Wherein, described MeNB is according to described the first measurement result and described the second measurement result, carrying out measurement result processes while operating, can be according to described the first measurement result and described the second measurement result, to DC (Dual Connectivity, dual link) adjust, and/or described the first measurement result and described the second measurement result are reported, so that receive that the entity of measurement result carries out Performance Detection according to described the first measurement result and described the second measurement result.

Be introduced respectively below.

Mode of operation one, MeNB, according to described the first measurement result and described the second measurement result, adjust DC.

Concrete, if needed, the allocation proportion of MeNB capable of regulating AMBR (Aggregate Maximum Bit Rate) between two base stations; Or under carrying separation case, MeNB adjusts the shunt ratio between two base stations.MeNB also can judge current DC performance according to the above results, if poor before the ratio that the second measurement result shows expection or not shunting, MeNB can not carry out DC.

Mode of operation two, MeNB report described the first measurement result and described the second measurement result, so that receive that the entity of measurement result carries out Performance Detection according to described the first measurement result and described the second measurement result.

In force, described the first measurement result and described the second measurement result can be measurement result (the i.e. not process calculating that original L2 measures, but measure the result directly obtaining), can be also the measurement result (through measuring the result directly obtaining) that final L2 measures.Describe respectively below.

Situation one, described the first measurement result and described the second measurement result are the measurement results that final L2 measures.

Concrete, described the first measurement result and described the second measurement result that described MeNB measures same time section merge processing, and the measurement result after processing is reported; Or

Preferably, if for L2 be measured as for the measurement of scheduled IP throughput or for the measurement of scheduled IP throughput for MDT, described MeNB is added the measurement result measuring in described MeNB and described SeNB same time section; Or

If for being measured as for downlink data packet delay and/or data loss rate of L2, described MeNB is added the measurement result measuring in described MeNB and described SeNB same time section to be averaged.。

Situation two, described the first measurement result and described the second measurement result are the measurement result that original L2 measures.

Concrete, described MeNB merges processing by described the first measurement result and described the second measurement result, the measurement result merging after processing is converted to the measurement result that final L2 measures, and reports; Or

Preferably, described MeNB is added the identical measurement result measuring in described MeNB and described SeNB same time section.

For situation two, if MeNB measures by L2 the measurement result merging processing that original L2 measures,, when the measurement result that the L2 after processing is measured converts the measurement result of final L2 measurement to, continue to use existing L2 and measure computing formula, calculate final measurement result and report again.Also not identical according to measuring amount different formulas, concrete formula can be referring to TS36.314.

For example, for scheduled IP throughput for MDT, the computing formula of this measuring amount is:

In time T, the computing formula of the descending Scheduled IP throughput for MDT of statistics is as follows:

If Σ ThpTimeDl > 0,

Scheduled IP throughput = \frac{ΣThpVolDl}{ΣThpTimeDl} x 1000 [kbits / s]

If Σ is ThpTimeDl=0, Scheduled IP throughput=0[kbits/s]

For small data packets (all data of this packet can send by mixed once HARQ (HARQ)), ThpTimeDl=0, otherwise ThpTimeDl=T1-T2[ms], parameters is defined as follows:

The measurement result that MeNB measures according to the original L2 under SeNB (comprising transmission data volume size ThpTimeDl, transmission initial time T2, transmission termination time T1 etc. in the corresponding time period), and the measurement result that the original L2 oneself obtaining measures (comprises the big or small ThpTimeDl of the transmission data volume of correspondence in the section time, sends initial time T2 ', send termination time T1 ' etc.), just can obtain data volume size and the actual transmission required time of these data of sending accurately.

As shown in Figure 2 B, the each transmitted data amount of MeNB is V, and the transmission time is T, being specially first interval time of measurement is that transmitted data amount is V, transmission time started t1, termination time t2, second interval time of measurement is that transmitted data amount is V, transmission time started t4, termination time t5; The each transmitted data amount of SeNB is also V, and the transmission time is 2T, and being specially first interval time of measurement is that transmitted data amount is V, transmission time started t1, termination time t3, second interval time of measurement is that transmitted data amount is V, transmission time started t5, termination time t6.MeNB receives after raw measurement data, and the same measurement that same same time obtains is added, and according to computing formula, can draw:

The scheduled IP throughput for MDT measuring in interval for first is 2V/2T=V/T;

For second scheduled IP throughput for MDT measuring in interval, be 2V/3T.

As can be seen here, because MeNB and SeNB may send data simultaneously, corresponding measurement result only need to be calculated once the time period of this part stack so.So it is more accurate that situation two is compared situation one, but signaling is more, MeNB processes more complicated.

