Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of method of testing and device of mobile communication system service.
Background technology
In modern wireless communication systems, particularly in adopting code division multiple access (CDMA) third generation mobile system, adopted the state-of-the-art technology of current electronics, especially adopted technology such as software radio, joint-detection, smart antenna, uplink synchronous in the TD-SCDMA system, these technology can more effectively realize PC (power control), TA (time in advance/synchronously), HO (switching), DCA rudimentary algorithms such as (dynamic channel allocation).Therefore, around the integration testing that these algorithms carried out, in research and development test, important status is arranged, need only the problem that exists in a certain function in certain algorithm in the above-mentioned test of heuristics and in test, fail to be found all and can cause immeasurable baneful influence systematic function to the TD-SCDMA system.
The 3-G (Generation Three mobile communication system) network configuration as shown in Figure 1, for this system, the tester mainly is one or more test datas that obtain of utilizing in the testing tool shown in Figure 2.Wherein, the air-interface information output port is used for display radio mouth message content; The module message output port is used for exporting message content between inner each module in base station (NodeB); Protocol analyzer is used to detect the message of Abis/Iub, A/Iu mouth.Then these test datas are carried out manual analysis and judge the whether complete and correct realization of RRM (RRM) algorithm function.But present this test mode can not make things convenient for, accurately and all sidedly carry out proof of algorithm, mainly contains the reason of following several respects:
1, verification algorithm need manually be consulted and analyze the data file that different output ports obtain, and this needs the tester that the decoding of the clear various message of enough knowledge and experiences and the data that needs are analyzed are arranged, and human factor is very big to the judgement influence of test result.Such as: when verifying uplink external ring power control, BLER/BER (BLER (block error rate)/error rate) thresholding need be set, increase and disturb, can continue the test judgement external circule power control be controlled at BLER in the scope of OM (operational administrative) parameter setting.Need know which port can obtain BTSC_BLER (base station transceiver BLER (block error rate)) at analyzes, need simultaneously to understand and how in message, to decode BTSC_BLER, also want the artificial BLER that constantly sets with OM to compare, this needs the tester to have enough knowledge and experiences to select port message and decoding, and repeats constantly to compare.
2, have a large amount of tests to add up data and find out Changing Pattern, the data of utilizing each port directly to provide are more at random, can not intuitively reflect Changing Pattern, need a large amount of complicate statisticses, waste time and energy, and efficient is very low.For example: when verifying the downlink power control of multiple terminals, need maximum tatic range, relative dynamic scope and the power of testing base station transmitting power whether effectively to adjust etc., need on protocol analyzer, detect every measurement report, find out needed data (base station transmitting power BS Power), and write down these data in order.Utilize these data to find out the maximum tatic range of downlink power control, relative dynamic scope then, search downlink power control and whether can adjust to certain effective coverage automatically.This may relate to hundreds of bar measurement report, but also will judge that this measurement report belongs to the row operation of going forward side by side of which terminal, and analysis efficiency is very low.
When 3, verifying some algorithm, need carry out a large amount of relevances according to result data and calculate, each step mistake in computation all can cause decisive influence to test result, and since calculation of complex, the artificial very difficult accuracy that guarantees.For example: in the three carrier frequency DCA algorithms, better simply test in the selection of carrier frequency priority: the tester need divide into groups to the different carrier time slot at different business, obtains to unite priority behind the priority value of each time slot and calculate in Abis message: the associating priority value of choosing this service groups maximum on each carrier wave; The associating priority value of the maximum that each carrier wave of comparison is chosen; Value maximum in each carrier wave is compared with the value of maximum in all carrier waves, ratio is compared with specific OM parameter determine that certain carrier wave can distribute; Calculate carrier wave associating priority then, determine to select which carrier wave; If selected unique carrier wave, to judge at first then which time slot has passed through SIR (signal-to-jamming ratio) access control, in the time slot that has passed through, select the up and descending time slot of greatest priority then; Select unique carrier wave if fail, then need at first to add up BRU (code channel) resource of current each current free time of carrier wave, select then that the carrier wave of minimum of resources distributes, select the up and descending time slot of greatest priority then.The test of such layering association, a large amount of association judgements and data extract are difficult to make the tester to finish test like clockwork.

