Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 1, be the main flow figure of a kind of resource regulating method that the embodiment of the present invention provides, be described below.
Step 101: Long Term Evolution LTE base station detects the state of the channel in unauthorized frequency range.
First described LTE base station can detect the state of the channel in described unauthorized frequency range.The state of the detection channel described in the embodiment of the present invention, mainly refers to and detects that channel is current is in running orderly still in idle condition.
In the embodiment of the present invention, described LTE base station detects the state of the channel in described unauthorized frequency range, specifically can refer to that the master control baseband processor in described LTE base station detects the state of the channel in described unauthorized frequency range, described master control baseband processor refers to can the baseband processor of control LTE baseband processor and WLAN baseband processor.Wherein, described LTE baseband processor and described WLAN baseband processor can be positioned at described LTE base station side.
Refer to Fig. 2, for the one in the embodiment of the present invention realizes block diagram.Baseband processor in Fig. 2 is described master control baseband processor.In Fig. 21 represents mandate (license) frequency range, the frequency ranges such as such as 1.9Ghz, 2.3Ghz, 2.6Ghz, and 2 represent described unauthorized frequency range, the frequency ranges such as such as 5.8Ghz.As can be seen from Figure 2, the described master control baseband processor in Fig. 2 can control described mandate frequency range and described unauthorized frequency range.
Base station main carrier works in described mandate frequency range, and in described mandate frequency range broadcast system message, comprise the distribution to terminal resource and scheduling in this system message.
In this embodiment, described LTE base station detects the state of the channel in described unauthorized frequency range, can be specifically: described master control baseband processor keeps the monitoring to the channel in described unauthorized frequency range always, obtain channel-monitoring object information, described master control baseband processor can determine the state of the channel in described unauthorized frequency range according to described channel-monitoring object information.
Step 102: if according to testing result, described LTE base station determines that the channel in described unauthorized frequency range is in idle condition, then in described unauthorized frequency range, send public reference signal, described public reference signal is used to indicate wlan system subscriber equipment and prohibits the use the channel described unauthorized frequency range being in idle condition to carry out transfer of data.
In the embodiment of the present invention, described testing result can refer to described channel-monitoring object information.
Described master control baseband processor sends described public reference signal in described unauthorized frequency range, because described wlan system subscriber equipment works in described unauthorized frequency range, therefore described wlan system subscriber equipment can receive described public reference signal, thus can determine to forbid that described wlan system subscriber equipment uses the channel described unauthorized frequency range being in idle condition to carry out transfer of data according to described public reference signal.In the embodiment of the present invention, described wlan system subscriber equipment can only have one, or also can have multiple.
When described channel-monitoring object information represents the channel idle in described unauthorized frequency range, described master control baseband processor sends described public reference signal in described unauthorized frequency range, and described public reference signal can be received and demodulation by wlan system subscriber equipment.
Described public reference signal can be equivalent to an empty WLAN frame.The field of described public reference signal such as can comprise: PLCP(Physical Layer Convergence Procedure, Physical layer convergence protocol) head, frame controls mark, the duration of busy channel, IEEE802(Institute of Electricaland Electronics Engineers, Institute of Electrical and Electric Engineers 802 specification) address range, check field, etc., specifically can reference diagram 3.
Wherein, the lead code of wlan system can be comprised in PLCP head.
Wherein, the duration of busy channel specifies the time span needing the channel taken in described unauthorized frequency range, the duration of this busy channel also can be called time span information, described time span information is what pre-set, can be such as arranged by LTE system, or also directly can be fixed as a value, such as be fixed as N millisecond, N is integer, and described time span information is used to indicate wlan system subscriber equipment and prohibits the use the channel described unauthorized frequency range being in idle condition to carry out the time span of transfer of data.After wlan system subscriber equipment receives this public reference signal, in described time span, forbid being in the channel of idle condition in described unauthorized frequency range transmitting data, ensure that the channel described unauthorized frequency range being in idle condition is available in the time span corresponding to described time span information.
Step 103: the channel dispatch described unauthorized frequency range being in idle condition uses to LTE system subscriber equipment by described LTE base station.
After described master control baseband processor sends described public reference signal in described unauthorized frequency range, the channel dispatch described unauthorized frequency range being in idle condition can be used to described LTE system subscriber equipment, in described time span, described LTE system subscriber equipment can be in the channel of idle condition and transmit data in described unauthorized frequency range, namely strive for that described time span carrys out deal with data for described LTE system subscriber equipment, simultaneously, in described time span, described wlan system subscriber equipment can not carry out transfer of data on the same channel, ensure channel a moment only for the subscriber equipment of a system, avoid the congestion phenomenon that channel may occur, the interference phenomenon that the data that simultaneously it also avoid two systems may produce each other, ensure the reliability that data send, also improve the speed of transfer of data.
Refer to Fig. 4, based on same inventive concept, the embodiment of the present invention provides another kind of resource regulating method, and the main flow of described method is as follows:
Step 401:LTE baseband processor detects the state of the channel in unauthorized frequency range.
