LONG MESSAGE SERVICE SYSTEM USING AN ASYNCHRONOUS WIRELESS COMMUNICATION NETWORK AND A METHOD THEREFOR, CONCERNED WITH PREVENTING TRANSMISSION DELAY OR A LOSS OF DATA

摘要

PURPOSE: A long message service system using an asynchronous wireless communication network and a method therefor are provided to prevent transmission delay or a loss of data by transmitting a long message to a mobile communication network without going through an SMS center. CONSTITUTION: A user creates a long message and sends it(510). A BS(Base Station)(120) receives the long message transmission signal, converts it into mobile communication data and transmits long message transmission data to an MSC(Mobile Switching Center)(130)(S520). The MSC(130) establishes a mobile communication path with a different MSC(230) and an official switching path with an IWF(Inter-Working Function)(242) and then transmits the long message transmission data to the IWF(242)(S540). The IWF(242) converts the mobile communication long message transmission data into line long message transmission data and sends it back to the MSC(130)(S550). The MSC(130) transmits the line long message transmission data to the MSC(230)(S560). The MSC(230) establishes an official switching path with the IWF(240) and transfers the line long message transmission data to the IWF(240)(S570). The IWF(240) converts the line long message transmission data into mobile communication long message transmission data and then transmits it to the MSC(230)(S580). The MSC(230) transmits the mobile communication long message data to the BS(220), and then, the BS(220) transmits it as a radio signal to a mobile terminal(212) of a receiver(S590).
