Abstract

Systems, methods and non-transitory computer-readable mediums are provided for an entitlement system and method having an E911 address check bypass function. Methods provided herein include receiving a request from a mobile device for enabling voice over WiFi (VoWiFi) service and checking E911 address status. Methods further include applying a filter to the request to determine that the E911 address check can be bypassed and transmitting a response to the mobile device indicating that E911 address status is not required and that VoWiFi connection is permitted, thereby bypassing the E911 address check.

First claim

What is claimed is:

1 . A method comprising:
receiving a request from a mobile device for enabling voice over wi-fi (VoWiFi) service and checking E911 address status; applying a filter to the request to determine that the E911 address check can be bypassed; and transmitting a response to the mobile device indicating that E911 address status is not required and that VoWiFi connection is permitted, thereby bypassing the E911 address check.

2 . The method of claim 1 , further comprising starting a timer upon transmitting the response to the mobile device.

3 . The method of claim 2 , further comprising triggering a secured push notification to the mobile device upon expiration of the timer.

4 . The method of claim 3 , further comprising receiving a further request to check the E911 address status in response to the push notification.

5 . The method of claim 4 , further comprising determining that the further request is in response to an expired bypass and proceeding with the E911 address check.

6 . The method of claim 5 , further comprising allowing VoWiFi for the mobile device after the expired bypass when the E911 address check is successful.

7 . The method of claim 5 , further comprising disallowing VoWiFi for the mobile device when the E911 address check is unsuccessful.

8 . The method of claim 1 , wherein the filter comprises additional information about the mobile device.

9 . The method of claim 1 , wherein the filter comprises at least one of a source internet protocol (IP) address, a client operating system, an international mobile subscriber identity (IMSI) range or an international mobile equipment identity (IMEI).

10 . The method of claim 9 , further comprising applying the IMEI filter and permanently disabling the E911 address check based on the IMEI filter.

11 . A system comprising:
a memory storing instructions; and a processor accessing the memory and executing the instructions to perform operations including: receiving a request from a mobile device for enabling voice over wi-fi (VoWiFi) service and checking E911 address status; applying a filter to the request to determine that the E911 address check can be bypassed; and allowing the mobile device to connect to VoWiFi without an E911 address check.

12 . The system of claim 11 , the system further comprising communications circuitry transmitting a response to the mobile device indicating that VoWiFi is allowed and the E911 address check is not required.

13 . The system of claim 12 , the operations further comprising starting a timer upon transmitting the response to the mobile device.

14 . The system of claim 13 , the operations further comprising triggering a secured push notification to the mobile device upon expiration of the timer.

15 . The system of claim 14 , the operations further comprising receiving a further request to check the E911 address status in response to the push notification.

16 . The system of claim 15 , the operations further comprising determining that the further request is in response to an expired bypass and proceeding with the E911 address check.

17 . The system of claim 11 , wherein the filter comprises additional information about the mobile device.

18 . A method comprising:
sending a request from a mobile device for enabling voice over wi-fi (VoWiFi) service and checking E911 address status; receiving a determination in response to the request, based on an applied filter, that the E911 address check can be bypassed; and connecting to VoWiFi based on the determination.

19 . The method of claim 18 , wherein sending the request comprises sending at least one of a source IP address, a client operating system, a client IMSI range or an IMEI for use as the applied filter.

20 . The method of claim 19 , further comprising receiving a secured push notification upon expiration of a timer sending another request for an E911 address check in response to the secured push notification.
