Description

Method and device for processing unauthorized carrier measurement report
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing an unlicensed carrier measurement report.
Background
In cellular mobile communication systems, cell reselection and handover are important functions thereof. In order to successfully implement cell reselection, the UE needs to measure the signal quality of different cells so as to select a suitable cell for camping. After a certain cell establishes connection with the network, the UE still needs to measure the signal quality of its neighboring cells in order to select a suitable cell for handover, so as to meet the mobility requirement.
Fig. 1 is a flowchart of a measurement process in an evolved UMTS terrestrial radio access network EUTRAN system in the related art, and as shown in fig. 1, a specific process of the measurement in a connected state is as follows: an Evolved UMTS Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, abbreviated as EUTRAN, where UMTS is Universal Mobile Telecommunications System) on a Network side sends a measurement control message to a UE, where the measurement control message includes a measurement identifier, a measurement object, a report configuration, and other measured related attributes. The UE executes measurement according to the measurement object and report configuration in the measurement control message, the measurement process is that the physical layer executes actual measurement and reports the measurement result to the layer three, the layer three judges whether to trigger the measurement report according to the processed measurement result after processing, and if the measurement report is triggered, the measurement report is generated and reported to the network side.
The measurement identifier is used as an index of the whole measurement configuration and comprises two sub-identifiers, a measurement object sub-identifier and a report configuration sub-identifier, wherein each sub-identifier comprises respective related attributes, and the measurement object sub-identifier comprises measurement object attributes such as carrier frequency, a neighbor cell list and the like; the report configuration sub-identifier includes a report configuration attribute, for example, event-triggered reporting or periodic reporting, where the Trigger event is defined by a Trigger condition (Trigger conditions a1, a2, etc.), a threshold and an offset related To the Trigger condition, a Trigger Time length (Time To Trigger, TTT for short), a reporting frequency, and the like.
For an event-triggered measurement task, a measurement object is considered to satisfy an event-triggered condition when the duration for which the measurement object satisfies an admission condition for the event (e.g., neighbor signal quality is better than a threshold) is greater than or equal to TTT. When the measurement objects meet the triggering condition of the event, the measurement report is reported to the network side, and the measurement objects in the reported report are sequenced according to the measurement set by the network, and are optimally in front. Fig. 2 is a schematic diagram of a time length to trigger TTT in the related art, as shown in fig. 2, taking the example that the quality of a signal of an adjacent cell is higher than a specified threshold to trigger a reporting measurement report, a terminal receives a measurement result of a physical layer at T3, determines that an admission condition of an event is satisfied after layer three processing, starts the TTT, and ends from the TTT to T8, during which all physical layer measurement results received by the terminal satisfy the admission condition of the event after layer three processing, and then the terminal triggers the reporting of the measurement report. If the admission condition of the event is not satisfied after the layer three processing is carried out on the bottom layer measurement result received at any time in the period, the TTT is stopped and waits for the next arrival of T3 to restart.
In order to provide a higher data rate for a mobile user, a Carrier Aggregation technology (CA) is proposed in a Long Term Evolution advanced (Long Term Evolution advanced, LTE-a for short), which aims to provide a larger bandwidth for a UE with corresponding capability and improve the peak rate of the UE. In LTE, the maximum downlink transmission bandwidth supported by the system is 20MHz, and carrier aggregation is to aggregate two or more Component Carriers (CCs) to support a transmission bandwidth greater than 20MHz and not greater than 100MHz at most. After introducing the carrier aggregation technology, a UE in a connected state may communicate with a source base station through multiple Component Carriers (CCs) at the same time, and after introducing the CA technology, a Primary serving Cell (Pcell) and a Secondary serving Cell (Scell) are also introduced.
Due to the shortage of frequency spectrum resources and the rapid increase of large-flow services of mobile users, the requirement of adopting high frequency points such as 3.5GHz for hot spot coverage is increasingly obvious, and nodes with low power become a new application scene so as to increase the throughput of users and enhance the mobile performance. However, due to the fact that signal attenuation of high frequency points is relatively severe, coverage of a cell is relatively small, and the cell is not co-sited with an existing cell, at present, a new enhancement scheme is sought by a plurality of companies and operators, and Dual Connectivity is one of the enhancement schemes. A terminal under dual connectivity may stay connected to more than two network nodes at the same time, but the control plane connection has a connection to only one of the cells, e.g. a macro cell. The multiple service nodes of the terminal are multiple base stations, and the time delay between the base stations is not negligible. For example, one network node is a macro base station called MeNB, and another network node is a small cell base station called SeNB.
