The following complete specification particularly describes the disclosure and the manner in which it is performed.

TECHNICAL FIELD

[0001] The embodiments of the present disclosure generally relate to the field of communication networks and systems. More particularly, the present disclosure relates to a system and a method for managing performance of Frequency Division Duplex (FDD) cells by adjusting an antenna tilt on corresponding Time Division Duplex (TDD) cells in the communication network.

BACKGROUND OF THE INVENTION

[0002] The subject matter disclosed in the background section should not be assumed or construed to be prior art merely because of its mention in the background section. Similarly, any problem statement mentioned in the background section or its association with the subject matter of the background section should not be assumed or construed to have been previously recognized in the prior art.

[0003] With increase in technological advancements in the field of telecommunications, several wireless technologies have been developed to meet growing demands of broadband subscribers. During development phase, 3G standards introduced a concept of Time Division Duplexing (TDD) cells in wireless networks, while also establishing a concept of Frequency Division Duplexing (FDD) cells. The TDD cells allow transmission and reception of signals to occur at different times on same frequency, whereas the FDD cells enable a simultaneous transmission and reception of the signals on different frequencies.

[0004] Due to an ability of the FDD cells to handle the simultaneous transmission and the reception of the signals without interference, the FDD cells play a vital role in maintaining network stability and ensuring seamless connectivity, thereby making performance of the FDD cells crucial for optimizing an overall performance of the network.

[0005] However, coexistence of the TDD and the FDD cells posed significant challenges, particularly owing to difficulty in interference management and performance optimization. Heretofore, in conventional communication networks, during interference, an electronic-tilt (e-tilt) executed on the TDD cells led to increased traffic on the corresponding FDD cells. This increased traffic further compromised the performance of the FDD cells, particularly when the FDD cells are already experiencing high utilization or are approaching the capacity of the FDD cells.

[0006] To mitigate the aforementioned issues, existing solutions often rely on default down-tilting mechanisms, which failed to adequately address complex interactions between the TDD and the FDD cells and severity of interference scenarios. Therefore, there lies a need for an improved mechanism that can adapt dynamically to changing network conditions and can address the aforementioned shortcomings of existing solutions related to the interference management.

SUMMARY

[0007] The following embodiments present a simplified summary in order to provide a basic understanding of some aspects of the disclosed invention. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0008] According to an embodiment, a method for managing tilt of an antenna associated with a Time Division Duplex (TDD) cell in a communication network is described. The method includes receiving, by a data exchange engine, first data from the TDD cell and second data from one or more Frequency Division Duplex (FDD) cells associated with the TDD cell. The first data comprises an initial interference value for the TDD cell and an antenna model for the TDD cell, and the second data comprises an operational load value for each of the one or more FDD cells. The method further includes determining, by an antenna inspection engine based on the first data by an antenna inspection engine, whether the antenna model is enabled for a relaxed down tilting configuration. Furthermore, the method includes comparing, by a FDD utilization detection engine, the operational load value for the one or more FDD cells with a predefined load threshold value in response to a determination that the antenna model is enabled for the relaxed down tilting configuration. Furthermore, the method includes comparing, by an interference analysis engine the initial interference value of the TDD cell with a predefined interference threshold in response to a determination that the operational load value of the one or more FDD cells is lower than the predefined load threshold value. Furthermore, the method includes determining, by the interference analysis engine, an interference severity level for the TDD cell from a plurality of interference severity levels based on the comparison of the initial interference value of the TDD cell with the predefined interference threshold value. Furthermore, the method includes altering, by an antenna adjustment engine, the tilting of the antenna to the relaxed down tilting configuration in response to a determination that the interference severity level is low amongst the plurality of interference severity levels.

[0009] In some aspects of the present disclosure, each of the plurality of interference severity levels indicates a range of interference values for the TDD cell.

[0010] In some aspects of the present disclosure, the method further includes receiving, by the interference analysis engine in response to the alteration of the tilting of the antenna to the relaxed down tilting configuration, an updated interference value from the TDD cell. Moreover, the method includes retaining, by the antenna adjustment engine in response to a determination that the updated interference value is lower than an initial interference value, the tilting of the antenna to the relaxed down tilting configuration. Furthermore, the method includes altering, by the antenna adjustment engine in response to a determination that the updated interference value is higher than the initial interference value, the tilting of the antenna to a default down tilting configuration.

