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. That is, it allows an automatic SMS incoming operation at the associated private wireless network system using HLR database information updated periodically, without a separate request for position registration and specific option set by a user.

Short message service between private wireless network systems in multi-zone arrangement

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.
