Description

The present invention relates to the field of communications, and in particular to a method and apparatus for reporting neighboring cell relationship measurement results. BACKGROUND OF THE INVENTION With the increase in the number of operators of cellular mobile communication system operators and the increase in service demands of users, the scale of cellular networks is continuously expanding, and the number of base stations is increasing, and various types of cellular mobile communication systems are continuously deepened in cooperation with each other. Concomitantly, the management and maintenance of the neighborhood relationship of the cells in the cellular network becomes more and more cumbersome, and the operators expect that the purely manual neighbor relationship management in the past can be automated by the system. Without exception, UTRAN (Universal Terrestrial Radio Access Network) network operators are eager to automate the management of their neighbors in the network cell. As shown in FIG. 1 of the specification, in the UTRAN network, the UTRAN includes two basic network elements: an RNC (Radio Network Controller) and a NodeB (Base Station). The neighbor relationship between many cells under hundreds of NodeBs will change dynamically with the needs of network planning optimization and the changes in the wireless environment. In a UTRA network, the correct neighborhood relationship in a small interval is very important for network performance. For example: to achieve mobile users, the terminal UE optimal switching, to ensure its service continuity, to help the network achieve load balancing, capacity allocation, energy saving and other multiple purposes. In the past, under the manual manual neighboring arrangement, the network side notifies the neighboring cell relationship that has been configured in advance by the system broadcast message or the proprietary control message, and the UE further stores and utilizes the received cell neighbor relationship. However, the neighbor relationship configured from the network side in advance may be outdated and cannot truly reflect the real-time neighbor relationship, which may cause the UE to switch incorrectly or even drop the call, and the network performance is generally degraded. In the UTRA system, 3GPP has introduced Automatic Neighbor Relation Functionality (ARF) in Release 10 (ReleaselO). As of the time of writing the invention patent, although the details of the URF final solution of UTRA have not been determined, the basic process architecture of the solution has been determined and disclosed. Please refer to Figure 2 of the specification of the present invention. This solution borrows the idea of MDT (Minimize Driving Test) technology, which is Log-based, referred to as Log ANR scheme. The specific process steps are shown in Figure 2, which is as follows: S201: The UE resides in a source cell under the source RNC. The source RNC selects a suitable terminal UE in the source cell to perform one or several types of ANRF measurement tasks. The choice of this suitability lies in the UE's own ANRF support capabilities, the communication status and associated environment, and so on.

S202: The source RNC performs a UE in the source cell to the previously selected ANRF task, and sends an RRC message with A R Configurations containing the ANRF measurement control configuration parameter. These ANRF configuration parameters may include: Intra-frequency neighbor unknown cell detection, and/or UTRA out-frequency neighbor unknown cell detection, and/or cross-LTE system (Inter - LTE) detection of neighboring unknown cells, detection of neighboring unknown cells in the inter-GSM system (Inter-GSM), necessary configuration information related to the four basic ANRF measurement types, such as which physical layer signal information is performed. Measurement acquisition, measurement of event-related thresholds, thresholds, offsets, neural buffers, etc., optionally also includes the acquisition of Layer 2 information on the physical layer (Layer 2 info acquisition). The UE saves the configuration parameters of these ANRFs and continues with other necessary communication behaviors.

S203: After the UE performs a certain RRC (Radio Resource Control) signaling interaction, the UE enters a state suitable for ANRF measurement, and uses the previously saved ANRF configuration parameter to be adjacent to one or more classes. Prepare for the measurement of the unknown detection cell. The states suitable for ANRF measurements may be idle state Idle, paging state URA_PCH, Cell_PCH, and so on.

S204: The UE performs a cell measurement task in a regular neighbor list related to the non-ANRF measurement task to prepare for cell reselection due to possible mobility of the UE itself or other reasons. On the other hand, the UE follows the previous ANRF. The configuration performs an ANRF measurement task, and records the measurement result (including physical layer information, optionally: layer 2 information above the physical layer) that satisfies certain conditions in the ANR table (ANR Logging Table) inside the UE. This kind of recording behavior, referred to as ANR Logging or Logging, is a core idea of MDT technology. When a cell in the normal neighbor list of the UE satisfies the cell reselection condition, the UE still reselects to the target cell in the neighbor list according to the previous mode, and is not interfered by the ANRF measurement task, that is, It is said that the ANRF measurement task is accompanied by the regular cell reselection behavior of the UE. S205: When the UE selects a target cell in a neighbor list and reselects the entry, if the UE already has valid logging content in its internal ANR table, it sends the target to the target cell. In an RRC uplink message of the RNC, it indicates that its ANRF measurement result is already owned and can be reported.

S206: After the UE performs a certain RRC (Radio Resource Control) signaling interaction, the UE enters a state suitable for reporting the ANRF measurement result, and prepares for reporting. S207: The target RNC where the target cell is located requests the UE to report the A RF measurement result by using an RRC downlink message. We call this process ANR Logging Results Retrieval.

