The realization of the present invention, being suitable for Android provides and installs an application program, it start, in the system of acquisition In the case of highest weight limit or open system highest weight limit, and provide interactive function to system, it is achieved the control needed for this method System.

As it is shown in figure 1, a kind of intelligent terminal network collocation method of the present invention, comprise the steps S11-S13:

Step S11, foundation meet the network group of WiFi P2P specification to complete opening of the hotspot pattern of this intelligent terminal Dynamic so that it is with the station mode of this intelligent terminal deposit work.

Described hotspot pattern can be set up in theory by focus process Hostapd of android system, but, In actual measurement, during hostapd process initiation, website process can be automatically switched off, cause intelligent terminal cannot simultaneously work in focus mould Under formula and station mode, thus, then use the mode setting up network group voluntarily, sending out of this fault can be prevented effectively from Raw.

According to the specification of WiFi P2P agreement, can make multiple intelligent terminal's group a network group, at this network group In group, have and only one of which service end role, the rest is client role.Described service end and two kinds of roles of client, In the present invention, for two intelligent terminal with WiFi P2P agreement institute specification, wherein, as the intelligence of client The chip module of energy terminal works under the P2P-Client pattern of this agreement institute specification, i.e. shows as client role；And with The intelligent terminal of the relative present invention then work under P2P-Group Owner (P2P GO) pattern of this agreement institute specification, I.e. show as service end role.

In android system, encapsulate point-to-point connection management a class, i.e. WiFiP2pManager, as the term suggests, should Class is i.e. for managing the point-to-point connection between Android terminal according to the specification of WiFi P2P agreement.Such constructs one The individual method function for setting up described network group, concrete reform is WiFiP2pManager.createGroup (wifip2pmanger.chanenl, wifip2pmanager.ActionListener), calls the method, can create one Focus, makes intelligent terminal start hotspot pattern, and self is set to service end, and the focus thus created can also be for not propping up The traditional WiFi equipment holding WiFi P2P agreement is attached thereto.The network group being consequently formed, it is possible to use such the opposing party Method function: requestConnectionInfo (wifip2pmanger.chanenl, Wifip2pmanager.ActionListener) go to obtain detailed link information.This wifip2pInfo link information bag Contained have the address groupOwnerAddress of group person namely service end and one go to illustrate whether current device is this The mark isGroupOwer of the owner of p2p group, the client of a p2p therefore can be with p2p group owner by one Socket connection communicates.

Under Android operation system default situations, the WiFi chip module not allowing for same intelligent terminal works simultaneously Under client and service end both of which, but, but can solve this problem by creating described network group voluntarily, its The calling of middle createGroup () function plays the effect of key, and it completes the startup of hotspot pattern of this intelligent terminal.

Due to the present invention it is important that hope solves the WiFi function visit of the smart machine allowing client pass through service end place Ask the netconfig problem of outer net.On the premise of not considering that client connects outer net voluntarily, outside this intelligent terminal is able to access that Net, is the premise of the client-access outer net accessing present networks group.It is therefore advantageous to mode in, be to make this intelligent terminal exist Before completing the startup of above-mentioned hotspot pattern, just have been turned on station mode.

The station mode of android system to be started, can arrange manually opened on page by user in system or pass through The website process of system is set up.Described website process, the wpa_supplicant that refering in particular to android system self provides enters Journey, wpa_supplicant is originally open source projects source code, adds android mobile platform, be primarily used to after being revised by Google Support WEP, WPA/WPA2 and WAPI wireless protocols and encrypt certification, and actual job content is by socket (no Pipe is that wpa_supplicant uses socket communication with upper strata or wpa_supplicant with driving) and drive on mutual Count off is according to user, and user can send commands to wpa_supplicant transfer driving by socket and to grasp WiFi chip Make.Briefly, wpa_supplicant is exactly that WiFi drives and the terminal of user is additional props up agreement and encryption certification Hold.Wpa_supplicant source program after compiling is it can be seen that two main performed instrument: wpa_ Supplicant and wpa_cli.Wpa_supplicant is kernel program, and it services and client exactly with the relation of wpa_cli The relation of end: running background wpa_supplicant, uses wpa_cli to search for, arrange and connect network.

An example utilizing wpa_cli to connect to complete network presented below understands this for those skilled in the art's reference Invention, but should not be construed as the restriction of the realization to the present invention.