[0011] In some aspects of the present disclosure, the method further includes altering, by the antenna adjustment engine, the tilting of the antenna to the default down tilting configuration in response to a determination that the antenna model is disabled for the relaxed down tilting configuration.

[0012] In some aspects of the present disclosure, the method further includes altering, by the antenna adjustment engine, the tilting of the antenna to the default down tilting configuration in response to a determination that the operational load value of the FDD cell is higher than the predefined load threshold value.

[0013] In some aspects of the present disclosure, the method further includes altering, by the antenna adjustment engine, the tilting of the antenna to the default down tilting configuration in response to a determination that the interference severity level is high amongst the plurality of interference severity levels.

[0014] According to another embodiment, a system to manage tilting of an antenna in a communication network is provided. The system includes a data exchange engine, an antenna inspection engine, a Frequency Division Duplexing (FDD) utilization detection engine, an interference analysis engine, and an antenna adjustment engine communicatively coupled to one another. The data exchange engine is configured to receive first data from the TDD cell and second data from one or more Frequency Division Duplex (FDD) cells associated with the TDD cell. The first data comprises an initial interference value for the TDD cell and an antenna model for the TDD cell, and the second data comprises an operational load value for each of the one or more FDD cell. The antenna inspection engine is configured to determine whether the antenna model is enabled for a relaxed down tilting configuration, based on the first data. The FDD utilization detection engine is configured to compare the operational load value for the one or more FDD cells with a predefined load threshold in response to a determination that the antenna model is enabled for the relaxed down tilting configuration. The interference analysis engine is configured to compare the initial interference value of the TDD cell with a predefined interference threshold value in response to a determination that the operational load value of the one or more FDD cells is lower than the predefined load threshold value. The interference analysis engine is further configured to determine an interference severity level for the TDD cell from a plurality of interference severity levels, based on the comparison of the initial interference value of the TDD cell with the predefined interference threshold value. The antenna adjustment engine is configured to alter the tilting of the antenna to the relaxed down tilting configuration in response to a determination that the interference severity level is low amongst the plurality of interference severity levels.

[0029] Various aspects of the present disclosure provide a system and a method for managing tilt of antenna(e) associated with the Time Division Duplex (TDD) cell(s) in the communication network, thereby managing operational load of the communication network. Particularly, the present disclosure relates to managing operational load on the communication cells in the communication network. In some aspects of the present disclosure, the system and the method provide operations for optimizing performance of Frequency Division Duplex (FDD) cells by selecting an antenna tilt on corresponding Time Division Duplex (TDD) cells in a communication network, thereby improving the performance of the FDD cells corresponding to the interfered TDD cells.

[0030] FIG. 1 illustrates a block diagram depicting a system 100 to manage tilting of an antenna 111 in a communication network, in accordance with an exemplary embodiment of the present disclosure. The embodiments of the system 100 shown in FIG. 1 are for illustration only. Other embodiments of the system 100 may be used without departing from the scope of this disclosure.

[0031] The system 100 includes a communication cell cluster 101 comprising multiple communication cells 102 (i.e., presented by way of first through third communication cells 102a-102c) and a data processing server 104 communicatively coupled to each other by way of a network 106. The clustered architecture of the communication cell cluster 101 allows for scalable and distributed deployment of the communication cells 102 to cover large geographical areas and support a high volume of network traffic.

