Abstract: In an aspect of the disclosure, a method of wireless communication is provided. The method may include starting a first timer for changing to a first network cell with a first radio access technology (RAT) and starting a second timer for changing to a second network cell with a second RAT. Further, the method may include changing to the first network cell when the first timer expires. The method may also include determining that the second network cell satisfies a cell change condition and continuing to run the second timer after the change to the first network cell in response to the second network cell satisfying the cell change condition. The method may further include changing to the second network cell after starting a third timer for a third network cell with the first RAT, a duration of the second timer being longer than a duration of the third timer.

Abstract: Aspects of the methods and apparatus relate to performing call recovery after a call drop. A cell selection update procedure may be initiated to recover a call in response to the call being dropped with a serving cell. Link conditions may be determined for the serving cell and for different candidate cells. The aspects of the methods and apparatus also include selecting a cell, based on the link conditions, from among the serving cell and a candidate cell with a highest signal power parameter in a Primary Common Control Physical Channel (PCCPCH) across a set of neighboring frequencies of the different candidate cells. Call recovery may be performed using the selected cell. In some aspects, the highest signal power parameter may be a highest Received Signal Code Power (RSCP).