With the rapid growth of data traffic, licensed spectrum will not be able to withstand such huge amounts of data in the near future; LTE operators consider deploying LTE in Unlicensed spectrum resources (Unlicensed carriers), by which data traffic in licensed carriers is shared. Unlicensed carriers (unlicensed spectrum) refer to spectrum (or carriers) that can be used without authorization under the compliance with government regulations (radio regulations) by a government agency (e.g., the national radio regulatory commission). For example, microwave ovens, remote control toy planes, Wireless mice, Wireless keyboards, Wireless Fidelity (WiFi) and the like use unlicensed carriers. In some cases, the unlicensed carrier needs to be used by a contention mechanism, such as Listen Before Talk (LBT). If the base station (including the WiFi access point) does not contend for the resource, the unlicensed carrier cannot be used. The unlicensed carrier and the licensed carrier may be used in a carrier aggregation manner or in a dual connectivity manner, where the unlicensed carrier is generally used as a supplement to data transmission, that is, the licensed carrier is used as a primary serving cell and the unlicensed carrier is used as a secondary serving cell.
The unlicensed carrier resources have great particularity, in this scenario, the measurement process is still performed according to the measurement process of the LTE system, but for the triggering of the measurement report, since the pilot Resource on the unlicensed carrier needs to be used by contention in the unlicensed carrier environment, including a signal sent by the eNB for Radio Resource Management (RRM) measurement of the terminal, if the resource contention fails, the signal for measurement cannot be transmitted, the terminal cannot measure the signal strength and/or quality of the unlicensed carrier, if the triggering of the measurement report is still done according to the existing mechanisms of the LTE system, it may cause a false triggering of the measurement report, or the measurement report is not triggered, so that the base station cannot perform reasonable mobility processing judgment according to the reliable and accurate RRM measurement report, and call drop can be generated in serious cases.
In view of the above problems in the related art, no effective solution is currently available.

It should be noted that, in an optional implementation manner of this embodiment, the manner of triggering the measurement report reporting operation in step S12 may be triggered according to a manner of triggering a measurement report reporting specified by a protocol in the existing 3 GPP.
In an application scenario in this embodiment, the first method may be: the method comprises the steps that a terminal UE receives n measurement results reported to a layer 3 after being filtered by a physical layer 1 within an evaluation time window configured by a network, wherein the n measurement results are respectively R0 and R1.. Rn-1, wherein R0 is an analysis evaluation value of a first waiting layer three, and the admission condition of RRM event evaluation is met after judgment of the layer three, so that the evaluation time window is started, the time at the moment is set to be T0, R1 is an analysis evaluation value of the second received waiting layer three, the time at the moment is recorded as T1, and by analogy, the time when the measurement result of the Rn-1 is received is recorded as Tn-1. And the time difference of the analysis and evaluation values of two adjacent waiting layers III is T1-T0 and T2-T1 … … Tn-1-Tn-2 respectively.
Further, the above records were T1-T0, T2-T1. . The Tn-1-Tn-2 time difference is subjected to one of the following statistical treatments: calculate the average, i.e.: mean { (T1-T0), (T2-T1) … … (Tn-1-Tn-2) } ═ Tn-1-T0/(n-1); it is then determined whether the calculated average value exceeds or falls below some length threshold TLthresh1 configured by the eNB. If the conditions defined by the system are met, triggering a measurement report to the eNB in the form of an RRM mobile measurement event, otherwise failing to trigger the reporting of a related event or stopping the evaluation time window.
In this embodiment, when the second method is adopted, the method for determining whether to trigger the operation of reporting the measurement report containing the mobile measurement event according to the output result by the terminal involved in step S306 in this embodiment may be implemented by the following method:

step S22: if so, the terminal triggers the operation of reporting the measurement report;
step S23: if not, the terminal forbids triggering the operation of reporting the measurement report or stops evaluating the time window; or, when the determination result is negative and the network side still indicates the terminal to trigger the operation of reporting the measurement report, the terminal reports the measurement report and reports indication information for indicating that the mobile measurement event is an unreliable measurement event.
