Embodiment
In order to make those skilled in the art person understand better technical scheme in the embodiment of the present invention, and the above-mentioned purpose of the embodiment of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, technical scheme in the embodiment of the present invention is described in further detail.
, referring to Fig. 1, be total to the flow chart of the transmit power controlling method under residential quarter for a kind of multi-site of the embodiment of the present invention.
The present embodiment is applicable to the altogether scene of mobile terminal to mobile terminal under scene, the especially speech business of the switching of target RRU set of locations to the switching of target RRU set of locations under residential quarter of multi-site.This transmit power controlling method can comprise:
In the embodiment of the present invention, this executive agent can be BSS(Base Station Subsystem, base station sub-system), concrete, can be BTS(Base Transceiver Station, base transceiver station), can be also BSC(Base Station Controller, base station controller).
When BSS detected mobile terminal and switches to target RRU set of locations, BSS obtained the power control parameter.If carry out downlink power control, when mobile terminal is switched to target RRU set of locations by former RRU set of locations, BSS obtains the power control parameter from target RRU set of locations, such as the maximum transmission power of target RRU set of locations, the Upper threshold of downlink signal strength and the power control level factor of Lower Threshold, descending path loss and target RRU set of locations etc.; If carry out uplink power control, when switch residential quarter altogether to RRU by former residential quarter when mobile terminal, BSS, from acquisition for mobile terminal power control parameter, reaches residential quarter power switched biasing altogether etc. such as the maximum transmission power of mobile terminal, up path loss, cell uplink power control level target desired value, positive power control power switched biasing.Specifically see also the description of subsequent embodiment.
After BSS obtains the power control parameter, according to these Parameters Calculation power control step-lengths.Concrete, if carry out downlink power control, the BSS power control parameter required according to downlink power control adopts downlink power control step size computation method to calculate and obtains the downlink power control step-length; If carry out uplink power control, the BSS power control parameter required according to uplink power control adopts uplink power control step size computation method to calculate the uplink power control step-length.Specifically see also the description of subsequent embodiment.
After definite power control step-length, further the power control step-length is converted into the power control grade.This conversion process similarly to the prior art, for example, can be power control grade=power control step-length/2, utilizes this method for transformation, and the downlink power control step-length is converted into the downlink power control grade, and the uplink power control step-length is converted into the uplink power control grade.
After obtaining the power control grade, BSS can send the power control grade, and is concrete, if carry out downlink power control, the BSS downlink power control grade that will obtain is sent to target RRU set of locations, so that target RRU set of locations is carried out down transmitting power according to this downlink power control grade, controls; If carry out uplink power control, the BSS uplink power control grade that will obtain is sent to mobile terminal, so that mobile terminal carries out uplink transmission power according to this uplink power control grade, controls, and this mobile terminal can be mobile phone etc.Wherein, the uplink and downlink power control can be carried out respectively, also can carry out simultaneously.
In the embodiment of the present invention when BSS detects mobile terminal and switches to target RRU set of locations, by obtaining the power control parameter, calculate power control step-length and corresponding power control grade, realized the up and/or downlink power control when mobile terminal switches to the RRU set of locations, compare with the method for closing power control in prior art, reduced base station, the energy consumption of mobile terminal and the up-downgoing of network and disturbed.
, referring to Fig. 2, be total to the flow chart of the transmit power controlling method under residential quarter for the another kind of multi-site of the embodiment of the present invention.
The present embodiment is controlled to be example and describes to carry out down transmitting power, and the method can be applied to mobile terminal switches between the RRU set of locations scene, especially under speech business.The method can comprise:
At first BSS judges whether current mobile terminal is switched to target RRU set of locations by former RRU set of locations, when BSS determines that mobile terminal switches to target RRU set of locations, as shown in Figure 3, also namely when t4 arrives constantly, BSS determines the emission state of target RRU set of locations.
wherein, BSS judges whether mobile terminal determines at the determination methods of switching between the RRU set of locations and BSS that the determination methods of target location group emission state can judge comprehensively according to the down-run survey amount of the out-hole run amount of the mobile terminal signal of each RRU set of locations, mobile terminal that each set of locations is launched in single set of locations, the conversion between the emission of two-position group and multiposition group emission state, concrete, for example, the RRU selection judgement cycle of residential quarter arrives current RRU altogether, determine by at least one RRU emission descending carrier signal in described each RRU according to the current down-run survey amount of user terminal and the out-hole run amount of each RRU, or, current down-run survey amount according to user terminal, the out-hole run amount of each RRU and the power requirements of each RRU are determined by at least one RRU emission descending carrier signal in described each RRU, this down channel comprises: Traffic Channel and Separate Dedicated Control Channel, thereby can choose suitable RRU emission descending carrier signal in good time, realize that the RRU emission mode is at single-shot, two, reasonable conversion between multiple pattern.
