SHORT MESSAGE SERVICE SERVER AND METHOD IN PRIVATE MOBILE NETWORK INTERWORKING WITH PUBLIC LAND MOBILE NETWORK

摘要

PURPOSE: An SMS(Short Message Service) server and method in a private mobile network interworking with a PLMN(Public Land Mobile Network) is provided to improve the SMS message transmission success rate for a mobile terminal subscribed in both a PLMN and a private mobile network. CONSTITUTION: An SMS server comprises an SMSC(SMS Control) module(304) and a public daemon(316). In case that a response indicating that a pMSC(private Mobile Switching Center)(120) failed in transmitting an SMS message is received, the SMSC module(304) appoints the type of the transmission-failed SMS message to a preset public SMS message type and stores it in an SMSC message queue(306). The public daemon(316) searches the SMSC message queue(306) to check whether an SMS message of the public SMS message type exists. In case that an SMS message of the public SMS message type exists, the public daemon(316) transmits an SMS request to the SMS server of a PLMN system through an IP network for the public SMS message type SMS message.