[0032] Each communication cell 102 may include structural and functional components, that when operated in cumulation may be configured to collectively provide wireless communication service(s). For example, each communication cell 102 may be equipped with transmitters, receivers, antennas, and data processors for transmitting and receiving data and/or signals. Each communication cell 102 operates within specified frequency bands to provide wireless communication for a variety of user devices such as portable user devices (e.g., mobile phones, tablet PCs, smart watches, automobile communication systems etc.) and/or fixed electronic devices (e.g., smart television, fixed routers, data centers, etc.).
[0033] Although, in the presented aspect of the present disclosure, FIG. 1 illustrates the communication cell cluster 101 having three communication cells (i.e., the first through third communication cells 102a-102c), it will be apparent to a person of ordinary skill in the art that the scope of the present disclosure is not limited to it. In various other aspects, the communication cell cluster 101 may include any number of communication cells 102, without deviating from the scope of the present disclosure. In such a scenario, each communication cell 102 may be structurally and functionally similar to the first through third communication cells 102a-102c as disclosed herein.

[0034] Particularly, each communication cell 102 may have Frequency Division Duplex (FDD) cell(s) 108 (i.e., presented by way of first through third FDD cells 108a-108c for the first through third communication cells 102a-102c, respectively) and Time Division Duplex (TDD) cell(s) 110 (i.e., presented by way of first through third TDD cells 108a-108c for the first through third communication cells 102a-102c, respectively). The TDD cell(s) 108 may generate TDD aggregator(s) that associate the FDD cell(s) 110 with the TDD cell(s) 108. Each FDD cell 108 uses separate frequency bands for uplink and downlink communication. Each TDD cell 110 uses the same frequency band for uplink and downlink but only communicates in one direction at a time instance. Preferably, each communication cell 102 may have a FDD-TDD cell pair. For example, the first communication cell 102a may have the first FDD cell 108a and the first TDD cell 110a, the second communication cell 102b may have the second FDD cell 108b and the second TDD cell 110b, and so on) such that each communication cell 102 is enabled with both FDD and TDD communication capabilities to cater a variety of communication services.

[0035] Each communication cell 102 may further be equipped with an antenna 111 (i.e., presented by way of first through third antennae 111a-111c for the first through third communication cells 102a-102c, respectively), that can enable transmission and/or reception of communication signal(s) for the communication cell 102 through wireless communication signals.

[0036] An angle of the antenna 111 may have an impact on radiation
(e.g., radiation of electromagnetic waves) by the antenna 111 that may impact various communication parameters (such as interference, coverage area, resource utilization, operational load, etc.) of the communication cell 102. Specifically, an interference between the TDD cell 110 of the communication cell 102 and the associated FDD cell(s) 108 may be altered by changing the angle of the antenna 111.

[0037] Each FDD cell 108 may include logic, circuitry, and/or code(s) that enable transmission and reception of communication signals using separate frequency bands for transmission and reception. Each TDD cell 110 may include logic, circuitry, and/or code(s) that enable transmission and reception of independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern. In some aspects of the present disclosure, each TDD cell 110 is maintained to communicate at a frequency band of 2300 MHz and the associated FDD cell(s) 108 are maintained to communicate at frequency bands of 850 MHz and 1800 MHz. Specifically, the antenna 111 of the TDD cell 110 may be designed to generate communication signals for 2300 MHz frequency band, whereas the antenna 111 of the FDD cell 108 may be designed as dual band antenna and may generate communication signals for 850 MHz frequency band as well as 1800 MHz frequency band.

[0041] The communication interface 116 may be configured to enable the data processing server 104 to communicate with various entities (or operational components) of the system 100 via the network 106. Examples of the communication interface 116 may include, but are not limited to, a modem, a network interface such as an Ethernet card, a communication port, and/or a Personal Computer Memory Card International Association (PCMCIA) slot and card, an antenna, a radio frequency (RF) transceiver, amplifier(s), a tuner, oscillator(s), a digital signal processor, a coder-decoder (CODEC) chipset, a subscriber identity module (SIM) card, and a local buffer circuit. It will be apparent to a person of ordinary skill in the art that the communication interface 116 may include any device and/or apparatus capable of providing wireless or wired communications between the data processing server 104 and various other entities of the system 100.

[0042] The network 106 may include suitable logic, circuitry, and interfaces that may be configured to provide several network ports and several communication channels for transmission and reception of data related to operations of various entities of the system 100. Each network port may correspond to a virtual address (or a physical machine address) for transmission and reception of the communication data. For example, the virtual address may be an Internet Protocol Version 4 (IPV4) (or an IPV6 address) and the physical address may be a Media Access Control (MAC) address.

