BACKGROUND [0002] Cellular Service Providers have started to deploy the Minimization of Drive Test (MDT) feature in the last few years. MDT calls are only 1-3% of the monitored traffic, which is sufficient to leverage machine learning algorithms. SUMMARY [0003] Systems and methods of this technical solution are directed to using machine learning algorithms to determine geolocation of mobile devices of a cellular network. [0004] At least one aspect is directed to a communication network monitoring device. The communication network monitoring device includes a processor and a memory. The memory includes instructions. The instructions, when executed by the processor, cause the device to receive, from a base station (BS), radio predictors of a first user equipment (UE) for which a minimization of drive test (MDT) mode is activated, a UE location history of the first UE, a geolocation of the first UE, radio predictors of a second UE for which the MDT mode is not activated, a UE location history of the second UE, and cell physical parameters. In some embodiments, the radio predictors of the first UE include a timing advance (TA) of the first UE and a channel quality indication (CQI) of the first UE, and wherein the radio predictors of the second UE include a TA of the second UE and a CQI of the second UE. The instructions, when executed by the processor, cause the device to train a machine learning (ML) model to determine an azimuth of the second UE at least based on the radio predictors of the first UE, the UE location history of the first UE, the geolocation of the first UE, and the cell physical parameters. The instructions, when executed by the processor, cause the device to execute the ML model to determine the azimuth of the second UE and provide, to a downstream application, a geolocation of the second UE at least based on the azimuth of the second UE and the TA of the second UE. 1 4865-4839-2561 Atty Dkt: 124395-2308 [0005] In some embodiments, the ML model that is executed to determine the azimuth of the second UE is trained using the TA of the first UE. In some embodiments, the instructions, when executed by the processor, cause the device to train the ML model using the TA of the first UE before training the ML model to determine the azimuth of the second UE. In some embodiments, the instructions, when executed by the processor, cause the device to execute the ML model that was trained using the TA of the first UE to generate a machine learning timing advance (MLTA) of the first UE. In some embodiments, training the ML model to determine the azimuth of the second UE includes training the ML model using the MLTA of the first UE, and executing the ML model to determine the azimuth of the second UE includes executing the ML model that was trained using the MLTA of the first UE to determine the azimuth of the second UE. [0006] In some embodiments, the instructions, when executed by the processor, cause the device to train a second ML model using the TA of the first UE before training the ML model to determine the azimuth of the second UE, wherein the ML model uses a first algorithm and the second ML model uses a second algorithm different from the first algorithm. In some embodiments, the instructions, when executed by the processor, cause the device to execute the second ML model that was trained using the TA of the first UE to generate a machine learning timing advance (MLTA) of the first UE. In some embodiments, training the ML model to determine the azimuth of the second UE includes training the ML model using the MLTA of the first UE. [0007] In some embodiments, the instructions, when executed by the processor, cause the device to determine an estimated distance between the BS and the second UE at least based on the TA of the second UE. In some embodiments, providing, to the downstream application, the geolocation of the second UE at least based on the azimuth of the second UE and the TA of the second UE includes providing, to the downstream application, the geolocation of the second UE at least based on the azimuth of the second UE and the estimated distance between the BS and the second UE. [0008] In some embodiments, providing, to the downstream application, the geolocation of the second UE at least based on the azimuth of the second UE and the TA of the second UE includes converting the azimuth and an estimated distance between the BS and the second UE at least based on the TA of the second UE into a latitude coordinate and a longitude coordinate and providing the latitude coordinate and the longitude coordinate to the 2 4865-4839-2561 Atty Dkt: 124395-2308 downstream application. [0009] In some embodiments, the ML model uses a plurality of decision trees. In some embodiments, the plurality of decision trees are used in accordance with the Random Forest algorithm. In some embodiments, the radio predictors of the first UE include a measurement report of the first UE, and wherein the radio predictors of the second UE include a measurement report of the second UE. [0010] In some embodiments, the measurement report of the first UE includes a serving cell Reference Signal Received Power (RSRP) of the first UE, a serving cell Reference Signal Received Quality (RSRQ) of the first UE, a neighbor cell RSRP of the first UE, a neighbor cell RSRQ of the first UE, and MDT data, and wherein the measurement report of the second UE includes a serving cell RSRP of the first UE, a serving cell RSRQ of the second