All rights to such intellectual property are fully reserved by the owner.

TECHNICAL FIELD

[0002] The present disclosure relates to the field of telecommunications and network management. More precisely, it relates to a system for the identification of high-ranking neighbor cells for handing over the user’s connection from the present serving cell to the neighbor cell.

DEFINITION

[0003] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used to indicate otherwise.

[0004] The expression ‘handover” used hereinafter in the specification refers to a process of transferring an ongoing communication session (such as a call or data session) from one base station (eNodeB) to another as a user moves between coverage areas. This process is crucial for maintaining seamless connectivity and ensuring quality of service as users move within the network.

[0005] The expression ‘handover share’ used hereinafter in the specification refers to an allocation or distribution of resources, such as spectrum or bandwidth, among different network nodes (base stations or gNBs - gNodeBs). This allocation determines how much capacity each node has for handling handover procedures and ensuring smooth transitions for users moving between cells.

[0006] These definitions are in addition to those expressed in the art.

BACKGROUND

[0007] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0008] Whenever a mobile device moves from one cell to another, the network needs to identify the most suitable neighboring cell for handover to maintain a stable connection and deliver a high-quality user experience. Cellular networks are composed of a grid of cells, each served by a base station or cell tower. These cells collectively provide coverage to a specific geographical area. When a mobile device moves from one cell to another, it needs to connect to a neighboring cell with a stronger signal and better service quality. Handover is the process of transferring an ongoing call or data session from one cell to another. It is initiated when the signal strength of the serving cell weakens below a certain threshold or when a neighboring cell provides a stronger signal. Handover aims to ensure uninterrupted service and minimize call drops or data interruptions during the transition.

[0009] To identify high-ranking neighbor cells, the network collects measurements from both the serving cell and neighboring cells. These measurements include signal strength, signal quality, interference levels, cell load, available capacity, and other performance metrics. These measurements help assess the quality and suitability of neighboring cells for handover. Various algorithms and techniques are used to evaluate the collected measurements and determine the ranking or priority of neighboring cells. These algorithms may consider factors such as signal strength, signal-to-interference ratio (SIR), quality of service requirements, cell load balancing, and network policies. Machine learning techniques can also be employed to improve the accuracy of handover decisions. The identification of high-ranking neighbor cells plays a crucial role in network optimization. By selecting the most suitable neighboring cells for handover, the network can improve signal coverage, minimize call drops, balance network traffic, and enhance overall network performance and capacity.

[0010] The identification of high-ranking neighbor cells involves understanding the principles of handover, the collection of network measurements, the utilization of decision algorithms, and the overall goal of network optimization. By effectively identifying and selecting high ranking neighbor cells, telecommunications systems can ensure seamless handovers, provide better coverage and service quality to mobile devices, and deliver an enhanced user experience.

[0011] Existing systems for the identification of high-ranking neighbor cells in telecommunications networks vary depending on the specific technology and network infrastructure. The Received Signal Strength (RSS) Based Systems determine the quality of neighboring cells based on their received signal strength. The system selects the neighbor cell with the strongest signal as the high-ranking neighbor cell. However, this approach has drawbacks as it may not consider other important factors such as interference, signal quality, or network load, which can impact the overall performance and suitability of the neighbor cell. The Signal-to- Interference Ratio (SIR) Based Systems evaluate the SIR of neighboring cells to identify high ranking neighbor cells. Higher SIR indicates better signal quality and lower interference. However, SIR-based systems may not account for other crucial factors such as cell load, traffic conditions, or specific quality of service requirements, which can affect the selection of an optimal neighbor cell.

[0012] There is, therefore, a need to overcome the above drawbacks and limitations in the current practices to provide an optimal solution for identifying neighbor cells with a high rank to transfer the user’s connection. The system in the present disclosure aims to leverage a combination of parameters, employ intelligent algorithms, and consider real-time network conditions to accurately identify high ranking neighbor cells for optimal handover decisions.

[0054] The various embodiments throughout the disclosure will be explained in more detail with reference to FIGS. 1-5.

[0055] The present disclosure relates to the field of telecommunications and network management. More precisely, it relates to a system for the identification of high-ranking neighbor cells for handing over the user’s connection from the present serving cell to the neighbor cell.

