25 [0004] In the telecom age, the performance of a network plays a vital role
in analyzing the capabilities of the underlying network infrastructure. The network
performance depends on several factors, for example, the number of user devices
serviced by the network. With the exponentially growing number of user devices,
there is a strain associated with the network to service them, resulting in a
30 degradation in the performance of both the network and the devices.

[0005] In order to address the performance of devices and the network,
network service providers, device manufacturers, and software providers play an
important role by enabling the collection of different parameters associated with the
device and network and evaluating a performance of the devices in the network.
5 [0006] However, there is still a scope of development of monitoring the
performance of the devices in the network for optimization of resources.
[0007] 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.

[0066] In an exemplary embodiment, a cell site (102) for performing device
analytics is selected. Further, the selected cell site (102) is divided into a number of 5 grids (104). In an example embodiment, the grids (104) may include a 5x5 meter grid. The grid size may be selected as per required output quality, for example, smaller the grid better the bench marking quality.
[0067] In an exemplary embodiment, the system (110) checks for the
availability of samples from at least two different user devices (106) and whether
10 all the user devices are connected to the network (108) from a single cell site (102). If the above criteria are satisfied, the system (110) may check for one or more parameters associated with the user device (106) and may evaluate an average value of samples associated with a particular grid for each type and make of user device (106). In some embodiments, the system (110) may evaluate a mean, minimum, or

user device (106-1) with parameter value and assign score 1 to the first user device (106-1). Similarly, the system (110) may identify a second user device (106-2) with the lowest parameter value and assign a score of 0 to the second user device (106-
25 2). For the other user devices for which the parameter value falls in between best and lowest, the system (110) may assign a score(s) based on the score step defined for the respective parameters. Further, the system (110) may store parameter values for each model of the user device (106) along with the number of samples for further calculations, and the system (110) may repeat the above steps in a single grid (104-
30 1) till all the parameters are evaluated. In an exemplary embodiment, the system
15

(110) may check for remaining grids (104) that are not evaluated through the above
steps and repeat all steps for all possible grids (104) in the cell site (102).
[0069] In an exemplary embodiment, the evaluation unit (114) may
calculate a score for each key performance indicator (KPI) for each make and model 5 of user devices (106) as sum grid score * 100/ sum of samples and a final score for each make and model is evaluated as (Sum (KPIi Score * Weight+ KPIn * Weight n)), wherein the weight factors are predefined.
[0070] In an exemplary embodiment, the system (110) may select the user
device (106) or handset with highest score as best performing handset and the user
10 device (106) with the lowest score as poor performing handset. In an exemplary embodiment, the weight factor of respective parameters as per algorithm settings and the weight factor and score may be configurable.
[0071] FIG. 2 illustrates an exemplary block diagram representation (200)

[0077] A person of ordinary skill in the art will appreciate that the
exemplary block diagram (200) may be modular and flexible to accommodate any kind of changes in the system (120).
20 [0078] FIG. 3 illustrates an exemplary flow chart for a method (300) for
evaluating performances of user devices (106) in the network (108), in accordance with embodiments of the present disclosure.
[0079] In some embodiments, a method (300) for evaluation of the user
devices (106) in the network (108) of FIG. 1 served by same cell identifier (ID)
25 may be achieved by evaluating unique KPI from a plurality of KPIs, in each of active multi-vendor user devices (106) in a specific grid (104) and determining a score based on one or more pre-defined rules.
[0080] In some embodiments, the method (300) may include, at step 302,
creating a grid (e.g., 104) at a cell site (e.g., 102). The method (300) may include,
30 at step 304, receiving a pre-defined grid size input for creating the grid (104). In
18

