Referring to fig. 2, fig. 2 is a flowchart illustrating a method for accessing a wireless network according to another embodiment of the present invention. The execution main body of the method for accessing the wireless network is a terminal, and the terminal is provided with two wireless control chips. The first wireless control chip is used for communicating with the wireless access point, and the second wireless control chip is used for scanning the signal intensity corresponding to the wireless access point in the current area. The wireless control chip is a wireless network control chip, can be a wifi control chip, or a wifi processor and the like. The terminal may be a mobile terminal such as a mobile phone and a tablet computer, and may also be other terminals that can access a wireless network, which is not limited herein. The method for accessing the wireless network in the embodiment comprises the following steps:
s201: the terminal accesses a first wireless network through a first wireless control chip, performs data interaction through the first wireless network, and acquires a second signal intensity value corresponding to a second wireless network through a second wireless control chip when a first signal intensity value corresponding to the first wireless network is smaller than a preset threshold value.
When the terminal accesses the first wireless network through the first wireless control chip and establishes communication connection with the first wireless network for data interaction, whether a first signal intensity value corresponding to a signal sent by the first wireless network and received by the terminal through the first wireless control chip is smaller than a preset threshold value or not is judged.
And when the terminal confirms that the first signal intensity value corresponding to the first wireless network is greater than or equal to the preset threshold value, the terminal does not perform any processing and keeps the communication connection with the first wireless network.
And when the terminal confirms that the first signal intensity value corresponding to the first wireless network is smaller than the preset threshold value, monitoring a wireless signal sent by a second wireless network through a second wireless control chip.
And the terminal acquires a second signal strength value corresponding to the received wireless signal sent by the second wireless network when the terminal confirms that the wireless signal sent by the second wireless network can be monitored.
The first wireless network is a wireless network which is accessed by the terminal at present, and the second wireless network is other available wireless networks except the first wireless network in the coverage area of the current wireless signal. The number of the second wireless networks may be one, or may be at least two, which is not limited herein.
It can be understood that one wireless Access Point corresponds to one wireless network, and the wireless Access Point may be a WiFi Access Point (AP) or a personal hotspot, which is not limited herein.
The terminal may obtain a second signal strength value corresponding to the second wireless network in real time through the second wireless control chip, or may obtain the second signal strength value corresponding to the second wireless network at preset time intervals. The preset time interval can be set according to practical situations, and is not limited herein.
It can be understood that the first signal strength value and the second signal strength value acquired by the terminal may change with the change of the terminal location.
When acquiring the second signal strength value corresponding to the second wireless network, the terminal executes step S202. When the terminal determines that the first signal strength value corresponding to the first wireless network is greater than or equal to the preset threshold, or when the terminal does not acquire the second signal strength value corresponding to the second wireless network, the terminal executes step S204.
S202: and the terminal confirms whether the second signal intensity value is larger than a first signal intensity value corresponding to the first wireless network.
The terminal judges whether a second signal intensity value corresponding to the second wireless network is larger than a first signal intensity value corresponding to the first wireless network.
When the terminal determines that the second signal strength value corresponding to the second wireless network is greater than the first signal strength value corresponding to the first wireless network, the terminal executes step S203; when the terminal determines that the second signal strength value corresponding to the second wireless network is less than or equal to the first signal strength value corresponding to the first wireless network, the terminal executes step S204.
S203: and when the second signal intensity value is larger than the first signal intensity value, the terminal establishes communication connection with the second wireless network through the second wireless control chip and performs data interaction through the second wireless network.
Further, the step of establishing a communication connection between the terminal and a second wireless network through the second wireless control chip may be: and the terminal establishes communication connection of a second wireless network corresponding to the second signal intensity value through the second wireless control chip, performs data interaction through the second wireless network, and disconnects the communication connection between the first wireless control chip and the first wireless network.
And when the terminal confirms that a second signal intensity value corresponding to the second wireless network is greater than the first signal intensity value, the terminal establishes communication connection with the second wireless network through the second wireless control chip, accesses the second wireless network through the second wireless control chip, performs data interaction through the second wireless network, and disconnects the communication connection between the first wireless control chip and the first wireless network. At this time, the terminal switches the currently connected wireless network from the first wireless network to the second wireless network without interrupting network communication.
The number of the second wireless networks corresponding to the second signal strength value greater than the first signal strength value may be one or at least two, which is not limited herein. And when the terminal confirms that the second signal strength value corresponding to each of the at least two second wireless networks is greater than the first signal strength value corresponding to the first wireless network, the terminal establishes communication connection with the second wireless network with the stronger second signal strength value.
Alternatively, step S203 may be: and when the second signal intensity value is greater than the first signal intensity value and the difference value between the second signal intensity value and the first signal intensity value is greater than a preset signal intensity difference value, the terminal establishes communication connection with the second wireless network corresponding to the second signal intensity value through the second wireless control chip and performs data interaction through the second wireless network.
For example, when the terminal accesses the first wireless network through the first wireless control chip, performs data interaction with the first wireless network through the first wireless control chip, and determines that a second signal strength value of at least one second wireless network is greater than a first signal strength value of the first wireless network, it may further determine whether a difference between the second signal strength value and the first signal strength value is greater than a preset signal strength difference, and when it is determined that the difference is greater than or equal to the preset signal strength difference, the terminal establishes a communication connection with the second wireless network corresponding to the second signal strength value through the second wireless control chip, and performs data interaction through the second wireless network. Therefore, the terminal can be prevented from frequently switching the wireless network when the data transmission rates are close. The preset signal intensity difference value can be set according to actual needs, and is not limited here.
