Wherein, in a step 408, preset operating conditions has a variety of, and every kind of preset operating conditions is all associated with the default network that the needs of correspondence switch to.
Such as, when being at mobile phone under 3G network or 4G network, can to be the duty of mobile phone be screen lock state and preset operating conditions that current network connection status is non-working condition association 2G network are as default network, so, 2G network is switched to by current 3G network or 4G network when reaching preset operating conditions, both ensure that minimum network connected power consumption, and also allowed for carrying out simple network data exchange. For another example, when mobile phone is under 4G network, can to be the duty of mobile phone be screen lock state and preset operating conditions that current network connection status is use state association 3G network are as default network, so, owing to the network speed of 3G network is higher than 2G network, 3G network is switched to from current 4G network, it is to ensure that higher network transfer speeds, running background program is made normally to use, meanwhile, also low in energy consumption than what consume under 4G network.
Specifically, the transmitting work of general terminal all operates in specific radio-frequency power levels, and it depends not only on the signal to noise ratio of existing use wireless network environment, is also dependent upon the requirement of place network formats simultaneously. Wherein, signal to noise ratio when 3G terminal search network connects may be up to+24dBm, and signal to noise ratio when 2G starting up of terminal search network connects may be up to+33dBm, when the cellular basestation scope that signal to noise ratio is good, its then signal to noise ratio can be low to moderate-20dBm or following.
3GPP (third generation partner program) does not define the specification of electric current, the power distribution curve that GSM (global system for mobile communications) alliance issues in its DG09 service time of battery process of measurement can as reference, it is also possible in determining that WCDMA (WCDMA) equipment is in the relative time amount of different capacity level in representative network. DG09 curve shows, the 3G terminal such as WCDMA typically operate in wider output level, maximum of probability is middle lower power levels, its maximum transmission power distributed area is-20dBm to 9dBm, the DG09 power distribution proportion of WCDMA is as follows: 21dBm to 24dBm ratio is 3.8%, 12dBm to 18dBm ratio is 10.3%, and-50dBm to 9dBm ratio is 85.9%.
It can thus be appreciated that, the probability of the transmitting power of 4G terminal 70% is at more than 20dBm, the probability of 94% is at more than 10dBm, owing to LTE is OFDM (orthogonal frequency division multiplexi) modulation system, the peak-to-average force ratio of its signal is high relative to 2G and 3G a lot, so the power of the transmitting power linear index of LTE is just very big, the power consumption that radio frequency part expends is just very big. and the WCDMA of 3G 90% power probability to be distributed be to 10dBm at-30dBm. therefore, can according to the state of the custom of user and mobile phone, the selection adjusting network of real-time automatic dynamic, such as, if mobile phone is in screen locking or does not use the state of network data, operating handset can be allowed in the 3G network state of low data low-power consumption or 2G network state, if the screen of mobile phone is lighted and/or network data service opens, scan channel one by one can not be carried out, directly it is rapidly switched to advance for the channel frequency of the 4G network of storage, so, under needing the scene carrying out mass data business, can so that the transmitting power of mobile phone be more operated in the 3G network state that transmission power distribution is relatively low by handover network, significantly reduce transmitting power and the power consumption of mobile phone.
Such as, when duty mobile phone being detected is screen lock state, illustrate that user is not just at operating handset, in order to reduce the tranmitting frequency of mobile phone, reduce power consumption, 2G network can be switched to by current 4G network, for another example, can arrange only when the duty of mobile phone is screen lock state and current network connection status is use state, 4G network is switched to 3G network, so, can either there is no just to reduce the tranmitting frequency of mobile phone when operating handset when user, reduce power consumption, also ensure that being smoothed out of ongoing network data exchange behavior, namely ensure that the normal use of running background program. additionally, after entering the 3G network that signal to noise ratio is high, it is still necessary to whether the preset operating conditions continuing monitoring 3G network corresponding is met, if be met, illustrate that user remains without just at operating handset, 3G network can be maintained, and if be unsatisfactory for, illustrate user mobile phone has been carried out unlock or other open operation, now, 4G network should be returned, to promote the transmitting power of mobile phone, meet the operational requirements of user.
Technical scheme is described in detail above in association with accompanying drawing, pass through technical scheme, can be that terminal rationally selects applicable network for different application scenarios, the actual custom of user can either be adapted to, can also effectively reduce the tranmitting frequency of terminal, reduce power consumption, add the stand-by time of terminal, improve Consumer's Experience.
