Abstract
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.
