- * <li>emergency broadcasts for the Japanese Earthquake and Tsunami Warning System (ETWS)</li>

- * two completely different concepts in 3GPP and CDMA.
- *
- * <p>The GSM/UMTS Message Identifier field is available via {@link #getServiceCategory}, the name

- * 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.
