In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic implementation flow diagram of a handover method of a wireless network according to an embodiment of the present application, and as shown in the figure, the method may include the following steps:
step S101, acquiring a network state of a first wireless network, wherein the first wireless network is a wireless network to which the mobile terminal is currently connected.
In this embodiment of the application, the first wireless network is a wireless network to which the mobile terminal is currently connected, and the wireless network may be an internet access mode provided by no connection of a wired line, for example, a wireless local area network, a GPRS mobile phone, and the like. Taking a Wireless local area network as an example, when a mobile terminal is successfully connected to a Wireless network, the mobile terminal is accessed to any one Wireless Access Point (AP), and the AP is also referred to as a Wireless hotspot. Since wireless networks have a certain coverage, a mobile terminal may be successfully connected to the wireless network within the coverage of the wireless network, and when the mobile terminal is not within the coverage of the wireless network, the mobile terminal may not be successfully connected to the wireless network due to weak signal strength.
The method includes that after the mobile terminal is successfully connected to the wireless network, the network state of the first wireless network which is currently connected is acquired, the network state of the first wireless network which is currently connected can be acquired once after the mobile terminal is successfully connected to the wireless network, and the network state of the first wireless network which is currently connected can be acquired at a preset time interval after the mobile terminal is successfully connected to the wireless network.
The network state of the wireless network includes: the wireless network can provide internet access service for the mobile terminal connected with the wireless network if the network state of the wireless network is internet access available; if the network state of the wireless network is that the wireless network cannot surf the internet, the wireless network cannot provide internet surfing service for the mobile terminal connected with the wireless network. In a specific application, the network state of the currently connected first wireless network may also be determined by obtaining the network speed of the currently connected first wireless network, which is not limited herein.
For example, if the network speed of the currently connected first wireless network is greater than or equal to the speed threshold, it is determined that the network state of the currently connected first wireless network is internet-enabled;
and if the network speed of the first wireless network connected currently is less than the speed threshold, determining that the network state of the first wireless network connected currently is internet-surfing incapable.
Step S102, if the network state of the first wireless network is that the network cannot be accessed, scanning a second wireless network, and taking the scanned second wireless network associated with the first wireless network as a candidate wireless network, wherein the second wireless network is a wireless network except the first wireless network.
In the embodiment of the present application, the mobile terminal may be capable of scanning multiple wireless networks at the same time in one geographic location, for example, simultaneously scanning wireless hotspot a, wireless hotspot B, wireless hotspot C, and the like. Although the mobile terminal may scan multiple wireless hotspots at the same time in one geographic location, the mobile terminal is not switched to any one of the scanned second wireless networks at any time, and when the network state of the currently connected first wireless network is that internet access cannot be performed, that is, the currently connected first wireless network cannot provide internet access service for the mobile terminal, switching to the second wireless network may be considered, and the second wireless network needs to be scanned at this time, where the second wireless network is a wireless network other than the currently connected first wireless network. The second wireless network associated with the first wireless network is prioritized in considering handover to the second wireless network.
The second wireless network associated with the first wireless network may be a second wireless network associated with the first wireless network that is preset by the user, for example, the wireless network a to which the mobile terminal is currently connected, the first wireless network is wireless network a, the wireless network to which the user has preset wireless network a is wireless network B, wireless network C, wireless network G, and the like, and the currently scanned wireless networks include: wireless network A, wireless network B, wireless network C, wireless network D and wireless network E. The second wireless network is: wireless network A, wireless network B, wireless network C, wireless network D and wireless network E. Then, the second wireless network associated with the first wireless network scanned is: wireless network B, wireless network C. Wireless network B, wireless network C may be considered candidate wireless networks. It can be seen that the conditions of the candidate wireless network are: is currently capable of being scanned for and associated with a currently connected first wireless network.
The second wireless network associated with the first wireless network may be further configured to: the wireless network which has been historically connected to the mobile terminal to be a failed wireless network, or the wireless network which has been historically connected successfully and successfully surfs the internet can be used as the second wireless network associated with the wireless network A. Of course, the conditions of the candidate wireless networks are still: is currently capable of being scanned for and associated with a currently connected first wireless network.
In practical applications, the second wireless network associated with the first wireless network may also be configured in other manners, for example, the second wireless network associated with the first wireless network is preset to be a wireless network capable of implementing seamless roaming, and for the seamless roaming, reference may be specifically made to the example in the embodiment shown in fig. 2.
Step S103, determining whether the signal intensity value existing in the candidate wireless networks is larger than a first preset value, and determining whether the wireless networks meet preset conditions with the historical connection records of the mobile terminal.
In this embodiment of the present application, a change in a distance between a mobile terminal and a transmitting end of a wireless access point may cause a change in a Signal Strength value (RSSI) of a wireless network to which the mobile terminal is connected, where the RSSI is represented by the Signal Strength value.
