Description

The present invention relates to the field of communications technologies, and in particular, to a measurement report processing method and system in a Universal Mobile Telecommunications System (UMTS), and wireless network control. RNC (Radio Network Controller) User equipment. BACKGROUND OF THE INVENTION In a universal mobile communication system, service continuity of a mobile subscriber is ensured by handover of a mobile station serving cell. FIG. 1 is a schematic diagram of a process of measuring a measurement report in the prior art. As shown in FIG. 1 , the process of the handover includes: Step S101: A user equipment (UE, User Equipment) reports a measurement report of an event type to the RNC. The measurement report mainly includes two parts: measurement results and event results. The radio signal quality of the cell measured by the UE is recorded in the measurement result, and some event conditions are recorded in the event result. In step S102, after receiving the measurement report, the radio network controller determines the type of the handover according to its own algorithm. And the target serving cell; Step S103, the RNC then sends a command message to the UE to inform the UE of the action that needs to be performed. Step S104: After receiving the message, the UE performs the action required in the message. In step S105, the UE sends an action completion message to the RNC. In step S102, when the RNC receives the measurement report, if the UE is performing an action, such as radio bearer setup or handover, the RNC needs to buffer the received measurement report. During the UE's execution of the action, the RNC may continuously receive multiple measurement reports and cache them. After the execution of the UE action is completed, the RNC performs decision processing according to its own algorithm for each cached measurement report. It can be seen from the above that the time after the execution of the UE action is completed is longer than the time when the UE reports the measurement report. During this time, the UE may have moved, and the wireless environment in which it is located may also change. Therefore, the wireless measurement result and the event result in the previously buffered measurement report may have occurred at the time after the UE action is completed. Change, no longer meet the requirements. If the RNC still makes a decision based on the buffered measurement report after the UE action is completed, the decision made by the RNC may be wrong, which may cause the UE to switch to a cell of poor quality and cause dropped calls. 2 is a schematic diagram of a call loss measurement report caused by an RNC error processing cache measurement report in the prior art. As shown in FIG. 2, in a process of performing rate adjustment by a UE, a cell Celll (ie, cell 1) signal quality changes due to UE mobility. Poor, the UE first reports a measurement report, and the cell Celll satisfies the 1B event condition. Then, the UE moves back, the cell Cel1 signal quality is improved, the UE reports a measurement report, and the cell Celll satisfies the reported 1D condition. Thus, during the rate adjustment process, the RNC buffers 2 measurement reports. After the rate adjustment is completed, the RNC processes the 1B event report first, and sends an active set update message to the UE, requesting to delete the radio link where the cell Cellel is located, although the quality of the cell Celll is already the best for the UE. After deleting the wireless link where the cell Cellel is located, the UE is likely to drop the call. The meanings of common measurement events are shown in Table 1 below:

Table 1 Therefore, the existing measurement report processing method is easy to cause the RNC to make wrong decisions and affect the user experience.

In order to make the technical solutions of the present invention clearer and clearer, the following will be further described in detail with reference to the accompanying drawings. The solution of the embodiment of the present invention is: When the RNC processes the measurement report reported by the UE after the UE performs the predetermined action, it first checks whether the cached measurement report is valid, and if the measurement report is still valid, the RNC continues to process. The measurement report; if the measurement report has expired, the RNC discards the measurement report, so that the RNC makes a correct decision, avoiding the user dropping the call, and improving the user experience. FIG. 3 is a schematic flowchart of a method for processing a measurement report according to an embodiment of the present invention. As shown in FIG. 3, this embodiment provides a method for processing a measurement report, including: Step S301: The RNC receives a measurement report reported by the UE; S302. When the UE has a predetermined action being executed, the RNC records the measurement result of each cell in the measurement report, and buffers the measurement report. Step S303, after the UE completes the performing the predetermined action, the RNC determines the validity of each measurement report according to the latest measurement result of the cell, and performs corresponding processing on each measurement report according to the determination result.