UE, a neighbor cell RSRP of the second UE, and a neighbor cell RSRQ of the second UE. [0011] In some embodiments, the measurement report of the first UE includes a serving cell synchronization signal/physical broadcast channel (PBCH) block (SSB) index of the first UE, and a neighbor cell SSB index of the first UE, and wherein the measurement report of the second UE includes a serving cell SSB index of the second UE, and a neighbor cell SSB index of the second UE. [0012] At least one aspect is directed to a method to determine a geolocation. The method includes receiving, by a processor, from a base station (BS), radio predictors of a first user equipment (UE) for which a minimization of drive test (MDT) mode is activated, a UE location history of the first UE, a geolocation of the first UE, radio predictors of a second UE for which the MDT mode is not activated, a UE location history of the second UE, and cell physical parameters. In some embodiments, the radio predictors of the first UE include a timing advance (TA) of the first UE and a channel quality indication (CQI) of the first UE, and wherein the radio predictors of the second UE include a TA of the second UE and a CQI of the second UE. The method includes training, by the processor, a machine learning (ML) model to determine an azimuth of the second UE at least based on the radio predictors of the first UE, the UE location history of the first UE, the geolocation of the first UE, and the cell physical parameters. The method includes executing, by the processor, the ML model to determine the azimuth of the second UE and providing, by the processor, to a downstream application, a geolocation of the second UE at least based on the azimuth of the second UE and the TA of the second UE. 3 4865-4839-2561 Atty Dkt: 124395-2308 [0013] At least one aspect is directed to a non-transitory computer readable medium. The medium includes instructions stored thereon. The instructions, when executed by a processor, cause the processor to receive, from a base station (BS), radio predictors of a first user equipment (UE) for which a minimization of drive test (MDT) mode is activated, a UE location history of the first UE, a geolocation of the first UE, radio predictors of a second UE for which the MDT mode is not activated, a UE location history of the second UE, and cell physical parameters. In some embodiments, the radio predictors of the first UE include a timing advance (TA) of the first UE and a channel quality indication (CQI) of the first UE, and wherein the radio predictors of the second UE include a TA of the second UE and a CQI of the second UE. The instructions, when executed by the processor, cause the processor to train a machine learning (ML) model to determine an azimuth of the second UE at least based on the radio predictors of the first UE, the UE location history of the first UE, the geolocation of the first UE, and the cell physical parameters. The instructions, when executed by the processor, cause the processor to execute the ML model to determine the azimuth of the second UE and provide, to a downstream application, a geolocation of the second UE at least based on the azimuth of the second UE and the TA of the second UE. [0014] These and other aspects and implementations are discussed in detail below. The foregoing information and the following detailed description include illustrative examples of various aspects and implementations and provide an overview or framework for understanding the nature and character of the claimed aspects and implementations. The drawings provide illustration and a further understanding of the various aspects and implementations and are incorporated in and constitute a part of this specification.

DETAILED DESCRIPTION [0022] Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatus, and systems of correlating packets with synthetic transactions. For example, the methods, apparatus, and systems can provide a captured packet correlator that captures data packets communicated between a client application and a remote service to generate a packet capture file and uses finger-printing data to filter the packet capture file to retain filtered packets associated with synthetic transaction packets. The technical solution can provide the filtered packets to a data processing system to process the filtered packets in real-time in order to evaluate the performance of the services. The technical solution can isolate the data packets corresponding to the synthetic tests from other data packets when the data packets can lack associated metadata that indicates an originating process identifier (PID). The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways. [0023] Cellular Service Providers (CSPs) are to determine the geolocation of where each handset (a.k.a., User Equipment (UE)) makes each individual voice and data call (a.k.a., radio resource control (RRC) sessions, UE sessions) in their cellular network. The geolocation data can be used to optimize the operation of the cellular network, like coverage of individual cells and ensuring smooth handover performances other operation performances. In addition, CSPs may anonymize the traffic data and resell the traffic data to third parties for geo- marketing purposes. [0024] CSPs may not have access to UE geolocation information from Global Navigation Satellite Systems (GNSS) such as Global Positioning Systems (GPS) or information of nearby Wi-Fi or Bluetooth networks for