That is, when the mobile terminal is in an idle state in the first network to which the mobile terminal is accessed, the mobile terminal performs a network searching operation in the current background to obtain the network searching state parameter, so as to be used as a basis for a subsequent mobile terminal to perform network searching.
And step S120, searching a second network according to the network searching state parameter, and searching a high-energy frequency point in a frequency band list of the second network, or searching a high-energy frequency point in a frequency point list of the second network.
In this embodiment, the frequency point list includes recorded historical registered frequency points and recorded common frequency points, and the frequency band list includes unregistered frequency points, and a part of the frequency points are not overlapped with the frequency points in the frequency point list. And the recorded frequently-used frequency points reside frequency points when the frequently-used frequency points are registered to the operator through the big data collection mobile terminal, and a frequency point set with a large occupation ratio is intercepted. In addition, the frequency point list records and combines the historical registration frequency points and the frequently-used frequency points, and removes redundant items. In addition, the frequently used frequency points and the frequency band list can be preset or updated by the user. Therefore, the network searching of the mobile terminal is not only dependent on the recorded historical registration frequency points, and the full-frequency-band searching is triggered after the multiple-round network searching fails. And when searching the network in the full frequency band, the frequency band priority is added, and the specific frequency band is preferentially searched, so that the speed of returning to the second network in a special scene is improved, and the frequency band priority can be updated through online upgrading, so that the network can be searched and the frequency band is preferentially searched when the frequency band is newly added by an operator.
Further, in this embodiment, the searching for the high-energy frequency point in the frequency band list of the second network is performed when the network searching state parameter and the preset parameter value satisfy the preset condition. In addition, the searching for the high-energy frequency point in the frequency point list of the second network is performed under the condition that the network searching state parameter and the preset parameter value do not meet the preset condition. Wherein the preset conditions include: and the network searching state parameter is N times of a preset parameter value, and N is an integer greater than 1. Therefore, the mobile terminal can determine to search the high-energy frequency points in the frequency band list or the frequency point list, so as to increase the probability of selecting the high-energy frequency points in the frequency band list or the frequency point list, and further increase the probability of returning the mobile terminal from the first network to the second network.

For example, assuming that the first timer value is 5, the first timer counts 1, 2, 3, 4, 5, for example, in sequence. Therefore, the mobile terminal can search the network under a reasonable condition by starting the first timer for counting, and the electric quantity loss caused by the idle state of the mobile terminal is reduced.
In this embodiment, determining the timing of the first timer includes: the timing of the first timer is determined by equation (1), and equation (1) is as follows:

Therefore, when the mobile terminal carries out operations such as making a call, sending a short message and the like, the mobile terminal interrupts the network searching operation so as to ensure that the operations such as making a call, sending a short message and the like can be normally operated.