Aspects of the present disclosure are intended to include or otherwise cover any type of communication channel, including known, related art, and/or later developed technologies.

[0043] In some aspects of the present disclosure, the system 100 may further include the user device 107 that may enable a user to provide input(s) to the data processing server 104. The user device 107 may further present (or display) enable the user to view or display output(s) generated by the data processing server 104. More specifically, the output(s) may be associated with operation(s) performed by the system 100 for selection of tilting of the antennas 111 associated with the communication cells 102. In some aspects of the present disclosure, the user device 107 may further include a console (not shown) to run a computer-executable software application that may be stored in an internal memory (not shown) of the user device 107 and may enable the user to provide instruction(s) and retrieve result(s) from the data processing server 104. In some aspects of the present disclosure, the console may include suitable logic, instructions, and/or codes for executing various operations and may be controlled by the data processing server 104.

[0044] In operation, the data processing server 104 may further receive first data from identified TDD cell 110 (hereinafter interchangeably referred to and designated as ‘the TDD cell 110’) and second data from the Frequency Division Duplex (FDD) cell(s) 108 associated with the TDD cell 110. The first data comprises an initial interference value for the TDD cell 110 and an antenna model for the TDD cell 110. The initial interference value indicates a value of interference observed by the TDD cell 110 when the antenna 111 is tilted at a default down tilting configuration. The second data comprises information of an operational load value for the FDD cell(s) 108. Based on the received first and second data, the data processing server 104 may identify TDD cell(s) 110 associated with unusual (or abnormal) interference values. The data processing server 104 further determines whether the antenna model is enabled for a relaxed down tilting configuration, based on the first data. Furthermore, the data processing server 104 compares, in response to a determination that the antenna model is enabled for the relaxed down tilting configuration, the operational load value for the FDD cell(s) 108 with a predefined load threshold value. The predefined load threshold value may indicate a value of operational load, beyond which the FDD cell(s) 108 may malfunction/fail to provide an optimal throughput. Furthermore, the data processing server 104 compares, in response to a determination that the operational load value of the FDD cell(s) 108 is lower than the predefined load threshold value, the initial interference value of the TDD cell 110 with a predefined interference threshold value. Furthermore, the data processing server 104 determines an interference severity level for the TDD cell 110 from multiple interference severity levels based on the comparison of the initial interference value of the TDD cell 110 with the predefined interference threshold value. Each interference severity levels indicates a range of interference values for the TDD cell 110. Furthermore, the data processing server 104 alters, in response to a determination that the interference severity level is low amongst the interference severity levels, the tilting of the antenna 111 to the relaxed down tilting configuration. Upon altering the tilting of the antenna 111, the data processing server 104 receives an updated interference value from the TDD cell 110. The updated interference value may be identified based on the alteration of the tilting of the antenna 111 to the relaxed down tilting configuration. The data processing server 104 further compares the updated interference value with the initial interference value. Furthermore, the data processing server 104 retains, in response to a determination that the updated interference value is lower than the initial interference value, the tilting of the antenna 111 to the relaxed down tilting configuration. Moreover, the data processing server 104 alters, in response to a determination that the updated interference value is higher than the initial interference value, the tilting of the antenna 111 to a default down tilting configuration.

[0045] Moreover, the data processing server 104 alters the tilt of the antenna to the default down tilting configuration, in response to a determination that the antenna model is disabled for the relaxed down tilting configuration. Moreover, the data processing server 104 alters the tilt of the antenna to the default down tilting configuration, in response to a determination that the operational load value of the FDD cell is higher than the predefined load threshold value. Moreover, the data processing server 104 alters the tilt of the antenna to the default down tilting configuration, in response to a determination that the interference severity level is high amongst the interference severity levels.

[0046] Although FIG. 1 illustrates one example of the system 100, various changes may be made to FIG. 1. Further, the system 100 may include any number of components in addition to the components shown in FIG. 1. Further, various components in FIG. 1 may be combined, further subdivided, or omitted and additional components may be added according to particular needs. The data processing server 104 may retrieve communication data from the communication cells 102 periodically, continuously, or on instance basis.

