Abstract

The invention relates to a method for reducing the radiation of a mobile phone to a user; when the mobile phone is used to make a call once the mobile phone detects that a special channel is distributed, a signal is sent to remind the user to monitor. The best method is as follows: after the mobile phone detects the ringing of the other part, the signal is sent to remind the user to monitor. The method for reducing the radiation of the mobile phone to the user is applied to a digital mobile telephone system of the mobile phone in a network, can enable the user to effectively avoid the high-radiation time when the mobile is being connected randomly, reduce the radiation of the mobile phone, and reduce the harm of the mobile phone radiation to the human body.

Description

Be used to reduce the method for mobile phone to user's radiation

Technical field

The present invention relates in digital mobile telephone system, utilize signal prompt, reduce the technology of mobile phone radiation human body harm.

Background technology

GSM is a kind of Europe that is widely used in, and a radius of society of other local digital mobile telephone system .GSM networks of the China and the world can reach 35 kilometers, and therefore the mobile phone transmitting power that requires is bigger.The GSM mobile handset 900MHz frequency range maximum transmission power that generally uses at present is 2W (33dBm), and 1800MHz frequency range maximum transmission power is 1W (30dBm) [1].

Mobile phone radiation to the influence of human body still constantly observe with research among, general in the world at present accepted standard is SAR value (SPECIFIC ABSORPTION RATE), it refers to the radio-frequency power of human body unit mass absorption.Because near people's brain (not being with earphone), the distance of mobile phone radiation antenna and human brain is usually less than 15cm when conversation for mobile phone.According to Theory of Electromagnetic Field, under the certain situation of antenna structure and mobile phone and human body relative position, the antenna power output is big more, and the electric field strength that forms in human body is high more, and the RF radiation power of absorption of human body is big more.

GSM mobile handset mainly can be divided into two stages, the one, accidental access stage, the 2nd, traffic communication stage with communicating by letter of gsm system.Mobile phone does not have power control at accidental access stage, for guaranteeing to insert successfully the maximum power that mobile phone can allow with system (the normally maximum transmission power of mobile phone) channel request message [2].If access failure first, mobile phone can be retransmitted nearly 7 times channel request message with the maximum power that system can allow.This accidental access stage is sustainable several seconds under egregious cases.After accidental access stage was finished, mobile phone had been assigned with dedicated channel SDCCH or TCH[3], mobile phone just can be adjusted the transmitting power of mobile phone then according to the instruction of base station, but Initial Trans is still the maximum power that system can allow.The step-length of power adjustment is generally 2dB, the frequency of adjustment be 60ms once.That is to say, reduce the transmitting power of 30dB, need nearly 1 second time.Therefore mobile phone in the caused radio-frequency radiation of accidental access stage much larger than the traffic communication stage.

Therefore how reducing or avoid the radiation of mobile phone radiation, especially accidental access stage, is the problem that GSM mobile handset faces, and supposes that especially a part of user of GSM mobile handset is children.

Summary of the invention

The purpose of this invention is to provide a kind of method of mobile phone that be used to reduce, to reduce the injury of mobile phone radiation to human body to user's radiation.

For achieving the above object, the present invention adopts following technical scheme: a kind ofly be used to reduce the method for mobile phone to user's radiation, mobile phone when Outgoing Call, early than mobile phone detect be assigned with dedicated channel after, send signal, the prompting user can monitor.

Mobile phone detects after the other side's ring, sends signal, and the prompting user can monitor.

Mobile phone from after dialling to having distributed this section period after the dedicated channel, send high radiation alarm signal.

Mobile phone from after dialling to detecting this section period after the other side's ring, send high radiation alarm signal.

Mobile phone detects the other side when connecting phone, sends signal, and the prompting user begins conversation.

Described signal be luminous, one of them or its combination take place, shake.

The present invention is applied to mobile phone in the digital mobile telephone system of network, can allow the user effectively avoid the high radiated time of mobile phone at accidental access stage, reduces the radiation phenomenon of mobile phone, reduces the technology of the present invention beneficial effect of mobile phone radiation to human body harm.

Embodiment

Of the present inventionly be used to reduce the method for mobile phone to user's radiation, mobile phone when Outgoing Call, early than mobile phone detect be assigned with dedicated channel after, send signal, the prompting user can monitor.Reasonable mode is that mobile phone detects after the other side's ring, sends signal, and the prompting user can monitor.Corresponding mobile phone from the dialing after to distributed after the dedicated channel this section period or mobile phone from after dialling to detecting later this section period of the other side's ring, send high radiation alarm signal, to avoid the answering injury that causes in advance.Mobile phone detects the other side when connecting phone, sends signal, and the prompting user begins conversation.Described signal be luminous, one of them or its combination take place, shake.

Embodiment 1:

Utilization is provided with corresponding drives LED light prompt and reduces the application of radiation at mobile phone on mobile phone, LED light is connected prompting and come into plain view, and is easy to use, be applicable to indoor, the open air, use evening on daytime.

Fig. 1 is calling procedure figure of the present invention, comprises mobile phone, CSM network.Mobile phone is before dialing, and red and green LED does not work, at the later accidental access stage of dialing, the red LED warning lamp is earlier bright, has distributed after the dedicated channel deepening of red LED warning lamp, after the other side's ring, the red LED warning lamp is darker, and the green LED warning light brightens.At this moment can paste ear monitors.When answering the call Deng the other side, the red LED warning lamp extinguishes, and has only the green LED warning light at light yellow.At this moment the user can converse.Behind the end of conversation, the green LED warning light extinguishes.

Fig. 2 is led state figure of the present invention, and behind the handset dialing, red LED warning lamp bright green LED warning light goes out.Distributed after the dedicated channel, red LED warning lamp deepening green LED warning light goes out, the caller abnormal conditions, and red LED warning lamp bright green LED warning light is bright.After the other side's ring, the red LED warning lamp is darker, and the green LED warning light brightens.After the other side connected phone, the red LED warning lamp extinguished, and the green LED warning light is bright.Behind the end of conversation, red LED warning lamp green LED warning light extinguishes.

Fig. 3 is a LED sequential chart of the present invention, and the red LED warning lamp is used is LED705/715 in the FN709 circuit diagram, and the green LED warning light is used is LED702/712 in the FN709 circuit diagram.1., 2., 3., 4. the control point can obtain by MTK baseband processor MT6225, can compile out program in conjunction with Fig. 2 and Fig. 3 among Fig. 1, realizes the control to led driver SN3726.
