Abstract

In embodiments, a user equipment (UE) may include an applications module and a communications module. The applications module may run an application and facilitate communications between the application and a remote server over a wireless communication network. The communications between the application and the remote server may initially be over a first interface selected based on a route table. The communications module may identify a second interface that is preferred to the first interface. The communications module may modify the route table to prioritize the second interface over the first interface. Additionally, the communications module may instruct the applications module to execute a reset operation to re-establish communications between the application and the remote server using the second interface.
