Description
Technical Field
The present invention relates to the technical field, and in particular, to a wireless roaming optimization method, system, device and storage medium.
Background
802.11r is a wireless roaming protocol aimed at reducing the time required for authentication when a STA (wireless client) roams.
The following describes 802.11r based wireless roaming procedures in connection with specific examples.
Assuming that the STA accesses the AP1 first and then moves to the roaming process from the AP1 to the AP2 in the direction of the AP2 as an example, the roaming switching process from the AP1 to the AP2 of the STA is shown in fig. 1, and includes the following steps:
S01-S04: the STA and the AP1 communicate to complete security authentication and association;
S05-S08: the STA and the AP1 complete key negotiation through four-way handshake, and access to the AP1 is successful.
S09-S11: AP1 sends a node add notify to other APs in the lan, and distributes a key (PMK-R1) with other APs (e.g., AP 2).
S12-S15: and the STA detects that the signal strength between the STA and the AP1 is weakened to a switching threshold value in the process of moving towards the AP2, completes complete security authentication and re-association for the AP2 communication, and completes key negotiation by using a key distributed by the AP1 in the process, thereby successfully accessing the AP2.
S16: the STA disassociates from AP1.
It can be seen that when the STA roams from the AP1 to the AP2, the STA can successfully access to the AP2 only by performing security authentication and association with the AP2 (and implementing key negotiation in the process), and no four-section handshake is required to be separately executed for key negotiation, so that the access process consumes less time.
However, the above wireless roaming procedure is not suitable for a scenario where APs are too close together, for example, in a small family, a problem may occur in that wireless roaming of STAs cannot be triggered due to the close distance between APs. For example, assuming that the distance between the AP1 and the AP2 is relatively close, when the STA moves from the AP1 to the AP2, the wireless roaming of the STA cannot be triggered because the signal strength between the STA and the AP1 is not sufficiently attenuated, and the handoff threshold cannot be reached.

A non-transitory computer readable storage medium storing instructions that, when executed by a processor, cause the processor to perform steps in a wireless roaming optimization method as described above.

Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the embodiment of the invention, for a wireless network with a relatively close distance between APs (Access points), such as a wireless network of a small family, aiming at the problem that wireless roaming of an STA cannot be triggered due to too close distance between APs in the wireless network, a corresponding relation between signal strength attenuation and transmission power reduction is summarized through experimental data of an actual scene, and a down-regulation operation is performed on the transmission power of each AP according to the corresponding relation, so that the wireless roaming of the STA between close-range APs can be triggered.
The method provided by the invention is specifically described below with reference to specific examples:
referring to fig. 2, fig. 2 is a flowchart of a wireless roaming optimization method provided in an embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 2, and specifically includes the following steps:
step 201, executing the following wireless roaming optimization operations from step 202 to step 204 for each AP in the roaming group;
step 202, acquiring surrounding AP information scanned by the AP;
step 203, judging whether the AP meets the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP;
and 204, when the AP does not meet the short-range wireless roaming condition, determining the maximum transmission power allowed by the AP and corresponding to the AP and meeting the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP and the corresponding relation between the preset signal intensity attenuation amount and the transmission power reduction amount, and informing the maximum transmission power to the AP so that the AP can adjust the transmission power down to be equal to or smaller than the maximum transmission power.
In the embodiment of the present invention, when the AP satisfies the short-range wireless roaming condition, it is indicated that the STA may trigger wireless roaming when moving from the AP to other APs in the roaming group, so that the operations of determining the maximum transmit power allowed by the AP and satisfying the short-range wireless roaming condition, and adjusting the transmit power to be equal to or less than the maximum transmit power in step 204 are not required.
As can be seen from the method shown in fig. 2, in this embodiment, when it is determined that the AP does not meet the short-range wireless roaming condition according to the signal strength included in the surrounding AP information scanned by each AP in the roaming group, the maximum transmission power allowed by the AP and meeting the short-range wireless roaming condition is determined with reference to the correspondence between the pre-configured signal strength attenuation amount and the transmission power reduction amount, so that the transmission power of the AP is reduced to be equal to or less than the maximum transmission power, so that the signal strength between the AP and other APs in the roaming group is reduced to be able to meet the short-range wireless roaming condition, and therefore, the problem that wireless roaming between the APs in the short-range can not be triggered by the STA can be solved.
