Abstract
Abstract A method and system for transmitting specific information, such as access specific roaming information and/or application specific information, between a home network and a visiting access network is provided. The home network and visiting network are capable of communicating access independent information in a protocol, such as a AAA protocol. The access and/or application specific information is formatted in the AAA protocol. The access and/or application specific information is then transmitted over a public IP network between the home network and the visiting network. A system is provided for transmitting access and/or application information between a visiting network and a home network over a public IP network. A control access server in the visiting access network formats the access information using a secure AAA protocol to form formatted access information. An application server formats application specific information. A AAA-F server associated with the visiting network transmits the formatted access and/or application information over the public IP network to the home network.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
70 words
A wireless communications system comprising: a visited network including a Visitors Location Register (VLR) that generates a Mobile Application Part (MAP) message, and encapsulates said MAP message according to an access independent protocol; and an access independent authentication server (AAA-F) communicatively connected to said VLR for receiving said encapsulated MAP message from said VLR, and routing said encapsulated MAP message over a public IP network to a subscriber's home network.
Claim 2
Dependent Claim
70 words
A wireless communications system comprising: a visited network including a Visitors Location Register (VLR) that generates a Mobile Application Part (MAP) message, and encapsulates said MAP message according to an access independent protocol; and an access independent authentication server (AAA-F) communicatively connected to said VLR for receiving said encapsulated MAP message from said VLR, and routing said encapsulated MAP message over a public IP network to a subscriber's home network.
Claim 3
Dependent Claim
18 words
The communications system of claim 1 wherein said AAA-F routes said encapsulated MAP message via a broker (AAA-B).
Claim 4
Dependent Claim
29 words
The communications system of claim 1 wherein said subscriber's home network includes a Home Location Register (HLR), and wherein said AAA-F routes said encapsulated MAP message to said HLR.
Claim 5
Dependent Claim
25 words
The communications system of claim 3 wherein said HLR is operable to transmit and receive said encapsulated MAP messages according to said access independent protocol.
Claim 6
Dependent Claim
26 words
The communications system of claim 4 wherein said HLR is further operable to encipher and decipher said encapsulated MAP messages according to said access independent protocol.
Claim 7
Dependent Claim
42 words
The communications system of claim 1 wherein said visited network further includes an application server (AS) for generating and encapsulating an authentication message for transmission to an Application Home Server (AHS) in said subscriber's home network according to said access independent protocol.
Claim 8
Dependent Claim
31 words
The communications system of claim 6 wherein said AAA-F receives said encapsulated authentication message from said AS, and routes said encapsulated authentication message over said public IP network to said AHS.
Claim 9
Dependent Claim
21 words
The communications system of claim 7 wherein said AAA-F routes said encapsulated authentication message to said AHS via a broker (AAA-B).
Claim 10
Dependent Claim
25 words
The communications system of claim 8 wherein said AHS is operable to transmit and receive said encapsulated authentication message according to said access independent protocol.
Claim 11
Dependent Claim
26 words
The communications system of claim 9 wherein said AHS is further operable to encipher and decipher said encapsulated authentication message according to said access independent protocol.
Claim 12
Dependent Claim
18 words
The communication system of claim 1 wherein said visited network and said subscribe's home network are CDMA networks.
Claim 13
Dependent Claim
15 words
The communication system of claim 1 wherein said MAP message is an ANSI-41 registration message.
Claim 14
Dependent Claim
15 words
The communication system of claim 1 wherein said MAP message is an ANSI-41 authentication message.
Claim 15
Dependent Claim
15 words
The communications system of claim 1 wherein said access independent protocol includes an AAA protocol.
Claim 16
Dependent Claim
14 words
The communications system of claim 14 wherein said AAA protocol is a DIAMETER protocol.
Claim 17
Independent Claim
78 words
A method of communicating messages in a wireless communications system, the method comprising: generating a MAP message at a VLR in a visited network; encapsulating said MAP message at said VLR according to an access independent protocol; forwarding said encapsulated MAP message to an AAA-F server communicatively connected to said VLR; communicating over a public IP network, said encapsulated MAP message from said AAA-F server to a subscriber's home network; and receiving a response to said formatted message.
Claim 18
Independent Claim
78 words
A method of communicating messages in a wireless communications system, the method comprising: generating a MAP message at a VLR in a visited network; encapsulating said MAP message at said VLR according to an access independent protocol; forwarding said encapsulated MAP message to an AAA-F server communicatively connected to said VLR; communicating over a public IP network, said encapsulated MAP message from said AAA-F server to a subscriber's home network; and receiving a response to said formatted message.
Claim 19
Dependent Claim
26 words
The method of claim 16 wherein encapsulating said MAP message according to an access independent protocol comprises encrypting said MAP message according to AAA protocol encryption.
Claim 20
Dependent Claim
24 words
The method of claim 17 wherein encapsulating said MAP message according to an access independent protocol further comprises including a Network Access Identifier (NAI).
Claim 21
Dependent Claim
33 words
The method of claim 18 wherein communicating said encapsulated MAP message from said AAA-F server includes routing said encapsulated MAP message to a HLR in said subscriber's home network based on said NAI.
Claim 22
