The embodiments of the invention provide a kind of switching method of user equipment, this method is applied to the base of GSM Stand, the GSM can be any cell mobile communication systems, such as LTE（Long Term Evolution, for a long time Evolution technology）、GSM（Global System of Mobile communications, global system for mobile communications）、UMTS （Universal Mobile Telecommunications System, UMTS）Deng.As shown in figure 1, should Method includes：
101st, base station know there is a situation where adjacent frequency interference after, by circuit loss value be more than path loss threshold value user equipment be defined as First user equipment.
Frequency spectrum is using being fixed allocation at present, and TV business is using hundreds of million propagation characteristics of below 800MHz are good, covering is excellent The big frequency spectrum of gesture, but have the frequency range being largely underutilized, i.e. white spaces in this section of frequency spectrum.Existing mobile communication system System utilizes cognitive radio technology cognitive radio communication environment, dynamically can detect and efficiently access the blank of television services Frequency range.But provided according to FCC, if the white spaces of GSM access TV business are main subscriber signal, TV signals exist When adjacent frequency occurs, in order to avoid being interfered to the TV signals of adjacent frequency, the maximum hair of all user equipmenies in base station range Power is sent to need to drop to 16dBm from 20dBm.
Wherein, for LTE system, the base station can be specifically eNB.Adjacent frequency interference refers to exist in adjacent cell The channel adjacent with this cell operation channel, the situation of caused adjacent channel interference when there is signal to occur in adjacent channel. Base station is perceived by itself, measurement knows that adjacent frequency is disturbed be present, or reception other equipment is perceived, the adjacent frequency of measurement is done The message or database disturbed notice base station before adjacent frequency disturbed condition occurs.Path loss refers to link load or link is pre- Calculate, be the calculating carried out to gain in whole information transfer process and loss, generally can be from transmitting for estimating signal Hold the maximum distance of receiving terminal.
If the circuit loss value of the user equipment is more than path loss threshold value, base station thinks that user equipment is sent to the signal of base station Path loss is larger, and when adjacent frequency has TV signals to occur, the maximum transmit power of user equipment is required according to FCC regulation Reduce, the possible upward signal of user equipment that such circuit loss value is more than path loss threshold value is limited, can not be with base station proper communication.In order to Avoid user equipment can not proper communication, base station by circuit loss value be more than path loss threshold value user equipment be the first user equipment determine For the user equipment to be switched.
102nd, the base station switches over to first user equipment.
In order to ensure that user equipment communication is unaffected, base station is after the first user equipment is determined, in time by described the One user equipment is switched to can be with other neighbor cells of proper communication or other carrier waves.
The embodiment of the present invention additionally provides a kind of switching method of user equipment, as shown in Fig. 2 this method includes：
201st, the user equipment receives the path loss that base station is sent and reports request message, and measures circuit loss value.
Wherein, base station can be by perceiving, measuring or database notification knows adjacent frequency disturbed condition.Know in base station and deposit After the situation of adjacent frequency interference, the user equipment of base station all RRC connected states into serving cell sends path loss and reports request to disappear Breath.
For example, one can be increased in the UE information request UE Information Request message of LTE protocol Individual path loss reports the information of prompting, such as pathloss Report Request.The user equipment receives the path loss and reported After request message, filtered circuit loss value, such as the UE information responses UE Information in LTE protocol are reported to base station Increase the information for reporting circuit loss value in Response message, such as：pathloss Report.
202nd, the user equipment reports the circuit loss value of its measurement to the base station, to cause the base station by the path loss The user equipment that value is more than path loss threshold value is defined as the first user equipment.
Wherein, the base station presets path loss threshold value or by the way that path loss threshold value is calculated.Path loss threshold value is set by user The sensitivity of standby maximum transmission power and base station receiver obtains.The sensitivity of base station receiver refers to that base station can receive And can normal work lowest signal intensity.The circuit loss value of measurement is carried when the user equipment is sent to the base station After measurement report, the base station will compare according to the circuit loss value received with the path loss threshold value, when user equipment measurement Circuit loss value is more than the path loss threshold value, then it is the first user equipment that can determine the user equipment.