During the mobile process, the UE continuously detects the signal quality of the current serving cell and the neighboring cell. If the signal quality of the current serving cell or the neighboring cell changes, the UE reports the measurement report to the RNC, and the RNC needs to process the measurement report. The handover of the mobile station serving cell ensures the continuity of service of the mobile subscriber. At the same time, on the RNC side, according to the current system operating environment, the UE is instructed to perform corresponding predetermined actions, such as establishing a radio bearer, adjusting an uplink rate, or changing a serving cell. Taking the uplink rate as an example, the RNC needs to send a transport channel reconfiguration message to the UE to enable the UE to perform a rate adjustment action. After the UE completes the rate adjustment action, the UE returns a transport channel reconfiguration complete message to the RNC. The RNC continuously receives the measurement report reported by the UE, and the RNC may continuously receive multiple measurement reports during the UE performing the predetermined action. In this embodiment, if the RNC receives the measurement report reported by the UE in the process of performing the predetermined action, the RNC records the measurement result of each cell in each measurement report, and buffers the measurement report. When the current measurement report is cached, the RNC checks whether the cell ID and the measurement result of the current measurement report have the same cell identifier in the measurement result of the old measurement report that has been buffered. If there is a cell identifier, the measurement result of the cell in the current measurement report is used to cover the measurement result of the cell in the old measurement report. The measurement report includes the measurement result and the event result, and the measurement result includes the radio signal quality of the cell measured by the UE; the event result includes which cells satisfy which event conditions. Since the RNC will use the cell measurement result in the current measurement report to cover the measurement result of the same cell in the previous measurement report when the measurement report is cached, after the UE performs the predetermined action, each cell in the measurement report of the RNC buffer is used. The measurement results are the latest measurement results. That is to say, when receiving this measurement report, multiple measurement reports may be buffered in the front, and multiple measurement reports buffered in the previous state need to be checked one by one. After the UE performs the scheduled action, the RNC re-determines whether the cell in the event result in each measurement report continues to satisfy the event condition according to the latest measurement result of each cell. If the buffer measurement report is valid, the RNC can perform subsequent processing on the measurement report. If not, the cached measurement report has expired and needs to be discarded. Thereby, the RNC sends an erroneous command message to the UE caused by the processing of the failed measurement report, which affects the user's feelings or causes a dropped call. As shown in FIG. 4, in step S303, the RNC determines the validity of each measurement report according to the latest measurement result of the cell, and performs corresponding processing on each measurement report according to the determination result. Step S401: The RNC reports the sequence according to the measurement report. Sequence, and calculating, according to the latest measurement result of the cell, the event condition according to the event result in the measurement report; in step S402, the RNC determines, according to the calculation result, whether the cell in the event result in the measurement report satisfies the event condition, and if so, enters Step S403; otherwise, proceeding to step S404; Step S403, the measurement report is valid, and the measurement report is subsequently processed; Step S404, the measurement report is invalid, and the measurement report is discarded. The above measurement reports include: an intra-frequency buffer measurement report, an inter-frequency buffer measurement report, and/or an inter-system cache measurement report. The following is a detailed description of the solution of the intra-frequency buffer measurement report, the inter-frequency buffer measurement report, and the inter-system cache measurement report. Embodiment 1: FIG. 5 is a measurement report processing method according to an embodiment of the present invention. For example, as shown in FIG. 5, in this example, the downlink bearer is assumed to be carried on the transport channel HS-DSCH (High Speed Downlink Shared Channel). On the transport channel DCH (Dedicated Channel). In the active set, there are cells Celll and Cell2, where Cell2 is a serving cell. The processing procedure is as follows: Step S501: The RNC sends a transport channel reconfiguration message to the UE, because the uplink rate is required to be adjusted. Step S502: The UE1 reports the measurement report (Celll satisfies the 1B event condition) due to the UE's movement. S503, because the UE is in the process of speed regulation, the RNC records the signal quality measurement result of Celll and Cell2 in the measurement report, and buffers the measurement report; Step S504, because the UE moves, the Celll quality becomes better, and the UE reports Measurement report (Celll meets 1D event conditions); Step S505, because the UE is in the process of speed regulation, the RNC records the signal quality measurement result of Celll and Cell2 in the measurement report, and buffers the measurement report; Step S506, the UE speed adjustment is completed, and the transmission channel is replied to the RNC. The completion message is sent; in step S507, the RNC processes the cached 1B measurement report in the order in which the measurement report is reported. The current signal quality of Celll and Cell2 is taken into the IB event. It is found that Cell no longer satisfies the 1B event. It is considered that the 1B measurement report has expired, so the 1B report is discarded.