Referring to fig. 3, fig. 3 is a flowchart of a wireless roaming optimization method provided by a second embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, which belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 3, and specifically includes the following steps:
Step 301, when it is determined that the roaming group meets the wireless roaming optimization triggering condition, performing the following wireless roaming optimization operations of step 302 to step 304 on each AP in the roaming group.
The above step 301 is a detailed refinement of step 201 shown in fig. 2.
In the embodiment of the present invention, when it is determined that the roaming group does not satisfy the wireless roaming optimization triggering condition, the wireless roaming optimization operation is prohibited from being executed for each AP in the roaming group, that is, the wireless roaming optimization operation of the following steps 302 to 304 is not executed for the AP.
Step 302, acquiring surrounding AP information scanned by the AP;
step 303, judging whether the AP meets the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP;
and step 304, when the AP does not meet the short-range wireless roaming condition, determining the maximum transmission power allowed by the AP and corresponding to the AP and meeting the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP and the corresponding relation between the preset signal intensity attenuation amount and the transmission power reduction amount, and informing the maximum transmission power to the AP so that the AP can adjust the transmission power down to be equal to or smaller than the maximum transmission power.
In the embodiment of the present invention, when the AP satisfies the short-range wireless roaming condition, it is indicated that the STA may trigger wireless roaming when moving from the AP to other APs in the roaming group, so that the operations of determining the maximum transmit power allowed by the AP and satisfying the short-range wireless roaming condition in step 304, and adjusting the transmit power to be equal to or less than the maximum transmit power are not required.
As can be seen from the method shown in fig. 3, compared with the embodiment shown in fig. 2, in this embodiment, in addition to solving the problem that wireless roaming between STAs in close range APs cannot be triggered, the time for implementing wireless roaming optimization on APs in the roaming group is controlled by a wireless roaming optimization triggering condition, so that frequent execution of wireless roaming optimization operations on the roaming group can be avoided.
Referring to fig. 4, fig. 4 is a flowchart of a wireless roaming optimization method provided by a third embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 4, and specifically includes the following steps:
step 4011, receiving a roaming optimization trigger instruction;
in the embodiment of the invention, a function button, such as "802.11r optimization", can be added in the group configuration of the AC, and the user can trigger a roaming optimization triggering instruction by clicking the function button.
Step 4012, judging whether the number of APs in the roaming group is greater than 1, if yes, executing step 4013, otherwise, executing step 4014;
step 4013, determining that the roaming group meets the wireless roaming optimization triggering condition, and executing the following wireless roaming optimization operations of step 402 to step 404 for each AP in the roaming group.
Step 4014, determining that the roaming group does not meet the wireless roaming optimization triggering condition, and ending the flow.
In this embodiment, when it is determined that the roaming group meets the wireless roaming optimization triggering condition, the wireless roaming optimization operation is prohibited from being performed on each AP in the roaming group, that is, the following wireless roaming optimization operations of step 402 to step 404 are not performed on the AP.
The above steps 4011 through 4014 are specific refinements of step 301 shown in fig. 3.
Step 402, acquiring surrounding AP information scanned by the AP;
step 403, judging whether the AP satisfies the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP;
and step 404, when the AP does not meet the short-range wireless roaming condition, determining the maximum transmission power allowed by the AP to meet the short-range wireless roaming condition according to the signal intensity and the corresponding relation between the preset signal intensity attenuation amount and the transmission power reduction amount included in the surrounding AP information scanned by the AP, and informing the maximum transmission power to the AP, so that the AP can adjust the transmission power down to be equal to or smaller than the maximum transmission power.
In the embodiment of the present invention, when the AP satisfies the short-range wireless roaming condition, it is indicated that the STA may trigger wireless roaming when moving from the AP to other APs in the roaming group, so that the operations of determining the maximum transmit power allowed by the AP and satisfying the short-range wireless roaming condition, and adjusting the transmit power to be equal to or less than the maximum transmit power in step 404 are not required.
