Patent Images
1. A system for providing call back subscriber features within a communications network, said system comprising:
- a first local network in a first country for ordering a call back request;
a second local network in a second country for initiating a call setup to effectuate said call back request;
an Intelligent Peripheral (IP) within said first local network for receiving said call back request and formatting said call back request into a packet;
a computer communications link connecting said first local network to said second local network, for transporting said packet containing said call back request therebetween;
an interface module within said second local network for receiving said call back request packet over said computer communications link from said IP; and
a Common Channel Signaling System No. 7 (SS7) telecommunications network connecting said first local network to said second local network to establish a communications link effectuating said call back request from said second local network to said first local network.

Abstract
A telecommunications system receives a call back request though a separately maintained computer network, such as an X.25 based computer network, and initiates the actual call back toward the requesting subscriber using its own Signaling System No. 7 (SS7) telecommunications network. If the call back request fails, an X.25 packet containing an error code is transmitted back to the originating subscriber over the separately maintained computer network. An X.25<=>TCAP converter is used as an interface card to allow X.25 packets to communicate freely with TCAP based telecommunications network.

6. A system for providing a communications link between a first subscriber within a first country and a second subscriber within a second country, said system comprising:
-
a first telecommunications network servicing said first subscriber, wherein said first telecommunications network comprises a local switch connected to said first subscriber; a second telecommunications network servicing said second subscriber, wherein said second telecommunications network comprises; a Service Switching Point (SSP) connected to said second subscriber for providing telecommunications switching functions; and a Service Control Point (SCP) connected to said SSP for effectuating call back services; a Common Channel Signaling System No. 7 (SS7) telecommunications link between said first telecommunications network and said second telecommunications network for communicating voice data; a computer communications network connecting said first country to said second country for communicating packet data; a first interface device within said first country for receiving a call back request from said first subscriber and transmitting said call back request over said computer communications network; and a second interface device within said second country for receiving said transmitted call back request over said computer communications network and sending the received call back request to said SCP. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of providing subscriber call back services for a first subscriber within a first country toward a second subscriber within a second country, wherein said first country and said second country are connected using a Common Channel Signaling System No. 7 (SS7) telecommunications network and a X.25 based computer network, said method comprising the steps of:
-
receiving a call back request from said first subscriber by an Intelligent Peripheral (IP) within said first country; formatting said call back request into an X.25 based packet by said IP; transmitting said X.25 based packet over said X.25 based computer network from said first country to said second country; receiving said transmitted X.25 based packet by a converter within said second country; converting said transmitted X.25 based packet into a Transaction Capabilities Application Part (TCAP) message; and effectuating a call back service toward said first subscriber by a Service Control Point within said second country with the information from said received TCAP message. - View Dependent Claims (13, 14, 15)

16. A system for providing subscriber call back services for a first subscriber within a first country toward a second subscriber within a second country, wherein said first country and said second country are connected using a Common Channel Signaling System No. 7 (SS7) telecommunication network and a X.25 protocol based computer network, said system comprising:
-
means for receiving a call back request from a first subscriber; means for formatting said call back request into an X.25 based packet; means for transmitting said X.25 based packet over said X.25 based computer network; means for receiving said transmitted X.25 based packet within said second country; means for converting said transmitted X.25 based packet into a Transaction Capabilities Application Part (TCAP) message; means for sending said TCAP message to a Service Control Point (SCP) located within said second country; and means for effectuating a call back service toward said first subscriber by said SCP with information from said received TCAP message. - View Dependent Claims (17, 18, 19)
