Title: Downtime optimized network upgrade process

Description:
SUMMARY 
     The present disclosure is directed, in part, to identifying one or more candidate maintenance windows of at least one cell site of a telecommunications network, substantially as shown in and/or described in connection with at least one of the figures, and as set forth more completely in the claims. 
     In aspects set forth herein, a user device is connected to a telecommunication network. Typically, vendors and operators perform service impacting work to a cell site when network activity is as low as possible. This usually takes place when the affected area is sleeping. With the continual adoption of technology, even at night, network impact is inevitable. However, here, a service management system receives a maintenance request to upgrade at least one cell site and identifies one or more candidate maintenance windows and one or more confidence indicators which minimizes network performance impact during critical maintenance upgrades. 
     This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used in isolation as an aid in determining the scope of the claimed subject matter.

       FIG.  1    illustrates an example of a network environment  100  suitable for use in implementing embodiments of the present disclosure. The network environment  100  is but one example of a suitable network environment and is not intended to suggest any limitation as to the scope of use or functionality of the disclosure. Neither should the network environment  100  be interpreted as having any dependency or requirement relating to any one or combination of components illustrated. 
     The network environment  100  provides service to one or more user devices  120 ,  130 , and  140 . In some embodiments, the network environment  100  may include a telecom network (e.g., a telecommunication network such as, but not limited to, a wireless telecommunication network), or portion thereof. The network environment  100  may include one or more devices and components, such as base stations, servers, switches, relays, amplifiers, databases, nodes, etc. which are not shown so as to not confuse other aspects of the present disclosure. Those devices and components may provide connectivity in a variety of implementations. In addition the network environment  100  may be utilized in a variety of manners, such as a single network, multiple networks, or as a network of networks, but, ultimately, is shown as simplified as possible to avoid the risk of confusing other aspects of the present disclosure. 
     The telecom network included in the network environment  100  may include or otherwise may be accessible through a cell site (e.g., the cell site  110 ). The cell site may include one or more antennas, base transmitter stations, radios, transmitter/receivers, digital signal processors, control electronics, GPS equipment, power cabinets or power supply, base stations, charging stations, etc. such that the cell site may provide a communication link between one or more user devices (e.g., the user devices such as the user devices  120 ,  130 , and  140 ) and other components, systems, equipment, and/or devices of the network environment  100 . The base station and/or a computing device (e.g., whether local or remote) associated with the base station may manage or otherwise control the operations of components of the cell site. 
     In some embodiments, the cell site may be operable in a non-stand alone (NSA) mode. In the non-stand alone mode the network environment  100  may take the form of, for example, an E-UTRAN New Radio-Dual Connectivity (EN-DC) network. In an EN-DC network, a user device may connect to or otherwise access a 4G, LTE, 5G, or any other suitable network. In the stand alone mode, the telecom network may take the form of a 5G, 6G, or any other suitable network. 
     In some embodiments, the network environment  100  may include one or more nodes communicatively coupled to one or more user devices such that the node(s) may transmit to and receive requests and/or data from the user device(s). The one or more nodes may include a Next Generation Node B (e.g., gNodeB or gNB) or any other suitable node. The one or more nodes may correspond to one or more frequency bands within which the user device(s) may connect to the network environment such as, but not limited to, a telecommunication network or a portion thereof. 
     In some embodiments, the node(s) may be included within the cell site (e.g., the cell site  110 ), external to the cell site, or otherwise communicatively coupled to the cell site. The node(s) may allocate radio frequency, or a portion thereof, to user device(s). 
     In some embodiments, the user device(s) may take the form of a wireless or mobile device capable of communication via the network environment  100 . For example, the user device  120  may take the form of a mobile device capable of communication via a telecom network such as, but not limited to, a wireless telecommunication network. In this regard, the user device(s) may be any computing device that communicates by way of a network, for example, a 4G, LTE, WiMAX, Wi-Fi, 5G, 6G, or any other type of network. 
