METHOD AND SYSTEM FOR MANAGING COMMUNICATIONS IN A TELECOMMUNICATIONS NETWORK
TECHNICAL FIELD
5
[001] Embodiments of the present disclosure generally relate to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for managing communications in a telecommunications network by flexible implementation of one or more nodes in order to enhance the overall call-handling capacity. 10
BACKGROUND
[002] 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 15 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.
[003] Wireless communication technology has rapidly evolved over the past few decades,
20 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,
25 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
30 advanced, sophisticated, and capable of delivering more services to its users.
[004] In existing network arrangement, a Serving Call Session Control Function (S-CSCF), an Interrogative Call Session Control Function (I-CSCF) and a Breakout Gateway Control Function (BGCF) are independently implemented on plurality of servers of a
2

telecommunications network. Since the S-CSCF, the I-CSCF and the BGCF are independently implemented, the operation cost as well as the maintenance cost is very high. Moreover, for communication between each of the aforementioned functional node, a stack (for encoding and decoding messages transmitted between any two functional node of the telecommunications 5 network) would be needed for encoding and decoding Session Initiation Protocol (SIP) messages going through said nodes. This would further increase computational effort, latency and resources required in the telecommunications network. Further, since encoding and decoding has to happen between the S-CSCF, the I-CSCF and the BGCF, the capacity of the telecommunications network implementing these functions is reduced. As a result of the 10 reduced capacity of said nodes, multi-circle support is not possible. This further increases the hardware cost of the network. Furthermore, it is a laborious, complex, and time-consuming process to deploy multiple individual functions i.e. the S-CSCF, the I-CSCF and the BGCF.
[005] Thus, there exists an imperative need in the art to efficiently implement S-CSCF, I-15 CSCF, BGCF or similar on the telecommunications networks, which the present disclosure aims to address.

For example, a computer-readable medium includes read-only memory (“ROM”), random access memory (“RAM”), magnetic disk storage media, optical 5 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.
[036] As used herein “interface” or “user interface refers to a shared boundary across which 10 two or more separate components of a system exchange information or data. The interface may also be referred to a set of rules or protocols that define communication or interaction of one or more modules or one or more units with each other, which also includes the methods, functions, or procedures that may be called.
15 [037] All modules, units, components used herein, unless explicitly excluded herein, may be software modules or hardware processors, the processors being a general-purpose processor, a special purpose processor, a conventional processor, a digital signal processor (DSP), a plurality of microprocessors, one or more microprocessors in association with a DSP core, a controller, a microcontroller, Application Specific Integrated Circuits (ASIC), Field
20 Programmable Gate Array circuits (FPGA), any other type of integrated circuits, etc.
[038] As used herein “Radio Access Technology (RAT)” refers to the technology used by mobile devices/ user equipment (UE) to connect to a cellular network i.e., a telecommunications network. It refers to the specific protocol and standards that govern the
25 way devices communicate with base stations of the telecommunications network, which are responsible for providing the wireless connection in the telecommunications network. 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),
30 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.
[039] Further, a Serving Call Session Control Function (S-CSCF) is the primary node 5 implemented by a server of in the telecommunications network, in an IP Multimedia Subsystem (IMS) responsible for session control. Subscribers will be allocated the S-CSCF for the duration of their IMS registration in order to facilitate routing of a Session Initiation Protocol (SIP) packets as part of service establishment procedures. Consequently, the S-CSCF downloads a subscriber profile from the HSS (Home Subscriber Server) at the time of 10 registration, which allows the S-CSCF to ascertain a relevant Application Server (AS) for a service request.
[040] Further, an Interrogating Call Session Control Function (I-CSCF) implemented by a server of the telecommunications network and is responsible for onward routing of the SIP
15 packets to the appropriate S-CSCF for a given subscriber associated with the subscriber profile. This routing capability is utilized in specific scenarios only, such as during registration in order to assign or ascertain the S-CSCF. Routing the 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
20 configured capabilities.
[041] Furthermore, a Breakout Gateway Control Function (BGCF) implemented by a server of the telecommunications network and is an IMS element that chooses the network where a Public Switch Telephone Network (PSTN) breakout happens, in case when call is placed by 25 the subscriber from wirelessly communicating device to a 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.
[042] Further details about the S-CSCF, the I-CSCF and the BGCF are also described in 3GPP 30 standards and the same are being incorporated herein by way of reference and is not being repeated hereinafter for sake of brevity.
[043] As discussed in the background section, the current known solutions have several shortcomings such as high operation cost, high maintenance cost, reduced capacity due to
10