S208: The UE reports the ANRF measurement result previously saved in the ANR table by using an RRC uplink message according to the request of the target RNC.

S209: The target RNC maintains its related Neighbor Relation Table (RT) according to the obtained ANRF measurement result. The Log ANR scheme of the UTRA system described above is relatively easy to implement and has little impact on the UE's original service and mobile behavior. However, due to the adoption of the MDT idea, it naturally inherits many of its shortcomings, as follows: The re-selected Log ANR mode can only report and report the ANR logs result to the reselected target cell Target cell instead of the source cell Source cell. If the target cell and the source cell are under the same RNC, the problem is not significant, because there is a mechanism within the RNC to maintain the neighbor relationship based on ANR Logs. However, when the reselected target cell and the source cell are under different RNCs, and even if the target cell is in another system (such as LTE, GSM), the source RNC where the source cell is located in order to obtain the latest unknown neighbor relationship of the source cell, the source The Iur interface between the RNC and the target RNC must cooperate. The Target RNC transmits the ANR logs reported by the UE in the target cell to the Source RNC in some form. This method is feasible for cross-RNC, at the cost of more Iur signaling interactions; but it is not feasible for cross-system missing, because there is no direct interface between network controllers of different systems, so the UTRA system only waits for the UE to return again. It is possible to obtain ANR Logs stored by the UE in its own UTRA cell, and this reporting delay is sometimes very large, so it brings uncertainty to the RNC to maintain the neighboring area. SUMMARY OF THE INVENTION The present invention is directed to a method and apparatus for reporting a neighbor cell relationship measurement result, which is to solve the problem that when the reselected target cell and the source cell are under different RNCs, the ANR logs result is reported to be delayed.

Preferably, the first reporting module and the second reporting module are further configured to report N neighbor cell relationship measurement results each time N neighbor cell relationship measurement results are recorded. In the preferred embodiment, the step of reporting the recorded measurement result by the UE is further described, which ensures that the UE can be constrained to indicate to the source cell and report the ANR Logs delay after the valid ANR measurement record is completed. Preferably, the reporting device of the neighboring cell relationship measurement result further includes: a processing unit 408, connected to the reporting unit 406, configured to set the locally saved enable identifier and the minimum number of entries N after the source cell successfully reports the recorded measurement result. Is empty. In the preferred embodiment, the step of reporting the measurement result after the UE reports the recorded result further ensures that the UE can be constrained to indicate to the source cell and report the ANR Logs delay after the valid ANR measurement record is completed. Embodiment 3 This embodiment provides a method for reporting a measurement result of a neighboring cell relationship, including the following steps: Initialization: Optionally, the capability of the UE to be forced to indicate and report ANR logs in the source cell is increased, so that the network can specify that the UE owns the After the capability, the UE will directly issue the ANR logs indication and report in the source cell. Step 1: Before the UE performs the ANRF measurement recording task Z, the source RNC optionally includes the parameters or cells shown in the following table in the A RF related control configuration parameters sent to the UE. Table 1

