     This application claims the benefit of Indian Application No. 202111000546 titled “Method and Apparatus for Remote Sensing of Antenna Configuration Parameters” filed by the applicant on 6th Jan. 2021, which is incorporated herein by reference in its entirety. 
     FIELD OF THE INVENTION 
     Embodiments of the present invention relate to the field sensing technology. And more particularly, relates to a method and apparatus for remote sensing of antenna configuration parameters. 
     DESCRIPTION OF THE RELATED ART 
     Of late, an accurate site physical location and installation information such as, but not limited to, latitude, longitude, height, mechanical tilt, azimuth of an antenna system has been a challenge for operators. While accuracy of such information is very useful for the operators to make key planning decisions of a network on operating expenses (Opex) and capital expenditures (Capex), the process of finding such information is manual and physical site surveys are required to gather such information. 
     The operators are spending millions of dollars in the information gathering projects to get the accurate data and still there is no surety whether the data collected is relevant, as it needs human intervention to get parameters captured that are prone to error. 
     In current scenario, every operator follows set up activities for conducting the physical surveys such as manual site survey using external global positioning system (GPS), tilt meters, height laser meters and compass; external sensor module on passive antenna system with proprietary interfaces to capture data or the like. 
     Although there have been several advancements made to create an integrated module to capture all the information of the antenna system, since an antenna is a passive element, putting an active sensor on the antenna makes it a non-feasible and non-viable solution. 
     A Chinese Patent Application “CN201629398U” discloses an integrated antenna with a remote radio frequency unit (RRU), which comprises the remote radio frequency unit (RRU) and an antenna part arranged on and tightly combined with the remote radio frequency unit, wherein the antenna part comprises an antenna base plate arranged on the remote radio frequency unit (RRU), an upper cover matched with the base plate, a reflecting plate arranged between the base plate and the upper cover, a vibrator arranged on the reflecting plate and a radio frequency connector electrically connected with the vibrator. Particularly, the integrated antenna adopts an integrated design, and the overall appearance of the integrated antenna is that the antenna part is integrated with the remote radio frequency unit (RRU), thus guaranteeing the concealed property and attractive appearance of the integrated antenna; the antenna part and the remote radio frequency unit (RRU) are integrated together, the core wire used for connecting the remote radio frequency unit (RRU) with the antenna can be designed to be short, thus being capable of improving the transmission efficiency. In addition, by the integrated design, the requirement of later network supplement can be met in one network construction, and the antenna can be installed extremely and conveniently without a supporting part for foundation construction. 
     Another WIPO Patent Application “WO2016088126A1” discloses a method for tuning an antenna assembly. The antenna assembly comprises a main reflector, a sub-reflector and a feed, the sub-reflector is provided with a plurality of actuators adapted to locally deform the curvature of the sub-reflector in response to an activation signal, the method comprising deploying a plurality of transmission sensors at a target area of the transmission illumination the antenna assembly, activating transmission from the antenna assembly, measuring and recording level of transmission power at each of the plurality of sensors along with the location of the respective sensor, extracting actual antenna assembly illumination footprint map from the recorded values, comparing the extracted illumination footprint map to a desired footprint, and providing activation signals to at least some of the actuators to deform the curvature of the sub-reflector so that the footprint of the illumination by the antenna assembly at the target area matches the desired footprint. 
     Further, another Chinese Patent Application “CN102820893A” discloses an integrated modularized system including an RRU (remote radio unit) and an antenna, and a mobile communication base station, belonging to the communication technology. The integrated modularized system comprises a main control module for active control; at least one active radiation module connected with the main control module, and a radiator arranged between the main control module and the active radiation module, wherein the active radiation module includes an antenna oscillator, an antenna filter, and a transceiving unit. The antenna filter, the transceiving unit and the antenna oscillator in the RRU can be integrally arranged in the active radiation module by arranging the main control module for active control in the RRU independently, so that the RRU can be completely integrated with the smart antenna, thereby obviating feeder connection between the antenna and the active equipment and further obviating feeder loss. The integrated modularized system provided by the invention is convenient in installation, and is improved in reliability by arranging the antenna, the oscillator, the filter and a power amplifier in the active radiation module.

