A wireless communication device performs a method for determining when to trigger a handover of a communication session from a first access network to a second access network. The method includes determining, for an active communication session, a set of outgoing traffic statistics for outgoing traffic sent by the wireless communication device using the first access network and determining, for the active communication session, a set of incoming traffic statistics for incoming traffic received by the wireless communication device using the first access network. The method further includes analyzing the incoming and outgoing traffic statistics and determining when to trigger a handover of the active communication session from the first access network to the second access network based on the analysis of the incoming and outgoing traffic statistics.
