Abstract:
1. A method comprising: receiving, by a user device, an access request to access an application provided by a cellular carrier associated with the user device, using, by the user device, a first type of tunneling protocol to attempt to establish a connection, via an evolved packet data gateway (ePDG), to a server that provides the application; determining, by the user device, that the connection is not established using the first type of tunneling protocol based on receiving a message that indicates a failure to establish the connection using the first type of tunneling protocol or based on not receiving a response to a request to establish the connection within a particular period of time, using, by the user device, a second type of tunneling protocol to establish the connection based on determining that the connection is not established using the first type of tunneling protocol, using, by the user device, the connection to access the application via the ePDG.