As can be seen from the method shown in fig. 4, compared with the embodiment shown in fig. 3, the present embodiment can solve the problem that wireless roaming between STAs in close range APs cannot be triggered, and determine that the roaming group meets the wireless roaming optimization triggering condition by receiving a roaming optimization triggering instruction and determining whether the number of APs in the roaming group is greater than 1 after receiving the roaming optimization triggering instruction, so as to avoid executing unnecessary wireless roaming optimization operations on the roaming group.
Referring to fig. 5, fig. 5 is a flowchart of a wireless roaming optimization method provided by a fourth embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 5, and specifically includes the following steps:
Step 501, selecting an AP that has not been selected from the roaming group at intervals of a preset time period, and performing the following wireless roaming optimization operations from step 502 to step 504 on the AP;
in this embodiment, the preset time period is a preset time value, which can be empirically set, for example, 6 seconds. By selecting one AP in the roaming group for wireless roaming optimization operation at intervals of a preset time period, multiple APs can be prevented from scanning surrounding APs at the same time, and therefore the success rate and the integrity of scanning are effectively increased.
Step 502, acquiring surrounding AP information scanned by the AP;
step 503, judging whether the AP satisfies the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP;
and step 504, when the AP does not meet the short-range wireless roaming condition, determining the maximum transmission power allowed by the AP to meet the short-range wireless roaming condition according to the signal strength and the corresponding relation between the preset signal strength attenuation amount and the transmission power reduction amount included in the surrounding AP information scanned by the AP, and informing the maximum transmission power to the AP, so that the AP can adjust the transmission power down to be equal to or smaller than the maximum transmission power.
In the embodiment of the present invention, when the AP satisfies the short-range wireless roaming condition, it is indicated that the STA may trigger wireless roaming when moving from the AP to other APs in the roaming group, so that operations such as determining the maximum transmit power allowed by the AP and satisfying the short-range wireless roaming condition, and adjusting the transmit power to be equal to or less than the maximum transmit power in step 504 are not required.
As can be seen from the method shown in fig. 5, compared with the embodiment shown in fig. 2, the present embodiment can solve the problem that wireless roaming between STAs in a short range AP cannot be triggered, and further control the number of APs that perform scanning on surrounding APs simultaneously by selecting an AP that has not been selected from the roaming group for wireless roaming optimization at intervals of a preset time period, so as to increase the success rate and integrity of scanning.
Referring to fig. 6, fig. 6 is a flowchart of a wireless roaming optimization method provided in a fifth embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 6, and specifically includes the following steps:
step 601, setting a pause configuration flag corresponding to each AP in the roaming group, so as to prohibit the AC from executing configuration operations other than the configuration operations in the wireless roaming optimization operation process on the AP; and performing the following wireless roaming optimization operations of step 602 to step 604 for the AP;
In this embodiment, since the configuration operation of downregulating the transmitting power of the AP may be involved in the process of performing the wireless roaming optimization operation on the AP, if the user configures the AP in other ways at this time, the two configurations may collide, and in order to avoid such a collision problem, the AP does not respond to any other configuration instruction for the AP in the wireless roaming optimization process by setting the suspend configuration flag corresponding to the AP.
Step 602, acquiring surrounding AP information scanned by the AP;
step 603, judging whether the AP satisfies the short-range wireless roaming condition according to the signal strength contained in the surrounding AP information scanned by the AP;
step 604, when the AP does not meet the short-range wireless roaming condition, determining the maximum transmission power allowed by the AP and corresponding to the AP to meet the short-range wireless roaming condition according to the signal strength and the corresponding relation between the pre-configured signal strength attenuation amount and the transmission power reduction amount included in the surrounding AP information scanned by the AP, and notifying the maximum transmission power to the AP, so that the AP can adjust the transmission power down to be equal to or less than the maximum transmission power;
in the embodiment of the present invention, when the AP satisfies the short-range wireless roaming condition, it is indicated that the STA may trigger wireless roaming when moving from the AP to other APs in the roaming group, so that operations such as determining the maximum transmit power allowed by the AP and satisfying the short-range wireless roaming condition, and adjusting the transmit power to be equal to or less than the maximum transmit power in step 604 are not required.
