Embodiment
At problems of the prior art, the present invention propose a kind of by to the parameter relevant with the radio link failure incident and with rebuliding the wireless connections incident relevant parameter analyze, effectively detect the scheme of the occurrence cause of various radio link failure incidents.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, scheme of the present invention is described in further detail.
Fig. 1 is the flow chart of the inventive method embodiment.As shown in Figure 1, may further comprise the steps:
Step 11: the terminal and first Serving cell are set up wireless connections, when the radio link failure incident takes place, obtain and parameter that preservation is relevant with the radio link failure incident.
According to introduction before as can be known, when terminal and first Serving cell are set up wireless connections and carried out in the process of a certain business, because a variety of causes, such as handoff parameter improper, signal is set and covers cavity, inter-cell signal interference and signal rapid fading etc., may cause the generation of radio link failure incident.In the present embodiment, in case the radio link failure incident takes place, then terminal can be initiated the wireless signal measuring process immediately one time, the content of measuring comprises: the Reference Signal Received Power (RSRP of first Serving cell and adjacent sub-district thereof, Reference Signal Receiving Power) value etc., how to determine which sub-district is that the adjacent sub-district of first Serving cell is a prior art, the RSRP value is used to reflect the signal power of sub-district; Afterwards, each RSRP value that terminal will measure, the time of origin of radio link failure incident and some other parameters, such as the ID and the cell type of first Serving cell, and the preservations such as historical information of terminal are got off.The ID of first Serving cell and cell type, and the obtain manner of the historical information of terminal etc. is similarly prior art, wherein, cell type is used to size that illustrates first Serving cell etc., the historical information of terminal is used for illustrating that terminal in resident time of first Serving cell etc., can determine the translational speed of terminal by these two parameters.
Step 12: the terminal and second Serving cell rebulid wireless connections, and the information of being preserved is reported base station under second Serving cell.
After the radio link failure incident takes place, for original business can be proceeded, terminal needs again and a Serving cell, and promptly second Serving cell is set up wireless connections, second Serving cell may be identical with first Serving cell in the step 11, also may be different.Which sub-district is terminal select as second Serving cell and how to set up wireless connections etc. with second Serving cell and be prior art, repeats no more.
After the terminal and second Serving cell rebulid wireless connections, with the information of being preserved in the step 11, the historical information of each the RSRP value that promptly measures, the ID of first Serving cell and cell type, terminal, and the time of origin of radio link failure incident etc. reports the base station under second Serving cell.
Step 13: the base station under second Serving cell determines whether first Serving cell belongs to the sub-district of self administering, if, then execution in step 14, otherwise, information that terminal is preserved and the parameter relevant with rebuliding the wireless connections incident send to the base station under first Serving cell, then the base station execution in step 14 under first Serving cell.
In this step, base station under second Serving cell determines that at first whether the radio link failure incident is to take place in the sub-district under self administers, promptly the ID according to first Serving cell determines whether first Serving cell belongs to the scope of self administering, if, then execution in step 14, if not, then information that the terminal that receives is preserved and the parameter relevant with rebuliding the wireless connections incident comprise that time of rebuliding wireless connections and ID of second Serving cell etc. send to the base station under first Serving cell.In actual applications, the base station under second Serving cell can inquire the base station under first Serving cell according to the ID of the first known Serving cell.
Step 14: the occurrence cause that information of preserving according to terminal and the parameter relevant with rebuliding the wireless connections incident are determined the radio link failure incident.
Fig. 2 is the realization flow figure of the step 14 among the inventive method embodiment.As shown in Figure 2, may further comprise the steps:
Step 21: according to the cell type of first Serving cell and the historical record of terminal, determine the translational speed of terminal, and whether the translational speed of definite terminal is less than predefined first threshold S_max_speed, if, then execution in step 22, otherwise, process ends.
When moving velocity of terminal is too fast; do not cover problems such as cavity, inter-cell signal interference and signal rapid fading even do not exist handoff parameter that improper, signal is set; also may cause the generation of radio link failure incident; and this situation is not within the protection range of scheme of the present invention; therefore in this step; if the translational speed of the terminal of determining more than or equal to S_max_speed, then need not to carry out subsequent treatment, direct process ends.
Step 22: whether the difference of time of origin of determining to rebulid time of wireless connections and radio link failure incident greater than the predefined second threshold value T_min_cov, if then execution in step 23, otherwise, execution in step 24.
Step 23: determine whether to exist in the RSRP value of first Serving cell and adjacent sub-district thereof RSRP value greater than predefined the 3rd threshold value P_low_thres, if, the occurrence cause of then determining the radio link failure incident is an inter-cell signal interference, process ends, otherwise, the occurrence cause of determining the radio link failure incident is that signal covers cavity, process ends.
Step 24: determine according to the ID of first Serving cell and the ID of second Serving cell whether first Serving cell and second Serving cell are same sub-district, if, the occurrence cause of then determining the radio link failure incident is the signal rapid fading, process ends, otherwise, it is improper that the occurrence cause of determining the radio link failure incident is that handoff parameter is provided with, process ends.
The concrete value of above-mentioned each threshold value can be decided according to the actual requirements.
As can be seen, by flow process shown in Figure 2, can detect the occurrence cause of this radio link failure incident.But, consider the randomness incident that may have various bursts in actual applications, independent one-time detection the possibility of result is inaccurate, therefore, follow-uply also can further carry out following processing: after determining the occurrence cause of radio link failure incident each time, the counter of the occurrence cause correspondence of this radio link failure incident is added one; The value of each counter accounts for the ratio of the total value of all counters in the statistics scheduled duration (can periodically carry out), obtain four statisticses, determine that respectively whether each statistics is greater than each self-corresponding threshold value, if then the occurrence cause according to its corresponding radio link failure incident carries out system optimization.That is to say, if the frequency of occurrences of the occurrence cause of a certain radio link failure incident surpasses threshold value, so then think to have the problem corresponding really in the current system, correspondingly with it, carry out system optimization, to prevent the further generation of radio link failure incident.The value of the threshold value of the occurrence cause correspondence of each radio link failure incident can be identical, also can be different, and the concrete value of each threshold value can be decided according to the actual requirements.