some embodiments, the cell site (102) may be divided into one or more grids (104) based on the grid size input.
[0081] In some embodiments, the method (300) may further include, at step
306, selecting a top north grid. In some embodiments, any grid other than the top 5 north grid may be selected. Further, in some embodiments, the method (300) may include, at step 308, receiving all the samples associated with a data from the selected grid. In some embodiments, the samples may include signal information from one or more user devices (106) from different manufacturers. In some embodiments, the method (300) may further include, at step 310, determining if the
10 received samples are from more than one make and model, for example, the samples may be from two different mobile device manufacturers, or may be different models from the same manufacturer. If the samples are not from two different manufacturers or two different models, the samples may not be evaluated and the method (300) may include, at step 348, ending the process. On the other hand, if
15 the samples are from two different manufacturers or models, the method (300) may include, at step 312, determining if the samples are associated with a same cell ID, for example, all the user devices (106) may belong to the same cell. If the samples are not associated with the same cell ID, the method (300) may include, at step 348, ending the process.
20 [0082] On the other hand, if the samples are associated with the same cell
ID, the method (300) may include, at step 314, selecting a first KPI from a list of KPIs for which the user device (106) needs to be evaluated. In some embodiments, the method (300) may include, at step 316, providing a list of KPIs to be evaluated along with respective threshold values. Further, the method (300) may include, at
25 step 318, determining if the KPI value is within a predefined threshold. If the KPI value is less than the predefined threshold, the method (300) may include, at step 322, identifying the make and model of the corresponding user device (106) having the best value and assigning a score value of "1" to the user device (106) for that particular KPI. On the other hand, if the KPI value is more than the predefined
30 threshold, the method (300) may include, at step 320, assigning a score value of "0" to the particular handset or user device (106) for the particular KPI. In some
19

embodiments, all the received samples may be from more than one category of user devices served within the grid by the same cell for that particular KPI. The particular handset or user device (106) is related to one particular/specific make and model. The particular KPI is related to one specific parameter e.g., a reference 5 signal received power (RSRP), a signal to interference and noise ratio (SINR), a channel quality indicator (CQI), a reference signal received quality (RSRQ), call drop, call mute, and uplink (UL) interference, etc. The make and model refers to a company/manufacturer that makes a user device, and the user device's model is the user device's specific name. The method (300) may further include, at step 324,
10 assigning a score value between "0" and " 1" for all other user devices (106) in steps (i.e., the user devices other than the user device with score "0" or "1") based on receiving a score offset input for the particular KPI at step 326. The method (300) may include, at step 328, calculating a grid score based on multiplying the number of samples with the KPI score for all the user devices within the selected grid. The
15 method (300) may further include, at step 330, determining if all the KPIs within
the selected grid are evaluated. If all the KPIs within the selected grid are not
evaluated, the method (300) may include, at step 332, selecting the next KPI and
proceeding with the iterations from step 318.
[0083] On the other hand, if all the KPIs within the selected grid are
20 evaluated, the method (300) may include, at step 336, determining if all the grids
within a selected cell site (102) or geographical area are evaluated. If all the grids
are not evaluated, the method (300) may include, at step 334, selecting a grid that
is not evaluated and proceeding with the iterations from step 308.
[0084] On the other hand, if all the grids within the selected cell site (102)
25 are evaluated, the method (300) may include, at step 338, calculating each KPI score for each user device as KPI score for user device = ((sum grid score *100)/sum of samples). The method (300) may further include, at step 340, calculating a final score associated with the user device as final score = Sum (KPI1 Score * Weight+ KPI n) Weight n), based on obtaining, at step 342, weights for calculating a final
30 score for each KPI. The method (300) may further include, at step 344, sorting the user devices (106) based on the final score and marking, at step 346, the user device
20

with the highest score as best performing user device and the user device with the lowest score as poor performance user device. In some embodiments, the weights and thresholds may be preconfigured.
[0085] In an example embodiment, for performing the method (300), the
5 disclosed system (e.g., 110) creates a 5X5 meter grid for a given cell site and considers the samples received based on user-measured and reported sample data for pre-defined days (e.g., 15 days). Further, the samples may be considered for scoring if they are associated with user devices with different manufacturers or different models and the user devices are served by the same cell ID, other samples
10 may not be considered for scoring. Further, a particular KPI for comparison may be considered only if samples present for each user device (different make and model) are reported in that grid, else the KPIs may not be considered. In an aspect, the failure KPIs are excluded in this condition. Further, rest of the samples who not fulfilled above conditions will not be consider. An average of all samples of
15 particular make and model is calculated.
[0086] In some embodiments, the KPI may include such as, without
limitations, at least one of reference signal received power (RSRP), signal to interference and noise ratio (SINR), channel quality indicator (CQI), reference signal received quality (RSRQ), call drop, call mute, and uplink (UL) interference
20 etc. A person of ordinary skill in the art will appreciate that the KPI and parameters are not limited to the ones mentioned in the disclosure but may include any KPI/parameters associated with wireless communication system. Thus, a comparison between the KPIs of different makes and models can be obtained. Further once a particular KPI is available for comparison within grid then scoring
25 of the KPI for each make and model can be performed.
[0087] In an example embodiment, the score range for any of the KPIs
associated with the user device (106) may include marking the best as 1, worst as 0, and the values in between based on pre-defined steps between 1 and 0. The KPI score may be calculated for all the samples in a grid to obtain a grid score. The grid
30 score may then be multiplied by the weight associated with the KPI to obtain the final score for a particular make and model of the user device (106). The final score
21