In an application scenario in this embodiment, the second method may be: the method comprises the steps that a terminal UE receives n measurement results reported to a layer 3 after being filtered by a physical layer 1 within an evaluation time window configured by a network, wherein the n measurement results are respectively R0 and R1..

The time difference of T1-T0 and T2-T1 … … Tn-1-Tn-2 recorded above is further subjected to a statistical treatment as follows: calculating a variance value, namely: VAR { (T1-T0), (T2-T1) … … (Tn-1-Tn-2) }. It is then determined whether the calculated variance value exceeds or falls below some length threshold TLthresh2 configured by the eNB. The triggered measurement report may be reported to the eNB in the form of an RRM mobile measurement event if the system defined conditions are met, otherwise the reporting of the related event cannot be triggered or the evaluation time window is stopped.
When the third method is adopted in this embodiment, the method for determining whether to trigger the operation of reporting the measurement report containing the mobile measurement event according to the output result by the terminal involved in step S306 in this embodiment may be implemented by the following method:
step S31: the terminal judges whether the low-delay sampling number is larger than a third threshold value or not;

Optionally, the evaluation time window is a time length preconfigured for the terminal by the network side, or is a time length to trigger TTT in the RRM measurement configuration.
It should be noted that, the above modules may be implemented by software or hardware, and for the latter, the following may be implemented, but not limited to: the modules are all positioned in the same processor; alternatively, the modules are respectively located in a plurality of processors.
The invention will now be illustrated with reference to an alternative embodiment thereof;
this optional embodiment provides a method for triggering an unlicensed carrier measurement report, where the implementation process of the method includes:
the method comprises the steps that a terminal UE receives n measurement results reported to a layer 3 after being filtered by a physical layer 1 within an evaluation time window configured by a network, wherein the n measurement results are respectively R0 and R1. And the time difference of the analysis and evaluation values of two adjacent waiting layers III is T1-T0 and T2-T1 … … Tn-1-Tn-2 respectively. These time differences may not be the same, since the eNB is constrained by the LBT mechanism, and the uncertainty of the transmitted measurement pilot signal results in an effective analysis evaluation value that the UE can obtain by measurement, which is uncertain and aperiodic on the time axis.
The evaluation time window may be configured to the terminal by the eNB, and if not configured, the TTT length in the current RRM measurement configuration may also be used as the length of the evaluation time window of the current measurement task.
If the allow/exit condition is not met all the time in the evaluation process of the RRM event, the UE performs one or more of the following statistical treatments on the recorded T1-T0 and T2-T1 … … Tn-1-Tn-2 time difference values at the end of the evaluation time window:
(1): calculate the average, i.e.: mean { (T1-T0), (T2-T1) … … (Tn-1-Tn-2) } ═ Tn-1-T0/(n-1); it is then determined whether the calculated average value exceeds or falls below some length threshold TLthresh1 configured by the eNB. If the conditions defined by the system are met, triggering the measurement report to the eNB in the form of RRM mobile measurement event, otherwise, not triggering the report of the relevant event.
(2): calculating a variance value, namely: VAR { (T1-T0), (T2-T1) … … (Tn-1-Tn-2) }. It is then determined whether the calculated variance value exceeds or falls below some length threshold TLthresh2 configured by the eNB. The triggered measurement report may be reported to the eNB in the form of an RRM mobile measurement event if the system defined conditions are met, otherwise the reporting of the related event cannot be triggered.
(3): counting the number of low-delay samples which are lower than or equal to a certain length threshold TLthresh3 configured by the eNB in the time difference, if the number of low-delay samples exceeds a certain number threshold Nthresh configured by the eNB, triggering a measurement report to be reported to the eNB in the form of an RRM mobile measurement event, otherwise, not triggering the report of a related event.
The above can be reported as a completely new RRM mobility measurement event independently of the existing RRM mobility measurement event.
The above contents can also be reported jointly with the existing RRM mobile measurement event, providing the eNB with supplementary beneficial reference information.
