    Field of Invention
    [001] The present invention relates to the field of communication and particularly to a method, a device and a system for reporting additional measurement results. Background of the Invention
    [002] In the mobile communication system, in order to ensure the quality of service and provide a better service experience to the user, after the user equipment (abbreviated as UE) establishes a network connection in a certain cell, that UE you still need to measure the signal quality of the server cell and adjacent cells and select a suitable cell for automatic switching to meet mobility requirements.
    [003] Figure 1 is a schematic diagram of X2 interface automatic switching process according to the relevant technique, and as shown in figure 1, in the long-term evolution system (abbreviated as LTE), the automatic switching process X2 interface includes the following steps:
    [004] Step 101: a source base station sends measurement control to the UE under connected state;
    [005] Step 102: UE performs measurement and reports a measurement report;
    [006] Step 103: the source base station performs automatic switching in combination with practical situations according to the received measurement report and selects a target cell;
    [007] Step 104: Source base station sends automatic change request message to target base station which target cell belongs to, with capacity information, application server layer configuration information (abbreviated AS) , the radio resource management configuration information (abbreviated as RRM) and UE context information that is transmitted therein;
    [008] Step 105: After having performed the processing of such a resource reservation and so on, the target base station responds to the auto-change request response message to the source base station, with the auto-change command information for the UE that is transmitted therein and the autochange command information includes the target cell information (this target cell may be different from the target cell in the autochange request message);
    [009] Step 106: the source base station sends an autochange command (i.e. radio resource control reconfiguration (abbreviated as RRC)) to the UE; and
    [0010] Step 107: UE sends an auto-switch complete command to the target base station after the target cell performs random access and completes it.
    [0011] The process of automatic switching of the S1 interface is similar to that of the X2 interface above and the difference between them lies only in the fact that the interaction message during the automatic switching is forwarded through the MME.
    [0012] The main base of the above source base station which performs the automatic switch decision is the measurement results. In the LTE system, under the connected state, the particular measurement process is as follows: The network side sends a measurement control message to the UE, where the measurement control message includes the measurement ID (abbreviated as MID) , measurement object (abbreviated MO), report configuration (abbreviated RC), and other measurement-relevant attributes, where the measurement ID associates the measurement object and the report configuration together to form a complete measurement task. The measurement object includes the attributes (such as carrier frequency, list of adjacent cells, etc.) of the measurement object, with each carrier frequency only configuring a measurement object, and the report configuration includes the attributes (such as trigger of event or period report, definition of triggered event (A1, A2, ...), number of reports, etc.) of the report configuration. The UE performs the measurement and evaluation according to the measurement object and the report setting in the measurement control message, generates a measurement report according to the measurement result and reports the same to the network side and at that time the Reported measurement report is called normal measurement report. The network side performs an automatic switch judgment according to the measurement report reported by the UE.
    [0013] In order to provide a higher data rate for mobile users, the long-term evolution advance (abbreviated as LTE-A) proposes carrier aggregation technology (abbreviated as CA) and its aim is to provide bandwidth bandwidth for the UE that has matching capacity and enhance the peak rate of the UE. In LTE, the maximum downlink transmission bandwidth supported by the system is 20 MHz and carrier aggregation must aggregate two or more component carriers (abbreviated as CC) to support a transmission bandwidth greater than 20 MHz and which does not exceed 100 MHz. The LTE-A UE with carrier aggregation capability may transmit/receive data over multiple component carriers and the next UE is such a UE unless specifically stated otherwise. In LTE-A, after having entered the connected state, the UE can communicate with the source base station via multiple component carriers (such as CC1 and CC2) simultaneously, the base station will assign a primary component carrier (abbreviated as PCC) to the UE through explicit configuration or according to the protocol agreement, other component carriers are called secondary component carriers (abbreviated as SCC), the serving cell in the DL PCC is called the primary cell (abbreviated as Pcell) and the serving cell in the DL SCC is called the secondary cell (abbreviated as Scell).
