Abstract: PURPOSE: A method for limiting mobility in a mobile network is provided to constrain the mobility of mobile subscribers in cell units so as to accept fix-typed mobile subscribers and closed group subscribers using an existing mobile network and ensure mobility of terminals and service differentials. CONSTITUTION: A home location register(HRL) registers admissions on cells having cell IDs on a subscriber database in geographic forms. The HLR registers ID lists including market IDs and cell IDs. Both of the IDs are contained in an area where subscribers can receive services. A base station(BS) transmits a location register signal to a mobile station center(MSC) and requires a location updating. The BS transmits the location register signal to a visitor location register(VLR). The VLR transfers the location register signal to the HLR. The HLR decides whether geographic authorization(GA) forms are admission on cells having the market IDs. If so, the HLR compares the cell IDs with the market IDs to decide whether both of the IDs are equal. If so, the HLR transmits a GA responding to the location register signal to the VLR, in reference to the admission on the cells having the market IDs. If the transmitted GA is the admission on the cells having the market IDs, the VLR stores the GA and the cell ID of the location register signal in a subscriber database. The VLR performs a location register signal corresponding to the MSC. The MSC transfers a location register success signal to the BS.
