Embodiment
Low for solving definite efficiency of crossing covering in the community of prior art existence, and accuracy rate is lower problem also, it is a kind of based on measurement report (MR that the embodiment of the present invention provides, Measurement Report) determine time advance value, and determine that according to definite time advance value community crosses the scheme of covering.In this scheme, consider that the time advance value etc. that can comprise UE in the MR that the physical layer of TD-LTE system reports embodies Target cell and whether crosses the data that cover, therefore the MR that gives chapter and verse determines time advance value, and the time advance value based on definite, determine whether Target cell existed covering, thereby avoided depending on the mode that network optimization engineer adopts manual type site inspection and determined time advance value, and it is lower to cause community to cross definite efficiency of covering, and the larger problem of the stock number expending.
Below in conjunction with accompanying drawing, definite scheme of covering is crossed in the community that describing the embodiment of the present invention in detail provides.
First, a kind of definite method that the embodiment of the present invention provides community as shown in Figure 1 to cross covering, the specific implementation flow process of the method comprises the steps:
Step 11, obtains the measurement report for Target cell, and from the measurement report obtaining, resolves and obtain time advance value and report parameter;
In the embodiment of the present invention, 3GPP official hour shifts to an earlier date value interval and time advance value reports the corresponding relation of parameter as shown in table 1:
Table 1:
Step 12, time advance value based on default reports the corresponding relation of parameter and measurement report statistical parameter, the time advance value obtaining according to parsing reports parameter, determines respectively the number that reports parameter corresponding to the time advance value of different measuring report statistics parameter;
Wherein, measurement report statistical parameter is for representing that time advance value reports the parameter of the number of parameter.
Step 13, the corresponding relation in the measurement report statistical parameter based on setting in advance and time advance value interval, corresponding stored time advance value is interval and corresponding to the time advance value of different measuring report statistics parameter, report the number of parameter;
In the embodiment of the present invention, measurement report statistical parameter, time advance value interval and time advance value report the corresponding relation of parameter can be as shown in table 2:
Table 2:
In table 2, MR.Tadv.00 ~ MR.Tadv.47 can be called the first measurement report statistical parameter ~ 48 measurement report statistical value successively.
The partition strategy in the corresponding time advance value of the measurement report statistical parameter interval in table 2 can be: the time advance value that is less than 10 time slots is divided into a time advance value interval; And
Right open interval is closed in the left side consisting of 10 time slots and 200 time slots and divide, obtain the time advance value interval that 19 interval ranges are not more than 10 time slots;
Right open interval is closed in the left side consisting of 200 time slots and 1000 time slots and divide, obtain the time advance value interval that 20 interval ranges are not more than 40 time slots;
Right open interval is closed in the left side consisting of 1000 time slots and 2000 time slots and divide, obtain the time advance value interval that 5 interval ranges are not more than 200 time slots;
Right open interval is closed in the left side consisting of 2000 time slots and 4096 time slots and divide, obtain the time advance value interval that 2 interval ranges are not more than 1048 time slots; And
The time advance value that is more than or equal to 4096 time slots is divided into a time advance value interval.
According to above-mentioned partition strategy, divide 48 time advance value intervals that obtain and refer to table 3.
Table 3:
Except above-mentioned partition strategy, the embodiment of the present invention also can adopt other partition strategies to divide time advance value interval.
Step 14, the time advance value based on corresponding stored report the number of parameter and time advance value interval, determine that the time advance value that shifts to an earlier date value interval corresponding to the fixed time reports the number of parameter;
It should be noted that, in the embodiment of the present invention, also can perform step the storage operation described in 13, but can be directly based on 12 numbers that statistics obtains of execution step, carry out and determine that the time advance value that shifts to an earlier date value interval corresponding to the fixed time reports the operation of the number of parameter.
