Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
First, the embodiment of the present invention provides a kind of channel switching method.Below by way of specific embodiment to reality of the present invention
The channel switching method for applying example offer is described in detail.
As shown in figure 1, the channel switching method that the present embodiment is provided is comprised the following steps.
Step 11, when needing to carry out channel switching, the first via for supporting the access point of multiple-input and multiple-output MIMO is led to
Road keeps being connected with user equipment, and wherein, the access point of the support MIMO includes at least two paths, a-road-through road therein
For first paths.
Wherein, if needing to carry out channel switching can be determined by user, for example, when user is utilizing user equipment, with
When carrying out data interaction service between access point, if it is considered to current data interactive speed is slower, then can be cut by clicking on channel
The modes such as button are changed, embodies the intention for now needing to carry out channel switching.Certainly, above-mentioned with regard to needing to carry out channel switching
Only for the purposes of understanding, whether embodiment of the present invention not limited to this, for example, it is possible to be needed by user equipment automatic decision for citing
Channel switching is carried out, for example, if current channel rate is less than threshold value set in advance in user equipment, from trend access point
Message is sent, now needs to carry out the intention of channel switching to embody.
In addition, supporting that the access point of multiple-input and multiple-output MIMO supports multiple-input and multiple-output MIMO scheme, which has at least
Two inputs and at least two outputs, for example, such as three enter scene 2 MIMO, three enter three and go out MIMO etc..
In this case, as the access point for supporting multiple-input and multiple-output MIMO has at least two inputs and at least two
Output, therefore, it is possible to constitute the multiplexer channel of more than two-way, user equipment keeps being connected with a-road-through road therein.For example, such as
Shown in Figure 19, when access point supports two to enter scene 2 MIMO, it is respectively defined as being input into 1, input 2, output 1 and output 2, then
Input 1 may make up a-road-through road with output 1, and input 2 may make up another paths with output 2.In this case, the first of access point
Paths are input into 1 passage constituted with output 1, or the passage constituted by input 2 with output 2.
It is, of course, understood that above-mentioned is that two situations for entering scene 2 are only for example with regard to multiple-input and multiple-output MIMO, this
Invention not limited to this, for example, it is also possible to be three to enter scene 2 MIMO, now, as long as will any two and output 1,2 in input 1～3
Passage is constituted, and an input is now had as nothing output is matched and is in idle condition.
Step 12, determines switching channel from the passage of the access point of the support MIMO.
Wherein, due to needing channel switching is carried out, and support that the access point of MIMO may make up multichannel in itself, therefore will be from this
Passage is determined in the passage of access point.
As shown in Fig. 2 in a concrete application of the present invention, when the user equipment is for only supporting single-input single-output
During the user equipment of SISO, the step 12 comprises the following steps 121 and step 122.
Wherein, single-input single-output SISO is only one of which input and the scheme of an output, is supporting that single input list is defeated
Go out in the user equipment of SISO, a road can be only constituted for the passage for data interaction.
Step 121, the channel switching life of user equipment described in the first via channel reception of the access point of the support MIMO
Order, and the channel switching command is sent to arbitrary paths of the access point of the support MIMO, wherein described support
The frequency of arbitrary paths of the access point of MIMO is different from the frequency of the first paths of the access point of the support MIMO.
Wherein, when transfer rate is slower, user equipment itself can send manually or automatically channel switching life by user
Order.The a certain paths of access point receive the channel switching command so as to become the passage being connected to different from user equipment
Frequency, for example, the frequency of the current passage of connection of user equipment is 2.4GHz, then sent the passage of channel switching command not
Adopt 2.4GHz again, but use other frequencies.
Step 122, after the confirmation message for receiving arbitrary paths of access point of the support MIMO, by described
Arbitrary paths of access point of MIMO are held as the switching channel.
In this step, receive after the confirmation message of arbitrary paths of access point in user equipment, that is, represent
The paths can be used to carry out channel switching, therefore, now arbitrary paths of the access point is regarded as switching channel.
As shown in figure 3, in one of the present invention more specifically embodiment, when the user equipment is for only supporting single input
During the user equipment of single output SISO, step 12 also includes：
Step 123, the first paths of the access point of the support MIMO forward the switching logical to the user equipment
The completed channel handoff completion message in road.
Specifically, after arbitrary paths, the i.e. switching channel in the access point of support MIMO completes channel switching,
Can would indicate that switching channel this message completed is sent to user and sets by the first paths for being connected to user equipment
Standby.
After completing the procedure, in step 13, by the company of the access point of the support MIMO and the user equipment
Connect and be switched on the switching channel.
