infrastructure.

[0162] Integration tests represent a comprehensive suite of automated checks and measurements conducted remotely by the application server module (216). These tests aim to validate various aspects of the newly installed equipment's performance and its interaction with other network elements. The scope of these tests typically encompasses connectivity verification, performance benchmarking, and compatibility assessments.

[0163] For example, in the case of a Remote Radio Head (RRH) swap, the integration tests might include verifying the establishment of the CPRI (Common Public Radio Interface) link between the new RRH and the baseband unit. Theapplication server module (216) would send test signals through this link and measure parameters such as latency, bit error rate, and throughput to ensure they meet predefined standards.

[0164] Another aspect of integration testing involves verifying the correct configuration of the new equipment. The application server module (216) may compare the actual configuration parameters of the installed hardware against the intended settings specified in the work order. This might include checking frequency allocations, transmit power levels, and cell identifiers to ensure they align with the network plan.

[0165] The application server module (216) is further configured to evaluate the results of the series of integration tests. This evaluation process involves comparing the test outcomes against predetermined thresholds and expected values. The module employs sophisticated algorithms to analyze the test data and generate a comprehensive assessment of the swap operation's success.

[0166] Based on this evaluation, the module determines whether the network equipment swap was successful or if additional actions are required. Success criteria might include achieving specified performance metrics, maintaining seamless interoperability with adjacent network elements, and ensuring compliance with regulatory requirements such as EMF (Electromagnetic Field) emission limits.

[0167] If the results indicate a successful network equipment swap, the application server module (216) initiates swap activities at the next network site from the list of sites in the workorder. This automated progression helps maintain the momentum of large-scale network upgrade projects. For instance, upon confirming the successful swap of a 4G RRH to a 5G-capable unit at one site, the module might immediately trigger the pre-swap processes for the next site on the list, such as sending notifications to the field team and initiating pre-checks.

[0168] In cases where the integration test results indicate an unsuccessful network equipment swap, the application server module (216) initiates a retry procedure for the network equipment swap at the current network site. An unsuccessful swap might be identified through various indicators, such as failure to establish proper connectivity, performance metrics falling below acceptable thresholds, or detection of configuration mismatches.

[0169] The retry procedure initiated by the application server module (216) involves a structured approach to problem resolution. This may begin with automated troubleshooting steps, where the module attempts to diagnose the issue based on the specific test failures. For example, if the integration tests reveal a configuration mismatch, the module might automatically attempt to push the correct configuration to the new equipment and re-run the affected tests.

[0170] Equipment reconfiguration often forms a key part of the retry procedure. The application server module (216) may execute a series of predefined reconfiguration scripts designed to address common issues. These scripts encompass various crucial adjustments to optimize the newly installed equipment's performance and integration. For instance, one script might focus on fine-tuning the transmit power levels of the new RRH, gradually modifying power output to achieve optimal coverage without causing interference. Another script could address timing synchronization, adjusting timing advance settings to ensure proper alignment with neighboring cells. The module may also employ scripts to reconfigure the Physical Cell Identity if conflicts with adjacent cells are detected post-swap, or to update the automatic neighbour relations, refreshing the neighbour cell list to reflect the new network topology. These scripts might adjust parameters such as timing settings, power levels, or network identifiers in an attempt to resolve integration problems.

[0171] In more complex scenarios, the application server module (216) may determine that another on-site visit is necessary. This decision is typically made when remote troubleshooting and reconfiguration attempts fail to resolve the issues. The module would then generate a new work order, detailing the specific problems encountered and the required on-site actions. For instance, if the integration tests consistently show poor RF (Radio Frequency) performance, the module might schedule a field technician to physically inspect the antenna connections and alignment.

[0172] Throughout the retry procedure, the application server module (216) maintains detailed logs of all actions taken and their outcomes. These logs serve multiple purposes, including providing a trail for auditing purposes, informing future troubleshooting efforts, and contributing to the system's knowledge base for continuous improvement of swap processes.

[0173] By orchestrating this comprehensive sequence of integration testing, result evaluation, and adaptive response, the application server module (216) plays a crucial role in ensuring the success of network equipment swaps. Its ability to rapidly identify and address issues, whether through automated means or by coordinating human intervention, significantly contributes to minimizing network downtime and maintaining service quality during large-scale network upgrade operations.

[0174] The system (102) demonstrates particular efficacy in executing Remote Radio Head (RRH) swaps within telecommunications networks. Remote Radio Heads represent critical components in modem cellular infrastructure, responsible for processing and transmitting radio frequency signals between mobile devices and the core network.

[0175] In the context of RRH swaps, the database (210) serves as a repository for an extensive set of configuration parameters. These parametersencompass crucial details that define the operational characteristics of each network site. The radio node type, for instance, might specify whether the site utilizes equipment from manufacturers such as Ericsson, Nokia, or Huawei, each with its own unique specifications and requirements. Radio node configuration details could include information such as the frequency bands in use, antenna configurations, and power output levels.

