Abstract

The invention provides a domain name system query method and a communication device. The method comprises the steps that a first network element receives a DNS query request from a terminal device, the DNS query request comprises a first domain name, and the DNS query request is used for requesting an IP address corresponding to the first domain name; the first network element sends first requestinformation to the second network element, wherein the first request information comprises position information of the terminal device and a first domain name; and the second network element determines an IP address corresponding to the first domain name and the position of the terminal device according to the first request information and feeds back the IP address to the first network element, and the first network element sends the IP address to the terminal device. According to the method provided by the invention, when the terminal device performs domain name query, the core network element determines the IP address of the corresponding application server in combination with the position information of the terminal device and the queried domain name. Therefore, the terminal device obtains the IP address of the application server closest to the terminal device and accesses the service nearby, and the service access efficiency of the terminal device is improved.

Description

[0001] This application claims priority to a Chinese patent application filed with the China Patent Office on August 20, 2019, with application number 201910770920.4 and titled "Method and Communication Device for Domain Name System Inquiry", the entire contents of which are hereby incorporated by reference in this application middle. technical field [0002] The present application relates to the communication field, and more specifically, relates to a domain name system query method and a communication device. Background technique [0003] With the continuous growth of the number of mobile terminal (such as mobile phone) users, the business functions supported by various mobile terminals are increasing, such as instant messaging, securities, web browsing, file download and other functions have gradually become the mainstream of terminal devices, especially smartphones. application. In the process of surfing the Internet, the terminal device needs to query the domain name ...