For situation two, MeNB can also configure the measurement result that described SeNB reports original L2 to measure.

The embodiment of the present invention triggers the entity difference that MeNB measures, and receives that the entity of measurement result also may be different.The entity of measuring such as triggering MeNB is MDT entity, and MeNB need to report MDT entity; The entity that triggering MeNB measures is OAM entity, and MeNB need to report OAM entity.

Enumerate again 3 examples below, the solution of the present invention is elaborated.

The schematic diagram of 3 examples below can be referring to Fig. 9.

Scheduled IP throughput during example 1:SCG (Secondary Cell Group, auxiliary cell set) carrying processes.

Under object UE, QCI (QoS class Identifier, QoS Class Identifier) is non-GBR (non-ensured bit rate carrying) carrying of i and j, is used as SCG carrying and is diverted to SeNB, and this carries corresponding radio protocol stack all at SeNB.MeNB wants to measure by L2, the performance of SCG carrying after understanding use dual link, and MeNB wants to obtain the scheduled IP throughput performance under now SCG carrying.

Step 1:MeNB triggers SeNB by X2 interface and carries out L2 measurement, in the middle of comprise the L2 measuring amount that needs are collected, i.e. scheduled IP throughput for DL/UL (downlink/uplink), QCI=i, j.

Optionally, carry and measure time started t1, allow SeNB constantly start to collect at t1 the scheduled IP throughput result that QCI is the SCG carrying of i and j.

If MeNB and SeNB are asynchronous, SeNB basis and the time difference of MeNB and the measurement time started t1 receiving, determine and measure the time started.

Step 2:SeNB triggers according to MeNB, carries out relevant L2 measure and collect for the SCG carrying of object UE, because SCG carries corresponding radio protocol stack all at SeNB, can continue to use existing LTE L2 and measure definition;

Meanwhile, MeNB also carries out scheduled IP throughput measurement for other carryings of object UE.

Step 3:SeNB reports the L2 measurement result of collection to MeNB according to the triggering of MeNB.

Another kind of mode is, MeNB configure report cycle, (such as being that SeNB configures report cycle in step 1), SeNB is according to report cycle, and the cycle reports the L2 measurement result of collection to MeNB.

If in step 1, MeNB configuration SeNB reports original scheduled IP throughput to collect result, and SeNB collects data report to MeNB by scheduled IP throughput original in each time period.

Step 4:MeNB is according to the L2 measurement result of the SeNB receiving, and the L2 measurement result of self, judges the performance of current use DC (Dual Connectivity, dual link) and adjusts.

Such as, MeNB, according to the L2 measurement result of MeNB and SeNB, adjusts AMBR in the allocation proportion at place, two base stations, or the performance boost situation after judgement use DC, and determines whether still to continue DC.

In force, MeNB also can be by the L2 measurement result of the SeNB side of receiving, and the L2 measurement result of self, and direct one reports OAM (Operations and Maintenance, operation and maintenance), for OAM Performance Detection.If report OAM, a kind of preferably mode is: MeNB gives the correct time in measurement result, SCG is carried to corresponding L2 measurement result and by sign, distinguished, so which L2 measurement result OAM can determine, for SCG, carries; Further, can also carry corresponding SeNB sign.

If what MeNB received is raw measurement data, the original scheduled IP throughput that MeNB also can measure the SeNB receiving collects data, the original scheduled IP throughput measuring with MeNB collects Data Integration, utilize existing scheduled IP throughput computing formula, draw the scheduled IP throughput measurement result under SCG carrying final under each time period, report OAM, for OAM, analyze.

During embodiment 2:Split carrying, scheduled IP throughput for MDT (Minimization of drive-tests, minimum road test) processes.

The DL scheduled IP throughput result that the QCI that need to collect object UE is i, the split that is carried as that this QCI is corresponding carries, PDCP (Packet Data Convergence Protocol, packet data polymerized agreement) at MeNB place, MeNB and SeNB respectively have corresponding RLC (Radio Link Control, wireless link is controlled)/MAC (Medium Access Control; Media access control).

Step 1:MeNB triggers SeNB by X2 interface and carries out L2 measurement, in the middle of comprise the L2 measuring amount that needs are collected, i.e. DL scheduled IP throughput for MDT, QCI=i.

Optionally, carry and measure time started t1 and collection interval T, allow SeNB constantly start at t1, collecting QCI is the DL scheduled IP throughput for MDT result of the split carrying of i, and interval T is collected again.

