1. A mobile communication system in which OTASP (Over The Air Service Provisioning) is performed to rewrite software in mobile terminals based on data transmitted via radio from a server, wherein:

  • the server includes a means for paging a target mobile terminal by transmitting thereto, when OTASP is to be performed, a request attached with information on the type of the mobile terminal and the version of the software; and

    the mobile terminal comprises;

    a means for determining, based on the information attached to the request, whether or not the data is to be multicast or broadcast to the terminal;

    a means for, when having determined that the data is to be multicast, transmitting a response to the request before receiving the data; and

    a means for, when having determined that the data is to be broadcast, receiving the data without transmitting a response to the request,wherein the server broadcasts the data repeatedly until a predetermined period of time has expired, and then immediately multicasts the data, andwherein the mobile terminal activates a timer upon initiation of OTASP data reception and if the OTASP data reception is complete before the timer expires, the mobile terminal updates version information of the software on the mobile terminal and if the timer expires before the OTASP data reception is complete, the mobile terminal discards OTASP data that has been received, terminates the OTASP data reception and sets version information of the software on the mobile terminal to a previous version.