Network connecting function to be realized, it is necessary first to run wpa_supplicant program to load basic function；

Perform :/system/bin/wpa_supplicant-d-Dwext-iwlan0-c/data/misc/wif i/wpa_ supplicant.conf

Wherein:

In like manner, above parameter list also can be obtained from Android official by public approach, only for reference, pardons and does not repeats.With Lower one is utilized to illustrate how that realizing network connects for connecting the instantiation of AP without encryption:

> add_network (network ID will be shown, it is assumed that return value is 0)

>set_network 0ssid"666"

>set_network 0key_mgmt NONE

>enable_network 0

>quit

Recycling one is illustrated for the instantiation connecting the AP of WEP encryption:

> add_network (assuming that network ID returns 1)

>set_network 1ssid"666"

>set_network 1key_mgmt NONE

>set_network 1wep_key0"your ap password"

>enable_network 1

Example as the AP connecting WPA-PSK/WPA2-PSK encryption is as follows:

> add_network (assuming that network ID returns 2)

>set_network 2ssid"666"

>set_network 2psk"your pre-shared key"

>enable_network 2

Arriving this, wifi module just can connect AP.

It is above being realized the connection of wifi network by command-line tool wpa_cli.It is of course also possible to pass through wpa_ The configuration file of supplicant realizes connecting.

Might as well look back again above run wpa_supplicant time perform order:

/system/bin/wpa_supplicant-d-Dwext-iwlan0-c/data/misc/wifi/wpa_ supplicant.conf

We add-c/data/misc/wifi/wpa_supplicant.conf upon execution, so can The AP connected is arranged with in certain form write wpa_supplicant.conf configuration file.Such as:

Ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system Update_config=1

Network={

Ssid=" my access point "

Proto=WPA

Key_mgmt=WPA-PSK

Psk=" you pass words "

}

Visible, even the station mode of call site process initiation intelligent terminal's WiFi chip module, it is possible to by with Upper utilization instruction, utilization two kinds of different modes of configuration file, realize being controlled described website voluntarily by program process and enter The unlatching of journey, so that intelligent terminal works under station mode.

As can be known from the above analysis, the present invention can activate the station mode of intelligent terminal by various ways, and passes through Calling the createGroup method of point-to-point connection management class to activate the hotspot pattern of intelligent terminal, both patterns are permissible And be stored in Android intelligent terminal.So that intelligent terminal can utilize its station mode accessing external network, utilize heat simultaneously One mininet of dot pattern construction.

For making above-mentioned concurrent state be physically easier to perform, embody more preferably Consumer's Experience, the program process of the present invention Can be the most perfect by user interface being designed to this.

User interface refers to and is implemented for man-machine interaction and is able to receive that the display interface of user's control instruction, example As, can be android system arrange in the page option (or button, is added wherein by described application program, under With), it is also possible to it is an option from the informing or interaction page of desktop exhalation, it is also possible to be described application program An option in the page that one moving component is constructed.

The present invention is preferably as follows two ways, for receiving described control instruction:

One, by providing single control button in user interface, receives described control instruction for one-touch, This mode is easy to user and is realized operating in a key.

Its two, by providing control button respectively, with the most right at user interface correspondence hotspot pattern and station mode Different key is answered to produce the corresponding control instruction starting corresponding pattern.

The control button provided according to above mode, generally these buttons can be preferably provided at system desktop informing At list, or provide in the way of desktop suspended window, be both easy to user's touch-control and controlled, the most do not affected user's visual effect, when Activate when the most also can open WiFi button as the default feature of system with user.It is also preferred that the left described application program can be by Self it is set to self-starting item so that during system start-up, described button can be loaded voluntarily, consequently facilitating user operation.

When user is by described user interface, after the control button described in touch-control, just produce corresponding control instruction, This control instruction will be received by the process of described application program, thus the control hotspot pattern of correspondence and/or station mode are opened.

Specifically, user both can open hotspot pattern and station mode by single control button simultaneously, it is possible to Open with the button corresponding with both of which by two, essentially provide multiple operation change case.Corresponding these become Change, illustrate further below.

If user interface provides single control button, user triggers its user instruction by this single control button, this Place just can first call createGroup () and create focus.Then, the program process of the present invention starts this website the most voluntarily Process, the most just can realize both of which and deposit.Otherwise, it is also possible to leading initiating station point process, after it completes to open, Go again and open hotspot pattern with reference to above-mentioned example.It is to say, the control instruction caused corresponding to single control button, can be with Hotspot pattern and the boot sequence of station mode described in different embodiment flexible arrangement.

