Abstract: Methods, systems, and devices are described for transitioning between different radio access technologies (RATs) utilizing system information messages to trigger the transition. Some embodiments may involve utilizing a system information message (e.g., SIB19, SI2quater) that may be received from a serving cell over a first radio RAT (e.g., 2G, 3G, 4G) while in a connected mode with the serving cell. A transition may be initiated from the connected mode with the serving cell to an idle mode with the serving cell in response to the received system information message. A reselection may be performed from the idle mode with the serving cell to a target cell utilizing a second RAT (e.g., 3G, 4G, or 5G) in response to the received system information message.

Abstract: To carry out inter-RAT handover to the strongest neighbor cell, a method, a computer-readable medium, and an apparatus are provided. The apparatus determines a measurement configuration relating to handover from a cell of a source RAT to a cell of one or more target RATs. The apparatus detects trigger events associated with a first cell and a second cell of the one or more target RATs and a serving cell of the source RAT based on the measurement configuration. The apparatus may prioritize the second cell over the first cell in response to the detected trigger events, e.g., based on the received signal strength of the cells. The apparatus may generate a MRM for each of the first cell and the second cell. The MRM for the second cell may be sent to the serving cell before the MRM for the first cell is sent to the serving cell.