[0047] FIG. 2 illustrates a block diagram depicting the data processing server 104, in accordance with an exemplary embodiment of the present disclosure. The data processing server 104 may include the data processing circuitry 112, the server memory 114, the communication interface 116, an Input-Output (I/O) interface 201, and a console host 202 coupled to each other via a first communication bus 203.

[0048] The I/O interface 201 may include suitable logic, circuitry, interfaces, and/or codes that may be configured to receive input(s) and present (or display) output(s) on the data processing server 104.

In some aspects of the present disclosure, the console host 202 may include suitable logic, instructions, and/or codes for executing various operations of one or more computer executable applications to host the console on the user device 107, by way of which a user can trigger the data processing server 104 to alter the tilt of the antenna(e) 111. In some other aspects of the present disclosure, the console host 202 may provide a Graphical User Interface (GUI) for the data processing server 104 for user interaction.

[0050] The data processing circuitry 112 may include data processor(s) (e.g., data processing engines) as presented in FIG. 2. According to an exemplary embodiment, the data processing circuitry 112 may include a data exchange engine 204, an antenna inspection engine 206, a FDD utilization detection engine 208, an interference analysis engine 210, an antenna adjustment engine 212, and a communication management engine 214 coupled to each other by way of a second communication bus 226.

[0051] The data exchange engine 204 may be configured to enable transfer of data from the server memory 114 to various engines of the data processing circuitry 112. The data exchange engine 204 may further be configured to enable a transfer of the first data and the second data from the communication cells 102 to the data processing server 104. The first data comprises an initial interference value for the TDD cell 110 and an antenna model for the TDD cell 110. The second data comprises information of an operational load value for the FDD cell(s) 108. In some aspects of the present disclosure, the communication cells 102 may be configured to transmit the first data and/or the second data to the data processing server 104 periodically (e.g., daily, twice a day, hourly, based on a configuration of the communication cells 102) or based on a user intervention (e.g., based on a user’s request for sharing the first data and/or the second data with the data processing server 104).

[0052] Based on the received first and second data, the data exchange engine 204 may identify TDD cell(s) 110 associated with unusual (or abnormal) interference values. In some aspects of the present disclosure, abnormality can be determined by the data exchange engine 204 based on performance parameter(s) of the TDD cell(s) 110 such as coverage area, power consumption, power dissipation, operational load, etc. In an aspect of the present disclosure, the data exchange engine 204 may identify the abnormal TDD cell(s) 110 that require alteration in their antenna angle, which may alter the performance parameters of the associated communication cell 102.

[0053] The data exchange engine 204 may be configured to enable transfer of the data and/or instructions between various other engines of the data processing circuitry 112. Specifically, the data exchange engine 204 may be configured to share the first data of the TDD cell 110 (i.e., the identified abnormal TDD cell 110) and the FDD cell(s) 108 associated to the TDD cell 110 to the antenna inspection engine 206 for further operation(s).

[0054] The antenna inspection engine 206 may receive the first data for the TDD cell 110 and the second data for the FDD cell(s) 108 associated with the TDD cell 110 from the data exchange engine 204. The antenna inspection engine 206 may further determine whether the antenna model is enabled for the relaxed down tilting configuration, based on the first data of the TDD cell 110. In some aspects of the present disclosure, the antenna inspection engine 206 may retrieve technical specifications of the antenna 111 such as, but not limited to, frequency range, angular range of operation, radiation profile, radiation loss profile, and the like. Based on the technical specifications, the antenna inspection engine 206 may determine whether the antenna model (i.e., associated with an antenna 111 corresponding to the TDD cell 110) is enabled for the relaxed down tilting configuration.

[0055] In a scenario, when the antenna inspection engine 206 determines that the antenna model is disabled (or not supported) for the relaxed down tilting, the antenna inspection engine 206 may generate and send a specification denial signal to the antenna adjustment engine 212. In response to the specification denial signal, the antenna adjustment engine 212 may generate a default down tilting signal to enable the antenna 111 to be configured to the default down tilting configuration.

