Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.But embodiments of the present invention are not limited thereto.
The principle of each embodiment of the present invention is: had WIFI hot spot based on present most of smart mobile phone and set up on the basis of function, by having the mobile phone deploy dedicated program of WIFI hot spot function, it is made to possess the ability bearing emergency network covering among a small circle.Namely a certain operator 2G/3G signal fail to cover very well among a small circle in, one or more mobile phone with WIFI hot spot capacity-building provides emergency parachute covering power by dedicated program to the other-end in certain distance.
By WIFI passage between " blind spot mobile phone " and " focus mobile phone ", adopt SIP(Session Initiation Protocol, session initiation protocol) agreement is as Signalling exchange, by " blind spot mobile phone " active call " focus mobile phone ", this is called through GSM network and is sent in " target mobile phones " by " focus mobile phone " again, thus sets up the speech channel between " blind spot mobile phone " and " target mobile phones ".On the other hand, the function that " if blind spot mobile phone " is provided with " when cannot connect, focus mobile phone is transferred in calling ", so when " target mobile phones " is by GSM network calling " blind spot mobile phone ", will transfer to " focus mobile phone ", after " focus mobile phone " receives this GSM call signal, this is called through WIFI and is sent on " blind spot mobile phone " in the mode of SIP signaling by " focus mobile phone " again, thus sets up the speech channel between " target mobile phones " and " blind spot mobile phone ".
As shown in Figure 1, be the emergency communication method principle flow chart that the embodiment of the present invention 1 provides, specific as follows:
Step 10, blind spot mobile phone and focus mobile phone establish a communications link.
The system that the embodiment of the present invention 1 is formed based on the blind spot mobile phone of as shown in Figure 2, focus mobile phone and target mobile phones, wherein, " blind spot mobile phone " refers to the mobile phone of the support WIFI function being positioned at signal blind spot region; " focus mobile phone " refers to the mobile phone that have support WIFI in the region of quorum sensing inhibitor and GSM function adjacent with signal blind spot region, need be set to WIFI hot spot; Need the SGW software disposing special exploitation simultaneously; " target mobile phones " refers to the mobile terminal device needing the support gsm protocol communicated with " blind spot mobile phone ".
" blind spot mobile phone " installs general SIP client software, is connected to " focus mobile phone " by WIFI." focus mobile phone " enables WIFI hot spot function, and enables dedicated gateway program." blind spot mobile phone " is successfully registered to the dedicated gateway program of " focus mobile phone ", by SIP client, and calling " target mobile phones ".After " focus mobile phone " dedicated gateway process accepts to SIP:INVITE call request, this calling is maintained.
Step 20, focus mobile phone obtains target mobile phones information, and is established a communications link by communication network and target mobile phones.
" focus mobile phone " dedicated gateway program goes out " target mobile phones " number according to SIP signaling resolution, and dedicated gateway program uses GSM network calling " target mobile phones " number, and connects.
Step 30, described target mobile phones and blind spot mobile phone are set up bridge joint by focus mobile phone, set up the communication connection between blind spot mobile phone and target mobile phones.
After connecting " target mobile phones ", the SIP calling previously kept of going bail for, and bridge joint is carried out to SIP speech channel and GSM speech channel, complete mixing operation; If access failure, then report voice and hang up SIP speech channel.
Since then, " blind spot mobile phone " and " target mobile phones " complete speech channel and overlap, and start call.
Before this, in fact also need blind spot mobile phone to the accreditation process of focus mobile phone, specifically comprise:

" blind spot mobile phone " is connected to " focus mobile phone " by WIFI;
" blind spot mobile phone " is successfully registered to the dedicated gateway program of " focus mobile phone ";
" target mobile phones " is by GSM network calling " blind spot mobile phone ";
This calling is transferred to " focus mobile phone " by GSM network;
After " focus mobile phone " dedicated gateway process accepts to this GSM call request, this calling is maintained;
" focus mobile phone " dedicated gateway program goes out " blind spot mobile phone " number according to GSM signaling resolution;
Focus mobile phone dedicated gateway program searches the information of register account number as " blind spot mobile phone " number from registering cache information, if found, then initiates SIP:INVITE operation to blind spot mobile phone;
After connecting " blind spot mobile phone ", the GSM calling previously kept of going bail for, and bridge joint is carried out to GSM speech channel and SIP speech channel, complete mixing operation; If access failure, then report voice and hang up GSM speech channel;
Since then, " target mobile phones " and " blind spot mobile phone " complete speech channel and overlap, and start call.
