Step 205, if described initial signal quality parameter thresholding is more than the second predetermined threshold value, presets according to second and adjusts Mode reduces described initial signal quality parameter thresholding;
In a kind of preferred embodiments of the embodiment of the present invention, described preset adjustment mode according to second and reduce described initial letter The step of number mass parameter thresholding, including: according to formula Q=Tq-1 or Q=Q1-[(Q1-Tq)/N], reduce described initial signal Mass parameter thresholding;
Wherein, Q1For initial signal quality parameter thresholding, Q is target signal qualities Parameters threshold, TqIt is second to preset threshold Value, N is the positive integer more than 1.
Specifically, if described initial signal quality parameter thresholding is more than the second predetermined threshold value, i.e. initial signal quality ginseng Thresholding during number thresholding is planned than general empirical value or carrier technologies is high, it is believed that this initial signal quality parameter door Limit is too high, so reducing described initial signal quality parameter thresholding further, reduces the door of too high LTE network community Limit, improves the probability accessing LTE network.
In actual application, when described initial signal quality parameter thresholding is reduced to want little than the first predetermined threshold value, i.e. recognize Thresholding in planning than general empirical value or carrier technologies for it is low, it may be determined that the described initial signal matter after reduction Amount Parameters threshold is Target Signal Strength Parameters threshold.
It should be noted that in the embodiment of the present invention, it should be noted that obtain Target Signal Strength Parameters threshold and institute After stating target signal qualities Parameters threshold, described mobile terminal can send thresholding and change information to base station side, base station side response Described thresholding changes information, determines that described Target Signal Strength Parameters threshold and described target signal qualities Parameters threshold are for mobile The access thresholding of terminal.
Step 206, according to described Target Signal Strength Parameters threshold and described target signal qualities Parameters threshold, accesses institute State LTE network.
In a kind of preferred embodiment of the embodiment of the present invention, described according to described Target Signal Strength Parameters threshold with described Target signal qualities Parameters threshold, accesses the step of described LTE network, including: obtain the signal quality of described LTE network community Parameter and signal strength parameter;By the signal quality parameter of described LTE network community and signal strength parameter respectively with described mesh Mark signal quality parameter thresholding and described Target Signal Strength Parameters threshold compare;If the signal of described LTE network community Mass parameter is more than described more than the signal strength parameter of described target signal qualities Parameters threshold and described LTE network community Target Signal Strength Parameters threshold, then be attached to the community of described LTE network.
In the embodiment of the present invention, it is judged that whether described initial signal intensity Parameters threshold is more than the first predetermined threshold value, if institute When stating initial signal intensity Parameters threshold more than the first predetermined threshold value, reduce described initial signal intensity Parameters threshold, it is judged that institute State whether initial signal quality parameter thresholding is more than the second predetermined threshold value, if described initial signal quality parameter thresholding is more than second During predetermined threshold value, reducing described initial signal intensity Parameters threshold, mobile terminal is according to described Target Signal Strength Parameters threshold With described target signal qualities Parameters threshold, being attached to described LTE network, the embodiment of the present invention arranges two predetermined threshold value, point It is not used for adjusting described initial signal intensity Parameters threshold and initial signal quality parameter thresholding, reduces too high LTE network little The thresholding in district, improves the probability accessing LTE network, and the online improving user is experienced.
It should be noted that for embodiment of the method, in order to be briefly described, therefore it is all expressed as a series of action group Closing, but those skilled in the art should know, the embodiment of the present invention is not limited by described sequence of movement, because depending on According to the embodiment of the present invention, some step can use other orders or carry out simultaneously.Secondly, those skilled in the art also should Knowing, embodiment described in this description belongs to preferred embodiment, and the involved action not necessarily present invention implements Necessary to example.