It can be according to the setting coverage of Target cell or optimization demand, to arrange in advance that fixed time described here shifts to an earlier date value interval.Such as, fixed time shifts to an earlier date value interval and can be set to meet: the time advance value comprising is all less than (or being not more than) for the time advance value of the UE in this setting coverage, or also can be set to meet: the time advance value comprising is all greater than (or being not less than) for the time advance value of the UE in this setting coverage.
Step 15, determines that the time advance value that shifts to an earlier date value interval corresponding to the fixed time reports the number of parameter and resolves and obtain the ratio that time advance value reports total number of parameter from measurement report;
In the embodiment of the present invention, when the fixed time shifts to an earlier date value interval and is set to meet: when the time advance value comprising is all greater than for the time advance value of the UE in the setting coverage in Target cell, this ratio is larger, UE outside setting coverage is more in explanation, thereby Target cell existed the possibility covering larger, otherwise illustrate that Target cell existed the possibility covering less.
When the fixed time shifts to an earlier date value interval and is set to meet: when the time advance value comprising is all less than for the time advance value of the UE outside the setting coverage in Target cell, this ratio is larger, UE in setting coverage is more in explanation, thereby Target cell existed the possibility covering less, otherwise illustrate that Target cell existed the possibility covering larger.
Step 16, according to by execution step 15, definite ratio determines whether Target cell existed covering.
In the embodiment of the present invention, if the fixed time shifts to an earlier date, value is interval to be met: the time advance value comprising is all greater than the time advance value for the UE in the setting coverage in Target cell; The method can further include: more above-mentioned ratio and the first preset ratio threshold value; And when comparing this ratio and be greater than the first preset ratio threshold value, according to this ratio indication base station, carry out the network optimization scheme for Target cell.Such as, can directly this ratio be offered to base station, indicate it according to this ratio, to determine and carry out corresponding network optimization scheme; Also can determine after network optimization scheme according to this ratio, then network optimization scheme is offered to base station, this network optimization scheme is carried out in indication base station.
Due to the mode than artificial definite time advance value, the mode of determining time advance value according to measurement report is more objective, accurate, and efficiency is higher, therefore than prior art, the scheme that adopts the embodiment of the present invention to provide can improve definite efficiency and the accuracy rate that covering is crossed in community greatly.
It should be noted that, the executive agent of the said method that the embodiment of the present invention provides can be, but not limited to be arranged on the equipment (being called the equipment that MR generates counter as arranged one) in base station or is arranged on the equipment (being called the equipment that MR generates counter as arranged one) in OMC.
Below based on a concrete execution mode, describe this scheme that the embodiment of the present invention provides application flow in practice in detail.
In this embodiment, by gather the mode of MR at the whole network, add up the Timing Advance that UE in Target cell arrives antenna for base station, thereby provide more objective and foundation accurately for determining that the community of Target cell is crossed to cover.
This embodiment is usingd TD-LTE system as its application scenarios.For TD-LTE system, the data that comprise in the MR reporting based on physical layer rich, MR can be used for triggering TD-LTE system Radio Resource control sublayer and complete events such as community selection/reselection and switching, also Operation and Maintenance foundation that can be using it as TD-LTE system, or as the running state analysis foundation of TD-LTE system.In this embodiment, consider the time advance value that includes UE in MR, thereby propose by (the OMC of operation maintenance center, Operations & Maintenance Center) collect MR, and by the time advance value comprising in MR, definite method of covering is crossed in the community that realizing the embodiment of the present invention provides.