Step 701: obtain the measurement data of system's distinct interface respectively, comprising:
(1) from the message of wave point, obtains transmitting power, open loop power and the Timing Advance of base station when inserting at random;
(2) obtain object synchronization (SS_Target), user's synchronizing signal peak value (Peak_Target_Use), target signal to noise ratio (SIR_Target), user's signal to noise ratio the message between the inner module of base station;

In actual applications, can carry out the test of algorithms of different selectively according to the needs of actual measurement task, generate corresponding view, and according to the correctness of the view of test result and generation checking respective algorithms, its flow process can be finished the test of the following algorithm as shown in Figure 8:
1, to the test of power control algorithm
By searching the limiting value among the BS Power (base station transmitting power) in the measurement report, the difference of limiting value is that tatic range, this time slot maximum power user and the minimum power user's of downlink power control the difference of descending power is the relative dynamic scope.The history graphs of drawing BS Power can be found out the variation of base station transmitting power significantly, and last value should be stablized within limits, this variation tendency as can be seen from history curve.
The value of in measurement report, search SIR (signal to noise ratio), in TPC (message between the inner module of base station is obtained port), searching SIR_Target (target signal to noise ratio), generate the changes in contrast view of the two, if the variation tendency unanimity shows that then up inner-loop power control algorithm is correct.Manually import BLER (BLER (block error rate)) bound, this bound is provided with on the operational administrative platform, and its span is relevant with different types of service.In TPC, search BLER and form history graphs,,, then show the uplink external ring power control algorithmic error if BLER exceeds bound measuring value and the mark of searching the up BLER target zone that exceeds the bound permission on the BLER history curve.
For example: the checking uplink external ring power control:
From protocol analyzer, obtain BTSC_SIR (base station signal to noise ratio), UE_TrPwr (terminal transmission power), from intermodule message output port, obtain BTSC_BLER (base station transceiver BLER (block error rate)), add up interference, form data form:
Table 2:
| | BTSC_SIR | UE_TrPwr | |
| 0 | 11 | -95 | |
| 1 | 12 | -90 |
Increase if disturb, the BLER of BTSC can increase suddenly, slowly reduces then, is stabilized within some scopes; Reduce if disturb, the BLER of BTSC can reduce suddenly, slowly increases then, is stabilized at last within some scopes.Same BTSC_SIR, UE_TrPwr also have same variation tendency, have so just proved that the uplink external ring power control algorithm is effective.
The curve chart that forms according to tables of data as shown in Figure 9.By this figure, the outer shroud uplink power control is effective as can be seen.
2, to the test of synchronized algorithm
In measurement report, search Start, Peak, the End of SS (terminal synchronizes) in CHNRD (channel request) message, calculate adjusting values and with the contrast of actual adjusted value.The result of contrast is no more than 1, shows that then open loop is correct synchronously.Actual adjusted value provides in CHNAK (channel activates response) message, and theoretical adjusted value calculates by following rule:
1) if Peak_RACH-SS_Target_TS (DPCH)＞0, then
SS_update_DPCH＝Min{Start_RACH，(Peak_RACH-SS_Target_TS
DPCH)}
2) if Peak_RACH-SS_Target_TS (DPCH)＜0, then
Above in 2 formulas, the implication of each parametric representation is as follows:
SS_update_DPCH: synchronous adjusted value;
Start_RACH: the starting point of pulse signal RACH in the detection window;
Peak_RACH: the peak value of pulse signal RACH in the detection window;
End_RACH: the terminal point of pulse signal RACH in the detection window;
SS_Target_TS
DPCH: the synchronous desired value of pulse signal in the detection window;
WL_End_Position
DPCH: the final position that is detection window.
In measurement report, search SS_Target (object synchronization) value of SS in the CHNRD message, in TPC, search Peak_Target_Use (user's synchronizing signal peak value) value, the history curve of the SS_Target that draws, Peak_Target_Use.If the value of Peak_Target_Use surpasses 1 than SS_Target, show that then closed loop is incorrect synchronously.
3, the dynamic channel time slot is selected and is distributed
(i represents time slot to find the priority P i of each time slot of carrier wave in the RFTSP of TXT (indication of Radio Link time slot priority update) message, its value from 0 to 7), calculate the priority of time slot grouping, judge the carrier wave that participates in grouping, calculate carrier wave associating priority, determine that according to Pi the traffic branch is on the time slot of limit priority.
