Problems solved by technology

[0005] First, the IOS VPN interface Network Extension (NE) is relatively immature
NE was only provided to developers after IOS8.0+ in September 2014, and there were many problems in the early stage of NE interface opening, and the relevant research work and development experience were very lacking
[0006] Second, the IOS system has restrictions on background resident services
Therefore, it is necessary to implement background resident services to realize network monitoring, VPN interruption and recovery, but the IOS system permissions only allow background resident services to be enabled for audio and video, location, and voice calls
[0007] Third, the defects of the IOS system network monitoring method

Embodiment Construction

[0056] The present invention provides a network perception and seamless switching method suitable for IOS VPN, such as figure 1 As shown, the method includes: a socket state acquisition module, a communication interface state acquisition module, a network perception module and a seamless switching module;

[0057] S101, the socket status acquisition module acquires the status of creating a VPN socket, and the communication interface status acquisition module acquires the communication interface status of the IOS mobile terminal;

[0058] S102. The communication interface state acquisition module detects that the network state of the network communication interface changes, and returns the identified network state change information of the network communication interface to the network perception module;

[0059] S103, the network perception module processes the network state change information experienced by the communication interface of the IOS mobile terminal;

[0060] S10...

Abstract

The invention provides a network awareness and seamless switching method for an IOS VPN. According to the method, network event awareness, network state judgment and VPN socket event decision making are achieved according to the network communication interface state and the VPN socket state, seamless switching of the IOS VPN in a complex network environment is guaranteed, the stability and the mobility of the IOS VPN are guaranteed, and the user experience of the IOS VPN is improved. The network awareness and seamless switching method for the IOS VPN can achieve network state monitoring, network event judgment, VPN socket state monitoring and VPN socket event determining on the IOS VPN and support network awareness on the work context environment and seamless switching on a secure communication tunnel and is suitable for secure, reliable and stable communication of the IOS VPN in the complex network environment.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a network perception and seamless switching method suitable for IOS VPN. Background technique [0002] Compared with traditional VPN, the network environment of mobile VPN is more complex and changeable, and it always faces network events such as network interruption, network recovery, and network switching. Network interruption events include from Wi-Fi network or mobile cellular network to no network, network recovery Events include going from no network to Wi-Fi network to cellular mobile network, and network handover events include going from Wi-Fi network to mobile cellular network. Random and frequent network events can easily lead to abnormal or even errors in network sockets, resulting in failure of mobile VPN communication or even abnormal communication of mobile terminals. Due to the consideration of transmission efficiency and communication overhead, most VPNs are...