encoding and decoding required for inter-function communication, lack of multi-circle support, complex and laborious deployment of individual functions etc. The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by providing method and system of managing communications in the telecommunications 5 network, which provides a combination of one or more nodes in a single unit for enhancing an efficiency and an effectiveness of the telecommunication network by reducing the time consumed while implementation of multiple nodes, and thereby improving communication flow.

15 may also implement a method for managing communications in a telecommunications network utilising the system. In another implementation, the computing device [1000] itself implements the method for managing communications in the telecommunications network using one or more units configured within the computing device [1000], wherein said one or more units are capable of implementing the features as disclosed in the present disclosure.
20
[060] The computing device [1000] may include a bus [1002] or other communication mechanism for communicating information, and a hardware processor [1004] coupled with the bus [1002] for processing information. The hardware processor [1004] may be, for example, a general-purpose microprocessor. The computing device [1000] may also include a main
25 memory [1006], such as a random-access memory (RAM), or other dynamic storage device, coupled to the bus [1002] for storing information and instructions to be executed by the processor [1004]. The main memory [1006] also may be used for storing temporary variables or other intermediate information during execution of the instructions to be executed by the processor [1004]. Such instructions, when stored in non-transitory storage media accessible to
30 the processor [1004], render the computing device [1000] into a special-purpose machine that is customized to perform the operations specified in the instructions. The computing device [1000] further includes a read only memory (ROM) [1008] or other static storage device coupled to the bus [1002] for storing static information and instructions for the processor [1004].

[061] A storage device [1010], such as a magnetic disk, optical disk, or solid-state drive is provided and coupled to the bus [1002] for storing information and instructions. The computing device [1000] may be coupled via the bus [1002] to a display [1012], such as a cathode ray 5 tube (CRT), Liquid crystal Display (LCD), Light Emitting Diode (LED) display, Organic LED (OLED) display, etc. for displaying information to a computer user. An input device [1014], including alphanumeric and other keys, touch screen input means, etc. may be coupled to the bus [1002] for communicating information and command selections to the processor [1004]. Another type of user input device may be a cursor control [1016], such as a mouse, a trackball, 10 or cursor direction keys, for communicating direction information and command selections to the processor [1004], and for controlling cursor movement on the display [1012]. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allow the device to specify positions in a plane.

According to one implementation, the techniques herein are performed by the computing device [1000] in response to the processor
20 [1004] executing one or more sequences of one or more instructions contained in the main memory [1006]. Such instructions may be read into the main memory [1006] from another storage medium, such as the storage device [1010]. Execution of the sequences of instructions contained in the main memory [1006] causes the processor [1004] to perform the process steps described herein. In alternative implementations of the present disclosure, hard-wired circuitry
25 may be used in place of or in combination with software instructions.
[063] The computing device [1000] also may include a communication interface [1018] coupled to the bus [1002]. The communication interface [1018] provides a two-way data communication coupling to a network link [1020] that is connected to a local network [1022]. 30 For example, the communication interface [1018] may be an integrated services digital network (ISDN) card, cable modem, satellite modem, or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, the communication interface [1018] may be a local area network (LAN) card to provide a data communication connection to a compatible LAN. Wireless links may also be implemented. In any such
14

