Abstract: In a Short Message Service (SMS) between private wireless network systems in a multi-zone arrangement, when private wireless network systems, which have been separately placed, are configured in one service area called a multi-zone arrangement, Home Location Register (HLR) information is periodically updated and synchronized through interfacing between the private wireless network systems in the multi-zone arrangement, and making it possible to determine whether or not a receiving terminal is positioned in a service area of which of the private wireless network systems using the synchronized HLR information. An SMS transmission is requested to a call processor of the associated private wireless network system to allow performing SMS message transmission to the associated terminal.

Abstract: A server and method for a short message service (SMS) that can improve the chances of success in short message service message transmission to a mobile communication terminal subscribed in both a public land mobile network (PLMN) and a private wireless network in an interworking system where the public land mobile network and the private wireless network interwork with each other. The short message service server transmits a message according to a request through an Internet protocol (IP) network to a private mobile switching center (pMSC) of a private wireless network system, and if there is a response indicating a failure of the transmission received from the private mobile switching center, designating the failed message as a predetermined public short message service message type, storing the message of the public short message service message type in a message queue, and requesting the short message service to a server of a public land mobile network system through the Internet protocol network.
