DISCOVERING AN ADDRESS OF A NAME SERVER

摘要

A mobile communications network includes a packet service node (2 6) capable of establishing a session with a mobile station. A network address (e.g., an Internet Protocol or IP address) of a domain name system (DNS) server (54) is communicated to the mobile station (16) using one of several type of messages. A first type of message includes an Internet Protocol Control Protocol (IPCP) message. A second type of massage includes a Mobile Internet Protocol Registration Reply Message. The packet service node (26) receives the network address of the DNS server (54) from an authentication server (34), such as a RADIUS (Remote Authentication Dial In User System Service) server or a Mobile IP Authentication, Authorization, and Accounting (AAA) server.