    [0014] The automatic switching process in LTE-A is the same as in LTE. The source base station sends measurement control to the UE which is under connected state, the UE performs the measurement and reports a measurement report, the source base station decides to perform automatic switching in combination with practical situations according to the measurement report. measurement received, selects the target primary cell, and sends an auto-change request message to the target base station to which the target primary cell belongs, with the capacity information, AS layer configuration information, RRM configuration information, and context of the UE that are transmitted therein, the target base station responds to an autochange request response message to the source base station after it has performed processing such as resource reservation and so on, with the command information of auto-switch to the UE that is transmitted therein, auto-switch command information includes primary target cell information (and This target primary cell may be different from the one in the autochange request message) and may also include one or more secondary cells, the UE receives the autochange command (i.e., RRC reset) from the source base station and the UE sends a full auto switch command to the target base station after the target primary cell performs random access and completes the same.
    [0015] In order to coordinate the target base station to configure one or more secondary cells, the auto change request message sent by the source base station to the target base station will further include a list of optimal cells and perform signal quality (such as the received strength of reference signal (abbreviated as RSRP)) and received quality of reference signal (abbreviated as RSRQ) of those cells and this list of ideal cells and the signal quality of the cells in the list are called additional measurement results . The source base station at least selects one optimal cell for each frequency in the available measurement report to form this list of optimal cells. The target base station may configure the Scell for the UE as per the above list and of course the configured Scell may not be a cell in the above list.
    [0016] During the measurement process in the relevant technique, the terminal has to transmit additional measurement results each time it reports the measurement report, which inevitably takes up a large amount of air interface resources and causes greater system overhead. Summary of the Invention

Detailed description of the embodiments
    [0036] The present invention will be described in detail below with reference to the accompanying drawings together with the embodiments. It should be noted that the embodiments of the present application and the resources in the embodiments may be combined with each other if there is no conflict.
    [0037] This embodiment provides a method for reporting additional measurement results and Figure 2 is a flowchart of a method for reporting additional measurement results in accordance with embodiments of the present invention and as shown in Figure 2 , and the method comprises the following steps:
    [0038] Step S202: a terminal receives a notification from a base station, where the notification indicates whether or not the terminal should report an additional measurement result; and
    [0039] Step S204: The terminal reports an additional measurement result according to the notification from the base station.
    [0040] In the above method, the terminal can report additional measurement results under the control of the base station, i.e. report if the base station notifies that the report is required and not report if the base station notifies that the report is not If necessary, this method enables the base station to control whether or not the terminal reports additional measurement results, which reduces the possibility of the terminal reporting additional measurement results, thus reducing system overhead.
    [0041] In order to be able to generate convenience for the base station to analyze and process the measurement results, the terminal can sort them in a certain order and then report them to the base station and figure 6 is a preferred flowchart of a method to report additional measurement results in accordance with embodiments of the present invention, and as shown in figure 6, such a method may comprise the following steps:
    [0042] Step S602: a terminal receives a notification from a base station, where the notification indicates whether or not the terminal should report an additional measurement result; and
    [0043] Step S604: In response to the notification from the base station, the terminal classifies a plurality of cells at a current frequency according to a predetermined classification mode and selects an optimal cell at the current frequency based on the classification result and reports the additional measurement result.
    [0044] The above predetermined sorting mode, for example, could be: sorting according to RSRP and sorting according to RSRQ and the default sorting mode is determined by one of the following: an order of measurement tasks that the base station configures to trigger the measurement report; an order notified by the base station; and an order designated by the protocol.
    [0045] During its practical application, the terminal can report the additional measurement result in an additional measurement result report order notified by the base station; or the terminal may also report the additional measurement result in a designated order in a configuration of a measurement task that triggers a measurement report; or the terminal reports the additional measurement result in an order designated by the protocol.
