System and method for providing services to a user equipment in an inter-national location
Embodiments of the present invention relate to systems and methods for one of restricting at least one service and providing one of the at least one service and a differential service to a subscriber, the method comprising steps of: receiving a connection request from a user equipment [ 102 ]; determining a location status of the subscriber, wherein the location status comprises one of an intra-national location and an inter-national location; generating one of a positive response in an event a source IP address is identified in a pre-stored list of source IP address and a negative response is in an event the source IP address is not identified in the pre-stored list of source IP address; and one of restricting the at least one service and providing one of the at least one service and the differential service to the subscriber.
1. A method for one of restricting at least one service and providing one of the at least one service and a differential service to a subscriber including a user profile, wherein the subscriber is associated with a unique subscriber identity module (SIM) identifier of a subscriber identity module, the method comprising steps of:
receiving a connection request from a user equipment, wherein
the connection request includes a source internet protocol (IP) address of the user equipment, a domain name server (DNS) IP address of the subscriber, and the unique SIM identifier;
determining a location status of the subscriber based on a comparison of the DNS IP address with a pre-defined list of DNS IP address, wherein the location status comprises one of an intra-national location and an inter-national location;
generating one of a positive response and a negative response based on a comparison of the source IP address with a pre-stored list of source IP address, wherein
the positive response is generated in an event the source IP address is identified in the pre-stored list of source IP address, and
the negative response is generated in an event the source IP address is not identified in the pre-stored list of source IP address;
one of restricting the at least one service and providing one of the at least one service and the differential service to the subscriber, wherein
the at least one service is restricted in an event of, the generation of the negative response and the determination of the intra-national location,
the at least one service is provided in an event of, the generation of the positive response and the determination of the intra-national location, and
the differential service is provided in an event of, the generation of the negative response and the determination of the inter-national location.
2. The method as claimed in claim 1 , further comprising providing one of the at least one service and the differential service to the subscriber in an event the subscriber is latched with a cellular network.
3. The method as claimed in claim 1 , further comprising providing the differential service based on one of the user profile, a subscription information;
wherein the user profile comprises at least one of: the unique SIM identifier, the source IP address, the DNS IP address, a last state information and a last location status of the SIM.
4. The method as claimed in claim 1 , wherein the at least one service and the differential service comprises one of a voice-over Wi-Fi audio call, a voice-over Wi-Fi video call, a voice-over Wi-Fi message.
5. The method as claimed in claim 1 , wherein the unique SIM identifier comprises one of a mobile country code, an international mobile subscriber identifier, a mobile station international subscriber directory number and a unique mobile identification number.
6. A network entity for one of restricting at least one service and providing one of the at least one service and a differential service to a subscriber including a user profile, wherein the subscriber is associated with a unique subscriber identity module (SIM) identifier of a subscriber identity module, the network entity comprising:
an authoritative domain name server (DNS) server configured to:
maintain a predefined list of DNS internet protocol (IP) address,
receive a connection request from a user equipment, wherein the connection request includes a source IP address of the user equipment, a DNS IP address of the subscriber, and the unique SIM identifier,
identify a location status of the subscriber based on a compare of the DNS IP address with the predefined list of DNS IP address to, wherein the location status comprises one of an intra-national location and an inter-national location;
a firewall configured to:
maintain a predefined of source IP address;
generate one of a positive response and a negative response based on a comparison of the source IP address with a pre-stored list of source IP address, wherein the positive response is generated in an event the source IP address is identified in the pre-stored list of source IP address, and the negative response is generated in an event the source IP address is not identified in the pre-stored list of source IP address; and
a decision engine configured to:
one of restrict the at least one service and provide one of the at least one service and the differential service to the subscriber, wherein
the at least one service is restricted in an event of, the generation of the negative response and the determination of the intra-national location,
the at least one service is provided in an event of, the generation of the positive response and the determination of the intra-national location, and
the differential service is provided in an event of, the generation of the negative response and the determination of the inter-national location.
7. The system as claimed in claim 6 , further comprising an authentication server for comparing the source IP address with a pre-stored list of source IP address in an event the location status is inter-national.
8. The system as claimed in claim 6 , wherein the authentication server further configured to retrieve the user profile from one of a home packet gateway and an international packet gateway;
wherein the user profile comprises at least one of: the unique SIM identifier, the source IP address, the DNS IP address, a last state information and a last location status of the SIM.
9. The system as claimed in claim 6 , wherein the decision engine is further configured to provide the differential service based on one of the user profile, and a subscription information;
wherein the user profile comprises at least one of: the unique SIM identifier, the source IP address, the DNS IP address, a last state information and a last location status of the SIM.
10. The system as claimed in claim 6 , wherein the at least one service is provided by the home packet gateway.
11. The system as claimed in claim 6 , wherein the differential service is provided by a home/international packet gateway.
12. The system as claimed in claim 6 , wherein the at least one service and the differential service comprises one of a voice-over Wi-Fi audio call, a voice-over Wi-Fi video call, a voice-over Wi-Fi message.
