Abstract

In a particular embodiment a system and method for processing a call in a Voice over internet protocol (VoIP) network are disclosed. The method includes receiving the call associated with a private identifier (PRID) at a server, classifying a call location based on the PRID and sending the call from the server to a Public Safety Answering Point (PSAP) with a call back number associated with the PRID. The system includes a first server interface for receiving a message containing a PRID associated with the call, a second server interface to access the data base for searching for the PRID in the data structure; a third server interface to receive an output from the database indicating whether a PRID has been found in the data structure; and a fourth server interface to send the call to a PSAP.

Claims

1-20. -20. (canceled)

21. A method for processing call data in a Voice over internet protocol (VoIP) network, the method comprising:

receiving at a server from a network access device, call data containing a private identifier (PRID) datum, the PRID datum indicating a user equipment device (UED) identifier and indicating a call location mobility for the UED, a public identifier (PUID) for the UED and a network access device identifier (NID) for the call data for classifying the call location mobility at the server based on a database entry indicating the call location mobility for the UED identifier indicated by the PRID;

processing the PRID, PUID and NID to find at least one of a matching PRID, PUID and NID; and

determining from the NID and PRID whether the UED is visiting a known location;

if the if the VoIP access port is not visiting a known visiting location, announcing to a public safety answering point (PSAP) that the location is not verified and inserting a location not verified disclaimer in the call data when the VoIP access port location is not at a known location.

22. The method of claim 21 instructions to send the call data with the call back number from the server to the public safety answering point (PSAP) based on the mobility for the user equipment device and the NID.

23. The method of claim 21, the computer program further comprising instructions if the UED is visiting a visiting location, comparing a VoIP access port internet protocol address for the visiting location with a public internet protocol address in the data structure for the PRID, to determine if the VoIP access port is visiting a known location.

24. The method of claim 21, the method further comprising:

requesting a location further from at least one of a set consisting of a caller, global positioning system (GPS), wireless fidelity (WIFI) proximity, cellular triangulation, WIFI proximity and a national database.

25. The method of claim 21, wherein the PRID is received in a session initiation protocol (SIP) message from a VoIP device sent to the server.

26. A server comprising:

a processor in data communication with data embedded in a tangible, non-transitory computer readable storage medium for storing data used by the processor; and

a computer program stored in the computer readable medium, the computer program comprising instructions that executed by the processor perform functions useful to receive call data containing private identifier (PRID) data indicating a user equipment device identifier and indicating a call location mobility for the user equipment device identifier, a public identifier (PUID) for the user equipment and a network access device identifier (NID) for the call data;

instructions to classify the call location mobility based on a database entry indicating the call location mobility for the user equipment device indicated by the PRID;

instructions to, if the PRID, PUID and NID do not produce one of a matching PRID, PUID and NID, then instructions to insert a “

location not verified”

disclaimer in the call when the VoIP gateway location is not known; and

instructions to insert call back number (CBN) data associated with the NID into the call data;

27. The server of claim 26, wherein the computer program further comprises instructions to send the call data with the call back number from the server to the public safety answering point (PSAP) based on the mobility for the user equipment device and the NID.

28. The server of claim 26, wherein the computer program further comprises instructions to receive session initiation protocol (SIP) message data containing the PRID from a voice over internet protocol (VoIP) device.

29. The server of claim 28, the computer program further comprising:

instructions to retrieve the VG ID associated with a PRID; and

instructions to further retrieve all other VoIP devices from the database that are associated with the same VG ID.

30. The system of claim 28 wherein the computer program further comprises:

instructions to compare a VOIP access port internet protocol address with an internet protocol address for the PRID to determine if the VoIP access port is at a known location; and

instructions to return a call back number for the VoIP access port when the VoIP access port is at a known location.

31. The system of claim 30, wherein the computer program further comprises:

instructions to request a location from at least one of a set consisting of a caller, global positioning system (GPS), wireless fidelity (WIFI), triangulation and a national database.

33. The medium of claim 31 wherein the data structure further comprises:

a public internet protocol address field for storing a public internet address for the user equipment.

32. A tangible non-transitory computer readable storage medium having stored thereon a data structure for storing identification information data for a voice over internet protocol (VoIP) user equipment device (UED), the data structure comprising:

a private identifier field for storing a private identifier (PRID) datum associated with the UED, the PRID datum indicating a UED identifier and indicating a call location mobility for the UED;

a public identifier (PUID) field for storing data indicating a PUID for the user equipment;

a network access device identifier (NID) field for string NID data indicating a network access device from which the call data originated; and

an internal flag field for storing an flag datum indicating a UED is a fixed location UED.

34. The medium of claim 32 wherein the data structure further comprises:

a VoIP gateway identifier (VGID) internet protocol (IP) address field for storing a VGID IP address associated with the user equipment.
