Next, examples of the present application will be described in detail.
An embodiment of the present application provides an auxiliary access method, which is applied to any designated AP having multiple radio frequency units in a WLAN, where the multiple radio frequency units include a first radio frequency unit and a second radio frequency unit, and the first radio frequency unit and the second radio frequency unit both support a 5GHz frequency band and support different frequency bands, as shown in fig. 1, the method may include the following steps:
s11, monitoring the load parameters of the first radio frequency unit and the second radio frequency unit;
s12, when the Beacon message needs to be broadcast by the first radio frequency unit, if the monitored load parameter of the first radio frequency unit meets the first parameter threshold condition and the monitored load parameter of the second radio frequency unit does not meet the second parameter threshold condition, carrying the access guidance information of the specified information in the BSS information of the second radio frequency unit in the Beacon message, and broadcasting the access guidance information by the first radio frequency unit, so that the first wireless terminal receiving the Beacon message determines the radio frequency unit to be accessed and accesses the radio frequency unit at least according to the access guidance information carried in the received Beacon message carrying the access guidance information.
S13, when the Beacon message needs to be broadcast by the second radio frequency unit, if the monitored load parameter of the second radio frequency unit meets the second parameter threshold condition and the load parameter of the first radio frequency unit does not meet the first parameter threshold condition, carrying the access guidance information of the specified information in the BSS information of the first radio frequency unit in the Beacon message, and broadcasting the access guidance information by the second radio frequency unit, so that the second wireless terminal receiving the Beacon message determines the radio frequency unit to be accessed and accesses the radio frequency unit at least according to the access guidance information carried in the received Beacon message carrying the access guidance information.
It should be noted that, in the embodiment of the present application, the first radio frequency unit may be a radio frequency unit supporting a 5.2GHz band, and the second radio frequency unit may be a radio frequency unit supporting a 5.8GHz band; of course, the first radio frequency unit may also be a radio frequency unit supporting a 5.8GHz band, and the second radio frequency unit may also be a radio frequency unit supporting a 5.2GHz band.
Specifically, in step S11, for any one of the first radio unit and the second radio unit, the load parameter of the radio unit may be at least one of the number of wireless terminals accessing the radio unit, the channel utilization rate of the operating channel of the radio unit, and the total traffic generated by the wireless terminals accessing the radio unit. Of course, the load parameters of the rf unit may be other contents, which are not listed here.
Accordingly, in the embodiment of the present application, the preset corresponding parameter threshold conditions may be the same or different for the load parameters of the first radio frequency unit and the second radio frequency unit. That is, the first parameter threshold condition and the second parameter threshold condition in step S12 may be the same or different.
For example, the first parameter threshold condition may be that the number of wireless terminals accessing the first radio frequency unit is not less than a first number threshold (which may be set according to an actual situation of WLAN networking), and a difference between the number of wireless terminals accessing the first radio frequency unit and the number of wireless terminals accessing the second radio frequency unit is not less than a second threshold (which may be set according to an actual situation of WLAN networking), and the like; the second parameter threshold condition may be that the number of the wireless terminals accessing the second radio frequency unit is not less than the first number threshold, and the difference between the number of the wireless terminals accessing the second radio frequency unit and the number of the wireless terminals accessing the first radio frequency unit is not less than the second threshold, and the like.
It should be further noted that, in this embodiment of the present application, for any one of the first radio frequency unit and the second radio frequency unit, the designated AP periodically broadcasts the Beacon packet through the radio frequency unit, so that the wireless terminal accesses through a passive scanning manner. When the designated AP needs to broadcast the Beacon message through the radio frequency unit every time, whether the Beacon message carries the access guidance information or not can be decided according to the current load parameters of the radio frequency unit or the current load parameters of the two radio frequency units, so that the wireless terminal is assisted to be accessed to the radio frequency unit with low load in a passive scanning mode, and the user experience of a user holding the wireless terminal is improved.
