Filed:

Appl. No.:

15/365817

Inventors:

International Classification:

H04W 60/02
H04L 29/06
H04W 60/04

Abstract:

In instances where a user equipment (UE) encounters an issue during an attempt to subscribe for registration status, the UE is configured with improved logic for handling the encountered issue. For instance, the UE may transmit a number of subsequent registration requests up to a predetermined number of registration requests before ultimately refraining from transmitting any additional registration requests. The UE may also wait until a lapse of a period of time before transmitting any next registration request and/or subscription request, thereby giving the carrier network sufficient time to resolve any recoverable issues before transmitting a next registration request and/or subscription requests. On subsequent iterations, the time period may be incremented to provide longer and longer wait times before transmitting subsequent registration requests and/or subscription requests.

Abstract:

Wi-Fi calling using a mobile device and an evolved packet data gateway (ePDG) is described herein. For example, a mobile device may determine whether any LTE coverage is available, whether data roaming is available, whether a visited public land mobile network (VPLMN) is available, and whether a DNS query to a visited ePDG (VePDG) is successful. The mobile device may connect to the VePDG responsive to a determination that LTE coverage is available, that data roaming is available, that a VPLMN is available, and that the DNS query to the VePDG is successful. Otherwise, the mobile device may connect to a home ePDG (HePDG).