[0056] FIG. 1A illustrates a network architecture (100- 1) of a system for identifying one or more high rank neighbor cells in a network, in accordance with an embodiment of the present invention.

[0057] The network architecture (100-1) comprises a controller (104), a plurality of base stations (106-1, 106-2, 106-3, 106-4... 106-N) and at least one user equipment (108) in a network (102). The controller (104) may be a system for identification of high ranked neighbor cells in the network (102). The plurality of base station may be communicatively coupled to the user equipment (108). The plurality of base station is communicatively coupled to the controller (104).

[0058] FIG. IB illustrates a block diagram for identification of high ranked neighbor cells, in accordance with an embodiment of the present disclosure.

[0059] As illustrated, in FIG. IB, a block diagram of the system (100-2) for identification of high ranked neighbors is disclosed.

[0060] At step (120), the system (100-2) in the present disclosure collects neighbor related statistics from vendor element management system (EMS). The neighbor related statistics may include raw performance management counter data. The neighbor related statistics comprises a signal strength, a signal quality, a plurality of interference levels, a data throughput, call drop rates, a latency, and a capacity.

[0061] At step (130), the system (100-2) in the present disclosure finds the list of potential neighbor for all the cells on rolling weekly basis. The total handover attempts towards all the interfaces over a rolling period of 7 days is counted for all the cells in the service area. Similarly, total handover attempts towards all the interfaces over a rolling period of 7 days is counted for each of the unique sourcetarget pair. The percentage of contribution of attempts of each source-target pair in overall Handover attempts is also computed.

[0062] At step (140), the handover share is computed as total HO attempts per source-target pair to total HO attempts for each cell. The percentage of contribution/share of attempts of each source-target pair in overall Handover attempts is also computed.

[0063] At step (150), the source-target pairs are arranged in descending order basis of a percentage share of handover attempts. Any source-target pair having more than 10% (value is configurable) of a handover share is identified as a high ranked neighbor. The system (100-2) computes key performance indictors (KPIs) for source-target pair and assigns rank. The KPIs comprises signal strength, signal quality, a plurality of interference levels, load balancing requirements, a coverage area, a capacity, and a plurality of operator-defined policies.

[0064] At step (160), the high ranked neighbors are identified with these features which are used in other algorithms like capacity planning and also for cell compensation for mitigating the cell outage. The high ranked neighbor cells state helps the operations team to identify the cause for the performance degradation of the other cells.

[0065] In an embodiment, in a typical telecom network, as represented in the system (100-2) in the present disclosure, maintaining service continuity and good customer experience is of prime importance. Providing good customer experience in case of mobility scenario is a challenging task as the end user is not static. In such a scenario, the user can be latched initially to one of the telecom nodes and during the ongoing call/data session it might happen that the user’s connection is handed over from the present serving cell to the neighbor cell. To ensure a seamless experience it becomes essential to have proper handover related definitions between the adjacent nodes and all the neighbor definitions which are properly audited and optimized parameter settings are in place. With the introduction of self-optimization feature in next generation networks (5G/6G), the system (100-2) adds the neighbors automatically based on certain pre-defined criteria. Generally, one cell can have to the tune of number of neighbor cells and the number of neighbor cells may vary from case to case depending upon the Handover scenario. In such a case, it is essential to identify the high ranked neighbor which are required for capacity planning of the network. In the case of cell outage to improve the customer experience, cell compensation is done by optimizing the high ranked neighbors. Moreover, in most of the cases each of the source cell will be having very few potential neighbors which will be contributing to 90-95 percentage of overall handover attempts.

[0066] In an embodiment, the optimal strategy for identifying high ranked neighbor cells in a telecommunications network may vary depending on networkspecific requirements and conditions. The system (100-2) chooses relevant performance metrics that accurately reflect the quality and suitability of neighbor cells. These metrics can include signal strength, signal quality, interference levels, data throughput, call drop rates, latency, and capacity. The system (100) assigns appropriate weights to performance metrics based on their significance in determining the ranking of neighbor cells. It also sets threshold values for each metric to define the desired performance level for high ranked neighbors and finetunes the weights and thresholds based on network-specific requirements and quality of service (QoS) targets. The system (100-2) can include weighted averaging, fuzzy logic, machine learning, or other statistical methods. Consider algorithms that can effectively handle large datasets, adapt to changing network conditions, and provide accurate rankings based on the chosen metrics. The system (100-2) is designed to adapt dynamically to real-time network changes and continuously monitor and update the performance metrics and rankings based on the latest data. [0067] FIG. 2 illustrates an exemplary block diagram of the system (100-2), in accordance with an embodiment of the present disclosure.