Specifically, when the designated AP needs to broadcast the Beacon message through the first radio frequency unit, if the monitored load parameter of the first radio frequency unit does not satisfy the first parameter threshold condition, which indicates that the load of the first radio frequency unit is not high yet, the designated AP may carry access guidance information of the designated information in the BSS information including the first radio frequency unit in the Beacon message, and the designated information may include information such as BSSID of the first radio frequency unit, and broadcast the access guidance information through the first radio frequency unit, so that a third radio terminal receiving the Beacon message determines and accesses the radio frequency unit to be accessed at least according to the access guidance information carried in the received Beacon message carrying the access guidance information. Certainly, in this case, the designated AP may also broadcast the Beacon packet through the first radio frequency unit according to the existing manner, and the broadcast Beacon packet carries the BSS information of the first radio frequency unit. Subsequently, for a certain wireless terminal receiving the Beacon message, the radio frequency unit to be accessed may be determined and accessed according to the access guidance information carried in the received Beacon message carrying the access guidance information and the BSS information of the first radio frequency unit carried in the Beacon message not carrying the access guidance information.
If the monitored load parameter of the first radio frequency unit meets the first parameter threshold condition and the monitored load parameter of the second radio frequency unit does not meet the second parameter threshold condition, this indicates that the load of the first radio frequency unit is high, which is inconvenient for the wireless terminal to continue accessing, and the load of the second radio frequency unit is not high yet, which can bear the load of the wireless terminal to continue accessing, in this case, the designated AP may perform the step of "carrying the access guidance information including the designated information in the BSS information of the second radio frequency unit in the Beacon message, and broadcasting the access guidance information through the first radio frequency unit" in step S12. The specific information may include information such as BSSID of the first radio frequency unit.
If the monitored load parameter of the first radio frequency unit meets the first parameter threshold condition and the monitored load parameter of the second radio frequency unit meets the second parameter threshold condition, it indicates that the loads of the first radio frequency unit and the second radio frequency unit are both high, which is inconvenient for the wireless terminal to continue accessing.
When the designated AP needs to broadcast the Beacon message through the second radio frequency unit, if the monitored load parameter of the second radio frequency unit does not meet the second parameter threshold condition, the load of the second radio frequency unit is not high, and the wireless terminal can be born to continue accessing.
Certainly, in this case, the designated AP may also broadcast the Beacon packet through the second radio frequency unit according to the existing manner, and the broadcast Beacon packet carries BSS information of the second radio frequency unit. Subsequently, for a certain wireless terminal receiving the Beacon message, the radio frequency unit to be accessed may be determined and accessed according to the access guidance information carried in the received Beacon message carrying the access guidance information and the BSS information of the second radio frequency unit carried in the Beacon message not carrying the access guidance information.
If the monitored load parameter of the second radio frequency unit meets the second parameter threshold condition and the load parameter of the first radio frequency unit does not meet the first parameter threshold condition, this indicates that the load of the second radio frequency unit is already high, which is not convenient for the wireless terminal to continue accessing, and the load of the first radio frequency unit is not high yet, which can bear the wireless terminal to continue accessing, in this case, the designated AP may perform the step of "carrying the designated information in the BSS information including the first radio frequency unit in the Beacon message, and broadcasting the information through the second radio frequency unit" in step S13. The specific information may include information such as BSSID of the first radio frequency unit.
Further, in this embodiment, the plurality of radio frequency units may further include a third radio frequency unit supporting a 2.4GHz band. When the designated AP needs to broadcast the Beacon message through the third radio frequency unit, carrying access guidance information including designated information in BSS information of the radio frequency unit corresponding to the load parameters which do not meet the corresponding parameter threshold condition in the monitored load parameters of the first radio frequency unit and the second radio frequency unit in the Beacon message, wherein the designated information can include BSSID information and the like of the radio frequency unit corresponding to the load parameters which do not meet the corresponding parameter threshold condition in the monitored load parameters of the first radio frequency unit and the second radio frequency unit, and broadcasting the BSSID information through the third radio frequency unit so that a fifth wireless terminal receiving the Beacon message determines the radio frequency unit to be accessed and accesses the radio frequency unit at least according to the BSS information carried in all the received Beacon messages.
