Definitions

  • the invention relates to a method according to the preamble of claim 1 for redirecting a call.
  • the invention also relates to a system suitable for redirecting a call.
  • Patent publication FI 101,663 describes a method suited for redirecting a call connected to a terminal to some other target number even after answering the call.
  • the terminal user person or machine
  • the terminal user that has answered the call hangs up shortly, goes back off hook now by calling a dialing-receiving device, dials the target number to the device thus indicating the desired target number of desired call redirection and hangs up after the entry/entries of the data required for the desired call redirection.
  • This method is hampered by the following shortcomings.
  • the party redirecting the call must carry out a complicated sequence of actions and concentrate on the dialed number. Hence, redirection is so complicated that the operation is inconvenient to perform from any telephone set.
  • the method requires answering to an incoming call, thus forcing the caller to pay also for the time consumed in the call redirection.
  • the method described in cited publication does not permit the redirection of a call established by the calling party, that is an outgoing call, by virtue of the disclosed method.
  • another approach is required and the user must learn at least two different procedures: one for linking calls established in the role of the calling party and another for redirecting an answered incoming call.
  • the goal of the invention is achieved by virtue of using in the method a communications connection not linked with the call to be redirected nor to its control connection (signaling path), said communications connection serving to transmit the call control information over a network (such as the Internet) not serving the actual call connection to a signaling server (typically a WEB server) that in turn sends the information to a centralized control point (typically an SCP) of the network.
  • a signaling server typically a WEB server
  • SCP centralized control point
  • the invention is implemented by way of designing the redirection procedure and the technique serving the same such that the call redirection can be performed in a simple manner by means of a few functions.
  • This goal is attained by virtue of using a signaling protocol or protocols, which is/are compatible with the terminal(s) used (e.g., WAP, Wireless Application Protocol, or the like) but is not associated with the actual telephone connection, for transmitting the redirection information of the ongoing call between the terminal and the call-managing unit of the network to a control device (typically a WEB server) utilizing said information that in turn sends the information to a device managing the ongoing call (typically an SCP) in a format compatible with the latter device.
  • a signaling information for call control is transmitted over a communications path separate from the actual telephone communication path.
  • the method according to the invention concerns, for the purpose of managing a call, the use of a communications facility that operates separate from the signaling system of a conventional public switched telephone network and transmits information over a communications path separate from the telephone connection.
  • the system according to the invention comprises a server connected over a communications path separate from a telephone connection to at least one terminal of the system and a data base, the server being capable of communicating with said terminal using a signaling protocol different from that of the telephone connection, the server further being capable of converting the information received from said terminal into a format compatible with said data base and of converting the information received from said data base into a format compatible with said terminal thus performing a protocol conversion.
  • the method according to the invention is characterized by the specifications disclosed in the characterizing part of claim 1.
  • the invention offers significant benefits.
  • the invention it is possible to perform redirection of calls or pagings also in a situation wherein the call passes over the interfaces of two different networks (e.g., an Internet voice connection in which the call is initiated from the Internet and is passed to a conventional telephone network and vice versa). It is also possible to perform the call redirection from mobile telephones or the like terminals/networks in which a normal telephone connection is released when the user goes on-hook.
  • the system according to the invention permits the user to avail of a menu- based user interface in which call redirection is effortless.
  • FIG. 1 is a block diagram illustrating a first embodiment of the method according to the invention.
  • FIG. 2 is a block diagram illustrating a second embodiment of the method according to the invention.
  • FIG. 1 a call redirection procedure after the user has answered the incoming call.
  • the call is connected from a terminating switching office 1 of a tele- phone network to a terminal 2 in a conventional manner.
  • the terminating switching office 1 is an SSP equipped with intelligent network facilities.
  • the user of the terminal 2 answers the incoming call and, at recognizing the need for call redirection, selects from a menu 3 of his terminal 2 item "redirect call" and then item "target number for redirection".
  • the menu 3 may contain a plurality of stored target numbers or the menu 3 may be updatable either from the terminal 2 or from the network.
  • Target number list update from a terminal occurs in a manner compatible with the terminal type using, e.g., the routines of the WAP or via text messages or the like.
  • the terminal 2 uses such a compatible protocol, the terminal 2 sends the information 4 selected from the menu 3 to a server 5, typically a WEB server, operating in a network separate from that of the ongoing call and capable of interpreting the protocol used.
  • the server 5 transmits the information to a network device 6 responsible for handling the request for call redirection converted into a format compatible with the network device 6 that typically is the data base of an intelligent network control point (SCP).
  • SCP intelligent network control point
  • the control point 6 sends a control message 7 in a proper format, that is, now compatible with the signaling protocol used in the telephone traffic management to the switching office 1 , which as a result thereof performs connection 8 of the call to the desired target 9.
  • the control message 7 is sent immediately after the user of the terminal 2 releases the original incoming call by depressing the pushbutton that sends the "B on-hook" signal.
  • depressing the pushbutton "B on-hook" controls the terminating switching office 1 to send a message about the call release 25 to the network control point device 6.
