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.

Claims

1. A method for receiving cell broadcast messages, comprising:

monitoring a cell broadcast channel for a continuous scan time to obtain a number of repetitions, a periodicity, and a slot number;

calculating slots where a desired message is expected in the cell broadcast channel; and

reading the cell broadcast channel only at the calculated slots.