     Open-Radio Access Network (O-RAN), is an evolved version of prior radio access networks, makes the prior radio access networks more open and smarter than previous generations.   

       FIG. 1A  is a block diagram of an apparatus for remote sensing of a plurality of antenna configuration parameters in accordance with an embodiment of the present invention. In particular, the apparatus ( 100 ) comprises a sensor module ( 102 ) communicating with a plurality of hardware devices ( 106 ) via an interface ( 104 ). Moreover, the sensor module ( 102 ), is placed in a radio unit (RU) (as illustrated in  FIG. 2 a    and  FIG. 2 b   ). Furthermore, the sensor module ( 102 ) is integrated with an antenna system (or antenna). Subsequently, the antenna senses and/or captures the plurality of antenna configuration parameters/data such as, but not limited to, latitude, longitude, height, mechanical tilt, azimuth, location, angle of the antenna or antenna system. Further, the sensor module ( 102 ) transmits captured sensor data, as per antenna alignment (direction and angle of the antenna to its axis), to the plurality of hardware devices ( 106 ) by means of the RU. 
     In general, the RU handles digital front end (DFE) and parts of physical layer (PHY) and digital beamforming functionality. And, the radio unit enables remote sensing of the plurality of antenna configuration parameters. 
     In accordance with an embodiment of the present invention, the plurality of hardware devices ( 106 ) may be vendor independent and operator independent hardware devices ( 106 ). In particular, the plurality of hardware devices ( 106 ) may include at least one of a Remote Management System (RMS), a Network Management System (NMS), an Element Management System (EMS)/operations support system (OSS) and a distributed unit (DU). 
     In accordance with an embodiment of the present invention, the EMS may manage specific types of one or more network elements within a telecommunication management network (TMN). In particular, the EMS within a network element may manage functions and capabilities, and not necessarily traffic. Moreover, the EMS may communicate upward to higher-level systems of network management (NMS), in order to manage the traffic between itself and other network elements. 
     In accordance with an embodiment of the present invention, the RMS is a remote monitoring and management system which may remotely monitor the radio units or networking devices. Particularly, the RMS may monitor, manage and control the remote radio units and networking devices. 
     In accordance with an embodiment of the present invention, the network management system may be an application aimed to analyze, control and manage network and service infrastructure in order to ensure its configuration correctness, robustness, performance quality and security. 
     In accordance with an embodiment of the present invention, the operations support system (OSS) may be a software component that enables a service provider to monitor, control, analyze, and manage the services on its network. Furthermore, the distributed unit may sit close to the RU and may be a logical node that includes a subset of eNB/gNB functions. 
     In a 5G radio access network (RAN) architecture, a baseband unit functionality may split into two functional units, i.e., the DU, responsible for real time L1 and L2 scheduling functions, and a centralized unit (CU) responsible for non-real time, higher L2 and L3. In a 5G cloud RAN, the DU&#39;s server and relevant software may be hosted on a site itself or may be hosted in an edge cloud (data center or central office) depending on transport availability and fronthaul interface. 
     The detailed working of the sensor module ( 102 ), the interface ( 104 ) and the RU is explained in conjunction with  FIG. 1B ,  FIG. 1C ,  FIG. 2A  and  FIG. 2B . 
       FIG. 1B  is a block diagram illustrating elements of a sensor module ( 102 ) of the apparatus in accordance with an embodiment of the present invention. In particular, the sensor module ( 102 ) includes a plurality of sensors to capture the plurality of antenna configuration parameters. Moreover, the plurality of sensors may be, but not limited to, a global positioning system (GPS) module ( 108 ), a compass ( 110 ), an accelerometer ( 112 ), a gyroscope ( 114 ), an inclinometer ( 116 ) and an altimeter ( 118 ). 