The eNB can obtain the real pattern distribution situation of the pilot signal which can be measured by the UE side through the information content reported by the UE, so that the wireless situation of the UE side on the unauthorized carrier wave can be known better.
By the optional embodiment, the problem that the base station makes unreasonable decision according to an inaccurate measurement report and a call drop occurs in a serious situation due to false triggering of the RRM measurement report or non-triggering of the measurement report in the related technology can be solved, and the service experience of a user is improved.
It should be noted that the principle of the optional embodiment may not be limited to the LTE system, but is also applicable to all communication systems that need to use the unlicensed carrier resource through contention; the invention can prevent the terminal from reporting unreliable mobile events by mistake, so that the network is more reliable and efficient in the aspect of terminal mobility/wireless resource management.
The alternative embodiment will be described in detail with reference to the drawings and specific embodiments thereof;
in this optional embodiment, the related base station takes two cells as an example, where a working frequency point of a cell 1 deployed on an authorized carrier is f1, and a working frequency point of a cell 3 deployed on an unauthorized carrier is f 3. For the cell on the licensed carrier to measure and report through RRM, in the specific embodiment of the present embodiment, only RRM measurement evaluation for the cell 3 is performed.
Example one
As shown in fig. 1, the network side sends an RRC message containing measurement control information to the UE, where the RRC message includes a measurement task: and searching and measuring that the quality of the signal of a certain adjacent area is better than a certain threshold, thereby triggering an event (A4), indicating that the related trigger threshold is Thresh-1 and the measured object is an unauthorized carrier frequency point f 3. In addition, the base station also informs the terminal in the measurement control information, and if the average value of the time difference of the effective measurement result is lower than or equal to 50ms, the measurement report containing A4 can be triggered; the base station informs the terminal in the measurement control information that the length of the evaluation time window for the unlicensed carrier is, for example, 210 ms. After receiving the measurement task and configuration, the UE performs RRM measurements and related evaluations on the measurement object f 3.
Fig. 10 is a schematic diagram of a method for triggering an unlicensed carrier measurement report according to an alternative embodiment of the present invention, as shown in fig. 10, at T2, the terminal measures the signal quality of cell 3, which is lower than Thresh-1 after layer three processing, does not satisfy the trigger condition of a4, and does not perform RRM event evaluation admission processing.
At T3, the terminal measures that the signal quality of cell 3 is higher than Thresh-1 after layer three processing, which is the first effective measurement result meeting the event triggering condition, and then enters the RRM-related event evaluation admission processing. Since cell 3 is deployed on an unlicensed carrier, an evaluation time window is initiated and the time T3 is recorded.
At T4, the terminal measures the signal quality of cell 3 again, which is higher than Thresh-1 after layer three processing, and records time T4, and continues the RRM event evaluation, with a time difference of 80ms between T4 and T3.
If the signal quality of the cell 3 at this time is lower than Thresh-1 after the layer three processing, the RRM-related event evaluation admission/exit processing is entered, and then the evaluation time window is immediately stopped, so that the measurement report is not triggered, and this alternative embodiment is ended. It should be noted that the following embodiments of this alternative embodiment are also similar.
At T5, the terminal measures the signal quality of cell 3, which is still higher than Thresh-1 after layer three processing, records time T5, continues RRM event evaluation, and the time difference between T5 and T4 is 40 ms.
At T6, the terminal measures the signal quality of cell 3, which is still higher than Thresh-1 after layer three processing, records time T6, continues RRM event evaluation, and the time difference between T6 and T5 is 40 ms.
At T7, the terminal measures the signal quality of cell 3, which is still higher than Thresh-1 after layer three processing, records time T7, continues RRM event evaluation, and the time difference between T7 and T6 is 40 ms.
Later on, the evaluation time window ends at (T3+210ms), all received valid measurement signal qualities of cell 3, after layer three processing, are all higher than Thresh-1, a total of 5 valid measurement results are received, there are 4 time differences, 80ms, 40ms, 40ms, 40ms, with an average value of 50ms, equal to the specified comparison threshold of 50ms, the time window is evaluated, so that a measurement report such as an a4 event can be triggered, and the average value of 50ms of the time differences is also reported to the base station. Otherwise, if the average value of the time difference is above the comparison threshold for 50ms, a measurement report such as an a4 event may not be triggered.