The said method providing in order to implement the embodiment of the present invention can increase one newly and be called the device of " covering determining device is crossed in community ", or cross by make it possess community to the transformation of OMC existing equipment the function that covering determining device realizes in OMC.In addition, a MR can also be set and generate counter, this counter can be arranged in base station, also can be arranged in OMC.Comprising community crosses and covers a kind of system configuration schematic diagram that determining device and MR generate counter as shown in Figure 2 a.The function that the function of MR generation counter is crossed covering determining device with community combines, and definite method of covering is crossed in the community that can intactly realize the embodiment of the present invention provides.System configuration based on shown in Fig. 2 a, the specific implementation that definite method of covering is crossed in community comprises following step as shown in Figure 2 b:
According to 3GPP regulation, base station can periodically gather the measurement data of the time advance value of each UE (such as take 5s as the cycle).For example, suppose that the some time inscribes, the time advance value TADV of UE in base station measurement Target cell is 8Ts, the time advance value by shown in table 1 is interval shifts to an earlier date with 3GPP official hour the corresponding relation that value reports parameter, and can judging the corresponding time advance value of 8Ts, to report parameter be TIME_ADVANCE_0004; After 5s, the time advance value TADV=10Ts of UE, and according to table 1, determining the corresponding time advance value of 10Ts, to report parameter be TIME_ADVANCE_0005; After 5s, if base station measures the time advance value TADV=11Ts that UE arrives base station again.
MR, except coming from UE, can also come from physical layer and the rlc layer of base station, and MR also can calculate generation in RRM process.Therefore,, in the embodiment of the present invention, the MR that base station obtains also can come from other equipment except base station, that the MR that comprises time advance value can be provided.
Such as according to table 1, can be by base station by the mode to the collection of UE reporting information, realize according to the reporting information gathering and shift to an earlier date value computing time; Or base station also can determine time advance value by shifting to an earlier date the mode of value direct computing time, and in follow-up step, report parameter to send to OMC corresponding measurement report statistical parameter or corresponding time advance value.Wherein, Timing Advance computational methods can be with reference to 3GPP36.214V10.0.0, its concrete norm is: Class1: TADV=(eNB Rx-Tx timedifference)+(UE Rx – Tx time difference), and wherein the eNB Rx – Tx time difference is corresponding to the identical UE of report UE Rx – Tx time difference; Type 2:TADV=(eNB Rx – Tx time difference), wherein the eNB Rx – Tx time difference is received the uplink radio frame that comprises PRACH from each UE corresponding to eNB.
The partition strategy in the corresponding time advance value of the measurement report statistical parameter interval in table 2 can be, but not limited to for: the time advance value that is less than 10 time slots is divided into time advance value interval; And right open interval is closed in the left side consisting of 10 time slots and 200 time slots and divide, obtain the time advance value interval that 19 interval ranges are not more than 10 time slots; Right open interval is closed in the left side consisting of 200 time slots and 1000 time slots and divide, obtain the time advance value interval that 20 interval ranges are not more than 40 time slots; Right open interval is closed in the left side consisting of 1000 time slots and 2000 time slots and divide, obtain the time advance value interval that 5 interval ranges are not more than 200 time slots; Right open interval is closed in the left side consisting of 2000 time slots and 4096 time slots and divide, obtain the time advance value interval that 2 interval ranges are not more than 1048 time slots; And it is interval that the time advance value that is more than or equal to 4096 time slots is divided into a time advance value.
Based on table 3 and the time advance value that the UE that supposed sends, report parameter above, MR generates counter and can determine: for this Target cell, the corresponding time advance value of MR.Tadv.00 number is 2, the corresponding time advance value of MR.Tadv.01 number is 1, and the corresponding time advance value of other measurement report statistical parameters number is 0.
Optionally, when MR generation counter is while being arranged in OMC, the result shown in table 2 can draw by carrying out the operation of similar above-mentioned steps 22 by the MR generation counter in OMC, the now base station MR forwarding that only execution sends UE and the operation of OMC.
Owing to determining in order to reach whether community existed the object covering, OMC can only be known the corresponding relation in measurement report statistical parameter and time advance value interval, therefore, base station also can only provide result as shown in table 3 to OMC, thereby with respect to table 2 is provided, can save a part of transfer resource.