When the monitored load parameters of the first radio frequency unit and the second radio frequency unit of the designated AP meet the corresponding parameter threshold conditions, the designated AP indicates that the loads of the first radio frequency unit and the second radio frequency unit are higher and the wireless terminal is inconvenient to continue accessing.
It should be noted that, in this embodiment of the present application, for any one of the first wireless terminal, the second wireless terminal, the third wireless terminal, the fourth wireless terminal, and the fifth wireless terminal, all Beacon messages received by the wireless terminal may originate from different APs, and the APs may only include different designated APs; it may also include some designated APs and ordinary APs in the WLAN other than the designated AP, which broadcast Beacon messages in the existing manner.
Moreover, all Beacon messages received by the wireless terminal may be obtained after the wireless terminal has scanned all channels in its own channel list, or may be obtained after the wireless terminal has scanned part of channels in the channel list, which is related to the scanning mechanism of the wireless terminal.
When the radio frequency unit to be accessed is determined by the wireless terminal, the Beacon message carrying the access guidance information is identified firstly, and then the wireless terminal can directly determine the relevant information of the radio frequency unit to be accessed from the access guidance information carried in the Beacon message carrying the access guidance information based on a configured determination mechanism, such as a random selection mechanism; or based on a configured determination mechanism, determining the relevant information of the radio frequency unit to be accessed from the access guidance information carried in the Beacon message carrying the access guidance information and the BSS information carried in the Beacon message not carrying the access guidance information.
No matter which determination method is adopted by the wireless terminal to determine the radio frequency unit to be accessed, the probability that the determined radio frequency unit is a radio frequency unit with low load is greatly increased, and further the user experience of the holding user of the related wireless terminal is improved.
The above processes are processing processes when the designated AP needs to broadcast the Beacon message through each radio frequency unit, and are suitable for a scene that the wireless terminal accesses to the radio frequency unit of the designated AP in a passive scanning mode.
However, in the WLAN, some wireless terminals may access to the radio unit of the designated AP through an active scanning manner, and for this scenario, in the case that the designated AP only includes the first radio unit and the second radio unit, the designated AP may perform the following operations:
when the monitored load parameter of the first radio frequency unit meets a first parameter threshold condition and the monitored load parameter of the second radio frequency unit does not meet a second parameter threshold condition, if a Probe Request message broadcasted by a sixth wireless terminal is received through the first radio frequency unit, carrying access guidance information including specified information in BSS information of the second radio frequency unit in a Probe Response message, wherein the specified information can include information such as BSSID of the second radio frequency unit and the like, and sending the information to the sixth wireless terminal through the first radio frequency unit, so that the sixth wireless terminal determines and accesses the radio frequency unit to be accessed at least according to the access guidance information carried in the received Beacon message carrying the access guidance information;
when the monitored load parameter of the first radio frequency unit does not meet the first parameter threshold condition and the load parameter of the second radio frequency unit meets the second parameter threshold condition, if a Probe Request message broadcast by a seventh wireless terminal is received through the second radio frequency unit, access guidance information including designated information in BSS information of the first radio frequency unit is carried in the Probe Response message, wherein the designated information can include information such as BSSID of the first radio frequency unit and the like, and is sent to the seventh wireless terminal through the second radio frequency unit, so that the seventh wireless terminal determines and accesses the radio frequency unit to be accessed at least according to the received access guidance information carried in the Beacon message carrying the access guidance information.
Specifically, in this embodiment of the present application, when the monitored load parameter of the first radio frequency unit by the designated AP does not satisfy the first parameter threshold condition, it indicates that the load of the first radio frequency unit is not high, and the designated AP may bear a continuous access of the wireless terminal, and in this case, if the designated AP receives, through the first radio frequency unit, a Probe Request message broadcast by the eighth wireless terminal, the designated AP carries BSS information of the first radio frequency unit in the Probe Response message, where the designated information may include information such as BSSID of the first radio frequency unit, and sends the information to the eighth wireless terminal through the first radio frequency unit, so that the eighth wireless terminal determines and accesses the radio frequency unit to be accessed at least according to the access guidance information carried in the received Probe Response message carrying the access guidance information.
