Description
Technical field
The invention belongs to data communication field, particularly relate to a kind of method, system and WAP (wireless access point) realizing terminal roaming in wireless network
Background technology
Roaming refers to that terminal is when being connected in a WAP (wireless access point), keeps IP constant, switches the behavior being connected to another access point.Under normal circumstances, terminal is when roaming into another WAP (wireless access point) from a WAP (wireless access point), terminal can send ARP (AddressResolutionProtocol, address resolution protocol) message, and this ARP message outwards can be sent by the WAP (wireless access point) after switching.When connecting the switching equipment of WAP (wireless access point) and receiving this ARP message, can scheduler transmit described in outbound port corresponding to the MAC Address of terminal.Subsequent exchange equipment is when forwarding target MAC (Media Access Control) address is the message of terminal MAC address, by transmitting of terminal MAC address and corresponding outbound port, message can be mail to the port be connected with the new WAP (wireless access point) accessed after terminal roaming, instead of the port be connected with WAP (wireless access point) before roaming.
But in practice, part terminal can not send ARP message when connecting and switching, so subsequent exchange equipment can issue the message of terminal by the latter linked WAP (wireless access point) of switching, actual being but dealt into switches the front WAP (wireless access point) connected, service disconnection when causing roaming.
Be: in the patent application of CN104427567A that AP2 (after roaming access device) meeting proxy terminal transmission ARP message or terminal switch message are to terminal attaching router at publication number.Solve because terminal does not send ARP message and causes terminal attaching router can not upgrade the problem of the mapping relations of terminal MAC address and outbound port.In the invention, the IP address of terminal, when initial access process (before roaming), monitored by AP1 (access device namely before roaming) and sent to AC, when switching (during roaming), then send AP2 (access device namely after roaming) to by AC.
There are two defects in above technical scheme:
If one when initial access AP1 also do not get IP address of terminal, terminal have already been mades switching, then after handover, the upper IP address that would not have terminal of AC, AP2 is upper can not carry out transmission proxy terminal transmission ARP message or terminal switch message.
Two, the flow process obtaining terminal IP in this patent relates to AP1, AC, AP2 tri-network equipments, and flow process is more, and efficiency is lower.
Due to the two problems of above-mentioned patent, if the problem not sending the service disconnection that ARP causes during terminal roaming is not solved thoroughly, and the method efficiency is lower.
Summary of the invention

Embodiment
For making technical scheme of the present invention clearly understand, now by reference to the accompanying drawings the present invention is described in further details:
Embodiment 1
The embodiment of the present invention provides a kind of method realizing terminal roaming, the method adopts WAP (wireless access point) initiatively to send the mode of gratuitous ARP packet or self-defining notification broadcast message, when solving terminal roaming, the problem of service interruption caused because terminal does not send ARP message.
Terminal can carry out wireless traffic after connecting upper WAP (wireless access point), and terminal is including but not limited to the PC that can get online without being tethered to a cable, mobile phone etc.WAP (wireless access point) is connected with the corresponding ports of switching equipment, after terminal switch to new WAP (wireless access point), it leads to the port of switching equipment and will change thereupon, and the corresponding relation therefore changing terminal and switching equipment outbound port in time can keep radio services to transmit not interrupting.
Fig. 1 is the network topological diagram of the embodiment of the present invention.In Fig. 1, in the wireless network environment at terminal place, be deployed with two WAP (wireless access point): WAP (wireless access point) 1 and WAP (wireless access point) 2, two WAP (wireless access point) are connected with switching equipment respectively, WAP (wireless access point) 1 is connected with the port one of switching equipment, and WAP (wireless access point) 2 is connected with the port 2 of switching equipment.Before terminal is not roamed, terminal is got online without being tethered to a cable by connecting WAP (wireless access point) 1, and after terminal is roamed, terminal connects WAP (wireless access point) 2, now need switching equipment by former be the message of terminal by its port one sending destination location, be switched to port 2 and send.
Fig. 2 is the flow chart realizing terminal roaming method of the embodiment of the present invention, and the method concrete operations flow process is:
S201: after terminal success is switched to WAP (wireless access point) 2 from WAP (wireless access point) 1, WAP (wireless access point) 2, according to the switching connection message of terminal, obtains and preserves the MAC Address of terminal.Wherein, described terminal switch connection message is association request message or reassociation requests message.
S202: WAP (wireless access point) 2, according to the terminal MAC address preserved, is resolved the message from this terminal, obtained the IP address of this terminal.In this step, WAP (wireless access point) 2 is monitored the IP message carrying out self terminal, as connected online http request message; Thus obtain the IP address of terminal.
S203: when behind the IP address getting terminal, WAP (wireless access point) 2 sends address notification message, described address notification message is gratuitous ARP packet or self-defined a kind of notification broadcast message.The content of described address notification message comprises the MAC Address of terminal and the IP address of terminal.
After WAP (wireless access point) 2 sends gratuitous ARP packet or self-defining notification broadcast message, no longer repeat to send gratuitous ARP packet or self-defining notification broadcast message.
S204: switching equipment when receiving the gratuitous ARP packet or self-defining notification broadcast message that WAP (wireless access point) 2 sends, scheduler transmit described in outbound port corresponding to the MAC Address of terminal.In this step, switching equipment is that in this locality preservation being transmitted, the outbound port corresponding with terminal MAC address, is updated to port 2 by port one.
According to the MAC Address of terminal after renewal and transmitting of corresponding outbound port (i.e. port 2), switching equipment can send to the message of terminal, correct is sent by WAP (wireless access point) 2, and can not send by WAP (wireless access point) 1 interruption causing radio services again.
Embodiment 2
