The priority of the above-identified Chinese patent application is incorporated herein by reference. Technical field

The present invention relates to the field of network communication technologies, and in particular, to a handover method, a handover apparatus, and a mobile terminal. Background of the invention

In the existing cellular mobile communication system, the handover is generally based on measurement, that is, the target cell is measured before the handover, and the handover can be triggered only when the signal quality of the target cell reaches a certain requirement.

In a CDMA (Code Division Multiple Access) system, the type of handover that is usually considered at the beginning is the same-frequency handover. That is, when the UE enters the service state, the same-frequency cell can be continuously measured. When the measurement result satisfies a certain condition. , trigger soft switching or hard switching. However, as the number of users continues to increase and the network continues to evolve, a single frequency point often fails to meet the capacity requirements, and new frequency points need to be superimposed. This introduces measurement and switching problems between different frequency points. In addition, considering the use of existing GSM networks, it is also necessary to consider the measurement and switching problems of System II).

The basis of the handover measurement is to determine the target cell that needs to be measured, that is, to determine the neighboring cell. There are usually two ways to determine the target cell: 1. The system broadcasts or sends a list of measurement neighbors to the UE. 2. The UE searches for all detectable cells.

The execution of the handover must be controlled by the network. The network needs the necessary information to switch the target cell in order to prepare for the handover. Therefore, in practical applications, the method 1 is mostly used to determine the target cell. However, the biggest disadvantage of the method 1 is that it has a large degree of reliance on the network planning, that is, if the neighboring area of the neighboring area is measured, the UE may not be able to correctly select the target cell to be switched, which may result in the loss. words. Summary of the invention

The embodiment of the present invention provides a handover method, a handover apparatus, and a mobile terminal. By causing the mobile terminal to detect and report the missing neighboring cell information, the workload of the network optimization is reduced, and the leakage caused by the neighboring zone is effectively avoided. Word phenomenon.

If the mobile terminal can not only perform neighbor cell measurement according to the neighbor cell information configured in the measurement neighbor list, but also can The neighboring area measurement is performed on the missing neighboring area except the neighboring area configured in the neighboring cell list, and the network side can determine the target cell according to the more comprehensive neighboring area information, thereby avoiding the neighbors configured in the measured neighboring area list. When the area does not meet the switching conditions, the user dropped calls, which greatly reduces the dropped call rate, thereby reducing the network optimization workload and improving the efficiency of network optimization.

The missing matching neighboring area in the embodiment of the present invention may be: the same frequency leakage matching neighboring area, or may be: an inter-frequency leakage matching neighboring area, or may be a mismatched adjacent area of the different system. The technical solutions provided by the embodiments of the present invention are described in detail below by taking the inter-frequency leakage neighboring zone and the different system leakage matching neighboring zone as an example.

First, the network side of the embodiment of the present invention needs to send the indication information for detecting the missing neighboring cell to the UE, and the network side can satisfy the condition of the inter-frequency/different system measurement, and the inter-frequency/differential system mismatch configured on the network side. When the neighboring area detection function is enabled, the indication information for detecting the missing neighboring area is sent to the UE. The network side sends the indication information of the missing neighboring cell to the UE to enable the UE to detect the missing neighboring cell, that is, the network side indicates the UE to report the mismatched inter-frequency cell/different system by using the indication information of the missing neighboring cell. Cell information.

For the inter-frequency mismatched neighboring cell, the indication information of the detecting the missing neighboring cell may be: one or two of the frequency range of the neighboring cell and the reporting condition of the missing neighboring cell that need to be detected. When the indication information for detecting the missing neighboring cell includes only one of the frequency binning range of the missing matching neighboring cell and the missing matching neighboring cell reporting condition, the other may be set by the UE itself. '

For the mismatched neighboring area of the different system, the indication information for detecting the missing neighboring area may be: a BSIC (Basic Transmitting Station Identity Code) frequency range and a missing neighboring area of the missing matching neighboring area to be detected. One or two of the escalation conditions. Similarly, when the indication information for detecting the missing neighboring cell includes only one of the BSIC frequency range and the missing neighboring cell reporting condition of the missing neighboring cell to be detected, the other may be set by the UE itself.

The opening and closing of the above-mentioned inter-frequency leakage matching neighbor detection function is controlled by the network side.

