METHOD FOR ORGANIZING TELEPHONE SERVICE IN ISDN

The present invention relates to a method for providing a telephone service in an Integrated Services Digital Network (ISDN), as defined in the preamble of claim 1, wherein the method transmits a predetermined service request from a subscriber's ISDN via a public ISDN to a service provider's ISDN.

A method for arranging a telephone service in a public telephone network is known in the prior art, wherein a predefined service request is transmitted in the telephone network from the analog subscriber terminal of the service subscriber, such as a telephone, to the analog terminal of the service provider. An example of such a method is the current analog emergency telephone. For example, the phone of a person living in a retirement home has a hotkey to press for help in case of a sick scene. The service provider 20 (the alarm center) is provided with the subscriber number of the service subscriber (a person living in a retirement home) whose ·; identifies the service subscriber, after which the service provider can take the necessary steps.

As regards the features of the present invention, reference is made to the claims.

In the method of the present invention, the telephone service is provided using a public ISDN network. The public ISDN network includes a telephone exchange which includes subscriber lines to which ISDN terminals, such as ISDN telephones, are connected. The service request is transmitted from the ISDN terminal of the service subscriber through the public ISDN network to the ISDN terminal of the service provider 10. The service request is a predefined text message that is sent to the ISDN terminal of the service provider. The ISDN terminal subscriber number (service number) of the service provider is also predefined.

An advantage of the present invention over the prior art is that a predetermined text message containing additional information is transmitted to the ISDN terminal of the service provider instead of only the ISDN terminal subscriber number of the 20 service subscribers being transmitted to the ISDN terminal.

Since one or more different service requests are pre-stored on the ISDN terminal of the service subscriber, ... each of which separately determines to which service provider's ISDN terminal it is forwarded, the service subscriber's ISDN terminal implements a wide range of services. In addition, a pre-stored service • • * ·· service request ensures that correct information is transmitted in the event of an alarm, as errors due to haste are eliminated.

30 In one embodiment of the method, a UUS additional service (User-to-user sig- * * “'· nailing, UUS) as defined in the European Telecommunication Standard (" ETS ") is used to send a service request. ) implicit service 1. The service request is then transmitted as a text message in the UUI information element of the SETUP message [",

went, UUI). A SETUP message is a message from an ISDN signaling system that initiates call setup and transmits the information needed to establish a call. The UUI is an information element that transmits a maximum of 128 octets of information from one ISDN-5 user to another. The information is transferred from user to user as is, without modifying the content.

In one embodiment of the method, the ISDN terminal subscriber number of the service provider is transmitted in the Called Party Number information element of the SETUP message as defined in ETS 300 102-1.

In one embodiment of the method, the service request and the subscriber number of the service provider are pre-stored in the ISDN terminal of the service subscriber.

In one embodiment of the method, there are one or more service requests 15 and the like from the service provider's subscriber number.

In one embodiment of the method, a service request is transmitted by pressing a shortcut on the ISDN terminal.

20 In one embodiment of the method, a service request job is acknowledged to be received by a ISDN provider - <<<; terminal.

The invention will now be described, by way of example, with reference to the accompanying silicon, in which: Fig. 1 shows an embodiment of the method "·" according to the invention.

Figure 1 illustrates, by way of example, a method according to the invention applied to the elderly and disabled safety service. Here, the service subscriber is a person living in a retirement home whose various service requests in the form of SMS messages and the service numbers to which each message is forwarded are stored on the ISDN telephone. A predefined message is transmitted to the service provider with a single keypress. A person living in a retirement home asks for help from the retirement home service-10 points, for example, for a visit to the toilet, by pressing 1 hotkey predefined on their ISDN phone. The service request is transmitted as a text message via the telephone exchange 2 to the ISDN telephone 3 of the service point, where the caller acknowledges receipt of the service request and sends assistance to the service subscriber.

The method can also be applied, for example, to ordering a taxi without an actual voice call. The ISDN telephone 1 of the service subscriber has a shortcut key 20 for which a text message containing the address and time of the subscriber is defined and the service number is defined as a taxi center. To subscribe to a taxi service .., the subscriber presses the shortcut key. The message is forwarded to the taxi system from which it is automatically assigned to the nearest taxi based on the address of the service subscriber. When the request is received and accepted, the taxi system sends an acknowledgment including, for example, the taxi number.

Figure 2 illustrates, by way of example, a van-j *. #> 30 ISDN telephone 1 of a residential home.

Each shortcut on the phone 1 has a predefined service request and a service number to which the request ** '* · is forwarded. This provides a wide variety of services. For example, the 35 ISDN telephones of a person in a retirement home have a hotkey 2 for a heart attack. This will send a message to the alert center containing a heart attack notification 5 104454 and the address for which an ambulance is required. Since you only need to press one of the predefined hotkeys in the event of a sick scene, the ambulance alert is fast and smooth. In addition, the same ISDN-5 phone has, for example, a hotkey 6 for ordering lunch. In this case, the message will be forwarded to the retirement home service center and will include the lunch request and the apartment number. Further, a shortcut key 9 for shopping is defined. In this case, a home delivery agreement has been concluded with the Middle 10 stores. The message is conveyed to the home delivery service number and contains the subscriber's information and what goods the subscriber wants according to the pre-agreed shopping list.

Fig. 3 shows, by way of example, a signaling diagram of a method according to the invention. My service provider presses his ISDN telephone 1 hotkey from telephone 1 to send a SETUP message containing a Called Party Number (CLD) information element containing the ISDN telephone subscriber number 3 and having a 20 User-user (UUI) information element requesting a service request via SMS, with a maximum length of iiite · 128 octets. The message is transmitted to the telephone exchange 2, I «... which transmits it based on the CLD element to the ISDN phone of the service provider <i '·' 3. When the SETUP message arrives at 25, the service provider phone sends an ALER-TING message which is transmitted by the central 2 to the service subscriber • 1 • '·· . In this case, the service subscriber's phone will emit an alarm tone. When the service provider notices an incoming message, it is acknowledged. Acknowledgment is effected by sending the r 30 call termination message DISCONNECT, whose UUI element contains the acknowledgment as a text message. The exchange 2 transmits the DISCONNECT message to the service subscriber's telephone 1, after which the connection is terminated.

The invention is not limited only to the above exemplary embodiments, but many other modifications are possible, subject to the requirements of Claim 104,454.
