Detailed description of the invention
For the technical scheme making to present invention solves the technical problem that, adopting and the technique effect reached clearly, below in conjunction with accompanying drawing, the technical scheme of the embodiment of the present invention is described in further detail, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
As it is shown in figure 1, the present invention provides the method for attachment of a kind of LAN.Described method of attachment is performed by first terminal and at least one second terminal.Described first terminal and each second terminal are communicated with one another by wifi hotspot, and to constitute be server, each second terminal by described first terminal be the LAN of client.Wherein, described first terminal can forward the data that each second terminal is transmitted.At this, described first terminal and the second terminal all comprise wireless communication module.Described first terminal and the second terminal include but not limited to: mobile phone, notebook computer, panel computer etc..
The method of attachment of described LAN is as described below.
In step s 11, described first terminal sets up wifi hotspot, and based on the access request of the client monitored, builds the LAN with client.
Specifically, the user using first terminal can select to build wifi hotspot option in arranging interface, the instruction of wifi hotspot is set up in the acquisition that described first terminal is corresponding, and according to the server of the current connected wifi hotspot of described instruction periodic monitor or current connected wlan network.After user closes server or the current connected wlan network of current connected wifi hotspot, described first terminal starts wifi hotspot oracle listener automatically, and monitors the access request of client.
At this, described first terminal receive described set up wifi hotspot instruction time, whether the wireless communication module (i.e. wifi communication module) detecting self meets the condition of default structure wifi hotspot (if wireless communication module is double frequency wifi communication module)；If meeting, then prompting user not creates the server of wifi hotspot；Otherwise, then the steps such as the server of the current connected wifi hotspot of periodic monitor or current connected wlan network are performed, until monitoring the access request of client.
Hereafter, using the user of the second terminal to select the wifi hotspot corresponding to first terminal described in wifi list, described second terminal correspondence performs step S21.
In the step s 21, described second terminal is based on selected wifi hotspot, and application accesses the server of described wifi hotspot the LAN of structure and described server.
Specifically, described second terminal sends access request to described first terminal, and by, after certification, with described first terminal for server, and constituting a LAN with described first terminal and the second terminal.
Described first terminal is based on the second terminal distribution IP that the access request received is correspondence, and preserves IP list.Meanwhile, described first terminal also performs step S12.
In step s 12, described first terminal is monitored and adds up and the network connection state of each second terminal in described LAN.
Specifically, described first terminal periodic training in LAN each second terminal send network connection information, if feedback information can be received, then determine and the second corresponding terminal communication, otherwise, then determine that the network with the second corresponding terminal connects to disconnect, i.e. the non-suspension state of network connection state.
Or, facility information (such as MAC Address etc.) in each received access request is mated by described first terminal with the facility information in the IP address list safeguarded, if can match, it is determined that be once in suspension state with the second corresponding terminal.
In described first terminal statistics preset duration, whether the ratio of each described network connection state interruption net state reaches the proportion threshold value preset, and if so, then performs step S13, if it is not, then continue monitoring.
Preferably, the on off operating mode of each second network with current local network is not only monitored and added up to described first terminal, and during herein in connection with history as server, the suspension state with each client determines that self is if appropriate for doing server.
Specifically, the network connection state added up is preserved by described first terminal；Interrupt the ratio of net state in conjunction with in each web-based history connection status preserved and whether reach, with the network connection state of current statistic, the proportion threshold value preset.
At this, described first terminal is after having added up the network connection state of preset duration, the network connection state calculating ratio and current statistic that each web-based history connection status interrupts net state interrupts the ratio of net state, and according to default weight, two obtained ratio values are weighted statistics, normalized etc., and statistical result is compared with the proportion threshold value preset, if beyond described proportion threshold value, then perform step S13, otherwise, then continue monitoring.

At this, the process that described second terminal sets up wifi hotspot is similar with step S11.
Such as, described second terminal is according to described server handover request, the server of the wifi hotspot that periodic monitor is current connected.After user closes the server of current connected wifi hotspot, described second terminal starts wifi hotspot oracle listener automatically, and monitors the access request of described first terminal.
At this, described second terminal is when receiving described server handover request, and whether the wireless communication module (i.e. wifi communication module) detecting self meets the condition of default structure wifi hotspot (if wireless communication module is double frequency wifi communication module)；If meeting, then prompting user not creates the server of wifi hotspot；Otherwise, then feedback server handoff response, and the step such as the server performing the current connected wifi hotspot of periodic monitor.
In step S14, described first terminal, based on the server handoff response fed back, accesses in one of them wifi hotspot constructed by the second terminal corresponding to server handoff response.
When server handoff response is one, described first terminal accesses in this wifi hotspot constructed by the second terminal corresponding to server handoff response.Wherein, described first terminal accesses the mode of wifi hotspot can be identical with the mode of the wifi hotspot constructed by the second terminal access first terminal, is not described in detail in this.
IP address is redistributed in order to avoid in the LAN that the terminal comprising more than three is constituted, and prevent the server that multiple client becomes server and produces in same LAN from competing, during switching server, described second terminal is not direct construction wifi hotspot after sending server handoff response, but carries out following interactive step with first terminal: (being all unillustrated)
In step S15, described first terminal selects the server handoff response being initially received, and each client and own IP address in the described LAN preserved are sent to the second terminal corresponding to selected server handoff response.
The IP address list that the second corresponding terminal provides based on described first terminal, first carries out step S22, then performs step S23, namely indicate each terminal switching server corresponding to described IP address list.
Specifically, described second terminal, after establishing wifi hotspot, sends switching command according to described IP address list to other second terminals and first terminal.Receive each terminal of described switching command and update the IP of server, the even MAC Address etc. that self connect, to rebuild LAN.