It should be noted that the signal strength value does not refer to a signal strength value of a wireless network transmitting end, but refers to a signal strength value of the wireless network received by the mobile terminal, and a change in a distance between the mobile terminal and a currently connected wireless network may cause a change in a signal strength value of the wireless network received by the mobile terminal.
The reason for determining whether the wireless network with the signal strength value larger than the first preset value exists in the candidate wireless networks is that the wireless network can possibly establish connection with the mobile terminal only under the condition that the signal strength value of the wireless network is larger than a certain value, and the wireless network can provide stable internet access service for the mobile terminal.
Whether a wireless network which meets the preset conditions with the historical connection record of the mobile terminal exists in the candidate wireless networks is determined so as to further screen out a wireless network which can provide stable internet access service from the historical connection record.
As another embodiment of the present application, the determining whether there is a wireless network in the candidate wireless networks, where a signal strength value is greater than a first preset value, and a historical connection record with the mobile terminal meets a preset condition includes:
and determining whether a wireless network with a signal strength value larger than a first preset value and a historical connection frequency of 0 with the mobile terminal exists in the candidate wireless networks.
In this embodiment of the application, the preset condition is related to a historical connection record, the historical connection record is a historical connection record between the mobile terminal and the candidate wireless network, and a wireless network whose historical connection frequency with the mobile terminal is 0 may also be understood as whether the historical record of the mobile terminal initiating the connection request to the candidate wireless network is 0, and if the historical record of the mobile terminal initiating the connection request to the candidate wireless network is 0, it indicates that the candidate wireless network is not a wireless network to which the mobile terminal has been historically connected, that is, the mobile terminal may be able to successfully connect to the candidate wireless network and successfully surf the internet through the candidate wireless network.
As another embodiment of the present application, the determining whether there is a wireless network in the candidate wireless networks, where a signal strength value is greater than a first preset value, and a historical connection record with the mobile terminal meets a preset condition includes:
and determining whether a wireless network exists in the candidate wireless networks, wherein the signal intensity value is greater than a first preset value, the historical connection times with the mobile terminal are not 0, and the network state is a wireless network capable of surfing the internet in the historical connection process with the mobile terminal.
In this embodiment of the application, if the number of times of historical connection with the mobile terminal is not 0, indicating that the candidate wireless network is a wireless network that the mobile terminal has historically connected to, indicating that the mobile terminal is also likely to be successfully connected to the candidate wireless network at present, it is necessary to further confirm a network state of the candidate wireless network in the process of historical connection between the mobile terminal and the candidate wireless network, and if the network state is internet-enabled, indicating that the candidate wireless network meets a preset condition, and if the network state is internet-disabled, even if the connection is successful, a problem of internet-disabled may occur, so indicating that the candidate wireless network does not meet the preset condition.
And step S104, if the signal intensity value of the candidate wireless network is greater than a first preset value and the wireless network with the historical connection record of the mobile terminal meeting the preset conditions exists, taking the wireless network as a target wireless network and controlling the mobile terminal to be switched from the first wireless network to the target wireless network.
In the embodiment of the present application, if there exists a wireless network in the candidate wireless networks, where the signal strength value is greater than the first preset value and the historical connection record of the mobile terminal meets the preset condition, the candidate wireless network, where the signal strength value is greater than the first preset value and the historical connection record of the mobile terminal meets the preset condition, may be taken as the target wireless network. The second wireless network associated with the first wireless network is a wireless network that can ensure free handoff between the first wireless network and the second wireless network, and can log in without authentication.
It can be seen from the above description that, a part of wireless networks which may be successfully connected and may provide internet access service after successful connection are screened out from the scanned wireless networks as candidate wireless networks, then a part of wireless networks which have a higher probability of successful connection and a higher probability of providing stable internet access service after successful connection are further screened out from the candidate wireless networks as target wireless networks, and finally the mobile terminal is controlled to be switched from the currently connected wireless network to the target wireless network.
Fig. 2 is a flowchart illustrating another handover method for a wireless network according to an embodiment of the present application, where as shown in the figure, the method may include the following steps:
step S201, a network state of a first wireless network is obtained, where the first wireless network is a wireless network to which the mobile terminal is currently connected.
In this embodiment of the present application, the acquiring a network status of a first wireless network includes:
accessing a preset server through the first wireless network, and acquiring an access result;
if the access result is successful, confirming that the network state of the first wireless network is internet-enabled;
and if the access result is access failure, determining that the network state of the first wireless network is internet-unavailable.
In the embodiment of the present application, not only the network status of the first wireless network may be obtained in the manner shown in the embodiment shown in fig. 1, but also the preset server may be accessed through the first wireless network, and the network status of the first wireless network is confirmed according to the access result, for example, a preset website is accessed through the first wireless network, and the access result of this time is obtained.
Step S202, if the network status of the first wireless network is internet-enabled, acquiring a signal strength value of the first wireless network.
