Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
First embodiment
Fig. 3 is a basic flowchart of a specific absorption rate control method provided in this embodiment, where the specific absorption rate control method includes:
s301, acquiring the frequency band, channel number and transmitting power of the terminal transmitting work.
In the related art, a frequency band is usually used as a reference value to determine whether the specific absorption rate of a terminal in the corresponding frequency band exceeds a standard. In fact, the specific absorption rates of different channels of the unified frequency band are different. Especially, the frequency of 5G is higher and the bandwidth is wider at present, so the specific absorption rate difference between different channels is larger. Therefore, in the embodiment of the present invention, on the basis of obtaining the frequency band and the transmission power of the transmission operation of the terminal, the channel number is also obtained as a reference, so as to determine whether the corresponding specific absorption rate exceeds the standard.
In the embodiment of the invention, the frequency band, the channel number and the transmitting power of the transmitting work of the terminal can be obtained in real time, and meanwhile, the frequency band, the channel number and the transmitting power of the transmitting work of the terminal can be obtained at preset time intervals in order to save the power consumption of the terminal. Specifically, the selection can be performed according to the actual requirements of the user.
It should be understood that there may be a case where the user does not use the terminal, and therefore the user may choose to start using the specific absorption rate control method of the present invention only if necessary, that is, by setting a preset time period, the frequency band, channel number and transmission power of the terminal transmission operation are obtained only within the preset time period. For example, the user usually does not use the terminal at night, so the preset time may be set to 8:00-23:00, which is not limited herein.
And S302, determining the specific absorption rate corresponding to the terminal according to the transmitting power.
It should be understood that a terminal is usually provided with a plurality of antennas, wherein each antenna can be switched as a transmitting antenna of the terminal, and the magnitude of the transmitting power affects the corresponding specific absorption rate, and generally, the larger the transmitting power of the antenna, the larger the specific absorption rate is. Therefore, in the embodiment of the present invention, the transmission power of the current antenna is detected.
It will be appreciated that the mode of operation of the terminal will also result in a difference in specific absorption rate. The working modes of the terminal comprise an earphone mode and a non-earphone mode. Specifically, by monitoring a distance sensor of the terminal, when the distance sensor senses an obstacle within a preset distance, the current working mode of the terminal is a receiver mode; otherwise, the current working mode of the terminal is a non-earphone mode. In the embodiment of the invention, the position of the terminal relative to the human body can be detected through the distance sensor, so that the current working mode of the terminal is determined.
Specifically, when detecting that the receiver is currently in a working state, a system management module in the terminal generates a receiver broadcast, and sends the receiver broadcast to other modules in the mobile terminal to notify the other modules that the terminal is currently in a receiver working mode.
In the embodiment of the present application, how the terminal determines the specific absorption rate corresponding to the transmission power according to the transmission power is not limited. In a possible implementation manner, the terminal may obtain a corresponding relationship between a preset transmission power and a preset specific absorption rate in advance, and determine the specific absorption rate corresponding to the transmission power according to the corresponding relationship. In this implementation manner, the terminal may obtain the corresponding relationship between the preset transmission power and the preset specific absorption rate in the following two manners. In one mode, the terminal obtains a corresponding relationship between a preset transmitting power and a preset specific absorption rate, which are stored locally in advance. For example, the terminal may store a correspondence between a preset transmission power and a preset specific absorption rate, which are obtained through experimental measurement, in the local memory in advance, and when the terminal is used, the correspondence is obtained from the local memory. Therefore, the terminal can rapidly determine the specific absorption rate corresponding to the transmitting power according to the acquired corresponding relation. In another mode, the terminal receives a corresponding relationship between a preset transmission power and a preset specific absorption rate, which are sent by a network device (e.g., RAN). That is, the terminal can obtain not only the correspondence stored locally but also the correspondence existing in other network devices, and in practical application, a suitable implementation manner can be selected according to specific situations. For example, if the local storage space of the terminal is short, the corresponding relationship may be stored in other network devices, and when the terminal needs to use the corresponding relationship, the corresponding relationship may be acquired from other network devices, where the corresponding relationship stored in the network devices may also be obtained through experimental measurement.
And S303, if the specific absorption rate of the terminal is greater than a specific absorption rate threshold value, reducing the specific absorption rate of the terminal according to the frequency band and the channel number.
In the embodiment of the invention, the specific absorption rate of the terminal is reduced according to the frequency band and the channel number. Searching a target specific absorption rate parameter corresponding to a frequency band and a channel number according to the corresponding relation of the preset frequency band, the preset channel number and the specific absorption rate parameter; setting a specific absorption rate parameter of the terminal according to the target specific absorption rate parameter.
It should be understood that the number of channel numbers of each frequency band is relatively large, and if the specific absorption rate parameters of the test terminal under different channels are preset corresponding target specific absorption rate parameters, the workload of actual operation is relatively large. Therefore, it is preferable that the channels of each frequency band are divided into several types of channels, for example, the channels can be divided into typical channels of high, medium, low, and so on, and other channel numbers can be self-defined according to the range of the channels of high, medium, and low. For example, thirteen legal channels of the wifi signal in the 2.4GHz band may define channels 1-4 as low channels; defining channels 5-8 as medium channels; channels 9-13 are defined as low channels. Wherein if the channel number belongs to a low channel, then corresponding to a first target specific absorption rate parameter; if the channel number belongs to the middle channel, the channel number corresponds to a second target specific absorption rate parameter; if the channel number belongs to a high channel, the channel number corresponds to a third target specific absorption rate parameter, which is not limited herein.
In one mode of the embodiment of the application, the terminal obtains a corresponding relationship between a preset frequency band, a preset channel number and a specific absorption rate parameter, which are locally pre-stored. For example, the terminal may store, in the local memory, a correspondence between a preset frequency band, a preset channel number, and a specific absorption rate parameter, which are obtained through experimental measurement, in advance, and when the terminal is used, the correspondence may be obtained locally. Therefore, the terminal can quickly determine the target specific absorption rate parameter corresponding to the channel number according to the acquired corresponding relation. In another mode, the terminal receives a correspondence between a preset frequency band, a preset channel number, and a specific absorption rate parameter sent by a network device (e.g., RAN). That is, the terminal can obtain not only the correspondence stored locally but also the correspondence existing in other network devices, and in practical application, a suitable implementation manner can be selected according to specific situations. For example, if the local storage space of the terminal is short, the corresponding relationship may be stored in other network devices, and when the terminal needs to use the corresponding relationship, the corresponding relationship may be acquired from other network devices, where the corresponding relationship stored in the network devices may also be obtained through experimental measurement.
The corresponding specific absorption rate is also affected due to the different operation modes of the terminal. The working modes of the terminal comprise an earphone mode and a non-earphone mode, and the specific absorption rate of the earphone mode is the specific absorption rate of the head; the specific absorption rate of the non-earpiece mode is the body specific absorption rate. Therefore, the specific absorption rate is judged whether to exceed the standard, and a corresponding specific absorption rate threshold is also set.