The reporting condition of the inter-frequency mismatch neighboring cell may be a CPICH Ec/No (signal-to-noise ratio of the pilot channel) threshold or a CPICH RSCP (received signal code power of the pilot channel) threshold, and the threshold may be an absolute threshold. It can also be a relative threshold, such as a threshold relative to the current active set quality. The reporting condition of the mismatched neighboring cell of the different system may be the absolute threshold of the RSSI (received signal strength indication) measurement value and whether the BSIC is decoded.

The network side can send the indication information of the detection of the missing neighboring cell to the UE through the current measurement control process, that is, the network side can configure the indication information of the detection of the missing neighboring area in the measurement control information and send it to the UE, and the leakage is performed. The neighboring cell should be a cell that does not include the measurement neighboring cell line that is sent by the network side.

When receiving the indication information of the missing neighboring area sent by the network, the UE performs the leakage of the required frequency on the network side. With neighboring area detection function. When the network side sends the indication information of the missing neighboring area through the existing measurement control process, the UE needs to perform the inter-frequency/different system measurement required by the network side, and simultaneously perform the missing-match neighboring area detection of the frequency point required by the network side. Features. The network side transmits the detection of the mismatched neighboring area indication information by using the existing measurement control process, so that the technical solution of the embodiment of the present invention is easy to implement. .

If the detected set cell of the UE meets the reporting condition of the missing neighboring cell, the UE reports the detected set cell that meets the condition to the network side by using the measurement report. The measurement report reported by the UE needs to include the measured value of the missing neighboring cell. For the GSM cell, if the network side requires BSIC decoding, the measurement report needs to include the decoded BSIC information of the missing neighboring cell. The UE can easily implement the technical solution of the embodiment of the present invention by using the existing measurement report to transmit the measured value of the missing matching neighboring area that satisfies the reporting condition.

After receiving the measurement report reported by the UE, the network side determines whether the measurement report includes the missing neighboring area of the required frequency point. If the measurement report does not include the information of the missing neighboring area, the network side follows the current normal The inter-frequency handover algorithm performs a handover decision, that is, when the inter-frequency/different system neighboring cell in the measurement report satisfies the handover condition, the handover process is initiated; if the measurement report includes the information of the mismatched neighboring cell, the measurement is preferentially directed to the neighbor list. The inter-frequency/different system cell configured in the middle of the handover, that is, if the inter-frequency/different system neighboring cell in the neighboring cell list satisfies the handover condition, the inter-frequency/differential from the measurement neighbor list that satisfies the handover condition The target cell is selected in the neighboring system, and then the handover process is performed. At this time, the missing neighboring cell reported by the UE can be recorded only as a voice system. If the measurement report includes the information of the missing neighboring cell, and only the missing neighboring cell meets the switching condition, and the missing neighboring cell can be uniquely determined, the network side determines the missing neighboring cell as the target cell, and then, to the missing cell The neighboring area initiates an inter-frequency handover process. The network side switches the neighboring area configured in the neighboring cell list according to the priority, and the impact of the application of the embodiment of the present invention on the existing network planning is avoided.

The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The flow of the handover method of the embodiment of the present invention is as shown in FIG. In FIG. 1, in step 1-1, the UE reports a measurement report to the R C, and the measurement report triggers the inter-frequency/differential system measurement. The UE may report the measurement report to the RNC when the CPICH Ec/No of the current optimal cell is lower than a certain threshold; the UE may also report the measurement report to the RNC when the uplink transmit power reaches the maximum value; the UE may also have a downlink BLER greater than When the threshold is preset, the measurement report is reported to the RNC. The embodiment of the present invention does not limit the specific implementation method for the UE to report the measurement report to the RNC. .

To step 1-2, the RNC determines the indication information for detecting the missing neighboring cell, that is, the RNC performs the configuration of the missing neighboring cell parameter. The parameters of the missing neighboring area include: a frequency range of the missing matching neighboring area or a BSIC frequency range, and a reporting condition of the missing matching neighboring area. Go to step 1-3. The RNC sends the missing neighboring cell parameters to the UE through the measurement control process.

To step 1-4, the UE performs a neighboring area measurement and evaluation process according to the received neighbor list and the indication information of the missing neighboring cell. '

Go to Step 1-5. The UE reports the neighboring area measurement and evaluation results to the KNC through the measurement report.

