Description

METHOD AND SYSTEM FOR AUTOMATIC UPGRADE OF SOFTWARE FOR NETWORK ELEMENTS

FIELD OF INVENTION

[0001] Embodiments of the present disclosure generally relate to software upgradation for one or more network elements. More particularly, embodiments of the present disclosure relate to a method and system for an automatic upgrade of a software for the one or more network elements.

BACKGROUND

[0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.

[0003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. The third- generation (3G) technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth-generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth-generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users.

[0004] Various solutions have been developed to upgrade software and firmware of wired and wireless communication network elements. The conventional and existing solution technologies include manual software upgrade and manual firmware upgrade of network elements which require multiple set of steps to execute on network element system(s). Such execution may be done via manual login to a corresponding management system which handles minimal number of network elements. This manual software or firmware upgrade of network elements could take months to upgrade all the nodes of network to the target software version.

[0005] Therefore, there is a need in the art to provide a system and method for an automatic upgrade of a software for one or more network elements and upgrade, at scale, the firmware in the network without human interference.

[0052] The system [300] is configured for the automatic upgrade of the software for the one or more network elements [134], with the help of the interconnection between the components/units of the system [300],

[0053] The present disclosure provides the automatic upgrade of the software for the one or more network elements [134], The automatic upgrade refers to the upgradation of software elements that are used by the one or more network elements [134] for enhancement of the software. The software for one or more network elements [134] are the set of instructions, data or programs that are used to operate and execute specific tasks in the one or more network elements [134], The one or more network elements [134] are the one or more network nodes or facilities/equipment that are used within the telecommunication network.

Further, in another example, the one or more network elements may also be a server, a network slice instance, a microservice, etc. [0054] Initially, the identifier unit [302] is configured to identify the one or more network elements [134] for performing software upgrades. Performing software upgrades, as used herein, refers to installing a software which provides enhancement of the software used by the one or more network elements [134], For performing software upgrades, the present disclosure provides identifying the one or more network elements [134] that requires upgradation of software.

[0055] The present disclosure further discloses that, for identifying the one or more network elements [134], the identifier unit [302] may also configured to select a list of vendors, then select a list of one or more network elements [134], thereafter, mapping the relevant or latest software version and generating work order for upgrade. Then, selecting network element details and enabling bulk operation for the software upgrade.

[0056] In one example, the identifier unit [302] may select the list of the vendors. The vendor devices can exist in multiple generations (4G, 5G, 6G . . . nG) of cellular networks. Then, for selecting the list of one or more network elements [134] in multiple generation of cellular networks having multiple network element types, the identifier unit [302] may be configured to identify one or more network elements [134] within each generation of network element type. Further, the end user can select a subset of select network element(s) for upgradation based on different logical choices (such as network area coverage, location criticality, etc.).

[0057] For mapping the relevant or latest software version that the one or more network elements [134] are required to be upgraded. Each Vendor Network Element Type will have a unique Software Version that is required to be upgraded or installed at the network elementfl 34], Each unique software version may have a one-to-one association with a unique recipe.

[0058] For generating work orders related to performing software upgrades, Work Order having differing number of Network Elements of different Network Element Types are opted for upgrading to different version along with their recipes.

[0059] For selecting network element details and enabling bulk operation, the system will automatically pick the selected network element details and enable the bulk operation. The above listed fields can be tweaked or configured based on Operations and Management (O and M) admin choices. Target nodes are grouped together based on different regions and/or admin options (EMS) such as District-wise/State-wise/Country-wise, EMS across region and Individual EMS. The target node may refer to the nodes or the one or more network elements [134] that are identified or selected for performing software upgrade. For example, the target nodes are selected based on a geographical area and the network element for a state are required to be updated. Now, the entire one or more network elements [134] within such geographical area may be selected as the target nodes, and then may be used for performing software upgrades.

