Mobile based services for hotel PBX

摘要

A method for providing mobile based services within a hotel PBX, where each hotel room is provided with at least one mobile station (1a, 1b') comprising a SIM, each SIM storing a different IMSI number. A VPN (VPNH) is assigned to the hotel and each IMSI number of each mobile station (1a, 1b') is assigned a different MSISDN (MSISDNA, MSISDNB) that can only be used internally hotel network and that cannot be dialled from other telephones. Each MSISDN (MSISDNA, MSISDNB) is assigned to a different extension number (ExtA, ExtB) that can be used as a room extension number and that corresponds to the VPN number of the VPN (VPNH) of the hotel. The method allows calls from and to hotel mobile stations (1a) to be directed within the hotel network or onto the wider telephone network.