If the 203, the user equipment is defined as first user equipment by the base station, switch over.
Because the circuit loss value of first user equipment is more than path loss threshold value, base station thinks that the first user equipment is sent to base The path loss for the signal stood is larger, so when adjacent frequency has TV signals to occur, according to the maximum of FCC regulation user equipment Transmit power is reduced, and the possible upward signal of the first user equipment that so maximum transmit power reduces is limited, can not be with base station just Normal open is believed.In order to ensure first user equipment can proper communication, base station, can be timely after the first user equipment is determined First user equipment is switched on neighbor cell or other carrier waves, the first user equipment matching somebody with somebody according to the base station Put and switch over.
The embodiment of the present invention additionally provides a kind of switching method of user equipment, as shown in figure 3, this method includes：
301st, the user equipment receives the path loss threshold value that the base station is sent.
Wherein, base station is perceived by itself, measurement knows that adjacent frequency is disturbed be present, or receives other equipment sense The message or database of the adjacent frequency interference know, measured notice base station before adjacent frequency disturbed condition occurs.Adjacent frequency is disturbed Refer in adjacent cell and the channel adjacent with this cell operation channel be present, it is caused adjacent when there is signal to occur in adjacent channel The situation of channel interference.
When adjacent frequency there are TV signals to occur, provided according to FCC, the transmit power of user equipment needs to decline from 20dBm To 16dBm.Base station preset a path loss threshold value or according to the ascending power of one user equipment of power calculation after decline by The path loss threshold value of limit, is then sent to user equipment.Wherein, maximum transmission power and base station of the path loss threshold value by user equipment The sensitivity of receiver obtains.The sensitivity of base station receiver refers to minimum letter that base station can receive and energy normal work Number intensity.
302nd, the user equipment measurement circuit loss value.
303rd, the user equipment judges whether the circuit loss value of its measurement is more than the path loss threshold value.
If the 304, the circuit loss value of user equipment measurement is more than the path loss threshold value, the user equipment is to the base Stand and send the limited configured information of ascending power, to cause the base station to send the use of the limited configured information of the ascending power Family equipment is defined as first user equipment.
Wherein, after the user equipment receives the path loss threshold value of base station transmission, the circuit loss value of itself is measured, and by two Person is compared.When the circuit loss value of user equipment is more than path loss threshold value, the user equipment sends ascending power to base station and is limited Configured information.So after receiving ascending power and being limited configured information, base station thinks that the user equipment is sent to base station for base station Signal path loss it is larger, so when adjacent frequency has TV signals to occur, sent according to FCC the maximum of regulation user equipment Power can be lowered, and the possible upward signal of user equipment that such circuit loss value is more than path loss threshold value is limited, can not be normal with base station Communication.In order to avoid user equipment can not proper communication, base station by circuit loss value be more than path loss threshold value user equipment be defined as will The user equipment switched in time, i.e. the first user equipment.
If the 305, the user equipment is defined as first user equipment by the base station, switch over.
Because the circuit loss value of first user equipment is more than path loss threshold value, in order to ensure that first user equipment is normal Communication, the base station timely can be switched to neighbor cell by first user equipment after the first user equipment is determined Or on other carrier waves.
The embodiment provides a kind of switching method of user equipment, this method is included when base station is known in the presence of adjacent After the situation of frequency interference, the user equipment that circuit loss value is more than path loss threshold value by the base station is defined as the first user equipment, then The base station switches over to first user equipment.So described base station can be by first in the base station range User equipment, i.e., the upward signal meeting limited users equipment after the reduction of maximum transmit power, is switched in time, so as to Ensure the proper communication of user equipment.