[0176] The type of RRH installed at each site represents another vital piece of information stored in the database (210). This might differentiate between singleband and multi-band RRHs, or between units designed for specific network generations such as 4G LTE or 5G NR. For example, a site might currently have a Huawei RRH3971 installed, which is a dual -band unit supporting both 1800 MHz and 2100 MHz frequencies for 4G LTE.

[0177] Firmware versions of installed RRHs constitute a critical aspect of the configuration data. Firmware, being the low-level software that controls the RRH hardware, plays a significant role in determining the unit's capabilities and performance characteristics. The database (210) might store information such as "Version 5.1.2" for a particular RRH, enabling the system to determine compatibility with other network elements and identify any necessary upgrades as part of the swap process.

[0178] The retrieval and utilization of this specialized information empower the system (102) to adeptly manage the intricate requirements associated with RRH swap operations. For instance, when planning a swap from a 4G RRH to a 5G- capable unit, the system can ensure that the new RRH is compatible with the existing antenna system and baseband unit, and that the necessary firmware updates are included in the swap procedure.

[0179] To maintain the integrity of swap operations and mitigate the risk of errors, the one or more processors (202) incorporate a robust validation mechanismfor incoming workorders. This validation process occurs as a preliminary step, preceding the retrieval of configuration parameters from the database (210). The validation encompasses several critical aspects designed to ensure the accuracy and completeness of the workorder data.

[0180] Data completeness checks verify that all required fields in the workorder are populated with appropriate information. This might include ensuring that each site listed in the workorder has a valid site identifier, specific equipment models for both the existing and replacement RRHs, and scheduled dates for the swap operation. For example, a workorder missing the model number of the new RRH to be installed would be flagged as incomplete.

[0181] Format correctness validation ensures that the data within each field adheres to predefined standards. This might involve checking that site identifiers follow a specific alphanumeric pattern, that equipment model numbers match known formats, or that dates are provided in a standardized format. For instance, if site identifiers are expected to follow a pattern like "SITE-XXXX" where X represents digits, a workorder with an entry like "LOCATION- A" would be flagged for format inconsistency.

[0182] Consistency checks compare the workorder data against existing network records to identify any discrepancies. This process might involve crossreferencing the current equipment listed in the workorder with the information stored in the database (210) for each site. If a workorder indicates that a site currently has a Nokia AHQA RRH installed, but the database shows an Ericsson Radio 4415 for that site, the system would flag this inconsistency for review.

[0183] The services module (214) executes a comprehensive set of preswap checks, forming a critical phase in the preparation for physical equipment changes. These checks encompass a thorough verification of the configuration across the plurality of nodes involved in the swap operation. For each network sitelisted in the workorder, the services module (214) examines a diverse set of parameters to ensure readiness for the impending swap.

[0184] Configuration verification might involve remotely querying each node to confirm its current settings align with the records in the database (210). This could include checking the operational frequency bands, verifying the current firmware version of the RRH, and confirming the cell identifiers associated with the site. For example, if a site is scheduled for an upgrade from a single-band to a dual-band RRH, the pre-swap checks would confirm that the existing network configuration can support the additional frequency band.

[0185] Parameter checks conducted by the services module (214) extend beyond just the RRH configuration. They may include assessing power supply capacity to ensure it can support the new equipment, verifying the availability of sufficient physical space in equipment racks for the new RRH, and confirming that the existing antenna system is compatible with the planned new RRH. For instance, if upgrading to a higher-power RRH, the checks would verify that the site's power distribution unit can handle the increased power draw.

[0186] By conducting these comprehensive pre-swap checks, the services module (214) plays a crucial role in identifying potential issues before the physical swap takes place. This proactive approach significantly reduces the likelihood of complications during the actual swap process. For example, if the pre-swap checks reveal that a site's antenna system is incompatible with the planned new RRH, this issue can be addressed before a technician is dispatched, preventing a wasted site visit and potential service disruption.

[0187] The series of integration tests initiated by the application server module (216) are designed to thoroughly assess the success of the network equipment swap. These tests encompass a wide range of checks to ensure optimal functionality and integration of the newly installed equipment. For instance, onekey test involves measuring the Signal-to-Noise Ratio (SNR) at various points in the network. A sudden drop in SNR post-swap could indicate misalignment of the new Remote Radio Head (RRH) or interference issues. Another critical test is the evaluation of data throughput rates. This is typically done by initiating a series of data transfers of varying sizes and measuring the time taken for completion. Any significant deviation from expected transfer rates may signal problems with the new equipment's configuration or its integration with the existing network infrastructure.

[0188] The integration tests also include checks for proper frequency band operation. For example, in a multi-band RRH swap, the system verifies that all configured frequency bands (e.g., 700 MHz, 1800 MHz, 2100 MHz) are operational and providing the expected coverage. This is done through a series of test transmissions on each band, followed by signal strength measurements at predefined test points. Anomalies such as unexpected signal weakness or complete lack of signal on certain bands would be flagged for further investigation.