implementation, the communication interface [1018] sends and receives electrical, electromagnetic, or optical signals that carry digital data streams representing various types of information.
5 [064] The computing device [1000] can send messages and receive data, including program code, through the network(s), the network link [1020] and the communication interface [1018]. In the Internet example, a server [1030] might transmit a requested code for an application program through the Internet [1028], the ISP [1026], the host [1024], the local network [1022] and the communication interface [1018]. The received code may be executed by the processor 10 [1004] as it is received, and/or stored in the storage device [1010], or other non-volatile storage for later execution.
[065] Referring to Figure 3, an exemplary block diagram of a system [300] for managing communications in a telecommunications network, is shown, in accordance with the exemplary
15 implementations of the present disclosure. The system [300] comprises at least one system information block (SIB) node [302]. Further, the SIB node [302] of the system further comprises at least one receiving unit [306], at least one determining unit [308], at least one selecting unit [310], at least one processing unit [312]. Also, all of the components/ units of the system [300] are assumed to be connected to each other unless otherwise indicated below. As
20 shown in the figures all units shown within the system [300] should also be assumed to be connected to each other. Also, in Figure 3 only a few units are shown, however, the system [300] may comprise multiple such units or the system [300] may comprise any such numbers of said units, as required to implement the features of the present disclosure. In another implementation, the system [300] may reside in a server or a network entity. In yet another
25 implementation, the system [300] may reside partly in the server and/or the network entity.
[066] The system [300] is configured for managing the communications in the telecommunications network, with the help of the interconnection between the components/units of the system [300]. In order to managing the communications in the 30 telecommunications network, the receiving unit [306] is configured to receive a Session Initiation Protocol (SIP) message for a communication request, wherein the SIB node [302] is an integration of one or more nodes [304]. Further, the one or more nodes [304] comprises a serving call session function (S-CSCF), an interrogative call session control function (I-CSCF), and a breakout gateway control function (BGCF).
15

[067] Further, the SIB node [302] as disclosed herein is primarily designed to provide communication sessions, which includes voice call sessions and/or video conference sessions over an Internet Protocol (IP) networks and the SIB node [302] is operated within a service 5 provider of the telecommunications network. Herein, the SIB node [302] may incorporates the receiving unit [306] for accepting the SIP message for the communication request from a user of the telecommunications network.
[068] It is to be noted that the SIP message is used to facilitate, continue, or dismiss 10 communication sessions between two or more end users over the IP networks. Some common SIP message may include an invite message, a bye message, a register message, and alike messages that be obvious to the person skilled in the art.
[069] The one or more nodes [304] that may be integrated within the SIB node [302] are the 15 S-CSCF, the I-CSCF and the BGCF. The integration of one or more nodes [304] allows the SIB node [302] to perform as a single unit. Additionally, while the one or more nodes [304] outlined herein may include the S-CSCF, the I-CSCF, and the BGCF, it should be noted that this does not be interpreted in any manner to restrict the scope of this disclosure. The SIB node [302] may include any other node that may be obvious to the person skilled in the art for 20 implementing the solution as disclosed herein.
[070] The S-CSCF is responsible for managing the sessions of end-users in the telecommunications network. The S-CSCF handles a registration request of the end-users and further facilitates, maintains, or dismiss sessions between one or more end-users. Upon 25 receiving the SIP message from the receiving unit [306], the S-CSCF performs multiple session control functions such as an authentication function, an authorization function, and a routing function based on the receipt of the SIP message.
[071] For example, when the end user desires to initiate a voice call, the S-CSCF processes
30 the SIP message from the end-user and sets up the voice call based performing one or more of
the authentication function, the authorization function, and the routing function by the S-CSCF.
[072] Further, the I-CSCF functions as an intermediary between the S-CSCF and the end-user. The I-CSCF interacts with a home subscriber server (HSS) to determine the appropriate
16

