METHOD AND SYSTEM FOR OPTIMIZATION OF DEVICE TRIGGERING PROCEDURE FOR IoT DEVICES FIELD OF INVENTION

[0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to a method and a system for optimization of device triggering procedure for the Internet of Things (IoT) device(s) in exposure function. 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 analogue 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] IoT (Internet of Things) devices are physical objects embedded with sensors, software, and connectivity features that enable them to collect, exchange, and act upon data with minimal human intervention. The IoT devices are interconnected through the internet or other communication networks to enable remote monitoring, control, and automation of various tasks.Further, the Internet of Things (IoT) devices such as wearable technologies, smart locks, smoke detectors, home automation devices, motion Detectors etc., are connected to Communication servers in order to send alerts, notifications, and / or information about various events such as trespass, accidental falls, burglary etc. In a communication network (preferably a 5G communication network), all the IoT devices perform various task such but not limited to handling loads, introduction of new 5G use cases, etc. In a 5G communication network, the IoT devices communicate with each other via Network Exposure Functions (NEF) through a process facilitated by the NEF's capabilities to expose network resources and services. The Network exposure (sometimes exposure function), or service exposure refers to the functionality of the communication network that helps in making network capabilities, such as data and network services, easily available for communication service providers and third parties. The exposure function is responsible for securely exposing the network capabilities to application function. The NEF acts as an intermediary that enables IoT devices to access and utilize network functions, data, and resources provided by the underlying network infrastructure. This is done with the help of standardized Application Programming Interfaces (APIs) exposed by the NEF. The IoT devices can interact with each other, exchange data, and collaborate on various applications and services with the help of exposure function. For e.g., a communication done between Application Programming Interfaces (APIs) by sharing data via a Service Capability Exposure Function (SCEF) / NEF from the Capability Server (CS) / Application Server (AS) / Application Function (AF). The APIs provided by the Exposure Functions may include but not limited to Subscriber Data API, QoS (Quality of Service) Management API, Session Management API etc. These APIs are generally configured on predefined rules and conditions such as standardized protocols and are exposed by the Exposure Function to authorized third-party applications through secure authentication and authorization mechanisms. The SCEF is responsible for exposing network capabilities and services to authorize third-party applications. The SCEF provides standardized APIs for accessing network functions, data, and resources, enabling developers to create innovative services and applications. While the NEF serves as an interface between the network infrastructure and external applications in the 5G environment. It exposes network resources and services through standardized APIs, allowing authorized third-party applications to access and utilize network functions, data, and resources for various use cases, such as IoT deployments, edge computing, and service innovation.

[0005] A device triggering request refers to a signal / prompt sent from one device (preferably an IoT device) to another IoT device to perform a specific task or action. The device triggering request is governed as per a predefined protocol that is required in implementation of the receiptof the device triggering request thus ensuring seamless interaction and optimal performance of the communication network. The data shared by the APIs via the SCEF / NEF is to be encoded with Data-Coding-Scheme (DCS) for device trigger payload. The DCS here refers to a parameter that specifies the encoding and formatting scheme used for representing data. The DCS defines how the data is structured, encoded, and interpreted by the network elements. It may include information such as data format, compression method, character set, and error detection / correction mechanisms, allowing efficient and reliable transmission of trigger-related information between the IoT devices and network components. Further, the device trigger payload refers to the data / information included in a message sent from a service consumer such as but not limited to Services Capability Server / Application Server and an Application Function. The device trigger payload helps in initiating a specific action or event in one or more Internet of Things (IoT) devices. The device trigger payload typically contains instructions, parameters, or identifiers necessary in the predefined protocols of the device triggering request, for the targeted IoT devices to perform the desired action. The payload may include various types of data, such as configuration settings, commands, or status updates, depending on the specific requirements of the triggering operation. However, for device triggers sent from SCEF / NEF, the 3rd Generation Partnership Project (3GPP) standard has no clarity on the DCS to be configured for the device trigger payload. Therefore, the SCEF / NEF does not get the information from the SCS / AS / AF to allow the data to be conveyed via SCEF / NEF about the intended DCS for the data to be shared using the APIs. With the existing solutions, the SCEF / NEF are configured to share data of a pre-defined DCS format only because of limitation of the existing 3GPP standard specification. Any data shared which is not of the pre- defined DCS format does not reach the intended target which, in turn, leads to failure of data transmittal.

[0006] Further, a device trigger procedure for the IoT device in the 5G communication network refers to the sequence of actions and signalling processes involved in initiating a specific action or event. The device trigger procedure typically includes the transmission of trigger commands or messages from a service consumer to the targeted IoT devices, thereby triggering the execution of predefined tasks or operations, such as data collection, device activation, or event reporting.

[0007] Furthermore, over the period of time, various solutions have been developed to improve the performance of communication devices for enhancement in device triggering procedure for IoT device(s) to specify / configure intended Data-Coding-Scheme (DCS) for each Services Capability Server (SCS) / Application Server (AS) / Application Function (AF) to allowthe data to be conveyed via Service Capability Exposure Function (SCEF) or Network Exposure Function (NEF) to one or more intended IoT Devices. However, there are certain challenges with existing solutions. The existing solutions, as well as the 3GPP standard, do not provide clarity on how to trigger an IoT device to share data with an intended DCS.

[0008] Thus, in order to improve the 3GPP communication standard, there exists an imperative need in the art for enhancement in device triggering procedure for an IoT device to specify / configure intended DCS for each Services Capability Server (SCS) / Application Server (AS) / Application Function (AF) to allow the data to be conveyed via Service Capability Exposure Function (SCEF) or Network Exposure Function (NEF) to one or more intended IoT Devices. The present disclosure aims to address this problem. SUMMARY OF THE DISCLOSURE