     In accordance with an embodiment of the present invention, the GPS module ( 108 ) measures location parameters, the compass ( 110 ) is used for capturing azimuth/orientation parameters, the accelerometer ( 112 ) is used for capturing vibration parameters, the gyroscope ( 114 ) captures yaw measurement, the inclinometer ( 116 ) measures tilt parameters and the altimeter ( 118 ) senses parameters related to height of the antenna system. 
     In accordance with an embodiment of the present invention, the GPS module ( 108 ) obtains location parameters of the antenna system. 
     In an exemplary example, for a site, if there are three antennas placed within 5 m from each other, an approximate location can be taken common for all the three antennas. If any one of the antennas is placed farther than 5 m from the other antennas (for example: one antenna placed on a rooftop) then location for that antenna will be recorded exactly as per the GPS module ( 108 ). 
     Similarly, the azimuth will remain the same when the compass ( 110 ) is placed in the same orientation as the antenna (or antenna system) and the vibration and yaw parameters will remain same as the RU is attached at the back panel of the antenna. 
     In accordance with an embodiment of the present invention, the inclinometer ( 116 ) is based on the principle of acceleration due to gravity measurements and provides an angle through basic mathematical operations. Particularly, the tilt obtained from the inclinometer ( 116 ) is w.r.t. the standard x-axis. And, to determine the correct antenna tilt from the inclinometer ( 116 ), a correction term is introduced which considers an angle between a reference axis and a vertical axis and an angle between the RU and the antenna, if the RU is not attached exactly parallel to the antenna. The correction term will thus ensure that correct antenna angle is obtained at the end. 
     To determine the correct antenna angle, let actual tilt of the antenna be: θ°, the angle between the inclinometer ( 116 ) and the antenna as: δ° and the inclinometer ( 116 ) reading obtained be: α°. Then, the actual tilt (θ°) will be (α°−δ°). 
     Further, the altimeter ( 118 ) provides reading based on the sea level or ground level. The actual height of the antenna or RU can be obtained by subtracting the altimeter reading from a ground level, i.e., Height w.r.t. ground=Altitude of Unit−Altitude of ground 
     In case of a rooftop antenna, the height of the building will also be taken into consideration. This option would be provided to the operator to enter the height of the building over which antenna is mounted. The actual antenna height will be derived according to the antenna height, height of the building, and placement of the RU. After considering the adjustments in a correction term: 
       Height  w.r.t.  ground=Altitude of RU−Altitude of ground+correction term   (1)
 
     Considering height of antenna: x, considering the RU be placed approximately at the centre of the antenna, or considering the altimeter ( 118 ) be present at the centre of the antenna, considering height of altimeter be recorded as: h. Thus, to get a total height, x/2 will be added to height of the altimeter. Thus, the actual height=h+x/2. The x/2 can be replaced by other correction term if the RU is not present at the exact centre of the antenna. 
       FIG. 1C  is a block diagram illustrating elements of an interface of the apparatus in accordance with an embodiment of the present invention. In particular, the interface ( 104 ) is an end point or gateway of the radio unit ( 202 ) that connects with external entities such as RMS/EMS/DU or any other hardware devices. Moreover, the interface ( 104 ) may be reprogrammable by using wired connectivity or over the air (wireless connectivity), thus may also be referred to as a programmable interface. Furthermore, the interface ( 104 ) is configured to map the received plurality of antenna configuration parameters, from the sensor module ( 102 ) to the plurality of hardware devices ( 106 ). Subsequently, the interface ( 104 ) is compliant to an open radio access network (O-RAN) architecture system such as O-RAN FH/1588. 
     In particular, the O-RAN provides real-time analytics that drive embedded machine learning systems and artificial intelligence back end modules to empower network intelligence. Moreover, the O-RAN includes virtualized network elements with open and standardized interfaces. Further, the open interfaces are essential to enable smaller vendors and operators to quickly introduce their own services or enable operators to customize the network to suit their own unique needs. 