geolocation purposes. For geolocation of UE sessions, CSPs may deploy systems that geolocation the cellular system radio signals. Cellular radio signals 5 4865-4839-2561 Atty Dkt: 124395-2308 that may be used are used in geolocation include one or more of timing advance (TA), Reference Signal Received Power (RSRP), of serving cell and neighbor cells, Reference Signal Received Quality (RSRQ) of serving cell and neighbor cells, or recent history of UE locations. The UE may regularly make measurement of the environment and send measurement reports of the radio signal when preconfigured conditions are met. The measurement reports may contain information such as serving cell and neighbor cell RSRP or RSRQ. [0025] Some geolocation systems can operate by combining the serving cell site antenna information (latitude and longitude coordinates of a cell site antenna, antenna characteristics (e.g., a horizontal and vertical beam width, a gain), a mount azimuth, a height above ground with the radio signal predictor information like one or more of RSRP, RSRQ of serving cell and neighbor cells, or a timing advance of serving cells. The serving and neighbor cell site information and radio predictor information can be combined to perform the best estimate of the geolocation of a UE session. [0026] CSPs have started to deploy the Minimization of Drive Test (MDT) feature in the last few years. In MDT, a small fraction of UE calls (a few percent) are activated with the MDT immediate mode feature or other mode that CSPs can use. When MDT immediate mode or other mode is activated and properly configured on a UE, when sending in a Measurement Reports the UE may provide the latitude/longitude geolocation coordinates as well. Under appropriate conditions, optional information such as altitude, velocity, and error estimation can be included in the measurement reports. [0027] The MDT data can provide a source of geolocation data that can be used as training data for a machine learning based geolocation system. Using MDT geolocation as training data, a machine learning system can be developed to predict the latitude and longitude coordinates of any UE RRC Session using the cell information and radio predictors as input to the ML geolocation algorithm. [0028] However, some implementations of ML (e.g., a direct Random Forest implementation) that directly predict the latitude and longitude coordinates have been shown to be very resource intensive. In a large metropolitan market cellular system, there are often thousands of cells. A machine learning model is required for each cell. A large number of (e.g., up to 20 million) RRC Connections may need to be geolocated per hour. To train an ML model, thousands of calls from many different UEs may be needed. A direct ML 6 4865-4839-2561 Atty Dkt: 124395-2308 implementation to predict the latitude and longitude coordinates of every radio resource connection (RRC) may require a significant amount of random access memory (RAM) to store the ML models for each cell and significant central processing unit (CPU) resources to execute the Random Forest algorithm. [0029] Disclosed herein are embodiments of a system and method to transform the geolocation problem space from a rectangular (e.g., latitude and longitude) coordinate system into the cell site view of distance (e.g., range) and azimuth coordinate space. Embodiments of the system and method may be applied to predict the range of a UE session independently of the azimuth. A Random Forest machine learning algorithm may be applied to determine the azimuth of a UE session, which is a one-dimensional variable. The resulting Random Forest tree structure may contain significantly less nodes and tree depth than the original two- dimensional problem required for the same accuracy. [0030] When in polar coordinate, the two-dimensional geolocation problem can be reduced into two one-dimensional problems. The range problem may have a computational very efficient solution (e.g., by using the TA provided by the base station), and the azimuth problem may have a significantly simpler machine learning solution compared to traditional two-dimensional machine learning problems. Some embodiments of a system and method reduce the overall computational complexity of the machine learning geolocation for cellular systems. [0031] Disclosed herein are embodiments of a system and method for a two-stage approach to solving the geolocation problem. In the first stage, “timing advance (TA) correction model” is created, can be adjusted, and is called as Machine Learning Timing Advance (MLTA). The MLTA can be processed in the next stage by the next “Geo prediction model” along with the list of other attributes. [0032] Contrary to the older “fixed/ mathematical” methodology, the ML approach may be adaptable to each cell site. In other words, each cell site may have unique radio and cell site attributes which over a period of time changes, like new buildings that are constructed or tree growth, thus creating new radio patterns (e.g., obstructing the radio signals). This can result in changed MDT data. However the models for each cell are also adapted in real time, which was not possible with the older “fixed/ mathematical” methodology. [0033] FIG. 1 schematically illustrates a mobile (cellular) communication system 10, in which users of a plurality of mobile communication devices (also referred to herein as user 7 4865-4839-2561 Atty Dkt: 124395-2308 equipments (UEs)) 20 can