Description
Technical field
The present invention relates to data communication field, especially a kind of method, AP and AC for realizing wireless terminal roaming detection.
Background technique
The current thin AP network architecture, by AC (Acess controler, wireless controller) and AP (Acesss point,
Wireless access point) it collectively constitutes, using WLAN (Wireless Local Area Networks, the wireless office of centralized management
Domain net) in system, AC can issue WLAN signal to AP, terminal (station or STA, such as mobile phone, PAD) connects AP release
WLAN signal is surfed the Internet.
Under the thin AP network architecture, there are concentration forwarding and local forwarding, in concentrating repeating process, the end AP air message system
One passes through CAPWAP (Control And Provisioning of Wireless Access Points Protocol
Specification, the control of wireless access point and configuration protocol) encapsulation is sent to AC, then is forwarded by AC；Locally turning
During hair, data message carries out two layers of forwarding on AP, and wireless management message still needs to be sent to AC processing.
Under the thin AP network architecture, terminal can carry out radio roaming, i.e. terminal is being moved to facing for two AP coverage areas
When battery limit (BL) domain, it is associated with new AP and is associated with original AP disconnection, and keep continual network connection in the process.
If user's virtual LAN VLAN configuration of new and old AP is identical, referred to as two layers roaming；If the user vlan of new and old AP configures difference,
Referred to as three layers roaming.Roaming successfully under the premise of, no matter two layers or three layers roam, the IP address of terminal is constant, into
Capable session will not be interrupted.
But in actual deployment, for various reasons, the roaming of terminal is likely to occur failure.Such as: terminal cross
Same roaming group is not added in different AC and these AC；The trawl performance of terminal is not supported to roam；There are particularity not to allow by AP
It diffuses out or diffuses in；Signal blind zone is larger between AP, and list item of the terminal on former AP has timed out.
When two layers of roaming failure of terminal, since original gateway is still reachable, original IP address is can be used in terminal
Address Resolution Protocol ARP is sent to request and continue to communicate；But when three layers of roaming failure occurs, terminal, which is equivalent to, to be directly linked to newly
On AP, user vlan changes, and terminal can not be connected to original gateway, old IP address cannot be used to continue to communicate.
Terminal may be attempted to retransmit DHCP (Dynamic Host when that can not continue communication
Configuration Protocol, dynamic host configuration protocol) it requests or disconnects reconnection, to restore to communicate, but this is not assisted
Behavior as defined in discussing.Since even if roaming failure, SSID (Service Set Identifier, the service of terminal association occurs
Set identifier) will not still it change, certain terminals will be considered that oneself can still be communicated with former IP address, do not applied for IP address again, led
Terminal is caused lasting cutout, affect experience occur.
Existing technology realization is optimized from terminal side mostly, the detection of connectivity and recovery after realizing roaming failure,
But since wireless terminal is many kinds of, and there is the non-standard terminal for being largely difficult to upgrade in production environment, such as Medical trolley, storehouse
Pipe scanner, PDA etc., the optimization carried out from terminal side do not have universality, not can guarantee and do not overflow in entire wireless network
Swim the problem that unsuccessfully stops.
