Abstract

If a call-back occurs on the switchboard position of a telephone switching system, the required subscriber being able to be sought via a paging device or to be called via a radiopaging device, the call display on the switchboard position contains not only the telephone number of the required subscriber connection but also a corresponding indication of the search or call facility. Once the operator, having pressed the answer key, has then conveyed a corresponding message to the calling subscriber, the existing connection is cleared down by pressing a special key and the calling subscriber is connected to the paging or radiopaging device.

Procedure for centrally controlled telecommunications, in particular Telephone switching systems with operator stations

The invention relates to a method for centrally controlled telecommunications, in particular telephone switching systems Switching stations each with a display device, after which a connection to a subscriber line has been allocated if the subscriber is busy or if the subscriber does not answer, a recall is signaled at the operator console and the switching system has a customer data memory.

"ο Recall is understood to mean a process in which a call assigned to a subscriber by the operator console Call when the subscriber line in question is busy or when the subscriber does not answer after a specified period has elapsed Time is displayed again at the operator console. This means that the operator of the attendant console is in able to contact the calling subscriber. The procedures in the context of the recall are for example in the book by Oden, .Nachrichtenvermittlung, Oldenbourg-Verlag Munich / Vienna 1975 described on page 3o5.

The object of the invention now consists in specifying a method which can be used for further processing in a simple manner of a call as part of the recall, if the desired subscriber also has a people search system or a pager can be reached. '

This object is achieved in that on the display device the phone number of the subscriber connection concerned is displayed together with a note as part of the recall is that this participant can be reached via a person search device or via radio paging, the Note is generated from a corresponding authorization identifier of the customer data memory, and that by actuation a special key to initiate the search or call process in which the previous connection is triggered,

1o_ the calling subscriber with the person search facility or connected to the radio paging device and transmitted the number of the called subscriber to this device will.

^ 5 The information on the display means that the operator the operator's attention is drawn to the fact that the called subscriber also has a person search facility or a pager can be reached. All you have to do is press a special key to initiate further processes.

Although it is already known to initiate the connection of a calling subscriber to a person search facility through the switchboard (DE-OS? 9 ^ o 479 ) , a search code must be selected at the switchboard.

Further advantages result from the subclaims. 3o

The invention is explained in more detail using an exemplary embodiment which is shown in the drawing is.

The telephone exchange, such as a private branch exchange consists of a switching network K and peripheral devices connected to it, such as subscriber line circuits TS for connecting telephones T,

LS line circuits are not connected to the connection of connecting lines VL, 'space PS controls to connect switchboard positions P, a Paging or pager PT' and other facilities not shown, but with the invention. The peripheral facilities

and the switching matrix K are connected to a common control device ST. This communicates with the peripheral devices switching-oriented data, and causes the switching through connections within the ^"1 O switching matrix K.

The method according to the invention is based on a switching structure explained. It is assumed that a remote subscriber line is an exchange the connection line VL has occupied and with the subscriber set T want to be connected. The relevant connection line VL is first via the switching network K connected to a switchboard P, the operator of which the remote subscriber wishes to connect to notifies what the operator about the switching ' place P the switching through of a connection within the switching matrix K by the control device ST by input the number of the desired subscriber.

It is now assumed that the desired subscriber line TS is either busy or the subscriber is Does not answer the call. Due to the occupancy or after a specified time has elapsed, the Call at operator P automatically signaled again as a recall. It is now assumed that the desired subscriber is searched either via a people search facility or via a punt call facility can be called wirelessly. In this case, the customer data memory in the control device ST a corresponding authorization code in which the Subscriber line assigned to the called subscriber

Storage space included. As part of the Viederanruf will be from the control device to the attendant console P the call number of the called subscriber line and on from the notification derived from the authorization identifier, which together with the subscriber number is displayed on attendant console P. In this way, the operator of the operator will become away informed that there is another possibility to reach the desired participant. By actuation

^Λ ο .. the query button, the operator can contact the calling subscriber again and inform him that there is an opportunity to search for the subscriber or to call wirelessly.

^ 5 If this is requested by the calling subscriber, then click the operator of the attendant console presses a special button, whereupon the connection between the trunk line VL and the operator P triggered and instead a connection between the connecting line and VL the device PT is set up via the switching matrix K at the instigation of the control device ST. Also receives the device PT from the control device ST the call number of the called subscriber line. With the help of a Announcement device assigned to the device PT is, the calling party can be made aware that measures to search or wireless Calls have been taken.

In the case of people ^{searching devices, for example, a 3} So visual display can be carried out at a large number of locations where the called subscriber could be. "As soon as the called subscriber realizes that he is being called, he can establish a connection to the facility PT from any telephone set in the private branch exchange by dialing a certain number, whereupon himself-

■ & 0 COPY

active a connection with the relevant connecting line VL via the switching matrix K takes place. In the case of a radio paging device, either the subscriber's radio pager, which can be reached under the number of the desired subscriber, can be reached wirelessly by sending a certain combination of friends, with an optical and / or acoustic signal being generated when the pager carried by the subscriber speaks, whereupon the subscriber in turn has the option has to be connected to the calling subscriber via a telephone in the manner already described. However, it is also conceivable to set up a wireless voice connection between the device PT and the radio paging receiver, if it is provided for this purpose.

^ 5 If the call number of the pager is not identical with the call number of the subscriber line of the subscriber in question, a can within the facility PT appropriate implementation can be carried out with the help of a table. \

It has already been proposed to reduce the number of keys on the operator keyboard of an operator station to assign changing functions to some of the keys (corresponding to the "softkeys" of a data terminal), whereby the function of the individual keys depends on previous key presses, certain operating states the telephone exchange, etc., is changed. This principle can also be used within the scope of the invention are, in which depending on the actuation of the query button and the authorization identifier a specific key in this case the function is assigned that when you press the coupling of the connecting line SL to the facility PT and the transfer of the call number of the called subscriber to the same he follows.

It should also be noted that in the embodiment of a telephone private branch exchange shown in the drawing only one device is shown of each type of peripheral device at a time, though these are available in a multitude.
