Claim:
1. A method for Machine Type Communication (MTC) in Long Term Evolution Advanced (LTE-A), comprising: dividing pieces of MTC User Equipment (UE) into at least one cluster unit, each cluster unit comprising one piece of second UE serving as a cluster head and at least one, pieces of first UE serving as cluster members, wherein the number of the pieces of the first UE in the cluster unit is larger than the number of the pieces of the second UE in the cluster unit; the first UE sends data information to the second UE through a Physical Uplink Shared Channel (PUSCH); after receiving the data information the second UE forwards the data information to an Evolved Node B (eNB); the eNB sends Data Transmission Grant (DTG) information to the first UE after receiving the data information to complete data information transmission; before the first UE sends the data information to the second UE through the PUSCH, the method further comprising: forwarding to the eNB, by the second UE, Radio Resource Control (RRC) connection request information sent by the first UE to request for establishment of a network connection, wherein the step of forwarding to the eNB, by the second UE, Radio Resource Control (RRC) connection request information sent by the first UE to request for establishment of a network connection comprises: when a plurality of pieces of the first UE in the cluster unit initiate the RRC connection request to the second UE in the cluster unit, the second UE in the cluster unit selects at least one RRC connection request according to delays of the RRC connection requests and forwards the selected at least one RRC connection request to the eNB; sending, by the eNB, RRC connection establishment information to the first UE; and forwarding, by the first UE, RRC connection establishment completion information to the eNB through the second UE to complete the establishment of the network connection.