Step 605, deleting the pause configuration flag corresponding to the AP, so as to allow the AC to perform configuration operations on the AP except for the configuration operations in the wireless roaming optimization operation process.
In this embodiment, before performing the wireless roaming optimization operation on each AP in the roaming group, the suspend configuration flag corresponding to the AP is set, so that the AP does not respond to any configuration instruction for the AP any more, and after performing the wireless roaming optimization operation on each AP in the roaming group, the opposite operation needs to be performed, i.e. the suspend configuration flag corresponding to the AP is deleted, so that the AP may respond to any other configuration instruction for the AP.
As can be seen from the method shown in fig. 6, compared with the embodiment shown in fig. 2, this embodiment can solve the problem that wireless roaming between STAs in close range APs cannot be triggered, and also control the response of the AP to any other configuration instruction for the AP in the process of performing wireless roaming optimization for the AP by setting and deleting the suspend configuration flag corresponding to the AP, so as to avoid configuration conflict.
Referring to fig. 7, fig. 7 is a flowchart of a wireless roaming optimization method provided in a sixth embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 7, and specifically includes the following steps:
Step 701, performing the following wireless roaming optimization operations from step 7021 to step 704 for each AP in the roaming group:
step 7021, issuing a wireless roaming optimization instruction to the AP, so that the AP scans surrounding AP information and reports the scanned surrounding AP information;
step 7022, receiving surrounding AP information reported by the AP.
In this embodiment, a new capwap protocol is added between the AC and the AP, and is used for the AC to issue a wireless roaming optimization instruction to the AP, and the AP reports surrounding AP information to the AC.
The above steps 7021 to 7022 are specific refinements of step 202 shown in fig. 2.
Step 703, judging whether the AP satisfies the short-range wireless roaming condition according to the signal strength contained in the surrounding AP information scanned by the AP;
and step 704, when the AP does not meet the short-range wireless roaming condition, determining the maximum transmission power allowed by the AP to meet the short-range wireless roaming condition according to the signal intensity and the corresponding relation between the preset signal intensity attenuation amount and the transmission power reduction amount included in the surrounding AP information scanned by the AP, and informing the maximum transmission power to the AP, so that the AP can adjust the transmission power down to be equal to or smaller than the maximum transmission power.
In the embodiment of the present invention, when the AP satisfies the short-range wireless roaming condition, it is indicated that the STA may trigger wireless roaming when moving from the AP to other APs in the roaming group, so that it is not necessary to perform operations of determining the maximum transmission power allowed by the AP and satisfying the short-range wireless roaming condition, and adjusting the transmission power to be equal to or less than the maximum transmission power in step 704.
According to the method shown in fig. 7, compared with the embodiment shown in fig. 2, the embodiment can solve the problem that wireless roaming of STAs between APs in a short distance cannot be triggered, and a new capwap protocol is defined by adding, so that wireless roaming optimization communication between the AC and the AP can be realized, and control of wireless roaming optimization of the AC to the AP is ensured.
Referring to fig. 8, fig. 8 is a flowchart of a wireless roaming optimization method provided in a seventh embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 8, and specifically includes the following steps:
step 801, performing the following wireless roaming optimization operations from step 802 to step 804 for each AP in the roaming group:
Step 802, acquiring surrounding AP information scanned by the AP;
step 8031, judging whether the maximum signal intensity in the signal intensity contained in each surrounding AP information scanned by the AP is larger than a preset roaming switching threshold value, if so, executing step 8032, otherwise, executing step 8033;
step 8032, determining that the AP does not meet the short-range wireless roaming condition, and proceeding to step 804 for execution;
step 8033, determining that the AP meets the short-range wireless roaming condition, and ending the wireless roaming optimization operation of the AP;
in the embodiment of the invention, when the AP meets the short-range wireless roaming condition, the STA can trigger wireless roaming when moving from the AP to other APs in the roaming group, so that the wireless roaming optimization operation of the AP can be directly ended.
The above steps 8031 to 8033 are specific refinements of step 203 shown in fig. 2.
Step 804, determining the maximum transmitting power allowed by the AP to meet the short-range wireless roaming condition according to the signal intensity contained in the surrounding AP information scanned by the AP and the corresponding relation between the pre-configured signal intensity attenuation amount and the transmitting power reduction amount, and notifying the maximum transmitting power to the AP, so that the AP can adjust the transmitting power down to be equal to or smaller than the maximum transmitting power.