     The open interfaces also enable multivendor deployments, more competitive and vibrant supplier ecosystems. Similarly, open source software and hardware reference designs enable faster, more democratic and permission less innovation. Further, the O-RAN introduces a self-driving network by utilizing new learning based technologies to automate operational network functions. These learning based technologies make the O-RAN intelligent. Embedded intelligence, applied at both component and network levels, enables dynamic local radio resource allocation, and optimizes network wide efficiency. In combination with O-RAN&#39;s open interfaces, AI-optimized closed-loop automation is a new era for network operations. 
     In accordance with an embodiment of the present invention, the O-RAN architecture system includes a non-real-time RAN controller, a near-real-time RAN controller, a plurality of components. In particular, the plurality of components is at least one of a disaggregated, reprogrammable and vendor independent. Further, the near real-time RAN controller comprises vendor independent application programming interfaces (APIs). 
     In accordance with an embodiment of the present invention, the interface ( 104 ) may use a Yet Another Next Generation (YANG) module ( 104   a ). The YANG module ( 104   a ) utilizes Yet Another Next Generation data modelling language to model and manage the captured data from the sensor module ( 102 ). In particular, the YANG language is used for definition of data sent over network management protocols such as NETCONF and RESTCONF. NETCONF/YANG may provide a standardized way to programmatically update and modify the configuration of the plurality of hardware devices (or network devices). Further, the YANG module describes configuration changes and the NETCONF may be a protocol that applies changes to a relevant datastore (such as running, saved etc.) upon the plurality of hardware devices. The YANG module ( 104   a ) for hardware management may include a mapping unit ( 120 ) to map to different management information base (MIBs) such as RFC (Request for comments) 3433 that can be used to manage the plurality of hardware devices. A Management Information Base (MIB) may be a hierarchical virtual database of network (or other entity) objects describing a device being monitored by the Network Management System (NMS). The MIB is used by Simple Network Management Protocol (SNMP) and Remote Monitoring 1 (RMON1). Here, the MIB for each hardware device may have mapping with the plurality of antenna configuration parameters (sensor data) using the O-RAN compliant programmable interface. 
     The RFC 3433 protocol, in the O-RAN WG4 M-Plane document, is used for management information base. The captured data is updated in a database or a storage unit ( 122 ) associated with the YANG module ( 104   a ) using the RFC 3433 MIB [“entPhysicalClass”, “entPhysicalEntry” and “entPhysicalTable”]. 
     In accordance with an embodiment of the present invention, the mapping unit ( 120 ) in the (programmable) interface is configured to map the plurality of antenna configuration parameters with a plurality of management information bases corresponding to the plurality of hardware devices ( 106 ), and the storage unit ( 122 ) is configured to store the plurality of antenna configuration parameters in the YANG module ( 104   a ) within the interface. The YANG module ( 104   a ) is a common data model for the sensor module ( 102 ) and the plurality of hardware devices ( 106 ) and may also be referred to as a YANG data module ( 104   a ). 
     In accordance with an embodiment of the present invention, the plurality of hardware devices ( 106 ), for example, the EMS/OS S, which is a part of the NMS retrieves all required data form the YANG module ( 104   a ) using allocated interfaces. Typically, the NMS manages a complete network i.e., it covers all the functions of EMS and manages different types of network elements/technologies of a same operator/vendor. Similarly, the OSS can manage multiple operators/vendors and is needed in addition to vendor specific NMS. Further, the plurality of hardware devices ( 106 ) may also include the NMS/DU (distributed unit). 
