摘要
Instant messaging is a basic wireless service of mobile network. The system on the basis of DTU, sends the collected data by short message to supervision center, so the system can carry out wireless data transmission. The paper introduces structure of wireless data transmission system, describes a instant messaging system framework design based on the CDMA network, function module and its designing idea and the key database. The cost of the instant messaging system is small, constructing investment small, maintenance, circulate expenses low.