The number of the second wireless networks corresponding to the second signal strength value meeting the requirement may be one, or may be at least two, which is not limited herein. The second satisfactory signal strength value is: the second signal strength value is greater than the first signal strength value, and the difference between the second signal strength value and the first signal strength value is greater than or equal to a preset signal strength difference value.
When the terminal confirms that at least two second wireless networks corresponding to the second signal strength values meeting the requirements in the current wireless signal coverage range exist, the terminal can establish communication connection with any second wireless network meeting the requirements through the second wireless control chip, and can also establish communication connection with the second wireless network with stronger or strongest signal strength through the second wireless control chip.
Alternatively, step S203 may include: and when at least two second signal strength values are greater than the first signal strength value, or when at least two second signal strength values are greater than the first signal strength value and the difference value between the at least two second signal strength values and the first signal strength value is greater than a preset signal strength difference value, the terminal establishes communication connection with a second wireless network with the maximum second signal strength value through a second wireless control chip.
For example, when the terminal determines that the second signal strength value of at least one second wireless network is greater than the first signal strength value of the first wireless network, it may further determine whether a difference between the at least two second signal strength values and the first signal strength value is greater than or equal to a preset signal strength difference. The preset signal intensity difference value can be set according to actual needs, and is not limited here.
When the terminal confirms that the difference is larger than or equal to the preset signal intensity difference, the second wireless control chip establishes communication connection with a second wireless network corresponding to the second signal intensity value, and data interaction is carried out through the second wireless network, so that the terminal can be prevented from frequently switching the wireless networks when the data transmission rates are close.
When the terminal confirms that at least two second wireless networks corresponding to the second signal strength values meeting the requirements in the current wireless signal coverage range exist, the terminal establishes communication connection with the second wireless network with the strongest signal strength through the second wireless control chip.
The second signal strength value meeting the requirement is: the at least two second signal strength values are greater than the first signal strength value; or the at least two second signal strength values are larger than the first signal strength value, and the difference value corresponding to each of the at least two second signal strength values and the first signal strength value is larger than or equal to the preset signal strength difference value.
It can be understood that, in this embodiment, the switching of the terminal from the first wireless network to the second wireless network refers to: after the terminal establishes communication connection with the second wireless network through the second wireless control chip, the communication connection between the first wireless control chip and the first wireless network is disconnected, so that the terminal is switched from the first wireless network to the second wireless network, seamless switching is performed through the virtual wireless network interface in the process of switching the wireless network, network resources are not influenced between the terminal and the wireless network, and only one physical wireless network interface is arranged in the terminal. That is, the terminal does not have a communication connection with the wireless network during the handover of the wireless network.
It will be appreciated that when the terminal hands over from the first wireless network to the second wireless network, the terminal identifies the second wireless network as a new first wireless network. That is, the terminal recognizes the currently accessed wireless network as the first wireless network, and the terminal may return to step S201.
S204: when a second signal intensity value corresponding to the second wireless network is not obtained, or when the second signal intensity value is smaller than or equal to the first signal intensity value, the terminal keeps the communication connection with the first wireless network, and data interaction is carried out through the first wireless network.
When the terminal confirms that the first signal intensity value corresponding to the first wireless network is larger than or equal to the preset threshold value, or when the second wireless control chip does not acquire the second signal intensity value corresponding to the second wireless network, or when confirms that the second signal intensity value corresponding to the second wireless network is smaller than or equal to the first signal intensity value, the communication connection between the first wireless control chip and the first wireless network is kept, and data interaction is carried out through the first wireless network.
The rate of the terminal acquiring the network resources through the wireless network has a certain relation with the received signal intensity of the wireless network.
According to the scheme, when the terminal accesses the first wireless network through the first wireless control chip and performs data interaction through the first wireless network, the terminal obtains a second signal intensity value corresponding to the second wireless network through the second wireless control chip; and when the second signal intensity value is larger than the first signal intensity value, establishing communication connection with a second wireless network corresponding to the second signal intensity value through the second wireless control chip, and performing data interaction through the second wireless network. When the terminal confirms that the signal intensity value of the second wireless network is larger than that of the currently accessed wireless network in the coverage area of the current wireless signal, the terminal can seamlessly switch from the first wireless network to the second wireless network with stronger signal intensity under the condition of not interrupting network communication, so that network resources are fully utilized, and the data acquisition rate is improved.
When the terminal confirms that the signal intensity value corresponding to the first wireless network is smaller than the preset threshold value and the second signal intensity value is larger than the first signal intensity value, the terminal automatically switches from the first network to the second wireless network, network resources are obtained through the second wireless network, and the data obtaining speed can be further improved.
When the terminal determines that the second signal strength value is larger than the first signal strength value and the difference between the second signal strength value and the first signal strength value is larger than or equal to a preset signal strength difference value, the terminal automatically switches from the first network to the second wireless network, and the terminal can avoid frequent switching of the wireless networks when the data transmission rates are close.
