Definitions

  • the invention relates to a method for indicating the charge of a call.
  • radio link allows subscribers to roam freely within the area of the entire network and even from one national network to another as, for example, in the new pan-European digital mobile phone system GSM.
  • GSM new pan-European digital mobile phone system
  • a Finnish subscriber may be travelling in England and communicate with the system through the national network of England. If another Finnish subscriber then tries to contact the subscriber who is in England, the call must be routed from Finland to England through the networks of e.g. Sweden and Norway, whereby the charges of all of these networks will be added to the charge of the call. The charge of the call can thus be rather high, which may be a surprise to the subscriber if he is not prepared for it.
  • a calling subscriber for example, would usually like to know in advance how much he will be charged for the call; this he would only find out if he knew the location of the called subscriber.
  • most sub- scribers do not want just anybody to be able to find out their location, not even approximately, and therefore the present systems have adopted the principle that the charge to be collected from the calling party is inde ⁇ pendent of the actual location of the called party. Charges due to the roaming of the called party are collected from the called party.
  • the called party does not know in advance, either, where the calling party is located and thus cannot estimate the charge of the call.
  • the current cellular networks offer a so-called advice-of-charge service, by means of which the charge of a call can be indicated in real time on the subscriber station. It has become more and more usual to attempt to apply radio technology even to the area of a conventional public switched telephone network, i.e. to replace a so-called fixed cable with a radio link. Before long, the roaming of subscribers will be possible even in a public switched telephone network. The subscribers of a telephone network using fixed links are not necessarily used to this, which will be a problem. The charge of a call or the unit charge may be higher than what the subscriber is prepared for.
  • An object of the present invention is to give the subscribers better chances to influence the charge of a call in advance.
  • Another object of the invention is to allow the charge of a call to be more flexibly divided between A- and B-subscribers.
  • the basic idea of the present invention is that the subscriber who will be charged for a call is informed of the charge of the call in advance, before the link to another subscriber is even established.
  • the advice-of-charge service according to the invention is a subscriber-specific service, which the subscriber may activate either permanently or separately for each call.
  • a subscriber who has an activated advice-of-charge service wishes to set up a call, he performs normal dialling, and the number dialled by the subscriber is transmitted in the normal manner over the radio path to the fixed network.
  • the network estimates the total charge, unit charge (Mk/min) or charge level of the call, of which information is sent to the sub ⁇ scriber either in each case or according to certain criteria.
  • the call set-up will not be continued until the subscriber gives his permission to do so by a specific acknowledgement message. At this stage, the radio network and the fixed network do not allocate any resources. If the subscriber rejects the call and does not send an acknowledgement message, the call set-up is terminated.
  • the advice-of-charge service was described from the point of view of the A-subscriber.
  • the B-subscriber may also wish to be provided with the service according to the present invention.
  • an estimate of the total charge, unit charge or charge level of the call is sent to the B-subscriber before the call is set up, and thus the B-subs ⁇ riber is given the possibility of not to accept or receive the call if he finds it too expensive.
  • the estimation of the charge of a call can, in principle, be based on two criteria:
  • the first alternative is thus based on knowledge of the exact charge, calculated by time, whereas according to the second alternative, the subscriber is informed only of the tariff level of the call, e.g. low/high.
  • the tariff level is more easy to determine in real time and to give to the user for con ⁇ sideration before the setting up of the call is continued.
  • a blocking function will be activated in the subscriber data.
  • the fixed network will not continue to set up a call even if it receives an acknow- ledgement message from the subscriber if the estimated call charge or the charge level is not within the range of charges set for the subscriber by the blocking function.
  • this is such an advice-of- charge service according to the invention where the termination of call set-up can under no circumstances be avoided.
  • companies can restrict the use of the mobile stations of their employees to a certain service area.
  • the invention also relates to a subscriber station comprising a display, number keys and function keys.
  • the subscriber station is characterized in that the subscriber station indicates the call charge information received from the telecommunications network on a display, and that a user may activate the subscriber station by said function keys to send an ac ⁇ knowledgement message to the telecommunications network in order to continue the setting up of the call.

According to the invention, this is achieved by inform ⁇ ing the subscriber of the charge of a call in advance, before the link to the other subscriber is established, i.e. before any charges are incurred. On the basis of the call charge information, the subscriber can either accept or reject the call. In principle, the charge estimate given to the subscriber may be based on either a real-time call charge information, e.g. the unit charge in the case of charging by time (e.g. dollars/min) or relatively rough distinction between tariff levels.

  • the MSCl receives a call set-up request 1 selected by the A-subscriber.
  • the MSCl sends a request 2 concerning the subscriber parameters of the A- subscriber to the local visitor location register VLRl.

  • the HLR knows the current visitor location register VLR2 of the B-subscriber.
  • the HLR sends a roaming number request message to the VLR2, which sends the roaming number in its response 6.
  • the HLR sends to the MSCl a message 7 comprising the roaming number and the identifier of the current visitor location register VLR2 of the B- subscriber.
  • the MSCl checks whether the call will be a low or a high tariff call. This can be determined, for example, by comparing the current address (VLRl, MSCl) of the A-subscriber with the B- subscriber's roaming number (VLR2), obtained from the HLR.

  • the MSCl can use this data for determining the tariff class of the call. If both the A- and the B- subscriber are within the same network and thus within the so-called low tariff area, the MSCl does not interrupt the call set-up and does not send a charge information message to the A-subscriber MS A .

If the user accepts the call, he sends an acknowledgement message 9 to the exchange MSCl, whereafter the MSCl begins again to set up the call in the normal manner. If the A-subscriber does not accept the call on account of its high charge, he does not send an acknowledgement 9 or sends a negative acknowledgement, whereafter the MSCl permanent ⁇ ly terminates the call set-up.

Abstract

L'invention concerne un procédé de communication de la tarification d'un appel dans un réseau de télécommunications. Dans le procédé selon l'invention, l'abonné auquel l'appel sera facturé est informé à l'avance de la tarification de l'appel, avant que la liaison soit établie avec l'autre abonné. Lorsqu'un abonné (MSA) souhaite passer un appel, il effectue une numérotation normale, et les données numérotées par celui-ci sont transmises normalement (1) au réseau fixe (BSS; MSC1) par la voie radioélectrique. Selon l'endroit (213) où se trouve l'abonné appelant et/ou appelé, le réseau évalue la tarification totale, la tarification unitaire (Mk/min) ou le niveau de tarification de l'appel, ces informations étant ensuite envoyées à l'abonné à chaque fois ou en fonction de certains critères. Si les informations relatives à l'appel sont envoyées (4) à l'abonné, l'établissement de la communication sera interrompu jusqu'à ce que l'abonné donne la permission de continuer par un message d'accusé de réception spécifique (5). A ce stade, le réseau radioélectrique et le réseau fixe n'attribuent aucune ressource. Si l'abonné rejette l'appel et n'envoie pas de message d'accusé de réception, l'établissement de la communication est stoppé. L'invention concerne également un poste d'abonné à utiliser pour ce procédé.
