Call management module is used to manage wireless network and connects and parameter configuration.
The firewall configuration module is used to provide the setting to the equipment firewall policy.
See also Fig. 3, this figure is the structured flowchart of middle favourable turn of the present invention, and it mainly comprises usb interface module and Ethernet access module, wherein,
Usb interface module provides the access function to the Seamless Network access device data based on Wi-Fi of the present invention, provides the data routing function that it is linked into local network by middle favourable turn and surfs the Net; This module is driven by usb bus and corresponding function driving-network device interface driving is formed, and in the operating system of transfer pusher side, usb interface module also shows as a network card equipment like this, can be to this network interface card configuration MAC Address and IP address; After carrying out suitable routing configuration, the data routing forwarding that USB interface can be imported has access to spider lines to the Ethernet access module.
The Ethernet access module provides the access function to cable network, and the data that usb interface module inserted by the RJ45 interface are linked into local network and surf the Net.
Utilization is with upper module, and we have preset two kinds and have used scene, are explained as follows:
See also Fig. 4, to be wireline side have access to the scene graph of spider lines by USB interface to this figure, has two kinds of network access modes in this scene, is respectively:
Cable network: by the usb interface module of equipment, via the usb bus of middle favourable turn, the routing forwarding by middle favourable turn is to cable network, the function of surfing the Net of favourable turn self in not influencing simultaneously.
Wireless network: the wireless network access module by equipment is linked into wireless network.
Because there are two kinds of network access modes simultaneously, so the network insertion management is very important, in this scene, use routing configuration instrument to come the connection on the equipment of being linked into is managed based on TCP/IP, user's connection can be configured to cable network also can be configured to wireless network, and this depends on concrete implementation strategy.We provide based on the strategy of flow with based on the strategy of wireless signal strength and have selected for the user.
Strategy based on wireless signal strength: if wireless network signal is very weak or the user by layout setting, data flow can be transmitted the cable network online, via internal gateway, be connected to middle favourable turn by usb interface module, insert 802.3 networks via middle favourable turn, and then the fixed network of access carrier.
Strategy based on flow: if during threshold value setting greater than us via the Wi-Fi amount of user data of wireless network access module access of radio network (can revise), can surf the Net being revised as by cable network greater than threshold value partial data amount, via internal gateway, be connected to middle favourable turn by USB interface, insert 802.3 networks via middle favourable turn, and then the fixed network of access carrier.
See also Fig. 5, to be wireline side have access to the scene graph of spider lines by RJ45 interface interface to this figure, also has two kinds of network access modes in this scene, is respectively:
Cable network: the RJ45 interface by equipment directly is linked into cable network.
Wireless network: the wireless network access module by equipment is linked into the 2G/3G wireless network.
Similarly, because there are two kinds of network access modes simultaneously, so the network insertion management is very important, we use the routing configuration instrument based on TCP/IP to come the connection on the equipment of being linked into is managed, user's connection can be configured to cable network also can be configured to wireless network, and this depends on concrete implementation strategy.We provide based on the strategy of flow with based on the strategy of wireless signal strength and have selected for the user.
Strategy based on wireless signal strength: if wireless network signal is very weak or the user by layout setting, data flow can be transmitted cable network online, via internal gateway, the fixed network of the RJ45 interface access carrier by equipment.
Strategy based on flow: if during threshold value setting greater than us via the Wi-Fi amount of user data of wireless network access module access of radio network (can revise), can surf the Net being revised as by cable network greater than threshold value partial data amount, via internal gateway, the fixed network of the RJ45 interface access carrier by equipment.
Correspondingly, the present invention also provides a kind of method for network access of the Seamless Network access device based on Wi-Fi, see also Fig. 6, this figure is the flow chart of the method for network access of the Seamless Network access device based on Wi-Fi of the present invention, and it mainly comprises the steps:
Step S61, access Wi-Fi user data;
Step S62, carry out routing configuration for the Wi-Fi user data that inserts according to current access Wi-Fi user's total amount of data or current link-quality or user's Route Selection instruction;
Step S63, described Wi-Fi user data is linked into wireless network by Radio Link, perhaps, is linked into cable network by wire link according to described routing configuration result; Described wireless network is the 2G/3G wireless network.
Wherein, being linked into cable network by wire link specifically comprises:
The Wi-Fi user data that inserts is linked into middle favourable turn by USB interface, provides the data routing function that described user data is linked into cable network by middle favourable turn; Perhaps, the Wi-Fi user data that inserts is linked into cable network by the RJ45 interface.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