And correspondence user interface provides different control buttons, for characterizing the example opening different patterns respectively, then Can click on the different order controlling button by user and sequentially open corresponding pattern, this measure has no effect on the enforcement of the present invention.

In preferred scheme, it is recommended that preferentially allow station mode open prior to hotspot pattern, guaranteeing that this intelligent terminal can In the case of connecting outer net, provide access function to other intelligent terminal, some idle works can be exempted, the most energy-conservation.

As can be seen here, after station mode and hotspot pattern being sequentially activated, coexisting of both of which can just be realized.At this On the basis of, the program process of the present invention can export some object informations to user interface, to inform this intelligence of user eventually The concurrent state that end currently coexists already at hotspot pattern and station mode.As for the expression-form of described object information, Both can be to be shown in informing by system message, it is also possible to pop-up shows on the table, more excellent mode can be to adjust With default third party's icon, for characterizing the bimodulus shape that this intelligent terminal is in hotspot pattern and station mode coexists State, is shown to this third party's icon in the system mode hurdle of user interface so that user is easier to know that corresponding result is believed Breath.

Step S12, with system highest weight limit call network guard process amendment network configuration sharing information make connection focus Network between pattern with station mode is connected.

Relate to the operation that network guard process is directly invoked, according to the specification of Android, need acquisition system High authority, thus, on the premise of acquisition android system highest weight limit or android system have opened highest weight limit, Can be by described network guard process be called, amendment relates to the configuration information that network is shared, i.e. network altogether whereby Enjoy configuration information, in order to the network between connection hotspot pattern and station mode is connected, client can be come by service end Access outer net.

Described network guard process, i.e. the abbreviation of Netd, Network Daemon.Netd is responsible for relating to physics with some The functional realiey that the network operation of port is relevant, such as bandwidth control (Bandwidth), network address translation (NAT), Ge Renju Territory net (pan), PPP links, soft-ap, the shared verification (Tether) etc. involved by the hotspot pattern of this intelligent terminal Deng ... all it is organized under netd file directory according to module (.cpp+.h).

Four major parts of the basic framework that Android Netd is relevant:

(1) Linux Kernel is for detecting all events that network is relevant.

(2) Netd is as the bridge communicated between Kernel (inner nuclear layer) and Framework (ccf layer).

(3) ccf layer operation Netd, sends operational order to Netd.

(4) application layer is mutual with ccf layer, carries out the manipulation of network for user.

Android is that Netd provides testing tool, i.e. a ndc, and its major function has:

Monitor event in Netd.

Support that sending commands to Netd by order line goes to perform.Ndc realizes principle, is to be positioned at netd on connecting to enter " netd " in journey monitors socket, then receives information from Netd or sends commands to Netd.

As can be seen here, network guard process can be driven to perform dependent instruction, in the present invention, it is achieved to net by ndc The function of the amendment of network configuration sharing information, just may utilize ndc order and implements.

Observation process please also refer to as follows android system being implemented:

First, by analyzing, after finding that createGroup () creates focus, although can be connected by client, but its As follows for the parameter of configuration process DNSmasq to user feedback DHCP configuration information:

/system/bin/dnsmasq--keep-in-foreground--no-resolv--no-poll--dhcp- Auth oritative--dhcp-option-force=43, ANDROID_METERED--pid-file--dhcp-rang e =192.168.42.2,192.168.42.254,1h--dhcp-range=192.168.43.2,192.168.43.254, 1h--dhcp-range=192.168.44.2,192.168.44.254,1h--dhcp-rang e=192.168.45.2, 192.168.45.254,1h--dhcp-range=192.168.46.2,192.168.46.25 4,1h--dhcp-range= 192.168.47.2,192.168.47.254,1h--dhcp-range=192.168.48.2,192.168.48.254,1h-- Dhcp-range=192.168.49.2,192.168.49.254,1h

There it can be seen that with addition of the control option i.e. dhcp-option-force forcing configuration sequence to be 43 =43, ANDROID_METERED, official's lexical or textual analysis of sequence number 43 is manufacturer's specified option, is used for representing that being currently connected as charging connects Connecing, in this case, the outer net that can not utilize service end is connected by client, in order to avoid producing enormous expenditure.But, this set Meter logic is to provide, by being connected by the charging of operator, the outer net service that accesses with service end, but service end exists with WiFi Station mode set up free outer net connect situation, not by Android compatibility.

