METHOD AND SYSTEM FOR MONITORING AND MAINTAINING CONNECTIONS BETWEEN PEER NETWORK ENTITIESFIELD OF THE DISCLOSURE

[0001] The present disclosure relates generally to the field of wireless communication system. More particularly, the present disclosure relates to method and system for monitoring and maintaining connections between two or more peer network entities.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. 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] Existing techniques in the art of managing connections in a 5G network often suffer from a variety of challenges. Firstly, traditional connection management methods can be slow and inefficient, leading to delays in establishing and re-establishing connections between network functions (NFs). This is particularly problematic in scenarios with high traffic volumes or when quick recovery from lost connections is crucial. Secondly, there is often a bottleneck issue withactive traffic management. Current systems may not efficiently handle the dynamic nature of 5G network traffic, resulting in congestion and reduced network performance. Thirdly, many existing approaches lack robust mechanisms for periodic monitoring and managing reconnections. This can lead to prolonged periods of disconnection and service interruption, which is detrimental to the user experience and overall network reliability. Additionally, the conventional methods may not adequately support the complex requirements of 5G networks, such as the need for a scalable and flexible connection management system that can adapt to varying traffic patterns and network conditions. This inadequacy can hinder the effective utilization of network resources and the delivery of high-quality services to end-users.

[0005] Thus, there exists an imperative need in the art to provide an efficient system and method for monitoring and maintaining connections between peer network functions (NFs) or network entities, which the present disclosure aims to address.OBJECTS OF THE INVENTION

For example, a computer-readable medium includes read-only memory (“ROM”), random access memory (“RAM”), magnetic disk storage media, optical storage media, flash memory devices or other types of machine-accessible storage media. The storage unit stores at least the data that may be required by one or more units of the system to perform their respective functions.

[0035] 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 andreplace 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.

[0036] 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. The invention herein relates to the situations when the user equipment (UE) operates in the fifth generation (5G) communication system.

[0037] As used herein, worker thread unit refers to a component within the system that continuously monitors and maintains the connection sessions between peer network entities. The worker thread unit operates by utilizing one or more threads to perform its monitoring functions, ensuring that each connection session between the access and mobility management function (AMF) unit and the session management function (SMF) unit is actively supervised.

[0038] As used herein, connector thread unit refers to a component within the system tasked with the dynamic establishment of new connection sessions between peer network entities. The connector thread unit operates by leveraging one or more dedicated threads to initiate and configure connection sessions between the AMF unit and the SMF unit. Upon receiving instructions from the worker thread unit, particularly in response to detected inactivation triggers, the connector thread unit promptly establishes new connections to replace inactive or terminated sessions.

[0039] As used herein, thread refers to the smallest unit of execution within a process capable of being scheduled. The thread is a sequence of instructions that can be managed independently by a scheduler, which is typically a part of the operating system. The thread operates within a larger process and enables concurrent operations by executing specific tasks, such as monitoring connection sessions or establishing new connections. Threads share the process's resources, including memory and open files, but run independently, allowing for efficient multitasking and resource utilization.

[0040] As used herein, stream utilization refers to the measurement of the extent to which a communication stream's capacity is being used within a network connection. It quantifies the proportion of available stream resources that are currently occupied by active data transmissions between network entities, such as the AMF unit and the SMF unit. Stream utilization facilitates in assessing the efficiency and performance of network connections, as it indicates how much of the potential bandwidth is being effectively utilized for communication. High levels of stream utilization can signify optimal usage of network resources, whereas utilization nearing the upper thresholds, typically between 85-95%, may trigger the need for dynamic connection adjustments to prevent congestion and maintain performance. Monitoring stream utilization allows for proactive management of network traffic, ensuring that connections are established, maintained, or terminated in response to current network demands and conditions.

[0041] As used herein, connection roll strategy refers to a technique for managing and optimizing the establishment, maintenance, and termination of connection sessions between network entities to ensure efficient utilization of network resources. The connection roll strategy involves dynamically adjusting the number and distribution of active connections based on predefined criteria, such as stream utilization thresholds, traffic patterns, and network conditions. For example, when the utilization of a connection stream approaches a specified threshold, typically around 90%, the connection roll strategy may trigger the establishment of additional connections or reallocation of existing ones to balance the load and prevent congestion. By implementing a connection roll strategy, network systems can maintain high levels of reliability and efficiency, adapt to changing network demands, and optimize resource utilization for enhanced overall performance.

[0042] As used herein, traffic information refers to data and metrics that characterize the volume, type, and patterns of network traffic within a communication system. The traffic information includes, but is not limited only to, the number of active sessions, data transmission rates, packetsizes, latencyjiter, and the distribution of traffic across different network segments. Accurate and timely traffic information enables the dynamic adjustment of network configurations, such as establishing or terminating connection sessions, to ensure that the network can efficiently handle varying levels of demand and maintain reliable communication between network entities.

[0043] As used herein, an active connection session refers to an ongoing communication link between two or more network entities that are currently engaged in the transmission and reception of data. The active connection session comprises an established pathway through which data packets are exchanged. The connection sessions remain active as long as the communication requirements are met and no triggers for inactivation, such as session completion, timeouts, or network reconfigurations, are detected.

