Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtained belongs to the scope of protection of the invention.
Fig. 1 is a kind of HNB Poewr control method flow chart of the embodiment of the invention, may further comprise the steps:
S101 defines user equipment (UE) and enters the Microcell that Home eNodeB HNB signal is covered;
S102 determines that described UE does not have the authority that inserts described HNB;
S103 obtains the measurement report of described UE, in the described measurement report, comprises the macrocell signal quality information of described UE present position;
S104, there is co-channel interference in the signal of determining described Microcell according to described macrocell signal quality information for the signal of described macrocell, reduces the transmitting power of described HNB.
The executive agent of each step of said method can be HNB itself, also can be a functional entity that is independent of HNB.Use such scheme, when having no right after UE enters HNB Microcell overlay area,, adjust the transmitting power of HNB according to the signal quality of the macrocell at the place of this UE, thereby reduce the co-channel interference of HNB, reduce and have no right the call drop phenomenon of UE in HNB Microcell overlay area to macrocell.
To be controlled to be example to carry out power below,, the HNB Poewr control method of the embodiment of the invention be described in conjunction with concrete signaling process by HNB self.
Figure 2 shows that the HNB Poewr control method signaling process figure of the embodiment of the invention, may further comprise the steps:
S201, UE sends LAU/RAU message to HNB.
Suppose that UE initially resides in the macrocell, transmit behind the Microcell that covers when UE moves to HNB, at first can set up RRC (Radio Resource Control, Radio Resource control) and connect with HNB, after the RRC connection is set up and finished, UE will initiate position updating process to HNB.
In the present embodiment, UE sends LAU (Location Area Update, the position is upgraded) and/or RAU (Routing Area Update, Routing Area Update) message to HNB.After HNB receives LAU and/or RAU message, can define UE and enter the signal coverage areas of self.
In the present embodiment, HNB is by monitoring LAU and/or RAU message, thereby determined whether that UE enters self overlay area.Be understandable that HNB also can adopt other mode (for example the RRC of monitoring UE transmission sets up request message) to define UE and enter HNB Microcell overlay area, the embodiment of the invention does not limit this.
S202, HNB judges the access authority of UE.
The embodiment of the invention is to propose in the HNB existing co-channel interference situation of Microcell that covers that transmits at having no right UE, in this step, HNB checks whether the UE that enters the overlay area has the authority that inserts HNB, if authentication is not passed through, then further carry out subsequent step, control by power and reduce the interference of HNB macrocell.
If UE has the authority that inserts HNB, then allow UE normally to reside in the Microcell of UE present position, do not need to continue to carry out subsequent step.
S203, HNB send to UE and measure control messages.
The UE that HNB determines newly to enter the overlay area initiates follow-up power control flow: at first send measurement control (measure and control) message to UE, indicate UE that signal quality information is measured for having no right behind the UE.
S204, UE reports HNB with measurement report message.
UE measures the signal quality of macrocell or HNB, and measurement result is carried in measurement report (measurement report) message sends to HNB.
S205, HNB adjust transmitting power according to the measurement report of UE.
HNB collects the measurement report of UE, and measurement report is analyzed, and according to analysis result the transmitting power of HNB is adjusted, and reduces the interference of HNB to macrocell.
Wherein, in the measurement report that UE sends, can comprise the signal quality information of macrocell, for example the chip energy of the received signal code power RSCP_macro of macrocell, macrocell and interference power density are than Ec/Io_macro etc.HNB can analyze the signal quality information of macrocell, judges whether to exist co-channel interference, and the transmitting power of HNB is adjusted accordingly, and reduces the interference of HNB to macrocell.
In addition, in the measurement report that UE sends, can further include the signal quality information of HNB, for example the received signal code power RSCP_micro of HNB.HNB adjusts transmitting power according to the correlation of the signal quality between macrocell and the Microcell, can transmit in the interference to the macrocell signal reducing HNB, guarantees the coverage effect of HNB.
Figure 3 shows that a kind of that the embodiment of the invention provides carries out the method flow diagram that the HNB transmitting power is adjusted according to measurement report, may further comprise the steps:
S301 judges whether UE is in the macro cell base station coverage hole, if, then carry out S302, adjust flow process otherwise finish power.
When the macrocell received signal code power RSCP_macro of UE is very little, illustrate that UE is positioned at the weak overlay area of macrocell, also can be called coverage hole.When UE is in the macro cell base station coverage hole,, also can't guarantee normal talking even there is not the interference of HNB.In this case, the effect of HNB is to replenish the blind area that macro cell base station covers, and can not need the transmitting power of HNB is adjusted, to guarantee the coverage effect of HNB.
In actual applications, can adjust threshold value RSCP_th and be set to-90dBm, promptly judge:
RSCP_macro＞-90dBm
Whether set up, if, then further carry out subsequent step, adjust flow process otherwise finish power.
S302, whether the Ec/Io that judges macrocell is less than default adjustment threshold value.If, then carry out S303, adjust flow process otherwise finish power.
In the present embodiment, assess disturbed condition than Ec/Io_macro according to the chip energy and the interference power density of macrocell.As Ec/Io_macro during less than certain threshold value, think to have stronger co-channel interference, may influence and have no right UE at the normal talking of macrocell, therefore need further to carry out subsequent step the transmitting power of HNB is adjusted.
