Abstract

The present invention discloses a method and an apparatus for implementing an access to a Machine to Machine (M2M) core network. In the method, a network element receives an access request message carrying equipment identity indication information, wherein the access request message is initiated by terminal equipment; the network element determines that the terminal equipment is M2M equipment according to the equipment identity indication information; and the network element selects a corresponding M2M core network for the terminal equipment to implement the access of the terminal equipment. According to the technical solution provided by the present invention, the existing network can meet the M2M service requirement while providing services for existing Human to Human (H2H) equipment, without any need of enhancement and mass expansion.

Claims

selecting, by the radio access network, a corresponding first core network address for the terminal equipment according to information of a preconfigured corresponding relationship between a terminal equipment identity and the M2M core network; and

initiating, by an enhanced radio access network, an access request to the corresponding M2M core network according to the first core network address.

5. The method according to claim 2, wherein the step of selecting, by the virtual gateway, the corresponding M2M core network for the terminal equipment to implement the access of the terminal equipment comprises:

selecting, by the virtual gateway, a corresponding second core network address for the terminal equipment according to information of a preconfigured corresponding relationship between a terminal equipment identity and the M2M core network;

sending, by the virtual gateway, the second core network address to the radio access network; and

initiating, by the radio access network, an access request to the corresponding M2M core network according to the second core network address.

6. The method according to claim 5, wherein before the step of selecting, by the virtual gateway, the corresponding second core network address for the terminal equipment, the method further comprises:

after the radio access network receives the access request message from the terminal equipment, requesting, by the radio access network, the second core network address from the virtual gateway.

7. The method according to claim 2, wherein the step of selecting, by the virtual gateway, the corresponding M2M core network for the terminal equipment to implement the access of the terminal equipment comprises:
