Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
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.
As shown in Figure 2, user can assess horizontal range x and the vertical range h of antenna for base station (shown position A) and user's current location (shown position B), horizontal range x and the vertical range h of the information input interface input assessment then providing to mobile phone, mobile phone can be according to preset formula: r so 2=h 2+ x 2, calculate the air line distance r of antenna for base station and current location, and according to preset formula: θ=tan -1(x/h), calculate the angle θ of antenna for base station.It should be noted that, if the vertical range h in above-mentioned formula refers to the distance between antenna for base station and ground, in so above-mentioned formula, it is also conceivable that mobile phone height h1 overhead, the h being about in above-mentioned formula replaces with (h-h1), now height h1 can be inputted by user, or is predisposed to 1.6m or is predisposed to other value.
Fig. 2 is the situation of user in ground, can be with reference to figure 3 when user is on floor.Under this kind of scene, user can assess the height h of antenna for base station (position A in diagram), the horizontal range x of antenna for base station and user's current location (position B in diagram), and the height h1 of floor, when mobile phone receives user and keys in these assessed values by the inputting interface providing, mobile phone can be according to r 2=(h-h1) 2+ x 2, the angle θ=tan of antenna -1[x/ (h-h1)], calculates in the certain above-mentioned formula of the air line distance r of antenna for base station and current location and the angle θ of antenna for base station and also can consider further that mobile phone is from the height of floor end face.
In some execution modes, can obtain by base station the relative position information of antenna for base station and current location.These execution modes refer to that base station can arrange some location parameter, are used for representing the relative position information of the current location of antenna for base station and mobile phone; So, base station is after the request of obtaining relative position information that receives mobile phone, can be for helping positioning function, GPS (Global Positioning System for example, global positioning system), determine the relative position information of the current location of antenna for base station and mobile phone, and be sent to mobile phone by location parameter.
In some execution modes, can also relative to moving of base station, obtain by user the relative position information of antenna for base station and current location.
As shown in Figure 4, due to user is sayed, the horizontal range between antenna for base station and user's current location is difficult for assessment, and assessment poor accuracy.Therefore user can move relative to antenna for base station (diagram Zhong position A), for example, to moving horizontally towards antenna for base station or away from the direction of antenna for base station, and to the height h of the antenna for base station of mobile phone input prediction and relative to the distance x2 moving of antenna for base station, when mobile phone is received these information, can be according to the radiation power value of mobile front and back 2 points (diagram Zhong position B and position C) of record, calculate x2, and then according to the account form of front two execution modes, calculate relative position information (r1 or r2, θ 1 or θ 2).