As can be seen from the method shown in fig. 8, compared with the embodiment shown in fig. 2, in this embodiment, in addition to solving the problem that wireless roaming between AP in close range cannot be triggered by STA, in the process of executing wireless roaming optimization operation on AP, signal intensity in each surrounding AP information scanned by AP is used to determine whether the AP satisfies the close range wireless roaming condition, if not, the wireless roaming optimization process is continued, and if so, the wireless roaming optimization process is ended, so that execution of unnecessary wireless roaming optimization operation can be avoided.
Referring to fig. 9, fig. 9 is a flowchart of a wireless roaming optimization method provided by an eighth embodiment of the present invention, where the method is applied to a wireless network, and the wireless network includes an AC and an AP under the AC, where the AP belongs to the same roaming group, and the method is specifically applied to the AC, as shown in fig. 9, and specifically includes the following steps:
step 901, performing the following wireless roaming optimization operations from step 902 to step 9045 for each AP in the roaming group:
step 902, acquiring surrounding AP information scanned by the AP;
step 903, judging whether the AP satisfies a short-range wireless roaming condition according to the signal strength included in each piece of surrounding AP information scanned by the AP;
Step 9041, when the AP does not satisfy the short-range wireless roaming condition, performing the following steps 9042 to 9045;
step 9042, calculating the signal strength difference between the maximum signal strength of the signal strengths included in the surrounding AP information scanned by the AP and the preset roaming switching threshold;
in this embodiment, the preset roaming switching threshold may be determined through a test in advance, for example, a mainstream 802.11 r-capable mobile phone may be selected to perform a wireless roaming test: configuring two APs, such as APx and APy, in a wireless network, and configuring the distance between the two APs so that the mobile phone does not roam when moving between the two APs; then, the mobile phone is firstly accessed into the APx and then slowly moves towards the APy, the transmitting power is gradually reduced on the APx through a command, when the mobile phone roams at the critical moment, the surrounding AP list is scanned once on the APx through the command, the signal intensity of the APy at the moment is obtained, and the signal intensity is used as the roaming threshold value of the mobile phone. The roaming threshold value of each mobile phone is obtained by the same method, and the minimum roaming threshold value is used as a preset switching threshold value.
Step 9043, determining the transmission power reduction corresponding to the signal strength difference according to the correspondence between the pre-configured signal strength attenuation and the transmission power reduction;
In this embodiment, the correspondence may be determined by testing, for example, the APx and the APy are separated by a suitable distance (which is slightly closer than that in the case of normal roaming networking, mainly considering the situation that the distance between two APs in a small family is not very far), firstly, the signal intensity of the APy is obtained by scanning the surrounding AP list once through a command on the APx, the transmitting power value of the APx at this time is recorded, then the transmitting power of the APx is gradually reduced through a command, and each time the transmitting power is reduced, the surrounding AP list is scanned on the APx, and the signal intensity of the APy is recorded.
Step 9044, calculating a power difference between the transmitting power of the AP and the transmitting power reduction, and determining the power difference as the maximum transmitting power corresponding to the AP and required to meet the short-range wireless roaming condition.
Step 9045, notifying the maximum transmission power to the AP, so that the AP can adjust the transmission power down to be equal to or less than the maximum transmission power.
The above steps 9041 to 9045 are specific refinements of step 204 shown in fig. 2.
As can be seen from the method shown in fig. 9, in this embodiment, when it is determined that the AP does not meet the short-range wireless roaming condition according to the signal strength included in the surrounding AP information scanned by each AP in the roaming group, the maximum transmission power allowed by the AP and meeting the short-range wireless roaming condition is determined with reference to the correspondence between the pre-configured signal strength attenuation amount and the transmission power reduction amount, so that the transmission power of the AP is reduced to be equal to or less than the maximum transmission power, so that the signal strength between the AP and other APs in the roaming group is reduced to be able to meet the short-range wireless roaming condition, and therefore, the problem that wireless roaming between the STAs in the short-range APs cannot be triggered can be solved.