S-CSCF for the end-user and then forwards the SIP message to the appropriate S-CSCF. The I-CSCF ensures that the communication request reaches the correct destination i.e., the appropriate S-CSCF.
5 [073] Further, the BGCF facilitates the exchange of the SIP message between different networks or different service providers by routing a communication session associated with the SIP message to the appropriate network node.
[074] In an exemplary embodiment, when a user i.e., the end-user initiates a call, the SIP 10 message is received by the SIB node [302]. The I-CSCF in the SIB node [302] queries the HSS to find the appropriate S-CSCF. Once the appropriate S-CSCF is determined, the SIP message is forwarded to that appropriate S-CSCF. If the call is to a number outside the IP network of the user, the BGCF routes the communication session, that is associated with the SIP message to the appropriate network mode. 15
[075] Further, the determining unit [308] is connected at least with the receiving unit [306], wherein the determining unit [308] is configured to determine a type of the communication request based on the received SIP message.
20 [076] Post receiving the SIP message from the receiving unit [306], the determining unit [308] examines the received SIP message. It is to be noted that the SIP message may contains information of the user (such as an address information, a session details information, a session management information, etc.). Further, the determining unit [308] utilizes the information for identifying the type of communication request, that is required by the user. For example, the
25 SIP message clarifies that whether the user request for a voice call, a video conference, or some other type of communication session.
[077] Further, the selecting unit [310] is connected at least with the determining unit [308], wherein the selecting unit [310] is configured to select at least one node from the one or more 30 nodes [304] based on the determined type of the communication request.
[078] Once, the type of communication request is determined by the determining unit [308], then in accordance with the present solution as disclosed herein the selecting unit [310] may select at least one node form the one or more nodes [304] i.e., the S-CSCF, the I-CSCF and the
17

BGCF. In an implementation of the present disclosure, the selecting unit [310] may select a most appropriate node or a combination of nodes from the one or more nodes [304] i.e., the S-CSCF, the I-CSCF and the BGCF to optimize the use of the telecommunications network.
5 [079] For example, in a scenario the determining unit [308] identifies the communication request to be a voice call from the end user of the telecommunications network, in that scenario the selecting unit [310] may select the Serving Call Session Function (S-CSCF) to handle the request. Further, in an event, if the request is a voice call request for a user outside an IP network of the end user, the Breakout Gateway Control Function (BGCF) might be selected by 10 the selecting unit [310] to route the voice call associated with the end user.
[080] Furthermore, the processing unit [312] is connected at least with the selecting unit [310], wherein the processing unit [312] is configured to process the communication request at the selected at least one node. In addition, the processing unit [312] may facilitates a stack-less
15 SIP communication between the one or more nodes [304] by facilitating communication between the one or more nodes [304] i.e., the S-CSCF, the I-CSCF and the BGCF directly based on a pre-determined routing logic and independent of any protocol stack an. Further, the stack-less SIP communication corresponds to absence of a stack of protocols utilised by the telecommunications network for at least one of an encoding of the SIP message and a decoding
20 of the SIP message. Further, the processing of the communication request at the selected at least one node is performed without parsing the SIP message, as the processing the communication request involves utilizing the pre-determined routing logic, wherein the pre¬determined routing logic is further based on the type of the communication request and a subscriber data.
25
[081] It is to be noted that in the telecommunication network, the encoding of the SIP message means converting the information in the communication request at the selected at least one node into a specific format that can be sent over the telecommunication network in order to provide communication between the one or more nodes [304] by facilitating communication
30 between the one or more nodes [304] i.e., the S-CSCF, the I-CSCF and the BGCF.
[082] It is to be noted that in the telecommunication network, the decoding of the SIP message, on the other hand, is the opposite process. The decoding of the SIP message involves translating the encoded SIP message back into a readable format for humans and/or computers
18

can understand in order to allow the recipient i.e., the humans and/or the computers to interpret the message and take appropriate actions based on the translated message in the readable format.
5 [083] It is to be noted that in traditional network architectures, the stack of protocols utilised by the telecommunications network may include but not limited to a Session Initiation Protocol (SIP), a Simple Mail Transfer Protocol (SMTP), a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), an Internet Protocol (IP), and similar known in the art.
10 [084] However, in present case at the SIB node [302], these stacks of protocols are not used in order to simplify the communication process and improve efficiency of the telecommunications network.
[085] Further, the processing of the communication request at the selected node or a 15 combination of the nodes from the one or more nodes [304] is performed without parsing the SIP message. It is to be noted that parsing is the process of analysing a string of symbols according to the rules of a formal code. In this case, the parsing may refer to analyse the SIP message to extract information associated with the communication request. However, in accordance with the present solution as disclosed herein, the parsing process of the SIP message 20 is bypassed by the SIB node [302] for simplifying the communication process in the telecommunications network.
[086] For example, in case the user initiates a voice call request, then call is received at the SIB node [302] as the SIP message. Further, the SIP message are bypassed by the SIB node 25 [302] to a node based on determining the type of communication as the voice call request without any parsing, thereby allowing the solution as disclosed herein to quickly route the voice call request, for ensuring efficient establishment of voice call associated with the voice call request.
30 [087] To be noted, that the processing unit [312] routes the request based on predefined criteria, such as an availability criteria of the selected node and a call priority criteria etc. for ensuring the call establishment without going through the parsing.