[0060] On identification of the one or more network elements [134], the analysis unit [304] is configured to determine one of a positive satisfaction and a negative satisfaction of one or more pre-checks on each of the one or more network elements [134], wherein the positive satisfaction is determined based on a success of the one or more pre-checks and the negative satisfaction is determined based on a failure of the one or more pre-checks. The one or more pre-checks refer to checking of one or more parameters before performing software upgrades. The positive satisfaction is a positive response from the one or more pre-checks based on the success of the prechecks. The negative satisfaction is a negative response from the one or more pre-checks based on the failure of the pre-checks. The success and the failure of the pre-checks are the outputs of the pre-checks after the pre-checks have been performed and indicates the outputs of the pre-checks.

[0061] The one or more pre-checks comprises a memory availability, a central processing unit (CPU) utilization, a health check, a system requirement check, and a backup configuration check. The memory availability refers to a check related to availability of storage/ space for storing additional data. For example, for memory availability check, the positive response would be existence of additional storage space in the memory unit of the one or more network nodes, and the negative response would be non-availability of additional storage for performing software upgrades. The central processing unit (CPU) utilization is the amount of load on an individual processor cores for running various programs on the one or more network nodes. For example, if the amount of load/ CPU utilization is high, then it may be that the CPU cannot be used for performing software upgrade and this will be the negative response, however, if the CPU utilization is lower, then it can be used for performing software upgrade, which will result in a positive response. The health check refers to checking of a health status of the one or more network nodes which checks if the one or more network nodes are performing effectively and efficiently which can be done by evaluation of the Quality of Service provided by the one or more network nodes. For example, a positive response for the health check would be if the one or more network nodes are healthy, and if the one or more network nodes are not healthy, then it would be considered as the negative response. The system requirements check is a test which verifies the hardware and the software installed in the one or more network nodes and identifies if the one or more network nodes are capable of performing software upgrades without any error based on the predefined system requirements. The predefined system requirement can be dynamically defined based on the software upgrade. For example, a positive response for system requirement check is if all the hardware and software are verified based on one or more predefined system requirements, and in case the hardware and software is not verified then it would provide a negative response. The backup configuration check comprises checking whether the one or more network nodes has a backup configuration for handling any errors in the software upgrades. For example, a positive response would be if the backup configuration exists, otherwise it would be a negative response.

[0062] Also, after identification of the one or more network elements [134], the analysis unit [304] is further configured to determine an existence or a non-existence of one or more critical alarms. The one or more critical alarms may be on the one or more network elements [134], The determination of existence or non-existence of the one or more critical alarms are based on an extraction of a log received from the one or more network elements [134], The one or more critical alarms refer to the indication that there may be one or more issues in the one or more network elements [134], The existence of the one or more critical alarms is the presence of one or more issues in the one or more network elements [134] based on the one or more critical alarms. The non-existence of the one or more critical alarms is the presence of the one or more issues in the one or more network elements [134] based on the one or more critical alarms. For checking the one or more critical alarms the one or more network elements [134] are sent a command to extract the alarms along with the corresponding details of the one or more network elements [134], The one or more network elements [134] send the log that is a detailed log file which contains a record of events that occurred in the one or more network elements [134], the events may also contain information associated with functioning of the one or more network elements [134], The determination of the existence or non-existence of the one or more critical alarms can be determined based on extraction and evaluation of the log, and then analysing the record of events in the detailed log file. Furthermore, a trap event is caused due to occurrence of an interrupt during functioning of the one or more network elements [134], The network node may, while transmission of the log, convert the log into a compressed or encrypted format, and then while the analysis unit [304] receives the compressed or encrypted format from the one or more network elements [134] for obtaining the log or extraction of the log, the analysis unit may decompress or decrypt that format and extract the log for obtaining such information associated with existence or nonexistence of one or more critical alarms. [0063] After determination of the one or more pre-checks and the one or more critical alarms, the analysis unit [304] is further configured to download the software in an event of the positive satisfaction of the one or more pre-checks and the non-existence of the one or more critical alarms. Based on the determination of non-existence of the one or more critical alarms by the analysis unit [304], and determination of positive satisfaction of the one or more pre-checks, it is determined whether the one or more network elements [134] are ready for performing the software upgrade. After the one or more network elements [134] are ready, the files containing software may also be downloaded on the one or more network elements [134],

[0064] In case of positive satisfaction of the one or more pre-checks and the non-existence of the one or more critical alarms, the transceiver unit [306] is configured to send to a vendor system, a software upgrade request for upgrading a network element from the one or more network elements [134] in cases where the one or more network elements [134] belong to an external network. The software upgrade request is a request for performing software upgrade of the one or more network elements [134], Anetwork element is a network nodes or facility/equipment that is used within the telecommunication network. The vendor system can be a vendor management system or an element management system which manages the one or more network elements [134], In case the one or more network elements [134] are owned or managed by a vendor or external party, the software upgrade request is sent to the vendor system. The external network refers to the part of network which is owned or managed by a separate entity.