Then, by analyzing in Android official document the source generation for TetherController (shared control unit) Code understands, and in this case, at this, ANDROID_METERED has been carried out specification, but, but have no setting of default gateway Put.

And to client is analyzed, from core.java.android.net.DhcpInfoInternal namely Dhcp client over there, utilizes following code implementation to detect:

Above analysis shows, as client to be made connects outer net by service end, needs to avoid above-mentioned control choosing The impact of item.

And then, by analyze this intelligent terminal hotspot pattern open before and open after packet forward switch and data Packet filtering table i.e. iptables, it has been found that affect the factor of client online.

Specifically, switch is forwarded for packet, it is found that cat/proc/sys/net/ipv4/ip_forward Result be 1 rather than 0, thus echo " 1 " >/proc/sys/net/ipv4/ip_forward can be passed through in theory Enable changes this switch and arranges so that it is open packet forwarding capability.But, in this case, owing to being subject to The impact of iptables, even if making above-mentioned change, client carries out extranet access and still fails to unimpeded.When intelligent terminal's The interface corresponding to p2p0 mark under hotspot pattern receives packet, though route can be searched, and is dealt under its station mode Interface corresponding to wlan0 mark, but can be abandoned by the filtering rule of iptables.

For iptables, finding that it affects of both existing, the first wherein includes the data of interface p2p0 The rule that abandons of bag, it two is the NAT rule that intelligent terminal is mapped to public network by shortcoming.For the former, following finger can be passed through Order processes: iptables-D FORWARD 4, i.e. deletes the 4th rule in forward, namely natctrl_FORWARD rule Then.At this time receive bag as p2p0, can send from wlan0.But the source ip of this bag is Intranet ip.Accordingly, it would be desirable to it is right The latter processes as follows: iptables-t nat-A POSTROUTING-o wlan0-j MASQUERADE, i.e. to iptables Filter table increases a nat rule, after interpolation, on another mobile phone, just can lead to outer net ip with ping.By client to The connection of outer net, the most unimpeded.Naturally, and combining practice analysis, gateway is the most correctly configured.

By above-mentioned process, the problem that only address only IP layer, for the function of dns resolution, the most unrealized.Enter one Walking the configuration parameter by analyzing DNSmasq, find this carry--no-resolv option, this option causes impact visitor just Family end obtains the reason of correct dns resolution.Thus, it is possible to by amendment startTethering method or increase by StartTetheringWithDns () method, removes--no-resolv parameter.Completing these operations, client arrives through service end Outer net, specific to the access of WWW based on domain name, the most unblocked.

Above, generally, the present invention is for realizing client by service end access outer net by ndc tool drives net What network finger daemon was made relates to the amendment of network configuration sharing information, is mainly concerned with following aspect:

The packet forwarding capability that one, the network opened between connection hotspot pattern and station mode are connected: concrete table It is now 1 to open for its parameter can be arranged by echo instruction.

Two, revise the setting of the Packet Filtering table being connected for the network between unimpeded hotspot pattern and station mode Content: be embodied in and iptables form is removed corresponding filtering items and interpolation NAT map record.

Three, remove client shared verification and limit the option resolving DNS: be embodied in and can pass through shared control unit (TetherController) method is removed--no-resolv option.

As can be seen here, by above-mentioned method, just can make the intelligent terminal of the present invention realize connecting its hotspot pattern and its Network between under station mode connects, and provides the service of accessing external network for client.

Above by the announcement analysis process to the system principle of Android, disclose the principle that realizes of the present invention, and carry Supply how to revise a kind of embodiment of network configuration sharing information, in addition, revise net also by following mode Network configuration sharing information:

This mode specifically, is i.e. called ndc instrument with system highest weight limit and is realized repairing by network guard process The mode changed, refers to following code and explanation thereof:

ndc ipfwd enable

ndc tether dns set 0 114.114.114.114

// if it fails, generally mean that and above have manual operations to cancel the most completely.Performing ps | grep dnsmasq is first Positive closing configuration process.If also remaining process, such as:

shell@CP8681_A01:/#ps|grep dnsmasq

dhcp 3557 325 10272 740 001a0338b66f61ac S/system/bin/dnsmasq

// execution kill 3557 kills, then

Ndc tether stop, // stop sharing

Ndc tether start 192.168.49.2 192.168.49.254//startup is shared, and configures the network segment

Ndc tether dns set 0 114.114.114.114//DNS is set

Ndc nat enable p2p0wlan0 0//interpolation NAT rule

After tested, the effect that above code is risen is consistent with the manual modification process that top is disclosed, and makees through thus section code With, packet forwarding capability is opened, and iptables filter table obtains correct configuration, and dns resolution function also obtains correct Safeguard.Therefore, the application program of the present invention after starting hotspot pattern, can perform this under system highest weight limit state Section code, just achieves the correct amendment to network configuration sharing information, and client just can be surfed the Net by service end.