Optionally, MeNB can configure SeNB and report original DL scheduled IP throughput for MDT collection result.

Step 2:SeNB triggers according to MeNB, carries out relevant L2 measure and collect for the split carrying of object UE.Simultaneously, MeNB also carries out scheduled IP throughput for MDT for the split carrying of object UE and measures, now MeNB, when statistics PDCP SDU bag, need to will send to PDCP SDU (Service Data Unit, the service data unit) bag of SeNB to get rid of.

Under split carrying, PDCP layer is at MeNB, when SeNB carries out DL scheduled IP throughput for MDT measurement, can be by reference point PDCP upper SAP (the Service Access Point of packet in measuring process, Service Access Point) move down, with RLC upper SAP, replace.

In the L2 measurement result that SeNB reports, comprise absolute time t1 (measuring the time started) and each L2 surveying record relative time constantly, for MeNB association MeNB and SeNB place L2 measurement result.

If in step 1, MeNB configuration SeNB reports original DL scheduled IP throughput for MDT to collect result, and SeNB collects data report to MeNB by DL scheduled IP throughput for MDT original in each time period.

Step 4:MeNB gathers the L2 measurement result of SeNB side and the L2 measurement result (will put MeNB and SeNB results added approximate time) of self, obtain the DL scheduled IP throughput for MDT measurement result of the QCI=i of this UE within certain a period of time, summarized results is informed to the collection entity of MDT, for its Performance Detection and analysis.

If what MeNB received is raw measurement data, the original DL scheduled IP throughput for MDT that MeNB also can measure the SeNB receiving collects data, the original DL scheduled IP throughput for MDT measuring with MeNB collects Data Integration, utilize existing DL scheduled IP throughput for MDT computing formula, draw the DL scheduled IP throughput for MDT measurement result under split carrying final under each time period, report OAM, for OAM, analyze.

MeNB also can utilize the L2 measurement result of the SeNB measurement of receiving, and the L2 measurement result of self measuring, and judges the performance of current use DC and adjusts.

DL packet delay (downlink packet time delay) during embodiment 3:Split carrying processes.

The carrying that QCI=i is corresponding is carried as split, and PDCP is placed on MeNB place, and MeNB and SeNB respectively have corresponding RLC/MAC.MeNB need to pass through L2 measuring amount, understands the performance of using after dual link.

Step 1:MeNB triggers SeNB by X2 interface and carries out L2 measurement, in the middle of comprise and need to collect L2 measuring amount, be i.e. DL packet delay, QCI=i.

Optionally, carry time started t1, allow SeNB constantly start to collect at t1 the DL packet delay result that QCI is the split carrying of i.

Optionally, MeNB configuration SeNB reports original DL packet delay to collect result.

Step 2:SeNB triggers according to MeNB, and for Split, relevant L2 measurement is carried out in carrying.Meanwhile, MeNB carries and also carries out DL packet delay measurement Split, and now MeNB, when statistics PDCP SDU bag, need to send to the PDCP SDU bag eliminating of SeNB.

Under split carrying, PDCP layer, at MeNB, when SeNB carries out DL packet delay measurement, can move down the arrival reference point PDCP upper SAP of packet in measuring process, with RLC upper SAP, replaces.

If in step 1, MeNB configuration SeNB reports original DL packet delay to collect result, and SeNB collects data report to MeNB by original DL packet delay;

Step 4:MeNB is according to the L2 measurement result of the SeNB side of receiving, and the L2 measurement result of self, judges the performance of current use DC and adjusts.

Such as, the split that the split that MeNB contrast MeNB measures carries corresponding DL packet delay and SeNB measurement carries corresponding DL packet delay, adjust corresponding shunt ratio, or according to the L2 measurement result of SeNB, the performance boost situation after DC is used in judgement, and determines whether still to continue DC;

In force, MeNB also can be by the L2 measurement result of the SeNB receiving, and the L2 measurement result of self, and direct one reports OAM, for OAM Performance Detection.A kind of preferably mode is: MeNB gives the correct time in measurement result, SCG is carried to corresponding L2 measurement result and by sign, distinguished, so which L2 measurement result OAM can determine, for SCG, carries; Further, can also carry corresponding SeNB sign.

If MeNB receives raw measurement data, the original DL packet delay that MeNB also can measure the SeNB receiving collects data, the original DL packet delay measuring with MeNB collects Data Integration, utilize existing DL packet delay computing formula, draw the DL packet delay measurement result under final split carrying, report OAM, for OAM, analyze.