provides a ranking of that make and model for a selected geography (geographical
region). In some embodiments, the weights and scores may be configurable. In an
embodiment, one or more devices may be categorized based on performance. The
categorization may be based on the evaluation of the device in the network.
5 Furthermore, the categorization may be based on user-defined scoring criteria.
[0088] In an example embodiment, the following scoring steps are
followed:
[0089] In an aspect, score range for RSRP is revised as: - mark best as 1,
anything worse than 10 db as 0 and in between values should define in step of 0.1
10 from higher to lower i.e. if best is -75 then tag it as 1, -76 as 0.9, -77 as 0.8 etc to -85 as 0.
[0090] In an aspect, score range for SINR/CQI/RSRQ is revised as: best as
1, anything 3 db lower as 0 and in between them as 0.7 (near to best) and 0.35 (for remaining value).
15 [0091] In an aspect, for drop and mute consider the exact value. If TA
distance is within 300 metre and UE power headroom having value < 0, then it may be considered that UE is causing uplink (UL) interference and may count exact such instances for each handset who identified as UL interference source. The power headroom is a mechanism used by User Equipment (UE) to report its available
20 transmit power to the base station (eNodeB) in the LTE network.
[0092] In an aspect, the total samples for RSRP/SINR/CQI/RSRQ in grid is
obtained. In an aspect, the total samples for drop calls and mute calls i.e., nothing but total calls, the sum of (NE35, NE36, NE22, NE21, NE20, NE6, NE5, NE4, NE3) all these events in grid is considered. Here, NE are the events associated with
25 the drop calls/mute calls. Further, perform multiplication of RSRP/
SINR/CQI/RSRQ samples and a score is obtained as per first step for the grid. Sum
all samples and sum (multiplication of RSRP/ SINR/CQI/RSRQ samples and score)
for specific make and model for geography.
[0093] In an aspect, similarly, perform sum of drop calls/mute calls and sum
30 of samples of drop calls/mute calls i.e. sum of events (NE35, NE36, NE22, NE21, NE20, NE6, NE5, NE4, NE3) for specific make and model for geography. In an
22

aspect, the final score for RSRP is (SUM (multiplication of RSRP/ SINR/CQI/RSRQ samples and score) / SUM (RSRP/ SINR/CQI/RSRQ samples)) *100.
[0094] In an aspect, the final score for drop/mute is 100-(SUM (Drop
5 calls/mute calls)/SUM (samples)* 100)
[0095] In an aspect, once the final score for a KPI is available, then the final
score is multiplied by the corresponding weightage of that KPI to get a ranking of that make and model for selected geography. For example, RSRP weightage is 3.5, CQI /RSRQ/SINR weightage is 2.5, UL interference weightage is 2, call drop
10 weightage is 1.25, and call mute weightage is 0.75. In some aspects, the weightage and score need to be configurable.

[0100] FIG. 5 illustrates an exemplary flow chart for a method (500) for
evaluating the performances of devices in the network (108) in accordance with embodiments of the present disclosure.
20 [0101] At step 502, a grid is created as per input grid size defined in step
504.
[0102] At step 506, it is checked if the samples within grids are more than
1 make and model. The process ends when step 506 is non-affirmative.
[0103] At step 508, when step 506 is affirmative, it is checked if the samples
25 within grids are served by the same cell ID or not. The process ends when step 508 is non affirmative.
[0104] At step 510, when the step 508 is affirmative, it is checked if the
samples from more than 1 make and model are available for particular Radio Frequency (RF) key performance indicator (KPI).
30 [0105] At step 512, when the step 510 is non-affirmative, that KPI is not
considered.
24

