Embodiment
Networking flexibility when improving the wireless device shared bandwidth, ease for use, and network utilization the invention provides a kind of method and wireless device of wireless device shared bandwidth.Below in conjunction with accompanying drawing, further describe in the mode of specific embodiment.
Scene as shown in Figure 1, wireless device A is the WIFI equipment of no Internet access capability, wireless device B is the WIFI equipment that the Internet access capability is arranged, and wireless device A and wireless device B set up shared bandwidth, and wireless device A inserts Internet by wireless device B.Wherein, wireless device A and wireless device B are the wireless device in the embodiment of the invention, and it comprises with lower module (if do not add explanation, being example with wireless device A promptly in the present embodiment):
Link control module: the type field of link control module on data link layer increases the private network type, and all control messages are finished by network layer.When device start, link control module is initiated connection request to other wireless devices, consults shared bandwidth information with other wireless devices, the management connection status.In the process of equipment operation, periodically update network state.
Load balancing module: when existence is connected with miscellaneous equipment, judge current network state and utilization rate, dynamically adjust the distribution of bandwidth for application program, judge promptly whether required bandwidth exceeds the bandwidth threshold values of this equipment, if then being judged to be needs to transmit, and sends forward signal; Otherwise being judged to be does not need to transmit.
Data forwarding module: after the data forwarding module of wireless device A is received the forward signal that load balancing module sends, packet is forwarded to also chosen other equipment (wireless device B) that connect, the data forwarding module of wireless device B is by NAT (Network Address Translation) and NAPT (Network Address Port Translation), with the address translation of wireless device A is the local port of wireless device B, is equivalent to wireless device A is mapped as wireless device B local network application program.Afterwards, wireless device B can be sent to network with application's data bag on this equipment (being that wireless device A transmits the packet of coming) by this port.
As shown in Figure 2, the handling process of link control module is as follows:
Step 101: initiate connection request.In the communication process of wireless device, link control module periodically sends broadcast, adds new connection.And the existing state that connects of renewal.Behind the sign off, wireless device sends to connect to miscellaneous equipment and disconnects message.
Whether step 102: checking has new available connection.If any execution in step 103 then, otherwise finish.
Step 103: to available wireless device request available bandwidth ability, if available bandwidth is arranged, then execution in step 104, otherwise finish.
Step 104: consult cipher mode, if support the other side's cipher mode, execution in step 105, otherwise finish.
Step 105: upgrade current connection status, and be sent to load balancing module.
As shown in Figure 3, the handling process of load balancing module is as follows:
Step 201: slave driver obtains packet.
Step 202: estimate the bandwidth that needs are newly-increased according to current bandwidth occupancy situation.
Step 203: if the bandwidth that needs does not exceed the bandwidth threshold values of this equipment, then use this device bandwidth, otherwise execution in step 204.Be in the communication process, application's data judges through load balancing module that earlier in the time of can not satisfying the demands as if the current Internet access bandwidth, load balancing module is according to current available shared bandwidth state, whether decision needs to transmit, and the destination address of transmitting.Afterwards by data forwarding module with data forwarding.In the load balancing module, the local connection enjoyed limit priority, secondly be AP with Client between be connected (only existing on the AP equipment), shared bandwidth priority is minimum.When bandwidth demand changes, load balancing module will be determined network bandwidth allocation according to priority, and upgrade current network state by link control module.
Step 204: check and share the state that connects, if on other wireless device available bandwidth is arranged, then execution in step 205.
Step 205: packet is forwarded to other wireless devices.
Step 206: judge that whether transmission is successful, if send successfully, then finishes this transmission flow; If send failure, then upgrade connection status to the link control module request.The reason that causes sending failure may be that method, apparatus has been disconnected or do not have available bandwidth etc. temporarily.
As shown in Figure 4, the flow process that connection is set up between wireless device is as follows:
Step 301:, initiate connection request by wireless device A broadcasting.
Step 302: after wireless device B received the request of wireless device A, whether decision allowed to connect.Then send response message if allow to wireless device A.
Step 303: the available bandwidth of wireless device A request wireless device B, and the available bandwidth ability that wireless device A is current sends to wireless device B.
Step 304: the message that wireless device B will comprise the available bandwidth data sends to wireless device A.
Step 305: wireless device A sends to wireless device B with available cipher mode.
Step 306: the cipher mode that wireless device B selects both sides to support, respond and give wireless device A.
Step 307: wireless device A is connected by the data forwarding module of data forwarding module with wireless device B.
As shown in Figure 5, introduce a networking embodiment, comprise following several equipment in the network:
AP (Access Point, wireless access node): can directly insert Internet, support the bandwidth sharing functionality.
ClientA: promptly traditional Wifi client.Cannot directly insert Internet, not support the bandwidth sharing functionality.
ClientB: the WiFi equipment of supporting the bandwidth sharing functionality.
AP1 and AP2 insert Internet by modes such as xDSL or Ethernets, support the bandwidth sharing functionality.ClientB1 can be equipment such as mobile phone or data card, and itself can insert Internet with the 2G/3G communication technology, supports the bandwidth sharing functionality.ClientB2 does not have the ability of direct access Internet, supports the bandwidth sharing functionality.ClientA1, ClientA2, ClientA3 are the WiFi equipment of not supporting bandwidth sharing, still connect with traditional WiFi and insert AP1 and AP2.In this network, AP1, AP2, ClientB1, ClientB2 sets up network by the bandwidth sharing function, share I nternet access bandwidth.
To sum up, the present invention connects by the automatic dynamic between each wireless device, and shared bandwidth has improved the bandwidth upper limit and network utilization.Whole process does not need the user to be provided with, and is simple and easy to use.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