[0068] As illustrated, in FIG. 2, an exemplary block diagram (200) of the processing engine (208) and all its modules is disclosed. The processing engine (208) for high ranked neighbor identification in telecommunications network typically involves the use of advanced algorithms and computational techniques. The processor (202), memory (204), and interface (206) are used for execution of programming instructions. The processing engine (208) analyses collected data, applies algorithms, and performs calculations to determine the ranking of neighbor cells and the database (218) stores all data. The processing engine (208) collects relevant network measurements and parameters from the serving cell and neighboring cells. This data includes signal strength, signal quality, interference levels, cell load, available capacity, and other performance metrics. The collected data is pre-processed to ensure consistency, accuracy, and compatibility for further analysis. The designated modules and the other executing modules (216) are used for an execution of identification of high ranked cells.

[0069] The performance module is configured to compute one or more key performance indicators (KPIs) for the plurality of neighbor cells based on the data aggregated corresponding to each of the plurality of parameters over a first predetermined time period. In an example, the plurality of parameters comprises one or more of a signal strength, a signal quality, a plurality of interference levels, a data throughput, call drop rates, a latency, and a capacity of the neighboring cells. In an example, the first predefined time lies in a range of 15 to 30 minutes. The performance module is configured to compute a plurality of KPIs for a plurality of source-target pairs. Each source-target pair comprises a source cell and a target cell for handover. The performance module is configured to compute a total handover (HO) attempts towards over one or more interfaces for a second predefined period for each source-target pair in the service area. The interface is a connection point between the source cell and the target cell. In an example, the second predefined time lies in a range of one hour to two hours. The performance module is configured to calculate a percentage of HO share contributed by each source-target pair, wherein the percentage of HO share contributed by each source-target pair is based upon a number of HO attempts per source-target pair. The percentage of HO share is defined as { 100 * [(total number of HO attempts per source-target pair) / (total number of HO attempts for all interfaces for the source cell)] } .

[0070] In an embodiment, a performance module (210) is used for the identification of high ranked neighbor cells in a telecommunications network and is responsible for evaluating the performance metrics and determining the suitability of neighboring cells for handover. It involves analysing various performance indicators and applying algorithms to assess the quality and ranking of neighbor cells. The performance module (210) collects and analyses performance metrics related to neighboring cells, such as signal strength, signal quality, interference levels, data throughput, call drop rates, latency, and other relevant parameters. These metrics are used to evaluate the performance of neighbor cells and determine their ranking. The performance module (210) sets threshold values for performance metrics based on network operator policies, quality of service (QoS) requirements, and industry standards. These thresholds define the acceptable levels of performance for high ranked neighbor cells. Metrics that fall within or exceed the defined thresholds are considered favourable for handover. The performance module (210) evaluates the collected metrics against the predefined thresholds and algorithmic rules. It assesses the performance of each neighbor cell and assigns scores or rankings based on their compliance with the performance criteria. The neighbor cells that exhibit superior performance characteristics are assigned high rankings.

