1. A method, comprising:
at a user equipment (UE) configured with a wireless network connection:
establishing a multimedia data stream with a further UE;
transmitting, at a first time, the multimedia data stream using a first video codec tier;
identifying a likelihood of an inter-radio access technology (iRAT) handover at the further UE;
when the likelihood of the iRAT handover is determined, transmitting, at a second time, the multimedia data stream using a second video codec tier based on the likelihood of the iRAT handover, wherein the second video codec tier is less than the first video codec tier;
determining whether an amount of data to be transmitted over a time window satisfies a first predetermined threshold; and
when the first predetermined threshold is not satisfied, increasing the second video codec tier to a third video codec tier, wherein the third video codec tier is based on at least one of information from a medium access control (MAC) layer of the UE or information from a transmission control protocol/Internet protocol (TCP/IP) layer of the UE.