As shown in figure 4, specifically, the step 13 may include following steps 131 and 132.
Step 131, by the first paths of the access point of the support MIMO, the user equipment is logical with the switching
Pre-authentication is carried out between road.
Here, carry out pre-authentication to refer between user equipment and switching channel, user equipment and the passage that will switch
Between predictive authentication, thus can shorten switching time for being used of channel further.
Step 132, after the pre-authentication is completed, by the connection of the access point of the support MIMO and the user equipment
It is switched on the switching channel.
Now, recognized due to completing via the first paths between user equipment and the switching channel of access point in advance
Therefore the connection of the user equipment directly can be switched to switching channel by card.
In a particular application, as shown in figure 5, following steps 133 can be increased after the pre-authentication is completed.
Step 133, cuts off the first paths and the user equipment of the access point of the support multiple-input and multiple-output MIMO
Connection.
This is because, because user equipment is for supporting single-input single-output SISO, the two of access point therefore can not be simultaneously connected with
Road and its above passage, therefore when user equipment is connected with switching channel, it is necessary first to switching and first for being currently connected
Connection between paths.
Channel switching method provided in an embodiment of the present invention, by by the access point of support multiple input multiple output scheme
Multi-input multi-ouput channel is divided into the single-input single-output channel of multichannel such that it is able to by an at least road single-input single-output
Channel maintains the connection between user equipment and access point, and carries out letter using other the single-input single-output channels in access point
Road switches, thus, although carry out disconnecting with user equipment when channel switches in other single-input single-output channels, Yong Hushe
Standby still can maintenance using an above-mentioned at least road single-input single-output channel with access point is communicated, so as to avoid middle prior art
Present in channel switching spend overlong time problem, improve user experience.
Below with a specific embodiment, it is only to support that the situation of the user equipment of SISO is illustrated to user equipment.
As shown in figure 20, single-input single-output SISO only supported by user equipment, with by an input and an output structure
The SISO passage for becoming.In the present embodiment, the user equipment is the user equipment with a road SISO passage.In addition, access point
For supporting multiple-input and multiple-output MIMO, specifically, which has dual input and output 1 and the output 2 of input 1 and input 2
Dual output.In embodiments of the present invention, multiple-input and multiple-output MIMO is divided into multichannel single input and multi-output by the access point
SISO.Specifically, as illustrated, making input 1 constitute the first paths SISO1 with output 1, and input 2 is made to constitute with output 2
Second paths SISO2.
In the present embodiment, the input of user equipment and a certain road SISO passage of access point and output be connecteds, in figure, use
Family equipment is connected with the first paths SISO1 of access point.Transfer rate between user equipment and access point preferably feelings
Under condition, the interaction of data is can achieve by first paths SISO1.
When being interfered due to channel, when causing channel circumstance to be deteriorated, the transfer rate between user equipment and access point
Can be deteriorated.
In this case, user can click on the channel switching key on user equipment, make the channel switching command via
The output of user equipment, the input of the SISO1 of access point are sent to the first paths SISO1 of access point.
First paths SISO1 by intercommunication, forwards it to the access after the channel switching command is received
The second paths SISO2 in point.The second paths SISO2 is carried out channel and cuts after the channel switching command is received
Change, make the frequency after switching be different from the frequency of the first paths.For example, the frequency in the first paths SISO1 is 2.4GHz
In the case of, the frequency of the channel of the second paths SISO2 can switch to the frequency of 2.4835GHz.It is understood that should
Frequency error factor mode is illustrated only for the purposes of understanding, it is possible to use alternate manner carries out frequency error factor.For example, user is according to certainly
Oneself needs arrange frequency scanning interval, and save it in the configuration file of user equipment, with when channel switches, should
Information is sent to access point so as to which the frequency scanning that pre-sets according to user interval is scanning channel, and switches to scanning and obtain
On the channel for obtaining.
After the completion of the channel switching of second paths SISO2, by intercommunication, by disappearing that its channel switching is completed
Breath is sent to the first paths SISO1.This is believed by the first paths SISO1 by the communication between the SISO of user equipment
The message that road switching is completed is transmitted to the user equipment.
The user equipment after the message that channel switching is completed is received, by the first paths SISO1 to access point
Send pre-authentication request.First paths SISO1 after the pre-authentication request is received, by intercommunication, by the pre-authentication
Request is transmitted to the second paths SISO2.Thus, via the first paths SISO1, user equipment and the second paths are completed
Pre-authentication between SISO2.
