Management of the first LC. Example 2

Embodiments of the present invention provide a method for managing a WTP of a wireless terminal station. See Figure 3, where the method includes:

Step 201: The second WTP sends an investigation request carrying the identifier of the second WTP to at least one first-WTP;

In the area where the WLAN is deployed, a WTP with local coordinator capability is set to LC in each first preset range, and the LC is used to manage at least one first WTP in the first preset range. . In the embodiment of the present invention, the second WTP cannot send the message between the different WTPs, so that the second WTP cannot discover the first LC. Therefore, the second WTP sends an investigation request carrying the identifier of the second WTP to the at least one first WTP, so that Obtaining the identifier of the first LC by using the first WTP. The first WTP may be the WTP that has been added to the first LC, or may be the WTP that is not added to the first LC. The first WTP may also be the first LC. The second WTP is the WTP to be added to the LC, the at least one first WTP is the WTP in the second preset range around the second WTP, and the first WTP in the second preset range can receive the second WTP transmission survey. request. In the embodiment of the present invention, the hop count of the message transmitted between the first LC and the second WTP is less than the preset hop count, and the preset hop count may be set and changed according to requirements, or the first LC is The communication signal quality of the second WTP is greater than a preset threshold, and the preset threshold may be set and changed according to requirements, or the working frequency of the first LC is consistent with the working frequency of the second WTP.

The identifier of the second WTP may be any identifier that identifies the second WTP. In the embodiment of the present invention, the identifier of the second WTP is not specifically limited. For example, the identifier of the second WTP is the Media Access Control (MAC) address of the second WTP, and the like. Moreover, the first preset range and the second preset range may be set and changed according to requirements. In the embodiment of the present invention, the first preset range and the second preset range are not specifically limited.

Step 202: The at least one first WTP receives the survey request sent by the second WTP, and sends the management information to the second WTP according to the identifier of the second WTP.

The management information also carries the identifier of the first WTP, and the management information may also carry the identifier of the first LC, where the first LC is the LC to which the first WTP has been added. Moreover, the management information may also carry the identity information of the first WTP, where the identity information is used to identify whether the first WTP supports the local coordinator capability. If the first WTP supports local coordinator capabilities, the first LC may set the first WTP as the backup LC.

The first LC sends the saved local information to the backup LC for backup at the first preset time. The local information includes the AC, WTP information, and other backup LC identifiers that are accessed in the first LC management range. , backup strategy, synchronization strategy, and measurement strategy. And the first preset time can be set and changed as needed.

If the first WTP is added to the LC, but the LC added by the first WTP is not the first LC, but the second LC, step 202 may be specifically:

The first WTP receives the survey request sent by the second WTP, and obtains the identifier of the second WTP according to the survey request; the first WTP obtains the identifier of the second LC that has been added, and sends the management information to the second according to the identifier of the second WTP. WTP, the management information carries the identifier of the first WTP and the identifier of the second LC.

If the first WTP is not added to the LC, step 202 may be specifically:

The first WTP receives the survey request sent by the second WTP, and obtains the second request according to the survey request.

The WTP sends the management information according to the identifier of the second WTP, and the management information carries the identifier of the first WTP, and the management information may also carry the invalid identifier.

The invalid identifier may be any address specified in advance; for example, the invalid identifier is a broadcast address, Multicast address, all 0s, all fs, or other specific addresses. The identifier of the first WTP may be any identifier that identifies the first WTP, and the identifier of the second LC may be any identifier that identifies the second LC. In the embodiment of the present invention, the identifier of the first WTP and the second LC The logo is not specifically limited. For example, the identifier of the first WTP is the MAC address of the first WTP or the like. The identifier of the second LC is the MAC address of the second LC, and the like.

In the embodiment of the present invention, the second WTP sends a survey request to the at least one first WTP to obtain the first LC in the range of the area where the second WTP is located, and if the first WTP is the first LC, step 202 may Specifically:

The first WTP receives the survey request sent by the second WTP, and obtains the identifier of the second WTP according to the survey request; and sends the management information to the second WTP according to the identifier of the second WTP, where the management information carries the identifier of the first WTP and the first WTP A WTP logo.

