Data service access method and system

Abstract

The invention discloses a data service access method and system. The method includes the steps: an intelligent domain name server (DNS) is added in a general packet radio service (GPRS) network, the intelligent DNS stores a service domain name which needs to be subjected to proxy processing by a proxy server, and an internet protocol (IP) address of the proxy server is recorded at the same time; a gateway GPRS support node (GGSN) receives a programmed data processor (PDP) context activating request message sent by user equipment (UE), and the IP address of the intelligent DNS is returned to the UE; the UE launches a DNS inquiry request with a domain name of a website to be accessed to the intelligent DNS, the intelligent DNS finds out the domain name is the service domain name which needs to be subjected to proxy processing by the proxy server, the IP address of the proxy server is returned to the UE, and the UE launches a service request with a uniform resource locator (URL) to the proxy server; and the proxy server carries out the proxy processing if finding out proxy processing is needed according to target website information in the request, after the processing is finished, the proxy server sends the service request to a target website server. The data service access method and system can effectively reduce processing pressure of the proxy server and flow amount between the GGSN and the proxy server.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a data service access method and system. Background technique [0002] In a mobile data network, different service domains are usually identified by an access point name (APN, Access Point Name). The terminal determines the way to access the mobile data service by configuring the APN. The operator separates different data communication service networks through the APN. . Through the APN mechanism, operators can implement service control, routing and pipeline value-added capabilities on specific APNs according to business and networking needs, such as: user number insertion, user identification, public-private network address translation and application layer gateway, content accounting fees, Web page adaptation, and content cache acceleration. [0003] figure 1 It is a schematic diagram of the existing APN processing mechanism, such as figure 1 As shown, the APN process...

AI Technical Summary

Problems solved by technology

[0010] 1. There is a high threshold for users: For specific data services, due to business networking and application authentication requirements, user identity information provided by the General Packet Radio Service (GPRS, General Packet Radio Service) network must be used to authenticate users , at this time, the user is required to correctly configure the APN parameters on the terminal in order to access the service platform correctly

[0011] 2. Higher requirements are put forward for mobile terminals: with the intelligentization of mobile terminals, multitasking has become the basic function of new terminals, and the supported mobile services are becoming more and more abundant. In order to ensure the normal use of multiple applications, it is necessary to support Multiple APN concurrency, but most smart terminal platforms (such as: Android, iPhone, etc.) do not support multiple APN concurrency

[0012] 3. It has a great impact on business experience: When users use multiple services on terminals that do not support multiple APN concurrency (such as: Android, iPhone, Windows Mobile, etc.), because they do not support APN concurrency, they often switch to the background The APN of the running application is disconnected, which has a great impact on user experience for applications with real-time access requests (such as: instant messaging, file download) and other applications

[0013] 4. Impact on operators' network planning and traffic management: Operators provide different value-added capabilities on different APNs, and the service experience obtained by users when using different APNs varies greatly, resulting in a large number of APN settings and APN concurrency. , APN usage, and traffic billing-related complaints have caused obstacles to operators' network planning and traffic management

[0014] Therefore, the existing GPRS network routing and APN mechanism have hindered the development of mobile Internet services
