As shown in Figure 3, the flow chart that the wired lan user that visits its resource and WLAN user is carried out authentication for wired WAN system and wireless WAN system, in the step 30, wired lan user and WLAN user visit wired WAN system or wireless WAN system by mobile bridge, mobile bridge judges whether to provide wired WAN resource in the step 31, if can provide wired WAN system resource for wired lan user and WLAN user capture, then execution in step 32, wherein mobile bridge adopts Internet Control Message Protocol (ICMP, whether PING (Packet InterNetGroper) order that is in application layer InternetControl Message Protocol) detects has the equipment that wired WAN resource can be provided to arrive, if detect wired WAN resource apparatus that can arrive, then mobile bridge is thought can provide wired WAN system resource to WLAN user or wired lan user capture; If do not detect wired WAN resource apparatus that can arrive, then mobile bridge is thought can not provide wired WAN system resource to WLAN user or wired lan user capture.In the step 32, wired WAN authentication modes such as authentication mode of authentication mode, IEEE802.1X authentication mode or PPPoE agreement that employing Radius Client and Web Portal combine carry out authentication to wired lan user and WLAN user; Can not provide wired WAN system resource if in step 31, judge, then move bridge and judged whether that wireless WAN system resource can be for visit in step 33, if forward in the step 34, use the authentication mode of wireless WAN that user identity is authenticated, wherein the authentication mode of wireless WAN comprises that wireless WAN is to being linked into the entrained subscriber identification module of user terminal of self network system, as SIM card (being used for the GSM network system) or UIM card (being used for the cdma network system), or some serial number data of being fired on the chip in the terminal itself are carried out authentication, guarantee to have only legal wired lan user or the wireless WAN system resource of WLAN user capture.It is the above-mentioned SIM card module of in step 35, utilizing in the mobile bridge, allow mobile bridge authenticate in the wireless WAN system as a mobile subscriber in the wireless WAN system, then in step 36, in Internet resource by wireless WAN system dereference, by traditional authentication mode each WLAN user and the wired lan user who visits the Internet resource carried out authentication, wherein said traditional authentication mode is identical with the described authentication mode of step 32; If judging in step 33 does not have the wireless WAN system resource can be for visit, then forwarding step 37 notice WLAN user and wired lan user this moment to can not the accesses network resource, the not responsible handling user identity authentication of mobile bridge.
After the user finished authentication, just can the accesses network data resource.If just the packet in the Wireless LAN system is transmitted, then only transmit by 13 pairs of packets of wireless interface module; Packet between Wireless LAN system and the wired lan system is finished forwarding mechanism jointly by spanning-tree bridge STP Bridge module and wireless interface module; Packet was finished the judgement of data source and destination interface earlier when Wireless LAN system and wired lan system visited wired WAN system resource by spanning-tree bridge STP Bridge module, finish the conversion of packet networks address by data being sent to network address translation NAT module then, send in the wired WAN system rightabout packet transfer process contrary; The forwarding of packet also was through finished the judgement of data source and destination interface earlier by spanning-tree bridge STP Bridge module when Wireless LAN system and wired lan system visited wireless WAN system resource, by it data are sent to network address translation NAT module then and finish the conversion of packet networks address, secondly also to carry out IP packing data processing procedure, to guarantee the conversion between the network different agreement, this IP bag processing procedure can realize in mobile bridge by software, can realize in wireless WAN network interface card module that also its implementation procedure also is different according to its processing procedure of difference of wireless WAN system type.
Need on mobile bridge, realize the user data traffic controlled function in the inter-network data bag repeating process, customer flow control, promptly after user identity is by authentication and authorization, according to the data rate needs that each network allows the user's data flow is gathered, limited, charging information is provided simultaneously.User data traffic control both can realize on two layers of spanning-tree bridge forwarding mechanism of packet, also can realize in three layers of routing forwarding mechanism, and basic principle is exactly that the data of Control Network interface are sent out speed outward.Because the user data traffic that needs to control in mobile bridge is to insert the data traffic of wireless WAN system and wired WAN system, so we can control user data traffic on the basis of three-layer network address transition NAT module.
User data traffic control realizes by queue mechanism, for mobile bridge, we can regard the wave point of LAN ethernet controller interface and wireless interface module as downlink port, and the wave point of WAN ethernet controller interface and wireless WAN network interface card module is regarded uplink port as.
User data traffic control will be controlled the user sends out data by equipment interface speed exactly, control user's upstream data rate if desired, just need the control user to send and by the data transmission rate of device forwards to uplink port, and control user's downstream rate if desired, then need control to mail to the user's data transmission rate to downlink port by device forwards.Since we can only the Control Network interface transmission rate, we can only be inserted into flow control function two stages in the flow process: promptly before the packet queuing or packet control after lining up.Consider if after the packet queuing, carry out flow control again, need formation to have enough big capacity just to be unlikely to cause overflowing of formation easily, and need the extra processing time, therefore adopt before the packet queuing and just carry out flow control.
No matter packet is to mail to downlink port or mail to uplink port from downlink port from uplink port, and packet will carry out data traffic control, the forwarding speed of coming control data before turnover network address translation NAT module is carried out the packet queuing.
Shown in Figure 4, network address translation NAT module at first receives packet from the upstream or downstream network port in step 100, then in step 200, network address translation NAT module can be carried out necessary filtration according to the packet that the packet header sign butt joint of packet is received, keep the packet that needs forwarding, abandon illegal packet; In step 300 packet being transmitted from up link or down link then, before joining the packet queuing of waiting to send out, at first is seven relevant parameters of each user definition in step 400, comprising:
The MAC Address macAddr of client;
The upstream rate upRate of client;
The downstream rate downRate of client;
The current period (1 second), interior user uplink sent data counts upCount;
The descending transmission data counts of (1 second) interior user of current period downCount;
User uplink sends data amount and counts upTotal;
The descending transmission data amount of user is counted downTotal;
The method that increases flow control is, packet needs to check before queuing on the user has sent in the current period (1 second)/the downlink data amount whether greater than on the user/data volume of downstream rate defined, if not, just forward in the step 600 this packet is joined in the outgoing queue, in step 700, packet is sent to uplink port or downlink port then; Otherwise forward step 800 to this packet is done discard processing.Wherein the numerical value of upCount/downCount constantly upgrades along with data transmission procedure, it is clearly once zero that the beginning of promptly 1 second each cycle period is set, can guarantee that like this data that at every turn are checked through are the data that refresh always, make user data traffic precisely controlled.
Can be between the mobile bridge by the wireless connections mode of wireless distribution system WDS, when the WLAN user being entered into to visit Wireless LAN system resource regional in the area that can visit the Wireless LAN system resource, mobile bridge can be automatically authenticates to wireless WAN system as the mobile subscriber in the wireless WAN system, the WLAN user is roamed in the wireless WAN system by mobile bridge, carry out visit wireless WAN system resource; Entering into by the area that can not visit the Wireless LAN system resource can visit Wireless LAN system resource regional the time simultaneously, mobile bridge also can switch to Wireless LAN system to the WLAN user as access point AP automatically, make its visit Wireless LAN system resource, switch thereby finish the roaming of mobile bridge between Wireless LAN system and wireless WAN system.
In WLAN user or the wired WAN system resource of wired lan user capture, or when carrying out data communication by the wireless WAN dereference Internet of system resource, can in WLAN user or wired lan user's terminal, increase the speech coding module, be implemented in when carrying out data communication, can carry out based on the voice communication of packet switching or based on Circuit-switched voice communication, satisfy the user to the webpage that surfs the web, carry out the demand of voice call simultaneously.
