Abstract:
A method, a computer-readable medium, and an apparatus for switching between a first radio access network (RAN) using the first radio access technology (RAT) and the second RAN using a different, second RAT are provided. The method includes switching a wireless device operating at a first signal frequency in the first RAN to a second RAN and switching from the second RAN back to the first RAN. In an aspect, the wireless device is switched to one of the cells operating at the first signal frequency in the first RAN if each signal parameter from the one of the cells satisfies a criterion. The wireless device is otherwise switched to another one of the cells operating at a second signal frequency in the first RAN based on parameters from the another one of the cells. The first signal frequency is different from the second signal frequency.
