Then, revise the configuration file of this configuration process so that it is comprise the control option forcing client executing static routing configuration, force client according to the static routing data that described option is 121 in the routing configuration information of service end offer, self to be configured.
After closing described configuration process, and then its configuration file dnsmasq.conf is modified, such as:
Dnsmasq process of stopping # reads the domain name file of other any such as/etc/resolv.conf
no-resolv
Port=0
# network card binding
Interface=wlan0
# specifies initial address, termination address and lease time
Dhcp-range=10.15.0.3,10.15.0.20,12h
# is sent to the domain name server address of client
Server=114.114.114.114
# forces routing configuration, arranges control option and sets option as 121
Dhcp-option-force=121,192.168.1.0/24,10.15.0.1
Dhcp-option-force=33,192.168.1.0,10.15.0.1

In like manner, above parameter list also can be obtained from Android official by public approach, only for reference, pardons and does not repeats.Illustrate how that realizing network connects following with one for connecting the instantiation of the AP without encryption:
> add_network (network ID will be shown, it is assumed that return value is 0)
>set_network0ssid"666"
>set_network0key_mgmtNONE
>enable_network0
>quit
Recycling one is illustrated for the instantiation connecting the AP of WEP encryption:
> add_network (assuming that network ID returns 1)
>set_network1ssid"666"
>set_network1key_mgmtNONE
>set_network1wep_key0"yourappassword"
>enable_network1
Example as the AP connecting WPA-PSK/WPA2-PSK encryption is as follows:
> add_network (assuming that network ID returns 2)
>set_network2ssid"666"
>set_network2psk"yourpre-sharedkey"
>enable_network2
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 realize connecting by the configuration file of wpa_supplicant.
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 the AP's that will connect is arranged with in certain form write wpa_supplicant.conf configuration file.Such as:
Ctrl_interface=DIR=/data/system/wpa_supplicantGROUP=syst emupdate_config=1
Network={
Ssid=" myaccesspoint "
Proto=WPA
Key_mgmt=WPA-PSK
Psk=" youpasswords "
}
Visible, although android system is in default situations, station maintenance process can be automatically switched off while opening focus maintenance process, but, use instruction by above or use configuration file two ways, it is possible to achieve being controlled the unlatching of described station maintenance process by program process voluntarily.
Focus maintenance process, refers in particular to the hostapd process that android system provides.Hostapd is that the finger daemon of user control is for WAP (AP) and authorization server (authenticationservers).Hostapd achieves the AP management of IEEE802.11, IEEE802.1X/WPA/WPA2/EAP authorizes, radius client, EAP server and radius authorization server, latest edition supports linux system (HOSTAP at present, madwifi, mac80211-based drive) and FreeBSD (net80211).Hostapd is designed as a demons (process), running background, carries out the operation of some relevant control mandates.
The difference of Hostapd Yu wpa_supplicant is mainly reflected in wpa_supplicant and supports basic AP operation, but does not include various finer parameter adjustment, such as WPA2-Enterprise (RADIUSserver certification).As can be seen here, two kinds of processes are simply divided the work difference, and it acts on approximation.
In like manner, hostapd allows to be configured it by certain mode, such that it is able to started it voluntarily by application program.An example utilizing its configuration file to realize configuration presented below:
It is the topology example of a relevant configuration file herein, left side serial number line number for reference:
Based on this configuration file, focus can be set up as follows:
Build bridge: sudoapt-getinstallbridge-utils
Set up bridge:
sudobrctladbrbr0
02.sudoifconfigbr0192.168.2.236netmask255.255.255.0
03.sudorouteadddefaultgw192.168.2.254
Connection bridge two ends:
sudobrctladdifbr0eth0
02.sudobrctladdifbr0wlan0
Enable configuration:
sudo./hostapdhostapd.conf
Generally, as without other faults, other intelligent terminal just can scan the SSID of the focus thus set up, and owing to this focus is self-built, does not possesses DHCP service, therefore intelligent terminal needs to coordinate voluntarily static IP and could realize LAN and connect.
