1. one kind is used to utilize and carries out first and second communication protocols and carry out communication means based on the communication of data cell, wherein above-mentioned first agreement (L1) provide the data cell that is used for controlling above-mentioned second agreement (L2_ARQ) by a physical connection transmission rule and provide at least two different reliability steps for the data unit transmission of above-mentioned second agreement (L2_ARQ), and above-mentioned second agreement (L2_ARQ) provides and is used for the 3rd agreement (L2_ frame;

  • L3) data unit segmentation becomes the rule of data cell of above-mentioned second agreement (L2_ARQ) and the rule of re-transmission that is used for the data cell of above-mentioned second agreement (L2_ARQ),The step that it comprises is;

    The data cell of sign (S1) those second agreements (L2_ARQ), these data cells belong to data structure (the L2_ frame PDU of a data cell that contains this second agreement (L2_ARQ) that is defined;

    L3 PDU;

    L4 PDU;

    SW),To belong to the above-mentioned data structure that is defined (L2_ frame PDU according to the predetermined classification rule;

    L3 PDU;

    L4 PDU;

    The data cell of second agreement (L2_ARQ) SW) is categorized into (S2) at least two different classes, andAbility (the S3 that provides transmission that is divided into inhomogeneous data cell and/or re-transmission for above-mentioned second agreement (L2_ARQ) that different reliability steps is set, S4, S5), these are divided into inhomogeneous data cell and belong to above-mentioned data structure (L2_ frame PDU;

    L3 PDU;

    L4PDU;

    SW).
