The following describes the method for sending an early warning message in the embodiment of the present invention, please participate in the diagram.

The method for sending an early warning message in the embodiment of the present invention includes:

101. Determine a quantity of system information required to send an alert message;

The foregoing warning message is: an ETWS secondary notification message or a CMAS notification message, where the system information (ie, SI) is used to carry the segmentation data of the foregoing warning message.

The size of the data of the warning message is different, and the alarm message sending processing apparatus in the embodiment of the present invention may be based on the data volume of the warning message to be sent and the current network bandwidth limitation. The upper limit of the amount of data that can be carried by each SI, and the number of SIs required to send the warning message is determined. For example, when the data size of the warning message is 9400 Bytes, the current network bandwidth limit is the upper limit of the amount of data that can be carried by each SI. 90 Byte, the warning message transmission processing device can determine that the number of system information required to send the warning message will be equal to "9400/90], that is, 105.

The maximum value is N, and the above N is not less than the number of system information required to send the early warning message determined by step 101 minus one value.

For example, if the warning message is an ETWS secondary notification message, the ETWS secondary notification message is included in the System Information Block (SIB, in the Long Term Evolution (LTE) Radio Resource Control (RRC). In the System Information Block 11 , the SIB 11 is carried by the SI. Therefore, when the step 101 determines that the number of SIs required to transmit the ETWS secondary notification message is greater than 64, the early warning message transmission processing apparatus may carry the first score in the SIB 11 of the SI. The segment number indication information, when the first segment number indication information is a value 0, represents that the SI is the first segment of the ETWS secondary notification message, and when the first segment number indication information is a value of 1, the representative The SI is the second segment of the ETWS secondary notification message, and so on.

In an application scenario, the upper limit of the data size of the foregoing warning message is limited (the upper limit is generally 9600 Bytes). Therefore, the number of SIs required to send an alert message cannot exceed 255 under normal conditions. Therefore, this Embodiments of the invention may set the above N to be equal to 255. Certainly, in the different application scenarios, the value of N may be set to be not less than 63, which is not limited herein. It should be noted that the apparatus for transmitting the early warning message in the embodiment of the present invention may be a transmitting node such as a base station or a relay node, or may be independent of the device of the transmitting node, which is not limited herein.

For example, when the SI received by the early warning message receiving device carries the first segment number indication information as a value 0, the representative SI is the first segment of the alert message, and is received by the alert message receiving device. When the SI carries the first segment number indication information as the value 1, the representative SI is the second segment of the alert message, and so on. When the first segment number indication information is the value N, it represents The SI is the (N+1)th segment of the alert message. It should be noted that, in the embodiment of the present invention, whether the SI is the last segment of the early warning message is indicated by another parameter, for example, the parameter warningMessageSegmentType is specified in the LTE RRC to indicate whether the SI is the last segment of the alert message, When the warningMessage SegmentType value is notLastSegment, it indicates that the SI is not the last segment of the alert message. When the warningMessageSegmentType value is LastSegment, it indicates that the SI is the last segment of the alert message.

In an application scenario, the upper limit of the data size of the foregoing warning message is limited (the upper limit is generally 9600 Bytes). Therefore, the number of SIs required to send an alert message cannot exceed 255 under normal conditions. Therefore, this Embodiments of the invention may set the above N to be equal to 255. Of course, in different application scenarios, the above N may be set to other values not less than 63, which is not limited herein.

In another application scenario, if the SI received in step 301 only carries the second segment number indication information, the alert message receiving device determines, according to the second segment number indication information, that the SI received in step 301 is in the foregoing alert. a location in all the system information of the message, where the second segment number indication information is used to indicate that the received SI is the first system information of the foregoing warning message, and the maximum value supported by the second segment sequence number indication information is 63.
