Customer service is important because it inspires customer loyalty and makes employees' jobs easier. This, in turn, helps businesses grow. By providing great customer service, organizations can recover customer acquisition costs, retain talent, and foster brand loyalty. Customer service is important because it's the direct connection between your customers and your business. It retains customers and extracts more value from them. By providing top-notch customer service, businesses can recoup customer acquisition costs.
[0003] It may happen so that a customer wants to connect with the customer care service instantly and not at some random time when the customer is not free or when the customer does not have the information required for the call handy, etc. For example, the customer is at home and has all the information required handy at home for the call, he would want an instant call back and get the service or query addressed instantly.
[0004] In current customer services, when a customer requests a call back over a chat application or via email or a bot chat, the customer may not get the call back instantly and sometimes, is not even committed an exact time slot or time at which the customer will receive the call from the customer care. Once a request for the call is submitted, the customer in this case just waits to receive the call from an unknown number. Sometimes the wait is just too long, and the customer might just miss the call.
[0005] Therefore, it is desired that the customer care service calls are managed in a more efficient manner and create better customer experience. The customer should be able to connect to the customer care when he wants, preferably instantly and should not be kept waiting for the call event to happen at any random time. Therefore, there is a need for a system and method in the art which is able to handle and manage the customer care calls in a more efficient manner and provide instant call back.

[0046] In an embodiment, the generation unit 218 of the processor 202 is configured to generate, utilizing the selected network element 110 a session ID based on receiving the enriched click to call request. In particular, the generation unit 218 generates the session ID in order to establish the call between the user and the third party utilizing the selected network element 110. The session ID is a unique identification number that is generated by the generation unit 218. This unique identification number includes at least one of, but not limited to, a number code, a numerical code, or an alphanumeric code. The session ID is also known as a session token which is assigned to the user for the duration of a session established between the user and the third party.
[0047] In an embodiment, the initiation unit 220 of the processor 202 is configured to initiate, utilizing the selected network element 110, the instant click to call service based on the generated session ID by the generation unit 218 between the user and the third party.
[0048] In an alternate embodiment, it is to be noted that the generation unit 218 and the initiation unit 220 are included in the selected network element 110 without deviating from the scope of the present disclosure.
[0049] Subsequent to initiating the instant click to call service between the user and the third party, the transceiver unit 208 transmits a notification to the user pertaining to at least one of, but not limited to, a successful instant click to call service and a failed instant click to call service. For example, upon initiating the call, if the call is not completed due to one or more issues such as at least one of, but not limited to, a poor network, the user leaving the call midway, etc., then the user will get the notification regarding the same.

In other examples, the processor 202 may be implemented by electronic circuitry.
[0052] FIG. 3 illustrates an exemplary block diagram of an architecture for the system 108, according to one or more embodiments of the present invention. More specifically, FIG. 3 illustrates the system 108 configured for managing the instant click to call 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 limited to the scope of the present disclosure.
[0053] FIG. 3 shows communication between the UE 102 and the system 108. For the purpose of description of the exemplary embodiment as illustrated in FIG. 3, the 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 (as shown in FIG. 1) 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).
[0054] 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.
[0055] 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 manage the click to call request. 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.
[0056] 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 user interface 306 is configured to allow the user to transmit the click to call request. The UE 102 transmits the click to call request to the processor 202 via the user interface 306.
[0057] Initially, when the customer care calls the user/customer and let us assume due to any reason the user/customer was not able to pick up the call. Thereafter, if the user/customer immediately wants to connect with the customer care in order to get any service or to get information regarding a query, the user/customer uses the instant click to call service via the user interface 306 based on which the UE 102 transmits the click to call request to the processor 202 of the system 108.
[0058] Further, the processor 202 receives the click to call request which includes information of the user such as a phone number and authenticates the user by verifying at least one of, but not limited to, tokens, API keys, user ID, and passwords which are included in the click to call request. Subsequent to the authentication of the user, the processor 202 checks for the valid subscription plan and the access policy related to the user. Thereafter, if the processor 202 determines that the user is valid with the active subscription plan and the access policy, the processor 202 selects at least one network element 110 and creates a session ID to establish an instant call between the user/customer and the customer care. Based on the session ID created, the processor 202 utilizes the selected network element 110 to make the instant call that establishes communication between the customer care and the user/customer in real time or within a second. Advantageously, the user/customer receives a call back from the customer care instantly without waiting for a long time.
[0059] FIG. 4 is a signal flow diagram illustrating the flow for managing instant click to call service, according to one or more embodiments of the present disclosure.
[0060] At step 402, using the UE 102 the user transmits the click to call request to the processor 202 of the system 108.
[0061] At step 404, processor 202 of the system 108 receives the click to call request and validates the token received from the click to call request. Further, the API key is extracted from the validated token and the extracted API key is validated. Thereafter, the users plan and access policy are checked. If the token, the API key and the users plan and access policy are valid, then the click to call request is accepted, else the click to call request is rejected. Furthermore, the click to call request enrichment is done, then the enriched click to call request is transmitted to the network element 110 based on the availability of the network element 110.
[0062] At step 406, once the enriched click to call request reached at the network element 110, the network element 110 generates the session ID utilizing the processor 202 to initiate the instant call. The network element 110 transmits the instant call request to the third party to establish the instant call between the third party and the user.
[0063] At step 408, the network element 110 receives response related to the instant call request from the third party. Further, the network element 110 establishes the instant call between the third party and the user by transmitting a response to the UE 102 via the system 108.
[0064] FIG. 5 is a flow diagram of a method 500 managing instant click to call service, according to one or more embodiments of the present invention. For the purpose of description, the method 500 is described with the embodiments as illustrated in FIG. 2 and should nowhere be construed as limiting the scope of the present disclosure.
