SYSTEM AND METHOD FOR ESTABLISHING A COMMUNICATION

This International Application claims priority from a complete patent application filed in India having patent application number 202021023925, filed on June 8, 2020 and titled “SYSTEM AND METHOD FOR ESTABLISHING A COMMUNICATION”.

FIELD OF INVENTION

Embodiments of a present disclosure relate to a communication system, and more particularly to, a system and method for establishing the communication.

BACKGROUND

Effective communication plays an important role in business and in development of world. One of the principal standards for a mobile communication is the Global System for Mobile Communication (GSM). A central feature of the GSM standard is the Subscriber Identity Module (SIM) or a universal integrated circuit card. For a UICC to establish an IP connection with the IP Server can be done using a “Class e” Bearer Independent protocol (BIP) supported terminal. The session is initiated by the UICC to the IP Server since the request initiated by the IP Server to the UICC is not possible directly as the IP Server is not aware of the IP Address allocated to the UICC once the data session is active. Therefore, the mechanism to initiate an IP session between the IP Server and the UICC is using PUSH or the POLL mechanism from the UICC itself.

Conventionally, the system, which is available for establishing the communication between the Server and the UICC over IP uses an initial short message service (SMS) PUSH as a trigger signal to indicate the UICC to initiate the IP session, which is the only available approach apart from the polling mechanism. However, the PUSH SMS initiated by the Server can be expensive especially if one or more users associated with the universal integrated circuit card are on roaming, which becomes very expensive. Furthermore, if the server needs to switch between one or more mobile network operators (MNO) profiles or subscriptions within the universal integrated circuit card then the respective short message service center (SMSC) binding to the SMS gateway, which is handled by an internet protocol (IP) server platform such as Over-the Air (OTA), Remote SIM Provisioning (RSP) and the like, may lead to complex configurations. Furthermore, the short service message (SMS) may take longer time in establishing the connection due to the intermediate SMSC, which in turn makes such process a time-consuming.

Hence, there is a need for an improved system and a method for establishing a communication in order to address the aforementioned issues.

In such embodiment, the method (220) may include sending a request from the mobile service (MS) to a visited service (GPRS) support node (SGSN) for the data access once the MS is attached to the visited network. In one embodiment, the method (220) may include trying to locate the one or more details associated with the server of a gateway (GPRS) support node (GGSN) by an access point name (APN) and the visited service (GPRS) support node (SGSN). Further, in one embodiment, the method (220) may include identifying the one or more details of the gateway (GPRS) support node (GGSN) and may be communicated to the visited service (GPRS) support node (SGSN). In such embodiment, the method (220) may include sending a request to the home gateway (GPRS) support node (GGSN), which assigns the internet protocol (IP) to create a data transfer tunnel for the communication.

Various embodiments of the present disclosure provide a technical solution to the problem of establishing a communication. The present system provides an efficient system to establish the communication as the system provides an on-demand session establishment that triggers a targeted universal integrated circuit card for an internet protocol (IP) session at any point of time as required, which makes the system very reliable and comfortable for a user. Further, the present system uses a call mechanism to generate trigger signals, which makes the system very inexpensive and fast. Further, the present disclosure makes it very easy for multi international mobile subscriber identity (IMS I) to work smoothly by using call mechanism instead of a short message service centre (SMSC).