     Unlike conventional systems, the present invention provides a way to gather information i.e., the plurality of antenna configuration parameters about the antenna from the RU instead of placing sensors on the antenna itself. On the NMS side, the present solution receives the captured data i.e., the plurality of antenna configuration parameters at certain intervals and allows the operators (or vendors) flexibility in deciding so. The data received from the sensors can be: (a) saved in repository and updated at a certain time interval, e.g. , but not limited to, once every 24 hours, where the timing interval may be configurable by the operators and can range from 15 s to 24 hrs. Once logged into the RU, the captured data can be accessed; (b) the data can also be requested by the operators via polling as per the requirement. Further, the parameters like information periodicity and thresholds can be defined/modified by using some pre-defined group objects under the RFC 3433. For example, “entPhySensorUnitDisplay”, “entPhySensorValueUpdateRate” etc. The RFC 3433 provides more options to operators. The operators will have the flexibility to manipulate the thresholds as per their deployment scenarios. Interfacing of the sensor module ( 102 ) in this framework using the RFC 3433 allows the operators to effectively and easily procure and analyse the sensor data.

In particular, the radio unit ( 202 ) provides remote sensing of the plurality of antenna configuration parameters including one or more sensor data values corresponding to the antenna in a wireless communication system. Particularly, the wireless communication system may consist of various network components connected via wireless networks. The wireless networks may comprise any wireless connectivity technology such as radio links, millimeter wave, etc. The wireless communication system may include one or more controllers connected with radio access networks, which are further connected with a plurality of user equipment. 
     In accordance with an embodiment of the present invention, the wireless communication system may include a radio access network (RAN). In particular, the radio access network (RAN) may be a part of a telecommunications system which may connect individual devices to other parts of a network through radio connections. The RAN may provide a connection of user equipment such as mobile phone or computer with a core network of the telecommunication systems. The RAN may be an essential part of the access layer in the telecommunication systems that utilizes base stations (such as e node B, g node B) for establishing radio connections. The RAN includes the radio unit ( 202 ) that is positioned on the antenna. The RU may be a remote radio unit (RRU). The RRU may be a radio frequency (RF) circuitry of a base station enclosed in a small outdoor module. The RRU may perform all RF functionality like transmit and receive functions, filtering, and amplification. It may contain analog-to-digital or digital-to-analog converters and up/down converters as explained in conjunction with  FIG. 2 b   . The RRU may also provide advanced monitoring and control features that allow operators to optimize performance from a remote, centralized location. The RRU is usually mounted near the antenna to reduce transmission line losses and is connected to the main, digital portion of the base station (BBU) with an optical fiber. 
     In accordance with an embodiment of the present invention, the radio unit ( 202 ) includes the sensor module ( 102 ), the interface ( 104 ), a transmission unit ( 124 ) and a monitoring unit ( 126 ). 
     In accordance with an embodiment of the present invention, the sensor module ( 102 ) comprises the plurality of sensors configured to receive the plurality of antenna configuration parameters and the interface ( 104 ) is configured to map the received plurality of antenna configuration parameters from the sensor module ( 102 ) to the plurality of hardware devices ( 106 ) as explained earlier.

Moreover, the sensor module may include at least one of a NETCONF based sensor monitoring module, an alarm system mapped to a watchdog manager (i.e., watchdog manager mapped alarm system), a sensor measurement interval mapped to a common YANG database, an O-RAN compliant sensor management information base (MIB). 
     Alternatively, the NETCONF based sensor monitoring module, the alarm system mapped to the watchdog manager, the sensor measurement interval mapped to the common YANG database, the O-RAN compliant sensor management information base (MIB) may be included in the interface ( 104 ) instead of the sensor module ( 102 ).

The interface ( 104 ), which is O-RAN compliant, may map the sensor information onto the plurality of hardware devices, corresponding to same or multiple vendors, by mapping the plurality of antenna configuration parameters to the plurality of management information bases of the plurality of hardware devices. 
       FIG. 2B  is a high level block diagram illustrating placement of the sensor module in the radio unit (RU) in accordance with an embodiment of the present invention. Particularly, the RU is a distributed and integrated frequency unit that facilitates wireless communication, user equipment and a network. The user equipment may be but not limited to a mobile phone, WLL phone or the like and the network may be 4G, 5G, LTE, GSM, CDMA, Wireless local loop, WAN or the like.

