Specific embodiment
In the following description, in order that reader more fully understands the application and proposes many ins and outs.But, even if it will be understood by those skilled in the art that many variations and modification without these ins and outs and based on following implementation method, are also the application each claim technical scheme required for protection.
To make the object, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, present system is included in the increase of VPN client 100 and reconnecting event module 101 and reconnecting action module 102, and protocol module 201 is reconnected in the increase of VPN service terminal 200, two ends coordinate, complete network and recover automatically.
Described reconnects the expansion that protocol module is VPN existing protocols, is used to support that VPN Auto-reconnects work, and its workflow is as shown in Fig. 2 the workflow at least increases by two agreements on the basis of being included in VPN communications protocol：
● VPN reconnects Handshake Protocol：The agreement is initiated by client, and after service end receives the agreement, it is the Client for having built connection to identify whether, if not then ignoring；If it is, the connection before release, and set up new VPN connections；And
● VPN reconnects key agreement protocol：After new VPN connections are set up, the symmetric cryptographic key of VPN both sides is updated.
Described reconnects event module, and for monitoring, VPN client is any required to produce the event for reconnecting action：When VPN enters not-connected status, being reconnected event and triggered by VPN client makes it recover or switch into VPN connection status.The wireless access way of intelligent terminal generally has three kinds of VPN connection status and two class networks to reconnect event, and three kinds of VPN connection status include：Not connected (including dormancy) state, WIFI connection status and Cell connection status；Two class networks reconnect event includes network recovery event and network switching event, wherein network recovery event includes dormancy to the event for waking up, the described event that reconnects includes that network is not connected with event, WIFI connection events and Cell connection events, and network recovery event and network switching event.
When the event that reconnects occurs, for example, when VPN disconnections or intelligent terminal dormancy, into not-connected status, then, reconnecting event by two class networks and triggering into other states, as shown in figure 3, the issuable event that reconnects is：
● it is currently not-connected status, receives network recovery event and new network is for Cell is connected, carries out reconnecting action, after reconnecting successfully, into Cell connection status；
● it is currently not-connected status, receives network recovery event and new network is for WIFI is connected, carries out reconnecting action, after reconnecting successfully, into WIFI connection status；
● it is currently WIFI connection status, receives network switching event and new network is for Cell is connected, carries out reconnecting action, after reconnecting successfully, into Cell connection status；
● it is currently Cell connection status, receives network switching event and new network is for WIFI is connected, carries out reconnecting action, after reconnecting successfully, into WIFI connection status；
● it is currently Cell connection status, receives network switching event and new network is for different WIFI are connected, carries out reconnecting action, after reconnecting successfully, into WIFI connection status.
When needing to reconnect action, VPN client needs and VPN service terminal coordinates completion to reconnect agreement first, and then basis reconnects result and carries out the network environment setting of VPN client.Described reconnects action module, and for after generation reconnects event, VPN client and VPN service terminal to coordinate completion to reconnect agreement, then basis reconnects result and carries out the network environment setting of client.As shown in figure 4, the described action module that reconnects generally preserves three kinds of network settings：Network settings when not connected, reconnect preceding network settings, reconnect rear network settings (come from VPN and reconnect agreement).If reconnecting protocol failure, network settings when returning to not connected.If reconnected successfully, return to and reconnect rear network settings.
It should be noted that, the each unit mentioned in each equipment implementation method of the present invention is all logic unit, physically, one logic unit can be a physical location, it can also be a part for physical location, can also be realized with the combination of multiple physical locations, these logic units Physical realization in itself is not most important, and the combination of the function that these logic units are realized is only the key of the technical problem for solving proposed by the invention.In addition, in order to protrude innovative part of the invention, the present invention without introducing above-mentioned each equipment implementation method and the less close unit of the technical problem relation proposed by the invention with solution, but this be not intended that in the absence of the said equipment implementation method and other about implementation unit.
Although by referring to some of the preferred embodiment of the invention, being shown and described to the present invention, it will be understood by those skilled in the art that can to it, various changes can be made in the form and details, without departing from the spirit and scope of the present invention.
