S307; MEP1 receives the LMR message; This locality of sending statistical value TxFCf, the MEP2 of message according to this locality of the statistical value RxFCl of the local reception message of MEP1 and the MEP1 in the LMR message receives that this locality of the statistical value RxFCf of message, MEP2 sends this locality of statistical value TxFCb and the MIP1 of message, MIP2 and receive the statistical value or the local statistical value that sends message of message, confirms the packet drop between per two nodes among MEP1, MIP1, MIP2 and the MEP2.
For example, can utilize current time (tc) and last each statistical value calculating far-end and the near-end packet drop of (tp) constantly.
For the far-end packet loss:
MEP1 to MEP2 packet loss number does, | TxFCf [tc]-TxFCf [tp] |-| RxFCf [tc]-RxFCf [tp] |;
MEP1 to MIP1 packet loss number does, | TxFCf [tc]-TxFCf [tp] |-| RxFCf_MIP1 [tc]-RxFCf_MIP1 [tp] |;
MEP1 to MIP2 packet loss number does, | TxFCf [tc]-TxFCf [tp] |-| RxFCf_MIP2 [tc]-RxFCf_MIP2 [tp] |.
For the near-end packet loss:
MEP2 to MEP1 direction packet loss number does, | TxFCb [tc]-TxFCb [tp] |-| RxFCl [tc]-RxFCl [tp] |;
MEP2 to MIP2 direction packet loss number does, | TxFCb [tc]-TxFCb [tp] |-| RxFCf_MIP2 [tc]-RxFCf_MIP2 [tp] |;
MEP2 to MIP1 direction packet loss number does, | TxFCb [tc]-TxFCb [tp] |-| RxFCf_MIP1 [tc]-RxFCf_MIP1 [tp] |.

For example, MIP2 searches the TLV corresponding with MIP2 according to sub TLV offset, and the value of TxTimeStampb field among this TLV is revised as the timestamp that MIP2 receives this DMR message, is expressed as TxTimeStampb_MIP2.Then the value of prev TLV offset (pointing to a last TLV) is composed the offset to sub TLV.
S506, MIP1 receives this DMR message, among the TLV of all expansions in this DMR message, searches for the TLV corresponding with MIP1, and record MIP1 sends the timestamp of this DMR message in the TLV corresponding with MIP1, then this DMR message is sent.
For example, MIP1 searches the TLV corresponding with MIP1 according to sub TLV offset, and the value of TxTimeStampb field among this TLV is revised as the timestamp that MIP1 sends this DMR message, is expressed as TxTimeStampb_MIP1.Then the value of prev TLV offset is composed the offset to sub TLV.
S507; MEP1 receives this DMR message; Receive the time RxTimeb of this DMR message and time stamp T xTimeStampf, MEP2 that the MEP1 in this DMR message sends this DMM message according to MEP1 and receive that timestamp RxTimeStampf, the MEP2 of this DMM message send the time stamp T xTimeStampb of this DMR message and timestamp that MIP1, MIP2 receive this DMM message or send the timestamp of this DMM message and send the timestamp of this DMR message or receive the timestamp of this DMR message, confirm the time delay situation between per two nodes among MEP1, MIP1, MIP2 and the MEP2.
Two-way time delay does between MEP1 and MEP2, (RxTimeb-TxTimeStampf)-(TxTimeStampb-RxTimeStampf);
Two-way time delay does between MEP1 and MIP1, (RxTimeb-TxTimeStampf)-(TxTimeStampb_MIP1-RxTimeStampf_MIP1);