    [0046] During the control, the base station can adjust or select the control accuracy by itself and during its practical application, different control accuracies can be selected according to different situations or according to the protocol provisions and so on. Control accuracies are illustratively exemplified: (1) the base station notifies the terminals of whether or not to report the additional measurement result with the use of an individual terminal as a unit, through this method, the control accuracy is controlled to the single terminal level, i.e. different reporting strategies are configured according to different terminal configurations (the possibility to report additional measurement result), this method is relatively simple and the control overhead is relatively small ; and it should be noted that in this situation designating which endpoints can be processed according to the protocol designation, for example, the endpoint supporting carrier aggregation needs to transmit, at that time, the base station does not need to notify the endpoint about the possibility whether or not to report the additional measurement result, due to the fact that the protocol has already designated the endpoints and both the base station and the endpoint are aware of it; or, the base station can notify the terminal that it needs to report the additional measurement result via an RRC reset command message. (2) the base station notifies the terminals on whether or not to report the additional measurement result using one or multiple measurement tasks as a unit, through this method, the control accuracy is controlled to the level of measurement task, i.e. different reporting strategies are configured according to different measurement tasks (the possibility to report the additional measurement result), this method can precisely control the possibility of the terminal to report the additional measurement result and can reduce generating unnecessary reports as much as possible, thus further reducing air interface overhead. In this situation, the base station can notify the endpoint of the particular measurement task that it needs to report the additional measurement result when it configures the measurement task via the RRC reset command message, or the base station can notify the endpoint via a measurement task identification list that needs to report additional measurement result. (3) the base station notifies the terminals of whether or not to report the additional measurement result using one or multiple measurement events as a unit, through this method the control accuracy is controlled to the level of measurement event, i.e. different reporting strategies are configured according to different measurement events (the possibility to report the additional measurement result), this method can precisely control the possibility of the terminal to report the additional measurement result and can reduce generating unnecessary reports as much as possible, thus further reducing air interface overhead. It should be noted that in this situation, to particularly designate that the measurement event(s) can be processed according to the protocol designation, at that time, the base station need not designate that this control is for each measurement event when it notifies the terminals about whether or not to report the additional measurement result, as the protocol has already designated the particular measurement event, which is known by both the base station and the terminal; or the base station can notify the terminal of the particular metering event via the RRC reset command message, at that time, the base station only needs to instruct the terminal to report that metering event, which particularly can be implemented by adding an indication bit in the measurement task configuration information transmitted in the RRC reconfiguration command message or may be deployed by the base station which sends a measurement event identification list that needs to report additional measurement result, and preferably, the terminal can also be notified which measurement event is not required to report, so the base station control can be more flexible.
    [0047] Preferably, the base station can notify the terminal about whether or not to report the additional measurement result by one of the following ways: (1) notify the terminal about whether or not to report an additional measurement result via the value of the indication bit transmitted in a predetermined message, for example, the value of the indication bit being 1 represents reporting an additional measurement result and the value thereof being 0 represents not reporting an additional measurement result; and (2) notify the terminal as to whether or not to report an additional measurement result by determining whether or not to execute an indication bit in a predetermined message, for example, the predetermined message that includes that indication bit represents reporting and which does not include represents not reporting and this method may achieve backward compatibility.
    [0048] Preferably, the above default message can be used to configure the RRC reset command message from a measurement task to the terminal and can also be used to configure other RRC reset command messages except to configure the RRC reset message. RRC reset command from a measurement task to the terminal.
    [0049] According to the NTT simulation result, these carriers with approximate signal quality have the best aggregation effects. Therefore, in order to reduce signaling overhead, the terminal can only include cells where the signal quality phase differences between ideal cells at other frequencies and ideal cells in normal measurement reports are within a predetermined deviation. and their signal quality. During its practical deployment, in the additional measurement result the terminal can control the cell signal quality reported by to meet the following condition: Cell reported signal quality > (optimal cell signal quality in a normal measurement report - deviation default). In this case, the predefined deviation can be provisioned by the protocol and can also be sent to the terminal through an RRC signaling.
    [0050] Each time it reports the measurement report, the terminal needs the measurement result of the serving cell, including the primary cell and the secondary cell. The signal quality of the secondary cell can also be used as an additional measurement result, thus, in the organization of information element, the signal quality of the secondary cell and the additional measurement result transmitted by the terminal can be put together, i.e. that is, the additional measurement result reported by the terminal may also include the secondary cell measurement result.
    [0051] During its practical implementation, the additional measurement result is useful only when an automatic change occurs, but not every measurement report reported serves for automatic change, therefore, an additional measurement result is transmitted in it each time reports the measurement report, in many cases these measurement results are useless, but take up air interface resources, so in order to better meet the needs of partial deployment, the base station can use the following control modes: in the situation where that needs to perform automatic switching, the terminal is instructed to report an additional measurement result; and in the situation where it does not need to perform automatic change, the terminal is instructed not to report an additional measurement result. In this way, auto-change needs can be met in the situation where the number of terminal reports can be reduced as much as possible.
