Definitions

  • the invention relates to a method for activating a call diversion of at least one incoming call for a first telecommunications terminal at a switching center to a second telecommunications terminal.
  • the invention relates to a telecommunication system which is set up to divert calls from at least one incoming call for a first telecommunication terminal to a switching center to a second telecommunication terminal.
  • Call forwarding is a diversion service in a telecommunications network, e.g. the PSTN network or the GSM network, which, under specified conditions (e.g. busy, no call acceptance, switchover by the subscriber) of the selected destination connection, redirects incoming calls to a specific alternative connection.
  • This operating mode is usually also referred to as call forwarding.
  • the ISDN network or digital mobile radio networks have call forwarding as a feature. Call forwarding can take place in your own network, but also to other networks; So from ISDN connections to analog telephone connections or also to radio telephone connections in cellular networks. Call forwarding can take place under various conditions: For example, call forwarding can take place directly, with a time delay, when the line is busy or when there is no answer. In the first case, every call is immediately forwarded to the destination connection. In the case of delayed forwarding, the switchover takes place if the call has not been answered after a certain period of time or after a certain number of ringing signals. When transferring calls, the caller pays the usual Usually the connection charges up to the called party, the charges for the second, forwarding connection section are mostly borne by the called party. Only one forwarding is possible per connection.
  • call forwarding is usually activated by pressing a key on the telecommunication terminal in accordance with the keyboard protocol and entering a code and the call number of the telecommunication terminal to which incoming calls are to be forwarded.
  • automatic call forwarding can be activated, for example, using the key combination: "** 21 * 0511900 + D1- # Send key”.
  • call forwarding can also be activated by entering a key combination and the number of the telecommunication terminal to which the call is to be diverted.
  • the key or key combination that is used to activate or deactivate call forwarding is usually referred to as hook flash. After activating the hook flash, a connection is established with an exchange, and an access code for the call forwarding service must also be entered. The number of the connection to which incoming calls are to be diverted by the exchange must then be announced.
  • a disadvantage of the known solutions is above all that the subscriber to whom the connection is assigned to which the call diversion takes place cannot be informed of this during the activation process of the call diversion. That is, the subscriber to whom the call is to be diverted has no option to give his consent to the call diversion. Furthermore, the known methods involve the risk that an incorrect number - by mistake - is incorrect is entered for the connection to which the call is to be diverted. In addition, it is disadvantageous in the known solutions for initializing call forwarding that it is necessary to enter a large number of numbers - access code, call number of the second telecommunication terminal - within a short time, the time available for initiating call forwarding being limited ,
  • This object is achieved according to the invention with a method of the type mentioned at the outset in that a call is set up between the first and the second telecommunication terminal and then a command to forward the call to the second telecommunication terminal and at least one call forwarding condition are entered via the first telecommunication terminal and transmitted to the switching center , which activates the call forwarding from the first to the second telecommunication terminal after receiving the command and the call forwarding condition.
  • the solution according to the invention makes it possible to set up a call connection between the telecommunication terminals involved as part of the activation of call forwarding. As a result, the subscriber who wishes to forward the call to the call partner's connection can inform him of the call forwarding as soon as it is activated. Furthermore, the solution according to the invention can minimize the risk of entering an incorrect call number for the connection to which call diversion is to take place.
  • At least one telecommunication terminal is an ISDN terminal.
  • Another variant of the invention provides that at least one telecommunications terminal is an analog telecommunications terminal.
  • a particularly favorable variant of the invention provides that the call numbers of the first and the second telecommunication terminal and the call forwarding condition are stored in a storage unit by the exchange after receipt of the call forwarding command.
  • the switching center can use the call forwarding conditions to check whether an incoming call for the first telecommunication terminal is to be diverted to the second telecommunication terminal.
  • the call forwarding condition can advantageously be entered in the form of a numeric or alphanumeric code via a numeric and / or alphanumeric input unit of the first telecommunication terminal.