communicate with other users. The communication system 10 includes a cell site 36. The cell site 36 can be a physical site of a cell tower. As shown in FIG.1, the cell site 36 includes (e.g., hosts) a number of cells 30, 32, and 34. However, one skilled in the art readily recognizes the communication includes any number of suitable cells. In some embodiments, each of the cells 30-34 can be a different frequency or azimuth in the cell site 36. In a first example, the cell 30 faces north with azimuth of 0 degrees (from north), the cell 32 faces southeast with an azimuth of 120 degrees (from north), and the cell 34 faces southwest with an azimuth of 240 degrees (from north). This can be referred to as a 3-sector site. In a second example, the cell 30 has 12 cells, or four 3-sector sites, each operating at a different radio frequency. [0034] A base station is equipment supporting (e.g., serving) a cell site (e.g., a cell of the cell site). For example, in FIG. 1, a base station 35A supports the cell 30, a base station 35B supports the cell 32, and a base station 35C supports the cell 34. In some embodiments, more than one base station can support a cell. In some embodiments, a base station can support more than one cell or cell site. Each cell can include an antenna. Each base station can include an antenna. [0035] The UE 20 can communicate to other users via a suitable cellular radio access network (RAN) and a respective core network (CN). In the case of 3G, the cellular RAN is a Universal Mobile Telecommunications Service (UMTS) RAN (UTRAN) and the CN is a UMTS CN. In the case of 4G, the cellular RAN is a Long-Term Evolution (LTE) RAN (E- UTRAN) and the CN is an Evolved Packet Core (EPC). In the case of 5G, the cellular RAN is a Next Generation (NG) RAN (NG-RAN) and the CN is a 5G CN (5GC). In some embodiments, the RAN is a cloud-based RAN such as a centralized RAN (CRAN) or Open RAN (ORAN). [0036] As one skilled in the art would readily recognize, the communication system 10 includes one or more RANs. A RAN covers one or more cell sites such as the cell site 36. In some embodiments, a RAN includes a plurality of smaller RANs with interconnect. For example, a non-standalone (NSA) NG-RAN includes an NG-RAN and an E-UTRAN. [0037] Each RAN includes one or more base stations. The type of base station depends on the type of RAN. For instance, a base station of a UTRAN includes a ‘NodeB,’ a base station of an E-UTRAN includes an ‘evolved NodeB’ (eNB), and a base station of an NG-RAN includes a ‘Next Generation NodeB’ (gNB). The UTRAN base station further includes 8 4865-4839-2561 Atty Dkt: 124395-2308 typically a Radio Network Controller (RNC). The radio network control functionality of the E-UTRAN and the NG-RAN is integrated typically with the base station functionality in the eNB and the gNB, respectively. [0038] In an embodiments of a UTRAN, each of the base stations 35A-35C are NodeBs. In some embodiments of a E-UTRAN, each of the base stations 35A-35C are eNodeBs. In some embodiments of an NG-RAN, each of the base stations 35A-35C are gNodeBs. In some embodiments of an NG-RAN, the base stations 35A-35C are some combination of two or more of NodeBs, eNodeBs, and gNodeBs. In some embodiments of a cloud-based RAN, a base station can serve multiple cell sites. [0039] A UE engaged in a call is served by a cell. As shown in FIG. 1, the cell 30 is the serving cell that serves the UE 20. A neighbor cell can be another cell on the same cell site as the serving cell. As shown in FIG. 1, the cells 32 and 34 are the neighbor cells with reference to the UE 20 and the cell 30. The neighbor cells are not limited to the cells in a same cell site as the serving cell. [0040] It is to be appreciated that the UE devices 20 of the communication system 10 can employ Minimization of Drive Test (MDT) procedures for minimizing drive test requirements in which selected UEs 20 (typically 1-3% of all UEs in the communication system 10) acquire appropriate Global Positioning System (GPS) location measurements and data from a GPS system 40 and report them to the system 10 with, where appropriate, associated location information (e.g., GPS data). [0041] In accordance with the preferred embodiments, communicatively coupled to the cellular communication system 10 is a communication network monitoring device 50, such as the TrueCall® system commercially available from NetScout. The network monitoring device 50 may be operable and configured to monitor incoming signaling call records from UEs 20 in the communication system 10 to provide enriched and actionable RAN data which may be utilized to diagnose network and UE problems in real-time, understand demand density and usage, support traffic pattern analysis for network capacity planning, geolocate dropped calls, minimize drive testing and gain an end-to-end view from the radio network to the IP Multimedia Subsystem (IMS) core. In particular, the network monitoring device 50 can provide real-time analysis of data originating in the RAN(s) (e.g., the RAN(s) of cell site 36). The data may be enriched using the geolocation algorithm of the network monitoring device 50 and correlated with subscriber and device data enabling insight into the 9 4865-4839-2561 Atty Dkt: 124395-2308 performance of the RANs by combining dimensions of a RAN operation in a single location, as further discussed herein. Exemplary features and functionality of the network monitoring device 50 include but are not limited