摘要:
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.

The invention relates to a radio system realizing a wireless subscriber interface, the system including a subscriber station (1) which comprises means (8, TRX) for forwarding, on the radio path, a supervisory signal received on the radio path, a base station (5) which monitors the connection to the subscriber station by means of the supervisory signal, and a subscriber network element (6) for transmitting communication signals between a communication system (PSTN) and the subscriber station (1). In order to transmit charging information, the subscriber network element (6) comprises detecting means (9) for detecting a home metering pulse transmitted from the communication system (PSTN), whereby the control unit (11) is arranged to control the supervisory means (10, 14) for sending a charging signal to the subscriber station (5) by means of the supervisory signal in response to detecting the home metering pulse, and the subscriber station (1) comprises a detecting means (12) for detecting the charging signal, and a signal generator (13) responsive to the detecting means (12) for generating and feeding a home metering pulse to the user interface (2) in response to detecting the charging signal.

A subscriber network element of a radio system provides a wireless local loop for transmitting telecommunication signals between subscriber stations and an exchange. To enable a register recall, the subscriber network element comprises a timer, a buffer arranged to buffer dialing frames, the timer being arranged to start measuring a new time interval upon reception of each dialing frame, and a control unit arranged to transmit a stand-by message and a register recall message, and to initialize the timer to measure a time interval of a predetermined length in response to the register recall frame, and to forward a "dialing received" frame and any digits buffered in the buffer as the time interval measured by the timer elapses.

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).

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 (5) is defined as a specified geographic area comprising the coverage area of at least one cell (4), 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.

In a method and system for recovering a faulty unit, a predetermined number of recovery periods, and the maximum number of times a recovery act is carried out during a recovery period, are defined. A faulty unit is taken out of operation, recovered (i.e. subjected to a procedure designed for remediating the fault, if possible), and brought back into operation if tests indicate that the unit is in condition (i.e., is not faulty). The recovered unit is monitored for the time of succeeding recovery periods and is re-recovered, if necessary, provided that the number of the recovery acts carried out during each recovery period does not exceed the maximum number predetermined for the respective period. As a result, bouncing of the unit back and forth in an uncontrolled manner, if the fault is of such a type that the recovery system cannot detect it on the basis of the tests carried out, is reduced and eventually curtailed.

The invention relates to a method for accomplishing a register recall from a subscriber unit of a radio system providing a wireless local loop, the radio system comprising a subscriber network element and base stations to transmit telecommunication signals between the subscriber units and a public switched telephone network. To obtain a register recall in a simple and fast manner, a register recall frame is transmitted from the subscriber unit in a conversion state of the unit to the subscriber network element, a message is awaited from the subscriber network element about receiving the frame, and diallings input from a user interface of the subscriber unit are transmitted on a speech path via the subscriber network unit to the public switched telephone network. The invention also relates to a subscriber unit and a subscriber network element.

The invention relates to a method for transmitting tariff data via radio-frequency signals to a chargeable subscriber unit (1) communicating with a telecommunication network (7). In order to charge the user of the subscriber unit as fairly as possible, a tariff frame corresponding to a lump sum is transmitted to the subscriber unit (1), charge-metering signals received from the telecommunication network (7) are counted, and when the monetary value corresponding to the number of the counted charge-metering signals exceeds a predetermined threshold value, a new tariff frame corresponding to a lump sum is transmitted to the subscriber unit (1). The invention also relates to a system where the method according to the invention can be applied.
摘要:
In a method of monitoring the operation of a subscriber unit in a telecommunication system, in order to detect possible malfunctions as early as possible, a call reserved in signaling for some other purpose is transmitted to the subscriber unit, whereupon a call to which the subscriber unit automatically responds is selected as the call. A message about receiving the call is awaited from the subscriber unit, and, if not such message is received from the subscriber unit, the call is repeated until the subscriber unit has left a predetermined number of transmitted calls unanswered, whereupon an alarm is given.

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.
