Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the method for switching network of mobile terminal of the present invention is proposed.
Please refer to Fig. 3 A, it is the method flow diagram of method for switching network first embodiment of a kind of mobile terminal of the present invention, and as shown in the figure, the method comprises the following steps:
S11: confirm that current network is the first connection mode of preferential attachment, obtain the transmission actual parameter of current network.
Generally speaking, the network connection mode of mobile terminal from transmitting procedure, mainly two kinds.One is self direct access network, such as by SIM card with the mode access network of mobile communication; Another kind accesses other intermediary of network equipment thus access network by various short-distance wireless communication modes, such as, by Wi-Fi network interface card access Wi-Fi or the network share for Bluetooth etc. being accessed other mobile terminal by Bluetooth chip.And except the situation of only a few, the overwhelming majority is all that the network realizing mobile terminal by SIM card and Wi-Fi network interface card is connected.
For the use habit of user, any access network in SIM card or Wi-Fi network interface card selects freely, certainly, the acquiescence of prior art is generally by Wi-Fi network interface card access of radio network, specifically as shown in Figure 3 B, two kinds of network schemers, what priority was higher is Wi-Fi network interface card pattern.User can select preferentially by SIM card access network, and now the first connection mode is SIM card access, and the second connection mode is the access of Wi-Fi network interface card; Also can select preferentially by Wi-Fi network interface card access network, now the first connection mode is the access of Wi-Fi network interface card, and the second connection mode is SIM card access.Wherein a when access, another kind disconnects forbidding, the smooth and power consumption increase of the transfer of data avoiding the network state in use procedure change causing.
For network data transmission, the transmission actual parameter in order to the virtual condition of data of description transmission comprises the intensity instruction of data transmission rate, data reception rate and current network signal.
Message transmission rate when data transmission rate (tx) refers to that mobile terminal outwards sends information, such as, message transmission rate when sending information by Wi-Fi Hotspot to network by Wi-Fi network interface card.
Data reception rate (rx) refers to that mobile terminal receives the message transmission rate of the information of outside input, such as, message transmission rate when receiving by SIM card the information that base station sends.
Intensity instruction (the rssi of current network signal, ReceiveSignalStrengthIndicator) for describing wideband received power, current network signal intensity instruction by carry out at numeric field power integral then anti-antenna opening of shifting onto obtain, this parameter is as the foundation judging system interference.
Described transmission speed and the state stability of current network by above-mentioned parameter, and then connect the criterion whether switched as network.
S12: the transmission lower limit parameter reading the first connection mode preset, compares transmission actual parameter and transmission lower limit parameter.
Transmission lower limit parameter is for describing the lowest tolerated state under a kind of connection mode, also be the comparison standard of follow-up judgement, if the connection status of reality is better than lowest tolerated state, so naturally keep current connection status, proceed network and connect and transfer of data; If the connection status of reality is also poorer than lowest tolerated state, so handover network connects, and enters the second connection mode, to obtain better network connection state.
For different connection modes, transmission lower limit parameter can be identical, also can be different.Generally speaking, the transmission speed of Wi-Fi network is greater than the transmission speed of mobile communication network, if adopt identical transmission lower limit parameter, only have when Wi-Fi Hotspot access great amount of terminals, or certain terminal occupies a large amount of transfer resources and just can produce and be switched to SIM card pattern from Wi-Fi network interface card pattern.Certainly, along with the fast development of mobile communication technology, the transmission speed of SIM card pattern makes great progress, and both possess quite close transmittability, can arrange identical transmission lower limit parameter, also ensures the accurate switching that network connects.For mobile communication network comparatively early, preferably SIM card pattern and Wi-Fi network interface card pattern are set to different transmission lower limit parameter.
S13: all corresponding to when transmitting lower limit parameter when transmitting actual parameter, switches to the second connection mode for subsequent use by current network.
It should be noted that, in this programme, when only having all transmission actual parameters all low than the transmission lower limit parameter of correspondence, just current network can be switched, if one of them or two network parameters are lower slightly, switch without the need to connecting current network, maintaining the statusquo.

S24: the connectivity option obtaining the second connection mode, the connectivity option that access connectivity option medium priority is the highest or signal is the strongest.
For the connectivity option of the second connection mode, the priority of each connectivity option can be preset, certainly, also can judge according to the signal strength signal intensity of connectivity option.
S25: disconnect the first connection mode.
When network connects, only retain a connection mode, to reduce the fluctuation of network connection state, avoid the increase of data transmission fault that in data transmission procedure, the switching of network connection state causes and mobile terminal power consumption.
S26: if the second connection mode connection failure, current network is switched to the first connection mode.
If the second connection mode connection failure, so network to be switched to after the second connection mode mobile terminal cannot access network, now started the normal use having influence on mobile terminal.Current network is switched back the first connection mode, ensure that the network of mobile terminal connects available.
S27: corresponding to when transmitting lower limit parameter when transmitting actual parameter part, output network switching command receive window.
If transmission actual parameter part is corresponding to transmission lower limit parameter, so network connects and can switch, also can not switch, now as shown in Figure 4 D, at the screen output network switching command receive window of mobile terminal, when receiving instruction, network is switched to connectivity option corresponding in the connection mode and this pattern that instruction points to.