     In some embodiments, the network environment  100  may connect subscribers (e.g., current subscribers and/or potential subscribers) to a service provider or a plurality of service providers. Alternatively or additionally, the network environment  100  may be associated with a specific telecommunication provider or a plurality of telecommunication providers that provide services (e.g. 5G, 6G, voice, location, data, etc.) to one or more user devices. For example, the user devices  120  and  130  may be subscribers to a telecommunication service provider, in which the devices are registered or subscribed to receive voice and data services (e.g., receive content that may be streamed, downloaded, etc.) over the network environment  100 . The network environment  100  may include any communication network providing voice and/or data service(s), such as, for example, a Wi-Fi network, 4G network (LTE, WiMAX, HSDPA), 5G network, or 6G network. 
     Having described the network environment  100  and components operating therein, it will be understood by those of ordinary skill in the art that the network environment  100  is but one example of a suitable network and is not intended to limit the scope of use or functionality of aspects described herein. Similarly, the network environment  100  should not be interpreted as imputing any dependency and/or any requirements with regard to each component and combination(s) of components illustrated in  FIG.  1   . It will be appreciated by those of ordinary skill in the art that the number, interactions, and physical location of components illustrated in  FIG.  1    are examples, as other methods, hardware, software, components, and devices for establishing one or more communication links between the various components may be utilized in implementations of the present invention. It will be understood to those of ordinary skill in the art that the components may be connected in various manners, hardwired or wireless, and may use intermediary components that have been omitted or not included in  FIG.  1    for simplicity&#39;s sake. As such, the absence of components from  FIG.  1    should not be interpreted as limiting the present invention to exclude additional components and combination(s) of components. Moreover, though components may be represented as singular components or may be represented in a particular quantity in  FIG.  1   , it will be appreciated that some aspects may include a plurality of devices and/or components such that  FIG.  1    should not be considered as limiting the quantity of any device and/or component. 
       FIG.  2    is a diagram of the network environment  200  (e.g., a telecommunication environment such as, but not limited to, a wireless telecommunication environment) according to an example embodiment. In the present embodiment, the network environment  200  includes the cell site  110 , service management system  205 , and user devices  120 ,  130 , and  140 . Although some of the components in the network environment  200  are depicted as single components (e.g., a single service management system, cell site, etc.), in some embodiments, the network environment  200  may include a plurality of such components. The service management system  205  may be included within the cell site  110 , external to the cell site  110 , and/or otherwise communicatively coupled to the cell site  110  directly or indirectly. 
     In some embodiments, the service management system (e.g., the service management system  205 ) may receive a maintenance request to upgrade at least one cell site (e.g., the cell site  110 ). As used herein, the term “maintenance request” may be used to refer to a request to upgrade a cell site. The maintenance request may include at least one maintenance requirement (e.g., at least one of a schedule requirement, footprint requirement, or any other suitable requirement). In some embodiments, the schedule requirement may include one or more timing inputs (e.g., upgrade window, upgrade shutout, priority timing, maximum upgrade timing, etc.). The upgrade window may define the window of time during which a single upgrade or a plurality of upgrades may occur. In this regard, the maintenance requirement may include or otherwise may take the form of an upgrade window, upgrade shutout, priority timing, maximum upgrade time, and/or any other suitable requirement. Alternatively or additionally, the timing input (e.g., upgrade shutout) may identify one or more dates or times when an upgrade is not allowed. In some examples, the timing input (e.g., priority timing) may associate a weight to one or more specific dates and/or specific times. The timing input (e.g., maximum upgrade time) may define the maximum time allowed for an upgrade before a required rollback. 