[0065] At step 502, the method 500 includes the step of receiving a click to call request from a user. In one embodiment, transceiver unit 208 of the processor 202 is configured to receive the click to call request from a user. In an alternate embodiment, the click to call API call is received at the transceiver unit 208 of the processor to provide the instant click to call service to the user. For example, when the user had just missed the call from the third party such as the customer care, the user transmits the click to call request from the UE 102 to avail the instant click to call service.
[0066] At step 504, the method 500 includes the step of validating a token included in the click to call request received, wherein an Application Programming Interface (API) key is extracted from the validated token in order to validate the API key. In one embodiment, the validating unit 210 of the processor 202 is configured to validate the token included in the click to call request received and extract the API key from the validated token to validate the API key. For example, the click to call request includes the token which is validated by verifying at least one of, but not limited to, the token signature by the validating unit 210. If the token included in the received click to call request is an invalid token, then a negative response is transmitted to the user.
[0067] Further, the validating unit 210 extracts the API key from the validated token and validates the API key by checking for the match between the API key extracted from validated token with the similar API key which is prestored in storage unit 206. If the extracted API key is not matching with any of the prestored API key, then the extracted API key is inferred as the invalid API key based on which the then the negative response is transmitted to the user. In an alternate embodiment, the validating unit 210 authenticates user by validating the token, and the API keys.
[0068] At step 506, the method 500 includes the step of determining whether a user’s plan and access policy is valid based on the validated API key. In one embodiment, the determination unit 212 of the processor 202 is configured to determine whether a user’s plan and access policy is valid based on the validated API key. In particular, in order to avail the instant click to call service, the user must have subscribed to the valid subscription plan and access policy which provides the instant click to call service. If the user’s plan and access policy are not valid, then a negative response is transmitted to the user. For example, the user’s plan and the access policy includes, at least one of, but not limited to, the subscription plan with a limited number of click to call request or the click to call API call are allowed to the user in a day.
[0069] At step 508, the method 500 includes the step of enriching the click to call request subsequent to determining that the user’s plan and access policy is valid. In one embodiment, the enrichment unit 214 of the processor 202 is configured to enrich the click to call request subsequent to determining that the user’s plan and access policy is valid. For example, in some scenarios the click to call request are not included with data which is required to provide instant click to call service to the user based on which the enrichment unit 214 modifies or add the required data in the click to call request. Let us assume a header value in the click to call request is not appropriate for the instant click to call service, in such scenarios the enrichment unit 214 modifies the header value so that its compatible in order to provide instant click to call service to the user.
[0070] At step 510, the method 500 includes the step of selecting at least one of, a network element in order to transmit the enriched click to call request to the network element. In one embodiment, the selection unit 216 of the processor 202 is configured to select at least one of, a network element 110 in order to transmit the enriched click to call request to the network element 110. The selection unit 216 determines the availability of at least one of, the network element 110 among the plurality of network elements based on which the selection unit 216 selects the network element 110. For example, let us assume BTAS is network element with plurality of instances such as BTAS 1, BTAS 2,…,BTAS N. Whenever the enriched click to call request is received at the selection unit 216, the selection unit 216 checks for the availability of each of the BTAS in the round robin manner. If selection unit 216 determines that the BTAS 1 is not available, then selection unit 216 will check for the BTAS 2. Subsequent to determining that the BTAS 2 is available, then the selection unit 216 transmits the enriched click to call request to BTAS 2 i.e. the network element 110. Advantageously, due to the click to call request distribution in round robin manner among the plurality of BTAS instances, the load pertaining to the click to call requests is equally divided among the plurality of BTAS instances.
[0071] At step 512, the method 500 includes the step of generating utilizing the selected network element a session ID based on receiving the enriched click to call request. In one embodiment, the generation unit 218 of the processor 202 is configured to generate the session ID utilizing the selected network element 110 based on receiving the enriched click to call request. For example, once the enriched click to call request is received, a session ID is generated by the generation unit 218 to connect an A party with a B party. Herein, the A party relates to the customer care and the B party relates to the user or vice versa.
[0072] At step 514, the method 500 includes the step of initiating utilizing the selected network element, the instant click to call service based on the generated session ID between the user and the third party. In one embodiment, the initiation unit 220 of the processor 202 is configured to initiates the instant click to call service utilizing the selected network element 110 based on the generated session ID between the user and the third party. For example, the instant call is established between the customer care and the user based on the generated session ID.
[0073] In an embodiment, subsequent to initiating the instant click to call service between the user and the third party, the transceiver unit 208 transmits the notification regarding the successful instant click to call service and a failed instant click to call service to the UE 102 of the user.
[0074] In an embodiment, if the instant call is not completed, for example, due to bad network, disconnection mid-way, user leaving the call midway, etc., the user will get a notification regarding the same.
[0075] The present invention further discloses a non-transitory computer-readable medium having stored thereon computer-readable instructions. The computer-readable instructions are executed by the processor 202. The processor 202 is configured to receive a click to call request from a user. The processor 202 is further configured to validate a token included in the click to call request received, and an Application Programming Interface (API) key is extracted from the validated token in order to validate the API key. The processor 202 is further configured to determine, whether a user’s plan and access policy is valid based on the validated API key. The processor 202 is further configured to enrich, the click to call request subsequent to determining that the user’s plan and access policy is valid. The processor 202 is further configured to select, at least one of, a network element in order to transmit the enriched click to call request to the network element. The processor 202 is further configured to generate, utilizing the selected network element a session ID based on receiving the enriched click to call request. The processor 202 is further configured to initiate, utilizing the selected network element, the instant click to call service based on the generated session ID between the user and the third party.
