Specific embodiment
Various embodiments of the invention are illustrated with reference to the accompanying drawing.These embodiments are only exemplary,
It is not limitation of the present invention.
It is analyzed first by actual example the problem of current thresholding configures.
Figure 1A to Fig. 1 C is the schematic diagram of a scenario for typically switching generation twice in succession.As shown in Figure 1A to Fig. 1 C, terminal
Equipment is successfully switched to Microcell (Pico cell) B (switching for the first time) from macrocell (Mcell) A first, then in quilt
Experience links failure before switching out Pico cell B (second of switching) again.According to existing mobile robustness optimization
(MRO, Mobility Robustness Optimization) testing mechanism, Pico cell B are receiving Radio Link Failure
After indicating (RLF Indication) message, mobile robustness optimization (MRO, Mobility are carried out to the link failure
Robustness Optimization) detection.If the preconfigured thresholding (Tstore_UE_ used in the detection
Cntxt it is improper) to configure, it is most likely that connects link failure and first time switching, to judge that the link is unsuccessfully
' switching is too early ' or ' being switched to wrong cell '.In fact, link failure with switch for the second time related, should be judged as ' switching
Too late '.Failure detection method in current mechanism is illustrated by taking scene shown in figure 1A as an example below.
Fig. 1 D is failure detection method flow diagram in current mechanism.As shown in figure iD, comprising the following steps:
Base station A sends switching command (Handover Command) to terminal device UE (see step 101)；The UE is successfully cut
Base station B is changed to (see step 102)；Radio Link Failure (RLF) occurs for the UE, at this point, sending switching command from base station A to the UE
The time that RLF occurs to the UE is T1 (see step 103)；
The UE is attached reconstruction or connection creates successfully, for example, the cell that reconstruction or newly-built community are base station A is (see step
It is rapid 104) to receive the RLF report (Report) of UE transmission, it include time T1 in the RLF Report (see step 105)；Base station
A sends RLF to base station B and indicates (Indication) message, includes the RLF report in the RLF instruction message (see step 106)；
Base station B detects link failure reason (see step 107)；It is to switch too early or be switched to the cell of mistake in link failure reason
When, Xiang Jizhan A sends handover report message and (corrects mistake see step 108) and by base station A (see step 109)；It is lost in link
When losing reason to switch too late, then mistake is corrected (see step 110) by base station B.
In step 107, its thresholding (T, such as Tstore_UE_cntxt) is compared by base station B with T1, is greater than T in T1
When, link failure is determined the reason is that switching too late；When T1 is less than T, determine that switching is too early or is switched to wrong cell.
Under the scene shown in Fig. 1 D, if thresholding T setting is excessive, in step 107, T1 may always be less than T,
In this way, link failure reason is always judged as switching too early or being switched to the cell of mistake.If leading to link failure at this time
True cause is that switching is too late, then can then draw the wrong conclusion according to current mechanism.
Therefore, the embodiment of the present invention provides a kind of parameter optimization method, device and communication system, can be to preset thresholding
It optimizes, avoids unsuccessfully judging by accident caused by thresholding is improper as far as possible, so that more accurate mobile robustness optimization is obtained, and
Promote network performance.It is carried out below in conjunction with attached drawing, by taking MRO detection process as an example to the parameter optimization method of the embodiment of the present invention
