Information broadcasting method and system

A monitoring information broadcasting device, comprising:

• a hardware processor;
• a memory storing program codes that, when executed by the hardware processor, cause the hardware processor to:
• determine a series of transmission sessions aligned to a system time of a mobile platform, each transmission session including a first time period and a second time period, the first time period including a plurality of first time slices, and the second time period including a plurality of second time slices, and
• generate an instruction for broadcasting information during the transmission sessions, the instruction instructing to broadcast:
• a data packet of a first type during a first active slice among the first time slices in the first time period of one of the transmission sessions, or
• a data packet of a second type during a second active slice among the second time slices in the second time period of the one of the transmission sessions;
• and
• a transmitter configured to broadcast information according to the instruction.

A monitoring information broadcasting method comprising:

• determining, by a hardware processor, a system time for a mobile platform according to a timing signal;
• determining, by the hardware processer, a series of transmission sessions aligned to the system time, each transmission session including a first time period and a second time period, the first time period including a plurality of first time slices, and the second time period including a plurality of second time slices;
• broadcasting, by a transmitter mounted on the mobile platform, a data packet of a first type during a first active slice of the first time slices in the first time period of a first one of the transmission sessions;
• broadcasting, by the transmitter, a data packet of a second type during a second active slice of the second time slices in the second time period of a second one of the transmission sessions;
• and
• suspending broadcasting during inactive ones of the first time slices in the first time period of the first one of the transmission sessions, the second time period of the first one of the transmission sessions, the first time period of the second one of the transmission sessions, and inactive ones of the second time slices in the second time period of the second one of the transmission sessions.