[0189] Another crucial aspect of the integration tests is the verification of handover functionality. The system simulates user equipment moving between cells and monitors the handover process. Failures or delays in handover could indicate issues with the integration of the new RRH into the broader network ecosystem. Additionally, the system performs load testing by simulating high traffic scenarios. This helps detect any capacity -related issues that may not be apparent under normal operating conditions.

[0190] The integration tests also include protocol- specific checks. For instance, in a 5G network, the system verifies proper implementation of 5G NR protocols by the new equipment. This involves testing features such as beamforming, massive MIMO capabilities, and ultra-low latency performance. Any deviations from expected 5G NR performance metrics are flagged as potential operational anomalies.

[0191] The integration tests executed by the application server module (216) following network equipment swaps are comprehensive and technically rigorous, encompassing multiple dimensions of network performance verification. When detecting operational anomalies, the system employs various measurement techniques specific to radio network performance. For example, the system measures Signal-to-Noise Ratio (SNR) at predetermined test points around the cell site and compares these readings against pre-swap baseline measurements, where a deviation of more than 3dB might indicate an issue with antenna alignment or signal processing. The system also conducts bit error rate testing across all operational frequency bands, such as measuring Packet Error Rate (PER) on both 1800 MHz and 2100 MHz bands for multi -band RRHs, with acceptable thresholds typically set below 1%. Power consumption monitoring represents another critical anomaly detection method, where the system tracks the new equipment's power draw against expected operational thresholds; for instance, a 5G RRH operating at full capacity should maintain power consumption within 15% of manufacturer specifications. The system also evaluates handover performance by simulating user equipment moving between cells at various speeds (3 km / h for pedestrian mobility, 60 km / h for vehicular mobility) and ensuring successful handover rates exceed 98% under normal conditions. For firmware integration verification, the system conducts protocol- specific tests to confirm proper implementation of features enabled by the updated firmware, such as verifying carrier aggregation capabilities or MIMO functionality in 5G equipment. The system also validates CPRI or eCPRI link functionality between the RRH and baseband unit, checking for synchronization accuracy within 50 nanoseconds as required for proper cell operation. Network reconnection verification includes throughput testing under various load conditions, measuring achievable data rates from 10% to 90% of theoretical capacity, assessing Quality of Service (QoS) parameters including latency (targeting <50ms for 4G, <10ms for 5G URLLC applications), and validating the node's integration with the Operations Support System (OSS) by confirming that performance metrics are properly reported to the central monitoring platform.

[0192] To detect more subtle operational anomalies, the system employs advanced analytics during the integration tests. It compares the performance metrics of the newly swapped equipment against historical data from similar deployments. Machine learning algorithms analyze these comparisons to identify patterns that may indicate potential issues, even if individual metrics fall within acceptable ranges. For example, a slight increase in power consumption coupled with a minor decrease in signal strength might not trigger individual alarms, but the combined pattern could signal a developing problem that requires attention. By employing these comprehensive and nuanced testing methodologies, the system can detect a wide range of operational anomalies, from obvious malfunctions to subtle performance degradations, ensuring the newly swapped equipment functions optimally within the existing network infrastructure.

[0193] Detecting operational anomalies forms a cornerstone of the integration testing process. This involves a meticulous examination of various network performance metrics following the equipment swap. The application server module (216) continuously monitors key performance indicators (KPIs) such as signal strength, throughput, latency, and error rates. These metrics are compared against predefined thresholds and historical data to identify any deviations from expected behavior. For instance, if a newly installed Remote Radio Head (RRH) exhibits unexpectedly high error rates or significantly lower signal strength compared to the previous equipment, the system flags these anomalies for further investigation.

[0194] The monitoring process extends beyond basic connectivity checks. It includes assessing the quality-of-service parameters that directly impact user experience. For example, the system might analyze call drop rates, data session establishment success rates, and handover performance between cells. Any unusual patterns or sudden changes in these metrics following the equipment swap trigger alerts within the system, prompting immediate attention from network engineers.

[0195] Another aspect of the integration tests involves verifying the proper integration of the swapped network equipment with the network node, particularly focusing on firmware compatibility. The application server module (216) retrieves the latest firmware version information from the database (210) and compares it with the actual firmware running on the newly installed equipment. This step ensures that the physical installation is complemented by the correct software configuration, which is vital for optimal performance and compatibility with other network elements.

[0196] Firmware verification might involve a series of checks. For instance, the system could send specific commands to the new equipment to query its firmware version and feature set. It then compares this information against the expected configuration as per the swap plan. If discrepancies are found, such as an outdated firmware version or missing features, the system can initiate automated update processes or alert technicians for manual intervention. This thorough approach prevents scenarios where new hardware is installed but fails to provide expected functionality due to software incompatibilities.

[0197] The integration tests also place significant emphasis on verifying the network node's ability to successfully reconnect to the broader network infrastructure and effectively carry network traffic. This aspect of testing is crucial for ensuring that the swapped equipment not only functions in isolation but also integrates seamlessly with the existing network ecosystem. The application server module (216) conducts a series of tests to assess various aspects of network connectivity and performance.

