Embodiment
The invention provides a kind of wireless signal switching method, be applied to a portable electronic communication device, by detecting signal strength signal intensity (the Received Signal StrengthIndicator of the received WiFi signal of portable electronic communication device, RSSI), whether be connected to other WiFi access point (Access Point with decision, AP) or switch to a general packet wireless radio service (General Packet Radio Service, GPRS) base station, and be maintained unbroken on line state of portable electronic communication device and wireless network.
Please refer to Fig. 1, it illustrates the flow chart according to the wireless signal switching method of preferred embodiment of the present invention.This wireless signal switching method is to be applied to a portable electronic communication device, for example is a mobile phone, so is not limited to this.In step S100, link one first wireless network corresponding to one the one WiFi signal.In step S110, detect a WiFi RSSI of signals.In step S120,, detect whether there are a plurality of another WiFi signals if a WiFi RSSI of signals is lower than a default value.In step S130, compare these another WiFi RSSI of signals, and link pairing another wireless network of another WiFi signal with maximum RSSI.
Please refer to Fig. 2, it illustrates the detail flowchart according to the wireless signal switching method of preferred embodiment of the present invention.In second figure, lifting portable electronic communication device now is that mobile phone is done explanation, so is not limited to this.In step S200, mobile phone detects whether receive a WiFi signal.If mobile phone does not receive the WiFi signal, then represent mobile phone not to be in the service range of arbitrary WiFi access point, so in step S220, mobile phone connects a GPRS base station to login a wireless network.If mobile phone detects and receive a WiFi signal, then in step S230, the mobile phone connection is sent a WiFi access point of this WiFi signal to login wireless network.
In step S240, mobile phone detects the WiFi RSSI of signals that is received and whether is lower than a default value when logining wireless network.If the WiFi RSSI of signals that is received is lower than default value, then mobile phone may be in the edge of present WiFi access point service range and make that the WiFi signal receives bad, can cause mobile phone possibly can't connect the WiFi access point and interrupts and being connected of wireless network.So in step S250, mobile phone detects whether receive the WiFi signal that other WiFi access point sends.In step S240, mobile phone comes down to continue to detect the WiFi RSSI of signals that is received, and so is not limited to this, also can detect once every short time interval, as long as keep unbroken on line state of mobile phone and wireless network.
If mobile phone can receive the WiFi signal that other WiFi access point is sent, then in step S260, mobile phone can select to have in these other WiFi signals the WiFi signal of maximum RSSI, and connection is sent the WiFi access point of this WiFi signal with maximum RSSI to login wireless network.Repeating step S240 then.Step S240～S260 can utilize a Thread (thread) to carry out infinite circulation in fact and realize, yet is not limited to this.In fact, mobile phone can continue to detect the WiFi RSSI of signals that the WiFi access point that connected sends, and stops incident up to one and is triggered and stops logining wireless network, and Thread also can be switched off and no longer detects the WiFi RSSI of signals simultaneously.Wherein, this stop incident for example for the user do not want the online etc.
If in step S250, mobile phone can't receive other WiFi signal, then represents the residing position of mobile phone not to be positioned at the service range of other WiFi access point.Though therefore present WiFi signal has low RSSI, mobile phone still must continue to connect current WiFi access point to connect wireless network.Then, in step S270, mobile phone can judge whether current WiFi signal disappears.If current WiFi blackout, then mobile phone is not in the service range of any WiFi access point.So subsequent steps S220, mobile phone connects a GPRS base station to keep the state of logining wireless network.
