Detailed Description
In order to realize seamless switching of the WiFi networks, in the embodiment of the invention, the terminal periodically detects the signal intensity of each WiFi network deployed in the peripheral range, and if the current connected WiFi network is in a poor state and meets the switching condition, the WiFi network in the best working state is switched to without influencing the current operation experience of a user.
Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, in the embodiment of the present invention, a terminal may pass through signal coverage areas of a plurality of WiFi hotspots in a moving process, and the terminal may scan WiFi networks in a peripheral area all the time in a background and store IDs of the WiFi networks, and if a user accesses some WiFi networks, the terminal may record identification information (e.g., an ID) of the WiFi networks and corresponding access passwords, and further, since WiFi networks arranged in public places (e.g., large shopping malls, airports) may not need to input an access password, the terminal only records IDs of WiFi networks after accessing such WiFi networks.
Referring to fig. 2, in the embodiment of the present invention, a detailed procedure for a terminal to perform handover between WiFi networks is as follows:
step 200: the terminal accesses a first WiFi network.
Specifically, after the user turns on the WiFi function of the terminal, the terminal will automatically connect to the nearby WiFi network with the strongest signal strength.
Step 210: the terminal scans the WiFi network with the use authority within a preset range, and records the scanning result as a WiFi network set to be switched. Will be provided with
Specifically, the terminal records, as a set of WiFi networks to be switched, WiFi networks meeting a preset condition and scanned within a preset range, where the WiFi networks meeting the preset condition (i.e., WiFi networks for which the terminal has a use right) include at least the following:
the first method comprises the following steps: the terminal has accessed and saved the WiFi network of the access password.
And the second method comprises the following steps: the terminal has ever accessed and does not need to use the WiFi network of the access password.
And the third is that: a WiFi network that the terminal has not accessed but does not need to use an access password.
Specifically, the terminal stores the set of WiFi networks to be switched in a list form, and optionally, the list at least includes an ID, an access password, and a signal strength of the WiFi network that the terminal has permission to use.
Further, the terminal may also record the following contents in the set of WiFi networks to be switched:
and fourthly: the terminal has not accessed and needs a WiFi network using an access password.
Step 220: and the terminal calculates a corresponding network state evaluation value aiming at each WiFi network in the WiFi network set to be switched.
Specifically, the terminal traverses each WiFi network in the list, and calculates a network status evaluation value for each WiF network, wherein,
specifically, the network state evaluation value of a WiFi network is positively correlated with the signal strength of the WiFi network, and is negatively correlated with the network delay and the network anomaly number of the WiFi network.
For example, optionally, taking one WiFi network x in the list as an example, the following steps may be adopted but not limited when calculating the corresponding network state evaluation value x.
Step A: the terminal detects the signal intensity of the WiFi network x and records the signal intensity as A, the greater the value of A is, the better the reliability of the representation WiFi network x is, and correspondingly, the higher the network state evaluation value is.
And B: the terminal detects the network delay of the WiFi network x and records the network delay as B, the larger the value of B is, the worse the reliability of the representation WiFi network x is, and correspondingly, the lower the network state evaluation value is.
Specifically, the terminal may send an Internet Control Protocol (ICMP) echo request Message to the WiFi hotspot x by using a ping command based on an IP address of the WiFi hotspot x in the WiFi network x, and receive a corresponding ICMP echo response Message, and by this means, the terminal may test connectivity between the local and the WiFi hotspot x, and may calculate the network delay of the WiFi network x based on a sending time of the ICMP echo request Message and a receiving time of the ICMP echo response Message.
For example, the message format of the ICMP echo reply message is as follows:
reply from 61.135.169.121: byte 32 time 19ms TTL 52
Reply from 61.135.169.121: byte-32 time-17 ms TTL-52
Reply from 61.135.169.121: byte 32 time 19ms TTL 52
Reply from 61.135.169.121: byte-32 time-20 ms TTL-52
Generally, 4 ICMP echo response messages are sent, and the calculated average network delay is denoted as B.
And C: the terminal detects the network abnormal times of the WiFi network x, the network abnormal times are recorded as C, the larger the value of C is, the worse the reliability of the representation WiFi network x is, and correspondingly, the lower the network state evaluation value is.