Step 203: The second WTP receives the management information sent by the at least one first WTP, and determines whether the identifier of the first LC can be obtained according to the management information, if yes, step 204 is performed, and if no, step 207 is performed;

The step of determining, in step 203, whether the identifier of the first LC can be obtained according to the management information may include the following steps (1) to (3):

(1), the second WTP determines whether the management information carries the identifier of the first LC, if yes, step (2) is performed, if no, it is determined that the identifier of the first LC is not obtained according to the management information, and step 207 is performed;

If the management information carries the identifier of the first LC, the second WTP determines that the LC exists in the periphery of the second WTP, and performs step (2); if the management information does not carry the identifier of the first LC, the second WTP determines the second There is no LC around the WTP. Therefore, the second WTP determines that the identifier of the first LC cannot be obtained according to the management information.

(2) The second WTP determines whether the identifier of the first LC is an invalid identifier, and if not, performs step (3); if yes, the second WTP determines that the identifier of the first LC is not obtained according to the management information, and step 207 is performed. ;

The second WTP stores the invalid identifier in advance, and the second WTP compares the identifier of the first LC with the stored invalid identifier. If the identifier of the first LC and the invalid identifier are the same, the second WTP determines the first LC. The identifier is an invalid identifier. If the identifier of the first LC and the invalid identifier are different, the second WTP determines that the identifier of the first LC is not an invalid identifier.

(3), the second WTP determines whether the identifier of the first WTP and the identifier of the first LC are the same, if In the same step, step 204 is performed. If the second WTP determines that the identifier of the first LC is not obtained according to the management information, step 207 is performed.

Wherein, if the first LC exists in the periphery of the first WTP, and the first WTP has been added to the first LC. The management information sent by the first WTP carries the identifier of the first WTP and the identifier of the first LC; and if the identifier of the first WTP is the same as the identifier of the first LC, the second WTP determines that the first WTP is the current one. The first LC, that is, the second WTP, can receive the management information transmitted by the first LC. The second WTP can acquire the first LC according to the management information of the first WTP. However, if the identifier of the first WTP is different from the identifier of the first LC, the second WTP determines that the first LC exists in the periphery, but the second WTP does not receive the management information sent by the first LC, that is, the second WTP according to the management information. The first LC is not available.

Step 204: The second WTP obtains the identifier of the first LC according to the management information.

The management information carries the identifier of the first LC, and the second WTP extracts the identifier of the first LC from the management information.

Step 205: The second WTP sends an add request carrying the identifier of the second WTP to the first LC according to the identifier of the first LC.

If the second WTP obtains the identifier of the first LC, the second WTP joins the first LC, so that the first LC manages the second WTP.

Step 206: The first LC receives the join request sent by the second WTP, and manages the second WTP according to the identifier of the second WTP.

Specifically, the first LC receives the join request sent by the second WTP, and establishes a first CAPWAP extended tunnel with the second WTP, where the first LC may perform channel measurement statistics, QoS service statistics, and the like for the second WTP; A CAPWAP extended tunnel, the first LC may send configuration information to the second WTP to configure the channel of the second WTP and the information of the wireless station.

Step 207: The second WTP sets itself as the first LC.

Specifically, if the second WTP cannot obtain the identifier of the first LC according to the management information, or the second WTP receives the exit request of the identifier of the first LC sent by the first LC, the second WTP sets itself to the first An LC.

When the first LC is to exit the WLAN, or when the first LC is abnormal, or when the first LC receives the indication command sent by the AC, the first LC issues an exit request to all the first LC management scopes. WTP, the exit request carries at least the identifier of the first LC, and the exit request may further carry the identifier of the third LC, after the third LC is the first LC exit, instead of the first LC pair LC managed by all WTPs within the scope of LC management. The first LC leaves the WLAN network, or the first LC is aborted to the normal WTP, or the first LC is abdicated to the backup LC.

If the exit request only carries the identifier of the first LC, the other WTPs in the network may compete to become the third LC; and if the exit request carries the identifier of the first LC and the identifier of the third LC, directly by the third The LC manages the WTP managed by the first LC.

It should be noted that, when the first LC is abdicated, the backup LC has the capability of preferentially becoming the third LC.

Further, if the second WTP cannot obtain the identifier of the first LC according to the management information, the second WTP may also obtain the identifier of the second LC, and send a join request to the second LC according to the identifier of the second LC, if the second The LC can receive the join request sent by the second WTP, the second LC can add the second WTP to the second LC, and manage the second WTP; if the second LC cannot receive the join request sent by the second WTP, The second LC does not add the second WTP to the second LC, nor does it manage the second WTP.

In the embodiment of the present invention, the WTP is managed by the AC, and the WTP is managed by the LC. The WTP that needs to be managed acquires the identifier of the first LC according to the management information sent by other WTPs, so that the first LC can be found and accepted.