to: diagnose network and device 20 problems in real- time; identify demand density and drill down to map usage; study traffic patterns; and geolocate calls and minimize drive testing as discussed herein with reference to the described illustrated embodiments. [0042] It is to be appreciated that incoming signaling record 55 of a number of UEs such as the UE 20 is received and monitored by the network monitoring device 50. Such an incoming signaling record 55 may include one or more of radio predictors (a.k.a., radio signal attributes) of the UE 20, UE location history of the UE 20, or cell physical parameters for each cell of one or more cells (e.g., the cell 30, the cell 32, and/or the cell 34). The radio predictors can include physical layer (a.k.a., layer 1) information such as one or more of Timing Advance (TA) signal of the UE 20 or a channel quality indication (CQI) of the UE 20. The cell physical parameters may include one or more of antenna azimuth, latitude/longitude location, mounting height, an antenna horizontal and vertical beam width, an antenna boresight direction, and an antenna gain or signal transmit power. [0043] The radio predictors can include radio resource control (RRC) layer (a.k.a., layer 3) information embodied in a measurement report. The measurement report may include one or more of a signal strength value of a serving cell for the UE 20 (e.g., a Reference Signal Received Power (RSRP) signal value); a signal quality value of a serving cell for the UE 20 (e.g., a Reference Signal Received Quality (RSRQ) signal value); a signal strength value of a neighboring cell relative to the serving cell for the UE 20; a signal quality value of a neighboring cell relative to the serving cell for the UE 20. In the case of 5G, the measurement report may include a serving cell synchronization signal/physical broadcast channel (PBCH) block (SSB) index of the UE 20, and a neighbor cell SSB index of the UE 20. In the case that Minimization of Drive Test (MDT) mode is activated for the UE 20, the measurement may include a data record of the UE 20. [0044] The incoming signaling record 55 can include different types of information for different UEs. For example, the incoming signaling record 55 can include TA, CQI, and UE location history for a first UE, TA, CQI, UE location history, and a non-MDT measurement report for a second UE, and a TA, CQI, UE location history, and an MDT measurement report for a third UE. 10 4865-4839-2561 Atty Dkt: 124395-2308 [0045] The network monitoring device 50 can store the incoming signaling record 55 in various ways. For example, the physical parameters of each cell of the incoming signaling record 55 can be stored into a data structure (e.g., a matrix, a table, a network element table). The data structure can include a plurality of structures of a first dimension (e.g., rows) and a plurality of structures of a second dimension (e.g., columns). Each cell can be associated with a structure in the first dimension and a physical parameter of the incoming signaling record 55 can be associated with a structure in the second dimension. For example, each row can be assigned to one cell, and each column can be assigned to one of the physical parameters. Thus, a first parameter of a first cell can be stored in the data structure in a location corresponding to the row assigned to the first cell and the column assigned to the first physical parameter. [0046] It is to be understood the TA signal value in a cellular communication system 10 corresponds to the length of time a signal takes to reach a base station 35 from a communicating UE mobile phone 20. For instance, a Global System for Mobile (GSM) uses Time-division multiple access (TDMA) technology in the radio interface to share a single frequency between several users, assigning sequential timeslots to the individual users sharing a frequency. Each user transmits periodically for less than one-eighth of the time within one of the eight timeslots. Since the users are at various distances from the base station and radio waves travel at the finite speed of light, the precise arrival-time within the slot can be used by the base station to determine the distance to the mobile phone. The time at which the phone is allowed to transmit a burst of traffic within a timeslot may be adjusted accordingly to prevent collisions with adjacent users. Timing Advance (TA) is the variable controlling this adjustment. It is to be appreciated that Timing Advance is significant for privacy and communications security, as its combination with other variables can allow the mobile communication system 10 to find the device's position and track the mobile phone user. TA may also be used to adjust transmission power in space-division multiple access systems. [0047] FIG.2 is an illustration of a method 200 of receiving and processing a signaling record (e.g., the incoming signaling record 55) to determine a geolocation of a UE (e.g., the UE 20) in accordance with an implementation. The method 200 can be performed by one or more system, component or module depicted in FIG. 1 or FIG. 6, including, for example, a communication network monitoring device (e.g., communication network monitoring device 50), or one or more processors of any of the above. Additional, fewer, or different operations 11 4865-4839-2561 Atty Dkt: 124395-2308 may be performed in the method 200 depending on the embodiment. Additionally, or alternatively, two or more of the blocks