Embodiment
Core of the present invention is to realize fictitious load in base station (NodeB), needn't be sent to radio network controller owing to realize the data of fictitious load, therefore data do not need to transmit by the interface IUB between base station and the radio network controller, so the realization of fictitious load does not need to take the bandwidth of IUB, only need to keep required ovsf code in the radio network controller (RNC) and get final product.
More specifically say, the present invention transfers to the fictitious load of realizing originally in the base station (NodeB) to realize in radio network controller (RNC), because radio network controller does not relate to the realization of fictitious load, so data do not need to transmit by the interface IUB between base station and the radio network controller.Transmit by IUB owing to be not used in the data that realize fictitious load, therefore fictitious load implementation method of the present invention does not need to take the bandwidth of IUB.
Owing to have a plurality of channels in the communication system, when the test macro performance, need on different channels, fictitious load be set, therefore the random data of realizing downlink artificial load need be sent in the different channels.For fear of produce conflict when a plurality of channels are sent data, then the channel allocation information of putting down in writing in the Orthogonal Variable Spreading Factor OVSF ovsf code need be used in the base station, carries out the distribution of channel according to this channel allocation information.Radio network controller is by obtaining the details that the base station is specifically distributed analog channel with the information interaction of base station.
Be used to realize that the data of fictitious load can adopt following two kinds of methods when eating dishes without rice or wine to transmit:
Un-encoded is directly in the transmission of eating dishes without rice or wine: the transfer of data of using this method to carry out is the random data that directly sends on the analog channel of setting up not through coding, and the random data of un-encoded maps directly in 3GPP TS 25.101 agreements on defined each physical channel;
Encoded back is in the transmission of eating dishes without rice or wine: the transfer of data of using this method to carry out is to being used to realize that the data of fictitious load encode, on the analog channel of setting up, send random data, described encoded random data is mapped in 3GPP TS 25.101 agreements on defined each physical channel through coding.
When the data that are used to realize fictitious load are encoded, can adopt transformat in the following table to produce data and encode.The rate matching attribute of each transmission channel TrCH can all be set to 1, adopt maximum transformat, " NTrCHa=1*81; NTrCHb=1*103; NTrCHc=1*60bits " corresponding as " #1 " in the following table, each TTI produces and encodes corresponding to the data of each transmission channel TF.
| The number of TrChs | 3 | |
| Transport block size | TrCH#a | 39 or 81bits |
| TrCH#b | 103bits | |
| TrCH#c | 60bits | |
| Transport block set size | #1 | N TrCHa＝1*81，N TrCHb＝1*103，N TrCHc＝1*60bits |
| CRC | 12bits(attached only to TrCh#a) | |
| Coding TTI | CC， coding rate＝1/3 for TrCh#a，b coding rate＝1/2 for TrCh#c | |
| 20ms | ||
The specific implementation step of relevant fictitious load is as follows:
Determine the total carrier power value of current area in the communication network to be measured;
Calculate the total power value that this cell downlink fictitious load takies according to the total carrier power value of current area;
According to the actual performance number that takies of each channel in the downlink artificial load performance number calculation plot in communication protocol 3GPP TS 25.101 and the sub-district;
According to the actual down load performance number that takies of each channel that draws through above-mentioned steps, send the random code data to each analog channel, at the downlink artificial load of eating dishes without rice or wine to form power demand.
This implementation method, RNC does not also know the ovsf code word that NodeB uses, but can allow RNC keep required ovsf code.
Below in conjunction with the specific embodiment of the invention accompanying drawing method of downlink artificial load that realizes in the base station of the present invention is elaborated.
Figure 1 shows that the workflow of the present invention's one specific embodiment, the concrete workflow of present embodiment as shown in the figure is as follows:
Step 1, determine the total carrier power value of current area in the communication network to be measured.
The total carrier power value of current area is to weigh the important indicator of communication network capacity and communication capacity, the performance number of the downlink artificial load in the current area is as the part of the total carrier power value of current area, and its numerical value must be less than the total carrier power value in sub-district.
The total carrier power value of current area is to determine by the communication capacity designing requirement of the type of communication network and current area is common.
Step 2, according to current area transmitting power maximum, all the ratio that takies in maximum transmission power of fictitious load channel power value is calculated the total power value that this cell downlink fictitious load takies.For example, when the sub-district maximum transmission power is 800W, all the fictitious load channels account for 40% in maximum transmission power, and the total power value that takies of cell downlink fictitious load is 320W so.
When simulation practical communication process is tested communication system, to take situation be that power according to the actual downstream load that may occur takies situation and simulates to the power of down load in the test model, in the hope of reaching best real simulate effect, measure the actual performance of communication system to be measured.
Since downlink artificial load for the simulating reality loading condition through design in advance, so the ratio that the downlink artificial load performance number takies in the total carrier power value in sub-district is can be predetermined.
After determining the total carrier power value of current area, the ratio that takies in the total carrier power value in sub-district according to the downlink artificial load performance number just can be determined the concrete numerical value of downlink artificial load performance number.
Step 3, according to the actual performance number that takies of each channel in the downlink artificial load performance number calculation plot in communication protocol 3GPP TS 25.101 and the sub-district.
In communication protocol 3GPP TS 25.101, defined the relative power relation of base station according to 16 analog channels of SF=128 foundation.
Relative power relation according to each analog channel under the situation that obtains cell downlink fictitious load gross power, just can calculate the actual down load performance number that takies of each channel according to the power bias of each channel.
The actual down load performance number that takies of each channel that step 4, basis draw sends through encoding or not passing through coded data to each analog channel, is eating dishes without rice or wine to form downlink artificial load.
The random code data that send to each analog channel in the present embodiment can be not through the random code of coding, also can be the random codes through coding.
The described random code of present embodiment includes but not limited to the PN9 sign indicating number.
Since the fictitious load of present embodiment be positioned at the base station eat dishes without rice or wine realize, the random code data that need not to be used to simulate down load send to radio network controller, therefore the random code data that are used to simulate down load are not passed through IUB, do not take the bandwidth of IUB when realizing the fictitious load function.
Radio network controller is not known the code word type of the ovsf code that use the base station in the present embodiment, but can allow RNC keep required ovsf code word.
Figure 2 shows that the systematic schematic diagram of another embodiment of the present invention, the each several part detailed functions is as follows.