     The maintenance requirement may include one or more footprint requirements. The footprint requirement may include or otherwise take the form of a RAN (Radio Access Network) input, footprint input, and/or rollback requirement. The RAN input may include a RAT (Radio Access Technology) selection (e.g., 2G, 3G, 4G, 5G, internet of things (IoT), etc.), frequency selection, baseband type, vendor input, and/or any other suitable RAN input. The footprint input may indicate the number of cell sites that may be included in an upgrade. For example, the footprint input may indicate an upgrade area level (e.g., cell site, type allocation code (TAC), market, etc.). The type allocation code may be an identifier that refers to the type of user equipment. In further embodiments, the rollback requirement may identify allowed truck rolls (e.g., the number of site visits that may be allowed to fix issues encountered during an upgrade), a layer availability (e.g., a minimum and/or maximum layer availability), and/or one or more thresholds (e.g., one or more rollback thresholds). Exceeding the number of allowed truck rolls may result in a rollback or may prohibit one or more upgrades from taking place (e.g., a site completed stays completed). In some embodiments, the rollback requirement may be included in the maintenance request (e.g., included in an initial maintenance request). Truck roll(s) may indicate the number of site visits that may be required to recover equipment if there is an issue encountered during the upgrade. In some examples, a market may permit a maximum number of truck rolls such that no more upgrades may occur during a maintenance window. The layer availability (e.g., a minimum layer availability) may indicate the available frequency layers required. The layer availability may ensure the end user (e.g., the consumer) experience during the upgrade period. In some examples, the one or more thresholds (e.g., one or more rollback thresholds) may indicate a change in drops (e.g., an increase in VoLTE/VoNR drops), throughput (e.g., a decrease in throughput), etc. The service management system may determine when to rollback an upgrade based on the one or more thresholds. 
     In some embodiments, the maintenance request may be received via a user interface. The user interface may include an image, button, drop down, menu, field, graphic, and/or any other suitable component that initiates the receipt of input corresponding to the maintenance request. 
     In some embodiments, the service management system may aggregate one or more network parameters associated with the at least one cell site. The service management system may receive the network parameter(s) based on the activity at the cell site(s). The one or more network parameters may include one or more performance indicators. As used herein, the term “performance indicator” may include a key performance indicator (KPI) such as, but not limited to, data traffic, voice traffic, and/or any other suitable indicator. The voice traffic may be based on calls such as, but not limited to, E911, Voice over LTE (VoLTE), Video over LTE (ViLTE), Voice over 5G (VoNR), Video over 5G (ViNR), erlangs (e.g., VoLTE, ViLTE, VoNR, and/or ViNR erlangs), drops (e.g., VoLTE, ViLTE, VoNR, and/or ViNR drops), and/or any other suitable voice traffic indicator. In some examples, the performance indicator (e.g., voice traffic such as, but not limited to, VoLTE, ViLTE, VoNR, and/or ViNR calls) may indicate customer calling trends and/or patterns. In some examples, the performance indicator (e.g., voice traffic such as, but not limited to, VoLTE, ViLTE, VoNR, and/or ViNR erlangs) may indicate network calling capacity. The performance indicator, in some examples, (e.g., voice traffic such as, but not limited to, VoLTE, ViLTE, VoNR, and/or ViNR drops) may indicate a period corresponding to a dropped call (e.g., a consistent period for dropped calls). The performance indicator (e.g., E911 calls) may indicate common high-priority traffic timing. 
     In some embodiments, the data traffic may be based on downlink traffic volume (e.g., LTE and/or NR), uplink traffic volume (e.g., LTE and/or NR), average user device throughput (e.g., LTE and/or NR), downlink PRB (Physical Resource Block) utilization, uplink PRB utilization, and/or any other suitable data traffic indicator. In some examples, the performance indicator (e.g., data traffic such as, but not limited to, downlink traffic volume) may indicate common data traffic timing. In some examples, the performance indicator (e.g., data traffic such as, but not limited to, uplink traffic volume) may indicate common data traffic timing. The performance indicator, in some examples, (e.g., data traffic such as, but not limited to, average user device throughput) may indicate user experience throughput trend(s). The performance indicator (e.g., downlink PRB utilization and/or uplink PRB utilization) may indicate network capacity tracking. 
     The service management system may learn and/or analyze the one or more network parameters. In some embodiments, the network parameter(s) may be aggregated and/or analyzed based on a single cell site or a plurality of cell sites. 
