FIELD OF THE INVENTION
[0001] The present invention relates to the field of wireless communication systems, more particularly relates to a method and system for providing a communication service.
BACKGROUND OF THE INVENTION
[0002] The current enterprise telephone management system is a sophisticated telecommunications solution designed to handle the communication needs of businesses and organizations. It serves as the central platform for managing and facilitating voice-based communication within the enterprise, providing advanced features and functionality to improve productivity and efficiency.
[0003] Further the current enterprise telephone management system manages or control the access rights for each fixed telephone device within the telephone network. The access rights are usually pre-defined and set for each fixed telephone device. However, the drawback of the existing management system is the access rights for each fixed telephone device are fixed and cannot be changed in real-time.
[0004] Further the existing telephone networks are configured to deal with fixed telephone devices using a combination of hardware and software system. The fixed telephone device may connect with external number or extensions within the organization using conventional fiber optics of voice over internet protocol (VoIP).
[0005] Further the current enterprise telephone management system usually relies on Private Branch Exchange (PBX). The PBX is the core component responsible for call routing and handling within the organization. It connects internal extensions, manages call transfers, and facilitates other call management features. Further Unified Communications (UC) software integrates various communication channels, including voice, video, instant messaging, and collaboration tools, into a single unified platform. It enables features like presence of information, voicemail, call recording, and integration with other business applications.
[0006] However, the major drawback of the current enterprise system is dynamic handling of access rights for the fixed telephone lines, capturing real-time information. The existing system also fails to adopt wireless communication devices like, mobiles phones or communication tablets.

[0038] Operational and construction features of the system 108 will be explained in detail with respect to the following figures.
[0039] FIG. 2 is an exemplary block diagram of the system 108 for providing a communication service, according to one or more embodiments of the present invention.
[0040] As per the illustrated and preferred embodiment, the system 108 is adapted for providing the communication service in the network 106. In an embodiment, the system 108 may be a Business Telephony Application Server (BTAS). The system 108 includes one or more processors 202, a memory 204, and a database 216. The one or more processors 202 includes a transceiver 208, a determination unit 210, and a validation unit 212. The one or more processors 202, hereinafter referred to as the processor 202, may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions. However, it is to be noted that the system 108 may include multiple processors as per the requirement and without deviating from the scope of the present disclosure. Among other capabilities, the processor 202 is configured to fetch and execute computer-readable instructions stored in the memory 204.
[0041] As per the illustrated embodiment, the processor 202 is configured to fetch and execute computer-readable instructions stored in the memory 204 as the memory 204 is communicably connected to the processor 202. The memory 204 is configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to provide the communication service in the network 106. The memory 204 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as disk memory, EPROMs, FLASH memory, unalterable memory, and the like.
[0042] In an embodiment, the transceiver 208 of the processor 202 is configured to receive a dynamically initiated request from the user via one or more user equipment’s (UEs) 102 for accessing the telephonic feature. The telephonic feature includes at least one of, but not limited to, placing an international call. For e.g., if a specific extension/fixed telephony device or the user needs to make the international call in real time, and the telephonic feature has not been provided to the user or the user does not have right to access the telephonic feature, then the user can initiate the request to enable a temporary access for the telephonic feature. In an embodiment, the user requesting the telephonic feature includes at least one of the trusted user and the non-trusted user.
[0043] In an embodiment, the determination unit 210 of the processor 202 is configured to determine whether the user requesting the access to the telephonic feature is the trusted user or the non-trusted user based on a pre-approved feature list. The pre-approved feature list includes at least one of, but not limited to, one or more approved country codes for International Subscriber Dialing (ISD), blocked country codes for International Subscriber Dialing (ISD), information of the trusted user, approved Mobile Station Integrated Services Digital Network (MSISDN) for ISD, approved authentication code for ISD, and information associated with the telephonic feature. For e.g., the pre-approved feature list is a whitelist which includes data pertaining to multiple parameters of the telephonic feature.
[0044] The International Subscriber Dialing (ISD) is also known as an International Direct Dialing (IDD) which is an international telephone call that is dialed directly by a telephone subscriber or user, rather than depending on the phone operator. Each country is assigned a unique ISD code which is used to make international calls. For example, ISD code of India is +91.