[0198] Data transmission rate testing forms a key component of this verification process. The system generates test data streams and measures the throughput achieved by the new equipment. These tests simulate different types of network traffic, such as voice calls, video streaming, and large file transfers, toensure the equipment can handle diverse traffic patterns. For example, in a 5G equipment swap, the system might verify that the new RRH can achieve the expected multi-gigabit data rates under various network load conditions.

[0199] Signal quality assessment is another element of the integration tests. The application server module (216) analyzes parameters such as Signal-to-Noise Ratio (SNR), Reference Signal Received Power (RSRP), and Error Vector Magnitude (EVM). These metrics provide insights into the clarity and reliability of the radio signal produced by the new equipment. For instance, if a newly installed RRH shows significantly lower RSRP values compared to pre-swap measurements, it might indicate issues with antenna alignment or power settings that require immediate attention.

[0200] The integration tests also evaluate other relevant network performance indicators that reflect the overall health and efficiency of the swapped equipment within the network. These may include assessing the equipment's power efficiency, its ability to handle multiple frequency bands if applicable, and its performance in coordinating with neighboring cells for seamless handovers. For example, in a multi-band RRH swap, the system would verify that all configured frequency bands are operational and providing the expected coverage and capacity.

[0201] By conducting this comprehensive suite of integration tests, the application server module (216) ensures that each network equipment swap not only results in functional hardware installation but also maintains or enhances the overall network performance. This thorough approach significantly reduces the risk of post-swap issues, minimizes service disruptions, and contributes to the continuous improvement of the network infrastructure.

[0202] To ensure optimal performance of the swapped equipment, the one or more processors (202) are configured to perform firmware upgrades for the network equipment as part of the swap process. Firmware, in this context, refers tothe low-level software embedded in network hardware that controls its fundamental operations. These upgrades are automatically initiated based on the information retrieved from the database (210), ensuring that the newly installed equipment is running the most up-to-date and compatible firmware version.

[0203] The firmware upgrade process typically involves several stages. Initially, the processors (202) query the database (210) to determine the latest approved firmware version for the specific equipment model being installed. For example, if a new Ericsson AIR 3246 Remote Radio Unit is being deployed, the system might identify that firmware version 22. Q2 is the most recent validated release. The processors then compare this version with the currently installed firmware on the new equipment. If a discrepancy is detected, the upgrade process is initiated.

[0204] During the upgrade, the processors (202) manage the transfer of the firmware files to the network equipment, often utilizing secure file transfer protocols to ensure data integrity. The installation process is closely monitored, with the processors verifying checksums and performing post-installation tests to confirm the upgrade's success. This automated approach minimizes the risk of human error and ensures consistency across multiple equipment swaps.

[0205] In addition to firmware upgrades, the one or more processors (202) perform a set of configurations for the network equipment. These configurations encompass a wide range of settings crucial for the equipment's optimal operation within the network ecosystem. Operational parameters might include frequency band allocations, transmission power settings, and cell identifiers. For instance, in a multi-band base station, the processors might configure each radio unit to operate on specific frequency bands (e.g., 700 MHz, 1800 MHz, 2600 MHz) based on the network design and licensing agreements.

[0206] Power level adjustments form another critical aspect of the configuration process. The processors (202) set appropriate transmit power levels for each sector and frequency band, taking into account factors such as coverage requirements, interference management, and regulatory limits. For example, in an urban area with high user density, the system might configure higher power settings to support increased capacity demands, while in rural areas, it might optimize for extended coverage.

[0207] Network interface configuration involves setting up the connectivity between the new equipment and other network elements. This might include configuring IP addresses, VLAN settings, and interface speeds. For a newly installed Remote Radio Head, the processors (202) would ensure proper configuration of the CPRI (Common Public Radio Interface) or eCPRI (enhanced CPRI) link connecting it to the baseband unit, including parameters such as link speed and synchronization settings.

[0208] The one or more processors (202) are also capable of performing network optimizations following the equipment swap. These optimizations are designed to leverage the capabilities of the new equipment fully and ensure it integrates seamlessly with the existing network infrastructure. Network routing adjustments might involve updating routing tables to accommodate changes in network topology resulting from the equipment swap. For instance, if a new high- capacity link is introduced, the processors might reconfigure traffic routes to utilize this enhanced capacity effectively.

[0209] Load balancing optimizations focus on distributing network traffic efficiently across available resources. After a swap that introduces enhanced capacity, the processors (202) might adjust load sharing algorithms to direct more traffic through the upgraded equipment. This could involve modifying user association parameters or adjusting handover thresholds between cells to optimize resource utilization.

[0210] After successful completion of the network equipment swap and all associated tests and configurations, the one or more processors (202) integrate the network site back into the network to carry production traffic. This final step is crucial in transitioning the newly swapped equipment from a testing phase to full operational status. The integration process involves a series of coordinated actions to ensure a smooth transition.

