Domain name system (DNS) IP address distribution in a telecommunications network using the protocol for carrying authentication for network access (PANA)
First Claim
1. A method for sending a Domain Name Server (DNS) IP address to a Mobile Node (MN) in a telecommunications network, the method comprising the steps of:
- i) selecting at least one DNS IP address for transmission to the MN; and
ii) sending from the packet data switching node to the MN a first Protocol for Carrying Authentication for Network Access (PANA) message comprising the at least one DNS IP address for the MN.

Abstract
A method, a packet data switching node such as for example a CDMA2000 Packet data Serving Node (PDSN), and a Mobile Node (MN) for assigning one or more DNS IP addresses to the MN in a telecommunications network. The switching node and the MN are first involved in a discovery phase, and then the MN sends a Protocol for Carrying Authentication for Network Access (PANA) Start-Answer message to the switching node with a request for a DNS IP address. The switching node receives the PANA Start-Answer message and recognizes the request for the DNS IP address. It authenticates the MN, possibly in combination with an Authentication, Authorization, and Accounting (AAA) server, and if the authentication is successful, assigns a primary DNS IP address and a secondary DNS IP address for the MN, and responds back to the MN with a PANA Bind-Request message comprising one or more assigned DNS IP addresses.

12. A packet data switching node for assigning at least one Domain Name Server (DNS) IP address to a Mobile Node (MN) in a telecommunications network, the packet data switching node comprising:
-
a memory storing at least one DNS IP address;
a Protocol for Carrying Authentication for Network Access (PANA) Authentication Agent (PAA) module;
wherein the PDSN selects the at least one DNS IP address for transmission to the MN, and the PANA module issues to the MN a first PANA message comprising the at least one DNS IP address for the MN. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A Mobile Node (MN) comprising:
-
a Protocol for Carrying Authentication for Network Access (PANA) Authentication Client (PAC) module;
a memory for storing at least one Domain Name Server (DNS) IP address;
wherein the PAC module receives a first PANA message comprising the at least one DNS IP address for the MN, extracts the at least one DNS IP address and stores the at least one DNS IP address in the memory. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
