Description

METHOD AND SYSTEM FOR EXTRACTING DESIRED SIP PACKETS AT SIB NODE SERVER

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 extracting desired Session Initiation Protocol (SIP) packets at System Information Block (SIB) node/node server.

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] A System Information Block (SIB) node/ node server provides functionality of Serving Call Session Control Function (S-CSCF), Interrogative Call Session Control Function (I-CSCF) and Breakout Gateway Control Function (BGCF) as defined in 3GPP standards. The SIB node receives Session Initiation Protocol (SIP) compatible packets. In a conventional SIB node, due to high network traffic, capturing and analyzing the traffic /relevant SIP packets becomes challenging. This leads to problem in identifying packet as there is no way to identify/ filter the relevant packets after users/ subscribers raised a complaint to a network operator. The network operator (also known as a telecom service provider or carrier) include traditional telecommunications companies (telcos), mobile network operators (MNOs), internet service providers (ISPs), cable companies, and satellite communication providers. These operators may operate on a local, regional, national, or international scale, serving residential, business, and government customers with communication services. As a result, to troubleshoot or debug a user raised complaint, the network operator had to extract all SIP packets arriving at SIB node. Since the network traffic is generally high, a large amount of data had to extracted to a database connected to/part of SIB node server. As a result, troubleshooting or debugging an issue would be resource intensive, time consuming and inefficient process due to prohibitively voluminous data involved in the same. In the existing technologies, there is no way to identify/filter desired/relevant SIP packets at SIB node server.

[0005] Thus, there exists an imperative need in the art to extract only desired SIP packets at SIB node server, which the present disclosure aims to address.

[0008] It is another object of the present disclosure to provide a solution that extracts the desired SIP packets efficiently for a particular subscriber or group of subscribers for debugging or trace routing purposes.

[0009] It is another object of the present disclosure to provide a solution that enables faster debugging or troubleshooting of subscriber related issues by extracting only the desired SIP packets at the SIB node server. [0010] It is another object of the present disclosure to provide a solution that is less resource intensive, faster and more efficient as compared to prior art approaches of analysing entire network traffic.

[0011] It is yet another objective of the present disclosure to logically combine different headers of the network packets to extract more relevant SIP packets.

[0034] Further, the user device and/or a system as described herein to implement technical features as disclosed in the present disclosure may also comprise a “processor” or “processing unit,” wherein processor refers to any logic circuitry for processing instructions. The processor may be a general -purpose processor, a special purpose processor, a conventional processor, a digital signal processor, a plurality of microprocessors, one or more microprocessors in association with a DSP core, a controller, a microcontroller, Application Specific Integrated Circuits, Field Programmable Gate Array circuits, any other type of integrated circuits, etc. The processor may perform signal coding data processing, input/output processing, and/or any other functionality that enables the working of the system according to the present disclosure. More specifically, the processor is a hardware processor.

[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 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.

[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.

[0037] A Serving Call Session Control Function (S-CSCF) is the primary node implemented by a server in an IMS responsible for session control. Subscribers are allocated a S-CSCF for the duration of their IMS registration in order to facilitate routing of SIP packets as part of service establishment procedures. The Session Initiation Protocol (SIP) refers to a set of rules for initiating and terminating a communication session. The communication session includes but may not be limited to a voice communication, a text communication, and a video communication. In the context of the Session Initiation Protocol (SIP), the IP packets refer to the basic fundamental units of data that are transmitted thereby facilitating the exchange of signalling messages and media streams between SIP endpoints over IP networks. These IP packets contain various types of data, including but not limited to SIP signalling messages, media streams and other related information for transmission between the SIP endpoints. Consequently, the S-CSCF downloads a subscriber profile from the HSS (Home Subscriber Server) at the time of registration, which allows the S- CSCF to ascertain a relevant Application Server (AS) for a service request. The relevant Application Server (AS) may be required to handle the service request to ensure that the service request may be accurately processed.