[0211] The processors (202) might begin by gradually increasing the traffic load on the new equipment, monitoring key performance indicators throughout the process. For example, in a cellular network, this could involve slowly expanding the coverage area of the new equipment by adjusting its neighbor relations and handover parameters. The system continuously monitors metrics such as call success rates, data throughput, and latency to ensure the integration progresses without degrading user experience.

[0212] One of the key features of the system (102) is its ability to perform network equipment swaps across multiple types of radio nodes with different software versions in the network. This flexibility is crucial in modem telecommunications networks, which often comprise equipment from various vendors and multiple technology generations. The system's adaptability allows it to manage swaps in diverse scenarios, from upgrading legacy 3G equipment to the latest 5G technology or replacing equipment from one vendor with another's.

[0213] For instance, the system (102) might be tasked with swapping out Nokia base station equipment running software version 18.Q4 with Ericsson equipment running version 22.Q1. The processors (202) would access vendorspecific configuration templates and conversion tools stored in the database (210) to ensure proper translation of parameters between the different ecosystems. This capability significantly reduces the complexity and potential for errors in heterogeneous network environments.

[0214] The user interface module (212) of the system (102) is further configured to receive notifications from the on-site team indicating completion of the network equipment swap. These notifications serve as a critical communication link between field operations and the backend systems. When a field technician completes the physical installation of new equipment, they can use the web portal to submit a detailed completion report. This report might include information such as the exact time of completion, any deviations from the planned procedure, and initial on-site observations about the equipment's functionality.

[0215] The real-time nature of these notifications enables efficient coordination between field teams and backend systems. For example, as soon as a completion notification is received for a particular site, the processors (202) can immediately initiate the post-swap testing and optimization procedures. This tight integration between on-site activities and automated backend processes minimizes downtime and accelerates the overall swap process, particularly in large-scale network upgrade projects involving multiple sites.

[0216] By automating and streamlining the process of network equipment swaps, this system (102) reduces the time, and resources required for such operations. The combination of pre-swap checks, automated configurations, and thorough post-swap testing contributes to increased reliability and reduced downtime during equipment upgrades or replacements.

[0217] The system's (102) ability to manage complex swap operations across multiple sites provides network operators with a powerful tool for maintaining and upgrading their infrastructure efficiently. By coordinating between automated processes and on-site teams, the system (102) helps optimize resource allocation and improve the overall effectiveness of network maintenance activities.

[0218] In another embodiment, the present disclosure may relate to a non- transitory computer-readable medium. The non-transitory computer-readable medium may store instructions for performing network equipment swaps across nodes. The instructions, when executed by processors (202) of a system (102), may cause operations. These operations may include receiving a workorder via a user interface module (212). The workorder may list network sites for equipment swaps. The operations may involve retrieving configuration parameters for each site from a database (210). They may include executing pre-swap checks through a services module (214). The system may receive a completion notification via an application server module (216). This may indicate the swap performance by an on-site team. The operations may conclude with initiating integration tests through the application server module (216). These tests may verify the swap implementation at the network site.

[0219] FIG. 3 illustrates an exemplary system architecture (300) for performing remote radio head (RRH) swaps across multiple nodes in a network (104), in accordance with an embodiment of the present disclosure.

[0220] The system architecture (300) comprises a plurality of user equipments - web portals (108), a load balancer (302), web servers (304), application servers (306), gateway servers (308), reporting servers (310), a distributed file system (DFS) (312), services (314), a database management system (316) and a database (210).

[0221] The user devices - web portals (108) (e.g., backend user’s system) may create a workorder. The workorder comprises action items on multiple sites on which activity is to be planned. The user equipment (108) may send the created workorder to the load balancer (302). The load balancer (302) may communicate the workorder to one or more web servers based on the load of the web servers (304). The web server(s) (304) may send the workorder request to their corresponding the application server (306) and the gateway server (308). Theapplication server (306) may process the workorder by retrieving the data corresponding to the workorder from the database (210) via the reporting server (310) and the DFS (312). Similarly, the gateway server (308) may send the workorder to the services (314). The services (314) may process the workorder by retrieving the data from the database management system (210) and the DFS (312). The retrieved data comprises radio node type, node configuration, type of RRH unit installed, firmware version, etc.

[0222] The load balancer (302) serves as the entry point of the system architecture (300). It distributes incoming requests from user equipments (108-1, 108-2...108-N) across an array of web servers (304). For example, when a network engineer submits a workorder for an RRH swap via their laptop (user equipment 108-1), the load balancer (302) directs this request to the web server with the lowest current load.

[0223] The web servers (304) host the user interface module (212), providing the user interface for workorder creation, submission, and management. The user interface module (212) communicates directly with the web servers (304), enabling users to interact with the system. A project manager uses the user interface module (212) to create a workorder for swapping 20 RRHs from 4G to 5G capability across a metropolitan area.

[0224] The application servers (306) connect directly to the web servers (304) and host the application server module (216). This module forms the core logic unit of the RRH swap system, processing workorders, initiating pre-swap checks, managing integration tests, and coordinating the overall swap process. The application server module (216) communicates with the web servers (304) to receive workorder information and with the Database Management System (DBMS) (316) to retrieve and store data.