Be exemplified below: the channel in the checking dynamic channel allocation selects then algorithm (under the situation that 3 phones insert, judging whether the distribution of last phone meets rule).
Seek the 3rd MOC (moving to the calling of fixed network) according to the data that protocol analyzer obtains, and extract the carrier wave distributed and the information of time slot, obtain last MOC institute distributed time slot, obtain some other necessary information, obtain following information by the OM database:
BCCHIDLETHRESHOLD=100 (bcch carrier is not participated in the distribution);
It is 0.7 that OM parameter setting carrier wave is selected parameter value;
All time slots all are in normal operating conditions;
Have two phones to be distributed on the carrier wave 2, the 3rd phone is distributed on the carrier wave 1;
The time slot priority of two non-BCCH (Broadcast Control Channel) carrier wave is as shown in the table:
Table 3:
| TS1 | TS2 | TS3 | TS4 | TS5 | TS6 | |
| Carrier wave 1 (C1) | 1 | 0.84 | 0.84 | 1 | 0.84 | 0.84 |
| Carrier wave 2 (C2) | 0.89 | 0.89 | 0.89 | 0.89 | 0.89 | 0.89 |
Corresponding voice service is carried out time slot and is grouped as follows shown in the table:
Table 4:
| TS1/ TS4 | TS1/ TS5 | TS1/ TS6 | TS2/ TS4 | TS2/ TS5 | TS2/ TS6 | TS3/ TS5 | TS3/ TS6 | |
| C1 time |
1 | 0.84 | 0.84 | 0.84 | 0.71 | 0.71 | 0.71 | 0.71 |
| C2 time slot associating priority | 0.79 | 0.79 | 0.79 | 0.79 | 0.79 | 0.79 | 0.79 | 0.79 |
Maximum: C1=1, C2=0.79,0.79/1＞0.70, so two carrier waves are all participated in the distribution.
Calculate two carrier wave associating priority:
C1＝0.84*0.84*0.84*0.84*1*1＝0.50
C2＝0.89*0.89*0.89*0.89*0.89*0.89＝0.50
So, also need to carry out minimum of resources and select (being about to new user is distributed on the less carrier wave of idling-resource).Find that by idle BRU is calculated last user should be distributed on the C2, actual test result is to be distributed on the C1, so these algorithm existing problems, it is wrong that the data of above-mentioned analytic process are shown the explanation algorithm.
4, to the test of handoff algorithms
Calculate the priority of adjacent sub-district, computing formula is as follows:
PRO_NCell(n)＝{RSCP_DWPTS_NCELL(n)-(BTSC_TSCP_DWPTS-(BTSC_TSCP_DCH-UE_RSCP_DCH))
+min(UE_TSCP_MAX_SCELL，P)-min(UE_TSCP_MAX_NCELL(n)，P)}-hoMargin(n)
Wherein,
RSCP_DWPTS_NCELL (n): the receiving code power of adjacent cell downlink pilot time slot;
BTSC_TSCP_DWPTS: the delivering power of base station down pilot time slot;
BTSC_TSCP_DCH: the delivering power of base station dedicated channel;
UE_RSCP_DCH: the receiving code power of terminal-specific channel;
UE_TSCP_MAX_SCELL: the maximum transmission power of terminal in this sub-district;
P: terminal maximum transmission power;
HoMargin (n): be to stop the threshold value that switches to adjacent sub-district, on the operational administrative platform, be provided with.
Read the adjacent cell list that switches in the indication, list prioritization and actual adjacent cell list, the switching type according to switching in the indication reads the correlation in the measurement report, judges whether to satisfy switching condition according to formula.According to different switching types, different switching formula is arranged, be expressed as follows respectively:
1.Quality Intercell Handover (switching of minizone quality):
BTSC_BER＞hoLowerThresholdQualUL
BTSC_RSCP≤hoThresholdRSCPULintra
Wherein:
HoLowerThresholdQualUL is that the up quality that OM is provided with is switched minimum threshold;
HoThresholdRSCPULintra switches the RSCP thresholding between the uplink cells that is provided with of OM.
2.Quality Intracell Handover (quality is switched in the sub-district):
BTSC_BER＞hoLowerThresholdQualUL
BTSC_RSCP＞hoThresholdRSCPULintra
Wherein:
