In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive a priority list associated with preferred radio frequencies from a serving base station. In certain aspects, each radio frequency of the preferred radio frequencies associated with a first set of base station may operate on a first RAT. In certain other aspects, the apparatus may determine if the UE is able to reselect to the first RAT. In certain other aspects, the apparatus may perform a rank-based cell reselection procedure based on signal strength when the UE is unable to reselect to the first RAT.

Techniques are described for power conservation in emergency broadcast message reception in a wireless communications system. In accordance with a method for conserving power, one or more segments of an emergency broadcast message in an access stratum are received. The emergency broadcast message is identified as a duplicate emergency broadcast message based at least in part on one or more identifiers of the received one or more segments. The receipt of additional segments of the emergency broadcast message is terminated.

A method for receiving cell broadcast messages is described. The method includes communicating with a first cell. The method also includes switching to communicating with a second cell. A cell broadcast channel is read after switching cells. The method further includes switching from a dedicated mode to a packet idle mode. The cell broadcast channel is reread once after switching from a dedicated mode to a packet idle mode. Other aspects, embodiments and features are also claimed and described.

Receiving cell broadcast (CB) messages

In an embodiment, a wireless communications device (WCD) is provisioned with a plurality of subscriber identity modules (SIMs). The WCD determines a first set of bands (BAND) that is associated with a first SIM and a second set of bands (BAND) associated with a second SIM. In a first embodiment, the WCD generates a combined band for the first and second SIMs and then scans the combined band to detect a set of target networks for camping in association with at least the first and second SIMs. In a second embodiment, the WCD scans BANDto detect a first set of target networks for camping in association with the first SIM, and then excludes, from the BAND, bands that overlap with BAND. The WCD then scans the reduced BANDto detect to detect a second set of target networks for camping in association with the second SIM.
