This section describes how to set the traffic threshold, sending frequency limit, and number control rules, and how to restrict SMS sending areas.

Functions

Huawei Cloud Message & SMS provides you with multiple functions to reduce losses caused by service bombing.

Traffic threshold:
- Alarm value: If the total number of SMSs sent exceeds an alarm value, the platform will send alarm SMS notifications to contacts.
- Limit value: If the total number of SMSs sent reaches a limit value, the platform will send alarm SMS notifications to contacts again and automatically suspend SMS sending.
Region threshold: You can select some countries or regions. Then, SMSs will be sent only to countries or regions you select.
Number control: You can set a rule to allow or deny SMS sending to specific numbers or number segments in certain countries or regions.
Sending frequency limit: You can set limits on the frequency of SMS sending to each recipient number under the same application. Once the limit is reached, the corresponding new SMS sending fails.

You can set the SMS message sending rules as required.

Traffic Threshold

You can set the alarm value and limit value on SMS sending to protect against SMS bombing, which can result in significant unwanted fees.

Set traffic threshold based on site requirements. For details about the parameters, see Table 1.

Statistics are recorded in UTC format. As there is some delay between when the platform sends an SMS and when the SMS status is reported, the recorded total number of SMSs sent per day/month may be off by as many as 100 SMSs.

**Table 1** Traffic threshold parameters
Parameter	Description
Total Sent per Day	Total number of SMSs you request to send on each calendar day.
Total Sent per Month	Total number of SMSs you request to send in each calendar month.
Alarm Value	If the total number of SMSs sent per day/month reaches the alarm value, the platform will send alarm SMS notifications to contacts. If the total number of SMSs sent within a day reaches the alarm value, the platform will send alarm SMS notifications on the same day. The total number of SMSs sent will be cleared on the next day. If you decrease the alarm value of the total number of SMSs sent per day on the same day when you receive an alarm SMS notification, the platform will not send an alarm notification again and the new alarm value will take effect on the next day. If you increase the alarm value on the same day, the platform will send an alarm SMS notification again when the total number of SMSs sent within a day reaches the new alarm value. The same applies to the alarm value of the total number of SMSs sent per month. By default, the alarm value of the total number of SMSs sent per day is set to 400, and that of the total number of SMSs sent per month is set to 8,000.
Limit Value	If the total number of SMSs sent per day/month reaches the limit value, the platform will send alarm SMS notifications to contacts and suspend SMS sending. If the total number of SMSs sent within a day reaches the limit value, the platform will send alarm SMS notifications and suspend SMS sending on the same day. The total number of SMSs sent will be cleared and SMS sending will resume on the next day. If you decrease the limit value of the total number of SMSs sent per day on the same day when you receive an alarm SMS notification, the platform will not send a notification again and the new limit value will take effect on the next day. If you increase the limit value on the same day, SMS sending will resume, and the platform will send an alarm SMS notification again and suspend SMS sending when the total number of SMSs sent within a day reaches the new limit value. The same applies to the limit value of the total number of SMSs sent per month. NOTE: The Chinese mainland and international SMS quota is reset at 00:00 UTC+08:00. By default, the limit value of the total number of SMSs sent per day is set to 500, and that of the total number of SMSs sent per month is set to 10,000.

Setting the traffic threshold for Chinese mainland SMS
1. Click the Chinese Mainland SMS tab.
2. Click Modify and change the values based on the following rules:
  - Limit values must be greater than alarm values, and the limit value of the number of SMSs sent per month must be greater than that of the number of SMSs sent per day. Limit values and alarm values must be integers and cannot be negative, 0, or empty.
  - You can customize alarm values based on the preceding rules.
  You can increase limit values in the following ways:
  - Contact the account manager, who will send an email to the product manager to apply for increasing of the limit values. The product manager will modify the values in the backend after confirming the application.
  - If you do not know how to contact the account manager, submit a service ticket by clicking the link in the Traffic Threshold area or accessing the service ticket page through the navigation bar on the top of the console. (Partners should apply for increasing the traffic thresholds on behalf of their sub-customers. Sub-customers cannot apply for the increase by themselves.)
  1. Log in to the console. On the menu bar, choose More > Service Tickets > Create Service Ticket.
  2. Choose Services > Quotas. On the displayed page, select Quota Application and click Create Now.

  5. Wait for your application to be reviewed. The limit values will be automatically changed upon approval. You can choose Service Tickets > My Service Tickets to view your application review progress.
  New limit values will be used as the default limit values. Set limit values lower than the default values based on your service requirements.
3. Click OK to save the modification.
  If the total number of SMSs sent reaches the limit value you set, the platform will suspend SMS sending. You can increase the limit value or wait for SMS sending to automatically resume in the next day or month.

You can enable this function. Then, the system will send SMSs based on the configured number segment or number rules.

You can add number segments to a blacklist to prevent SMSs from being sent to those segments. Additionally, specific numbers within these segments can be added to a whitelist, allowing SMSs to be sent to them.

Log in to the Message & SMS console. In the navigation pane, choose General Management > Settings.
Perform the following operations as required.
- Add a rule.
  - Enter a complete number starting with a plus sign (+) and combining with an area code.
  - The Allow and Deny policies cannot be configured for a number at the same time. The Allow policy takes precedence over that in the Deny policy.
  - You can add up to 100 number segment rules and 600 number rules for each country or region.
  - Number rules can be added in batches by importing a file. The number rules in the same file must belong to the same country or region, and the number of rules cannot exceed 600.
  - After a rule is added, it takes about 5 minutes to take effect.
  1. Click Add Rule. On the displayed page, select the country or region to which the rule belongs.
  2. Add number or number segment rules based on service requirements.

    2. Click Yes in the displayed dialog box.

SMS Sending Frequency Limit

You can set limits and whitelist to prevent failure caused by sending multiple SMSs to the same number, ensuring SMS sending success rate and security.

By default, the SMS sending frequency limit function is disabled.
