Embodiment 1
[0037] figure 2 It is a schematic diagram of the topological structure of the wireless sensor network sensor node accessing the mobile communication network in Embodiment 1 of the present invention, image 3 The flow chart of the access authentication method for the provided sensor node includes:
[0038] Step S301, the sensor node sends an access request to the sink node SINK node, and the access request carries the ID information of the sensor node.
[0039] Step S302, after receiving the access request, the aggregation node forwards the access request to the network side of the mobile communication network, so that the network side can perform subsequent access authentication processing.
[0040] Specifically, the access request can be sent to the visitor location register VLR. If the VLR determines that the sensor node is a user in the local domain according to the ID information carried in the access request, it can directly perform subsequent access authentication proc...
Embodiment 2
[0084] Based on the same inventive concept, according to the sensor node access authentication method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 2 of the present invention also provides a sensor node, and its structural diagram is as follows Figure 6 shown, including:
[0085] The sending unit 601 is configured to send an access request to the convergence node, and send the access request to the network side of the mobile communication network through the convergence node; and send the generated access authentication response to the network side through the convergence node, for the network The side performs access authentication on the sensor node;
[0086] The receiving unit 602 is configured to receive the access authentication message sent by the network side forwarded by the convergence node;
[0087] The authentication unit 603 is configured to generate an access authentication response based on the access authenti...
Embodiment 3
[0094] Based on the same inventive concept, according to the sensor node access authentication method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a convergence node, and its structural diagram is as follows Figure 7 shown, including:
[0095] The first interaction unit 701 is configured to receive an access request sent by the sensor node; forward the received access authentication message sent by the mobile communication network side to the sensor node; and receive an access authentication response sent by the sensor node;
[0096] The second interaction unit 702 is configured to forward the access request to the network side; receive the access authentication message sent by the network side; and forward the access authentication response to the network side.
