BACKGROUND OF THE INVENTION Guaranteeing service continuity of mobile users is a basic function of a cellular mobile communication system, and handover of a mobile station serving cell is a primary means of ensuring service continuity. In order to facilitate the handover of the user equipment (UE), the system needs to configure the adjacency relationship for each cell, so that the network side notifies the neighboring area information to the user equipment, and the user equipment measures the neighboring area according to the neighboring area information and reports the measurement result. The network side then instructs the user equipment to switch to a neighboring area according to the reported measurement result. The neighboring areas around a certain cell are not only related to the distance of the cell, but also closely related to the wireless environment in which the cell is located. Due to the intricacies of the wireless environment, especially in the dense urban environment of high-rise buildings, it is difficult to determine exactly which neighboring areas should be configured in a certain area in the initial stage of network planning. There are also some new ones that change the cell or cell attribute in the system, do not update the neighbor relationship of the cell in time, or change the environment, omission of network planners, etc., which will cause the neighboring area information to be updated in time. In this way, the user equipment cannot switch to other cells in time, and the load of the cell is too high, the signal quality of the cell is deteriorated, the interference is serious, or the user drops the call. Therefore, the AR (Automatic Neighboring Relationship Function) topic was introduced in the 3GPP (3rd Generation Partnership Project) conference.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. 1 is a flow chart of a method of controlling user equipment to perform measurements in accordance with an embodiment of the present invention. As shown in FIG. 1 , the method includes: Step S102: The RNC notifies the UE to perform the ANR measurement, and indicates the measurement reporting parameter to the UE, where the measurement reporting parameters include: a preset duration, an ANR measurement threshold, and a reported maximum cell. In the step S104, the UE performs the ANR measurement, and the measurement result that meets the preset relationship with the ANR measurement threshold (which may be determined according to the actual situation, for example, greater than or equal to or equal to) is periodically reported according to the preset duration, where each The measurement result of the M cells is reported twice, and M is not greater than the maximum number of cells reported. Through the above method, the UE can perform ANR measurement under the control of the RNC, and the RNC can also indicate the measurement reporting mode used by the UE when reporting the measurement result, so as to control the real-time measurement information by adjusting the reporting manner according to its own needs. Sex and accuracy. In the method, the indication of the reporting mode is represented by the length of the period (the preset duration), the threshold of the ANR measurement, and the maximum number of cells reported, wherein the length of the period indicates that the interval for reporting the measurement report by the UE cannot be less than The length of the period, the threshold of the ANR measurement indicates that the measured value of the ANR measurement by the UE needs to satisfy a certain relationship with the threshold. The maximum number of reported cells indicates that the measurement report reported by the UE cannot exceed the value. By controlling the maximum number of reported cells, the RNC can prevent the problem that the processing of the UE and the RNC is too heavy due to too many cells being reported at one time, and can also simplify the complexity of the subsequent decision or processing by the RNC according to the measurement result. Moreover, the RNC can prevent the measurement report from being too frequent by controlling the minimum period of the report. In addition, the RNC can control the condition that the reported cell meets by controlling the threshold of the ANR measurement, and only the measurement result corresponding to the cell satisfying the specific condition is obtained. In order to optimize the performance of the system, the specific condition can be made to be a meaningful cell for the handover decision or the neighboring configuration update. In an actual application, the RNC may notify the UE to perform the ANR measurement by sending a notification message for notifying the UE to perform the ANR measurement to the UE, and notify the user equipment to perform the ANR measurement reporting by carrying the measurement reporting parameter in the notification message. Related parameters. The reporting parameters can be changed according to different situations, thereby improving compatibility and application flexibility. Specifically, the manner of indicating the measurement reporting parameter to the UE may include, but is not limited to, one of the following:

(1) Three cells are configured in the notification message, indicating the preset duration, the threshold of the ANR measurement, and the maximum number of reported cells.

(2) Instructing the maximum number of cells reported by the RNC and the UE to be reported, SP, defining a macro value to indicate the maximum number of cells to be reported, and configuring two cells in the notification message, respectively carrying the preset duration and the ANR measurement. Threshold. Preferably, the threshold of the ANR measurement included in the measurement report parameter is a threshold of the ANR measurement corresponding to the physical quantity to be measured, where the physical quantity may include but not be limited to the following. At least one of: Common Pilot Channel Energy per chip Noise Ratio (CPICH Ec/N0), common pilot channel received signal code power (Common Pilot) Channel Received Signal Code Power (CPICH RSCP), Primary Common Control Physical Channel Received Signal Code Power (Primary CCPCH RSCP), Time Slot Signal Code Power Interference Path Loss (Timeslot Interference) On Signal Code Power Pathloss, referred to as Timeslot ISCP Pathloss). By carrying the physical quantity to be measured in the ANR measurement notification message, the physical quantity of the UE can be measured in real time, so that the measurement is more targeted, the application is more flexible, and the working efficiency can be greatly improved. The physical quantities enumerated above reflect the different states of the cell. In the specific implementation process, one or more of the cells may be selected for measurement according to different situations. Of course, it may also be expanded to select more physical quantities for measurement. It should be noted that, when the RNC notifies the user equipment of the physical quantity to be measured, the threshold of the notified ANR measurement may match the physical quantity to be measured, that is, the threshold of the ANR measurement may be the to-be-measured The reported value of the physical quantity. However, those skilled in the art should understand that the threshold of the ANR measurement can also be carried independently of the physical quantity to be measured, that is, the threshold of the ANR measurement can be carried only, and the physical quantity to be measured is not indicated, at this time, the terminal The measurement can be performed using the physical quantity specified by the system, and then reported if the measured result satisfies the preset condition compared with the threshold. After the information is carried in the notification message, the UE performs the ANR measurement, and the process of periodically reporting the measurement result that the threshold of the ANR measurement meets the preset relationship according to the preset duration may include: the physical quantity to be measured carried by the UE in the notification message Performing the measurement; the UE carries the measurement result that the threshold corresponding to the ANR measurement corresponding to the physical quantity to be measured meets the preset relationship in the measurement report, and periodically reports according to the preset duration, which is equivalent to whether the reporting condition of the UE is satisfied. The decision is to report the measurement report to the radio network controller when the reporting condition is met. The process of periodically reporting according to the preset duration may include:

