Abstract

A method and apparatus for transmitting and receiving SS7 user adaptation messages (301) is provided herein. In accordance with the preferred embodiment of the present invention, an SS7 application proxy function (105) is provided that receives particular SS7 User Adaptation Messages (301) within an IP packet (300), determines the type of application requested, and forwards these messages to an appropriate application (106). Because standard SS7 messages (301) are transmitted via an IP transport, the transport advantages if IP are combined with the existing applications/services provided by SS7.

Claims

1. A method for receiving and executing an application query message via an internet protocol transport, the method comprising the steps of:

receiving an Internet Protocol (IP) packet;

extracting an SS7 user adaptation (SUA) message from the IP packet;

determining an appropriate user application from the SUA message;

determining an appropriate address for execution of the user application;

re-encapsulating the SUA message within a second IP packet; and

forwarding the SUA message to the appropriate address for execution of the user application.

2. The method of claim 1 wherein the step of determining the appropriate user application from the SUA message comprises the step of determining the appropriate user application, wherein the user application is chosen from the group consisting of user authentication, caller identification, call forwarding, and call roaming.

3. The method of claim 1 wherein the step of determining the appropriate address for execution of the user application comprises the step of determining an appropriate IP address for execution of the user application.

4. A method for receiving and executing an application query message via an Internet Protocol (IP) transport, the method comprising the steps of:

receiving an IP packet;

extracting an SS7 User Adaptation (SUA) message from the IP packet;

determining an appropriate user application from the SUA message, wherein the step of determining the appropriate user application from the SUA message comprises the step of determining the appropriate user application, wherein the user application is chosen from the group consisting of user authentication, caller identification, call forwarding, and call roaming;

determining an appropriate IP address for execution of the user application;

re-encapsulating the SUA message within a second IP packet; and

forwarding the SUA message to the appropriate address for execution of the user application.

5. An apparatus for receiving and executing an application query message via an internet protocol transport, the apparatus comprising:

logic circuitry having a first IP packet as an input and a second IP packet as an output, wherein the first IP packet comprises an SS7 User Adaptation (SUA) message and a first IP address, and the second IP packet comprises the SS7 User Adaptation message and a second IP address; and

an SS7 application database coupled to the logic circuitry, the SS7 application database providing the logic circuitry with the second IP address.

6. The apparatus of claim 5 wherein the second IP address comprises an IP address of a User Adaptation Protocol (SAP) utilized to execute an application defined by the (SUA).
