Abstract
A device automatically is configured to the emergency alert system (EAS) channel utilized by the location from which the device registers with a network. In an example configuration, an EAS server provides a mobile switching center (MSC) configuration information regarding the emergency alert channels to be used for the cellular sites supported by the MSC. When the mobile device registers via a cellular site supported by the MSC, the designated channel to be used for EAS messages is sent to the mobile device as part of the registration process. The mobile device assigns an internal channel to the designated channel. In another example configuration, the mobile device is preconfigured with a table listing all possible EAS channels, and the MSC provides, during the registration process, a pointer to the appropriate portion of the table.