[0056] In another scenario, when the antenna inspection engine 206 determines that the antenna model is enabled for the relaxed down tilting configuration, the antenna inspection engine 206 may transmit the first data and the second data to the FDD utilization detection engine 208 for further processing.

[0057] The FDD utilization detection engine 208 may retrieve the operational load on the FDD cell(s) 108 from the second data. The FDD utilization detection engine 208 may compare the operational load value for the FDD cell(s) 108 with the predefined load threshold value to determine whether the operational load value for the FDD cell(s) 108 is higher or lower than the predefined load threshold value.

[0058] In a scenario, when the operational load value for the FDD cell(s) 108 associated with the TDD cell 110 is higher than the predefined load threshold value, the FDD utilization detection engine 208 may generate and transmit an overload signal to the antenna adjustment engine 212. The overload signal enables the antenna adjustment engine 212 to generate the default down tilting signal to enable the antenna 111 to be configured to the default down tilting configuration.

[0059] In another scenario, when the operational load value for the FDD cell(s) 108 is lower than the predefined load threshold value, the FDD utilization detection engine 208 may transmit the first data and the second data to the interference analysis engine 210 for further processing.

[0060] Upon receiving the first and second data from the FDD utilization detection engine 208, the interference analysis engine 210 may be configured to determine the initial interference value of the TDD cell 110. The interference analysis engine 210 may further determine the interference severity level for the TDD cell 110 from multiple interference severity levels based on the comparison of the initial interference value of the TDD cell 110 with the predefined interference threshold value. In some aspects of the present disclosure, the interference severity levels can be ‘low’, ‘middle’, or ‘high’. Each interference severity level can be associated with a range of interference values associated with the initial interference value of the TDD cell 110. Each interference severity levels indicates a range of interference values for the TDD cell 110.

[0061] In a scenario, when the interference severity level is ‘high’ amongst the multiple interference severity levels, the interference analysis engine 210 may generate and send a high severity signal to the antenna adjustment engine 212. The high severity signal enables the antenna adjustment engine 212 to generate the default down tilting signal to enable the antenna 111 to be configured to the default down tilting configuration.

[0062] In another scenario, when the interference severity level is ‘low’ amongst the multiple interference severity levels, the interference analysis engine 210 may generate and transmit a low severity signal to the antenna adjustment engine 212. The low severity signal enables the antenna adjustment engine 212 to generate a relaxed down tilting signal to enable the antenna 111 to be configured to the relaxed down tilting configuration. Upon altering the tilt of the antenna 111 to the relaxed down tilting configuration, the interference analysis engine 210 receives the updated interference value from the TDD cell 110. The interference analysis engine 210 further compares the updated interference value with the initial interference value.

[0063] In a scenario, when the updated interference value from the TDD cell 110 is lower than the initial interference value, the antenna adjustment engine 212 may generate a retain signal for the antenna adjustment engine 212 that enables the antenna 111 to retain the relaxed down tilting configuration.

[0064] In another scenario, when the updated interference value from the TDD cell 110 is higher than or equal to the initial interference value, the antenna adjustment engine 212 may generate the default down tilting signal to enable the antenna 111 to be configured to the default down tilting configuration.

[0065] The communication management engine 214 may be configured to manage communication frequency bands for transmission and/or reception by the TDD cell 110 and the associated FDD cell(s) 108. In some aspects of the present disclosure, the TDD cell 110 is maintained to communicate at the frequency band of 2300 MHz and the associated FDD cell(s) 108 are maintained to communicate at the frequency of 850 MHz and 1800 MHz. Preferably, the FDD cell(s) 108 are configured to transmit at 850 MHz and receive at 1800 MHZ, or vice-versa.

