/**
* Parcelable object containing a received cell broadcast message. There are four different types
* of Cell Broadcast messages:
*
* <ul>
* <li>opt-in informational broadcasts, e.g. news, weather, stock quotes, sports scores</li>
* <li>cell information messages, broadcast on channel 50, indicating the current cell name for
* roaming purposes (required to display on the idle screen in Brazil)</li>
* <li>emergency broadcasts for the Japanese Earthquake and Tsunami Warning System (ETWS)</li>
* <li>emergency broadcasts for the American Commercial Mobile Alert Service (CMAS)</li>
* </ul>
*
* <p>There are also four different CB message formats: GSM, ETWS Primary Notification (GSM only),
* UMTS, and CDMA. Some fields are only applicable for some message formats. Other fields were
* unified under a common name, avoiding some names, such as "Message Identifier", that refer to
* two completely different concepts in 3GPP and CDMA.
*
* <p>The GSM/UMTS Message Identifier field is available via {@link #getServiceCategory}, the name
* of the equivalent field in CDMA. In both cases the service category is a 16-bit value, but 3GPP
* and 3GPP2 have completely different meanings for the respective values. For ETWS and CMAS, the
* application should
*
* <p>The CDMA Message Identifier field is available via {@link #getSerialNumber}, which is used
* to detect the receipt of a duplicate message to be discarded. In CDMA, the message ID is
* unique to the current PLMN. In GSM/UMTS, there is a 16-bit serial number containing a 2-bit
* Geographical Scope field which indicates whether the 10-bit message code and 4-bit update number
* are considered unique to the PLMN, to the current cell, or to the current Location Area (or
* Service Area in UMTS). The relevant values are concatenated into a single String which will be
* unique if the messages are not duplicates.
*
* <p>The SMS dispatcher does not detect duplicate messages. However, it does concatenate the
* pages of a GSM multi-page cell broadcast into a single SmsCbMessage object.
*
* <p>Interested applications with {@code RECEIVE_SMS_PERMISSION} can register to receive
* {@code SMS_CB_RECEIVED_ACTION} broadcast intents for incoming non-emergency broadcasts.
* Only system applications such as the CellBroadcastReceiver may receive notifications for
* emergency broadcasts (ETWS and CMAS). This is intended to prevent any potential for delays or
* interference with the immediate display of the alert message and playing of the alert sound and
* vibration pattern, which could be caused by poorly written or malicious non-system code.
