Detailed Description
In order to solve the security problem of transmitting photos by a camera terminal, in the embodiment of the invention, a wireless network is divided into more than one Virtual Local Area Network (VLAN), in the access process of the camera terminal, the wireless network side authenticates the camera terminal by using the MAC address of the camera terminal, if the camera terminal passes the authentication, the MAC address is set as a legal user, and the MAC address is registered to the VLAN to which the MAC address belongs. Therefore, after the camera terminal accesses the wireless network, the shot picture data can be transmitted to the picture receiving server in the belonging VLAN. And if the authentication is not passed, the access of the camera terminal is refused. Here, the camera terminal refers to a digital camera having a WIFI transmission module.
The wireless network authenticating the camera terminal by using the MAC address of the camera terminal may be implemented as follows: the wireless network controller judges whether the MAC address is a registered legal address or not, and if not, the MAC address is sent to an authentication server; and the authentication server determines whether the MAC address is a legal address, if so, the authentication is passed, and otherwise, the authentication is failed.
The setting of the MAC address as a valid user and registering the MAC address to the VLAN may be: the wireless network controller determines the VLAN to which the MAC address belongs and feeds the VLAN back to the wireless network controller; the wireless network controller sets the MAC address as a legal user and registers the MAC of the terminal in the VLAN to which the terminal belongs.
The camera terminal may be a camera, or a video camera. The camera terminal transmits the shot photos to the picture receiving server after shooting one photo at a time, or transmits the shot photos to the picture receiving server in a centralized manner after shooting a certain number of photos.
Referring to fig. 1, a specific implementation process of the embodiment of the present invention is as follows:
step 101: the camera terminal sends an access request to the wireless network controller, wherein the access request contains the MAC address of the camera terminal.
Step 102: the wireless network controller judges whether the MAC address is a legal address registered in the local configuration, if not, the MAC address is sent to an authentication server, step 103 is executed, otherwise, the authentication is passed, the camera terminal is notified that the access is successful, and step 105 is executed.
Step 103: the authentication server inquires whether the MAC address is a legal address in a local database, if so, the authentication is passed, the VLAN to which the MAC address belongs is determined, and then an authentication result is fed back to the wireless network controller, otherwise, the authentication is failed.
The authentication server stores the MAC address information included in the VLAN, namely, the corresponding relation between the VLAN Identification (ID) and more than one MAC address is stored, and the VLAN to which the MAC address belongs can be determined according to the information.
Step 104: if the result fed back by the authentication server is that the authentication is passed, the wireless network controller adds the MAC address into local configuration as a legal user, registers the MAC of the terminal into the VLAN to which the terminal belongs, and sends an access response to the camera terminal.
Step 105: and after receiving the successful access response, the camera terminal is connected to the picture receiving server of the VLAN to which the camera terminal belongs, and transmits the shot picture data to the picture receiving server.
Referring to fig. 2, a system for implementing an instant messaging service according to an embodiment of the present invention at least includes: wireless network, camera terminal and picture receiving server.

and the authentication server is used for authenticating the MAC address and notifying the wireless network controller of the VLAN to which the MAC address belongs after the MAC address passes the authentication.
VLAN partitioning may be implemented by a radio network controller. The multiple VLANs of china mobile are realized under the same Service Set Identifier (SSID), that is, the SSIDs of Wireless Local Area Networks (WLANs) selected by all terminals of the VLANs during access are the same. Therefore, after a plurality of VLANs are divided, when data packets from different terminals flow through the wireless network controller, the wireless network controller authenticates information such as destination addresses of the data packets, controls all the data packets to be transmitted only in the range of the VLAN to which the data packets belong, and ensures the safety of the data packets.
When the camera terminal accesses the network, the wireless network controller can obtain the MAC address of the equipment, send the MAC address to the authentication server for authentication, verify whether the user is a legal authorized user and the VLAN to which the user belongs, and feed back the authentication result to the wireless network controller. If the user is a legal authorized user, the wireless network controller registers the user to the VLAN to which the user belongs, allocates an IP address under the VLAN for the user and allows access; otherwise, the access of the terminal is refused.
As shown in fig. 3, the radio network controller includes: a judging unit, a setting unit and a registering unit. Wherein,
a judging unit, configured to judge whether an access request from the camera terminal is legal, and if not, send the MAC address to the authentication server;
