Description

METHOD AND SYSTEM FOR MESSAGE ROUTING MANAGEMENT

TECHNICAL FIELD

[0001] Embodiments of the present disclosure generally relate to message routing management systems. More particularly, embodiments of the present disclosure relate to methods and systems for enhanced message routing management without any manual intervention.

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.

[0004] In the field of telecommunications, a network function is a functional building block within a network infrastructure that includes well-defined external interfaces and behaviour. Further the network function (implemented by server) is a key node in the network. Each network function communicates with one or more other network functions, both as “client” and as “server.” Whenever the network function acts as a client, it initiates requests towards server site. A server node is deployed in primary and secondary architecture to ensure high availability. A primary node of a network function is the main node whereas the second node of a network function is the auxiliary or redundant node.

[0005] When the primary node becomes unreachable or unable to serve the requests, the client may send the requests to the secondary node to prevent system failure and disruption of services. However, once the primary node becomes reachable again, there is a need to switch the traffic back to the primary node automatically without manual intervention because the continued use of the second node may lead to latency issues, etc.

[0006] It is emphasized that conventional approaches involve manually detecting the status of primary node and then manually switching the traffic from the secondary node to the primary node. In this approach, it is noted that the manual operator may not be able to detect the reachability of the primary node in time which may lead to continued use of low performing secondary node.

[0007] Thus, there exists an imperative need in the art for an enhanced solution for message routing management, which the present disclosure aims to address.

SUMMARY

[0008] This section is provided to introduce certain aspects of the present disclosure in a simplified form that are further described below in the detailed description. This summary is not intended to identify the key features or the scope of the claimed subject matter.

[0009] An aspect of the present disclosure may relate to a method for message routing management. The method comprises sending, by a transceiver unit, via a client node to a secondary node, a second connection request, in an event of a failure of connection establishment with a primary node. The method comprises determining, by a determination unit via the client node, a first status of a connection with the secondary node, wherein the first status is one of a positive first connection establishment status and a negative first connection establishment status. The method further comprises sending, by the transceiver unit, via the client node to a secondary node, a message traffic, in an event of the determination of the positive first connection establishment status. The method further comprises sending, by the transceiver unit via the client node to the primary node, a configurable number of ping requests, wherein the configurable number of ping requests are sent for establishing a connection with the primary node, and wherein the configurable number of ping requests are sent to the primary node for a pre-defined number of times. The method comprises receiving, by the transceiver unit, via the client node from the primary node, a positive feedback for at least a threshold number of the configurable number of ping requests, wherein the receipt of the positive feedback indicates a potential connection establishment between the client node and the primary node. The method comprises switching, by the transceiver unit, via the client node, the message traffic back to the primary node.

[0010] In an exemplary aspect of the present disclosure, the present disclosure comprises that prior to the sending, by the client node to the secondary node, the second connection request, the present disclosure comprises sending, by the transceiver unit, via the client node to the primary node, a first connection request, based on a set of configurable counters, wherein the first connection request is sent by the client node for a connection establishment with the primary node, for sending the message traffic to the primary node. The present disclosure further comprises determining, by the determination unit, via the client node, a second status of a connection with the primary node. The second status is one of a positive second connection establishment status, and a negative second connection establishment status. The positive second connection establishment status is determined in an event when a connection is established between the client node and the primary node, and the negative second connection establishment status is determined in an event when a connection is not established between the client node and the primary node. Further the determination of the negative second connection establishment status indicates the failure of connection establishment with the primary node.

The present disclosure further comprises switching, by the transceiver unit, the message traffic, to one or more proxy addresses in the primary list of proxy addresses in an event at least one proxy address from the primary list of proxy addresses is available. The present disclosure further comprises switching, by the transceiver unit, the message traffic, to one or more proxy addresses in the secondary list of proxy addresses in an event when the at least one proxy address from the primary list of proxy addresses is unavailable.

The transceiver unit is further configured to send, to the primary node, configurable number of ping requests. The configurable number of ping requests are sent for establishing a connection with the primary node. The configurable number of ping requests are sent to the primary node for a pre-defined number of times. The transceiver unit is further configured to receive, from the primary node, a positive feedback for at least a threshold number of the configurable number of ping requests. The receipt of the positive feedback indicates a potential connection establishment between the client node and the primary node. The transceiver unit is further configured to switch the message traffic back to the primary node.

[0015] Yet another aspect of the present disclosure may relate to a non-transitory computer readable storage medium storing instructions for message routing management, the instructions include executable code which, when executed by one or more units of a system, causes: a transceiver unit of the system to send to a secondary node, a second connection request, in an event of a failure of connection establishment with a primary node.

The configurable number of ping requests are sent for establishing a connection with the primary node, and the configurable number of ping requests are sent to the primary node for a pre-defined number of times. Further, the instructions include executable code which, when executed by one or more units of a system, causes the transceiver unit of the system to receive from the primary node, a positive feedback for at least a threshold number of the configurable number of ping requests, wherein the receipt of the positive feedback indicates a potential connection establishment between the user equipment and the primary node.

