Method for Route Transmission Based on Single IPv6 Address Prefix, and Wireless Device
First Claim
1. A method for implementing route transmission of a wireless device based on a single IPv6 address prefix, comprising:
- when a wireless device succeeds in IPv6-based dialing and obtains a 64-bit-long IPv6 address prefix from a network side, the wireless device first setting apart a 126-bit IPv6 address prefix from the prefix, and then allocating the 126-bit IPv6 address prefix to a wireless Wide Area Network (WAN) interface, allocating the 64-bit-long IPv6 address prefix to a Local Area Network (LAN) interface, and notifying a user terminal which is connected to the LAN interface of the IPv6 prefix of the LAN interface, so that the user terminal connected to the LAN interface generates an IPv6 address of itself through a stateless address auto-configuration mechanism for communication.

Abstract
The present document provides a method and wireless device for implementing route transmission based on a single IPv6 address prefix. The method includes: when a wireless device succeeds in IPv6-based dialing and obtains one 64-bit-long IPv6 address prefix from a network side, the wireless device first setting apart a 126-bit IPv6 address prefix from the prefix, and then allocating the 126-bit IPv6 address prefix to a WAN interface, allocating the 64-bit-long IPv6 address prefix to a LAN interface, and notifying a user terminal connected to the LAN interface of the IPv6 prefix of the LAN interface, so that the user terminal connected to the LAN interface generates its own IPv6 address through a stateless address auto-configuration mechanism for communication. With the technical solutions of the present document, in an IPv4/IPv6 dual stack mode, IPv4 and IPv6 protocol stacks operate normally, and the radio resource consumption is reduced.

9. A wireless device for implementing route transmission of the wireless device based on a single IPv6 address prefix, comprising:
- an interface module, a prefix configuration module, and a data forwarding module, wherein,
the interface module contains at least one WAN interface and one LAN interface, the WAN interface can be connected to Internet through 2G/3G wireless technology, and the LAN interface is connected to a user terminal by means of a cable or Wifi; the prefix configuration module sets apart one 126-bit IPv6 address prefix from a 64-bit IPv6 address prefix obtained from a network side, then allocates the 126-bit IPv6 address prefix to a WAN interface, allocates the 64-bit IPv6 address prefix to a LAN interface, and notifies a user terminal which is connected to the LAN interface of the IPv6 prefix of the LAN interface, so that the user terminal connected to the LAN interface generates an IPv6 address of itself through a stateless address auto-configuration mechanism; the data forwarding module is responsible for identifying and forwarding IPv6 data packages of two subnets of 64-bit IPv6 address prefix and 126-bit IPv6 address prefix. - View Dependent Claims (10, 11)
