  • Fig. 1 is a block diagram of a network for implementing services in accordance with one embodiment of the present invention.
  • public switched telephone network (“PSTN") 100 is connected to an internet 102 by an internet service provider (“ISP") network 104.
  • ISP network 104 includes a remote access server 106 that preferably interfaces with one or more switches 108 of the PSTN 100.
  • ISP network 104 also includes one or more ISP routers 110 which interface with internet nodes 112.
  • a conventional telephone based caller 114 can place conventional voice calls through the PSTN 100.
  • PC users 116 can dial into the internet 102 via a modem 118, which can also handle conventional calls from a telephone 120.
  • an intelligent network service control point (“ISCP") 122 is connected to one or more switches 108 of the PSTN 100.
  • ISCP 122 preferably comprises a Bellcore ISCP ® platform architecture to create and execute network services, and includes, for example, the SPACE ® and MSAP ® applications.
  • the ISCP 122 processes customer records and/or service records in response to queries from PSTN switches 108 and instructs switches 108 on how to handle and route calls.
  • the service further includes an internet telephony gateway ("ITG") 124 connected via data links to the ISCP 122, one or more switches 108 of the PSTN 100 and one or more nodes 112 of the internet 102.
  • ITG 124 preferably provides a communication path for voice signals into the internet 102.
  • Fig. 2 shows a call flow diagram for the system of Fig. 1 in accordance with one embodiment of the present invention.
  • An internet telephony client or "user" as referred to in Fig. 2 refers to, for example, a subscriber with access to the system via PC 116, modem 118, and/or telephone 120.
  • that user establishes an internet communication by calling into the internet service provider 110 (step 202).
  • the system registers that connection with the ITG 124 (step 204).
  • the registration may be performed, for example, by an application running on the user's PC 116 or at an ISP server.
  • the application sends the user's address and any other appropriate information to the ITG 124, or other network element that may perform the registration.
  • the switch 108 determines at that time that the user's line is busy because the user is communicating with the ISP network 124.
  • the switch queries the ISCP 122 for an instruction on how to process the call (step 208).
  • ISCP 122 executes a call processing record to provide the instruction (step 210).
  • FIG. 3 An example of such a call processing record is shown in Fig. 3.
  • ISCP 122 executes a send-to-resource with play application node (step 302).
  • This node sends a request to the ITG 124 for a routing number (step 212, Fig. 2).
  • the request includes the user's telephone number, which the ITG 124 uses to determine if the user is currently registered, i.e., on line with the internet.
  • the ISCP 122 determines the result of the send-to-resource application query (step 304) depending on the information returned by the ITG 124 (step 214, Fig. 2).
  • the query is considered a failure (step 306) if the user is not registered or if the ITG 124 has no available resources to handle the query.
  • the result is successful if the ITG 124 returns its routing number to the ISCP 122 (step 308).
  • the ISCP 122 transmits the instructions based on the result from the ITG 124 to the switch 108 (step 216).
  • the remaining call processing shown in Fig. 2 assumes that the user is registered with the ITG 124.
  • the switch 108 connects the caller 114 to the ITG 124 (step 218).
  • the ITG 124 can then send a signal to the user via the internet connection indicating that a call is waiting for the user (step 220).
  • the ITG 124 can send a signal to ring the user's telephone 120 or send data to display a message on the user's PC 116.
  • the user can then answer the call if desired through internet telephony client software running on the user's PC.
  • the switch 108 of PSTN 100 may handle the call in any conventional manner of telephone service. For example, the switch may simply send a busy tone to the caller 114, or it may direct the call 114 into the user's voice mail. Or, the switch 108 may send a call waiting indication to the user in accordance with know techniques.
  • the internet based telephone call established by the ITG 124 through the internet may use any internet protocol necessary to achieve the connection, including, for example, the H.323 protocol.
  • Fig. 4 shows an alternative embodiment of the invention where the ISCP 122 acts as the registration service for internet communications. This differs from the above embodiment where the internet telephony gateway 124 performed the registration.
  • the user establishes an internet based communication via the ISP network 104 (step 400).
  • the user registers with the ISCP 122 (step 402).
  • switches may be configured such that each time they establish a connection to a ISP network 104, they send an appropriate "registration" trigger and the user's telephone number to the ISCP 122.
  • the ISCP 122 will recognize the registration trigger and store the user's address with information indicating the user's existing access into the internet (step 404).
  • ISCP 122 executes a call processing record (step 410), as shown for example in Fig. 5.
  • the ISCP determines whether the user is registered (step 502). If not, the ISCP may send a conventional call processing instruction to the switch (step 504). Again, these instructions may include send a busy signal or connect the caller to the user's voice mail. If, however, the user is registered, the ISCP executes the same send- to-resource with play application (step 506) and send-to-resource result (step 508) nodes.
  • ISCP 122 instructs the switch to route the call to the ITG 124, giving the switch 108 the ITG routing number (step 510).
  • steps 412, 414, and 416 are similar to steps 212, 214, and 216 in Fig. 2.
  • the ISCP 122 instructs the switch on how to process the call (step 416). Assuming a successful result from the ITG 124, ISCP 122 instructs the switch to route the call to the routing number of the ITG 124 to establish a connection (step 418). The ITG 124 then informs the user of the existing telephone call as described above (step 420). Again, if the result comes back a failure, the ISCP may instruct the switch to handle the call in a more conventional manner, either by sending, for example, a busy signal, or forwarding the call to a voice mail.

Abstract

La présente invention concerne des procédés et un appareil fournissant un service téléphonique qui n'est jamais occupé à des utilisateurs d'Internet. Les utilisateurs d'Internet déclarent leur communication, par exemple, à une passerelle téléphonique d'Internet, à un point de commande de service de réseau intelligent (ISCP) ou à tout autre système de répertoire de réseau. Les appels téléphoniques adressés à l'utilisateur, lorsque ce dernier est en communication avec Internet, sont traités en conséquence. Le ISCP donne une instruction au commutateur de façon à acheminer un appel pour l'utilisateur vers la passerelle téléphonique si l'utilisateur y est enregistré. La passerelle téléphonique établit un appel téléphonique basé sur Internet vers l'utilisateur de façon à l'informer de l'appel téléphonique.