Example two
As shown in fig. 1, the network side sends an RRC message containing measurement control information to the UE, where the RRC message includes a measurement task: and searching and measuring that the quality of the signal of a certain adjacent area is better than a certain threshold, thereby triggering an event (A4), indicating that the related trigger threshold is Thresh-1 and the measured object is an unauthorized carrier frequency point f 3. In addition, the base station also informs the terminal in the measurement control information, and if the average value of the time difference of the effective measurement result is lower than or equal to 50ms, the measurement report containing A4 can be triggered; the base station informs the terminal in the measurement control information that the evaluation time window length for the unlicensed carrier is the same as the TTT, for example, 380 ms. After receiving the measurement task and configuration, the UE performs RRM measurements and related evaluations on the measurement object f 3.
Fig. 11 is a schematic diagram of a method for triggering an unlicensed carrier measurement report according to an alternative second embodiment of the present invention, as shown in fig. 11, at T2, the terminal measures the signal quality of cell 3, which is lower than Thresh-1 after layer three processing, does not satisfy the trigger condition of a4, and does not perform RRM-related event evaluation admission processing.
At T3, the terminal measures that the signal quality of cell 3 is higher than Thresh-1 after layer three processing, which is the first effective measurement result meeting the event triggering condition, and then enters the RRM-related event evaluation admission processing. Since cell 3 is deployed on an unlicensed carrier, the evaluation time window is initiated, but the base station is not configured, so TTT is used instead of 380ms by default, at which point the evaluation time window is initiated and the time T3 is recorded.
At T4, the terminal measures the signal quality of cell 3 again, which is higher than Thresh-1 after layer three processing, and records time T4, and continues the RRM event evaluation, where the time difference between T4 and T3 is 170 ms.
If the signal quality of the cell 3 at this time is lower than Thresh-1 after the layer three processing, the evaluation time window enters RRM-related event evaluation admission/exit processing, and then the evaluation time window is immediately stopped, so that the measurement report is not triggered, and this embodiment ends.
At T5, the terminal measures the signal quality of cell 3, which is still higher than Thresh-1 after layer three processing, and records time T5, and continues the RRM event evaluation, where the time difference between T5 and T4 is 190 ms.
Later the evaluation time window ends at (T3+380ms), the evaluation time window, the signal quality of all received cells 3, after layer three processing, is higher than Thresh-1, there are 2 time differences, 170ms and 190ms respectively, the average value is 180ms, which is greater than the specified comparison threshold 50ms, after receiving 3 valid measurement results, so that cell 3 does not satisfy the event evaluation time window trigger condition, and the UE may not trigger the measurement report such as the a4 event.
It should be noted that, in the present embodiment, if the conventional RRM processing mechanism is adopted, the measurement report such as the a4 event may be triggered, but according to the present invention, a layer of evaluation mechanism is added and the condition defined by the system is not met, so the measurement report such as the a4 event cannot be triggered.
EXAMPLE III
As shown in fig. 1, the network side sends an RRC message containing measurement control information to the UE, where the RRC message includes a measurement task: searching and measuring the quality of a signal of a certain adjacent area to be better than a certain threshold, thereby triggering an event (A8, defined as a new mobile measurement event), indicating that the related triggering threshold is Thresh-1, and the measurement object is an unauthorized carrier frequency point f 3. In addition, the base station also informs the terminal in the measurement control information, and if the variance value of the time difference of the effective measurement result is less than or equal to 300ms, the measurement report containing A8 can be triggered; the base station informs the terminal in the measurement control information that the length of the evaluation time window for the unlicensed carrier is 260 ms. After receiving the measurement task and configuration, the UE performs RRM measurements and related evaluations on the measurement object f 3.
Fig. 12 is a schematic diagram of a method for triggering an unlicensed carrier measurement report according to a third alternative embodiment of the present invention, as shown in fig. 12, at T2, the terminal measures the signal quality of cell 3, which is lower than Thresh-1 after layer three processing, does not satisfy the trigger condition of a8, and does not perform RRM-related event evaluation admission processing.