     In some examples, the service management system may generate one or more candidate maintenance windows based on the one or more network parameters aggregated and the maintenance requirement. The one or more candidate maintenance windows may identify one or more downtime upgrade periods correlating to at least one cell site. For example, the candidate maintenance windows generated may identify the candidate maintenance windows “4/28-10 PM-12 AM,” “4/29-3 AM-7 AM,” and/or “4/30-1 PM-4 PM” that correlate to the cell site  110 . The candidate maintenance window(s) may be generated in real-time or near real-time. 
     In some embodiments, the service management system may be structured to generate one or more confidence indicators. As used herein, the term “confidence indicator” may be used to refer to the likelihood that the maintenance window is not likely to result in reduction of performance indicators beyond a given performance threshold (e.g., beyond a given performance amount). Alternatively or additionally, the confidence indicator may indicate that within the maintenance window (e.g., within the specified allowed dates) it is the best time for the upgrade to occur. For example, the service management system may generate a confidence indicator “95%” for the candidate maintenance window “4/28-10 PM-12 AM,” a confidence indicator “91%” for the candidate maintenance window “4/29-3 AM-7 AM,” and/or a confidence indicator “83%” for the candidate maintenance window “4/30-1 PM-4 PM.” The confidence indicator(s) may take the form of one or more dynamic indicators that may update or otherwise change in value and/or weight as the candidate maintenance window approaches. Advantageously, the generation of the candidate maintenance window(s) optimizes the downtime of the network corresponding to one or more cell sites during an upgrade such that network performance impacts are reduced. 
     In some embodiments, the service management system may provide the candidate maintenance window(s) and/or the confidence indicator(s) to one or more user devices. The user device(s), via one or more user interfaces, may output, render, or otherwise display the candidate maintenance window(s) and/or the confidence indicator(s). 
     The service management system may be structured to generate a pre-check (e.g., a pre-upgrade check). The pre-check may be generated automatically or on-demand. The pre-check may be generated to alert the user of one or more cell sites that may or may not be in-sync (e.g., reached remotely), storage is available, etc. For example, the service management system may determine whether one or more nodes are in-sync, storage is available for an upgrade, etc. during the pre-check. In some examples, the service management system may determine whether one or more alarms are active or inactive during the pre-check. The service management system may provide the status of one or more parameters (e.g., the one or more nodes, storage availability, one or more alarms, etc.) determined during the pre-check to one or more user devices. The user device(s), via one or more user interfaces, may output, render, or otherwise display the status of the one or more parameters determined during the pre-check. 
     The service management system may be structured to generate a post-check. The post-check may be generated automatically or on-demand. In some embodiments, the service management system may determine whether one or more nodes have been upgraded. In some embodiments, the service management system  205  may determine the number of cell sites that are in an inactive state (e.g., a down state) to generate the post-check. In some examples, the service management system may determine the number of truck rolls per market to generate the post-check. If the cell site  110  is upgraded, the service management system  205  may generate a cleanup recommendation (e.g., a cleanup list that includes a list of sites unsuccessfully upgraded that require additional upgrade attempts). The service management system  205  may provide the post-check to one or more user devices. The user device(s), via one or more user interfaces, may output, render, or otherwise display the post-check. 
       FIG.  3    depicts a flow diagram of an exemplary method  300  for generating one or more candidate maintenance windows of at least one cell site of a telecommunications network, in accordance with implementations of the present disclosure. Initially at block  302  a maintenance request to upgrade the at least one cell site is received by the service management system. The maintenance request (e.g. a request to upgrade a cell site) may include at least one maintenance requirement (e.g., at least one schedule requirement or any other suitable requirement). In some embodiments, the schedule requirement may include one or more timing inputs (e.g., upgrade window, upgrade shutout, priority timing, maximum upgrade timing, etc.). The maintenance requirement may include one or more footprint requirements (e.g., a RAN input, footprint input, and/or rollback requirement). The maintenance request may be received via a user interface. 