[0045] The Mobile Station International Subscriber Directory Number (MSISDN) is a unique identifier assigned to each user equipment such as a mobile device in a (Global System for Mobile Communications) GSM network. An MSISDN is a phone number associated with a Subscriber Identity Module (SIM) card which is utilized to call or send a Short Messaging Service (SMS).
[0046] In order to determine whether the user requesting the access to the telephonic feature is the trusted user or the non-trusted user, the determination unit 210 checks the pre-approved feature list which includes the information of the trusted user requesting the access for the telephonic feature. In response to determining the user requesting the access to the telephonic feature is the trusted user based on the information of the trusted user included in the pre-approved feature list, the determination unit 210 enables access to the telephonic feature requested by the trusted user. In an alternate embodiment, the information of the UE 102 of the trusted user is included in the pre-approved feature list due to which the determination unit 210 enables access to the telephonic feature requested by the trusted user. The pre-approved feature list is stored in storage means such as at least one of a remote server, and the database 214 which is communicably coupled to the determination unit 210 of the one or more processors 202. Further, when the information of the user or the UE 102 of the user requesting the access to the telephonic feature is not available in the pre-approved feature list stored in the database 214 then it is determined that the user is the non-trusted user. In response to determining the user requesting the access to the telephonic feature is the non-trusted user, the determination unit 210 requests an authentication code from the non-trusted user to access the telephonic feature. The determination unit 210 of the processor 202 is further configured to retrieve the authentication code from the non-trusted user.
[0047] In an embodiment, the database 214 is configured to store the pre-approved feature list. The database 214 is one of, but not limited to, a centralized database, a cloud-based database, a commercial database, an open-source database, a distributed database, an end-user database, a graphical database, a No-Structured Query Language (NoSQL) database, an object-oriented database, a personal database, an in-memory database, a document-based database, a time series database, a wide column database, a key value database, a search database, a cache databases, and so forth. The foregoing examples of database 212 types are non-limiting and may not be mutually exclusive e.g., the database can be both commercial and cloud-based, or both relational and open-source, etc.
[0048] In an embodiment, the validation unit 212 of the processor 202 is configured to validate the authentication code retrieved by the determination unit 210 from the non-trusted user. The validation unit 212 authenticates code by parsing the pre-approved feature list as defined for the user by an admin. Further, the authentication code as defined in the pre-approved feature list is retrieved by the validation unit 212. Further the authentication code retrieved from the pre-approved feature list is compared with the authentication code retrieved from the non-trusted user to validate the authentication code retrieved from the non-trusted user. In response to the validation of the authentication code retrieved from the non-trusted user, the requested telephonic feature is enabled for accessing by the non-trusted user.
[0049] In one embodiment, the system 108 allows the admin to update the pre-approved feature list that facilitates admin to enable or disable the telephonic features in real time. In an alternate embodiment, the admin can update the pre-approved feature list via an Interactive Voice Response (IVR). For example, the admin is allowed to update/create/delete multiple parameters of the telephonic features such as updating the approved country codes for international calling which gets reflected in real-time independent of the complexity of the network.
[0050] The Interactive Voice Response (IVR) is an automated technology that allows incoming callers or users interact with a computer-operated telephone system via a voice response as well as to utilize menu options via touch tone keypad selection or speech recognition. IVR responds with pre-recorded or dynamically generated audio to further direct users on how to proceed for accessing the telephonic features.
[0051] The IVR is integrated or hosted on the system 108 or the IVR is integrated or hosted on the server 104. By integrating the IVR to the system 108, the efficiency call flow of providing the communication service to the at least one of, the trusted and the non-trusted is improved and delay pertaining to at least one of, updating the multiple parameters of the telephonic features by the admin in the system 108 and accessing the requested telephonic feature is reduced, leading to higher overall user satisfaction. The IVR is configured to render the information pertaining to the requested telephonic feature by the at least one of, the trusted and the non-trusted user to the admin.
[0052] The transceiver unit 208, the determination unit 210, and the validation unit 212, in an exemplary embodiment, are implemented as a combination of hardware and programs (for example, programmable instructions) to implement one or more functionalities of the processor 202. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 202 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processor may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 204 may store instructions that, when executed by the processing resource, implement the processor 202. In such examples, the system 108 may comprise the memory 204 storing the instructions and the processing resource to execute the instructions, or the memory 204 may be separate but accessible to the system 108 and the processing resource. In other examples, the processor 202 may be implemented by electronic circuitry.
