Abstract
A mobile communication system capable of efficiently updating software in a group of target terminals only when the software needs to be rewritten. When there is a mobile terminal (UE#, UE#) that needs the update of the software version, the server transmit an OTASP request that contains terminal type and software version information to GGSN. The OTASP request is forwarded via the GGSN, SGSN, and RNC to the mobile terminal (UE#, UE#). The mobile terminal (UE#, UE#) compares its type and software version with those contained in the paging channel, and if they match, transmits an RRC connection request to the RNC.
