Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: whether the terminal DS-lite technology or the proxy DS-lite technology is adopted, it is necessary to assign a CGN address to the terminal or proxy to establish a tunnel
However, there is no specific CGN address allocation scheme in the prior art

Embodiment Construction

[0050] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0051] figure 1 It is a schematic diagram of the network structure applying the DS-lite technology according to the first embodiment of the present invention. see figure 1, DS-lite is used in wireless communication systems, which can be divided into two modes: terminal and agent. If the terminal, taking the mobile station (Mobile Subscribe Station, MS) 11 as an example, itself has the DS-lite capability, that is, the MS can realize the encapsulation of the IPv4overIPv6 tunnel by itself, and when the MS has an IPv4 service requirement, the MS uses its own IPv6 After the address is encapsulated, the address is sent to the CGN132 in the Network Service Provider (NSP) 13 via the Network Access Provider (Network Access Provider, NAP) 12 through the IPv4overIPv6 tunnel (shown by the thick solid line). The NAP 12 generally...

Abstract

The invention discloses a method for allocating address information, network equipment and a network system. In the method for allocating the address information, a home address authentication authorization charging server (HAAA) acquires trigger information corresponding to a terminal, wherein the triggering information is used for indicating the HAAA to allocate a carrier gradenetwok address translation entity CGN address for the terminal; the HAAA allocates a CGN address for the terminal according to the triggering information; and the HAAA sends the CGN address to the terminal or a lightweight double-stack proxy server. The embodiment of the invention can enable the terminal of the lightweight double-stack proxy server to acquire the CGN address so as to conveniently establish an IPv4overIPv6 tunnel smoothly, thereby realizing that the terminal can acquire the IPv4 service even without an IPv4 address.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for allocating address information, network equipment and a network system. Background technique [0002] A fourth version of the Internet Protocol (Internet Protocol version 4, IPv4) and a sixth version of the Internet Protocol (Internet Protocol version 6, IPv6) exist in the current network technology. A lightweight dual-stack (Dual-stack lite, DS-lite) technology is a solution to the shortage of IPv4 addresses in IPv4-IPv6 coexistence. DS-lite technology includes terminal DS-lite technology and proxy DS-lite technology. DS-lite technology deploys a carrier-grade network address translation entity (Carrier Grade Network Address Translation, CGN) on the network side. An IPv4overIPv6 tunnel is established between them. The outer layer source address of the uplink data tunnel is the public IPv6 address of the terminal, while the inner layer source address is an IPv4 add...