At T3, the terminal measures that the signal quality of cell 3 is higher than Thresh-1 after layer three processing, which is the first effective measurement result meeting the event triggering condition, and then enters the RRM-related event evaluation admission processing. Since it is the measurement evaluation task for the A8 event, an evaluation time window is initiated and the time T3 is recorded.
At T4, the terminal measures the signal quality of cell 3 again, which is still higher than Thresh-1 after layer three processing, records time T4, continues RRM event evaluation, and the time difference between T4 and T3 is 30 ms.
If the signal quality of the cell 3 at this time is lower than Thresh-1 after the layer three processing, the RRM-related event evaluation admission/exit processing is entered, and then the evaluation time window is immediately stopped, so that the measurement report is not triggered, and this embodiment ends. The principle of the following process is similar and not repeated!
At T5, the terminal measures the signal quality of cell 3, which is higher than Thresh-1 after layer three processing, records time T5, continues RRM event evaluation, and the time difference between T5 and T4 is 50 ms.
At T6, the terminal measures the signal quality of cell 3, which is higher than Thresh-1 after layer three processing, records time T6, continues RRM event evaluation, and the time difference between T6 and T5 is 55 ms.
At T7, the terminal measures the signal quality of cell 3, which is higher than Thresh-1 after layer three processing, records time T7, continues RRM event evaluation, and the time difference between T7 and T6 is 35 ms.
At T8, the terminal measures the signal quality of cell 3, which is still higher than Thresh-1 after layer three processing, records time T8, continues RRM event evaluation, and the time difference between T8 and T7 is 70 ms.
Later, the evaluation time window ends at (T3+260ms), all the received effective signal qualities of the cell 3 are higher than Thresh-1 after the layer three processing, 6 effective measurement results are received altogether, 5 time differences are respectively 30ms, 50ms, 55ms, 35ms and 70ms, the variance value is 257.5ms and is less than the specified threshold 300ms, the cell 3 satisfies the event admission condition and continues to evaluate the time window time, so that a measurement report such as an a8 event can be triggered, and the variance value 257.5ms of the time differences can be reported to the base station. Otherwise, if the variance value of the time difference is higher than the comparison threshold for 300ms, a measurement report such as an A8 event may not be triggered.
Example four
As shown in fig. 1, the network side sends an RRC message containing measurement control information to the UE, where the RRC message includes a measurement task: searching for and measuring that the quality of a signal of a certain neighbor cell is better than that of the current main serving cell by a certain Offset threshold Offset, thereby triggering an a3 event, where for convenience of description, the Offset is set to 0, and the measurement object is an unlicensed carrier frequency point f 3. In addition, the base station also informs the terminal in the measurement control information, and if the time difference of the effective measurement result is less than or equal to 55ms, and the number of low-delay samples is greater than the number threshold 3, a measurement report containing an A3 event can be triggered; the base station informs the terminal in the measurement control information that the length of the evaluation time window for the unlicensed carrier is equal to TTT250ms by default. After receiving the measurement task and configuration, the UE performs RRM measurements and related evaluations on the measurement object f 3.
Fig. 13 is a schematic diagram of an alternative embodiment of the present invention, as shown in fig. 13, at T2, the terminal measures the signal quality of cell 3, which is lower than the signal quality of the current primary serving cell after the layer three processing, does not satisfy the trigger condition of A3, and does not perform the RRM-related event evaluation admission processing.
At T3, the terminal measures the signal quality of cell 3, which is higher than the signal quality of the current primary serving cell after layer three processing, and is the first valid measurement result satisfying the event triggering condition, and then enters the admission process of RRM-related event evaluation. Since cell 3 is deployed on an unlicensed carrier, an evaluation time window is initiated and the time T3 is recorded.
At T4, the terminal measures the signal quality of cell 3, which is still higher than the signal quality of the current primary serving cell after layer three processing, records time T4, continues RRM event evaluation, and the time difference between T4 and T3 is 36 ms.
At T5, the terminal measures the signal quality of cell 3, which is higher than the signal quality of the current primary serving cell after layer three processing, records time T5, continues RRM event evaluation, and the time difference between T5 and T4 is 38 ms.

Otherwise, if the total number of low-delay samples with the time difference value lower than or equal to the comparison threshold 55ms is less than or equal to the number threshold 3, a measurement report such as an a3 event may not be triggered.