[0038] An Interrogating Call Session Control Function (I-CSCF) implemented by a server is responsible for onward routing of SIP packets to the appropriate S-CSCF for a given subscriber. This routing capability is utilized in specific scenarios only, such as during registration in order to assign or ascertain the S-CSCF. Routing SIP requests arriving from other SIP networks is also a responsibility of the I-CSCF. The I-CSCF queries the HSS in order to discover the S-CSCF, which is assigned to a particular subscriber, or select a new S-CSCF based on configured capabilities.

[0039] A Breakout Gateway Control Function (BGCF) implemented by a server is an IMS element that chooses the network where PSTN breakout happens, in case when call is placed by a user from wirelessly communicating device to wired device. If the breakout is to occur in the same network as the BGCF, then the BGCF selects a MGCF (Media Gateway Control Function) which will be responsible for the interworking with the PSTN.

[0040] The S-CSCF, I-CSCF and BGCF are collectively being referred to as SIB node server. It is noted that a SIB node server may be a single server or plurality of servers connected to a network. [0041] As discussed in the background section, there is no way prescribed in the art for extracting only desired SIP packets at SIB node server [108],

[0042] The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by a method and a system for extracting desired set of one or more SIP packets at SIB node server [108],

[0043] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0056] Application Function (AF) [126a] is a network function that represents external applications interfacing with the 5G core network to access network capabilities and services.

[0057] User Plane Function (UPF) [128u] is a network function responsible for handling user data traffic, including packet routing, forwarding, and QoS enforcement.

[0058] Data Network (DN) [130d] refers to a network that provides data services to user equipment (UE) in a telecommunications system. The data services may include but are not limited to Internet services, private data network related services.

[0059] In an implementation of the disclosure in Figure IB, an exemplary block diagram of a system [100] for extracting desired set of one or more Session Initiation Protocol (SIP) packets at a System Information Block (SIB) node server [108] is shown, in accordance with the exemplary embodiments of the present disclosure. The system [100] comprises a user equipment (UE) [107], a file manager unit [ 110], a SIB node server [108] and a debugging unit [112], The SIB node server [108] of the system [100] comprises an extraction unit [102], a matching unit [104] and a database [106], It is to be noted that the user equipment UE [107] can be a processing unit. It is also to be noted that processing unit may partly reside in the user equipment, or the processing unit can operate distinctly from the user equipment in the network. It is further noted that the UE [107] can interact with the system [100] and can therefore reside outside of the system [100], Also, all of the components/ units of the system [100] are assumed to be connected to each other unless otherwise indicated below. Also, in Fig. IB only a few units are shown, however, the system [100] may comprise multiple such units or the system [100] may comprise any such numbers of said units, as required to implement the features of the present disclosure. Further, in an implementation, the system [100] may reside in a server or a network entity. In yet another implementation, the system [100] may reside partly in the server/ network entity and partly in the user device.

[0060] Further, in accordance with the present disclosure, it is to be acknowledged that the functionality described for the various the components/units can be implemented interchangeably. While specific embodiments may disclose a particular functionality of these units for clarity, it is recognized that various configurations and combinations thereof are within the scope of the disclosure. The functionality of specific units as disclosed in the disclosure should not be construed as limiting the scope of the present disclosure. Consequently, alternative arrangements and substitutions of units, provided they achieve the intended functionality described herein, are considered to be encompassed within the scope of the present disclosure.

[0061] Further, the file manager unit [110] and the database [106] refers to a machine or computer- readable medium including any mechanism for storing information in a form readable by a computer or similar machine. 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. Also, the storage unit is configured to store a data that is required by one or more units of the system [100] to perform their respective operations.

[0062] Additionally, the extraction unit [102], the matching unit [104], and the debugging unit [112] are processors. The processor may be a general-purpose processor, a special purpose processor, a conventional processor, a digital signal processor, a plurality of microprocessors, one or more microprocessors in association with a DSP core, a controller, a microcontroller, Application Specific Integrated Circuits, Field Programmable Gate Array circuits, any other type of integrated circuits, etc.