The calculation formula for the 1B event is:

10 · LogM _ou + CI0 _ou LogM _Besl ― (R _u + H _lb 12)

In the above formula (1):

The MCM is a measurement result of an active set cell that performs an event IB decision;

CI0 _old is the cell individual offset of the active set cell that performs the event 1B decision; is the measurement result of the active set cell; N _A is the number of cells in the current active set;

M _BEST is the measurement result of the strongest cell in the active set;

W is a parameter specified by the RNC, indicating the weight of the best cell in the calculation;

R is the scope of the report;

H _lb is the hysteresis parameter for event 1B. Step S508, the RNC processes the cached 1D measurement report. The current signal quality of Celll and Cell2 is taken into the 1D event formula, and it is found that Cell still satisfies the 1D event. It is considered that the 1D measurement report is valid and continues to be processed. Need to change the serving cell to Celll. Among them, the calculation formula of the 1D event is:

10 · LogM _NotBest ≥ 10 · LogM _Best + H _ld /2 (2) In the above formula (2):

M _NotBes t is a measurement result of the active set cell;

M _Best is the measurement result of the strongest cell in the active set; H _ld is the hysteresis parameter of event 1D. Step S509, the RNC sends a physical channel reconfiguration message to the UE, and changes the serving cell to Celll. Embodiment 2 FIG. 6 is a flowchart of a process of inter-frequency buffer measurement report in an embodiment of a measurement report processing method according to an embodiment of the present invention. As shown in FIG. 6, in this example, a service download is assumed to be carried on a transport channel HS-DSCH ( On the High Speed Downlink Shared Channel), the uplink is carried on the transport channel DCH (Dedicated Channel). The working carrier frequency is Fl, and there is a cell Celll in the active set. The current working carrier frequency is not good. The non-working different carrier frequency is F2, and the frequency of the cell Cell2 is F2. The process is as follows: Step S601: The RNC sends a transport channel reconfiguration message to the UE according to the need to adjust the uplink rate. Step S602: The UE performs a measurement report because the UE moves, and the UE reports the measurement report (the different carrier frequency satisfies the 2C event). Condition); Step S603, because the UE is in the process of speed regulation, the RNC records the signal quality measurement result of the different carrier frequency cell Cell2 in the measurement report, and buffers the measurement report; Step S604, because the UE moves, different The quality of the carrier frequency is deteriorated, and the UE reports the measurement report (the different carrier frequency satisfies the 2E event condition); Step S605, because the UE is in the process of speed regulation, the RNC records the signal quality measurement of the different carrier frequency cell Cell2 in the measurement report. As a result, the measurement report is cached. In step S606, the UE speed adjustment is completed, and the transport channel reconfiguration complete message is returned to the RNC. In step S607, the RNC processes the buffered 2C measurement report according to the sequence reported in the measurement report. The current Cell2 signal quality is taken into the carrier frequency quality estimation formula to calculate the quality of the different carrier frequency F2. The carrier frequency quality estimation formula is as follows:

Q 10 - LogM W _i - LogM ₁ (3)

If the carrier frequency j is the carrier frequency being used, then the virtual activation set described below refers to the active set in which the carrier frequency is being used. In the above formula (3), Q _frequen . _Yj is the evaluation quality (dB value) of the virtual activation set of carrier frequency j;

