Description

METHOD AND SYSTEM FOR TRANSMITTING PAGING MESSAGE FIELD OF THE DISCLOSURE [0001] The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for transmitting paging message. BACKGROUND [0002] The following description of 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 be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of 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. 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. [0004] Existing solutions in the telecommunications industry often struggle to efficiently manage the handover process when a User Equipment (UE) moves from an Evolved Packet System (EPS) network to a 5th Generation System (5GS) network. This challenge is particularly evident in the context of paging, where the network needs to send a signal to the UE to notify it of incoming data or calls. In the current state of the art, when a UE undergoes a handover from EPS to 5GS, the Access and Mobility Management Function (AMF) in the 5GS network lacks the necessary information to execute differential paging strategies based on the Data Network Name (DNN). This is because the AMF does not have access to the DNN name after the user has moved from EPS to 5GS using the N26 interface. Existing systems are unable to distinguish between different types of data networks, such as IMS (IP Multimedia Subsystem) and regular data networks, when paging UEs. This limitation leads to a one-size-fits-all approach to paging, which can be inefficient and result in suboptimal use of network resources. For example, paging for IMS services, which are often time-sensitive, cannot be prioritized over regular data services. As a result, the call setup time for IMS services may be longer than necessary, and the overall paging success rate may be lower than desired. Furthermore, existing systems do not allow for the customization of paging strategies based on the type of data network. This means that the network cannot adjust its paging approach to reduce the load on the Radio Access Network (RAN) or to improve the response time for specific services. Consequently, the network may experience unnecessary congestion, and the quality of service for users may be compromised. [0005] Thus, there exists an imperative need in the art to provide an efficient system and method for transmitting paging message.