[088] Further, the processing of the communication request involves utilizing a pre¬determined routing logic based on the type of the communication request and a subscriber data. The routing logic referred here, determines how the communication request is handled in the telecommunications network and the node or combination of nodes from the one or more nodes 5 [304] is/are selected to process the communication request.
[089] For example, in a scenario if the communication request is for a voice call, the routing logic might suggest that the request is to be handled by the S-CSCF. Further, in another scenario if the request is to voice call a number outside the IP network, the BGCF might be selected to 10 route the call.
[090] Referring to Figure 4, an exemplary method flow diagram [400] for managing communications in a telecommunications network, in accordance with exemplary implementations of the present disclosure is shown. In an implementation the method [400] is 15 performed by the system [300]. Further, in an implementation, the system [300] may be present in a server device to implement the features of the present disclosure. Also, as shown in Figure 4, the method [400] starts at step [402].
[091] At step [404], the method [400] comprise receiving, by a receiving unit [306] at a 20 system information block (SIB) node [302], a Session Initiation Protocol (SIP) message for a communication request, wherein the SIB node [302] is an integration of one or more nodes [304]. Further as disclosed herein by the present disclosure, the one or more nodes [304] comprises a serving call session function (S-CSCF), an interrogative call session control function (I-CSCF), and a breakout gateway control function (BGCF). 25
[092] The method [400] may be performed within the SIB node [302]. The SIB node [302] facilitates communication sessions, which includes voice call sessions and/or video conference sessions over an Internet Protocol (IP) networks and the SIB node [302] is operated within a service provider of the telecommunications network. Herein, the SIB node [302] may 30 incorporates the receiving unit [306] for accepting the SIP message for the communication request from a user of the telecommunications network.
[093] It is to be noted that the SIP message is used to facilitate, continue, or dismiss communication sessions between two or more end users over the IP networks. Some common
20

SIP message may include an invite message, a bye message, a register message, and alike messages that be obvious to the person skilled in the art.
[094] The one or more nodes [304] that may be integrated within the SIB node [302] are the 5 S-CSCF, the I-CSCF and the BGCF. The integration of one or more nodes [304] allows the SIB node [302] to perform as a single unit. Additionally, while the one or more nodes [304] outlined herein may include the S-CSCF, the I-CSCF, and the BGCF, it should be noted that this does not be interpreted in any manner to restrict the scope of this disclosure. The SIB node [302] may include any other node that may be obvious to the person skilled in the art for 10 implementing the solution as disclosed herein.
[095] The S-CSCF is responsible for managing the sessions of end-users in the telecommunications network. The S-CSCF handles a registration request of the end-users and further facilitates, maintains, or dismiss sessions between one or more end-users. Upon 15 receiving the SIP message from the receiving unit [306], the S-CSCF performs multiple session control functions such as an authentication function, an authorization function, and a routing function based on the receipt of the SIP message.
[096] For example, when the end user desires to initiate a voice call, the S-CSCF processes
20 the SIP message from the end-user and sets up the voice call based performing one or more of
the authentication function, the authorization function, and the routing function by the S-CSCF.
[097] Further, the I-CSCF functions as an intermediary between the S-CSCF and the end-user. The I-CSCF interacts with a home subscriber server (HSS) to determine the appropriate 25 S-CSCF for the end-user and then forwards the SIP message to the appropriate S-CSCF. The I-CSCF ensures that the communication request reaches the correct destination i.e., the appropriate S-CSCF.
[098] Further, the BGCF facilitates the exchange of the SIP message between different 30 networks or different service providers by routing a communication session associated with the SIP message to the appropriate network node.
[099] In an exemplary embodiment, when a user i.e., the end-user initiates a call, the SIP message is received by the SIB node [302]. The I-CSCF in the SIB node [302] queries the HSS
21

