[0016] The nature, objects and advantages of the present invention will become more apparent to those skilled in the art from consideration of the following detailed description when taken in conjunction with the accompanying drawings.

[0017] Hardware Components and Interconnects

[0018] Introduction

[0019] One aspect of the invention is a wireless communication system, which can be implemented in a number of different ways. Figure 1A Showing an example 100, Figure 1B Another example 150 is shown. In either case, the communication switching network includes a mobile IPv4 network configured to relay IPv4 type messages between mobile communication devices (“mobile stations”) and the Internet 102 . exist Figure 1A In the case where network 100 is shown comprising an IP-capable wireless telephone network, such as a CDMA network, mobile station 114 comprises an IP-capable wireless telephone. exist Figure 1B In the case where network 150 is shown comprising a non-IP w...

Abstract

In order to assist an exchange of data between one or mobile communications devices and the Internet in a mobile communications network, bidirectional tunneling of IPv6 messages inside IPv4 messages is performed between a home agent and one or more foreign agents. Optionally, where a mobile communications device is a wireless mobile unit, the mobile unit itself automatically engages in bidirectional tunneling of IPv6 messages inside IPv4 messages with the home agent whenever the wireless mobile unit detects loss of wireless coverage in the mobile communications network and presence of coverage in a type of wireless network lacking foreign agent functionality.

Description

technical field [0001] The present invention relates generally to the sending, relaying and receiving of messages in wireless telephone networks, and more particularly to the use of new formats of Internet Protocol (IP ) message technology. Background technique [0002] According to a well-known standard, each entity coupled to the Internet is identified by a unique code called an "IP address". For example, a computer receives an IP address when it activates a dial-up modem to connect to the Internet. The same is true for Internet routers, servers, and other traditional components of the Internet. Certain entities have all-time, permanent IP addresses known as "static" IP addresses, while other entities receive a new "dynamic" IP address each time they connect to the Internet. [0003] Recently, the dominant standard for notifying IP addresses is "IPv4" promulgated by the Internet Engineering Task Force (IETF). IPv4 specifies an IP address format with a length of 32 bits...
