Method, terminal and system for processing authentication information

Abstract

The invention discloses a method for processing authentication information. The method comprises the following steps: when point-to-point protocol PPP dialing is performed, a mobile terminal comparesa second access point name APN and second user authentication information obtained during the PPP dialing with a first APN and first user authentication information used during the registration of a mobile network; when it is determined that the first APN and the second APN are the same and the first user authentication information and the second user authentication information are different, themobile terminal initiates a request of releasing a first packet data network PDN connection to the mobile network; and after the mobile network releases the first PDN connection, the mobile terminal establishes a second PDN connection with the mobile network by using the second APN and the second user authentication information. The invention further discloses a mobile terminal and system for processing authentication information.

Description

technical field [0001] The invention relates to the PPP dialing technology in the communication field, in particular to a processing method and terminal for authentication information. Background technique [0002] Point-to-point protocol (Point-to-Point Protocol, PPP) dial-up, also known as network dial-up (Dial UpNetworking, DUN), also known as remote access service (Remote Access Service, RAS) dial-up under Windows system, is to use PPP protocol in the terminal A method for establishing a PPP link between a terminal equipment (Terminal Equipment, TE) and a mobile terminal (Mobile Terminal, MT) to implement dialing. The terminal device here can be a general personal computer, or a device with a built-in embedded Linux system, such as a tablet computer, a home wireless router, etc., and is usually connected to the Internet through non-mobile technology. A mobile terminal may be a mobile phone. For PPP dialing, it needs to be initiated by the terminal device, and then the ...

Problems solved by technology

Therefore, this will lead to the fact that the user authentication parameters set on the terminal device side may not be used, that is, incorrect user authentication parameters may actually be used

[0005] For this problem, this may not have an impact on most networks, but under some operators' networks, due to the strict inspection of user authentication parameters, mobile terminals may be required to use the current Subscriber Identification Module (Subscriber Identification Module) , SIM) card corresponding to the user name, password, authentication method and these user authentication parameters to establish a PDN connection to ensure that the user can access the Internet normally, otherwise problems such as inability to access the network may occur
