1. a kind of communication means, which is characterized in that including:

  • Obtain transmission data to be sent;

    Transmission data coding is generated into data packet on code field, the code field is can be straight in the data packetConnect the field for monitoring content;

    Send the data packet;

    Wherein, by multiple data packet groups at data packet group complete the transmission of the primary transmission data, it is described by instituteState transmission data coding includes the step of generating data packet on the code field of data packet:

    The data field for being used for identified control field and for loading the transmission data is generated according to the transmission data;

    The control field and the data field sequential encoding are generated more on the code field of multiple data packetsA data packet;

    Wherein, the control field includes multiple identification fields;

    Each identification field includes four identification bytes, the knowledgeMalapropism section includes the message code for identified cognizance code and for loading information;

    Each the identification byte is high by 4Position is cognizance code, and low 4 are message code;

    The first two described information code loads respectively wants the 4 high of transmission data lengthWith low 4;

    Latter two described information code loads respectively will send high 4 and low 4 of service set cyclic redundancy check codePosition;

    In transmission process, the service set cycle that receiving terminal first obtains Target Wireless access points from identification field is superfluousThen remaining check code scans obtained service set cyclic redundancy check code and is compared, again and in advance if it find that phaseWith value, then receiving terminal does not have to receive service set information again in next receive process.