[0044] As used herein, stream refers to a continuous flow of data transmited over a network connection between two or more entities. The stream corresponds to a sequence of data packets that are sent from a source to a destination, maintaining the order and integrity of the transmited information. Streams are fundamental to ensuring reliable and ordered delivery of data, particularly in protocols such as HTTP / 2, where multiple streams can be multiplexed over a single TCP connection.

[0045] As discussed in the background section, existing techniques in the art of managing connections in a 5G network often suffer from a variety of challenges. Firstly, traditional connection management methods can be slow and inefficient, leading to delays in establishing and re-establishing connections between network functions (NFs). This is particularly problematic in scenarios with high traffic volumes or when quick recovery from lost connections is crucial. Secondly, there is often a botleneck issue with active traffic management. Current systems may not efficiently handle the dynamic nature of 5G network traffic, resulting in congestion and reduced network performance. Thirdly, many existing approaches lack robust mechanisms for periodic monitoring and managing reconnections. This can lead to prolonged periods of disconnection and service interruption, which is detrimental to the user experience and overall network reliability. Additionally, the conventional methods may not adequately support the complex requirements of 5G networks, such as the need for a scalable and flexible connection management system that can adapt to varying traffic paterns and network conditions. This inadequacy can hinder the effective utilization of network resources and the delivery of high- quality services to end-users.

[0046] The present disclosure addresses the problems in the art by introducing a method and system for managing connections between peer network entities in a 5G network. Existing techniques often suffer from slow and inefficient connection management, bottleneck issues with active traffic, lack of robust mechanisms for periodic monitoring and reconnections, and inadequacy in supporting the complex requirements of 5G networks. The disclosed method dynamically establishes and monitors connection sessions between network functions, such as the access and mobility management function (AMF) and the session management function (SMF), using separate thread units for connection establishment and monitoring. This approach allows for fast and efficient connection management, reducing delays in establishing and re-establishing connections. By utilizing a configurable predefined number of connection sessions based on traffic information, the disclosed method alleviates bottleneck issues with active traffic, ensuring smooth and uninterrupted network performance. The method further includes mechanisms for periodic monitoring and managing reconnections, minimizing service interruptions and enhancing network reliability. The dynamic establishment of new connection sessions based on various triggers, such as discovery, notification, inactivation, traffic, and stream utilization, allows the system to adapt to varying traffic patterns and network conditions. This flexibility supports the complex requirements of 5G networks, facilitating effective utilization of network resources and delivery of high-quality services to end-users.

[0047] It would be appreciated by the person skilled in the art that the present disclosure resolves the problems in the art by providing a more efficient, flexible, and robust system and method for managing connections in a 5G network, leading to improved network performance and user experience.

[0108] , however it may be obvious to a person skilled in the art that the concepts of the present disclosure may also extend to the communication between other peer NF s or network entities.

[0067] FIG. 2 illustrates an exemplary block diagram of a network architecture

[0108] based on a traffic information on exemplary network architecture, for establishing the communication therebetween. The predefined number of connections

[0202] corresponds to communication connections / links defined by user or network operator based on based on local configuration of network traffic requirements.

[0069] In an exemplary aspect, the user / network operator may reserve minimum number of configurable predefined communication connections for specific applications. The specific application may include but not limited to, voice traffic or data traffic. In an exemplary aspect, the user / network operator may reserve minimum number of ranges of configurable predefined active communication connections for managing the network traffic. For example, a user or network operator may set aside a certain number of communication connection ranges specifically for voice traffic. For instance, they might reserve 10-20 connection ranges exclusively for voice calls to ensure high-quality voice communication even during peak traffic times. Similarly, the user or network operator could allocate a specific number of connection ranges for data traffic, such as 30-50 ranges, to manage data-intensive applications like video streaming or large file transfers effectively. Moreover, the user or network operator has the flexibility to dynamically adjust the number of reserved connection ranges for network traffic management based on real-time requirements. For example, during a major event or emergency, they might increase the number of active connection ranges dedicated to emergency services to ensure uninterrupted communication.

[0310] , the method

[0300] as disclosed by the present disclosure comprises dynamically establishing, by the connection establishing unit

[0206] via a connector thread unit

[0214] , a new connection session between the access and mobility management function (AMF) unit

[0106] and the session management function (SMF) unit

[0300] terminates at step

[0312] ,

[0087] In an exemplary aspect of the present disclosure, the connections management may also be performed between any two other peer networks functions (NFs) or network entities also. The present disclosure is not limited to only connection management between AMF unit

[0106] and SMF unit

[0108] ,

[0088] For example, in a 5G core network, the Access and Mobility Management Function (AMF) and the Session Management Function (SMF) need to exchange signalling information to manage user sessions and mobility. Suppose the network has a capacity of 1000 streams for communication between the AMF and SMF. During a busy period, the AMF and SMF might be actively utilizing 850 of these streams to handle tasks such as session management, mobility updates, and policy control, resulting in a stream utilization of 85%. If a sudden increase in network activity occurs, the utilization might rise to 950 streams, pushing the stream utilization to 95%. The high level of utilization indicates that most of the available capacity is being used, potentially leading to congestion. To prevent this, the network could dynamically allocate more streams or optimize the use of existing ones to ensure efficient communication. Monitoring and managing stream utilization between the AMF and SMF helps maintain optimal performance and avoid bottlenecks in the network.