[0071] In an embodiment, an aggregation module (212) can be used to consolidate and analyse data from multiple sources to determine the overall ranking. The aggregation module is configured to collect data corresponding to a plurality of parameters related to a plurality of neighboring cells from an element management system (EMS). The aggregation module (212) collects relevant data from various sources, such as network measurement databases, performance monitoring systems, network management systems, and other data repositories. This data includes performance metrics, signal strength, signal quality, interference levels, load information, and other parameters related to neighbor cells. It also integrates the collected data from different sources and consolidates it into a unified dataset. This integration process ensures that all relevant data points are considered in the analysis. The aggregation module (212) may also perform data cleansing and normalization to ensure consistency and accuracy. The aggregation module (212) assigns weights to different performance metrics or parameters based on their significance in determining the ranking of neighbor cells. For example, signal quality may be given higher weightage compared to signal strength or interference levels. The aggregation module (212) applies an aggregation algorithm to combine the weighted performance metrics and parameters for each neighbor cell. This algorithm calculates an aggregated score or rank based on the weighted values. Various aggregation techniques can be used, such as weighted averages, weighted sums, or more advanced methods like multi-criteria decision-making algorithms. [0072] In an embodiment, the aggregation module (212) also calculates the rankings of neighbor cells. Cells with higher aggregated scores are assigned higher rankings, indicating their suitability as high ranked neighbors. The ranking calculation process may involve normalization of scores to ensure fair comparison across different metrics. The aggregation module (212) is designed to adapt to dynamic network conditions and changing data. It continuously updates the aggregated scores and rankings based on real-time data updates. This ensures that the rankings remain up to date and reflective of the current network performance. The aggregation module (212) integrates with the handover decision process, providing the ranking information to the handover control system (100-2) or network management systems. This enables the selection of high ranked neighbor cells for handover decisions, considering the aggregated scores and rankings. The aggregation module (212) plays a critical role in consolidating and analysing data from multiple sources to determine the overall ranking of neighbor cells. By considering various performance metrics and applying appropriate aggregation techniques, it provides a comprehensive evaluation of neighbor cell suitability for handover, enabling the selection of higher ranked neighbors for improved network performance and user experience.

[0073] In an embodiment, a source-target module (214) is used for determining the potential neighbor cell candidates that have a high ranking compared to the serving cell. The source-target module is configured to identify one or more source- target pairs having the percentage of HO share greater than a defined threshold. The source-target module is configured to identify the one or more high rank neighbor cells by ranking the identified source-target pairs having the percentage of HO share greater than the defined threshold and generate a list of the high ranked neighbor cells associated with each source cell. It analyses the relationship between the serving cell and potential neighbor cells based on various criteria to identify high ranked neighbors. It evaluates the performance and characteristics of the serving cell, including signal strength, signal quality, interference levels, load, capacity, and other relevant parameters. This evaluation serves as a reference point for comparing potential neighbor cells. The source-target module (214) assesses the performance and suitability of potential neighbor cells based on various criteria. These criteria may include signal strength, signal quality, interference levels, load balancing requirements, coverage area, capacity, and operator-defined policies. The sourcetarget module (214) also compares the ranking or scores of potential neighbor cells with that of the serving cell. It identifies the neighbor cells that have a higher ranking or score, indicating their potential to provide better performance or coverage compared to the serving cell. It provides the ranking information to the handover decision process or network management systems. Based on the ranking results, the handover decision process can select the higher ranked neighbor cell as the target for handover, considering other factors such as handover policies, QoS requirements, and network conditions. The source-target module (214) adapts dynamically to changing network conditions and real-time updates. It continuously evaluates the performance of neighbor cells and updates the rankings based on the latest measurements. This ensures that the identification of higher ranked neighbors remains accurate and responsive to the dynamic nature of the network. The sourcetarget module is configured to rank the plurality of source-target pairs in descending order on basis of the percentage share of HO attempts.

[0074] In an embodiment, the system is further configured to analyse the one or more high ranked neighbor cells associated with each source cell to enable handover planning, cell compensation, and capacity planning. [0075] In an aspect of the present invention, the controller (104) is configured as the system (100-2) for high ranked neighbor cells identification in telecommunications network.

[0076] FIG. 3 illustrates an exemplary flow diagram (300) of an identification of high ranked neighbor cells, in accordance with an embodiment of the present disclosure.

[0077] As illustrated, in FIG. 3, an exemplary flow diagram (300) for the identification of high ranked neighbor cells is disclosed.

[0078] At step (302), the system (100-2) collects relevant measurements from the serving cell and neighboring cells. These measurements include signal strength, signal quality, interference levels, cell load, available capacity, and other performance metrics. The system (100-2) may also consider historical data and trends to supplement the real-time measurements. All the parameters and statistics are extracted from a Vendor Element Management System (EMS) for predefined time (e.g., every fifteen minutes).