to find the appropriate S-CSCF. Once the appropriate S-CSCF is determined, the SIP message is forwarded to that appropriate S-CSCF. If the call is to a number outside the IP network of the user, the BGCF routes the communication session, that is associated with the SIP message to the appropriate network mode. 5
[100] The method [400] further at step [406] comprises determining, by a determining unit [308] at the SIB node [302], a type of the communication request based on the received SIP message.
10 [101] As disclosed by the present disclosure, the method [400] post receiving the SIP message from the receiving unit [306], the determining unit [308] examines the received SIP message. It is to be noted that the SIP message may contains information of the user (such as an address information, a session details information, a session management information, etc.). Further, the determining unit [308] utilizes the information for identifying the type of communication
15 request, that is required by the user. For example, the SIP message clarifies that whether the user request for a voice call, a video conference, or some other type of communication session.
[102] For example, if the SIP message includes a request for a video communication, the determining unit [308] then identifies the communication request as a video call. Conversely, 20 if the SIP message includes a request for an audio communication, the determining unit [308] would identify the communication request as a voice call.
[103] The method [400] at step [408] further comprises selecting, by a selecting unit [310] at the SIB node [302], at least one node from the one or more nodes [304] based on the determined 25 type of the communication request.
[104] Further, after the type of communication request is determined by the determining unit [308], the method [400] then in accordance with the present solution as disclosed herein comprise that the selecting unit [310] may select at least one node form the one or more nodes 30 [304] i.e., the S-CSCF, the I-CSCF and the BGCF. In an implementation of the present disclosure, the selecting unit [310] may select a most appropriate node or a combination of nodes from the one or more nodes [304] i.e., the S-CSCF, the I-CSCF and the BGCF to optimize the use of the telecommunications network.

[105] For example, in a scenario the determining unit [308] identifies the communication request to be a voice call from the end user of the telecommunications network, in that scenario the selecting unit [310] may select the Serving Call Session Function (S-CSCF) to handle the request. Further, in an event, if the request is a voice call request for a user outside an IP 5 network of the end user, the Breakout Gateway Control Function (BGCF) might be selected by the selecting unit [310] to route the voice call associated with the end user.
[106] The method [400] further at step [410] comprises processing, by a processing unit [312] at the SIB node [302], the communication request at the selected at least one node. Further, in
10 an implementation of the present disclosure as disclosed herein the processing the communication request is performed without parsing the SIP message. Further, the processing the communication request involves utilizing a pre-determined routing logic based on the type of the communication request and a subscriber data. Furthermore, the processing unit [312] facilitates a stack-less SIP communication between the one or more nodes [304], the S-CSCF,
15 the I-CSCF and the BGCF directly based on a pre-determined routing logic and independent of any protocol stack an. Further, the stack-less SIP communication corresponds to absence of a stack of protocols utilised by the telecommunications network for at least one of an encoding of the SIP message and a decoding of the SIP message. Further, the processing of the communication request at the selected at least one node is performed without parsing the SIP
20 message, as the processing the communication request involves utilizing the pre-determined routing logic, wherein the pre-determined routing logic is further based on the type of the communication request and a subscriber data.
[107] It is to be noted that in traditional network architectures, the stack of protocols utilised 25 by the telecommunications network may include but not limited to a Session Initiation Protocol (SIP), a Simple Mail Transfer Protocol (SMTP), a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), an Internet Protocol (IP), and similar known in the art.
[108] However, in present case at the SIB node [302], these stacks of protocols are not used 30 in order to simplify the communication process and improve efficiency of the telecommunications network.
[109] Further, the processing of the communication request at the selected node or a combination of the nodes from the one or more nodes [304] is performed without parsing the
23