When the load parameter of the first radio frequency unit monitored by the designated AP meets the first parameter threshold condition and the load parameter of the second radio frequency unit does not meet the second parameter threshold condition, it indicates that the load of the first radio frequency unit is high, which is inconvenient for the wireless terminal to continue accessing, and the load of the second radio frequency unit is not high, which can bear the load of the wireless terminal to continue accessing. The specific information may include information such as BSSID of the second radio frequency unit.
When the load parameter of the first radio frequency unit monitored by the designated AP meets the first parameter threshold condition and the load parameter of the second radio frequency unit meets the second parameter threshold condition, it indicates that the loads of the first radio frequency unit and the second radio frequency unit are both high, which is inconvenient for the wireless terminal to continue accessing.
If the designated AP receives a Probe Request message broadcast by a ninth wireless terminal through the second radio frequency unit, the designated AP carries access guidance information including the designation information in the BSS information of the second radio frequency unit in the Probe Response message, where the designation information may include BSSID information of the second radio frequency unit and is sent to the ninth wireless terminal through the second radio frequency unit, so that the ninth wireless terminal determines and accesses the radio frequency unit to be accessed at least according to the access guidance information carried in the received Probe Response message carrying the access guidance information.
When the monitored load parameter of the first radio frequency unit does not meet the first parameter threshold condition and the load parameter of the second radio frequency unit meets the second parameter threshold condition, the designated AP indicates that the load of the second radio frequency unit is high, which is inconvenient for the wireless terminal to continue accessing, and the load of the first radio frequency unit is not high, which can bear the load of the wireless terminal to continue accessing. The specific information may include information such as BSSID of the first radio frequency unit,
when the load parameter of the first radio frequency unit monitored by the designated AP meets the first parameter threshold condition and the load parameter of the second radio frequency unit meets the second parameter threshold condition, it indicates that the loads of the first radio frequency unit and the second radio frequency unit are both high, which is inconvenient for the wireless terminal to continue accessing.
Further, in this embodiment of the present application, in a case that the designated AP includes a third radio frequency unit in addition to the first radio frequency unit and the second radio frequency unit, the designated AP may further perform the following operations:
when the designated AP receives a Probe Request message sent by the tenth wireless terminal through the third radio frequency unit, the access guidance information including the designated information in the BSS information of the radio frequency unit corresponding to the load parameter that does not satisfy the corresponding parameter threshold condition among the monitored load parameters of the first radio frequency unit and the second radio frequency unit is carried in the Probe Response message, where the designated information may include information such as BSSID of the radio frequency unit corresponding to the load parameter that does not satisfy the corresponding parameter threshold condition among the monitored load parameters of the first radio frequency unit and the second radio frequency unit, and is sent to the tenth wireless terminal through the third radio frequency unit, so that the tenth wireless terminal determines and accesses the radio frequency unit to be accessed at least according to the access guidance information carried in the received Probe Response message carrying the access guidance information.
Subsequently, when the designated AP receives a Probe Request message sent by a certain wireless terminal again through the third radio frequency unit, if the monitored load parameters of the first radio frequency unit and the second radio frequency unit both satisfy the corresponding parameter threshold conditions, it indicates that the loads of the first radio frequency unit and the second radio frequency unit are both high, and the wireless terminal is not convenient to continue accessing.
It should be noted that, in the embodiment of the present application, no matter which one of the above pieces of access guidance information is, a specific format may be as shown in table one below.
