Background
Ensuring service continuity for mobile subscribers is a basic function of cellular mobile communication systems, and handover of a mobile station serving cell is a primary means of ensuring service continuity. In order to facilitate switching of a UE (User Equipment), a system needs to configure an adjacency relation for each cell, so that a network side notifies neighboring cell information to the User Equipment; and the network side indicates the user equipment to switch to a certain adjacent cell according to the reported measurement result.
The neighboring cells around a cell are not only related to the cell distance, but also closely related to the radio environment in which the cell is located. Due to the complex wireless environment, especially the dense urban environment of high-rise buildings, it is difficult to exactly judge which neighboring cells should be configured for a certain cell at the initial stage of network planning. Some systems are added with a cell or the property of the cell is changed, and the adjacent relation of the cell is not updated in time; or the change of the environment, the omission of network planners and the like can cause the update of the information of the adjacent regions to be untimely. This will cause the user equipment not to be able to 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 is dropped. Therefore, an ANR (Automatic neighbor relation Function) topic is introduced into the 3GPP (3rd generation partnership project) conference, but there is no specific method for controlling the UE to perform measurement reporting.

Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 1 is a flowchart of a method of controlling a user equipment to perform measurement according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S102, RNC informs UE to carry out ANR measurement and indicates that the UE measurement reporting mode is periodic reporting;
and step S104, the UE carries out ANR measurement and periodically reports the measurement result according to the indicated measurement reporting mode.
By the method, the UE can perform ANR measurement under the control of the RNC, and the RNC can also indicate a measurement reporting mode adopted by the UE when the measurement result is reported, so that the real-time performance and the accuracy of the measurement information are controlled by adjusting the reporting mode according to the self requirement.
In practical application, the RNC may notify the UE of performing the ANR measurement by sending a notification message for notifying the UE of performing the ANR measurement to the UE, and notify the UE of the reporting mode of performing the ANR measurement by carrying an indication of the reporting mode in the notification message, that is, the notification message may carry indication information that the measurement reporting mode is periodically reported. When the RNC sends the ANR measurement notification message, the RNC carries indication information for specifying a reporting mode to indicate the mode adopted by the UE to report the measurement result, and the reporting mode can be changed according to different conditions, so that the compatibility and the application flexibility are improved.
Specifically, the method for indicating the UE measurement reporting mode to be periodic reporting may include, but is not limited to, the following methods:
(1) the notification message carries a cell (the cell may be newly added) whose value is reported as a cycle, and carries a cell (the cell may be newly added) whose length includes the cycle.
(2) An information element (the information element can be newly added) is carried in the notification message and represents the length of the periodic report.
Preferably, the notification message may also carry physical quantities to be measured, for example, the physical quantities may include but are not limited to at least one of the following: common pilot Channel chip energy to band-limited white Noise spectral density (CPICH Ec/N0 for short), Common pilot Channel Received Signal Code Power (CPICH RSCP for short), Primary Common Control Physical Channel Received Signal Code Power (Primary Common Control Physical Channel Received Signal Code Power, Primary CCPCH RSCP for short), and slot Signal Code Power Interference (slot Interference on Signal Code Power loss, slot Interference for short). The method for carrying the physical quantity to be measured in the ANR measurement notification message can indicate the UE to measure the physical quantity in real time, so that the measurement is more targeted, the application flexibility is higher, and the working efficiency can be greatly improved. The physical quantities listed above reflect different states of the cell, and one or more of them may be selected for measurement according to different situations in the specific implementation process, or of course, they may be expanded to select more physical quantities for measurement.
After the notification message carries the above information, the UE performs ANR measurement, and the process of periodically reporting the measurement result according to the indicated measurement reporting mode may include: the UE measures the physical quantity to be measured carried in the notification message; and the UE carries the measurement result in the measurement report to be reported periodically, wherein the interval between two adjacent reports is equal to the length of the reporting period carried in the notification message.
The above-mentioned measurement report is a form of embodying a measurement result, which may contain information of a cell and may optionally include a specific value of a measured physical quantity. In a specific implementation, the Measurement Report may be carried in an Additional Measurement Report (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: an initial direct transfer message (INITIALDIRECT TRANSFER), a MEASUREMENT REPORT (MEASUREMENT REPORT), or a radio network control CONNECTION REQUEST message (RRC CONNECTION REQUEST), an UPLINK direct transfer message (UPLINK DIRECT TRANSFER), a cell update message (cell update). The additional measurement report is a newly added message, defined as an additional measurement report, and is specifically used for reporting the measurement result. The UE may also report the measurement result using an existing RRC message, and the actually available message includes, but is not limited to, the above-listed RRC message.
After the UE performs ANR measurement and periodically reports the measurement result according to the indicated measurement reporting mode, the RNC can perform switching judgment and/or neighbor cell configuration update according to the measurement result, so that the RNC takes the periodically reported measurement result as the basis of the switching judgment to perform accurate switching judgment; the RNC may also use the measurement result reported periodically as a basis for updating the neighboring cell configuration, so as to update the neighboring relationship of the cell in time, ensure the continuity of the user call, and improve the quality of service (Qos) of the user.
The RNC makes a handover decision according to the measurement result in the following manner: the RNC counts the cell information in the measurement result, and if the number of times that the cell information of a certain cell is reported reaches a first threshold value, the cell is determined to be a target cell for switching; the RNC updating the neighbor configuration according to the measurement result may be performed in the following manner: and the RNC counts the cell information in the measurement result, if the reported times of the cell information of a certain cell reaches a second threshold value, the cell is determined to be configured as a neighboring cell, the neighboring cell is reported to the network management system, and the neighboring cell is automatically updated.
The notification message employed above may include, but is not limited to, one of the following: the system broadcasts messages, measurement control messages, or can be a custom message (a new message in addition to the existing message types). In a specific implementation, the ANR measurement notification message may be sent in the form of a system broadcast message or a measurement control message, for example: the ANR Measurement notification Message may be transmitted in a newly added recording Message (Logging Message) such as the system information block 11(SIB11), the system information block 11bis (SIB11bis), the system information block 12(SIB12), and the Measurement Control command (Measurement Control).