In the embodiment of the present application, different from the embodiment shown in fig. 1, when a first wireless network currently connected in the embodiment shown in fig. 1 cannot provide an internet access service, it needs to switch to another wireless network meeting requirements, that is, a second wireless network meeting the requirements. In the embodiment of the application, when the currently connected first wireless network can provide the internet access service, however, the signal of the currently connected first wireless network is too weak, and there is a problem that the internet access is unstable, that is, the access result of successful access is returned by accessing the preset server, however, the result of failed access may occur when accessing other servers. Therefore, it is further required to determine whether the signal strength value of the currently connected first wireless network is smaller than the second preset value. If the signal intensity value of the currently connected first wireless network is smaller than a second preset value, switching to other second wireless networks meeting the requirements can be considered.
Step S203, if the signal strength value of the first wireless network is smaller than a second preset value, scanning a second wireless network, and using the scanned second wireless network associated with the first wireless network as a candidate wireless network.
In the embodiment of the present application, a second wireless network associated with a currently connected first wireless network may also be set, for example, in the setting of seamless roaming of multiple Wifi wireless routers, when an office area of a company is large, a wireless network provided by one wireless router cannot cover the whole office area, at this time, multiple wireless routers may be set to implement full coverage of the office area, and if multiple independent wireless routers are used, in order to implement seamless handover, SSIDs, encryption modes, and passwords of the multiple wireless routers need to be set to be the same, so as to implement seamless roaming. Seamless roaming ensures that the currently processed service is not interrupted when a user switches from a wireless network provided by one wireless router to a wireless network provided by another wireless router, which is important when office personnel are active in the office area. Of course, to achieve seamless roaming also needs to satisfy:
1) the names (SSID) of the wireless access points are the same;
2) the addresses allocated by the wireless access points must belong to the same network segment and the same virtual local area network;
3) the wireless access point must adopt the same internet access template;
4) the wireless access points, whose signals cover each other, must use different channels.
Signals among the wireless access points must cover each other, otherwise, a blind area which can not be accessed to the internet occurs. The distance between the wireless access points should therefore be lower than the coverage area of the wireless access points. Thus, when the signal of the currently connected wireless access point is degraded, the wireless access point can roam to a wireless access point with better signal.
Through the above description of seamless roaming, it can be known that the using the scanned second wireless network associated with the currently connected first wireless network as a candidate wireless network includes:
and taking the scanned second wireless network with the same name and password as the first wireless network as a candidate wireless network.
Step S204, determining whether a wireless network exists in the candidate wireless networks, wherein the signal intensity value is greater than a first preset value, and the historical connection record of the wireless network and the mobile terminal meets preset conditions.
Step S205, if there is a wireless network in the candidate wireless networks, where the signal strength value is greater than a first preset value, and the historical connection record of the wireless network with the mobile terminal meets a preset condition, taking the wireless network as a target wireless network, and controlling the mobile terminal to switch from the first wireless network to the target wireless network.
In the embodiment of the present application, the first preset value and the second preset value may be equal or unequal. The number of the target wireless networks may be 1, if the number of the target wireless networks is 1, the mobile terminal may be controlled to be switched from the currently connected first wireless network to the target wireless network, and if the number of the target wireless networks is at least two, one of the target wireless networks needs to be selected, and the mobile terminal is controlled to be switched from the currently connected first wireless network to the selected target wireless network.
As another embodiment of the present application, the controlling the mobile terminal to switch from the first wireless network to the target wireless network includes:
determining the priority of the target wireless network according to the signal strength value of the target wireless network and whether the target wireless network is a wireless network which is historically connected with the mobile terminal;
and controlling the mobile terminal to be switched to a target wireless network with the highest priority from the first wireless network.
In this embodiment of the present application, weight values may be set for two conditions, namely, a signal strength value of a target wireless network and whether the mobile terminal has historically connected to the wireless network, respectively, then a priority of the target wireless network is determined according to the two conditions and the weight values corresponding to the two conditions, and then the mobile terminal is controlled to be switched from a first wireless network currently connected to the target wireless network with the highest priority.
By way of example, the signal strength value is divided into several ranges, where a corresponds to a value in range 1, b corresponds to a value in range 2, c corresponds to a value in range 3, and the weight of the signal strength value is k 1; the value corresponding to the wireless network which is historically connected to the mobile terminal is 1, the value corresponding to the wireless network which is not historically connected to the mobile terminal is 0.5, and the weight corresponding to whether the wireless network which is historically connected to the mobile terminal is k 2. Assuming that the range corresponding to the signal strength value of a target wireless network is range 2, the corresponding value is b, the target wireless network is a wireless network which is historically connected to the mobile terminal, the priority score corresponding to the target wireless network can be obtained as b k1+1 k2, and after the priority scores of all the target wireless networks are calculated, the mobile terminal is controlled to be switched from the first wireless network which is currently connected to the target wireless network with the highest priority score.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