In actual applications, can adjust threshold value Ec/Io_th and be set to-18dB, promptly judge:
Ec/Io_macro＜-18dB
Whether set up, if, then further carry out subsequent step, adjust flow process otherwise finish power.
S303, the transmitting power of reduction HNB.
When determining to have no right UE when not being in the macro cell base station coverage hole and having stronger co-channel interference, be the signal quality that guarantees macrocell, can suitably reduce the transmitting power of HNB, with the interference of the signal that reduces the HNB emission to the macrocell signal.Be understandable that, for the preferential signal quality that guarantees macrocell, also can be with the transmitting power Close All of HNB.
In the present embodiment, HNB analyzes by the signal quality information to macrocell, determining that UE is not in the macro cell base station coverage hole and exists under the situation of strong co-channel interference, the transmitting power of HNB is being adjusted accordingly, thereby reduce the interference of HNB macrocell.
Be understandable that in actual applications, above-mentioned determining step S301 and the execution sequence of S302 also can exchange, perhaps carry out side by side.And, also can not carry out S301, not consider that promptly whether UE is in the macro cell base station coverage hole, directly determines whether to exist co-channel interference according to Ec/Io_macro, determine whether then the transmitting power of HNB is adjusted accordingly, these do not influence the realization of technical solution of the present invention.
Figure 4 shows that the another kind that the embodiment of the invention provides carries out the method flow diagram that the HNB transmitting power is adjusted according to measurement report, may further comprise the steps:
S401 judges whether UE is in the macro cell base station coverage hole, if, then carry out S302, adjust flow process otherwise finish power.
Whether S402, the Ec/Io that judges macrocell be less than default adjustment threshold value, if then carry out S403, otherwise finish power adjustment flow process.
Wherein, the specific implementation of S401-S402 can be similar with S301-S302, and present embodiment no longer carries out repeat specification.
S403, judge HNB to the path loss of UE whether less than the border path loss threshold value of HNB.
In order to guarantee the coverage of HNB, stipulated that in related protocol HNB must be less than border path loss threshold value PL_th to the path loss PL (Path Loss) of UE, wherein the representative value of PL_th is 47dB, if PL＜PL_th, the signal that current edge is described is stronger, can suitably reduce transmitting power.
Wherein PL is defined as follows:
PL＝P_pilot-RSCP_micro
Therefore in embodiments of the present invention, measurement report is reported by the UE that just enters HNB Microcell overlay area, can think the covering edge of the current HNB of being in of this UE.HNB is at first according to the RSCP_micro in the UE measurement report, and self current transmitting power P_pilot calculates the PL value of HNB to UE, should value and PL_th compare, if PL＜PL_th, then further carry out subsequent step, adjust flow process otherwise finish power.
S404, the transmitting power of reduction HNB.
In the present embodiment, owing to will when reducing interference, guarantee the coverage effect of HNB, therefore need the reduction amplitude of transmitting power be limited.In actual applications, the value that can be similar to PL-PL_th reduces amplitude as the transmitting power that maximum allows.
In actual applications, guarantee to have no right the UE normal talking in the HNB Microcell overlay area, may not need transmitting power is reduced to amplitude peak, on the other hand, enter the UE in the HNB Microcell overlay area, also not necessarily carry out business immediately.Based on above-mentioned situation, in another embodiment of the present invention, also can adopt the mode that progressively reduces the HNB transmitting power, that is to say, when determining to need to reduce the HNB transmitting power, be not once to adjust to the right place, but, progressively reduce the transmitting power of HNB according to step value less than (PL-PL_th).Wherein, step-length adjustment such as the mode that reduces the HNB transmitting power can be, for example reduce 2dB, the mode that also can adopt increment to adjust for example reduces for the first time 2dB, reduces 3dB for the second time, the 3rd place reduces the 4dB...... present embodiment that concrete adjustment mode is not needed to limit at every turn.After each the adjustment, wait for when having UE to enter HNB Microcell overlay area next time, initiate again again to judge flow process, determine whether and to adjust once more.Use this scheme, can be when reducing the interference of HNB to macrocell, reduce reduction degree as far as possible, and stipulated that according to the border path loss threshold value PL_th of HNB the transmitting power of maximum permission reduces amplitude, guarantees the coverage effect of HNB the transmitting power of HNB.
Compare with last embodiment, present embodiment has been further considered the signal quality information of HNB Microcell when determining whether transmitting power adjusted, and can transmit in the interference to the macrocell signal reducing HNB, guarantees the coverage effect of HNB.Be understandable that, in actual applications, above-mentioned determining step S401, S402, the execution sequence of S403 also can exchange, perhaps carry out side by side, and, can not consider equally whether UE is in the macro cell base station coverage hole, does not promptly carry out S401, and these do not influence the realization of technical solution of the present invention.
Be understandable that the power control scheme that the invention described above embodiment provided can be to automatically perform, that is: whether detection in real time has UE to enter HNB Microcell overlay area and carries out follow-up flow process; Also can be periodically to carry out or the manual activation execution, for the mode of periodically carrying out or manual activation is carried out, can set in advance one and detect duration T0, whether detection has UE to enter HNB Microcell overlay area and carries out follow-up flow process in the duration scope of T0.For carry out the scheme that power is adjusted according to the PL value, no matter adopt above-mentioned which kind of mode, after the transmitting power of HNB has been adjusted to minimum value, can stop adjustment to power.
In addition, if the HNB power down after then starting shooting once more, can revert to initial value with the transmitting power of HNB.