Most android system intelligent terminal, due to the restriction of manufacturer, does not open its system highest weight limit, or Unsuccessful by ROOT, for this situation, above instruction with NDC directly drives network guard to carry out implementing network configuration sharing letter The operation of the amendment of breath can not be successful.Accordingly, it would be desirable to look for another way.

The mode of a kind of improvement is that the code wrap expressed with NDC above is become a method function (configuration interface), right The Open Source Code file i.e. WifiP2pServiceImpl.java of WiFiP2pManager class modifies, due to The function that WifiP2pServiceImpl.java can directly be derived by mNwService realizes those ndc orders, because of, Can inside increase the method function, and derive to the use of WiFiP2pManager class, so, the application program of the present invention is only Directly need to call this configuration interface by WiFiP2pManager class, the amendment to network configuration sharing information can be implemented, and Acquisition without Help of System highest weight limit.

As can be seen here, described network guard process is controlled in the way of amendment network configuration sharing parameter by ndc order Also it is diversified.

By implementing above-mentioned multiple control modes, the network between the hotspot pattern of service end and station mode all can be made Connection interconnects, and the problem of route has solution therewith.

Step S13, access after described network group in client, set up this client and maintained with by described station mode The connection of outer net.

After the network group that client access service end provides, DHCP request will be sent to service end, joining of service end Process of putting reads the correct network configuration sharing information after above-mentioned amendment, feeds back to client.Client completes accordingly After the network settings of self, just can be through accessing outer net as the focus interface of service end intelligent terminal of the present invention, site interface. For this intelligent terminal, when it receives the packet of client-access outer net, this packet is forwarded through described website The path transmission of pattern gives described outer net；When it receives the packet of extranet access client, it is forwarded through described heat The path transmission of dot pattern gives this client.

Further, for improving the function of the program process of the present invention, subsequent step can be increased: this step responds In exiting the user instruction of shared verification, the network configuration sharing information described in recovery.

Specifically, the application program of the present invention is referred to aforesaid mode, provides one to share to user interface The control button of net, also may be used as continued to use the above-mentioned final election control operation controlling button providing user interface.When When this control button is triggered, just producing described user instruction, acted on by this user instruction, the present invention just can implement to disconnect Described hotspot pattern, disconnects external connection the most automatically.

Further, it is possible to use mode the most thoroughly, the network configuration sharing letter in advance aforementioned processing process produced Breath is cleared up, such as, and the ndc instruction refering to following:

Ndc ipfwd disable//closedown packet forwarding capability

Ndc tether stop//stopping online sharing functionality

Ndc nat disable p2p0wlan0 0//closedown NAT mapping function

Perform above-mentioned order by the program process of the present invention, just can pass through SOCKET port controlling network guard Process performs corresponding function, thus avoids the aforesaid potential shadow using network configuration sharing information to the machine and being brought Ring.Could be aware that, the program process of the present invention directly invokes the above-mentioned network guard process described in order control Premise be obtained system highest weight limit.

In like manner, according to above-mentioned building method function the example that is implanted in WiFiP2pManager, herein Thrashing code can be configured to method function (interface of clearing up and discharging) completely in the same way, add WiFiP2pManager class to Code file in, export as such corresponding member function, follow-up directly called this by the program process of the present invention Interface of clearing up and discharging can perform, without considering currently to have obtained system ROOT authority.

In sum, the method for the present invention solves Android intelligent terminal and opens hotspot pattern and station mode simultaneously Technical barrier, and allow the client accessing the network group under its hotspot pattern via its station mode corresponding outside Network interface accesses outer net.

According to the modularized thoughts of computer software, the present invention also provides for a kind of intelligent terminal, and this intelligent terminal includes building Vertical unit 11, dispensing unit 12 and communication unit 13, the concrete function that unit introduced below is realized:

Described sets up unit 11, meets the network group of WiFi P2P specification to complete this intelligent terminal's for setting up The startup of hotspot pattern so that it is with the station mode of this intelligent terminal deposit work.