[0066] In some aspects of the present disclosure, the data exchange engine 204, the interference analysis engine 210, and the antenna adjustment engine 212 co-operatively operate to determine the relaxed down tilting configuration of the antenna 111. Specifically, the relaxed down tilting configuration is determined by iteratively updating the tilt of the antenna 111 to change the interference severity level from ‘the high interference severity level’ to ‘the low interference severity level’. In some aspects of the present disclosure, each antenna 111 may be associated with a tilting mechanism (not shown) configured to adjust the tilting configuration of the antenna to preset tilting configurations (i.e., the relaxed down tilting or the default down tilting) based on the signal(s) received from the antenna adjustment engine 212. The default down tilting configuration of the antenna 111 may be a predefined tilting configuration derived while testing a communication spectrum of the antenna 111 for optimal transmission of the antenna 111 in idle environmental conditions. The relaxed down tilting configuration of the antenna 111 may a suitable tilting configuration for the antenna 111 derived while testing the communication spectrum of the antenna in high interference conditions.

[0067] Various engines of the data processing circuitry 112 are presented to illustrate the functionality driven by the data processing server 104. It will be apparent to a person having ordinary skill in the art that various engines in the data processing circuitry 112 are for illustrative purposes and not limited to any specific combination of hardware circuitry and/or software.

[0068] The server memory 114 may be configured to store data corresponding to the system 100. In some aspects of the present disclosure, the server memory 114 may be segregated into multiple repositories that may be configured to store a specific type of data. In the exemplary embodiment as presented through FIG. 2, the server memory 114 includes instructions repository 216, FDD data repository 218, TDD data repository 220, and antenna data repository 222.

[0069] The instructions repository 216 is configured to store instructions and/or codes for operation(s) of various components of the data processing server 104. FDD data repository 218 is configured to store specification details (such the first data) for each FDD cell of the FDD cell(s) 108. TDD data repository 220 is configured to store specification details (such as the second data) for each TDD cell of the TDD cell(s) 110. Antenna data repository 222 may be configured to store specification(s) (such as tilt angle, antenna model, antenna specifications) associated with the antenna 111. The antenna model may indicate a type of the antenna 111. For example, the antenna model may indicate the antenna 111 is which one from an aperture antenna, log-periodic antenna, microstrip antenna, travelling-wave antenna, etc. The antenna model may also indicate a type of down tilting configuration supported by the antenna 111.

[0070] According to an embodiment of the present disclosure, the instructions repository the instructions repository 216 may be configured to store computer program instructions corresponding to the operation(s) performed by various engines in the processor(s) 112. In an embodiment of the present disclosure, the instructions repository 216 may be configured as a non-transitory storage medium. Examples of the instructions repository 216 configured as the non-transitory storage medium includes hard drives, solid-state drives, flash drives, Compact Disk (CD), Digital Video Disk (DVD), and the like. Aspects of the present disclosure are intended to include or otherwise cover any type of non-transitory storage medium as the instructions repository 216, without deviating from the scope of the present disclosure. As will be appreciated, any such computer program instructions stored in the instructions repository 216 may be executed by one or more computer processors, including without limitation a general-purpose computer or special purpose computer, or other programmable processing apparatus to produce a machine, such that the computer program instructions which execute on the computer processor(s) or other programmable processing apparatus create means for implementing the function(s) specified.

[0071] It will be apparent to a person of ordinary skill in the art that the repositories in the server memory 114 are presented based on the functionality of the data processing server 104 and are not limited to those disclosed. The server memory 114 may have any configuration, combination and/or count of repositories without deviating from the scope of the present disclosure. Although FIG. 2 illustrates one example of the data processing server 104, various changes may be made to FIG. 2. Further, the data processing server 104 may include any number of components in addition to those shown in FIG. 2, without deviating from the scope of the present disclosure. Further, various components in FIG. 2 may be combined, further subdivided, or omitted and additional components may be added according to particular needs.

[0072] FIG. 3 presents a flow chart that depicts a method 300 for managing the tilt of the antenna 111 in the communication network, in accordance with an exemplary embodiment of the present disclosure.

[0073] At block 302, the data processing server 104 may receive the first data from the TDD cell 110 and the second data the FDD cell(s) 108 associated with the TDD cell 110. The data processing server 104 may determine the antenna specification from the first data for the TDD cell 110.