Below the station maintenance process be given respectively and the principle of focus maintenance process and the exemplary introduction implemented thereof, those skilled in the art on basis disclosed above, can understand the flexible and changeable implementation of the present invention.Wherein it is desired to it is noted that for the facility realized, improve efficiency of the practice, no matter for hostapd or wpa_supplicant process, all recommend configuration file and its .conf file that is preset in of network configuration information is carried out pre-configured, then restart corresponding maintenance process.
As described in previous step, user both can wish to open hotspot pattern and station mode by single control button simultaneously, it is also possible to is opened by two buttons corresponding with both of which, essentially provides multiple operation change case.These changes corresponding, illustrate further below.
If user interface provides single control button, user triggers its user instruction by this single control button, the most just can first open hostapd process, i.e. focus maintenance process.Owing to the unlatching of hostapd process can cause being automatically switched off wpa_supplicant process, therefore, the program process of the present invention needs with reference to above-mentioned implementation, after focus maintenance process is opened, start this station maintenance process the most voluntarily, the most just can realize two maintenance process and deposit.Otherwise, it is also possible to starting website maintenance process in advance, after it completes to open, then row opens focus maintenance process with reference to above-mentioned example.It is to say, the control instruction caused corresponding to single control button, can be with focus maintenance process and the boot sequence of station maintenance process described in different embodiment flexible arrangement.
And correspondence user interface provides different control buttons, for characterizing the example of different maintenance process of opening an account respectively, then can click on the different order controlling button by user and sequentially open corresponding maintenance process, this measure has no effect on the enforcement of the present invention.
Realize man-machine interaction howsoever, the focusing on both and in succession open of the control of focus maintenance process and station maintenance process, and need the process of the application program alleged by the present invention to be acted on.
In preferred scheme, it is recommended that preferentially allow station maintenance process open prior to focus maintenance process, in the case of guaranteeing that this intelligent terminal can connect outer net, provide access function to other intelligent terminal, some idle works can be exempted, the most energy-conservation.
In theory, after station maintenance process and focus maintenance process being sequentially activated, coexisting of two maintenance process can just be realized, then, because of system may the impact of potential some risks, may result in two maintenance process and one of to be arbitrarily closed, thus still need and strengthened by follow-up means.
Step S13, maintains described focus maintenance process and described station maintenance process to be coexisted formula work.
The formula that coexists work designated herein, refers to that focus maintenance process may be opened in succession with station maintenance process, but may not open by synchronization.As long as both of which is present in internal memory operation, both cycle of operations in internal memory have temporal concurrently so that within a time cycle, intelligent terminal can be access in and can also access other access points, i.e. can be considered coexist formula work.
After focus maintenance process is unlocked, owing to it will close website maintenance process, thus, the program process of the present invention is suitably according to predetermined scheduled duration, and after scheduled duration terminates, then row starts website maintenance process, in order to avoid previous station maintenance process collision, cause startup unsuccessful.In like manner, if first starting website maintenance process, for avoiding it may close focus maintenance process, it is possible to be suitable for this method.
In order to ensure described focus maintenance process and described station maintenance process during user uses normally or relative normally use; whether the program process of the present invention can be closed with any one in two maintenance process of periodic scanning on backstage; when one of them is closed; control pent process the most in the manner previously described to open; so that it is guaranteed that expect according to user, two maintenance process are made to work with can coexisting formula.
Visible, maintain focus maintenance process and station maintenance process to run in internal memory, be to ensure that the reinforcement means of network stabilization.
Step S14, characterizes the object information of the concurrent state that this intelligent terminal is in hotspot pattern and station mode coexists to user interface output.
In the control device completing above-mentioned step S12 or S13, make two maintenance process coexist formula work after, the program process of the present invention just can export some object informations to user interface, to inform the concurrent state that this intelligent terminal of user currently coexists already at hotspot pattern and station mode.Expression-form as described object information, both can be to be shown in informing by system message, can also pop-up show on the table, more excellent mode can be to call default third party's icon, for characterizing the concurrent state that this intelligent terminal is in hotspot pattern and station mode coexists, this third party's icon is shown in the system mode hurdle of user interface so that user is easier to know described object information.
It is to be noted, after described step S12 is run, step S14 can be performed in theory realize icon and show, then step S13 is continuously carried out, thus, it will be appreciated by those skilled in the art that the execution sequence that should not understand each step of the present invention with the character arranging order of the present invention, and should be understood with the substantial principle disclosed in the present invention.
