Description

Method and device for minimizing road test based on heterogeneous network

The present invention relates to the field of network communication technologies, and in particular, to a method and a device for minimizing road test measurement based on a heterogeneous network. Background technique

In the current communication system, the planning and adjustment of the network system needs to be verified by DT (Drive Test) to ensure the network optimization is qualified. DT is a method for testing downlink signals of wireless networks for network quality assessment and wireless network optimization. It generally includes two methods: manual road test and MDT (Minimization of Drive-Tests). Because manual road test has the disadvantages of high cost and limited road test route, MDT is the most commonly used technical means in road test.

The MDT is a process of modifying the signaling or OAM (Operation Administration and Maintenance, OAM can also be referred to as the background operation and maintenance management platform), so that the operator can pass the UE (User Equipment, which has already resided in the network). User equipment) collects wireless data. During the MDT measurement process, the UE performs the MDT measurement according to the MDT parameter configuration information contained in the activation message sent by the OAM to the RNC when performing the MDT measurement.

In order to better describe the technical solution of the present invention, the applicant first introduces the background art and the inventive principle of the present invention as follows.

In a mobile communication network, a typical heterogeneous network includes: a macro base station (Macro) and a micro base station (Pico), and further may include a home base station (Femto) and a relay base station (Relay). The Macro cell under the macro base station is used to provide wide area coverage; the Pico cell under the micro base station is used to increase the capacity of the hotspot service area, and the load of the Macro cell is balanced; and the Femto cell under the home base station is used to provide more for the individual home users. Good quality of service; Relay cells under the relay base station are used to extend the coverage of the edge of the Macro cell, or deployed at a location where it is not convenient to deploy a wired backhaul.

The inventors found in the process of implementing the present invention that the existing MDT measurement method is not suitable

Hetnet heterogeneous network. The applicant below briefly introduces the existing MDT measurement method.

Step 1001: The core network or the OAM sends an activation message to the radio network controller RNC, where the activation message includes the MDT parameter configuration information.

It should be noted that the MDT parameter configuration information included in the activation message in the prior art is used to specify a large range of measurement areas. For example, the A area includes a Pico cell and a Femto cell. At this time, the MDT parameter configuration information specifies that the MDT measurement is performed on the A area. Then, the MDT measurement is performed on the Pico cell and the Femto cell in the A area.

Of course, the RNC here can also be replaced by an eNB (evolved Node B). Step 1002: The RNC receives the activation message, obtains the MDT parameter configuration information in the activation message, and generates a measurement request message. The measurement request message includes MDT parameter configuration information.

Step 1003: The RNC sends the generated measurement request message to the UE.

Step 1004: After receiving the measurement request message, the UE reads the MDT parameter configuration information in the measurement request message, and performs MDT measurement on the Pico cell and the Femto 'J, the area in the A area.

In the prior art, the MDT parameter configuration information can only be used to specify a large range of measurement areas, and different types of cells included in the measurement area cannot be distinguished. Therefore, when there are different types of cells in the measurement area, and the network side only needs to perform MDT measurement on a certain type of cell in the measurement area, such as a Pico cell in the A area, to obtain MDT measurement data of the Pico cell, the UE needs The MDT measurement is performed on the Pico cell and the Femto cell in the A area, and the measurement data is reported to the network side, and the network side further extracts the MDT measurement data measured for the Pico cell. Therefore, existing In the above measurement method in the technology, when the network side only wants to obtain the MDT measurement data of a certain type of cell in the measurement area, the UE needs to perform MDT measurement on all types of cells in the measurement area, and all the MDT measurements from the network side are measured. The MDT measurement data of the certain type of cell is further extracted in the data. Therefore, the UE measures a large amount, increases the measurement work of the UE, and wastes measurement resources.

Based on the above, the present invention provides a measurement method and a device for minimizing a drive test based on a heterogeneous network, which are used to solve the problem that the UE needs to waste measurement resources caused by MDT measurement in all cells in the measurement area, and the problem of the UE measurement work is aggravated. .

BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without the creative work are all within the scope of the present invention.

Referring to Figure 1, there is shown a flow chart of a heterogeneous network based minimization drive measurement method provided by the present invention. The method can include:

Step 101: The UE receives a measurement request message sent by the network side. The measurement request message includes MDT parameter configuration information. The MDT parameter configuration information is used to indicate that the UE learns a specific type of target measurement cell.

In this embodiment, the MDT parameter configuration information includes at least one of cell frequency layer information and cell identification information. The cell frequency layer information and the cell identity information may be collectively referred to as cell type information. The type of the cell can be determined based on the cell frequency layer information and/or the cell identification information.

Specifically, the cell identity information may further include cell physical identity information and cell type identity information.

Step 102: The UE determines a specific type of target measurement cell according to the MDT parameter configuration information. In this embodiment, after receiving the measurement request message sent by the network side, and acquiring the MDT parameter configuration information included in the network, the UE may first determine a specific type of target measurement cell according to the MDT parameter configuration information.