[0053] FIG. 3 illustrates an exemplary block diagram of an architecture for the system 108 of FIG. 2, according to one or more embodiments of the present invention. More specifically, FIG. 3 illustrates the system 108 configured for providing a communication service. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the UE 102 for the purpose of description and illustration and should nowhere be construed as limiting the scope of the present disclosure.
[0054] The FIG. 3 illustrates communication between the UE 102 and the system 108. For the purpose of description of the exemplary embodiment as illustrated in FIG. 3, the User Equipment (UE) 102 uses network protocol connection to communicate with the system 108. In an embodiment, the network protocol connection is the establishment and management of communication between the UE 102 and the system 108 over the network 106 using a specific protocol or set of protocols. The network protocol connection includes, but not limited to, Session Initiation Protocol (SIP), System Information Block (SIB) protocol, Transmission Control Protocol (TCP), User Datagram Protocol (UDP), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), Simple Network Management Protocol (SNMP), Internet Control Message Protocol (ICMP), Hypertext Transfer Protocol Secure (HTTPS) and Terminal Network (TELNET).
[0055] In an embodiment, the UE 102 includes a primary processor 302, a memory 304, and a user interface 306. In alternate embodiments, the UE 102 may include more than one primary processor 302 as per the requirement of the network 106. The primary processor 302, may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions.
[0056] In an embodiment, the primary processor 302 is configured to fetch and execute computer-readable instructions stored in the memory 304. The memory 304 may be configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to request for the telephonic feature. The memory 304 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as disk memory, EPROMs, FLASH memory, unalterable memory, and the like.
[0057] In an embodiment, the user interface 306 of the UE 102 includes a variety of interfaces, for example, a graphical user interface, a web user interface, a Command Line Interface (CLI), and the like. The UE 102 transmit the request to the one or more processors 202 for accessing the telephonic feature via user interface 306.
[0058] As a working example, initially an employee of an enterprise interacts with the user interface 306 of the UE 102 for accessing at least one of the telephonic feature. Here, the employee via the UE 102 is transmitting the request to the processor 202 for accessing the telephonic feature such as an international calling service. Further, the transceiver 208 of the processor 202 receives the request from the employee. Prior to providing the international calling service to the employee requesting the international calling service, the determination unit 210 of the of the processor 202 determines whether the employee requesting the access for the international calling service is the trusted user or the non-trusted user based on the pre-approved feature list. The pre-approved feature list is updated or modified by the admin of the enterprise. The pre-approved feature list includes at least one of the one or more approved country codes for international calling service, blocked country codes for calling service, information of the trusted user, approved Mobile Station Integrated Services Digital Network (MSISDN) for international calling service, approved authentication code for international calling service, and information associated with the international calling service.
[0059] The determination unit 210 checks whether the information of the employee requesting the international calling service is available in the pre-approved feature list. For example, let us consider the admin of the enterprise has pre-stored information of some of the employees in the pre-approved feature list in order to easily avail the international calling service. The determination unit 210 identifies that the information pertaining to the employee requesting the access to the international calling service is available in the pre-approved feature list, then the determination unit 210 infers that employee as the trusted user and enables access to the international calling service. In other words, let us consider that if an employee A is requesting for accessing the international calling service and the information of the employee A is available in the pre-approved feature list, then the employee A is determined as the trusted user.
[0060] On the contrary, if the determination unit 210 identifies that the information pertaining to the employee requesting the access to the international calling service is not available in the pre-approved feature list, then the determination unit 210 infers that the employee is the non-trusted user and requests an authentication code from the employee to access the international calling service. In particular, if the employee A is requesting for accessing the international calling service and the information of the employee A is not available in the pre-approved feature list, then the employee A is determined as the non-trusted user. Thereafter, the determination unit 210 retrieves the authentication code from the employee.
[0061] Further, the authentication code retrieved from the employee is validated by the validation unit 214 by analyzing the pre-approved feature list as defined for the employees by an admin and retrieving the authentication code as defined in the pre-approved feature list. Further, the validation unit 214 compares the authentication code retrieved from the pre-approved feature list with the authentication code retrieved from the employee in order to validate the authentication code retrieved from the employee requesting for accessing the international calling service. Subsequent to validation of the authentication code, the validation unit 214 enables the employee to access the international calling service.
