Definitions
- a subscriber station refers to the equipment that a user has at his disposal for transmitting and receiving telecommunication signals.
- a subscriber station includes a WLL terminal equipment, which consists of a radio section and a teleadapter (to which a user interface such as a telephone is connected), and a user interface connected to the terminal equipment, i.e. a telephone, telefax, computer/modem combination or similar.
- an off-hook state is used to refer to a state which is created when for instance a phone user lifts the receiver to make a call.
- the subscriber station of the WLL system is arranged to continuously listen to the calling channel of the radio system in order to detect calls possibly directed to the subscriber station.
- the subscriber station In disturbance situations, when the subscriber station does not hear the calling channel of the radio system, the subscriber station must be able to signal the created disturbance situation to the station user. Since any telephone set adapted to be used in the public telephone network can be used as a user interface in the WLL system, the signalling of a disturbance situation must be such that it requires no special characteristics of the user interface.
- the figure shows a subscriber station 1, which comprises a telephone 2 and a terminal equipment 3.
- the telephone 2 shown in the figure is a conventional telephone that can be connected to the public telephone network. Instead of the telephone 2, it is possible to use quite as well some other user interface such as a telefax or computer/modem combination in the system shown in the figure.
- the telephone 2 and the terminal equipment 3 are connected by a two-wire line 4, via which signals can be transmitted between the terminal equipment and the telephone.
- the terminal equipment 3 comprises signal processing means for fitting a speech path onto the radio channel.
- Signal processing means of this type are for instance a radio section, which comprises an antenna 8, a radio transmitter and a radio receiver, and a teleadapter, which adapts the radio section for the conventional telephone 2.
- the subscriber station 1 communicates with a base station 5 (three base stations BS are shown in the figure) with radio-frequency signals via the antenna 8, calls being transmitted via this base station to a subscriber network element 6 and further to the PSTN (Public Switched Telephone Network), i.e. to a fixed telephone network 7.
- PSTN Public Switched Telephone Network
- the base stations 5 correspond to the parts of the NMT-450i (Nordisk Mobil Switzerland) cellular radio system. As regards signalling, the subscriber station 1 thus operates like a conventional subscriber station of the NMT-450i system.