The UE receives and separately saves the above parameters into the local variables Enable_Source_ANR and Threshold_Source_ANR. The original state of these two variables is Null. Step 2: The UE in the PCH state measures the neighboring unknown cell in the source cell by using the DRX cycle defined in the PCH state. Once the UE measures that the unknown neighboring cell meets certain recording conditions, it logs it down. The UE in the Idle state measures the neighboring unknown cell in the source cell by using the DRX cycle defined in the Idle state. Once the UE measures that the unknown neighboring cell meets certain recording conditions, it logs it down. Note: At the same time, the UE is still doing the usual neighbor cell measurement in the neighbor list prepared for cell reselection. Therefore, it is possible that the UE has not re-selected from the source cell to the target cell, and the target cell becomes a new source cell. At this point, the Enable_Source_ANR and P Threshold Source ANR variable values remain until the RNC reconfigures them. Step 3: If the number of valid Log entries that the UE's Enable_Source_A R = TRUE and P has recorded is greater than or equal to Threshold_Source_ANR and any other possible factors that trigger the UE to report the neighbor relationship measurement results to the source cell have no effect. For the PCH state UE: Then immediately force the UE to have the periodic cell update timer timeout, and perform the source cell update procedure (Cell Update); for the Idle state UE: then immediately force the UE to perform the source cell RRC connection request procedure (RRC Connection) Request) o Similarly, a new trigger event localized by the UE may be defined, which is generated by the result of the AR Log behavior of the UE, and can trigger the UE to perform a cell update procedure or an RRC radio request procedure. Step 4: The UE reports the ANR logs record result in the source cell indication through the cell update procedure or the RRC radio request procedure. If the number of ANR Logs is large, it is not suitable for the public connection state Cell_FACH to report through the common channel. The RNC considers establishing a radio link, and allows the UE to enter the proprietary state Cell_DCH to report through the proprietary channel. Step 5: After successfully reporting the ANR Logging result, the UE clears the local variable Enable_Source_ANR = Null, Threshold Source AR = Null. Through the foregoing method for restricting the terminal to report the neighbor relationship to the source cell, the network can control the ANR measurement logging reporting behavior more effectively, but at the same time, the cost is increased by a certain signaling. It is worth noting that the network requires the UE to report the neighbor relationship to the source cell. It is cautious. Only when necessary, for example, if the UE is in the RNC region or the network discovers that the KPI index is poor, it needs to quickly make the corresponding neighbor. When the district relationship is adjusted. Embodiment 4, FIG. 5 is another flowchart of a method for reporting a neighbor cell relationship measurement result according to an embodiment of the present invention. The scenario in this embodiment is that an ANR-capable UE is in a Cell_DCH in a source cell (Source cell). The cell-specific channel) data transmission status, and then the data transmission ends into the Cell_PCH (Cell Paging Channel) state, and the source RNC where the source cell is located selects to perform the ANR task, and requests the ANR result to be reported in the source cell as soon as possible. Step 501: The source RNC sends the ANR-related control configuration parameter to the UE by using a physical channel reconfiguration message (Physical Channel Reconfiguration), including the two cells shown in Table 1 in Embodiment 3, and assigning the following values: Enabler for AR reporting in source cell = TRUE, Threshold NO. log entry for ANR reporting in source cell = 2. The UE saves them, so Enable_Source_A R = TRUE and Threshold Source AKR = 2. Step 502: The UE performs measurement on the neighboring cell in the neighboring cell list prepared for cell reselection while performing Cell A PNC state, and performs measurement of the unknown neighboring cell related to the ANR. As time passed, two unknown neighbor cells and corresponding Entry were found and recorded in the local ANR Log table. At this time, the UE does not find a very good target cell in the cell of its own neighbor list to perform cell reselection. Step 503: In this process, any other factors that trigger the UE to report the neighbor relationship measurement result to the source cell have no effect. Therefore, the UE immediately forces the UE to have a periodic cell update timer timeout, and performs a cell update process (Cell Update). Step 504: The UE reports the ANR logs record result in the source cell indication by using the cell update procedure. Since the number of logs is not very large, the UE reports only through the common channel in the Cell_FACH state. Step 505: After successfully reporting the AR Logging result, the UE clears the local variable Enable_Source_ANR = Null, Threshold Source AR = Null. Embodiment 5 FIG. 6 is still another flowchart of a method for reporting a neighbor cell relationship measurement result according to an embodiment of the present invention. The scenario in this embodiment is that an ANR-capable UE is in a Cell_DCH call state in a source cell. Then, the call ends to enter the Idle state, and the source RNC where the source cell is located selects to perform the ANR task, and requests the ANR result to be reported in the source cell as soon as possible. Step 601: The source RNC sends an RRC connection release message (RRC Connection Release), and sends the ANR-related control configuration parameter to the UE before the UE enters the Idle state, including two cells shown in Table 1 in Embodiment 3 and The assignments are as follows: Enabler for AKR reporting in source cell = TRUE, Threshold NO. log entry for ANR reporting in source cell = 4. The UE saves them, so Enable Source AR = TRUE and Threshold_Source_A R = 4. Step 602: The UE performs measurement on the neighboring cell in the neighbor list prepared for cell reselection while in the Idle state, and performs measurement of the unknown neighboring cell related to the ANR. As time passed, 4 unknown neighbor cells and corresponding Entry were found in the local ANR Log table. At this time, the UE does not find a very good target cell in the cell of its own neighbor list to perform cell reselection. Step 603: In this process, any other possible factors that trigger the UE to report the neighbor relationship measurement result to the source cell have no effect. The UE immediately forces the RRC Connection Request process (RRC Connection Request) of the source cell. Step 604: The UE reports the ANR logs record result in the source cell indication through the RRC connection request procedure. Due to the large number of logs, the RNC decides to establish a radio link, allowing the UE to enter the proprietary state Cell_DCH (cell-specific channel) to report through the proprietary channel. Step 605: After successfully reporting the AKR Logging result, the UE clears the local variable Enable_Source_ANR = Null, Threshold Source AKR = Null. From the above description, it can be seen that the present invention achieves the following technical effects: With the present invention, the terminal UE reports the measurement result to the source cell under the predetermined condition, and solves the problem that when the reselected target cell and the source cell are in different RNCs The problem of reporting ANR logs has a large delay, and then achieves the effect of being able to constrain the UE to perform a valid ANR measurement record, indicating to the source cell and reporting the ANR Logs delay, especially when the UE covers the source RNC. When the regional and target RNCs cover the boundary of the area, or when the UE reselects the cell to other systems.