[0062] FIG. 4 is a flow diagram of a method 400 for providing a communication service in a network 106, according to one or more embodiments of the present invention. For the purpose of description, the method is described with the embodiments as illustrated in FIG. 2 and should nowhere be construed as limiting the scope of the present disclosure.
[0063] At step 402, the method 400 includes the step of receiving a request from a user for accessing a telephonic feature. In one embodiment, the transceiver 208 of the processor 202 is configured to receive a dynamic request from the user via the UE 102 for accessing the telephonic feature. The telephonic feature is at least one of an international calling service. For example, the dynamic request is a request from the user for enabling access to international call or enabling access to bridging service for the international call.
[0064] At step 404, the method 400 includes the step of determining whether the user requesting the access to the telephonic feature is the trusted user or the non-trusted user based on the pre-approved feature list. In one embodiment, the determination unit 210 of the processor 202 is configured to determining whether the user requesting the access to the telephonic feature is the trusted user or the non-trusted user based on the pre-approved feature list. The pre-approved feature list is stored at the database 214 which includes at least one or more approved country codes for International Subscriber Dialing (ISD), blocked country codes for International Subscriber Dialing (ISD), information of the trusted user, approved Mobile Station Integrated Services Digital Network (MSISDN) for ISD, approved authentication code for ISD, and information associated with the telephonic feature. The pre-approved feature list is updated by the admin in which the information of multiple users is pre stored by the admin. The information of multiple users which are pre stored in the pre-approved feature list are that of the trusted users. The determination unit 210 checks whether the pre-approved feature list includes the information of the user requesting the access for the telephonic feature. If the information of the user requesting access for the telephonic feature is available in the pre-approved feature list, then the determination unit 210 infers that user as the trusted user. For example, an employee of an enterprise requesting the international calling service is the trusted user when the information of that employee is prestored in the pre-approved feature list. If the information of the user requesting access for the telephonic feature is not available in the pre-approved feature list, then the determination unit 210 infers that the user as the non-trusted user.
[0065] At 406, the method 400 includes the step of in response to determining, the user requesting the access to the telephonic feature is the trusted user, enabling access to the telephonic feature requested by the trusted user. In one embodiment, subsequent to determination of the trusted user is requesting the access to the telephonic feature, the determination unit 210 enables access to the telephonic feature requested by the trusted user.
[0066] At 408, the method 400 includes the step of in response to determining, the user requesting the access to the telephonic feature is the non-trusted user, requesting an authentication code from the non-trusted user to access the telephonic feature. In one embodiment, subsequent to determination of the non-trusted user requesting the access to the telephonic feature, the determination unit 210 requests an authentication code from the non-trusted user to access the telephonic feature. In an alternate embodiment, in case a verification process related to the authentication code is not available in the system 108 then an alternate verification process is employed to enable the telephonic feature such as the international call for the non-trusted user.
[0067] At 410, the method 400 includes the step of retrieving the authentication code from the non-trusted user. In response to requesting an authentication code from the non-trusted user to access the telephonic feature, the determination unit 210 retrieves the authentication code from the non-trusted user.
[0068] At 412, the method 400 includes the step of validating the authentication code retrieved from the non-trusted user. In one embodiment, validation unit 212 of the processor 202 is configured to validate the authentication code retrieved from the non-trusted user. The validation unit 212 analyses the pre-approved feature list as defined for the non-trusted user by the admin. Further the validation unit 212 retrieves the authentication code as defined in the pre-approved feature list. Thereafter, the validation unit 212 compares the authentication code retrieved from the pre-approved feature list with the authentication code retrieved from the user in order to validate the authentication code retrieved from the non-trusted user.
[0069] At 414, the method 400 includes the step of enabling access to the non-trusted user for the requested telephonic feature, in response to the validation of the authentication code. In one embodiment, subsequent to validating the authentication code retrieved from the non-trusted user, the validation unit 212 enables access to the non-trusted user for the requested telephonic feature. For example, subsequent to validating the authentication code retrieved from the employee, which is a non-trusted user of the enterprise, the validation unit 212 enables that employee to access the international calling service.
