**Table 7** PolicyTriggerPropertiesReq
Parameter	Mandatory	Type	Description
pattern	Yes	Array of strings	Scheduling rule. A maximum of 24 rules can be configured. The scheduling rule complies with iCalendar RFC 2445, but it supports only parameters FREQ, BYDAY, BYHOUR, BYMINUTE, and INTERVAL. FREQ can be set only to WEEKLY or DAILY. BYDAY* can be set to MO, TU, WE, TH, FR, SA, or SU (seven days of a week). BYHOUR ranges from 0 to 23 hours. BYMINUTE ranges from 0 minutes to 59 minutes. The scheduling interval must not be less than 1 hour. A maximum of 24 time points are allowed in a day. For example, if the scheduling time is 14:00 (UTC time) from Monday to Sunday, set the scheduling rule as follows: FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR,SA,SU;BYHOUR=14;BYMINUTE=00. For example, if the time of an area is UTC+8. The scheduling is performed at 14:00 every day in this area. The value of FREQ is the same as that of 14:00 minus 8. The rule is as follows: FREQ=DAILY;INTERVAL=1;BYHOUR=6;BYMINUTE=00.