[0065] In case of the negative satisfaction of the one or more pre-checks and the existence of the one or more critical alarms, the analysis unit [304] is further configured to perform in real time, one or more from a re-attempt function, a cancel function, an abort function, and a reboot function in an event of the negative satisfaction and the existence of the one or more critical alarms. The re-attempt function is an attempt for performing software upgrade of the one or more network elements [134] again. The cancel function is cancelling the attempt for performing software upgrade. The abort function is aborting the attempt for performing the software upgrade. The reboot function is rebooting the software of the one or more network elements [134], The event of the negative satisfaction and the existence of the one or more critical alarms is the case when the one or more pre-checks results in negative satisfaction or negative response, and there is an existence of the one or more critical alarms. This is a scenario where if there are any issues which may lead to inability of performing the software upgrade, the one or more network elements [134] are required to perform the above-mentioned functions for enabling the one or more network elements [134] to perform the software upgrade. The above-mentioned functions are performed in real-time to solve the problems in the one or more network nodes and make them capable for performing the software upgrade without requiring any manual intervention.

[0066] Once the software is downloaded, the analysis unit [304] is further configured to perform one or more post-checks on the each of the one or more network elements [134], The one or more post-checks are the test performed on each of the one or more network elements [134] after said performing software upgrade of the one or more network elements [134],

[0067] The one or more post-checks comprises one or more of a software version check, and a performance metrics check. The software version check is a test which checks for the information associated with the software version and may also contain the information associated with last upgrade of the one or more network elements [134], The performance metrics check comprises measuring one or more key performance metrics comprising a throughput metric, a latency metric, and a capacity metric. The throughput metric refers to the amount of data which is transferred across the telecommunication network from a source to a destination, over a period of time. The latency metric is the delay or time taken in the transfer of the data from the source to the destination. The capacity metric is the capability or amount of traffic that can be handled by the one or more network elements [134],

[0068] The present disclosure further discloses that the upgrading of the network element from the one or more network elements [134] is performed based on a stage associated with said network element. The present disclosure also provides that performing software upgrades can also be done in stages, where a predefined count of network elements [134] from the one or more network elements [134] can be selected for performing software upgrades, and after performing software upgrades for the predefined count of network elements [134], the one or more network elements [134] that are next to the predefined count of network elements [134] from the one or more network elements [134] are then considered for performing software upgrades. Since, the one or more network elements [134] cannot be used for providing any service during the performance of the software upgrades, the performance of software upgrades stage-wise allows for continuous usage of the telecommunication network without interrupting the service of the telecommunication network, and the software upgrade can be automatically installed. There may be various stages for performing software upgrade. For example, a predefined count of the one or more network elements [134] can be upgraded in a first stage, thereafter, at next stage another predefined count of the one or more network elements [134] can be upgraded. There can be various stages based on the total availability and requirements of one or more network elements [134], Finally, at last stage, the remaining count of the one or more network elements [134] may be upgraded.

[0069] The present disclosure further discloses that the event of the upgrading of the network element from the one or more network elements [134], a coverage area associated with said network element is assigned to one or more other network elements [134], The coverage refers to the geographical region which is covered by the one or more network elements [134] for providing the service for telecommunication networks. In order to avoid interrupting the service provided by the one or more network elements [134], the identification of the one or more network elements [134] for performing software upgrade is such that the one or more network elements [134] that can provide the services of telecommunication network for the same coverage area are not identified for performing software upgrades. Such one or more network elements [134] would be selected in another stage in case of stage-wise software upgrades. Such one or more network elements [134] can remain active for providing services in the coverage area while the software for the identified one or more network elements [134] are being upgraded.