Specifically, when the working state of the current WiFi network x changes, it is optional that the WiFi hotspot x is present
The method includes the steps that a broadcast mode is adopted, a first notification message is sent in a system, for example, WIFI _ STATE _ CHANGED _ ACTION, a terminal receives the first notification message regularly, and can acquire the current connection STATE of a WIFI network x according to a field int WIFI STATE (int ext, 0), if the connection STATE is not connectable (i.e., enabled), the connection STATE of the WIFI network x is indicated to be in a problem, the terminal sets the WIFI network x to be ErrorCount, exception counting is carried out, and the network exception times of the WIFI network x can be acquired according to a counting result.
Step D: the terminal calculates a network state evaluation value of the WiFi network based on the signal intensity, the network time delay and the network abnormal frequency of the WiFi network, wherein the network state evaluation value is positively correlated with the signal intensity and negatively correlated with the network time delay and the network abnormal frequency.
Optionally, the terminal may adopt a formulaCalculating the network state evaluation value of the WiFi network x, wherein the evaluation value can be different according to different application environmentsTo add different coefficients for A, B and C, which are not described in detail herein.
The bigger the value of P is, the better the signal intensity, the lower the network delay and the less the network abnormal times of the WiFi network x are proved.
Step 230: when the terminal judges whether the network state evaluation value of the first WiFi network currently accessed meets the use requirement, if yes, returning to step 210; otherwise, step 240 is performed.
Further, for the currently accessed first WiFi network, the terminal also needs to calculate a corresponding network state evaluation value by using the above method, and then when determining whether the network state evaluation value of the currently accessed first WiFi network meets the use requirement, the terminal may use, but is not limited to, the following two methods:
the first method comprises the following steps: and the terminal compares the network state evaluation value of the first WiFi network with the network state evaluation values of all the WiFi networks in the to-be-switched WiFi network set, and determines that the working state of the first WiFi network does not meet the use requirement when the network state evaluation value of the first WiFi network is judged not to be the highest value.
In this case, as long as the terminal perceives that the first WiFi network is not the WiFi network with the best working state in the peripheral range, it may be determined that the network state evaluation value of the first WiFi network does not meet the usage requirement, thereby triggering the subsequent handover procedure. Therefore, in a scene that the terminal frequently moves, the terminal can be always accessed to the WiFi network with the best current working state, so that the network smoothness of the application service used by the terminal is ensured, and the service performance is further ensured.
The second method is as follows: and when the terminal judges that the network state evaluation value of the first WiFi network is lower than a set switching threshold value, determining that the working state of the first WiFi network does not meet the use requirement.
In this case, when the terminal perceives that the first WiFi network is not the WiFi network with the best working state in the peripheral range, the terminal does not immediately trigger the subsequent handover procedure, but further determines that the network state evaluation value of the first WiFi network is lower than the set handover threshold value, and then determines that the network state evaluation value of the first WiFi network does not meet the use requirement, so as to trigger the subsequent handover procedure, where the handover threshold value is not a threshold value representing that the first WiFi network has a network abnormality, but may be a threshold value representing that the first WiFi network is in an intermediate state, for example, 50% of a highest value of the network state evaluation value. Therefore, in the scene of infrequent movement of the terminal, frequent switching of the terminal can be avoided, so that the network stability of the application service used by the terminal is ensured, and the service performance is further ensured.
On the other hand, the switching threshold may be set by advance notice by a manager in a preprocessing stage according to management experience, or may be set in real time by a terminal after comprehensive evaluation is performed according to the current network state evaluation value of the first WiFi network and the current network state evaluation values of other WiFi networks within a preset range, which is not described herein again.
Step 240: and the terminal selects a WiFi network with the network state evaluation value not lower than a set switching threshold value from the to-be-switched WiFi network set as a second WiFi network based on the obtained network state evaluation value.
Optionally, in the step 240, the terminal may adopt, but is not limited to, the following two methods:
the first method comprises the following steps: and the terminal screens out all WiFi networks with the network state evaluation values not lower than a set switching threshold value from the WiFi network set to be switched, and selects the WiFi network with the highest network state evaluation value from the screened WiFi networks to serve as a second WiFi network.
