Address redirection for nodes with multiple internet protocol addresses in a wireless network

摘要

Systems and methodologies are described that facilitate obtaining an Internet Protocol (IP) address of a node with multiple IP addresses using address redirection in a wireless communication environment. A wireless communication component can retrieve a previously registered IP address corresponding to the node from an Authentication, Accounting, and Authorization/Home Subscriber Server (AAA/HSS). Further, a reverse query of a Domain Name Server (DNS) and a forward query of the DNS can be performed. The reverse query can be constructed based upon the previously registered IP address of the node and can resolve a name (e.g., string, . . . ). Further, the forward query can be formed based upon the name and can return a differing IP address of the node.

1. A method, comprising:
retrieving a previously registered Internet Protocol (IP) address corresponding to a node from an Authentication, Accounting, and Authorization/Home Subscriber Server (AAA/HSS), the previously registered IP address associated with a first function, wherein more than two IP addresses are associated with the node; retrieving a user plane IP address of a Packet Data Network Gateway (PDN GW) from the AAA/HSS at a Mobility Management Entity (MME); selecting a prefix from a set of prefixes, wherein each prefix in the set of prefixes corresponds to a different function supported by the node, and wherein the selected prefix corresponds to a second function supported by the node; performing a reverse query of a Domain Name Server (DNS) formed as a function of the user plane IP address by the MME, the reverse query constructed based upon the previously registered IP address for the node; receiving a name from the DNS in response to the reverse query; performing a forward query of the DNS, the forward query constructed based upon the selected prefix and the name; receiving a disparate IP address for the node in response to the forward query of the DNS, the disparate IP address associated with the second function; receiving a control plane IP address for the PDN GW in response to the forward query of the DNS at the MME; initializing a General Packet Radio Service (GPRS) Tunneling Protocol (GTP) bearer using the control plane IP address; and switching between different types of access, based on at least one of the first function and the second function, using the previously registered IP address and the disparate IP address.
