Embodiment Construction

[0023] The invention discloses a mobile terminal, in particular a method for automatically assigning IPv6 and DNS addresses of a wireless data card.

[0024] For wireless data cards that support IPv6 functions, when using stateless automatic address assignment, the network has two IPv6 address assignment methods, one is to assign a unique network prefix address (Prefix Address), and the other is to assign a unique network interface identifier (IID Address). For the dial-up of the Ethernet link mode, after the data card is assigned an IPv6 address, the data card and the host will use stateless auto-configuration (SLAAC) for IPv6 address negotiation, and the host obtains the network prefix from the data card through a router advertisement message After the address, a globally unique IPv6 address will be dynamically generated. In this way, the host can use the automatically generated global IPv6 address to normally access the IPv6 network under the network with the prefix addres...

Abstract

Proposed are a mobile terminal address allocation method, a mobile terminal and a system. The method comprises: a host using a stateless address autoconfiguration function to generate a global IPv6 address; the host acquiring a DNS address from a mobile terminal via host-side software and setting same; the host-side software sending a packet to a DNS server to confirm whether the IPv6 address of the host is correct, and if it is correct, IPv6 address allocation being completed; and if it is not correct, deleting the IPv6 address which has already been configured by the host, and the host re-acquiring an IPv6 address allocated by a network from the mobile terminal and then allocating same to the host. The adoption of the method, mobile terminal and system of the present invention ensures that a mobile terminal can normally perform data transmission under two kinds of IPv6 networks, improving the compatibility of the mobile terminal with networks with different IPv6 address allocation mechanisms.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a mobile terminal and an automatic address allocation method thereof. Background technique [0002] An IPv6 address is composed of a prefix and an interface identifier, in which the upper 64 bits are the address prefix and the lower 64 bits are the interface identifier. In the 3GPP specification, the interface identifier and address prefix are allocated by the network in two stages. In the first stage, the data card obtains its interface identifier from the GGSN (Gateway GPRS Support Node). In this stage, the PDP (Packet Data Protocol ) to complete the process of context activation. In the second signaling stage, the data card obtains the address prefix required by the global IPv6 address from the GGSN by using routing request (RS) and routing advertisement (RA) messages. There are two types of IPv6 addresses for hosts. One is the link-local address, whic...
