Definitions

  • the present invention relates to the routing of calls in telecommunication networks and in particular to the routing of calls to a particular subscriber to the subscriber's present location.
  • PSTN Public Services Telephone Network
  • PC personal computer
  • a Universal Personal Telephone (UPT) number may be used. This, however, requires a subscription to the UPT service and a special number to be issued. The UPT number is normally not listed in the telephone directory, and is therefore hard to find. Also, a predetermined group of terminals are covered by the UPT number, and the user may add or remove terminals.
  • UPT Universal Personal Telephone
  • Patent application WHO 97/01918 describes a forwarding service, forwarding a call to one of several telephone numbers belonging to a subscriber, to the subscriber's mobile telephone if it is switched on.
  • This service uses a paging principle, that is, if it is not known where the subscriber is at a given time, a paging message is sent to all terminals. When the subscriber answers at any of the telephones, the call is connected to this telephone. There is, therefore a delay in the set-up of the call.
  • a method called precision paging is used. It is not described in detail, and is only mentioned in connection with mobile telephones.
  • a method in a telecommunication network in which a subscriber may be reached at more than one terminal, for connecting calls to the subscriber to the terminal at which the subscriber is currently located, said method comprising the following steps: - detecting the terminal at which the subscriber currently selects to be reached; - automatically setting a call forwarding function from the other terminals at which the subscriber may be reached to the terminal currently selected by the subscriber;
  • the call may be detected to an answering service or to a default terminal, or to the terminal to which calls were last connected.
  • More than one group of terminals may be specified, from which the calls are to be forwarded depending on the subscriber's choice at any given time.
  • a call forwarding agent adapted to register automatically for at least one first termi- nal at least one other terminal from which all incoming calls are to be forwarded to the first terminal, and a control node in a telecommunication network, comprising a call forwarding agent according to the invention are also disclosed.
  • one or more predetermined groups of telephone numbers from which calls are to be redirected may be specified, for example by letting each group of terminals be associated with a code.
  • one group may include all the numbers at which the subscriber may be reached for private purposes, whereas another group also includes the work telephone numbers.
  • the apparatus according to the invention is easy to operate, as all functions needed to redirect calls may be performed automatically, so that the subscriber need only, for example, lift the hook of the telephone to which calls are to be redirected, or turn it on, to effect the redirection.
  • the solution according to the invention will reduce the number of unsuccessful calls, and thus enable a more efficient use of the network resources.
  • Figure 1 is a schematic drawing of a telecommunications network according to the invention.
  • Figure 2 is a flow chart of the actions performed to redirect calls according to one embodiment of the invention
  • Figure 1 shows an overall telecommunication network comprising a PSTN network 1, a mobile telephony network 3, an ISDN network 5 and a business network 7. It will be obvious to the skilled person that this is only intended as an example. Of course, more than one network of the same kind may be used, as well as other network types such as data networks.
  • Different types of terminals are connected to the networks: A first 9 and a second 11 telephone are connected to the PSTN network 1.
  • a mobile telephone is connected, via a radio link, to the mobile telephony network 3, an ISDN terminal 15 is connected to the ISDN network 5, and a telephone 17 is connected to the business network.
  • a call forwarding agent 19 is located in the overall network, in such a way that it can be reached from terminals connected to all the networks 1, 3, 5, 7, as shown by the bi-directional connections between the call forwarding agent 19 and each of the terminals 9, 11, 13, 15, 17.
  • incoming calls to any of these telephones should be redirected to the same number. This number may, however, vary. For example, when the user is in the office, incoming calls should be redirected to the of- fice telephone 17. When the user is at home, incoming calls should be redirected to the home telephone 11. When the user is not in any of these places, incoming calls should be redirected to the mobile telephone 13, or, for example, to an answering service, in the way common in the art.
  • Figure 2 is a flow chart of the actions performed to redirect calls according to one embodiment of the invention.
  • Step S 1 The user initiates the forwarding of calls to one particular number. This may be done automatically, for example all calls may be forwarded to the mobile telephone when it is switched on. If the hook is lifted off one of the terminals, this may signal to the call forwarding agent that the calls should be forwarded to this terminal. Call forwarding may also be initiated manually, for example by dialling a particular code, or using speech recognition, or in any other way known in the art for communicating with the telecommunication network.
  • Step S2 The user is allowed to select a group of terminals from which calls should be forwarded. This is an optional step, which may also be carried out at other times.
  • Step S3 The user is allowed to verify that call forwarding is to be effected from the specified group of telephones. This step is optional Step S4: Forwarding of calls from all terminals in the specified group of terminals is effected by the call forwarding agent.
  • the call When a call is made to one of the terminals in the specified group of telephones, the call will be automatically redirected to the selected terminal, usually the terminal from which the call forwarding was initiated.
  • WO/34985 describes a solution in which the user carries a device transmitting an identification signal which can be detected by telephones to deter- mine at what terminal the subscriber may be reached at any given time.
  • the call forwarding procedure can normally only be carried out from the terminal from which calls are to be for- warded. According to the invention it must be possible to initiate call forwarding from a several telephone numbers to one telephone number, from the latter number, i.e. the terminal at the number to which calls are to be forwarded.
  • One solution to this problem would be to specify certain numbers from which call forwarding for a particular terminal may be initiated, possibly with restrictions, so that calls may only be redirected to the terminal from which call forwarding is initiated.
  • the mobile terminal or, actually the SIM card inserted in the mobile terminal, may be registered as authorized to forward calls from the office telephone and the private PSTN tele- phone to itself.
  • a priority order may be established, so that call forwarding initiated from one of the terminals would override call forwarding initiated from another terminal. For example the last change made will always be valid, or the change made from a specific number will always override all other changes regarding that terminal.
  • An identification code may also be associated with each terminal, so that call forwarding from that terminal may be initiated from any other terminal provided the correct code was entered.
  • An identification code may also be associated with each terminal, so that call forwarding from that terminal may be initiated from any other terminal provided the correct code was entered.

Abstract

La présente invention concerne, dans un réseau de télécommunications où un utilisateur est joignable à plusieurs terminaux, un procédé permettant de commuter sur le terminal auprès duquel se trouve actuellement l'abonné considéré les appels pour cet abonné. Ce procédé consiste, d'abord à détecter celui des terminaux par lequel l'abonné a choisi de se faire appeler actuellement, puis à instaurer automatiquement une fonction de transfert d'appels des autres terminaux par lesquels l'abonné peut se faire appeler vers le terminal par lequel l'abonné a choisi de se faire appeler actuellement. Le procédé consiste ensuite à renvoyer automatiquement sur le terminal par lequel l'abonné a choisi de se faire appeler actuellement tous les appels entrants arrivant sur l'un quelconque des terminaux sélectionnés, et enfin de restaurer ou d'annuler la fonction de transfert d'appel lorsque l'abonné choisit un autre terminal. L'invention concerne également un agent de transfert d'appel conçu pour enregistrer automatiquement pour au moins un premier terminal, au moins un autre terminal à partir duquel tous les appels entrants doivent être renvoyés vers le premier terminal.
