Abstract: PURPOSE: A roaming service method in a digital TRS(Trunked Radio System) is provided to equip VLRs(Visitor Location Register) in exchanges of each local service provider and equip an HLR(Home Location Register) in a central center, so as to perform message routing and registration control between the exchanges of the local service providers, so that high-quality nationwide network services without call disconnection can be provided to subscribers. CONSTITUTION: If a terminal serviced through an exchange of a digital TRS of a present local service provider moves to a service area of another local service provider, the terminal transmits a registration request message to a new local sector. The new sector transmits the registration request message to a CC(Central Controller) of the exchange. The CC searches whether SUID(SUbscriber IDentity) is registered in the CC. If the SUID is registered, an idle handover process is performed. If the SUID is not registered, information of corresponding SUID is requested to a VLR. If the information of the SUID is defined in the VLR, the idle handover process is performed. If the information of the SUID is not defined in the VLR, visitor ID for the SUID of the corresponding terminal is allocated and registered in the VLR, and new terminal registration is requested to an HLR of the central center. The HLR registers information on the corresponding terminal, and delivers a registration confirm message to an exchange CC of a new service provider, then transmits a registration cancel message to the CC of a prior service provider. The CC of the new service provider registers the new SUID, and registers the terminal at a new sector, to control the terminal to continuously perform services. The CC of the prior service provider cancels the registration for the SUID, and delivers a registration cancel message to a prior base station to cancel the registration of the terminal.