of the method 200 may be performed in parallel. [0048] In some embodiments, at operation 205, the communication network monitoring device determines whether there is a signaling record to be received. In some embodiments, in response to determining that there is a signaling record to be received, the communication network monitoring device proceeds to operation 210, and in response to determining that there is not a signaling record to be received, the communication network monitoring device proceeds to operation 215. [0049] At operation 210, the communication network monitoring device receives the signaling record. The communication network monitoring device can receive the signaling record from a base station (e.g., the base station 35). As described above, the signaling record can include UE data and cell data corresponding to a number of UEs that are in a call (e.g., for which an RRC session has been established). That is, data from a number of UEs can be batched into a signaling record that is sent to the communication network monitoring device. In some embodiments, the signaling record is stored in a storage or memory of the communication network monitoring device. [0050] In some embodiments, at operation 215, the communication network monitoring device determines if a predetermined time has elapsed. The predetermined time is set to periodically allow training of a machine learning (ML) model in the communication network monitoring device. In some embodiments, in response to determining that the predetermined time has elapsed, the communication network monitoring device proceeds to operation 220, and in response to determining that the predetermined time has not elapsed, the communication network monitoring device proceeds to operation 225. [0051] At operation 220, the communication network monitoring device trains the ML model using a number of signaling records received by the communication network monitoring device. In some embodiments, the communication network monitoring device uses UE and cell data corresponding to UEs that include have GPS data or other geolocation data in order to train the ML model. In some embodiments, the communication network monitoring device uses UE and cell data corresponding to UEs that include have MDT mode activated in order to train the ML model. For example, data corresponding to a UE with MDT mode activated may include radio predictors, UE location history, and cell physical parameters. The radio predictors may include MDT data indicating the geolocation of the corresponding UE with 12 4865-4839-2561 Atty Dkt: 124395-2308 MDT mode activated. In regards to training the ML model, in some embodiments, the communication network monitoring uses UE and cell data corresponding to UEs that do not have geolocation data (e.g., GPS data, MDT mode activated, etc.) to train the ML model, whereas, in some embodiments, the communication network monitoring ignores or otherwise does not use UE and cell data corresponding to UEs that do not have geolocation data (e.g., GPS data, MDT mode activated, etc.). [0052] In some embodiments, the communication network monitoring device checks for validity of the GPS data or other geolocation data of the (e.g., MDT-activated) UE before using it for ML model training. For example, a UE many report MDT data (e.g., GPS location data) that disagrees above a threshold with some or all the other radio predictors. In these cases, the communication network monitoring device may not use the MDT data of that UE for ML model training. In some embodiments, checking for validity includes ensuring the GPS latitude and longitude fields are present with valid ranges (e.g., have not been corrupted); ensuring the MDT accuracy fields are present with an accuracy according to a threshold range (e.g., 1 to 100 meters); and/or ensuring the MDT speed field is present, and preferably with a positive range. [0053] At operation 225, the communication network monitoring device determines whether the model is trained. In some embodiments, in response to determining that the model is trained, the communication network monitoring device proceeds to operation 230, and in response to determining that the ML model is not trained, the communication network monitoring device proceeds to operation 240. [0054] At operation 230, the communication network monitoring device determines whether the signaling record includes data and cell data corresponding to UEs for which a geolocation is unknown (e.g., UEs for which MDT mode is not activated and no GPS data or other geolocation is available, such as a second instance of the UE 20). In some embodiments, in response to determining that the signaling record includes data and cell data corresponding to UEs for which a geolocation is unknown, the communication network monitoring device proceeds to operation 235, and in response to determining that the signaling record does not include data and cell data corresponding to UEs for which a geolocation is unknown, the communication network monitoring device returns to operation 205. [0055] At operation 235, the communication network monitoring device executes the ML model on the UEs for which a geolocation is unknown in order to determine the geolocation. The ML model can use one or more of the radio parameters, UE location history, or the cell 13 4865-4839-2561 Atty Dkt: 124395-2308 physical parameters associated with a UE for which a geolocation is unknown as inputs to the ML model. In