    [0052] Figure 3 is a structural block diagram of a system for reporting additional measurement results in accordance with embodiments of the present invention and as shown in Figure 3, the system comprises a base station 32 and a terminal 34 , wherein the base station 32 includes: a notification module 36 that is configured to notify the terminal 34 as to whether or not to report an additional measurement result; and the terminal 34 includes: a reporting module 38 coupled to the notification module 36 which is set to report an additional measurement result in accordance with the notification from the base station 32.
    [0053] Preferably, the reporting module 38 can be configured to sort a plurality of cells at a current frequency according to a predetermined sorting mode, select an optimal cell at the current frequency based on the sort result, and report the result of additional measurement.
    [0054] Figure 4 is a structural block diagram of a device for reporting additional measurement results in accordance with embodiments of the present invention and as shown in Figure 3, the device comprises a receiving module 40 and a receiving module 40. report 42.
    [0055] The receiving module 40 is configured to receive a notification from a base station, where the notification indicates whether or not the terminal should report an additional measurement result; and
    [0056] Reporting module 42 is configured to, in response to notification from the base station, classify a plurality of cells at a current frequency according to a classification mode, select an optimal cell at the current frequency based on the classification result and report the additional measurement result.
    [0057] Preferably, the reporting module 42 is further configured to report the additional measurement result in an additional measurement result reporting order notified by the base station; or the reporting module is configured to report the additional measurement result in a designated order in a configuration of a measurement task that triggers the measurement report; or the reporting module is configured to report additional measurement result in an order designated by the protocol.
    [0058] Embodiments 1 to 4 described below summarize the technical solution of the multiple preferred embodiments and embodiments 1 to 4 are based on the scenario shown in figure 5. Embodiment 1
    [0059] As shown in figure 5, UE1 configures cell1 to F1 and cell2 to F2 during communication, where cell1 is Pcell and cell2 is Scell and the base station configures the measurement task for UE1 via of an RRC reset command and an indication of the possibility to report the additional measurement result is set in that RRC reset command for each task, where the indication has two values of TRUE and FALSE, where TRUE represents that p result additional measurement result needs to be reported and FALSE represents that the additional measurement result does not need to be reported. For backward compatibility purposes the indication can only have a value of TRUE, if there is no indication then it is considered that the additional measurement result does not need to be reported and if that indication exists then its value is TRUE which represents that the result additional measurement needs to be reported. Measurement task setup is as follows: MID = 1, MO = F1, RC = A2, report RSRP and RSRQ, sort according to RSRP, possibility to report additional measurement result = FALSE MID = 2, MO = F2 , RC = A2, report RSRP and RSRQ, sort according to RSRP, possibility to report additional measurement result = FALSE MID = 3, MO = F1, RC = A3, report RSRP and RSRQ, sort according to RSRP, possibility to report additional measurement result = TRUE MID = 4, MO = F2, RC = A6, report RSRP and RSRQ, sort according to RSRP, possibility to report additional measurement result = TRUE
    [0060] UE1 moves to point A and the measurement report reported is as shown in Table 1: Table 1


    [0061] After receiving the measurement report reported by UE1, base station 1 decides to switch the UE to Cell4 in F2 according to the measurement report of MID=4 with reference to the measurement report of MID=3 and transmits the list of ideal cells in an autochange setup command, including Cell4 in F2 and Cell3 in F1.
    [0062] In the above embodiments, if the following measurement task is still included in it: MID = 5, MO = F3, RC = A3, report RSRQ, sort according to RSRQ and possibility to report to additional measurement result = TRUE, then the measurement results of the ideal cells at other frequencies (such as F3) are transmitted in them when reporting the measurement report of MID = 3, select the ideal cell according to the classification mode of that measurement task (MID = 3) is RSRP. Alternatively, selecting the optimal cell according to this measurement task classification mode (MID = 5) of other frequencies (such as F3) is RSRQ. If the protocol has designated, or the base station additionally directs the terminal to select the optimal cell according to RSRP through RRC reconfiguration.
