Abstract

The invention relates to a process in a telephone system for the connection of mobile subscriber stations which are called from permanent stations, a call-back requirement being indicated at the mobile station. The object to be achieved is to make the call-back user-friendly. The object is achieved by providing the mobile station with memories which contain the identification code of the exchange and of the mobile station and which record the address of a fixed originally calling station. If a desired call-back is indicated at the mobile station, this can take place simply, by for example the push of a button. The identification codes of exchange and mobile station and the address of the permanent station are sent out automatically one after the other. This process may be used in the case of radio cars integrated in stationary telephone networks.

Description

Method in a telephone system for connecting

mobile subscriber terminals.

The invention relates to a method in a telephone system for Connection of mobile subscriber terminals, in particular via radio links connected mobile subscriber stations with storage facilities at a central location are provided by all fixed users after choosing a subscriber number a mobile terminal can be achieved, with a storage space for Callback from the called mobile subscriber station necessary to establish the connection controlling information is stored and continues with the call to called mobile subscriber station the subscriber number of the calling stationary Transferred subscriber station to the mobile subscriber station and in an existing one there Memory is saved.

In the case of the aforementioned telephone systems, it is known (The mobile paging service starts up in Sweden - TELE 30 1978/1, pages 4 to 7) that in the communication system both a wired network and a radio network to the central fixed Storage device of the telephone system are connected that this storage device is used to handle both incoming and outgoing connections from the radio network to build in the wire network and vice versa and that with a mobile subscriber terminal a memory device is also provided, which stores the when an incoming Call from the stationary central facility with transmitted subscriber number of the calling subscriber, with several subscriber numbers in succession can be saved by calling subscribers.

The mobile subscriber can then select an identifier, for example to reach the fixed central point, by choosing its identifier and by Choice of the subscriber number displayed by a calling subscriber build up.

The object of the invention is now to be the structure of a make such a connection much more user-friendly.

The solution to the problem is that in one of the mobile Subscriber station based on an existing call sign, for example, only the connection to the calling stationary subscriber station is automatically established by pressing a button is by using its own identifier permanently stored in the memory of the mobile station and the subscriber number of the fixed subscriber station now from the mobile Subscriber station are transmitted to the central point.

This has the advantage that when there is a call sign at the mobile subscriber station, a reverse link is established simply by pressing a button can be set up to the originally calling stationary subscriber station.

An advantageous further development of the invention consists in that the subscriber number of a stationary calling subscriber after storing into the memory of the mobile subscriber station there by e.g. pressing a Switching element can be made visible on a display and that when storing several Subscriber numbers of calling stationary subscriber stations in the memory of the mobile Subscriber station by continuously pressing the switching element one after the other all stored Participant numbers are visible on the display in an endless cycle and that for example, when the actuation of the switching element is finished, a connection to of the subscriber station with the last visible subscriber number can.

This has the advantage that the subscriber to the mobile Subscriber station can recognize which fixed subscriber stations his station want to reach and he can call the most important person waiting for him Select participants.

An advantageous further development of the invention consists in that in the memory of the mobile subscriber station other than its own identifier Identifiers for subscriber services - for example, call to the central office for the purpose of Request for a message left behind are permanently stored at Pressing a corresponding button to establish a connection are sent out.

This has the advantage that also only by pressing a single button or a switching element intended for mobile subscriber stations interesting subscriber services can be used.

The method according to the invention is explained in more detail below.

It is assumed that a wired telephone network with a fixed telephone exchange and a Radio network exist and that subscribers from one network in the other network to subscriber terminals connected there in particular subscriber stations via the fixed telephone exchange a connection can build up. For this purpose, both in the telephone exchange and in the mobile, the radio network associated subscriber stations memory units provided.

For example, a participant in a fixed station wants one Reach the paging subscriber, then he will first contact the fixed telephone exchange tied together. His station is identified there and that of this subscriber station assigned subscriber number as well as the selected subscriber number of the desired Pager stored. With the help of the subscriber number of the paging station a call connection to the mobile paging station in a known manner via the radio paging network Way built. The subscriber number of the stationary, transmitting the calling subscriber station and in a memory at the mobile subscriber station saved. Has the subscriber at the mobile station recognized the call and wants to if he set up the connection to the calling stationary station, then he just pressed a button, which automatically uses the permanently stored identifier to reach the stationary control center, the permanently stored identifier of the own mobile station and the subscriber number previously saved from the headquarters of the originally calling stationary station is sent out. In the fixed headquarters a scan of the memory contents and with the same memory contents as the incoming one Information (identifier of the mobile station + subscriber number of the calling station) a connection is switched through from the mobile station to the original one calling and waiting subscriber station or to a letterbox in the local firm central point from which a recorded message left there is retrieved can be.

A display can be provided on the mobile subscriber station which by pressing a switching element the subscriber number of the calling Participant station shows. By pressing the switching element again, the indication on the display and at the same time the corresponding subscriber number deleted in memory.

The memory at the mobile subscriber station can be designed so that of several stationary subscriber stations calling one after the other, the individual Subscriber numbers are saved. These individual participant numbers are included in Actuate the switching element one after the other for a certain time in an endless manner cycle shown on the display (e.g. with 3 waiting participants: 1. 2. 3. 1. 2.). In this way, the subscriber at the mobile station can choose which one is waiting with Participant he wants to connect first (or with which mailbox). Completed he actuates the switching element when showing the subscriber number of a particular one Participant, his participant number will remain on the display and when you press the button to establish a connection, the corresponding stationary Station established the connection.

The participant number is shown both on the display and in the Memory cleared.

In the same way, the subscriber at the mobile station with the Proceed with the other stored subscriber numbers.

Does the mobile subscriber want a stored subscriber station no connection or does he want to the station from a stationary one Call from the phone, then you can use your own deletion device to delete the stored Participant number be provided.

To simplify the operation of the mobile subscriber station, additional Keys may be provided, when they are actuated, permanently stored a respective one Identifiers assigned to subscriber service with the station's own identifier and the identifier be sent out to reach the fixed central point. This is the case, for example for the query of any messages left for the callback request of a permanent participant, etc.

From the above it can be seen that with the help of the invention The process of operating a mobile radio receiving station is much easier can be designed.
