Description

METHOD AND SYSTEM FOR IMPLEMENTING A PLATFORM FOR ENCODING AND DECODING MESSAGES OF TARGET PROTOCOLS FIELD OF THE DISCLOSURE [0001] Embodiments of the present disclosure generally relate to the field of wireless communication systems. More particularly, embodiments of the present disclosure relate to a method and system for implementing a platform for encoding and decoding messages of target protocols. 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. In the 5G communication system, there is provided a plurality of network functions (NFs), for example an Access and Mobility Management Function (AMF), session management function (SMF), Authentication Server function (AUSF), a Network Slice Selection Function (NSSF), Policy control function (PCF), a Network Repository Function (NRF), and the like. One or more of the aforementioned NFs communicates with each other, to implement multiple activities on the 5G communication system. There are multiple interfaces/protocols for receiving and transmitting messages for the NFs such as the AMF and/or the SMF of 5G network. Each such interface/protocol has a large number of messages and each message has a large number of information elements. For example, Next Generation Application Protocol (NGAP), an Abstract Syntax Notation (ASN) 1.0 basic packed encoding rules (PER) based protocol, has 75 messages and 286 information elements, and SI Application Protocol (S1AP), another ASN 1.0 basic PER based protocol, has 72 messages and 120 information elements. [0004] For decoding and encoding of these messages, in the existing solutions a stack platform decodes and encodes messages that are received or transmitted by NFs such as the AMF and/or the SMF of 5G network. As a result, for different protocols, a separate stack with a large number of messages and information elements has to be developed in existing approaches. This is a labour intensive, a time-consuming and inefficient approach, particularly because where there are changes in any message or information element structure, the entire stack platform has to be again developed, tested and deployed. [0005] Further, information element and message-specific classes are defined in a stack platform and separate application programming interfaces (APIs) are needed for each message class and information element-specific class. Consequently, interfacing of stack platform with a core application ofthe NFs such as the SMF and/orthe AMF of5G network is complex and voluminous work due to large of number of APIs involved in said interfacing. [0006] Thus, there exists an imperative need in the art to develop a method and a system for implementing a platform for efficient and effective encoding and decoding of different ASN 1.0 basic PER based protocols, which the present disclosure aims to address. OBJECTS OF THE DISCLOSURE [0007] Some of the objects of the present disclosure, which at least one embodiment disclosed herein satisfies are listed herein below. [0008] It is an object of the present disclosure to provide a method and a system for implementing a platform for decoding and encoding of one or more messages of one or more Abstract Syntax Notation (ASN) 1.0 packed encoding rules (PER) based protocols.