     At block  304 , one or more network parameters associated with the at least one cell site is aggregated. The one or more network parameters may include one or more performance indicators (e.g., a key performance indicator (KPI) such as, but not limited to, voice traffic, data traffic, and/or any other suitable indicator). The voice traffic may be based on one or more calls (e.g., E911, VoLTE, ViLTE, VoNR, and/or ViNR calls), one or more erlangs (e.g., VoLTE, ViLTE, VoNR, and/or ViNR erlangs), one or more drops (e.g, VoLTE, ViLTE, VoNR, and/or ViNR drops) and/or any other suitable voice traffic indicator. The data traffic may be based on downlink traffic volume (e.g., LTE and/or NR), uplink traffic volume (e.g., LTE and/or NR), average user device throughput (e.g., LTE and/or NR), downlink PRB utilization, uplink PRB utilization, and/or any other suitable data traffic indicator. 
     In some embodiments, one or more candidate maintenance windows are generated based on the one or more network parameters aggregated and the maintenance requirement at block  306 . In some examples, the one or more candidate maintenance windows may identify one or more downtime upgrade periods correlating to at least one cell site. In some embodiments, the service management system may be structured to generate one or more confidence indicators that may update (e.g., update in value or weight) as the candidate maintenance window approaches. 
     Referring to  FIG.  4   , a block diagram of an example of a computing device  400  suitable for use in implementations of the technology described herein is provided. In particular, the exemplary computer environment is shown and designated generally as computing device  400 . Computing device  400  is but one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of the invention. Neither should computing device  400  be interpreted as having any dependency or requirement relating to any one or combination of components illustrated. In aspects, the computing device  400  may be a base station. In another embodiment, the computing device  400  may be UE capable of two-way wireless communications with an access point.

     The implementations of the present disclosure may be described in the general context of computer code or machine-useable instructions, including computer-executable instructions such as program components, being executed by a computer or other machine, such as a personal data assistant or other handheld device. Generally, program components, including routines, programs, objects, components, data structures, and the like, refer to code that performs particular tasks or implements particular abstract data types. Implementations of the present disclosure may be practiced in a variety of system configurations, including handheld devices, consumer electronics, general-purpose computers, specialty computing devices, etc. Implementations of the present disclosure may also be practiced in distributed computing environments where tasks are performed by remote-processing devices that are linked through a communications network. 
     As shown in  FIG.  4   , computing device  400  includes a bus  402  that directly or indirectly couples various components together. The bus  402  may directly or indirectly one or more of memory  404 , processor(s)  406 , presentation component(s)  408  (if applicable), radio(s)  410 , input/output (I/O) port(s)  412 , input/output (I/O) component(s)  414 , power supply  416 , and/or transmitter(s)  418 . Although the components of  FIG.  4    are shown with lines for the sake of clarity, in reality, delineating various components is not so clear, and metaphorically, the lines would more accurately be grey and fuzzy. For example, one may consider a presentation component(s)  408  such as a display device to be one of I/O components  414 . Also, the processor(s)  406  may include memory  404 , in another example. The present disclosure hereof recognizes that such is the nature of the art, and reiterates that  FIG.  4    is merely illustrative of an example of a computing device  400  that may be used in connection with one or more implementations of the present disclosure. Distinction is not made between such categories as “workstation,” “server,” “laptop,” “handheld device,” etc., as all are contemplated within the scope of the present disclosure and refer to “computer” or “computing device.” 
     Memory  404  may take the form of memory components described herein. Thus, further elaboration will not be provided here, but it should be noted that memory  404  may include any type of tangible medium that is capable of storing information, such as a database or data store. A database or data store may be any collection of records, files, or information encoded as electronic data and stored in memory  404 , for example. In one embodiment, memory  404  may include a set of embodied computer-readable and executable instructions that, when executed, facilitate various functions or elements disclosed herein. These embodied instructions will variously be referred to as “instructions” or an “application” for short. 
     Processor(s)  406  may be multiple processors that receive instructions and process them accordingly. Presentation component(s)  408 , if available, may include a display device, an audio device such as a speaker, and/or other components that may present information through visual (e.g., a display, a screen, a lamp (LED), a graphical user interface (GUI), and/or even lighted keyboards), auditory, and/or other tactile or sensory cues. 
