ITU-T (International Telecommunication Union Telecommunication Standardization Sector, international telecommunication union telecommunication's Standardization Sector) at it, K.52 in recommendation, introduced about observing the guide of elect magnetic field person exposure limits, and introduced therein EMF (Electromagnetic Fields, electro magnetic field electromagnetic radiation) the simple appraisal procedure exposing, and the calculating formula of the electromagnetic radiation intensity (also referred to as " power density ") that calculates certain position is provided.The embodiment of the present invention is at ITU-T K.52 on the basis of recommendation, provides a kind of and can facilitate user to assess at any time method and the mobile terminal of fail safe that current location is subject to the electromagnetic radiation of antenna for base station.
Please refer to Fig. 1, is the schematic flow sheet of the first embodiment of a kind of method of assessing electromagnetic radiation fail safe of the present invention.The executive agent of the embodiment of the method for Fig. 1 can be can realize the mobile terminal of functions such as calling, receive and dispatch note, wireless Internet access such as mobile phone etc.The method flow of Fig. 1 comprises:
Step S11, obtains antenna for base station at the relative position information of radiation power value and antenna for base station and the current location of current location.
Wherein, current location refers to the residing position of mobile terminal current time of carrying out the present embodiment.Radiation power value is called again " signal strength signal intensity that mobile phone receives ", this value is one of indispensable parameter of mobile phone normal communication, general regular handset can directly not provide user interface to show this parameter, and smart mobile phone generally can provide user interface to show this parameter, for example, show: " current demand signal intensity is-56dBm "; When therefore the mobile phone of the present embodiment need to be assessed the electromagnetic radiation fail safe of current location, can directly inquire about base station in the radiation power value of current location by polling routine.
The relative position information of antenna for base station and current location comprises: the air line distance of antenna for base station and current location and the angle of base station; This relative position information is by the out of Memory obtaining, to calculate or directly to obtain, for example:
In some execution modes, according to user's input, obtain the relative position information of antenna for base station and current location.