[0074] At block 304, the data processing server 104 may determine whether the antenna model is enabled for the relaxed down tilting configuration, based on the first data of the TDD cell 110. In some aspects of the present disclosure, the data processing server 104 may compare the antenna specification with a predefined antenna specification. Based on the comparison, the data processing server 104 may determine whether the antenna 111 is enabled for (or supports) the relaxed down tilting configuration. When the data processing server 104 determines that the antenna 111 is not enabled (or disabled) for the relaxed down tilting configuration, the method 300 proceeds to block 306. Else, when the data processing server 104 determines that the antenna 111 is enabled for the relaxed down tilting configuration, the method proceeds to step 308.

[0075] At step 306, the data processing server 104 may select the default down tilting configuration for the antenna 111.

[0076] At block 308, the data processing server 104 may retrieve the operational load value for the FDD cell(s) 108 from the second data to determine the utilization of the FDD cell(s) 108 corresponding to the TDD cell 110.

[0077] At block 310, when the operational load value for the FDD cell(s) 108 is higher than the predefined load threshold value (i.e., when the FDD cell(s) 108 are highly utilized), the method proceeds to block 312. Else, when the operational load value is lower than the predefined load threshold value (i.e., the FDD cell(s) 108 are underutilized), the method 300 proceeds to block 314.

[0078] At block 312, the data processing server 104 may select the default down tilting configuration for the antenna 111, and the method 300 halts.

[0079] At block 314, the data processing server 104 may determine the initial interference value for the TDD cell 110 from the first data.

[0080] At block 316, the data processing server 104 may compare the initial interference value with the predefined interference value. Based on the comparison, the data processing server 104 may determine the interference severity level for the TDD cell 110. In some aspects of the present disclosure, when the initial interference value is higher than the predefined interference threshold value, the data processing server 104 may identify ‘high interference severity level’, else the data processing server 104 may identify ‘low interference severity level’ for the TDD cell 110.

[0081] When the ‘high interference severity level’ is identified, the method 300 proceeds to block 318. Else when the ‘low interference severity level’ is identified, the method 300 proceeds to block 320.
[0082] At block 318, the data processing server 104 may select the default down tilting configuration for the antenna 111, and the method 300 halts.

[0083] At block 320, the data processing server 104 may alter the tilt of the antenna 111 to the relaxed down tilting configuration.

[0084] At block 322, the data processing server 104 may determine the updated interference value for the TDD cell 110. In some aspects of the present disclosure, upon alteration of the tilt of the antenna 111 to the relaxed down tilting configuration, the data processing server 104 may receive an updated first data from the TDD cell 110, based on which the updated interference value is retrieved.

[0085] At block 324, the data processing server 104 may compare the updated interference value with the initial interference value. Based on the comparison, when the interference value is reduced (i.e., the updated interference value is lower than the initial interference value), the method 300 proceeds to block 328. Else, when the updated interference value is not lower than the initial interference value, the method 300 proceeds to block 326.

[0086] At block 326, the data processing server 104 may alter the tilt of the antenna 111 to the default down tilting configuration, and the method 300 halts.

[0087] At block 328, the data processing server 104 may retain the tilt of the antenna 111 to the relaxed down tilting configuration.

[0088] Now, referring to the technical abilities and advantageous effect of the present disclosure, operational advantages that may be provided by one or more embodiments may include providing the system 100 and the method 300, capable of identifying antenna(e) 111 associated with the TDD cell(s) 110 causing the interference and adjusting the down tilt of the corresponding antenna(e) 111 based on the interactions between the TDD cell(s) 110 and the FDD cell(s) 108, and the severity of interference on the FDD cell(s) 108 in the communication scenarios. This analytic adjustment of the antenna(e) 111 helps in minimizing the interference on the associated FDD cell(s) 108 and thereby enhancing communication capabilities of the network 106. Moreover, the system 100 supports in regulation and management of dynamically increasing traffic in the communication networks by optimizing the efficiency of channel occupancy in the communication networks by conditionally switching between the FDD cell(s) 108 and the TDD cell(s) 110 (i.e., switching the frequency channels for receiving different frequency signals) to reduce interference and achieve higher Quality of Service.
