Email is received with from another terminal.Wherein, content-data may include the music datas such as music, broadcast, such as motion diagram
Any other data of the vision data and game, software of piece, TV programme, video, photo etc. etc..
The major function of base station is just to provide wireless coverage, that is, realizes wireless between wireline communication network and wireless terminal
Signal is transmitted.So the position of base station in a communication network is as shown in Fig. 2 control signaling, audio call or the number of core-network side
By transmission network being sent to base station according to business information, (in 2G, 3G network, signal is first sent to base station controller, then transmits
To base station), signal passes through base band and radio frequency processing in base station side, is then sent on antenna and is launched by radio frequency feed line, eventually
The radio wave that end is launched by wireless channel reception antenna, then demodulates one's own signal.
When terminal receives the radiofrequency signal transmitted from base station, terminal measures the signal strength values of radiofrequency signal.Wherein,
The mode of the signal strength values of terminal measurement radiofrequency signal can have a variety of, such as inquire about current to moden (modem)

The device of equal energy, a final radiofrequency signal is obtained after distribution.
Step S102, when signal strength values are less than preset signal strength value, is determined in running order among terminal
Target devices.
In embodiments of the present invention, a preset signal strength value can be pre-set, it is to be understood that when radio frequency letter
Number signal strength values be less than the preset signal strength value when, illustrate there is interference signal in terminal, namely exist disturb
Source.The problems such as this can cause that signal difference, dropped calls, speech quality are poor, be not turned on to terminal etc., now needs in the terminal
Find above-mentioned interference source.When the signal strength values of radiofrequency signal are greater than or equal to the preset signal strength value, it is determined that terminal
The current influence for being not affected by interference signal, terminates current process.
Further, determine that the method that the target devices of working condition are currently in terminal can have a variety of.It is such as pre-
First determine the device that can be interfered when being worked among terminal to terminal signaling, such as the device such as camera, display screen, flash lamp
Part, to obtain a set, then judges whether the device in the set is current in running order, if being in, really respectively
The fixed device is target devices.
In other embodiments, the device that working condition is completely in terminal can also be obtained, to obtain a set,
In view of being not that the device of all working in terminal can interfere with the signal intensity of terminal, so needing further at this
Target devices are determined among set, such as, judge whether the device among the set can produce interference signal respectively, if so, then
It is target devices to determine the device.
Step S103, obtains the corresponding interference signal intensity value of target devices, and negative according to the generation of interference signal intensity value
Phase signal.
It is determined that after target devices, corresponding interference signal intensity value is obtained according to target devices, in present invention implementation
Among example, multiple default devices and the corresponding interference signal intensity value of the device can be pre-set, such as, pre-establishes pass
The interference signal database of device is preset in terminal, wherein interference signal database includes multiple default devices and default device
The corresponding interference signal intensity value of part.It is determined that after target devices, judging to whether there is and mesh among above-mentioned multiple default devices
Device identical device is marked, if in the presence of, the corresponding interference signal intensity value of default device is obtained, and according to the interference signal
Intensity level generates negative phase signal.
Step S104, radiofrequency signal and negative phase signal are combined, to eliminate the corresponding interference of target devices.
In embodiments of the present invention, useful signal and interference signal are included among radiofrequency signal, by radiofrequency signal and negative
Position signal is combined, such as, by combiner, can be grouped together the signal of the multiband of input output, to eliminate mesh
The corresponding interference of device is marked, the useful signal in radiofrequency signal is obtained.
It is understood that it can also be multiple that the target devices in the embodiment of the present invention, which can be one, so above-mentioned
Negative phase signal can also be one or more.Such as, when target devices are one, that is, a negative phase signal is generated, on
It can be dual-frequency channel merger to state combiner；When target devices are two, that is, generate two negative phase signals, now above-mentioned combining
Device can be tri-frequency combiner, by that analogy.
