Abstract

The present application provides a method and a communication device for querying a domain name system. The method includes: a first network element receives a DNS query request from a terminal device, the DNS query request includes a first domain name, and the DNS query request is used to request the first domain name The corresponding IP address; the first network element sends the first request information to the second network element, and the first request information includes the location information of the terminal device and the first domain name; the second network element determines the connection with the first domain name according to the first request information The IP address corresponding to the location of the terminal device is fed back to the first network element, and the first network element sends the IP address to the terminal device. In the method provided by the present application, when the terminal device performs a domain name query, the core network element determines the IP address of the corresponding application server in combination with the location information of the terminal device and the queried domain name. The terminal device obtains the IP address of the application server closest to its own location and accesses the service nearby, which improves the efficiency of the terminal device accessing the service.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201910770920.4 and the application title "Method and Communication Device for Domain Name System Query", which was filed with the Chinese Patent Office on August 20, 2019, the entire contents of which are incorporated herein by reference. middle. technical field [0002] The present application relates to the field of communications, and more particularly, to a method and a communication device for querying a domain name system. Background technique [0003] With the increasing number of users of mobile terminals (such as mobile phones), the business functions supported by various mobile terminals continue to increase. For example, functions such as instant messaging, securities, web browsing, and file download have gradually become the mainstream of terminal devices, especially smartphones. application. In the process of surfing the Internet, the terminal device needs ...