    [0063] If MO = F3 and other measurement tasks are still configured, MID = 6, MO = F3, RC = A4, report RSRP, sort according to RSRP and possibility to report additional measurement result = TRUE, the results measurement of the ideal cells at other frequencies (such as F3) are transmitted at the same as the measurement report of MID = 3, preferably select the ideal cell according to RSRP in accordance with the classification mode of the measurement tasks in other frequencies such as the F3 frequency measurement task (MID = 5 and 6). Or, preferably select the optimal cell according to RSRP according to the contents (such as RSRP and RSRQ) reported by designated additional measurement results.
    [0064] If additional measurement result is required to be classified, the classified signal quality may be in accordance with the classification mode (such as RSRP) of the measurement task (such as MID=3) that triggers the measurement report , or may be designated by the protocol (such as RSRP), or the base station notifies the UE via an RRC reconfiguration command (such as RSRP), or preferably sort according to RSRP (secondly according to RSRQ ) in accordance with the contents (such as RSRP and RSRQ) reported by designated additional measurement results. In this embodiment, reporting the measurement report of MID = 3 requires sorting the ideal cells into F2 and F3 based on this principle.
    [0065] Regarding the above setting of the possibility to report additional measurement result, the base station can also notify the terminal of a measurement task identification list that reports an additional measurement result and the additional measurement result needs to be transmitted in the same when reporting the measurement report of the measurement task ID in this list. Embodiment 2
    [0066] As shown in figure 5, UE2 configures cell1 to F1 and cell2 to F2 during communication, where cell1 is Pcell and cell2 is Scell and the base station configures the measurement task for UE2 via of an RRC command, at the same time, the base station notifies the terminal that the A3 event measurement report needs to transmit an additional measurement task via this RRC reset command or another RRC reset command and an indication of the possibility to report the additional measurement result is configured for each task, where the indication has two values of TRUE and FALSE, where TRUE represents that the additional measurement result needs to be reported and FALSE represents that the additional measurement result does not needs to be reported. For backward compatibility purposes the indication can only have a value of TRUE, if there is no indication then it is considered that the additional measurement result does not need to be reported and if such an indication exists then its value is certainly TRUE which represents that the Additional measurement result needs to be reported. Additionally, the protocol designates the contents (such as RSRP) reported by the additional measurement result, or the base station notifies the UE of the contents (such as RSRP) reported by the additional measurement result via an RRC reset command.
    [0067] The measurement task configuration is as follows: MID = 1, MO = F1, RC = A2 MID = 2, MO = F2, RC = A2 MID = 3, MO = F1, RC = A3 MID = 4, MO = F2, RC = A6
    [0068] UE2 moves to point A and the measurement report reported is as shown in Table 2: Table 2


    [0069] After receiving the same, base station 1 decides to switch the UE to Cell4 in F2 according to the measurement report of MID=4 with reference to the measurement report of MID=3 and transmits the list of ideal cells in an autochange setup command, including Cell4 in F2 and Cell3 in F1.
    [0070] The above event A3 measurement report needs to transmit additional measurement results, which can be assigned by the protocol or the base station notifies the UE that the related event when it needs to transmit additional measurement results is A3 via an RRC reconfiguration command, or the base station notifies the UE that it needs to transmit additional measurement results in the configuration information (such as RC configuration) of the measurement task while configuring the measurement task to the UE via of an RRC reset command. Other events (such as A5 and so on) may also be assigned. Additionally, multiple events (such as A3 and A5) can also be instructed that they need to report additional measurement results.