[0063] The system [100] is configured for extracting only desired SIP packets at SIB node server [108], with the help of the interconnection between the components/units of the system [100] .

[0064] The extraction unit [102] is configured to retrieve a configuration file and a first set of one or more SIP packets, wherein the configuration file relates to a predefined set of one or more SIP packets. The configuration file is created by the file manager unit [110] of the system [100] upon receiving a command via a command line interface. The extraction unit [102] is further configured to extract a first set of data from the first set of one or more SIP packets and a second set of data from the configuration file. It is further important to note that the first set of one or more SIP packets includes the one or more SIP packets received at the SIB node server [108], and the second set of one or more SIP packets includes one or more SIP packets stored in the configuration file. The first set of data comprises at least a set of subscriber details, and the second set of data comprises at least a set of header details. For instance, the SIB node server [108] uses the configuration file (in an XML format having i.e., “.xml” extension) for subscriber’s tracing where subscriber’s detail(s) such as A-party number, B-party number, location, device name etc. received by SIB node server [108] in the form of SIP packets (each packet having multiple headers). The headers details contained in configuration file are one or more of those which are present in the SIP packets as prescribed by standard. It is also emphasized that one or more of logical operators like AND, OR, REGULAR, and the like can be applied to headers made part of configuration file. Also, the multiple headers can be added in logical permutation combination (AND or OR operator or REGULAR expression). The meaning of AND, OR, REGULAR, and the like is same as what is known to a person ordinarily skilled in the art and these are to be construed in broadest sense possible without limiting the scope of the present disclosure.

[0065] The matching unit [104] is configured to match the first set of data with the second set of data. Based upon the same, the matching unit [104] generates a match result based on the matching. The match result is one of a match-success result and a match-fail result. The match-success result is generated in an event the first set of data matches the second set of data while the match-fail result is generated in an event the first set of data does not match the second set of data. For instance, in an exemplary scenario, subscriber’s detail(s) is matched with information in the configuration file which was fed to the SIB node server [108] through the command line interface.

[0066] The database [106] is responsible for storing the desired set from the set of one or more SIP packets. It is important to note that the desired set comprises one or more SIP packets from the first set of one or more SIP packets for which the match-success result is generated by the matching unit [104], The debugging unit [112] of the system [100] is configured to perform a debug operation on the desired set from the one or more SIP packets.

[0067] In yet another implementation of the disclosure, a non-transitory computer readable storage medium for extracting a desired set of one or more session initiation protocol (SIP) packets at a system information block (SIB) node server [108], The instructions when executed by one or more units of a system [100] configured for extracting the desired set of one or more SIP packets at the SIB node server [108], cause an extraction unit [102] to retrieve a configuration file, a first set of one or more SIP packets and a configuration file related to a pre-defined set of one or more SIP packets. The instructions upon retrieval further cause the extraction unit [102] to extract a first set of data from the first set of one or more SIP packets and a second set of data from the configuration file. The instructions upon extraction further cause a matching unit [104] to match the first set of data with the second set of data from the configuration file. The instructions upon matching further cause the matching unit [104] to generate a match result based on the matching. It is to be noted that the match result is one of a match-success result and a match-fail result. It is further noted that the match-success result is generated in an event the first set of data matches the second set of data while the match-fail result is generated in an event the first set of data does not match the second set of data. The instructions upon generation further cause a database [106] to store the desired set from the set of one or more SIP packets. It is to be noted that the desired set comprises one or more SIP packets from the first set of one or more SIP packets for which the match-success result is generated.