     In accordance with an embodiment of the present invention, the digitally processed signal from the digital processing unit ( 204 ) is fed to the RF processing unit ( 206 ). In particular, the RF processing unit ( 206 ) comprises various elements such as transceiver, ADC/DAC (analog to digital converter/digital to analog converter), mixer, PA/LNA (power amplifier/low noise amplifier) and ANT (wireless radio networking protocol). Moreover, the RF processing unit ( 206 ) processes the signal from the digital processing unit ( 204 ) and transmits back to the digital processing unit ( 204 ). Specifically, the RF processing unit ( 206 ) may convert and amplify the signal. Further, the RF processing unit ( 206 ) implements a wireless communications protocol stack ANT that enables hardware operating in 2.4 GHz ISM (industrial, scientific and medical) band to communicate by establishing standard rules for co-existence, data representation, signaling, authentication, and error detection. 
     In accordance with an embodiment of the present invention, the sensor module ( 102 ) integrated with the RU ( 202 ) has a matching surface to the antenna. That is, the data captured from the sensor module ( 102 ) in the RU ( 202 ) matches antenna alignment information, thereby providing accurate antenna configuration parameters. The antenna alignment information is required for configuring the antenna. Particularly, the sensor module ( 102 ) captures data via the plurality of sensors as explained in  FIG. 1B  that is further received by the microcontroller ( 208 ). And, the sensor data may be received at regular intervals as per the operator&#39;s requirement. Moreover, the sensor module ( 102 ) is connected to [or interfaced with] the microcontroller ( 208 ) via an SPI (Serial Peripheral Interface) and an I 2 C (Inter-Integrated Circuit). 
     The SPI is a synchronous serial communication interface specification used for short-distance communication and the I2C is a serial communication protocol, where data is transferred bit by bit along a single wire (such as SDA (serial data) line). The GPS module ( 108 ) gives output in standard NMEA (National Marine Electronics Association) string format. It provides output serially on a Tx pin with default 9600 Baud rate. Apart from data pin, it requires VCC (Voltage Common Collector) and GND (Ground).

Furthermore, the gyroscope ( 114 ) may be interfaced with the microcontroller ( 208 ) via the I2C and the inclinometer ( 116 ) may be interfaced with the microcontroller ( 208 ) via the SPI and may contain power supply pins as well. Similarly, the altimeter ( 118 ) is also interfaced with the microcontroller ( 208 ) via the I2C. The altimeter ( 118 ) includes a pin through which a supply voltage is to be provided, the SDA pin/line to obtain output, the SCL pin for clock, and INT1 and INT2 for interrupts, if any. 
     In accordance with an embodiment of the present invention, the timing unit ( 210 ) may generate timing signals to control the functions of all the elements of the RU ( 202 ). The timing signals are transmitted to the digital processing unit ( 204 ), the RF processing unit ( 206 ), the sensor module-microcontroller and the ethernet interface ( 212 ) to control their functions. All the processed data/signal by the RU ( 202 ) is transmitted to the fronthaul gateway via the ethernet interface ( 212 ). 
     Advantageously, the antenna integrated with the RRU does not require the RRU to be active, which is power intensive. Hence, the antenna integrated with the RRU may work in passive mode and save a lot of energy while transmitting the plurality of antenna configuration parameters from remote sites to the plurality of hardware devices. Further, the interface may be reprogrammed based on the user requirements and can transmit the plurality of antenna configuration parameters (i.e., sensor information) from remote sites to RMS/EMS/NMS/hardware devices. If the interface is not programmable and O-RAN compliant, it can transmit information to proprietary hardware devices only. Here, the interface is capable of mapping information to multiple vendor independent hardware devices/RMS. Further, the apparatus operates its functions in real-time by capturing any change in the plurality of antenna configuration parameters in real-time and provides traffic monitoring and optimization at the remote site (antenna site).