some embodiments, the ML model determines an azimuth for the UE for which a geolocation is unknown as inputs to the ML model and leverages a TA that is included as part of the radio predictors for that UE. In some embodiments, the ML model uses the inputs to adjust the TA to a machine learning timing advance (MLTA), trains the ML model (or a second ML model) with the MLTA, and executes the ML model (or the second ML model) to determine the azimuth for the UE for which a geolocation is unknown as inputs to the ML model. In some embodiments, the ML model uses the inputs to adjust a TA-derived distance to a machine learning an MLTA-derived distance. [0056] At operation 240, the communication network monitoring device executes a traditional fixed algorithm on the UEs for which a geolocation is unknown in order to determine the geolocation without use of a ML model. In response to completing operation 235 or 240, the communication network monitoring device proceeds to operation 245. [0057] At operation 245, the communication network monitoring device provides the geolocation to a downstream application. The downstream application can be an application of a cellular service provider (CSP) or a third-party application. The geolocation data can be used to optimize the operation of the cellular network or for geo-marketing purposes. In some embodiments, the communication network monitoring device converts the azimuth and a timing advance distance to a latitude and longitude and provides the latitude and longitude to the downstream application. In some embodiments, the communication network monitoring device provides the azimuth and the timing advance distance to the downstream application. [0058] The timing advance distance is understood to be the distance between a base station and the UE for which a geolocation is unknown as inputs to the ML model. As discussed above, the timing advance distance can be determined using the TA (or the MLTA) and the speed of light. For example, the timing advance distance can be calculated as half of a product of the speed of light and the TA (or the MLTA). The factor of 2 can account for the round trip. In some embodiments, the timing advance distance can be received as part of the measurement report. [0059] The communication network monitoring device 50 can determine a geolocation of a number of UEs using a machine learning (ML) geolocation algorithm. The ML algorithm can include a neural network such as tensor flow. The neural network is more accurate but at the expense of being slower to execute and more central processing unit (CPU) intensive. 14 4865-4839-2561 Atty Dkt: 124395-2308 An appropriate use-case for neural networks may be image recognition. The ML algorithm can include a regression algorithm, such as a tree-based model, linear regression, or multi- regression. Linear and multi-regression are more appropriate for where a coefficient may be determined but less appropriate for deciphering complex trends. A tree-based model such as the random forest algorithm may be used to determine a geolocation of a number of UEs. The random forest algorithm is less CPU intensive, moderate for random access memory (RAM) utilization, and quicker in executing than a neural network model. The Random Forest can be used for highly intensive processing, real-time applications. [0060] The geolocation problem can be broken down into two one-dimensional problems – solving for the distance of a UE and solving for the azimuth of UE. The complexity (number of nodes and number of layers) of the decision trees in the Random Forest required to determine the one-dimensional azimuth is significantly less than apply Random Forest directly to determination of latitude longitude coordinates. The random forest for azimuth execution can require much less CPU and memory (tree size) resources. [0061] In some embodiments, the communication network monitoring device 50 uses the distance in the signaling record 55 or uses the TA in the signaling record to calculate the distance, and the communication network monitoring device 50 uses the Random Forest algorithm can be used to determine the azimuth of one or more UEs, although other ML algorithms are within the scope of the present disclosure. In some embodiments, the communication network monitoring device 50 uses the Random Forest algorithm separately to determine the MLTA. Using a same type of ML model for both variables may simplify implementation of the communication network monitoring device 50. In some embodiments, the communication network monitoring device 50 uses linear regression or multi-regression to determine the MLTA. Using a simpler ML model for the distance may reduce CPU utilization, RAM utilization and latency of the communication network monitoring device 50. [0062] FIG.3 is an illustration of a diagram 300 of determining an azimuth using a Random Forest algorithm, in accordance with an implementation. The diagram 300 includes a UE-to- cell site distance 305. In some embodiments, the UE-to-Cell site distance is set to the TA distance. In some embodiments, the UE-to-Cell site distance is set to the MLTA distance. The diagram 300 includes predicted azimuths 310 of the individual trees in a Random Forest Algorithm. The diagram 300 includes a predicted azimuth 315, which can be represented as 15 4865-4839-2561 Atty Dkt: 124395-2308 a mean azimuth of all predicted azimuths 310. The azimuth can be understood as an angle from the North 320.