[0225] The gateway server (308) interfaces between the internal system components and external networks or systems. It connects to the application servers (306) and manages secure communications and data transfers. The gateway server (308) communicates with vendor systems, weather services, and other network management systems as required for the swap process.

[0226] Reporting servers (310) generate and manage reports and analytics related to RRH swap operations. These servers receive data from the application servers (306) and the services module (214), providing insights into swap performance, success rates, and efficiency metrics.

[0227] The services module (214) resides within the services component (312) and performs critical tasks such as pre-swap checks, configuration management, and post-swap optimizations. The pre-swap checks are performed through a series of automated processes including network connectivity verification using Internet Control Message Protocol (ICMP) and Simple Network Management Protocol (SNMP), equipment compatibility analysis through vendor- specific APIs, and resource availability confirmation via inventory management system integration. Configuration management is executed through template -based parameter generation, where the system dynamically creates configuration files based on network topology information, equipment specifications, and site-specific requirements. These configurations are then deployed using secure file transfer protocols and vendor- specific command interfaces. Post-swap optimizations are implemented through a series of automated adjustments to network parameters based on real-time performance metrics. These adjustments include fine-tuning of transmit power levels using iterative measurements and calibration, optimization of handover parameters through analysis of cell transition statistics, and reconfiguration of frequency allocations based on interference measurements and traffic patterns. The services module communicates directly with the application servers (306) and the Database Management System (DBMS) (316) to retrieve and update configuration data.

[0228] The Distributed File System (DFS) (312) connects to the application servers (306), services (314), and reporting servers (310). It stores large volumes of data generated during swap operations, including detailed logs, configuration files, and historical performance data.

[0229] The Database Management System (DBMS) (316) manages the database (210) and communicates directly with the application servers (306) and services (314). It organizes, stores, and retrieves critical data used throughout the swap process, including network site information, equipment specifications, and operational parameters.

[0230] In the system's workflow, the load balancer (302) routes incoming requests to a web server (304). The web server (304) forwards the workorder to an application server (306). The application server module (216) processes the workorder, retrieving necessary data from the database (210) via the DBMS (316). Simultaneously, the services module (214) initiates pre-swap checks, communicating with the application server module (216) and the DBMS (316). The gateway server (308) manages external communications as required. Throughout the process, the reporting servers (310) collect data from the application servers (306) and services (314) for analysis and reporting.

[0231] This interconnected architecture enables efficient management of complex RRH swap operations, coordinating automated processes and human interventions to ensure successful equipment upgrades with minimal network disruption.

[0232] FIG. 4 illustrates an example of a flow diagram (400) for performing swapping of the remote radio head (RRH) in the network, as implemented by the system (102) and corresponding to the method, in accordance with an embodiment of the present disclosure. The flow diagram (400) depicts the sequential operationsperformed by various components of the system (102), including the user interface module (212), the services module (214), and the application server module (216), working in coordination to execute the RRH swap process across multiple network sites.

[0233] Step 402 involves obtaining RRH work order (WO) details from the user equipment (108-1, 108-2...108-N) via the user interface module (212). The work order, created by the backend team, comprises a comprehensive plan for multiple sites where RRH swaps are scheduled. For instance, a network operations manager might create a work order detailing 15 sites across a metropolitan area where 4G RRHs need upgrading to 5G-capable units.

[0234] Step 404 entails receiving a bulk upload of data in various structured formats. This data may be provided in multiple industry-standard formats, including Comma-Separated Values (CSV) files, JavaScript Object Notation (JSON) documents, Extensible Markup Language (XML) files, Excel spreadsheets (XLSX), or proprietary telecommunications equipment configuration formats. For example, a network operator might upload a CSV file containing site IDs and equipment details, a JSON document with network topology information, or an XML file exported from their inventory management system. The system is designed to process and interpret these various data formats, extracting the necessary information for the swap operations regardless of the input format. This file contains detailed information about each swap operation, including site locations, equipment specifications, and scheduled dates. For example, a CSV file might list site IDs, current RRH models, target RRH models, and planned swap dates for a large-scale network upgrade project.

[0235] In step 406, the services module (214) validates the RRH WO / CSV input data. This crucial step ensures the integrity and completeness of the provided information. The validation process checks for correct data formats, consistency with existing network records, and completeness of required fields.

[0236] Step 408 is triggered when the RRH WO / CSV input data is deemed valid. The system creates a new entry in the database (210) and ingests the work order details. This step involves parsing the input data and storing it in both structured and unstructured formats for efficient retrieval and processing during subsequent stages of the swap operation. The system is capable of handling structured data with predefined schemas, such as relational database tables with well-defined fields for site information, equipment specifications, and scheduling details. Simultaneously, it can process and store unstructured data components, including free-text maintenance notes, equipment images, RF coverage maps, and site-specific documentation, using flexible storage mechanisms like document databases and distributed file systems. This dual-format approach enables the system to maintain rigid data relationships for critical operational parameters while preserving contextual information that doesn't conform to fixed schemas, ensuring comprehensive data availability throughout the swap process.

