Description

METHOD AND SYSTEM FOR MANAGING A PERSISTENT CONNECTION

FIELD OF INVENTION

[0001] The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for managing the persistent connection.

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. 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] The present disclosure solves the problem related to the connection management - when a radio frequency is acting as a client (Hyper Text Transfer Protocol (HTTP) client), it requires some connections to be initiated from its end and based on the type of connections, a decision has to be taken whether that connection has to be a persistent connection or a non-persistent connection. None of the prior known solutions provides a clear solution designed to resolve Hyper Text Transfer Protocol/ Secure (HTTP/S) connection overload at a Network Resource Function (NRF) for Notification endpoints and to monitor/audit persistent connections required by application for forwarding requests to the NRF and/or a Probe server and/or a Security Edge Protection Proxy (SEPP) and hence this particular problem is not solved by the existing technical solutions.

[0005] Thus, there exists an imperative need in the art to efficiently manage the persistent connection, which the present disclosure aims to address.

Furthermore, to the extent that the terms “includes,” “has,” “contains,” and other similar words are used in either the detailed description or the claims, such terms are intended to be inclusive — in a manner similar to the term “comprising” as an open transition word — without precluding any additional or other elements.

[0030] As used herein, an “electronic device”, or “portable electronic device”, or “user device” or “communication device” or “user equipment” or “device” refers to any electrical, electronic, electromechanical and computing device. The user device is capable of receiving and/or transmitting one or parameters, performing function/s, communicating with other user devices, and transmitting data to the other user devices.

[0034] As portable electronic devices and wireless technologies continue to improve and grow in popularity, the advancing wireless technologies for data transfer are also expected to evolve and replace the older generations of technologies. In the field of wireless data communications, the dynamic advancement of various generations of cellular technology are also seen. The development, in this respect, has been incremental in the order of second generation (2G), third generation (3G), fourth generation (4G), and now fifth generation (5G), and more such generations are expected to continue in the forthcoming time.

[0035] Radio Access Technology (RAT) refers to the technology used by mobile devices/ user equipment (UE) to connect to a cellular network. It refers to the specific protocol and standards that govern the way devices communicate with base stations, which are responsible for providing the wireless connection. Further, each RAT has its own set of protocols and standards for communication, which define the frequency bands, modulation techniques, and other parameters used for transmitting and receiving data. Examples of RATs include GSM (Global System for Mobile Communications), CDMA (Code Division Multiple Access), UMTS (Universal Mobile Telecommunications System), LTE (Long-Term Evolution), and 5G. The choice of RAT depends on a variety of factors, including the network infrastructure, the available spectrum, and the mobile device's/device's capabilities. Mobile devices often support multiple RATs, allowing them to connect to different types of networks and provide optimal performance based on the available network resources.

[0036] As discussed in the background section, the current known solutions for connection management and auditing for persistent Hyper Text Transfer Protocol Secure (HTTP/S) connections have several shortcomings such as resolving a HTTP/S connection overload at a Network Resource Function (NRF) for Notification endpoints and to monitor/audit persistent connections required by application for forwarding requests to a the NRF and/or a Probe server and/or a Security Edge Protection Proxy (SEPP).

[0037] The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by providing a solution for managing Network Resource Function (NRF), wherein the client bifurcates between requirement of a persistent and a non-persistent connection based on endpoint details. The non-persistent connection is teared down to free system resources and audit the persistent connections in interval of configurable timer. The present solution restores the persistent connections, once found not available in audit. If restoring is unsuccessful, then it will raise corresponding alarm at a North-Bound Interface (NBI) for manual intervention. The Alarms maybe auto cleared once connection is re-established with remote host.

[0038] Hereinafter, exemplary implementations of the present disclosure will be described with reference to the accompanying drawings.

The system [200] as claimed in claim 8 wherein: the connection manager [208] is further configured to establish a non-persistent target connection in an event the required connection type is the non-persistent connection; the detection unit [210] is further configured to detect a successful transaction status associated with the non-persistent connection; and the connection manager [208] is further configured to terminate the non-persistent connection based on the detection of the successful transaction status.

15. A non-transitory computer-readable storage medium storing instructions for managing a persistent connection, the instructions comprising executable code which, when executed by one or more units of a system [200], causes: a transceiver unit [204] of the system [200] to receive, via an interface, a first connection request associated with a first end point, wherein the first connection request at least comprises a first end point configuration associated with the first end point; a determination unit [206] of the system [200] to determine a required connection type associated with the first connection request based on at least the first end point configuration, wherein the required connection type is at least one of the persistent connection and a non-persistent connection; a connection manager [208] of the system [200] to:

• initiate a connection monitoring timer associated with the first target connection, wherein the connection monitoring timer is configured for a pre-defined time; and a detection unit [210] of the system [200] to detect, a target connection status associated with the first target connection via monitoring periodically the first target connection based on the connection monitoring timer, wherein the target connection status is one of a target connection available status and a target connection unavailable status; and the connection manager [208] of the system [200] to re-establish with the first end point, the first target connection based on detecting the target connection unavailable status associated with the first target connection.
