Abstract

The invention discloses a domain name resolution method, a domain name resolution device and a domain name resolution system during traffic offloading. The method comprises the following steps that: an internet protocol (IP) address of a first domain name resolution server is configured in wireless access network equipment, wherein the first domain name resolution server is positioned in public internet; the wireless access network equipment receives an address distribution message which is sent to a terminal by a core network, the address distribution message carries the IP address of a second domain name resolution server, and the IP address of the first domain name resolution server replaces the IP address of the second domain name resolution server to obtain a second address distribution message; and the wireless access network equipment sends the second address distribution message to the terminal, and the terminal performs domain name resolution according to the second address distribution message. By adoption of the method provided by the invention, during the traffic offloading, a user terminal can smoothly access a network in the conventional net mode without any modification, and a user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for domain name resolution during traffic unloading. Background technique [0002] In the wireless communication access network, when the user terminal is configured to perform data services in the Internet mode, the user obtains complete Internet access rights. An access point (Access Point Name, APN) is a way for a user terminal to access the Internet. For example, China Mobile Net (CMNET) is the name of an access point used by mobile phones to access the Internet. It is the name of the access point (Access Point Name, APN) of China Mobile's GPRS network, through which CMNET can obtain full Internet access rights and provide NAT services. [0003] Domain Name System (DNS), the role of the DNS server on the Internet is to convert domain names into IP addresses that can be recognized by the network. Internet websites exist in ...