Mfequencyj is the evaluation quality (mW value) of the virtual activation set of the carrier frequency j; is the measurement result of the cell i in the virtual activation set of the carrier frequency j; N _Aj is the number of cells in the virtual activation set of the carrier frequency j;

M _Bestj is the measurement result of the cell with the best measurement result in the virtual activation set of the carrier frequency j; it is a parameter specified by the RC, which is used to reflect the influence degree of the measurement result of the best cell on the measurement quality evaluation. The evaluation quality calculated by the above formula (3), that is, the different carrier frequency quality, is brought into the 2C event formula. It is found that the different carrier frequency F2 no longer satisfies the 2C event, and the 2C measurement report is considered to have failed, so the 2C report is discarded. Among them, the formula for calculating the 2C event is: (4) In the above formula (4):

QNon used is the signal quality of the unused carrier frequency whose signal quality is better than the absolute threshold; T _{Non used 2c} is the absolute threshold applied to the unused carrier frequency in the inter-frequency measurement;

H _2c is the hysteresis parameter of the 2C event. In step S608, the RNC processes the buffered 2E measurement report. The signal quality of Cell2 is taken into the carrier frequency quality estimation formula (3), and the mass of the different carrier frequency F2 is calculated. The calculated different carrier frequency quality is taken into the 2E event formula, and it is found that the different carrier frequency still satisfies the 2E event. It is considered that the 2E measurement report is valid and continues to be processed. Because the working carrier frequency and the different carrier frequency quality are not good, it is necessary to turn on the intersystem measurement. Among them, the calculation formula of 2E event is as follows:

In the above formula (5):

Q _N . _{n used} is the evaluation quality of the unused carrier frequency whose signal quality is worse than the absolute threshold; T _N . _{n used 2e} is the absolute threshold _used in the decision formula;

H _2e is the hysteresis parameter of the 2E event. Step S609, the RNC sends a measurement control message to the UE, and starts inter-system measurement. Embodiment 3 FIG. 7 is a flowchart of processing an inter-system cache measurement report in an embodiment of a measurement report processing method according to an embodiment of the present invention. As shown in FIG. 7, in this example, a service download is assumed to be carried on a transport channel HS-DSCH. On the High Speed Downlink Shared Channel, the uplink is carried on the transport channel DCH (Dedicated Channel). The working carrier frequency is Fl, and there is a cell Celll in the active set. The current working carrier frequency is not good. Cell2 is a GSM cell. The process is as follows: Step S701: The RNC sends a transport channel reconfiguration message to the UE according to the uplink rate. Step S702, the quality of the cell 2 is improved due to the UE's movement, and the UE reports the measurement report (Cell2 satisfies the 3A event condition). S703, because the UE is in the process of speed regulation, the RNC records the signal quality measurement result of the different system cell Cell2 in the measurement report, and buffers the measurement report; Step S704, because the UE moves, the working carrier frequency quality becomes better. The UE reports the measurement report (the working carrier frequency satisfies the 2F event condition); Step S705, because the UE is in the process of speed regulation, the RNC records the signal quality measurement result of the working carrier cell Celll in the measurement report, and caches the The measurement report is performed; in step S706, the UE speed adjustment is completed, and the transport channel reconfiguration complete message is returned to the RNC; in step S707, the RNC processes the buffered 3A measurement report according to the sequence reported in the measurement report. The current Celll signal quality is brought into the UTRAN (UMTS Terrestrial Radio Access Network) system quality estimation formula to calculate the quality of the UTRAN system. Among them, the system quality estimation formula is:

QUWAN = 10 · LogM _N = W - \Q - Log\ £M, + (1 - ^) · 10 · LogM (6) In the above formula (6): Q _UTRAN is the active set of the UTRAN carrier currently in use. Signal quality (dB value); The signal quality (mW value) of the active set of the UTRAN carrier currently being used by MUTRAN;

M ₁ is the measurement result of the active centralized cell i;

N _A is the number of active centralized cells;

