Abstract:
Techniques are disclosed relating to a mobile device that initiates handovers from short-range networks to long-range networks. In various embodiments, a mobile device includes one or more radios that communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. In such an embodiment, the mobile device stores an indication that the cellular RAT is a preferred RAT for a communication session. The mobile may establish the communication session using the preferred RAT, and in response to determining that a quality of the preferred RAT fails to satisfy a set of quality criteria, may request that the communication session use the short-range RAT. In some embodiments, the mobile device analyzes average packet error rate for the communication session and in response to the average packet error rate satisfying a threshold, requests that the communication session use the cellular RAT.