[0106] At step 514, when the step 510 is affirmative, a set of particular KPI
is selected. The particular KPI is related to one specific parameter e.g., a reference signal received power (RSRP), a signal to interference and noise ratio (SINR), a channel quality indicator (CQI), a reference signal received quality (RSRQ), call 5 drop, call mute, and uplink (UL) interference etc.
[0107] At step 516, in order to perform step 514, the KPI are feed and
threshold for corresponding KPI which should consider e.g., KPI RSRP with
threshold of lOdb is fed.
[0108] At step 518, the best user device of a defined make and model in that
10 grid is found for that particular/particular KPI, and it is scored as 1.
[0109] At step 520, the make and models who all are having corresponding
KPI value beyond the threshold should tag the score as 0.
[0110] At step 522, make and models whose KPI value lies between the
defined threshold and best in that grid should mapped with score in steps between
15 1 to 0 as per the descending value of the KPI.
[0111] For example, for RSRP: - Identify best make and model in that grid
and score it as 1 and anything worse than 10 db as 0 and in between values should define in step of 0.1 from higher to lower, i.e., if best is -75 then tag it as 1, -76 as 0.9, -77 as 0.8 etc to -85 as 0.
20 [0112] For example, for CQI/RSRQ/SINR: - Identify the best make and
model amongst all and will score it as 1, anything 3 db lower as 0 and in between them as 0.7(near to best) and 0.35 (for remaining value).
[0113] For example, for Call drop and Call Mute: - Will score -1 for each
handset who is having call drop / call mute.
25 [0114] For example, for UL interference: - If timing advance distance is
within define distance and the user equipment (UE) power headroom having value
< 0, then will consider that UE is causing uplink (UL) interference and will score -
1.
[0115] At step 524, multiply the samples and score of particular KPI for that
30 make and model in grid and tag it as grid score.
25

[0116] At step 526, add all the grid score and total samples in all grids of
particular KPI for that make and model in selected geography.
[0117] At step 528, calculate final score of particular KPI for make and
model in selected geography as, sum of grid score* 100/sum of samples.
5 [0118] At step 530, multiply the final score of the KPI of particular make
and model with the weightage of that KPI to calculate the ranking of that make and
model in selected geography.
[0119] At step 532, define weightage of each KPI.
[0120] At step 534, higher the rank means that make and model is best
10 performing in that selected geography.
[0121] FIG. 6 illustrates another exemplary flow chart for a method for
evaluating performances of devices in the network, in accordance with
embodiments of the present disclosure.
[0122] At 602, the method comprises identifying a geographical region.
15 [0123] At 604, the method comprises identifying one or more user devices
communicatively coupled to the network in the geographical region.
[0124] At 606, the method comprises receiving a sample data related to one
or more parameters associated with the one or more user devices.

or more user devices using the one or more parameters based on a processing of the 25 sample data, the threshold value, and the weightage value corresponding to each
parameter.
[0128] At 614, the method comprising evaluating the performance of the
one or more user devices based on the calculated score.
[0129] In an exemplary embodiment, the present invention discloses a
30 system for evaluating performance of one or more user devices in a network. The

26

or more parameters associated with one or more user devices and receive a threshold value related to each parameter of the one or more parameters for the evaluation.

A processing unit coupled to the receiving unit and the database and is configured to identify a geographical region and identify the one or more user devices communicatively coupled to the network in the geographical region. The processing unit is configured to obtain a weightage value associated with each parameter, calculate a score for
10 each of the one or more user devices using the one or more parameters based on a
processing of the sample data, the threshold value, and the weightage value
corresponding to each parameter and evaluate the performance of the one or more
user devices based on the calculated score.
[0130] In an exemplary embodiment, the present invention discloses a user
15 equipment (UE) communicatively coupled with a network in a geographical region. The coupling comprises steps of receiving, by the network, a connection request sending an acknowledgment of the connection request to the UE and transmitting a plurality of signals in response to the connection request. The network comprising a plurality of network elements configured to receive a sample data related to one
20 or more parameters associated with the UE, receive a threshold value related to each parameter of the one or more parameters, obtain a weightage value associated with each parameter, calculate a score for each of the UE using the one or more parameters based on a processing of the sample data, the threshold value, and the weightage value corresponding to each parameter and evaluate performance of the
25 UE based on the calculated score.
[0131] Thus, the present invention discloses first identifying the best
category of user device amongst all category of user devices in a grid served by a same cell for a particular KPI. Score the best category as 1 for that KPI in that grid. Compare the other category of user devices with it and if any user device is beyond
30 the pre-defined threshold of that KPI then tag the score to that category of user device for that grid as 0. The other category of user devices falling between the
27

pre-defined threshold and the best in that grid are mapped with score in steps between 1 to 0 as per the descending value of the KPI. Similarly, all KPIs in the grid are checked. Thus, the score for each KPI for each category of the user devices reported in that grid and served by same cell are determined. Thus, the individual 5 score of all categories of the user devices that are reported in that grid are derived. Thus, a score for all category of user devices in the network for every grid where they reported is derived. Further, the score of each category of user device for whole geography is derived and all these category of user devices are compared based on its final score. The best to worst user device can be tagged based on the score which
10 is nothing but the radio frequency (RF) performance.