Wherein, Elemnet ID occupies 1 byte, for example, Element ID is 255;
length, which takes 1 byte, i.e., the total Length of the information Element, excluding the Element ID and the Length itself;
elements ID Extension, which occupies 1 byte, e.g., 200;
AP Identifier (id), occupying 2 bytes;
the Candidate Service number (Candidate Service Count) occupies 2 bytes, and for example, in a scenario where the load parameter of the first radio frequency unit of the AP satisfies the first parameter threshold condition and the load parameter of the second radio frequency unit of the AP does not satisfy the first parameter threshold condition, the Candidate Service number is 1;
the BSS handover Candidate List (BSS Transition List Entries of APs) accessing the AP occupies bytes as variables, and includes one or more Neighbor Report elements (Neighbor Report elements), and the content of each Neighbor Report Element may include specific information in the BSS information of a radio frequency unit on an AP, where the specific information may be key information required by some wireless terminals in the BSS information to access the radio frequency unit.
In addition, for any one of the sixth wireless terminal, the seventh wireless terminal, the eighth wireless terminal, the ninth wireless terminal, and the tenth wireless terminal, all Probe Response messages received by the wireless terminal may originate from different APs, and the APs may only include different designated APs; it may also include some designated APs and normal APs in the WLAN other than the designated AP, which send Probe Response messages in the existing manner.
Moreover, all the Probe Response messages received by the wireless terminal may be obtained after the wireless terminal has scanned all the channels in its own channel list, or may be obtained after the wireless terminal has scanned part of the channels in the channel list, which is related to the scanning mechanism of the wireless terminal.
When the radio frequency unit to be accessed is determined by the wireless terminal, the Beacon message carrying the access guidance information is identified firstly, and then the wireless terminal can directly determine the relevant information of the radio frequency unit to be accessed from the access guidance information carried in the Beacon message carrying the access guidance information based on a configured determination mechanism, such as a random selection mechanism; or based on a configured determination mechanism, determining the relevant information of the radio frequency unit to be accessed from the access guidance information carried in the Beacon message carrying the access guidance information and the BSS information carried in the Beacon message not carrying the access guidance information.
No matter which determination method is adopted by the wireless terminal to determine the radio frequency unit to be accessed, the probability that the determined radio frequency unit is a radio frequency unit with low load is greatly increased, and further the user experience of the holding user of the related wireless terminal is improved.
The above-mentioned auxiliary access method is described in detail with reference to specific embodiments.
Suppose that N APs are deployed in the WLAN, and all of the APs are designated APs, and each AP has a 2.4GHz band rf unit, a 5.2GHz band rf unit, and a 5.8GHz band rf unit. Wherein N is a positive integer.
Assuming that the load parameter of the radio frequency unit supporting the 5.2GHz frequency band is the number of wireless terminals accessing the radio frequency unit supporting the 5.2GHz frequency band, and the load parameter of the radio frequency unit supporting the 5.8GHz frequency band is the number of wireless terminals accessing the radio frequency unit supporting the 5.8GHz frequency band; the first parameter threshold condition set for the former is that the number of wireless terminals accessing the radio frequency unit supporting the 5.2GHz band is not less than a first number threshold, the difference between the number of wireless terminals accessing the radio frequency unit supporting the 5.2GHz band and the number of wireless terminals accessing the radio frequency unit supporting the 5.8GHz band is not less than a second threshold, and the second parameter threshold condition set for the latter is that the number of wireless terminals accessing the radio frequency unit supporting the 5.8GHz band is not less than the first number threshold, and the difference between the number of wireless terminals accessing the radio frequency unit supporting the 5.8GHz band and the number of wireless terminals accessing the radio frequency unit supporting the 5.2GHz band is not less than the second threshold.
For any one AP in the N APs, after the AP is powered on, the load parameters of the radio frequency unit supporting the 5.2GHz frequency band and the load parameters of the radio frequency unit supporting the 5.8GHz frequency band are monitored, and Beacon messages are broadcasted through each radio frequency unit according to a set period.
Assuming that a certain set period is reached, the AP needs to broadcast Beacon messages through each rf unit.