To the 1-6, the NC performs a missed-to-neighbor determination and handover evaluation process according to the measurement report reported by the UE, and determines the target cell by using a method of preferentially switching to the cell in the neighboring cell list, as described in the foregoing embodiment. .

After the target cell is determined, the RNC sends a handover command to the UE.

Go to step 1-8. After receiving the handover command, the UE performs a handover operation and returns a handover completion response message to the RNC.

Step 1-2 in Figure 1 above, the specific implementation process of the RNC performing the configuration of the missing neighboring zone parameter is shown in Figure 2. In FIG. 2, after receiving the measurement report of the UE in step 2-1, the RNC starts the parameter configuration process of the missing neighboring cell. Go to step 2-2. The RNC determines whether the inter-frequency/differential system mismatch neighbor detection function is enabled. If the inter-frequency/extra system mismatch neighbor detection function is not enabled, the RNC sets the measurement control information according to the existing method. Step 2-3: The RNC starts the measurement control process, and sends measurement control information to the UE. '

In step 2-2, if the inter-frequency/extra-system mismatch neighbor detection function is enabled, then to step 2-4, the RNC determines the frequency range or BSIC frequency range of the missing neighbor region to be detected, and performs measurement control. Set the frequency range or BSIC frequency range of the missing neighboring area to be detected in the information.

Go to step 2-5, the RNC determines the reporting conditions of the neighboring zone in the neighboring zone and the neighboring cell list, and sets the reporting conditions of each neighboring cell in the detection set, and sets the reporting of the missing neighboring cell in the measurement control information. condition.

Go to step 2-3. The RNC starts the measurement control process and sends measurement control information to the UE.

Steps 1-6 in Figure 1 above, the specific implementation process of the RNC to perform the missed neighbor decision and handover evaluation process according to the measurement report reported by the UE is as shown in FIG.

In Figure 3, in step 3-1, the RNC receives the measurement report reported by the UC and starts processing the measurement report. Go to step 3-2. The RC determines whether there is missing neighboring cell information in the measurement report. If there is no missing neighboring cell information in the measurement report, go to step 3-6. The RNC continues to determine the measurement neighbor list configuration in the measurement report. Whether the inter-frequency/different system neighboring area satisfies the handover condition. If the configuration inter-frequency/different system neighboring cell in the neighboring cell list satisfies the handover condition, go to step 3-7, and configure the difference from the measurement neighboring cell list that satisfies the handover condition. The target cell is selected in the neighboring area of the frequency/different system, and then handover processing is performed. Go to step 3-8, and the process of evading the neighboring zone decision and handover evaluation ends.

In step 3-6, if the configuration inter-frequency/different system neighboring cell in the neighboring cell list does not satisfy the switching condition, go to step 3-1. When receiving the measurement report reported by the UC, the RC starts to process the measurement report.

In step 3-2, if there is missing neighboring cell information in the measurement report, the RNC will use the missing neighboring cell reported by the UE as the traffic statistics record in step 3-3. Go to step 3-4 and continue to determine whether the inter-frequency/different system neighboring zone configured in the neighboring cell list meets the switching condition. If the inter-frequency/different system neighboring zone configured in the neighboring cell list meets the switching condition, go to step 3. -7. The RC selects a target cell from the inter-frequency/different system neighboring zone configured in the measurement neighboring cell list that satisfies the handover condition, and then performs handover processing. Go to step 3-8, and the process of evading the neighboring zone decision and handover evaluation ends.

In step 3-4, if the inter-frequency/different system neighboring cell configured in the neighboring cell list does not satisfy the handover condition, the RNC determines whether the mismatched neighboring cell reported by the UE meets the handover condition and the mismatched neighbor Whether the area can be uniquely determined. If the missing neighboring area reported by the UE meets the handover condition and the missing neighboring area can be uniquely determined, then to step 3-7, the RC is determined as the target cell from the missing matching neighboring area that satisfies the handover condition. Then, an inter-frequency handover procedure is initiated to the missing neighboring cell. Go to step 3-8, and the process of evading the neighboring zone decision and handover evaluation ends.

In step 3-5, if the missing neighboring cell reported by the UE does not meet the handover condition, or the missing neighboring cell cannot be uniquely determined, the RNC starts the measurement report when receiving the measurement report reported by the UC in step 3-1. Process it.