By carrying out above-mentioned steps 21 ~ 23, realized corresponding stored measurement report statistical parameter and time advance value interval in OMC, the corresponding relation based on both, can further be realized and be crossed determining of covering to the community of Target cell by following step.
It should be noted that, although directly report the corresponding relation in parameter and time advance value interval according to the time advance value shown in table 1, also can determine the number that time advance value in each time advance value interval reports parameter, yet, such mode need to repeatedly determine that time advance value for Target cell reports under the scene of number of parameter, all need respectively the fixed time to be shifted to an earlier date to the interval corresponding time advance value of each time advance value of containing in value interval reports the number of parameter again to determine one by one at every turn, thereby can expend more processing resource.And the measurement report statistical parameter shown in employing table 2 and the corresponding relation in time advance value interval, because generally can being greater than corresponding to each time advance value, the time advance value interval corresponding to measurement report statistical parameter report the time advance value of parameter interval, therefore under above-mentioned scene, based on table 2, can reduce to carry out and determine that time advance value reports the number of times of the operation of parameter, thereby can promptly determine that the time advance value that shifts to an earlier date value interval corresponding to the fixed time reports number of parameters, thereby greatly improve treatment effeciency.
In present embodiment, suppose that it is [x, y] that this fixed time shifts to an earlier date value interval, has following formula to set up:
In the fixed time, shift to an earlier date value interval time advance value number based on MR, obtain for the ratio=(MR.TADV.p+MR.TADV.p in the total number of time advance value of Target cell
+ 1+ ... + MR.TADV.q)/(MR.TADV.00+MR.TADV.01+ ... + MR.TADV.47)
Wherein, the arrangement sequence number that p, q are the corresponding measurement report statistical parameter in interval that comprises [x, y] and interval size and form close to time advance value [x, y], that obtained by division interval.Such as, take table 2 as example, if meet the fixed time of above-mentioned hypothesis shift to an earlier date value interval for [190,1000), according to the above-mentioned restriction about p, q, can determine p=19, q=39.
Such as, if suppose, the fixed time shifts to an earlier date value interval and arranges satisfied: the time advance value comprising is all greater than the time advance value for the UE in the setting coverage in Target cell, when comparative result is: by perform step 24 and definite ratio value is greater than preset ratio threshold value a%(a can set according to the practical operation situation of Target cell network) time, can determine that Target cell existed covering; Otherwise, can determine that Target cell did not exist covering.
For having the community covering, and it is generally acknowledged, to cause covering reason be mainly that part base station antenna height surpasses peripheral base station antenna height, because radio wave diffraction refraction etc. propagates into place far away.Supposing finally to judge covering is because certain antenna for base station causes, and can adjust antenna azimuth, or reduces angle of declination, or reduction base station transmitting power, if possible, in the situation that meeting current covering, suitably reduce antenna height, thereby avoid or reduced coverage condition.

Due to the mode than artificial definite time advance value, the mode of determining time advance value according to measurement report is more objective, accurate, and efficiency is higher, therefore than prior art, above-mentioned execution mode can improve definite efficiency and the accuracy rate that covering is crossed in community greatly, and required resource is less.
In addition, first the embodiment of the present invention has also proposed for characterizing the concept of the measurement report statistical parameter of time advance value number, and defined corresponding relation as shown in table 2, thereby when improving network optimization result accuracy, also guaranteed higher treatment effeciency.
In prior art, TD-LTE is the MR acquisition scheme of neither one standard also, the degree of support that each equipment manufacturer gathers for MR differs, the network equipment lacks a reliable measuring means to the preparatory and integrality of the MR data that report, thereby the accuracy that relies on MR data to carry out Network Quality Analysis and Optimization Work cannot be guaranteed.And in the embodiment of the present invention, first the collection call format of a kind of MR has been proposed, unified span and the value unit of measurement report statistical parameter, with this standard each equipment manufacturer's MR gather form, realized and evaded the object that equipment is transformed repeatedly.