Specifically, when the AP needs to broadcast the Beacon message through the radio frequency unit supporting the 2.4GHz band, it is found that the monitored load parameter of the radio frequency unit supporting the 5.2GHz band satisfies the first parameter threshold condition and the load parameter of the radio frequency unit supporting the 5.8GHz band does not satisfy the second parameter threshold condition, and at this time, the access guidance information including the specific information in the BSS information of the radio frequency unit supporting the 5.8GHz band is carried in the Beacon message and broadcast through the radio frequency unit supporting the 2.4GHz band.
Subsequently, if the wireless terminal 1 receives the Beacon packet and scans all channels in a passive scanning manner, when the wireless terminal 1 selects a radio frequency unit to be accessed, the access guidance information carried in the Beacon packet carrying the access guidance information is used as a part or all of the selection basis, so that the probability that the wireless terminal 1 is accessed to the radio frequency unit with low load is increased, and the user experience of the user holding the wireless terminal 1 is improved.
When the AP needs to broadcast the Beacon message through the radio frequency unit supporting the 5.2GHz frequency band, the monitored load parameters of the radio frequency unit supporting the 5.2GHz frequency band are found to meet a first parameter threshold condition, and the load parameters of the radio frequency unit supporting the 5.8GHz frequency band are found not to meet a second parameter threshold condition, at the moment, the access guidance information including the designated information in the BSS information of the radio frequency unit supporting the 5.8GHz frequency band is carried in the Beacon message, and the Beacon message is broadcasted through the radio frequency unit supporting the 5.2GHz frequency band.
Subsequently, if the wireless terminal 2 receives the Beacon packet and scans all channels in a passive scanning manner, when the wireless terminal 2 selects a radio frequency unit to be accessed, the access guidance information carried in the Beacon packet carrying the access guidance information is used as a part or all of the selection basis, so that the probability that the wireless terminal 2 is accessed to the radio frequency unit with low load is increased, and the user experience of the user holding the wireless terminal 2 is improved.
When the AP needs to broadcast the Beacon message through the radio frequency unit supporting the 5.8GHz frequency band, the monitored load parameter of the radio frequency unit supporting the 5.8GHz frequency band is found not to meet the second parameter threshold condition, at the moment, the access guidance information including the specified information in the BSS information of the radio frequency unit supporting the 5.8GHz frequency band is carried in the Beacon message, and the access guidance information is broadcast through the radio frequency unit supporting the 5.2GHz frequency band.
Subsequently, if the wireless terminal 3 receives the Beacon packet and scans all channels in a passive scanning manner, when the wireless terminal 3 selects a radio frequency unit to be accessed, the access guidance information carried in the Beacon packet carrying the access guidance information is used as a part or all of the selection basis, so that the probability that the wireless terminal 3 is accessed to the radio frequency unit with low load is increased, and the user experience of the user holding the wireless terminal 3 is improved.
The specific processing flow when the AP needs to broadcast the Beacon message through each radio frequency unit when other periods arrive is already described in the above auxiliary access method, and no example is given here.
Assuming that the AP receives a Probe Request message broadcast by the wireless terminal 4 through the radio frequency unit supporting the 5.2GHz band under the condition that the monitored load parameter of the radio frequency unit supporting the 5.2GHz band satisfies the first parameter threshold condition and the monitored load parameter of the radio frequency unit supporting the 5.8GHz band does not satisfy the second parameter threshold condition, the AP carries access guidance information including specific information in BSS information of the radio frequency unit supporting the 5.8GHz band in the Probe Response message and sends the access guidance information to the wireless terminal 4 through the radio frequency unit supporting the 5.2GHz band.
After the wireless terminal 4 receives the Probe Response message and scans all channels in an active scanning manner, when the wireless terminal 4 selects a radio frequency unit to be accessed, the access guidance information carried in the Probe Response message carrying the access guidance information is used as a part or all of a selection basis, so that the probability that the wireless terminal 4 is accessed to the radio frequency unit with low load is increased, and the user experience of the user holding the wireless terminal 4 is further improved.