After above-mentioned pre-authentication is completed, user equipment sends cut-out request to the first paths SISO1 of access point, with disconnected
Open connection therebetween.Association request is sent immediately to the second paths SISO2, with the second paths for having switched channel
SISO2 is attached.
As shown in figure 21, the second paths SISO2 of access point is received after the association request of user equipment, is accessed
Second paths SISO2 of point can be set up with the passage SISO of user equipment and be connected.
In the present embodiment, after user equipment is connected with the second paths SISO2 of access point, in order to confirm the connection
Whether speed afterwards meets user's request, employs following manner.
User sets rate threshold value first according to theoretical transmission rate and real work demand rate, and by the speed
Threshold value is stored in the middle of the configuration file of user equipment.After user equipment is connected with the second paths SISO2 of access point,
Judge whether current transfer rate meets the rate threshold value preserved in configuration file.Speed is met in current transfer rate
In the case of rate threshold value, that is, the speed after thinking to connect meets user's request.
Conversely, in the case that current transfer rate is unsatisfactory for rate threshold value, it is believed that the speed after connection is unsatisfactory for
User's request, in this case, user equipment keeps being connected with the second paths SISO2 of access point, and logical by second tunnel
Road SISO2, sends channel switching command in intercommunicating mode to the first paths SISO1 of access point.First paths
SISO1 carries out channel switching after the channel switching command is received, and makes the frequency after switching be different from the frequency of the first paths
Rate.Thus, it is possible to repeat channel switching between the two paths of access point, until transfer rate meets rate threshold value
Till.
It is, of course, understood that confirming whether the speed after the connection meets the mode of user's request and be not limited only to
Mode is stated, for example, whole working band can also be scanned, in the scanning process to whole working band, user equipment
A configuration file can be safeguarded always, all be tested the speed when being connected to a new operating frequency every time, and in the configuration file
Middle preservation connection speed and its corresponding operating frequency.If after whole working band is scanned through, fail to find speed and be more than
The frequency of rate threshold value, then the channel of the frequency corresponding with maximum connection speed for selecting the configuration file to be preserved, with
Ensure that transfer rate now is currently most fast in all channels.
In another case, user equipment can be the user for supporting multiple-input and multiple-output MIMO as access point
Equipment.As shown in fig. 6, when the user equipment is the user equipment for supporting MIMO, the step 11 is specially as follows.
Step 111, will support that the first paths of the access point of MIMO are kept with the first paths of the user equipment
Connection.
In this case, as multiple-input and multiple-output MIMO all supported by access point and user equipment, therefore can respectively constitute
Passage more than two-way, now, can will hold the first paths of the access point of MIMO and the first paths of the user equipment
Keep connection.
Also include step 112 in the method, by support multiple-input and multiple-output MIMO access point the second paths with
The second paths connection of user equipment.
In the case that user equipment and access point are respectively provided with multiplexer channel, other passages in addition to the first paths that
This is connected.
In a particular application, as shown in fig. 7, step 12 may include step 121 '.
Step 121 ', the second paths of the access point of the support MIMO are defined as the switching channel.
That is, second paths being connected with the second paths of user equipment of access point are by as switching channel.
In this case, as shown in figure 8, with above-mentioned steps accordingly, the step 13 specifically includes following steps.
Step 131 ', the switching channel receives the channel switch request of the second paths of the user equipment.
Now, as the switching channel is in connection status with user equipment, therefore can directly receive and set from the user
Standby channel switch request.
Step 132 ', the second paths and the institute of the access point of the support MIMO is cut off according to the channel switch request
State the connection of the second paths of user equipment.
After the channel switch request is connected to, being cut with the connection of user equipment of the second paths of the access point
Disconnected, now, the second paths of access point carry out channel switching.
Step 133 ', logical by the second tunnel of the second paths of the access point of the support MIMO, the user equipment
Road, the access point of the support MIMO is switched on the switching channel with the connection of the user equipment.
Specifically, by the first paths of the access point of support MIMO, the channel of the second paths can be switched
Message is sent to user equipment, also can be again coupled to request to access point transmission so as to the second paths of user equipment, so as to
To support that the access point of MIMO is switched on the switching channel with the connection of user equipment.
In one particular embodiment of the present invention, as shown in figure 9, the step 133 ' comprise the steps.
Step 1331 ', the switching channel receives the connection request of the user equipment.
Specifically, first paths that the switching channel can be connected with its access point via user equipment etc. are received should
The connection request of user equipment.
Step 1332 ', the switching channel is by the second paths of the access point of the support MIMO to the user