    [0071] When reporting the measurement report of MID = 3, it needs to report the measurement results of Cell1 and Cell2 and also needs to report the measurement results of Cell3 and Cell4. As Cell1 is Pcell and the equivalent of the serving cell in R8/9 is reported in the measurement result of the original serving cell, the measurement results of other cells (such as Cell2/Cell3 and Cell4) can be reported according to the structure shown in Table 3. Table 3


    [0072] The classification mode of additional measurement results can be determined via a new indication, i.e. the base station notifies that additional measurement results are reported in accordance with RSRP or RSRQ via a reset message of RRC and the ideal is anticipated. Or, use the measurement task setting that triggers the measurement report again, such as the measurement report triggered by the measurement task of MID = 3, the sort mode to transmit the additional measurement results is according to the mode of classification to report the measurement result of MID = 3, that is, the Trigger Quantity setting in RC. Or sort according to the contents (i.e. RSRP in that embodiment) reported by the designated additional measurement results. Embodiment 3
    [0073] As shown in figure 5, UE1 and UE2 set cell1 to F1 and cell2 to F2 during communication, where cell1 is Pcell and cell2 is Scell and the base station sets the measurement task to UE1 and UE2 via an RRC reset command, at the same time, the base station notifies the measurement report of UE1 that it is necessary to transmit an additional measurement result via the RRC reset command and does not notify the measurement report of UE2 that it is necessary to transmit an additional measurement result or notifies the measurement report of UE2 that it is not necessary to transmit an additional measurement result and an indication of the possibility to report the additional measurement result is configured for each task, where the indication has two values of TRUE and FALSE, where TRUE represents that the additional measurement result needs to be reported and FALSE represents that the additional measurement result does not need to be reported. ado. For backward compatibility purposes the indication can only have a value of TRUE, if there is no indication then it is considered that the additional measurement result does not need to be reported and if such an indication exists then its value is certainly TRUE which represents that the Additional measurement result needs to be reported. If they judge according to the capability of the UE, how both UE1 and UE2 support carrier aggregation, then both UE1 and UE2 need to transmit additional measurement results when reporting measurement reports. The measurement task setup is as follows:
    [0074] MID = 1, MO = F1, RC = A2
    [0075] MID = 2, MO = F2, RC = A2
    [0076] MID = 3, MO = F1, RC = A3
    [0077] MID = 4, MO = F2, RC = A6
    [0078] UE1 moves to point A and the measurement report reported is as shown in Table 4: Table 4


    [0079] After receiving the same, base station 1 decides to switch the UE to Cell4 in F2 according to the measurement report of MID=4 which includes the signal quality of Cell3 and Cell4 and transmits the list of ideal cells in an autochange setup command, including Cell4 in F2 and Cell3 in F1.
    [0080] UE2 moves to point A and the measurement report reported is as shown in Table 5: Table 5

    [0081] After receiving the same, although the additional measurement report is not reported, base station 1 decides to switch the UE to Cell4 in F2 according to the MID=4 report with reference to the MID=3 measurement report and transmits the list of ideal cells in an autochange setup command, including Cell4 in F2 and Cell3 in F1. Embodiment 4
    [0082] As shown in figure 5, UE1 configures cell1 to F1 and cell2 to F2 during communication, where cell1 is Pcell and cell2 is Scell and the base station configures the measurement task for UE1 via of an RRC reset message. At the same time, the base station notifies the UE via an RRC reconfiguration message that it only needs to transmit the cell in which the cell signal quality is ideal on other frequencies (i.e. RSRP in this embodiment) is higher than (optimal cell signal quality in measurement report -3dB), the above 3dB can be assigned by protocol or determined by base station negotiation. The signal quality compared above can be sent to the UE by the base station by means of an RRC reconfiguration command which is RSRP or RSRQ and can also be assigned by the protocol to RSRP or RSRQ. The measurement task configuration is as follows: MID = 1, MO = F1, RC = A2, the possibility to report the additional measurement result = FALSE MID = 2, MO = F2, RC = A2, the possibility to report the additional measurement result = FALSE MID = 3, MO = F1, RC = A3, the possibility to report the additional measurement result = TRUE MID = 4, MO = F2, RC = A6, the possibility to report the additional measurement result = TRUE
    [0083] Base stations 1 and 3 negotiate the determination that the list of ideal cells transferred in the autochange setup command only needs to transfer a cell that is higher than the signal quality of the target PCell by subtracting 3dB. The above 3dB can also be designated by the protocol.
    [0084] UE1 moves to point B and the measurement report reported is as shown in Table 6: Table 6


    [0085] After receiving the same, base station 1 decides to switch the UE to Cell5 in F1 according to the report of MID=4 with reference to the measurement report of MID=3 and transmits the list of ideal cells in the command of autochange preparation, including Cell5 in F1 and not including Cell6 in F2, due to the fact that its signal quality is lower than that of Cell5 by -3dB.