     Radio(s)  410  represents one or more radios that facilitate communication with a wireless telecommunication network. For example, radio(s)  410  may be connected to one or more antenna elements through a physical path. Illustrative wireless telecommunications technologies include CDMA, GPRS, TDMA, GSM, and the like. Radio(s)  410  might additionally or alternatively facilitate other types of wireless communications including Wi-Fi, WiMAX, 3G, 4G, LTE, mMIMO, 5G, 6G, NR, VoLTE, and/or other VoIP communications. As can be appreciated, in various embodiments, radio(s)  410  may be configured to concurrently support multiple technologies, as previously discussed herein. As such, each of many radio(s)  410  may be used to separately control portions of an antenna array, for example, where at least one portion utilizes a distinct technology relative to another portion in the same antenna array or at the same base station or cell site. A wireless telecommunication network might include an array of devices, which are not shown so as to not obscure more relevant aspects of the invention. Components such as a base station, a communications tower, or even access points (as well as other components) can provide wireless connectivity in some embodiments. 
     The input/output (I/O) ports  412  may take a variety of forms. Exemplary I/O ports  412  may include a USB jack, a stereo jack, an infrared port, a firewire port, other proprietary communications ports, and the like. Input/output (I/O) components  414  may comprise keyboards, microphones, speakers, touchscreens, and/or any other item usable to directly or indirectly input data into the computing device  400 . 
     Power supply  416  may include batteries, fuel cells, and/or any other component that may act as a power source to supply power to the computing device  400  or to other network components, including through one or more electrical connections or couplings. Power supply  416  may be configured to selectively supply power to different components independently and/or concurrently. 
     Finally, regarding  FIGS.  1  through  4   , it will be understood by those of ordinary skill in the art that the environment(s), system(s), and/or methods(s) depicted are not intended to limit the scope of use or functionality of the present embodiments. Similarly, the environment(s), system(s), and/or methods(s) should not be interpreted as imputing any dependency and/or any requirements with regard to each component, each step, and combination(s) of components or step(s) illustrated therein. It will be appreciated by those having ordinary skill in the art that the connections illustrated the figures are contemplated to potentially include methods, hardware, software, and/or other devices for establishing a communications link between the components, devices, systems, and/or entities, as may be utilized in implementation of the present embodiments. As such, the absence of component(s) and/or steps(s) from the figures should be not be interpreted as limiting the present embodiments to exclude additional component(s) and/or combination(s) of components. Moreover, though devices and components in the figures may be represented as singular devices and/or components, it will be appreciated that some embodiments can include a plurality of devices and/or components such that the figures should not be considered as limiting the number of devices and/or components. 
     It is noted that aspects of the present invention are described herein with reference to block diagrams and flowchart illustrations. However, it should be understood that each block of the block diagrams and/or flowchart illustrations may be implemented in the form of a computer program product, an entirely hardware embodiment, a combination of hardware and computer program products, and/or apparatus, systems, computing devices/entities, computing entities, and/or the like carrying out instructions, operations, steps, and similar words used interchangeably (e.g., the executable instructions, instructions for execution, program code, and/or the like) on a computer-readable storage medium for execution. For example, retrieval, loading, and execution of code may be performed sequentially such that one instruction is retrieved, loaded, and executed at a time. In some embodiments, retrieval, loading, and/or execution may be performed in parallel such that multiple instructions are retrieved, loaded, and/or executed together. Thus, such embodiments can produce specifically-configured machines performing the steps or operations specified in the block diagrams and flowchart illustrations. Accordingly, the block diagrams and flowchart illustrations support various combinations of embodiments for performing the specified instructions, operations, or steps. 
     Additionally, as should be appreciated, various embodiments of the present disclosure described herein can also be implemented as methods, apparatus, systems, computing devices/entities, computing entities, and/or the like. As such, embodiments of the present disclosure can take the form of an apparatus, system, computing device, computing entity, and/or the like executing instructions stored on a computer-readable storage medium to perform certain steps or operations. However, embodiments of the present disclosure can also take the form of an entirely hardware embodiment performing certain steps or operations.
