Set Identifier, BSSID) be changed to the 2nd BSSID after, obtain the corresponding first AP information of the first BSSID and second
The corresponding 2nd AP information of BSSID.
Currently, terminal is insensitive for roaming event, roaming does not influence terminal and normally accesses network, to
It is also transparent for family, also monitors interface to application developer without providing roaming event.Therefore, in order in terminal
Identify roaming event, just the BSSID of the WLAN of necessary real-time monitoring terminal connection, can provide a buffering area and use
To record the result of real time monitoring.
Since terminal can not get the name information of the AP currently connected, can only be distinguished by BSSID.But actually
Different AP cannot be distinguished in BSSID, because the different frequency range signal of the same AP can be indicated using different BSSID.Such as
The 2.4G signals of the same AP and the BSSID of 5G signals are different, and a terminal is switched to 5G signals from 2.4G signals, although
The BSSID shown in terminal is different, and that actually it is connected is the same AP.
Therefore, monitor terminal connection WLAN the first BSSID be changed to the 2nd BSSID after, obtain first
The corresponding AP information of BSSID and the corresponding AP information of the 2nd BSSID, the corresponding AP information of the first BSSID are defined as the first AP letters
Breath, the corresponding AP information of the 2nd BSSID are defined as the 2nd AP information.
S12：Determine whether terminal roams according to the first AP information and the 2nd AP information.
Monitor terminal connection WLAN the first BSSID be changed to the 2nd BSSID after, cannot directly determine end
End roams, but to be further determined according to the first AP information and the 2nd AP information.

Determine the first signal strength values before terminal roaming and the second signal intensity value after roaming.
When receiving signal, meeting tracer signal intensity value can get the signal strength before terminal roaming and overflow terminal
Signal strength after trip, wherein the signal strength before terminal roaming is defined as the first signal strength, and the signal after terminal roaming is strong
Degree is defined as second signal intensity.
S14：Determine the packet loss information in the beginning and ending time.
Terminal is during roaming, that is, from during an AP is switched to another AP, it may occur that packet loss, because
This, it is thus necessary to determine that the packet loss information within the terminal roaming beginning and ending time.
S15：According to the first AP information, the 2nd AP information, the first signal strength values, second signal intensity value, the beginning and ending time,
Switching time and packet loss information generate the roaming event of terminal.
The first AP information, the 2nd AP information, the first signal strength values, the second signal intensity got through the above steps
Value, beginning and ending time, switching time and packet loss information, so that it may to generate the roaming event of terminal.

Since the AP information of each AP can be preserved on AC, terminal can obtain the corresponding AP of BSSID with AC communications
Information, wherein terminal can be, but not limited to communicate to connect by telnet modes and AC.
If specifically, the first AP information includes the first name information and the first IP address of the first AP, the 2nd AP packets
The second name information and the second IP address for including the 2nd AP, then determine whether terminal is sent out according to the first AP information and the 2nd AP information
Raw roaming, specifically includes：It determines whether the first name information is identical as the second name information, and determines the first IP address and the
Whether two IP address are identical；If it is determined that the first name information is different from the second name information and the first IP address with the 2nd IP
Location is different, it is determined that terminal roams.
Each AP has name information and IP address on AC, can accurately determine one according to name information and IP address
Therefore a AP can determine whether terminal roams according to whether the name information of AP and IP address are identical.
Specifically, determining beginning and ending time and switching time that terminal roaming occurs, specifically include：By the media interviews of terminal
Control the address (Media Access Control, MAC) be sent to AC so that AC obtain terminal roaming occur beginning and ending time and
Terminal is sent to after switching time；Receive beginning and ending time and switching time that AC is sent.
This important indicator of the beginning and ending time and switching time of terminal roaming is also that can not get in terminal itself, root
It is obtained from AC according to the MAC Address of terminal.
Optionally, terminal can be with：Periodic broadcasting heartbeat detection message；And receive heartbeat response message.
Heartbeat detection message can be ping orders, after AP receives heartbeat detection message, can reply heartbeat response report
Text is received by terminal.
Correspondingly, the packet loss information in the beginning and ending time is determined in above-mentioned S14, is specifically included：It obtains in the beginning and ending time and receives
The heartbeat response message arrived obtains selected response message；Delay and sequence of message number are obtained from selected response message；Root
Packet loss is determined according to the sequence of message number in selected message；Combination Delay and packet loss obtain the letter of the packet loss in the beginning and ending time
Breath.
When determining packet loss information of the terminal within the beginning and ending time, it is necessary first to obtain the heartbeat received in the beginning and ending time
Response message, these messages are just needed message, can be defined as selected response message.Heartbeat response report is exemplified below
The main contents that text includes.
For example, the heartbeat response message main contents that terminal receives are as follows：
64bytes from 192.168.0.1(192.168.0.1):Icmp_seq=1ttl=50time=177ms；
64bytes from 192.168.0.1(192.168.0.1):Icmp_seq=3ttl=50time=156ms.
As it can be seen that can be with time delay information and sequence of message number, therefore in heartbeat response message, terminal can therefrom directly
Delay is got, but packet loss cannot be directly obtained, due to carrying sequence of message number in heartbeat response message,
Packet loss can be calculated according to sequence of message, wherein sequence of message number can use the icmp_ in above-mentioned heartbeat response message
Seq fields indicate.
Optionally, further include：The roaming track of terminal is formed according to the roaming event of terminal；The roaming rail of display terminal
