Abstract

The present disclosure provides a system (100) and method for policy control function (PCF) (116) based short messaging service (SMS) delivery. The method provides the PCF (116) interacting with a SMSC Gateway server (120) over SMPP interface to provide the SMS. The PCF (116) initiates a connection with both primary and secondary SMSC Servers at start-up. PCF (116) sends messages on the available connections, prioritizing the primary SMSC server. If the connections are established but the requests are getting timed out, then PCF (116) disconnects from the SMSC server from which it is getting timeouts based on the configurable threshold.

SYSTEM AND METHOD FOR POLICY CONTROL FUNCTION (PCF) BASED SHORT MESSAGE SERVICE (SMS) DELIVERY RESERVATION OF RIGHTS [0001] A portion of the disclosure of this patent document contains material, which is subject to intellectual property rights such as, but are not limited to, copyright, design, trademark, Integrated Circuit (IC) layout design, and/or trade dress protection, belonging to Jio Platforms Limited (JPL) or its affiliates (hereinafter referred as owner). The owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all rights whatsoever. All rights to such intellectual property are fully reserved by the owner. FIELD OF DISCLOSURE [0002] The embodiments of the present disclosure generally relate to a message delivery system in a communication network. In particular, the present disclosure relates to a system and method for policy control function (PCF) based short messaging service (SMS) in a communication network. DEFINITION [0003] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used to indicate otherwise. [0004] The expression ‘Barring Area’ used hereinafter in the specification refers to an area where access to specific services or network functionalities may be restricted or barred for various reasons. These reasons could include network congestion management, security concerns, regulatory requirements, or service prioritization. For instance, in a high-traffic area, network operators might implement barring to limit access to non-essential services or to prioritize critical services like emergency calls. Barring Area refer to a geographical location where a specific type of communication or service is not available or is blocked, typically due to technical or operational limitations. The location may be an isolated area, a rural or remote region, or even a specific building or structure that interferes with the network's signal. Barring areas may be temporary or permanent, and there may be measures in place to address issues such as network congestion, service disruptions, and security breaches. [0005] The expression ‘Non-Barring Area’ used hereinafter in the specification refers to an area where no such access restrictions are imposed, allowing mobile devices and users to access all available services and network functionalities without any limitations. Non-barring areas are typically regions where network capacity is sufficient to accommodate all users and services without the need for prioritization or restriction. Non-barring area does not experience any obstruction or interference in the network's transmission of data, such as physical barriers or congested routes. The non-barring area is characterized by high network performance, low latency, and high data transfer rates. Identifying non-barring areas is critical for network optimization and improving overall performance. [0006] The expression ‘Tracking Area Code (TAC)’ used hereinafter in the specification refers to a unique identifier assigned to a group of base stations or cells within a certain geographical area. Mobile devices use the TAC to manage handovers between different cells as they move through the network. [0007] The term “SMF” used hereinafter in the specification refers to session management function for collecting information related to packet data unit (PDU) session management from various network components in the 5G core network. [0008] The term “PCF” used hereinafter in the specification refers to policy control function specifying policy rules for application and service data flow detection, gating, QoS, and flow-based charging to the SMF. [0009] The term “AMF” used hereinafter in the specification refers to access and access and mobility management function providing control plane network functions (NF) of the 5G core network. [0010] The term “SMPP” used hereinafter in the specification refers to Short Message Peer to Peer protocol for providing a flexible data communications interface for transfer of short message data between a Message Centre, such as a Short Message Service Centre (SMSC) and other messaging gateway. [0011] The term “SMSC” used hereinafter in the specification refers to short message service centre providing services of a SMPP server. [0012] The term “SMS” used hereinafter in the specification refers to short message/messaging service messages. [0013] These definitions are in addition to those expressed in the art. BACKGROUND OF DISCLOSURE [0014] 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 apprecia
