BRIEF SUMMARY
BACKGROUND OF THE INVENTION

Field of the Invention
The invention relates to a method for accomplishing a register recall from a subscriber unit of a radio system providing a wireless local loop (WLL) and further relates to a subscriber network element for transmitting telecommunications signals between the subscriber units and the Public Switched Telephone Network (PSTN),
The invention also relates to a WLL system, that is, a radio system providing a wireless local loop, in which system the subscriber units are connected by a radio connection via base stations and a subscriber network element the PSTN.
Subscribers of the WLL system should have access to a register recall and subscriber facilities required thereby in the same way as the subscribers of a normal wired network. Also in the case of a loop dialling telephone, the restrictions for use should also be similar to those for subscribers of a wired network, that is, of the subscriber facilities requiring a recall only trace is operative.


SUMMARY OF THE INVENTION

The object of the present invention is to provide a register recall and subscriber facilities to subscribers of the WLL system. This objective is achieved through the configuration of the WLL system. The WLL system includes a subscriber network element and base stations to transmit telecommunications signal between the subscriber units and the PSTN. In this configuration, the subscriber unit refers to the equipment the subscriber has for transmitting and receiving telecommunications signals. The subscriber unit includes a terminal equipment connected to a user interface. The terminal equipment houses a radio part and a teleadapter. Any conventional type of user interface such as a telephone, a telefax terminal, a computer/modem combination or the like, can be connected to the WLL system by means of the terminal equipment, the radio path thus being invisible to the user. In a conversation state, the subscriber unit transmits a register recall frame to the subscriber network element via the base stations. The subscriber network element is in a standby status waiting to receive the frame and the dialing input. Once the frame and dialing input is received, the subscriber network element transmits the data on a speech path between the subscriber network element and the PSTN;
The invention is based on the idea that the register recall and the facilities can be provided in a simple and fast manner The a recall frame and dialing input are transmitted from a subscriber unit on a speech path, transmitted by a subscriber network element, to the fixed telephone network exchange so that the dialling in connection with the register recall frame can be analyzed at the exchange and the subscriber network element does not need to be able to analyze the dialling. The method of the invention is thus making use of features already existing in fixed telephone network exchanges. The most significant advantage of the method of the invention is that the register recall and the facilities can be provided to subscribers in a simple and reliable way without making any new requirements on the features of the subscriber network element or without raising the price significantly.
The invention also relates to a subscriber unit with which the method of the invention can be applied. The subscriber unit of the invention includes the terminal equipment that contains a means for transmitting a register recall frame to the subscriber network element in response to a recall signal transmitted from the user interface, and a means for transmitting dialing input from the user interface on the speech path to the subscriber network element after receipt of a standby message.
The invention further relates to a subscriber network element with which the method of the invention can be applied and which is suitable to be used in connection with the subscriber unit of the invention. The subscriber network element includes a means responsive to a recall frame transmitted by a subscriber unit. frame, exchange and speech path to the fixed t