M _Bί ; _st is the measurement result of the best cell in the active set; W is a parameter specified by the RNC to reflect the degree of influence of the measurement result of the best cell on the measurement quality assessment. The calculated UTRAN system quality is brought into the 3 A event formula, and it is found that the UTRAN system no longer satisfies the 3A event, and the 3A measurement report is considered to have expired, so the 3A report is discarded. Among them, the calculation formula of the 3A event is as follows: Qj _sed ≤T _Used -H _3a l2 AND M _0ther + ( 10^ ≥ T _0ther jur +H^ 12 (7) In the above formula (7):

Q _used is the evaluation quality of the carrier frequency of the UTRAN system being used; T _Used is the absolute threshold of the triggered 3 A event configured for the working carrier frequency; Mot _{to RAT} is the measurement result of other system cells; Tot _{to RAT} is applied to other systems The absolute threshold that triggers the 3A event;

The CIOoto RAT is the cell individual offset of other system cells; H _3a is the hysteresis parameter of the 3A event. Step S708, the RNC processes the buffered 2F measurement report. The quality of the working carrier frequency F1 is calculated by taking the signal quality of Celll into the carrier frequency quality estimation formula (3). The calculated working frequency quality is taken into the 2F event formula, and it is found that the working carrier frequency still satisfies the 2F event, and the 2F measurement report is considered valid and continues to be processed. Since the quality of the working carrier frequency is good, it is necessary to turn off the intersystem measurement. Among them, the 2F event calculation formula is as follows:

QT _Used H ^ I 2 In the above formula (8): Q _Used is the evaluation quality of the carrier frequency signal being used;

T _{Used 2f} is the absolute threshold for the 2F event triggered by the carrier frequency signal being used;

H _2f is the hysteresis parameter of the 2F event. Step S709, the RNC sends a measurement control message to the UE, and the inter-system measurement is turned off. In this embodiment, the RNC performs corresponding processing on the measurement report by checking whether the cached measurement report is valid. The RNC can continue to process the measurement report only if the measurement report is still valid. The sending of an erroneous command message to the UE caused by the processing of the failed measurement report is avoided, which affects the user's feelings or causes a dropped call. FIG. 8 is a schematic structural diagram of an RNC for processing a measurement report according to an embodiment of the present invention. As shown in FIG. 8, the embodiment provides an RNC 800 for processing a measurement report, including: a receiving module 801, and a recording cache module 802. And a determination processing module 803, wherein: the receiving module 801 is configured to receive the measurement report reported by the UE; the record buffering module 802 is coupled to the receiving module 801, and is configured to record each cell in the measurement report when the UE has a predetermined action being executed. The measurement result is cached, and the measurement processing module 803 is coupled to the record buffering module 802, and configured to determine the validity of each measurement report according to the latest measurement result of the cell after the UE completes the predetermined action, and according to the judgment As a result, each measurement report is processed accordingly.

During the mobile process, the UE continuously detects the signal quality of the current serving cell and the neighboring cell. If the signal quality of the current serving cell or the neighboring cell changes, the UE reports the measurement report to the RNC 800, and the RNC 800 needs to process the measurement report. The service continuity of the mobile subscriber is ensured by the handover of the mobile station serving cell. At the same time, on the RNC 800 side, according to the current system operating environment, the UE is instructed to perform corresponding predetermined actions, such as establishing a radio bearer, adjusting an uplink rate, or changing a serving cell. For example, the RNC 800 needs to send a transport channel reconfiguration message to the UE to perform a rate adjustment action. After the UE completes the rate adjustment action, the UE returns a transport channel reconfiguration complete message to the RNC 800.

