[0002] In the currently used office network information transmission methods, usually direct network transmission and mobile short message service are used for information transmission after interconnection with the public network mobile communication system through the Internet, and FM voice broadcast and digital broadcast transmission are also used. Among them The disadvantages are: FM voice broadcasting is not storable, and it is not easy to consult at any time; the transmission method of digital broadcasting adopts the broadcasting method, so the encryption is poor, and it is impossible to transmit information to user groups and individual users; The mobility of the transmission method is poor, and the office network information cannot be transmitted to the user in a timely manner. However, the mobile short message service transmission needs to occupy mobile short message transmission resources, and certain expenses will be incurred during frequent transmission, especially in enterprises and institutions. The transmission of network announcement information on the office network of colleges and universities requires good mobility, storage and query, good encryption, multi-user grouping and individual transmission, and low-cost information announcements and notifications. The existing method is cannot meet the need