In the embodiment of the present invention, the second WTP cannot obtain the identifier of the first LC by using the first WTP because the second WTP cannot discover the first LC because the message cannot be directly transmitted between different WTPs.

The first WTP may be a WTP that has been added to the first LC, or a WTP that is not added to the first LC. The first WTP may also be the first LC. At least one first WTP is a WTP in a second preset range around the second WTP.

In the embodiment of the present invention, the hop count of the message transmitted between the first LC and the second WTP is less than the preset hop count, and the preset hop count may be set and changed according to requirements, or the first LC is The quality of the communication signal with the second WTP is greater than a preset threshold, and the preset threshold may be set and changed according to requirements, or the working frequency of the first LC is consistent with the working frequency of the second WTP.

The first WTP obtains the identifier of the second LC that has been added every second preset time, and broadcasts the management information of the identifier of the first WTP and the identifier of the second LC.

The LC in the first range in which the first WTP is located may be changed at any time. Therefore, the first WTP obtains the identifier of the added second LC every second preset time. For example, the LC in the first range in which the first WTP is located before the second preset time is LC1, and the LC in the first range in which the first WTP is located at the current moment is LC2.

The identifier of the first WTP may be any identifier that identifies the first WTP, and the identifier of the second LC may be any identifier that identifies the second LC.

For example, the identifier of the first WTP is the MAC address of the first WTP, and the identifier of the second LC is the MAC address of the second LC. Moreover, the second preset time may be set and changed as needed. In the embodiment of the present invention, the second preset time is not specifically limited.

If the first WTP is not added to the LC, step 301 may be specifically:

The first WTP broadcasts the management information every second preset time, and the management information also carries the identifier of the first WTP, and the management information may also carry the invalid identifier.

The invalid identifier may be any address specified in advance; for example, the invalid identifier is a broadcast address, a multicast address, all 0s, all fs, or other specific addresses.

In the embodiment of the present invention, the second WTP is configured to obtain the first LC in the range of the area where the second WTP is located by using the management information of the first WTP broadcast, and if the first WTP is the first LC, the step 301 may be specifically :

The first WTP broadcasts the management information of the identifier of the first WTP and the identifier of the first WTP every second preset time.

Step 302: The second WTP receives the management information of the at least one first WTP broadcast, and determines whether the identifier of the first LC can be obtained according to the management information, if yes, step 303 is performed, and if no, step 306 is performed; The step of determining in step 303 whether the identifier of the first LC can be acquired according to the management information may include the following steps (1) to (3):

(1), the second WTP determines whether the management information carries the identifier of the first LC, if yes, step (2) is performed, if no, it is determined that the identifier of the first LC is not obtained according to the management information, and step 306 is performed;

(2) The second WTP determines whether the identifier of the first LC is an invalid identifier, and if not, performs step (3); if yes, the second WTP determines that the identifier of the first LC is not obtained according to the management information, and step 306 is performed. ;

The second WTP stores an invalid identifier in advance, and the second WTP compares the identifier of the second LC with the stored invalid identifier. If the identifier of the first LC and the invalid identifier are the same, the second WTP determines the first LC. The identifier is an invalid identifier. If the identifier of the first LC and the invalid identifier are different, the second WTP determines that the identifier of the first LC is not an invalid identifier.

(3) The second WTP determines whether the identifier of the first WTP and the identifier of the first LC are the same. If they are the same, step 303 is performed. If the second WTP is different, the second WTP determines that the identifier of the first LC is not obtained according to the management information, and performs Step 306;

Step 303: The second WTP obtains the identifier of the first LC according to the management information.

Step 304: The second WTP sends the identifier carrying the identifier of the second WTP according to the identifier of the first LC. Incoming request to the first LC;

Step 305: The first LC receives the join request sent by the second WTP, and manages the second WTP according to the identifier of the second WTP.

Step 306: The second WTP sets itself as the first LC;

When the first LC is to exit the WLAN, or when the first LC is abnormal, or when the first LC receives the indication command sent by the AC, the first LC issues an exit request to all the first LC management scopes. WTP, the exit request carries at least the identifier of the first LC, and the exit request may further carry the identifier of the third LC. After the third LC is the first LC exit, instead of the first LC, all the WTPs in the first LC management range are replaced. Managed LC. The first LC leaves the WLAN network, or the first LC is aborted to the normal WTP, or the first LC is abdicated to the backup LC.