SIP message. It is to be noted that parsing is the process of analysing a string of symbols according to the rules of a formal code. In this case, the parsing may refer to analyse the SIP message to extract information associated with the communication request. However, in accordance with the present solution as disclosed herein, the parsing process of the SIP message 5 is bypassed by the SIB node [302] for simplifying the communication process in the telecommunications network.
[110] For example, in case the user initiates a voice call request, then call is received at the SIB node [302] as the SIP message. Further, the SIP message are bypassed by the SIB node 10 [302] to a node based on determining the type of communication as the voice call request without any parsing, thereby allowing the solution as disclosed herein to quickly route the voice call request, for ensuring efficient establishment of voice call associated with the voice call request.
15 [111] To be noted, that the processing unit [312] routes the request based on predefined criteria, such as an availability criteria of the selected node and a call priority criteria etc. for ensuring the call establishment without going through the parsing.
[112] Further, the processing of the communication request involves utilizing a pre¬determined routing logic based on the type of the communication request and a subscriber data.
20 The routing logic referred here, determines how the communication request is handled in the telecommunications network and the node or combination of nodes from the one or more nodes [304] is/are selected to process the communication request.
[113] For example, in a scenario if the communication request is for a voice call, the routing 25 logic might suggest that the request is to be handled by the S-CSCF. Further, in another scenario if the request is to voice call a number outside the IP network, the BGCF might be selected to route the call.
[114] The method [400] terminates at step 412. 30
[115] The present disclosure further discloses a non-transitory computer readable storage medium storing instructions for managing communications in a telecommunications network, the instructions including executable code, the executable code when executed, may cause: a receiving unit [306] of a system information block (SIB) node [302] to receive a Session
24

Initiation Protocol (SIP) message for a communication request, wherein the SIB node [302] is an integration of one or more nodes [304], a determining unit [308] of the SIB node [302] to determine a type of the communication request based on the received SIP message, a selecting unit [310] of the SIB node [302] to select at least one node from the one or more nodes [304] 5 based on the determined type of the communication request, and a processing unit [312] of the SIB node [302] to process the communication request at the selected at least one node.
The present disclosure further discloses a user equipment (UE) comprising a processor connected to at least a transceiver unit, wherein the UE is configured to: transmit, by the
10 transceiver unit, a communication request to a system, wherein the system further comprises: a receiving unit [306] configured to receive a Session Initiation Protocol (SIP) message for the communication request, wherein the SIB node [302] is an integration of one or more nodes [304], a determining unit [308] configured to determine a type of the communication request based on the received SIP message, a selecting unit [310] configured to select at least one node
15 from the one or more nodes [304] based on the determined type of the communication request, and a processing unit [312] configured to process the communication request at the selected at least one node; and receive, by the transceiver unit, a response associated with the communication request from the system. [116] As is evident from the above, the present disclosure provides a technically advanced
20 solution for managing communications in a telecommunications network. The present solution discloses combining the functionalities of a plurality of network nodes in the telecommunications network into a single node, which is referred to as the System Information Block (SIB) node in the present disclosure. The SIB node as disclosed in the present disclosure provides better network utilization as computational effort, latency, and resource consumption
25 are considerably reduced in comparison to the existing solution. Further, the present solution discloses a technically advanced solution by disclosing the SIB node with improved capacity for multiple network nodes as compared to a separate implementation for each network node. Further, the present solution provides the technically advanced solution by eliminating the use of stacked protocols in communication between the multiple network nodes, implying that a
30 time utilised by computational resources in encoding and decoding is also eliminated by implementing the present solution. Consequently, the latency of the telecommunications network is improved due to the increased capacity of the SIB node and reduced computational time. Further, the single node is capable of providing multi-circle support, which was not possible with separate implementations of multiple network nodes. It is further emphasized
25

that combining the multiple network nodes into the SIB node reduces the hardware cost, and the deployment of the single node in the telecommunications network is also simpler and easier compared to the deployment of the multiple network nodes.
5 [117] While considerable emphasis has been placed herein on the disclosed
implementations, it will be appreciated that many implementations can be made and that many changes can be made to the implementations without departing from the principles of the present disclosure. These and other changes in the implementations of the present disclosure will be apparent to those skilled in the art, whereby it is to be understood that the foregoing 10 descriptive matter to be implemented is illustrative and non-limiting.
