PURPOSE: A method for announcing access to a specific service network in a mobile communication system and a manner mode transfer method are provided to notify an MS(Mobile Station) user that the MS is moving from a PLMN(Public Land Mobile Network) to a private mobile network. CONSTITUTION: A pBSC(private Base Station Controller)/pMSC(private Mobile Switching Center)(50) sets spare bits among a system parameter message and broadcasts them to a private network(102). An MS(40), if the system parameter message is received, searches the system parameter message for a bit indicating that the MS(40) has entered the private network. In case that the bit has been set, the MS(40) judges that the present location is within the coverage of a pBTS(private Base station Transceiver Subsystem)(104). Then the MS(40) transmits a location registration message to the pBSC/pMSC(50)(106). Receiving the location registration message, the pBSC/pMSC(50) requests a pHLR(private Home Location Register)(30) to send information for the subscriber(108). The pHLR(30) searches a subscriber database and transmits a result to the pBSC/pMSC(50)(110). The pBSC/pMSC(50) checks whether the subscriber is a subscriber registered in a private mobile network(112). In case that the subscriber is a registered subscriber, the pBSC/pMSC(50) sets an appointed field of an FNM(Feature Notification Message) and downloads it to the MS(40)(114). The MS(40), receiving the FNM, informs the user that the present location is within the coverage of the private mobile network(116).
