A kind of method that the present embodiment provides mobile terminal to communicate by letter with information safety devices, as shown in Figure 1, the method comprises:
Step S101, mobile terminal adopts the mutually different downlink coding mode of M kind to form M the detection packet after coding to detecting data packet coding, the label information that comprises the downlink coding mode that adopted separately in detection packet after each coding, wherein, M is positive integer.
Concrete, so-called up coded system and downlink coding mode are all for mobile terminal.When information safety devices sends data to mobile terminal, information safety devices is up coded system to data the adopted coded system of encoding, when mobile terminal sends data to information safety devices, mobile terminal is that downlink coding mode is to data the adopted coded system of encoding.Preferably, up coded system and downlink coding mode are FSK coded system.In FSK coded system, adopt the sine wave that S1 sampled point acquisition cycle is T1 to carry out presentation logic 1, adopt the sine wave that S2 sampled point acquisition cycle is T2 to carry out presentation logic 0, wherein, and S1 ≠ S2, T1 ≠ T2, S1 and S2 are positive integer.For example, when sample frequency is 44.1KHz, in FSK-4-8 coded system, after 4 sampled points of sampling are sampled to data-signal, can obtain the sine wave that frequency is 44.1/4=11.025KHz, the cycle T 1 of this waveform is 1/11.025KHz, and this cycle T 1 is used for presentation logic 0 for the sine wave of 1/11.025KHz; After adopting 8 sampled points to sample to data-signal, can obtain the sine wave that frequency is 44.1/8=5.5125KHz, the cycle T 2 of this waveform is 1/5.5125KHz, and this cycle T 2 is used for presentation logic 1 for the sine wave of 1/5.5125KHz.Concrete compound mode also has many kinds, at this, no longer goes to live in the household of one's in-laws on getting married and chats.Adopt FSK coded system to encode, utilize the signal of frequency difference to carry out transmission of information, have that code rate is high, the advantage such as simple of decoding.
Concrete, the mutually different downlink coding mode of M kind can be whole downlink coding modes that mobile terminal is supported, can be also that mobile terminal is selected several downlink coding modes from the downlink coding mode of supporting.
As one of inventive point of the present invention, the label information that mobile terminal has comprised the downlink coding mode adopting in detecting packet, can be so that information safety devices be when receiving detection packet, get the label information of adopted downlink coding mode, thereby which kind of coded system the detection packet that information safety devices can be learnt can receive the decode is, and can be by the label information of downlink coding mode be included in response data packet, facilitate mobile terminal awareness information safety means which kind of coded system of can decoding, in communication, mobile terminal can be taked this downlink coding mode to encode and send data, save information interaction cost.Concrete, the label information of up coded system and the label information of downlink coding mode can be two cover mark modes, should not cause confusion.For example, the label information of up coded system can be " 1,2,3 ... ", and the label information of downlink coding mode can be " A, B, C ... ".
Exemplarily, take M=3 as example, the mutually different downlink coding mode of M kind can be downlink coding mode 1, downlink coding mode 2 and downlink coding mode 3, correspondingly, and for representing that the label information of the mutually different downlink coding mode of this M kind can be " 1,2,3 ".
Step S101 specifically can realize in the following way:
Mobile terminal adopts 1 pair of downlink coding mode to comprise the packet that the detection packet of " 1 " (label information of this downlink coding mode 1) is encoded after the 1st coding of formation, and the packet after the 1st coding comprises " 1 ";
Mobile terminal adopts 2 pairs of downlink coding modes to comprise the packet that the detection packet of " 2 " (label information of this downlink coding mode 2) is encoded after the 2nd coding of formation, and the packet after the 2nd coding comprises " 2 ";
Mobile terminal adopts 3 pairs of downlink coding modes to comprise the packet that the detection packet of " 3 " (label information of this downlink coding mode 3) is encoded after the 3rd coding of formation, and the packet after the 3rd coding comprises " 3 ".
In addition, mobile terminal and information safety devices can be appointed the corresponding relation of the label information of coded system in advance, can, according to the corresponded manner of the label information of arranging in industry, can also be also other corresponded manners that can realize.
Step S102, mobile terminal sends M the detection packet after coding to information safety devices.
Concrete, mobile terminal can be by audio interface by the detection Packet Generation after coding to information safety devices.Certainly, in the situation that intercommunication is permitted, mobile terminal also can be by other interfaces by the detection Packet Generation after coding to information safety devices, or send by the mode of wireless transmission.

(1) response data packet of mobile terminal after to the Y receiving coding decoded and obtained Y response data packet.; due to reasons such as packet losses; although information safety devices has sent the detection packet after Y coding; but mobile terminal has received only the detection packet after Y coding; and in mobile terminal, there be this Y decoding process of detection packet after coding; can all decode to the detection packet after the Y receiving coding, therefore obtain Y and detect packet.
(2) mobile terminal receives Y+j the response data packet after coding; Successively the response data packet after Y+j coding is decoded, obtain Y response data packet, wherein, j is positive integer, and Y+j≤Y.That is, information safety devices has sent Y the detection packet after coding, and mobile terminal receives Y+j the detection packet after encoding, and whether depends on the problem of packet loss, Y+j≤Y.Mobile terminal is decoded to the detection packet after Y+j coding successively, but owing to only there being the decoding process of Y the detection packet after coding in mobile terminal, therefore only can decode to the detection packet after the Y receiving coding, and cannot decode for the detection packet after other j coding, therefore also can only obtain Y and detect packet.
Step S107, mobile terminal, according to the label information of the up coded system of Y kind and the label information of X kind downlink coding mode that get, is determined the up coded system of Y kind and X kind downlink coding mode.