(1) The periodic reporting is performed by using the preset duration as the reporting period. In this case, the physical quantity measured by the UE is greater than or equal to the threshold of the ANR measurement carried in the notification message, and the interval between the two reporting needs to be greater than or equal to the notification message. The length of the period carried in. Or,

(2) The time interval for reporting the two adjacent reports is not less than the preset duration. In this case, the physical quantity that needs to be measured when the UE performs periodic reporting is greater than or equal to the threshold of the ANR measurement carried in the notification message. It can be seen that the decision to report the condition must satisfy both the period plus the condition of the event. For example, the physical quantity measured by the UE is greater than or equal to the threshold of the ANR measurement carried in the notification message, and the interval between the two reports needs to be greater than or equal to the length of the period carried in the notification message; or, when the UE performs periodic reporting The physical quantity to be measured is greater than or equal to the threshold of the ANR measurement carried in the notification message for reporting. When the user equipment performs the ANR measurement, the UE measures the measured physical quantity included in the notification message, performs the sorting according to the measured cell signal quality, and periodically reports the cell information with good cell signal quality to the radio network controller, and reports the measurement. The interval of the report, such as the length of the period in the message, and the number of cells reported The maximum number of cells reported by the UE specified in the notification message is not exceeded. In a specific implementation, the following preferred implementation manners are used to enable the UE to control the number of reported cells: When the UE carries the measurement result in the measurement report for reporting, the UE may use the measurement result according to the cell signal quality from large to small. If the number of measured cells is greater than the maximum number of reported cells (denoted as N), the measurement results of the first N cells in the ranking result are carried in the measurement report for reporting. The measurement report mentioned above is a form of reflecting the measurement result, which may contain information of the cell, and may also optionally include a specific value of the measured physical quantity. In a specific implementation, the measurement report may be carried in an Additional Measurement Report, or reported in an existing RRC message. When carried in an existing RRC (Radio Resource Control) message, the RRC message may be one of the following: INITIAL DIRECT TRANSFER Measurement Report (MEASUREMENT REPORT) Wireless Network Control Connection Request message (RRC) CONNECTION REQUEST ), UPLINK DIRECT TRANSFER, CELL UPDATE. The above additional measurement report is a new message, defined as an additional measurement report, dedicated to reporting the measurement results. The UE may also report the measurement result by using an existing RRC message, and the actually available message includes but is not limited to the RRC message listed above. After the ANR measurement is performed by the UE, and the measurement result is periodically reported according to the indicated measurement reporting manner, the RNC may perform a handover decision according to the measurement result and/or perform a neighbor configuration update, so that the RNC uses the periodically reported measurement result as the measurement result. The basis of the handover decision is made to perform an accurate handover decision. The RNC can also use the periodically reported measurement result as the basis for the neighbor configuration update, update the neighbor relationship of the cell in time, ensure the continuity of the user call, and improve the user. Quality of Service (Qos for short). The RNC can perform the handover decision according to the measurement result in the following manner: The RNC performs statistics on the cell information in the measurement result. If the number of times the cell information of a cell is reported reaches the first threshold, it is confirmed that the cell is used as the handover. The RNC performs the neighboring area configuration update according to the measurement result in the following manner: The RNC performs statistics on the cell information in the measurement result. If the number of times the cell information of a cell is reported reaches the second threshold, it is confirmed. The cell is configured as a neighboring area, and the neighboring area is reported to the network management system, and the neighboring area is automatically updated. The notification message adopted above may include, but not limited to, one of the following: a system broadcast message, a measurement control message, or a customized message (in addition to an existing message type, a new type of message) . In a specific implementation process, the ANR measurement notification message may be sent in the form of a system broadcast message or a measurement control message, for example: system information block 11 (SIB11), system information block llbis (SIBllbis), system information block 12 (SIB12), The measurement control command (Measurement Control) or the new logging message (Logging Message) sends an AR measurement notification message. The following is a detailed description of the processing after the radio network controller receives the ANR measurement report reported by the UE, with reference to the example and FIG. 2 to FIG.