The RNC 800 continuously receives the measurement report reported by the UE through the receiving module 801. During the execution of the predetermined action by the UE, the RNC 800 may continuously receive multiple measurement reports. In this embodiment, if the receiving module 801 of the RNC 800 receives the measurement report reported by the UE in the process of performing the predetermined action by the UE, the measurement result of each cell in each measurement report is recorded by the record buffering module 802, and the measurement is performed. The report is cached. When the current measurement report is cached, the RNC 800 checks whether the cell ID and the measurement result of the current measurement report are the same in the measurement result of the old measurement report that has been buffered. If there is a cell identifier, the measurement result of the cell in the current measurement report is used to cover the measurement result of the cell in the old measurement report. The measurement report includes the measurement result and the event result, and the measurement result includes the radio signal quality of the cell measured by the UE; the event result includes which cells satisfy which event conditions. Since the RNC 800 uses the cell measurement result in the current measurement report to cover the measurement result of the same cell in the previous measurement report when the measurement report is cached, when the UE performs the predetermined action, each measurement report buffered by the RNC 800 is used. The measurement results of the cell are the latest measurement results. After the execution of the predetermined action of the UE is completed, the judgment processing module 803 of the RNC 800 re-determines whether the cell in the event result in each measurement report continues to satisfy the event condition according to the latest measurement result of each cell. If the buffer measurement report is valid, the RNC 800 can perform subsequent processing on the measurement report. If not, the cached measurement report has expired and needs to be discarded. Thereby, the RNC sends an erroneous command message to the UE caused by the processing of the failed measurement report, which affects the user's feelings or causes a dropped call. FIG. 9 is a schematic diagram of a structure of a determination processing module in an RNC that processes a measurement report according to an embodiment of the present invention. As shown in FIG. 9, the determination processing module 803 includes: a calculation unit 8031 and a determination operation unit 8032, wherein: the calculation unit 8031 And setting, according to the sequence of reporting the report report, and calculating the event condition according to the event result in the measurement report according to the latest measurement result of the cell; determining the operation unit 8032, coupled to the calculation unit 8031, and setting the calculation result according to the calculation result Determine whether the cell in the event result in the measurement report meets the event condition. If yes, the measurement report is valid, and the measurement report is subsequently processed; otherwise, the measurement report is invalid, and the measurement report is discarded. The above measurement report may be an intra-frequency buffer measurement report, an inter-frequency buffer measurement report, or an inter-system cache measurement report. If the measurement report is an intra-frequency buffer measurement report, the execution result of the determining operation unit 8032 may be that a physical channel reconfiguration message is sent to the UE to perform a serving cell handover; if the measurement report is a inter-frequency buffer measurement report, the judgment operation is performed. The execution result of the unit 8032 may be to send a control message for opening the inter-system measurement to the UE; if the measurement report is an inter-system cache measurement report, the execution result of the determining operation unit 8032 may be a control message for transmitting the inter-system measurement to the UE. According to the actual scenario, the subsequent processing process when the measurement report is valid will be different. 10 is a schematic structural diagram of a UE according to an embodiment of the present invention. As shown in FIG. 10, the UE 1000 includes: an execution module 1001, configured to perform a predetermined action; a reporting module 1002, coupled to the execution module 1001, configured to be to the RNC Evaluating the measurement report, so that when the execution module has a predetermined action being executed, the RNC records the measurement result of each cell in the measurement report; and after the execution module completes the execution of the predetermined action, the RNC determines each measurement report according to the latest measurement result of the cell. The validity of each measurement report is processed according to the judgment result. FIG. 11 is a schematic structural diagram of an embodiment of a measurement report processing system according to an embodiment of the present invention. As shown in FIG. 11, an embodiment of the present invention further provides a measurement report processing system, including: the foregoing RNC 800 and the UE 1000. In the embodiment of the present invention, the measurement report processing method, the RNC, and the system, when processing the measurement report, the RNC first checks whether the cached measurement report is valid. If the measurement report is still valid, the RNC continues to process the measurement report; if the measurement report has expired, The RNC discards the measurement report, so that the wireless measurement result and the event result in the measurement report buffered in the prior art may have changed after the UE action is completed, causing the RNC to make an erroneous decision and send the wrong command to the UE. The message, causing the user to drop the call, improves the decision-making ability and user experience of the RNC. The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and equivalent structural or process changes made by the present specification and drawings may be directly or indirectly applied to other related technical fields. The same is included in the scope of patent protection of the present invention.