[0237] Conversely, step 410 is activated if the RRH WO / CSV input data is found to be invalid. In this case, the system invalidates the RRH WO input request, preventing further processing of the flawed data. The system may generate an error report detailing the reasons for invalidation, such as missing critical information or data format inconsistencies.

[0238] Step 412 involves the automatic execution of backup and precheck tasks by the services module (214). This step ensures that all necessary preparations are made before the physical swap occurs. Backups might include saving current network configurations, while prechecks could involve verifying site accessibility, confirming equipment availability, and checking for any scheduled maintenance that might interfere with the swap.

[0239] In step 414, the system detects the completion of the prechecking phase. This confirmation signals that all preparatory tasks have been successfully completed and the system is ready to proceed with the physical swap process.

[0240] Step 416 marks the beginning of the on-site activities. The on-site team arrives at the designated site to perform the RRH swap. This on-site team, consisting of qualified field technicians with expertise in telecommunications equipment, is responsible for executing the physical aspects of the equipment replacement process. They communicate with the backend team to initiate the site shutdown procedure, often referred to as "stopping site radiation." The system enables an execute button, signaling the start of the swap execution. The backend team uses the system to power down the site safely. Once the site is inactive, the on-site team performs the physical swap of the RRH unit and notifies the backend team upon completion. They communicate with the backend team to initiate the site shutdown procedure, often referred to as "stopping site radiation." The system enables an execute button, signaling the start of the swap execution. The backend team uses the system to power down the site safely. Once the site is inactive, the on-site team performs the physical swap of the RRH unit and notifies the backend team upon completion.

[0241] In step 418, the system performs RRH swap validation. This process involves collecting and analyzing logs related to the RRH swap. These logs might include power-up sequences, initial configuration settings, and connectivity test results.

[0242] Step 420 involves checking whether the execution of the RRH swap has passed or failed based on the validation results from the previous step. The system analyzes operational metrics against predefined thresholds to determine swap success or failure.

[0243] If the swap execution is deemed successful, step 422 is triggered, where the system disables the action / retry button. This action prevents unnecessary repeat attempts for a successfully completed swap.

[0244] However, if the swap execution is found to have failed, step 424 is activated. The system re-enables the execution button, allowing for a retry of the swap process. The flow then returns to step 416, and the process is repeated. The backend team conducts comprehensive integration tests and, based on the results, instructs the on-site team to either reattempt the swap or proceed to the next site in the work order.

[0245] Throughout this process, the system performs multiple activities crucial for successful network integration. These include firmware upgrades to ensure the new RRH is running the latest software version, unit configurations to align the new equipment with network parameters, and various optimizations to enhance performance. Finally, the system reintegrates the upgraded site into the network, enabling it to carry production traffic.

[0246] This systematic approach ensures efficient and reliable RRH swaps across multiple sites, minimizing network downtime and optimizing the upgrade process.

[0247] FIG. 5 illustrates an exemplary flow diagram of a method (500) for performing network equipment swaps across a plurality of nodes in a network, as implemented by the system (102) and its components including the user interface module (212), the database (210), the services module (214), and the application server module (216), in accordance with embodiments of the present disclosure. The method (500) depicts the logical flow of operations executed by these interconnected components to systematically manage the equipment swap process from initial workorder creation through final integration testing and network optimization.

[0248] At step (502), the method (500) includes receiving, via a user interface module (212), a workorder comprising a list of network sites where network equipment swaps are to be performed. This step involves the creation and submission of a comprehensive workorder through a user-friendly web interface. For example, a network operations manager might create a workorder detailing 20 sites across a metropolitan area where Remote Radio Heads (RRHs) need to be upgraded from 4G to 5G capability. The workorder typically includes site locations, equipment specifications, and scheduled swap dates.

[0249] At step (504), the method (500) includes retrieving, from a database (210), a set of configuration parameters corresponding to each network site of the list of network sites. This step involves accessing the centralized database to gather critical information about each site listed in the workorder. The configuration parameters may include radio node type, radio node configuration, type of RRH installed, and firmware version of the installed RRH. For instance, for a particular site, the system might retrieve data indicating an Ericsson RBS 6000 base station with a 4G LTE RRH operating on the 1800 MHz band, running firmware version 22.Q1.

[0250] At step (506), the method (500) includes executing, through a services module (214), a set of pre-swap checks on each network site of the list of network sites. These pre-swap checks are crucial for ensuring the swap's success and minimizing potential issues. The checks may include verifying the configuration of the plurality of nodes and a set of parameters for each network site. For example, the system might verify network connectivity to the site, confirm the availability of necessary replacement parts, and validate that the new RRH's specifications are compatible with the existing network infrastructure.

[0251] At step (510), the method (500) includes receiving, via an application server module (216), a completion notification indicating that thenetwork equipment swap has been performed by an on-site team deployed to perform physical equipment changes at a network site from the list of network sites. This step involves the on-site team submitting a notification through the system once they have completed the physical swap of equipment. The notification might include details such as the time of completion, any challenges encountered, and initial observations about the new equipment's functionality.