[0068] In an implementation of the disclosure in Figure 2, an exemplary method flow diagram [200], for extracting desired set of one or more session initiation protocol (SIP) packets at a system information block (SIB) node server [108], in accordance with exemplary embodiments of the present disclosure is shown. In an implementation the method [200] is performed by the system [100], As shown in Figure 2, the method [200] starts at step [202],

[0069] At step [204], the method [200] as disclosed by the present disclosure comprises retrieving a first set of one or more SIP packets and a configuration file by an extraction unit [102] at the system information block (SIB) node server [108], It is to be noted that the configuration file relates to a second set of one or more SIP packets.

[0070] In an implementation of the present disclosure, the first set of one or more SIP packets including the one or more SIP packets is received at the SIB node server [108], and the second set of one or more SIP packets including one or more SIP packets stored in the configuration file.

[0071] In an implementation of the present disclosure, the configuration file is created by a file manager unit [110] upon receiving a command via a command line interface in response to a complaint received by a network operator. Thus, when one or more errors occur, a configuration file is created storing the header details of the erroneous SIP packets.

[0072] Next, at step [206], the method [200] as disclosed by the present disclosure comprises extracting a first set of data from the first set of one or more SIP packets and a second set of data from the configuration file by the extraction unit [102] at the SIB node server [108],

[0073] In an implementation of the disclosure, the first set of data comprises at least a set of subscriber details while the second set of data comprises at least a set of header details.

[0074] Next, at step [208], the method [200] as disclosed by the present disclosure comprises matching the first set of data with the second set of data from the configuration file by a matching unit [104] at the SIB node server [108], For e.g., the first set of data, i.e. the subscriber’s call detail(s) such as but not limited to A-party number (calling party), B-party number (receiving party), location, device name) is matched with the second set of data, i.e., header details in the configuration file (.xml).

[0075] Next, at step [210], the method [200] as disclosed by the present disclosure comprises generating a match result based on the matching by the matching unit [104] at the SIB node server [108], It is to be noted that the match result is one of a match-success result and a match-fail result. It is further noted that the match-success result is generated in an event the first set of data matches the second set of data while the match-fail result is generated in an event the first set of data does not match the second set of data. In the above example, if the subscriber details such as the A party number and the B party number are the same as those stored in the header details in the configuration file, then the match-success result is generated. If the subscriber details do not match with the header details in the configuration file, then the match-fail result is generated.

[0076] Next, at step [212], the method [200] as disclosed by the present disclosure comprises storing the desired set from the set of one or more SIP packets in a database [106] at the SIB node server [108], It is further noted that the desired set comprises one or more SIP packets from the first set of one or more SIP packets for which the match-success result is generated by the matching unit [104], Thus, the entire first set of SIP packets received at the SIB node server are not stored as per the implementation of the present disclosure. Instead, more advantageously, the present disclosure encompasses storing only the desired set of SIP packets from the first set of SIP packets, i.e., storing only those SIP packets that match the header of the SIP packets in the configuration file.

[0077] In an implementation of the present disclosure, a debugging unit [112] performs a debug operation on the desired set from the set of one or more SIP packets.

[0078] Thereafter, the method terminates at step [214],

[0079] Referring to Fig. 3, an exemplary scenario indicating the process [300] for extracting desired set of one or more session initiation (SIP) packets at a system information block (SIB) node server [108] is shown, in accordance with exemplary embodiments of the present disclosure. When one or more users raise a complaint with a network operator, the network operator prepares/configures/creates a configuration file through command line interface at the SIB node server [108], This can be seen at [Step 1] where the SIB node server [108] extracts the subscriber details from SIP packets and header details from the configuration file (.xml). Then, after preparation/configuration/creation of the configuration file, the SIB node server [108] compares an input SIP packet with the information/data present in the configuration file. This can be seen at [Step 2] when the SIB node server [108] matches the subscriber's details with header details in the configuration file. If input SIP packet matches with the information/data present in the configuration file, the SIB node server [108] is configured to store the SIP packet in a database [106] connected to or part of SIB node server [108], else the SIP packet is not stored in the database [106], This can be seen at [Step 3], Thereon, the SIB node server [108] will capture the SIP packet for further debugging.