[0040] As discussed in the background section, that in the field of telecommunication, each network function communicates with one or more other network functions both as a client and a server. Whenever the network function acts as the client, it initiates request towards the server. A server node is deployed in a primary architecture and a secondary architecture to ensure high availability. A primary node of the network function is a main node whereas a secondary node of the network function is an auxiliary or a redundant node. Further, when the primary node becomes unreachable or unable to serve requests, the client may send the requests to the secondary node to prevent a system failure and disruption of services. However, once the primary node becomes reachable again, there is a need to switch the traffic back to the primary node automatically without manual intervention because continued use of the secondary node may lead to latency issues, etc. In addition to this, the currently known solutions are not able to detect reachability of the primary node in time which may lead to continued use of low performing node i.e., the secondary node. Hence, the current known solutions have several shortcomings. The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by providing a novel solution for message routing management. The present disclosure involves sending a connection request to a secondary node in an event of a failure of connection establishment with a primary node. Further, if the secondary node shows a positive status in response the connection request, a message traffic is then transmitted to the secondary node. Thereafter, a configurable number of ping requests are sent to the primary node for establishing a connection with primary node. Upon receiving a positive feedback from the primary node in response to the ping requests, the message traffic is routed from the secondary node to the primary node, without any manual intervention.

[0065] As used herein, “connection request” refers to a request for establishment of communication between two nodes for transmission of a message traffic in a network.

[0066] For example, in a telecommunication network, there are two nodes (i.e., the primary node [310] and the secondary node [306]). A user equipment (i.e., client node) sends a connection request to the primary node [310], however, due to a technical error, there is a failure in connection establishment between the client node, i.e., the user equipment, and the primary node [310], based on the connection request. In the event of failure of connection establishment with the primary node [310], the connection request is transmitted to the secondary node [306],

[0067] The present disclosure encompasses that the transceiver unit [304], prior to sending to the secondary node [306] the second connection request, is configured to send, to the primary node [310], a first connection request, based on a set of configurable counters. The first connection request is sent by the client node [302] for a connection establishment with the primary node [310], for sending a message traffic to the primary node [310], [0068] For example, the transceiver unit [304] is configured to send the first connection request to the primary node [310] for establishing a connection with the primary node [310], before sending the second connection request to the secondary node [306] based on the set of configurable counters.

[0069] As used herein, “message traffic” refers to a number of messages (i.e., requests, response) sent and received in the network during a communication procedure associated with the network.

[0070] The present disclosure encompasses that the set of configurable counters comprises one or more of a connection refused parameter, a connection timeout parameter, and a request timeout parameter Further, in an implementation of the present disclosure as disclosed herein, the set of configurable parameters may further comprise a retry threshold, one or more primary configuration, one or more secondary configuration, etc. It is to be noted that the set of configurable counters as disclosed herein are exemplary in nature.

[0122] The present disclosure further discloses a non-transitory computer readable storage medium storing instructions for message routing management, the instructions include an executable code which, when executed by one or more units of a system [300], causes: a transceiver unit [304] of the system [300] to send to a secondary node [306], a second connection request, in an event of a failure of connection establishment with a primary node [310], a determination unit [308] of the system [300] to determine a first status of a connection with the secondary node [306] wherein the first status is one of a positive first connection establishment status, and a negative first connection establishment status; the transceiver unit [304] of the system [300] to send to a secondary node [306], the message traffic, in an event of the determination of the positive first connection establishment status; the transceiver unit [304] of the system [300] to send to the primary node [310], a configurable number of ping requests, wherein the configurable number of ping requests are sent for establishing a connection with the primary node [310], and wherein the configurable number of ping requests are sent to the primary node [310] for a pre-defined number of times; the transceiver unit [304] of the system [300] to receive from the primary node [310], a positive feedback for at least a threshold number of the configurable number of ping requests, wherein the receipt of the positive feedback indicates a potential connection establishment between the user equipment and the primary node [310],

[0123] As is evident from the above, the present disclosure provides a technically advanced solution for message routing management. The present solution provides a solution that facilitates a seamless switch of a message traffic between two nodes without any manual intervention for reducing network disruptions. Further, if an initial connection request with an initial node fails, another connection request is transmitted to another node and in case another node shows positive feedback, then the message traffic is routed to the another node. Thereafter, a client node transmits a configurable number of ping requests to the initial node. Upon receiving positive feedback from the initial node in response to the ping requests, the message traffic is routed to the initial node. Hence, the switching or routing of the message traffic from one node to another node is done without any manual intervention that reduces one or more potential network disruptions. Further, the method and system of the present disclosure ensures an automatic redirection of the message traffic to the initial node (i.e., the primary node) without the need of manual intervention. Furthermore, present disclosure provides a solution that enables the message traffic to be shifted back to the initial node (i.e., primary node), thereby avoiding unforeseen latency at another node (i.e., secondary node). Hence, the present disclosure provides seamless message routing among a plurality of nodes, reduced network disruptions and automatic re-routing.