[0252] At step (512), the method (500) includes initiating, through the application server module (216), a series of integration tests to verify implementation of the network equipment swap at the network site. These tests are designed to ensure that the newly installed equipment is functioning correctly and properly integrated with the existing network infrastructure. The integration tests may include detecting operational anomalies in the network site following the swap, determining whether the swapped equipment is integrated with the network node using updated firmware, and verifying whether the node is successfully reconnected to the network and capable of carrying traffic.

[0253] The method (500) further includes evaluating, through the application server module (216), results of the series of integration tests. Based on these results, the system determines the next course of action. If the results indicate a successful network equipment swap, the application server module (216) initiates swap activities at the next network site from the list of network sites. This ensures a smooth progression of the upgrade process across multiple sites. If the results indicate an unsuccessful network equipment swap, the application server module (216) initiates a retry procedure for the network equipment swap at the current network site. This might involve troubleshooting steps, equipment reconfiguration, or scheduling another on-site visit if necessary.

[0254] In cases where the network equipment swap is specifically a remote radio head (RRH) swap, the set of configuration parameters retrieved from the database (210) comprises detailed information about the radio infrastructure. Thisincludes the radio node type (e.g., macro cell, small cell), radio node configuration (e.g., sector configuration, frequency bands), type of RRH installed (e.g., singleband, multi-band), and firmware version of the installed RRH. This comprehensive set of parameters ensures that the swap process is tailored to the specific requirements of each site.

[0255] The method (500) also includes a validation step for the received workorder prior to retrieving the set of configuration parameters from the database (210). This validation process helps to ensure the integrity and completeness of the workorder, preventing potential issues that could arise from incorrect or incomplete information. For example, the system might check that all required fields are filled, site identifiers are valid, and the specified equipment types are compatible with the planned upgrades.

[0256] The set of pre-swap checks executed by the services module (214) is comprehensive and includes verifying the configuration of the plurality of nodes and a set of parameters for each network site of the list of network sites. These checks help identify potential issues before the physical swap takes place, reducing the likelihood of complications during the actual swap process. For instance, the system might verify power requirements, physical space constraints, and network connectivity for each site.

[0257] The series of integration tests initiated by the application server module (216) are designed to thoroughly assess the success of the network equipment swap. These tests include detecting operational anomalies in the network site following the network equipment swap, which involves monitoring network performance metrics and identifying any deviations from expected behavior. The tests also determine whether the swapped network equipment is integrated with the network node using the updated firmware retrieved from the database (210), ensuring that the new equipment is not only physically installed but also properly configured and running the correct software version. Additionally, the tests verifywhether the network node with the swapped network equipment is successfully reconnected to the network and capable of carrying network traffic, involving checks on data transmission rates, signal quality, and other relevant network performance indicators.

[0258] The method (500) further includes performing firmware upgrades for the network equipment as part of the swap process. This ensures that the newly installed equipment is running the most up-to-date and compatible firmware version, maximizing its performance and functionality within the network.

[0259] In addition to firmware upgrades, the method includes performing a set of configurations for the network equipment. These configurations encompass setting operational parameters, adjusting power levels, configuring network interfaces, and other equipment- specific settings necessary for optimal performance within the network.

[0260] The method (500) also involves performing network optimizations following the equipment swap. These optimizations may include adjusting network routing, load balancing, or other parameters to ensure that the network as a whole benefits from the newly installed equipment. For example, the system might reconfigure neighboring cells to optimize handover performance with the newly upgraded site.

[0261] After successful completion of the network equipment swap and all associated tests and configurations, the method includes integrating the network site back into the network to carry production traffic. This final step ensures that the swapped equipment is fully operational and contributing to the network's overall performance and capacity.

[0262] The method (500) is designed to perform network equipment swaps across multiple types of radio nodes with different software versions in the network.This flexibility allows the system to be used in diverse network environments and accommodate various equipment types and configurations, making it suitable for complex, heterogeneous network infrastructures.

[0263] Lastly, the method includes receiving, via the user interface module (212), a notification from the on-site team indicating completion of the network equipment swap. This real-time communication enables efficient coordination between field teams and backend systems, allowing for prompt initiation of postswap procedures and minimizing overall downtime.

[0264] In another exemplary embodiment, a user equipment (108) communicatively coupled to the system (102) for performing network equipment swaps across a plurality of nodes via a network (104) is described. The user equipment (108) comprises a memory (204) and one or more processors (202) configured to perform operations corresponding to the method (500) as described above. This user equipment could be a laptop, tablet, or smartphone used by field technicians or network engineers to interact with the central system, submit workorders, receive instructions, and provide completion notifications for equipment swaps.

This advancement addresses the limitations of existing solutions by automating and streamlining the process of network equipment swaps, particularly for Remote Radio Head (RRH) upgrades. The disclosure involves a comprehensive system and method for managing complex swap operations across multiple sites, which offer significant improvements in efficiency, reliability, and scalability of network upgrades.
