10. The integrated circuit of claim 7 , wherein the circuitry configured to implement the mechanism based on the predetermined condition:
identifies second measurement data satisfies a second predetermined threshold, wherein the iRAT handover from the WLAN to the cellular network is performed based on the second predetermined threshold.
11. The integrated circuit of claim 10 , wherein the first measurement data and the second measurement data comprises data for one of a same parameter or a different parameter.
12. The integrated circuit of claim 10 , further comprising:
circuitry configured to, prior to the iRAT handover, transmit the multimedia data stream to the further UE over both the WLAN connection and the cellular network connection.
13. A user equipment (UE), comprising:
a transceiver configured to connect to one or more wireless networks; and
a processor communicatively coupled to the transceiver and configured to perform operations comprising:
establishing a multimedia data stream with a further UE;
