embodiment 1
[0124]FIG. 12 shows a flowchart of an MTC UE performing an attachment procedure to an M2M core network through an existing radio access network by adopting Mode 1 in a GPRS network according to the present invention. As shown in FIG. 12, in the GPRS network, an M2M core network is overlapped in the existing core network to share the existing radio access network. The radio access network can judge whether the access equipment is H2H equipment or M2M equipment according to the terminal equipment type or the access capability, and then select a corresponding core network address to accomplish the subsequent access processes. The access process mainly comprises the following steps (Step 1202 to Step 1212).
[0125]Step 1202: the MTC UE initiates an attachment request message (for example, access request message) to the radio access network, and adds an equipment type indication parameter (that is, equipment type indication information) in the attachment request message through parameter e...
embodiment 2
[0135]FIG. 13 shows a flowchart of an MTC UE performing an attachment procedure to an M2M core network through an existing radio access network by adopting Mode 1 in an EPS network according to the present invention. As shown in FIG. 13, in the EPS network, an M2M core network is overlapped in the existing core network to share the existing radio access network. The radio access network can judge whether the access equipment is H2H equipment or M2M equipment according to the terminal equipment type and / or the access capability, and then select a corresponding core network address to accomplish the subsequent access processes. The above process mainly comprises the following steps (Step 1302 to Step 1312).
[0136]Step 1302: in order to access the EPS network, the UE initiates a network attachment request message to an eNodeB, wherein the request message carries equipment type indication information (equipment type indication parameters) such as IMSI, equipment type indication, network ...
embodiment 3
[0154]FIG. 14 shows a flowchart of an MTC UE performing an attachment procedure to an M2M core network through an existing radio access network by adopting Mode 2 in a GPRS network according to the present invention. As shown in FIG. 14, in the GPRS network, an M2M core network is overlapped in the existing core network to share the existing radio access network. The radio access network inquires the access address of the core network from the V-GW; the V-GW can judge whether the equipment is H2H equipment or M2M equipment according to relevant information carried by the terminal, such as IMSI, MSISDN, APN, equipment type, access capability and other indications, and then select a corresponding core network address (that is, the second core network address) to accomplish the subsequent access processes. The above process mainly comprises the following steps (Step 1402 to Step 1412).
[0155]Step 1402: the MTC UE initiates an attachment request message (access request message) to the ra...
