Automated IPv4-IPv6 Selection for Voice Network Elements

Abstract

A computing device, such as a mapping application server, may track data associated with a plurality of user devices, such as an Internet Protocol version. A system, such as an IMS system, may use may use the data associated with the plurality of user devices to process messages. When messages between devices are received, the computing device may provide information regarding at least one protocol associated with a communication. The computing device may respond to queries from various network elements. The responses may provide data that may be used to identify a protocol version, such as a Name Authority Pointer (NAPTR). Any necessary protocol interworking may be provided by the system.

1 . A method comprising:
 receiving, by a call session control function (CSCF) device, a call message;   building, based on a determination that an IP version interworking is necessary, an interworking call message; and   sending the interworking call message to a target user device.
