Abstract
A radio access network element includes a cellular interface and a processor. The cellular interface is configured to communicate with the user equipment via a cellular link. The processor is configured execute computer readable instructions to cause the radio access network element to: transmit a plurality of probe packets to the user equipment via an IP tunnel between the radio access network element and the user equipment through a wireless local area network access point; receive a probe packet response from the user equipment, the probe packet response being indicative of a connection quality of the IP tunnel between the radio access network element and the user equipment; and determine whether to switch from a first traffic routing mode to a second traffic routing mode based on the probe packet response from the user equipment.