The second method comprises the following steps: and the terminal screens out all WiFi networks of which the network state evaluation value is not lower than a set switching threshold value from the WiFi network set to be switched, and randomly selects one WiFi network from the screened WiFi networks to serve as a second WiFi network.
Step 250: and the terminal is switched from the first WiFi network to the second WiFi network.
Specifically, when the terminal determines that the working state of the terminal meets a preset switching condition, the terminal is switched from the first WiFi network to the second WiFi network.
The switching of the WiFi network inevitably causes a temporary interruption between the terminal and the internet, in order to not affect user experience, the terminal needs to compress the interruption time to the shortest as possible, that is, to implement seamless switching to the maximum extent, then the terminal selects switching as much as possible when the terminal is inactive so as to reduce the perception of the user to switching, and therefore the terminal needs to select a switching opportunity based on the preset switching condition, and the specific preset switching condition includes but is not limited to the following:
the first method comprises the following steps: the terminal determines that it is in a standby state or the generated network traffic is 0.
When the terminal is in a standby state or the generated network flow is 0, it indicates that the user does not use the terminal to surf the internet currently, so that the user experience is not influenced by the WiFi network switching.
Specifically, the system transmits a broadcast message of android. intent. action. SCREEN _ OFF when the terminal is in the standby state, and thus, when the terminal determines that it has transmitted the broadcast message, it determines that it is in the standby state inactive.
And the second method comprises the following steps: and the terminal judges that the network flow generated by the terminal is lower than a set flow threshold value.
For example, when a user is using the terminal to surf the internet, the terminal monitors the current real-time network traffic, and if the monitoring result indicates that the uploading network traffic or/and the downloading network traffic at the moment tend to 0, it indicates that the WiFi network at the current moment is stuck, and then the WiFi network switching at the moment does not affect the user experience.
And the third is that: the terminal judges that the network flow generated by the terminal reaches a set flow threshold value, but the fluctuation range of the network flow is higher than a preset range threshold value.
In practical application, when a user uses a terminal to surf the internet, the terminal is in an active state, and in principle, in order not to affect the user experience, WiFi network switching should not be performed at this time, but if the terminal is in an edge zone of a currently accessed WiFi network, the signal strength at this time can only support the user to surf the internet, network traffic generated by the terminal fluctuates to a greater extent, and the fluctuation of the network traffic affects the user experience.
Further, referring to fig. 3, in the embodiment of the present invention, in a process of switching a terminal from a first WiFi network to a second WiFi network, the terminal specifically executes the following steps:
first, the terminal requests access to the second WiFi network.
Secondly, the terminal disconnects with the first WiFi network;
and thirdly, the terminal passes the authentication of the second WiFi network.
In the authentication process, the terminal can adopt two types of authentication modes defined based on the IEEE802.11 standard: open system (OpenSystem) authentication and Shared Key (Shared Key) authentication.
Take shared key authentication as an example.
If the terminal accesses the second WiFi network, the terminal can automatically input the access password of the second WiFi network according to the locally recorded related information so as to pass the authentication process of the second WiFi network.
And if the terminal never accesses the second WiFi network, the terminal prompts the user to input an access password and passes through the authentication process of the second WiFi network according to the access password input by the user.
And finally, the terminal is re-associated to a second WiFi network, the second WiFi network is triggered to acquire a cache data frame which is not transmitted aiming at the terminal from the first WiFi network, namely, the cache data frame is formally accessed to the second WiFi network, the complete access right of the second WiFi network is acquired, and data transmission is started.
A specific application scenario is taken as an example for explanation, it is assumed that a user deploys a hotspot 1 in a home 1, the optimal coverage area of a WiFi signal is floor 1, meanwhile, the user deploys a hotspot 2 in a home 2, and the optimal coverage area of the WiFi signal is floor 2, when the terminal accesses for the first time, the terminal stores WiFi IDs and access passwords of the hotspot 1 and the hotspot 2 locally, and then, when the user carries the terminal at home, the terminal does not need to be manually operated by the user, and can automatically switch between the hotspot 1 and the hotspot 2 when the user moves to and from the floor 1 and the floor 2, so that the user can access the internet through the hotspot with the best working state at any time, and the service performance of the application service of the user is ensured.
