4. The Public Warning and Disaster Prevention Messages Reception Function.
4.1 This test is suitable for terminal devices with access voice services function that have been provided by mobile broadband service operators.
4.2 The public warning system (PWS) refers to the use of cell broadcast service (CBS) function of the mobile communication system. The CBS message identifier (MI) and the PWS alert contents will be sent by the base station to the receiving system of the terminal devices of a certain area.
4.3 Terminal devices should have the ability to receive the message identifier (MI) and display PWS alert contents.
4.3.1 The language of the contents PWS alerts, message identifier, classification, preset receiving on or off, and the options of subscribers, etc shall comply with the provisions of table 5.1.
4.3.2 The mobile device has been set up to receive the PWS message identifier (MI). When the mobile device receives the PWS alert, the device should clearly display the alert text and the message identifier (MI) in the subject header. See Figure 1 as a reference.
4.3.3 Each message identifier shall be tested respectively following a PWS alert text.
(1) The language of the PWS content in Traditional Chinese:
[The message for public warning message Testing] Your mobile phone operator has set up cell broadcasting systems for transmitting public warning messages. Now this service is still in trial. We apologize for any inconvenience it may cause and appreciate your kind understanding.
National Communications Commission
(2) The language of the PWS content in English:
[The message for public warning message Testing] Your mobile phone operator has set up cell broadcasting systems for transmitting public warning messages. Now this service is still in trial. We apologize for any inconvenience it may cause and appreciate your kind understanding.
National Communications Commission
4.3.4 Mobile devices should have the ability to recall alert messages for review by the subscriber.
4.3.5Mobile devices shall not support any user interface capabilities to forward received PWS alerts, or to copy and paste PWS alert contents.
4.4 Audio signal:
4.4.1 The audio signal shall be categorized into two kinds of signal: audio attention signal and audio general signal.
(1) Audio attention signal:
A. The audio attention signal shall have special audio frequency and special break duration. The audio attention signal shall not be set up by the subscriber or modified.
(A) Special audio frequency:For devices that have polyphonic capabilities, the audio attention signal must consist of the fundamental frequencies of 853Hz and 960Hz transmitted simultaneously. For devices with only a monophonic capability, the audio attention signal must be 960Hz.
(B) Special break duration:The audio attention signal must have a temporal pattern of one long tone of two seconds, followed by two short tones of one second each, with a half second interval between each tone. The entire sequence must be repeated twice with a half second interval between each repetition.
(C) The temporal pattern of audio attention signal is shown in Figure 2.
B. The audio attention signal must be restricted to use for alert messages under PWS.
(2) The audio general signal does not have special audio frequency and special break duration. Audio general signal shall be set up by the subscriber or modified into other pattern. When the mobile device receives the message, it shall produce the audio signal.
4.4.2 Generating timing: The mobile device has been set up to receive the PWS message identifier (MI). When mobile device receives the PWS alert, the device should produce corresponding audio signal as shown in Table 5.2 in accordance with the message identifier (MI) and the subscriber's setting.
4.4.3The audio signal is considered to be an opt-out by the subscriber with the initial default configuration being that all emergency alerts are enabled.
4.4.4 When the mobile device activates the audio signal, the subscriber may deactivate that audio signalearly.
4.5 The vibration cadence:
4.5.1 The vibration cadence shall be divided into two kinds of cadences: vibration attention cadence and vibration general cadence.
(1) Vibration attention cadence:
A. The vibration attention cadence must have the special break duration. The vibration attention cadence shall not be set up by the subscriber or modified.
(A) Special break duration:The vibration attention cadence must have a temporal pattern of one long vibration of two seconds, followed by two short vibrations of one second each, with a half second interval between each vibration. The entire sequence must be repeated twice with a half second interval between each repetition.
(B) The temporal pattern of vibration attention cadence is shown in Figure 3.
B. The vibration attention cadence must be restricted to use for alert messages under PWS.
C. The signal between vibration attention cadence and audio attention signal does not need to be synchronized.
(2) The vibration general cadence does not have special break duration. When the mobile device receives the message, the device will produce the vibration general cadence.
4.5.2 Generating timing: the mobile device has been set up to receive the PWS message identifier (MI). When mobile device receives the PWS alert, the device should produce corresponding vibration cadence as shown in Table 5.2 in accordance with the message identifier (MI) and the subscriber's setting.
4.5.3 The vibration cadence is considered to be an opt-out by the subscriber with the initial default configuration being that all emergency alerts are enabled.
4.5.4 When mobile the device activates the vibration cadence, the subscriber may deactivate that vibration cadence early.
4.6 The presentation of the received PWS alert message should take priority over other mobile device functions. The PWS alert message shall not preempt an active voice or data session.
4.7 Measuresof handling duplicate PWS alert messages:
4.7.1 Duplicate PWS alert message refers to PWS alert messages with the same message identifier and serial number, indicating that they have been sent repeated. The definition of serial number shall refer to the technical standard 3GPP TS 23.041.
4.7.2 Wherethe equipment receives duplicate PWS alert message from the base station, it shall not show the message content or generate signal and vibration.
