Procedure for the transmission of operation control functions in a telecommunication system comprising a local exchange, a user interface provided in the system, an access node connected to the local exchange via a V5 interface, a wireless local loop system connected to the access node and a terminal device connected to the access node via the wireless local loop system. In the procedure, the operation control functions are generated in the access node on the basis of input supplied via the user interface, and transmitted in the form of short messages directly from the access node to the terminal device.

Method for transmitting operation and maintenance functions in a telecommunications system

A telecommunication system for a register recall, said system comprising a local exchange (LE), an access node (AN) connected to the local exchange via a V5 interface, a wireless link system connected to the access node, and terminal equipment (MS) connected via the wireless link system to the access node. According to the invention, the system comprises elements (MS, AN) by means of which a request to set a current call into hold state is sent from the terminal equipment to the access node, a response message rejecting the request to set the current call into hold state is sent from the access node to the terminal equipment and a register recall request is sent from the access node to the local exchange.

Register recall in a will system

The present invention relates to a wireless local loop. In particular, the present invention relates to a procedure for limiting the mobility area of a terminal device in a wireless local loop environment. According to the invention, the mobility area (MOA) for the terminal device (,) is defined as a specified geographic area comprising the coverage area of at least one cell (,), and the locking of the terminal device with the local loop and/or channel change by the terminal device is inhibited if the cell from which the terminal device is trying to get locked or to whose channel it is trying to change is outside the mobility area.

Procedure for limiting the mobility area of a terminal device in a wireless local loop

The invention relates to a procedure for ensuring emergency calls in a wireless local loop environment which is based on technology employed in a mobile telephone system and which comprises a telephone exchange (,), an access node (,) connected to the telephone exchange, a terminal device (,) and a base station (,) connected to the telephone exchange via the access node and serving to transmit call signals between the access node and the terminal device, in which the home network (,) of the terminal device is defined by the base station and the associated access node and in which base stations (,) of other networks are disposed in the environment of the local loop, so that the terminal device receives information signals from the surrounding base stations and, based on said information signals, determines the base station it is communicating with, and the emergency call is set up via any base station compatible with the terminal device. To ensure successful set-up of an emergency call when connection between the terminal device (,) and the telephone exchange (,) of its home network (,) is lost, a dial tone is generated by means of the terminal device, an emergency number dialed via the terminal device is identified and the emergency call function of the mobile telephone system is used for the set-up of the emergency call.

Subscriber network element

The present invention relates to a method for establishing a telecommunication connection from a subscriber station (1, 9) of a radio system forming a wireless subscriber connection to a public switched telephone network (PSTN), in which method a call request is received from the subscriber station. For achieving a faster and simpler connection establishment than heretofore, a traffic channel is reserved from a data transfer channel (12) leading to the PSTN exchange (7) to be used by the subscriber station (1) that has sent a call request, a connection is established to the PSTN exchange (7), an acknowledgement message is sent to the subscriber station (1), and a speech path is connected between the PSTN exchange (7) and the user interface (2) of the subscriber station, whereby the sound signals fed by the PSTN exchange (7) are transmitted directly on the speech path to the user interface (2) of the subscriber station (1), and the diallings supplied from the user interface (2) of the subscriber station are transmitted to the PSTN exchange (7).