  • a telecommunication system of the type mentioned at the outset is particularly suitable for carrying out the method according to the invention, which is set up to set up a call to the second telecommunication terminal after the call has been set up between the first and the second telecommunication terminal for forwarding calls to the second telecommunication terminal and at least one call forwarding condition to be transmitted to the switching center, the switching center being set up to activate the call diversion from the first to the second telecommunication terminal after receiving the command and the call forwarding condition.
  • At least one telecommunications terminal is advantageously an ISDN terminal.
  • At least one telecommunications terminal is an analog telecommunications terminal.
  • the first telecommunication terminal t has an input unit for inputting the call forwarding command and the call forwarding condition.
  • the exchange is set up to store the call numbers of the first and the second telecommunication terminal in a storage unit after receipt of the call forwarding command.
  • the switching center can be set up to check whether an incoming call for the first telecommunication terminal is to be diverted to the second telecommunication terminal.
  • the first telecommunication terminal has a numerical or alphanumeric input unit and is set up to accept the call forwarding condition in the form of a numeric or alphanumeric code via the input unit.
  • FIG. 1 shows a telecommunication system according to the invention
  • Fig. 2 is a flowchart of the method according to the invention
  • Fig. 3 is a flowchart of a call forwarding of an incoming call.
  • a telecommunication system SYS has at least two telecommunication terminals TE1, TE2, which are connected to one another via a telecommunication network NET and a switching center VER.
  • the telecommunications network NET can be, for example, an ISDN network, a PSTN or GSM network, or a combination of these networks.
  • the telecommunications terminals TE1, TE2 can be, for example, analog or ISDN terminals, but also mobile radio devices.
  • a call is set up RUF from the first telecommunications terminal to the second telecommunications terminal TE2.
  • the call number RU2 of the second telecommunication terminal is entered via the first telecommunication terminal TE1, for example via a keyboard, and transmitted to the switching center VER.
  • the switching center VER tries to establish a connection between the two telecommunication terminals TE1, TE2.
  • the switching center VER therefore transmits a free or busy signal SIG to the first telecommunication terminal TE1 depending on the operating state of the called telecommunication terminal TE2 - or busy signal SIG by the first telecommunication terminal TE1 can be sent via this telecommunication terminal TEl BEF for call forwarding and a call forwarding condition BED, for example: "Call forwarding if the line is busy";"automatic call forwarding";"Call forwarding if there is no answer", are entered and transmitted to the switching center VER.
  • a call forwarding condition BED for example: "Call forwarding if the line is busy";"automatic call forwarding";"Call forwarding if there is no answer
  • the switching center can have a control STR which is set up to activate the call forwarding of incoming calls for the first telecommunication terminal TE1 to the second telecommunication terminal TE2 and the call forwarding condition BED and call numbers RUL after receiving the command BEF for call forwarding and the call forwarding condition BED , RU2 of the two telecommunication terminals TE1, TE2 in a storage unit SPR.
  • a call forwarding can then be carried out by the control STR on the basis of this data stored in the storage unit SPR.
  • combinations of call forwarding conditions BED are also possible, such as: "Call forwarding if there is no answer" and "Call forwarding if the line is busy".
  • the call forwarding conditions BED can be entered as code COD (FIG. 2) in numerical or alphanumeric form, as is known, for example, from ISDN telephones.
  • the call forwarding conditions can also correspond to the call forwarding conditions known from ISDN or GSM services.
  • the call number RU1 of the first telecommunication terminal TE1 can be stored in the storage unit SPR of the exchange VER together with the call number RU2 of the telecommunication terminal TE2 to which the call is to be diverted for the purpose of call diversion.
  • the control STR can use the number RU1, RU2 stored in the memory SPR to check whether a call RUFA arriving at the switching center VER (Fig. 3), which is intended for the first telecommunications terminal TEl, is to be redirected.
  • the call RUFA can be diverted using the stored call number RU2 of the telecommunications terminal to which the call is to be diverted.
  • the call number RU2 of the second telecommunication terminal TE2 is entered via the first telecommunication terminal and transmitted to the switching center VER for the purpose of establishing a call RUF.