  • the call control procedure comprises the following steps:
  • the call is first connected in a normal manner from the terminating switching office 1 (typically an SSP equipped with intelligent network facilities) of a telephone network to a terminal 2.
  • the user of the terminal 2 decides to redirect the incoming call without answering the same due to, e.g., seeing from the displayed caller number that he has no need to answer the call on the spot.
  • the following procedure is carried out.
  • the user selects from the menu 3 of his terminal 2 item "redirect call” and then item "target number for redirection".
  • the menu 3 may contain a plurality of stored target numbers or the menu may be updatable either from a terminal or from the network (the former taking place in a manner compatible with the terminal type using, e.g., the protocol routines of the WAP or via text messages or the like).
  • the terminal 2 uses such a compatible protocol to send the information 4 selected from the menu 3 to a server 5, typically a WEB server, which can interpret the proto- col and operates in a network separate from that of the ongoing call.
  • the server 5 transmits the information to the network device 6, which typically the data base of an intelligent network control point (SCP) and is responsible for handling the request for call redirection, now converted into a format compatible with said network device.
  • SCP intelligent network control point
  • the server 5 is connected over a communications path to at least one database 6 and, at any time the terminal user sends control information from his terminal's menu, the telecommunications connection between the terminal and the server 5 is established using the selected signaling protocol.
  • the server 5 is capable of communicating with the terminal 2 using a signaling protocol which is different from that used for traffic management in the telecommunication network and also is capable of converting the information received from the terminal 2 into a format compatible with the data base 6 and, vice versa, is also capable of converting the information received from data base 6 into a format compatible with the terminal 2.
  • control point 6 When the user of the terminal 2 depresses the pushbutton "B on-hook", information 25 on the event is sent over the normal signaling path of the telecommunication network from the terminating switching office 1 to the network control point device 6.
  • the control point 6 On the basis of the received call release command and call redirection information earlier received via the server 5, the control point 6 generates and sends a control message 7 in a proper format, that is, now compatible with the signaling protocol used for telecommunication network traffic management, to the switching office 1, which as a result thereof performs the connection 8 of the call to the desired target number 9.
  • the call billing is based on the start instant of a call, as is the case in conventional telephone networks, the call charging to the caller is started not earlier than at the instant the call is answered at the new target number 9.
  • FIG.2 A method suited for linking two outgoing calls established separately is illustrated in FIG.2.
  • a first call is established in a conventional manner between a terminal 11 and a terminating switching office 12 of a telecommunication network.
  • the terminating switching office 12 is an SSP equipped with intelligent network facilities.
  • the call is routed to the dialed number having a B-subscriber terminal 20 connected thereto.
  • Target number list update from a terminal occurs in a manner compatible with the terminal 11 using, e.g., the protocol routines of the WAP or via text messages or the like.
  • the terminal 11 uses such a compatible protocol to send the information 14 selected from the menu 13 to a server 15 of the network, which can interpret the protocol and operates in a network separate from that of the ongoing call.
  • the server 15 is a WEB server that transmits the information to the network device 16 responsible for handling the request for call redirection.
  • the network device is typically the data base of an intelligent network control point (SCP).
  • the control point 16 sends a control message 17 in a proper format, that is, now compatible with the used signaling protocol to the switching office 12, which as a result thereof performs the connection 18 of the call to the second desired target number 19, thus establishing another call.
  • the network device 16 Upon receiving the information 21 "Call established” (actually meaning “Target numbers received”), "Call set-up” or the like control message, the network device 16 performs the following steps.
  • the information 22 indicating the that the call has been established is transmitted to a server 15 not associated with the actual telephone connection, whereupon the server 15 sends with help of the used signaling protocol the information further, e.g., to the menu 13 of the terminal 11, wherefrom the user of the terminal 11 can verify the call to be established.
  • This kind of information can be displayed graphically, e.g., as text "Connected” or via some other kind of visual "annunciation symbol".
  • the information may be conveyed by a signal tone or musical tune emitted by the terminal.
  • the network device 16 sends a control message or messages 23 to the terminating switching office 12, whereupon the switching office releases the connection between the switching office 12 and the terminal 11 wherefrom the linking of the two calls was performed and establishes a connection between the terminal 20 of the first called number and the terminal 19 of second called number.
  • the target number selection may be performed freely instead of using a menu for the selection.
  • the user may be provided with a facility of updating the information stored in the network facilities over, e.g., an Internet connection, whereby obviously normal data transfer authorization measures must be arranged.

Abstract

Cette invention concerne un procédé et un système de renvoi d'appels, par exemple dans le cadre du ré-acheminement de communications. Selon ce procédé, les communications sont établies, au moins partiellement, sur un réseau téléphonique public commuté (1, 6, 16, 12) au moyen du protocole de signalisation dudit réseau. Pendant la communication, l'information de signalisation (14) est émise et reçue au niveau du terminal (2, 11) via un trajet de communication distinct de celui utilisé pour la communication téléphonique réelle, au moyen d'un protocole de signalisation différent de celui utilisé pour la gestion des appels dans un réseau téléphonique public commuté. La signalisation, qui se distingue de celle utilisée pour la gestion des appels dans un réseau téléphonique public commuté, est convertie en une signalisation normale pour gestion des appels, puis transmise, via le réseau public commuté, pour la gestion de la communication en cours.