[0079] At step (304), based on the collected measurements, the system (100-2) calculates various parameters that indicate the quality and suitability of neighbor cells. These parameters may include signal-to-interference ratio (SIR), signal-to-noise ratio (SNR), received power levels, cell load ratio, and other derived metrics that reflect the performance of neighboring cells. The KPIs related to the neighbor cells are computed by aggregation each hour. The system (100-2) assigns appropriate weights to the calculated parameters based on their significance and impact on the handover decision. The weights reflect the relative importance of each parameter in determining the ranking of neighbor cells. Additionally, the system (100-2) sets threshold values for each parameter to define the desired quality or performance level for a high-ranking neighbor cell. KPIs are also calculated for the source-target pair which includes the source or the current cell and the highest ranked neighboring cell.

[0080] As illustrated, in FIG. 3, at step (306), the system (100-2) computes daily neighbor related KPIs by aggregation of hourly data. KPIs are computed for all source-target pair. [0081] At step (308), the total handover (HO) attempts towards all the interfaces over a rolling period of 7 days are computed for each cell in service area. Total HO attempts for each cell = A.

[0082] At step (310), the total handover (HO) attempts towards all the interfaces over a rolling period of 7 days are computed for every source-target pair in a given service area. Total HO attempts per source-target pair = B.

[0083] At step (312), the handover share is computed as total HO attempts per source-target pair to total HO attempts for each cell. The percentage of handover shares contributed by each target-source pair is calculated. The formula is given by: percentage HO share = { 100* [(total HO attempts per Source-Target pair (B))/ (total HO attempts for each cell (A))] } .

[0084] At step (314), determining whether percentage share of HO contributed by a particular source-target pair > configurable number/certain threshold (e.g., 10 percentage).

[0085] At step (316), if the calculated percentage is higher than a certain threshold then the target cell is considered as a high ranked neighbor for the source cell.

[0086] At step (318), if the calculated percentage is not higher than a certain threshold then the target cell is not considered as a high ranked neighbor for the source cell.

[0087] At step (320), all the high ranked neighbors are stored in for each source cell is stored in the database (218). This can be used for a cell compensation in the case of any source cell outage to improve a user experience.

[0088] At step (322), all the high ranked neighbors are stored in for each source cell is stored in the database (218). The high ranked neighbors can also be used for capacity planning algorithms. This implementation will filter the potential neighbor relations for each of the cells depending upon the criteria and hence field team can focus their optimization activity on the cells which are having major share of attempts. Load Shifting, Parameter Related changes, Azimuth and Tilt related optimization activities can be planned easily depending on the potential neighbor information. [0089] As illustrated, in FIG. 3, a neighbor cell evaluation uses the calculated parameters and defined thresholds to evaluate each neighboring cell to determine its ranking. The system (100-2) compares the parameter values of each neighbor cell against the thresholds and assigns a ranking score or priority based on the compliance with the defined criteria. The system (100-2) also ranks the neighbor cells based on their evaluation scores or priorities. Cells that meet or exceed the threshold values for the defined parameters are assigned higher rankings. The system (100-2) may also consider additional factors such as network policies, load balancing requirements, or specific quality of service (QoS) criteria to further refine the ranking. Based on the rankings, the system (100-2) makes a handover decision, indicating the preferred high ranking neighbor cell for handover. The decision is communicated to the network management systems or mobile devices, which initiate the handover process to connect to the selected neighbor cell.

[0090] In an embodiment, the system (100-2) continuously monitors the performance of the selected neighbor cell after handover. It gathers feedback on signal quality, user experience, and network conditions to validate the accuracy of the handover decision. This feedback is used to refine the parameters, thresholds, and ranking algorithms in subsequent iterations. The system (100-2) is designed to adapt dynamically to changing network conditions. It continuously updates the measurements, recalculates the parameters, and adjusts the rankings based on realtime data. This ensures that the identification of higher-ranking neighbor cells remains accurate and responsive to the evolving network environment. By following this process flow, the system (100-2) can effectively identify higher ranking neighbor cells, enabling seamless handover and improving the overall performance and user experience in a telecommunications network.
