The present invention is by before sending cell handover command to communication terminal, the current down channel quality parameter reported of received communication terminal, and the transmitted power of described cell handover command is sent according to the determination of this down channel quality dynamic state of parameters, then described cell handover command is sent to described communication terminal based on the transmitted power after determining, specifically described down channel quality parameter and predetermined threshold value can be compared, judge whether to need to increase transmitted power according to comparative result; Compared with correlation technique, the application, according to the current down channel quality parameter reported of communication terminal, can determine the transmitted power of current needs dynamically.To avoid in prior art because transmitted power is fixed, and the money waste caused and in order to reduce the high problem of handover failure rate that the wasting of resources causes then.By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment one:
A kind of flow chart that Fig. 1 provides for the present embodiment, comprising:
Step 101: the current down channel quality parameter reported of received communication terminal;
Step 102: according to the transmitted power of the down channel quality parameter information determination switching command got;
This cell handover command is sent to above-mentioned communication terminal based on the transmitted power determined.
In a step 101, the current down channel quality parameter reported of received communication terminal performs before sending cell handover command to communication terminal.The current down channel quality parameter reported of communication terminal is the down channel quality parameter reported communication terminal the last time.The down channel quality parameter that communication terminal the last time reports specifically can send to the ChannelMeasurementReport DETAILED of base station from communication terminal the last time and obtain, and is certainly also not limited to the ChannelMeasurementReport DETAILED described in the present embodiment.In the present embodiment, down channel quality parameter can comprise at least one in following parameter: downlink reception level, downlink reception Signal to Interference plus Noise Ratio, down channel quality indication parameter, the error rate.Certainly, the down channel quality parameter in the application is not limited to the above-mentioned parameter described in the present embodiment, and the parameter obtaining realizing the application's scheme under the enlightenment of the application also belongs to the scope of the present embodiment request protection.
In the present embodiment, send cell handover command by base station to communication terminal, communication terminal carries out cell merge according to the cell handover command received.In the present embodiment, base station sends cell handover command to communication terminal based on the transmitted power after dynamic conditioning.
Further, comprise according to the current down channel quality parameter determination transmitted power reported of communication terminal in the present embodiment: down channel quality parameter and predetermined threshold value are compared, judge whether to need to increase transmitted power according to comparative result; In this way, transmitted power is increased.In the present embodiment, predetermined threshold value can according to concrete application scenarios by obtaining from equipment such as the operation maintenance center OMC of network side or directly arranging in base station.
In the present embodiment, when determining to need to increase transmitted power, can in the following ways in any one:
The first, will send out and establish power to be directly increased to maximum transmit power level;
The second, according to the difference determination transmission power level of down channel quality parameter with corresponding predetermined threshold value.
It is according to the difference between down channel quality parameter and corresponding predetermined threshold value that the second increases transmitted power mode, determine the grade power needing to select, and the transmitted power that grade power is corresponding, be with the difference of first kind of way, selectively can choose the transmitted power of needs, the problem of the wasting of resources can not be caused because of the maximum transmit power choosing greatest level power and correspondence thereof like this; Control more flexible, effective.
When base station increases transmitted power by first kind of way, it specifically can send to the operation maintenance center OMC of the network side of correspondence the request (shown in Figure 7) obtaining corresponding power setting parameter, and obtain corresponding power setting parameter from this operation maintenance center OMC, current transmitted power is set to maximum transmit power level; Base station also directly invoke user can be set in advance in local power setting parameter, directly current transmitted power is set to maximum transmit power level.
When base station increases transmitted power by the second way, it specifically first can obtain the difference of down channel quality parameter and corresponding predetermined threshold value, then corresponding power grade is found from the threshold difference preset with power grade corresponding lists based on this difference obtained, and from this list, obtain corresponding power setting parameter, based on the transmitted power that the power setting optimum configurations obtained is current.Should be understood that, the threshold difference in the present embodiment and power grade corresponding lists can be base station from operation maintenance center OMC Dynamic Acquisition (shown in Figure 7), also can be that user is preset in base station in advance.