Step 103: The UE performs MDT measurement on a specific type of target measurement cell to obtain MDT measurement data.

After determining a specific type of target measurement cell in the measurement area, MDT measurement is performed only on a specific type of target measurement cell in the measurement area, and MDT measurement data is acquired. The specific type of target measurement cell is a cell with certain characteristic attributes in the measurement area. In this embodiment, after receiving the measurement request message sent by the network side, the UE does not perform MDT measurement for all cells in the measurement area, but first determines a specific type in the measurement area according to the MDT parameter configuration information. The cell is a target measurement cell, and MDT measurement is performed only for a specific type of target measurement cell.

The foregoing example is taken as an example. For example, the A area is a measurement area, which includes two specific cells, a Pico 'J, a zone, and a Femto cell. The frequency corresponding to the Pico cell is fl, and the frequency corresponding to the Femto cell is f2. At this time, the MDT parameter configuration information is the A region fl frequency, and then the specific type of target measurement cell is the cell with the frequency point fl in the A region. The UE determines, according to the information of the "A area fl frequency point", that the Pico cell with the frequency point fl in the A region is the target measurement cell, and performs MDT measurement on the Pico cell.

In the following, the applicant will take different MDT parameter configuration information as an example for detailed description.

In this embodiment, the UE may determine a specific type of target measurement cell according to the cell frequency layer information and/or the cell identification information.

Case 1, in practical applications, different types of cells use different frequency points or frequency bands. For example, the Pico cell uses the frequency fl, the Femto cell uses the frequency f2, the Macro cell uses the frequency point β, and the micro cell uses the frequency point f4. Or the Pico cell uses the frequency band fl~f2, the Femto cell uses the frequency band ί2~β, the Macro cell uses the frequency band β~f4, and the micro cell uses the frequency band f4~f5.

At this time, when the MDT parameter configuration information is cell frequency layer information for indicating a specific frequency point or a specific frequency band, the UE determines that the specific frequency point or the cell in the specific frequency band is the target measurement cell.

For example, the MDT parameter configuration information is specifically a frequency point, then the specific frequency point is f2, that is, the MDT parameter configuration information indicates a cell with a specific frequency point. If the current UE resides in a Femto cell with a frequency of 1, the MDT measurement is performed directly on the Femto cell. If the current UE camps on another frequency point cell, such as a Macro cell with a frequency point of β, after receiving the measurement request message, the UE searches for the Femto cell with the frequency point according to the MDT parameter configuration information, and after finding the Femto cell, from the Macro The cell jumps to the Femto cell and performs MDT measurements on the Femto cell.

Here, if the UE cannot find the Femto cell with the frequency point f2, the UE may be set to periodically search for the frequency point f2. For example, after the frequency point f2 cannot be found for the first time, the preset time is set, for example, 2s again initiates the action of finding the frequency point. You can also set the search action for a preset time, or reach the preset. After the threshold value of the number of times is no longer found, the search action can be set until the frequency point β is found. Similarly, when the MDT parameter configuration information is specifically a certain frequency band, the MDT parameter configuration information indicates that the cell in the specific frequency band is the target measurement cell. The implementation process is similar to the case where the MDT parameter configuration information is a certain frequency point, and the inventors will not repeat them.

Case 2: In order to distinguish different types of cells, each cell has a physical identifier for distinguishing other cells. Generally, the physical identity may include a cell ID (identity, identification number).

In this embodiment, when the MDT parameter configuration information includes the cell identification information for indicating a specific type, the specific type of the cell is determined as the target measurement cell.

In practical applications, a plurality of different types of cells are included in the measurement area covered by the network. Each type of cell broadcasts system messages. The system message may include a physical identifier indicating a specific cell type, and may also include information of a specific cell type.

Specifically, when the system message broadcasted by the cell includes the physical identifier of the specific cell type, the UE distinguishes different types of cells according to the received physical identifier. When the system message broadcasted by the cell includes the information of the specific cell type, the UE directly learns the type of the cell by reading the information of the cell type.

In this embodiment, if the network side needs to perform MDT measurement on the type-a cell, the UE obtains the MDT parameter configuration information included in the measurement request message after receiving the measurement request message sent by the network side, and determines the specific type according to the MDT parameter configuration information. The cell is measured for the cell of a.

Specifically, the MDT parameter configuration information is specifically a type, and then the specific type is a, that is, the MDT parameter configuration information indicates a cell of a specific type a. After receiving the measurement request message sent by the network side, the UE acquires the MDT parameter configuration information included in the measurement request message. At the same time, the UE receives the system message broadcasted by the cell, and determines, according to the system message, that the cell of the specific type a is the target measurement cell. If the current UE camps on the a type cell, the UE directly performs MDT measurement on the type a cell. If the current UE camps on another type of cell, such as a b-type cell, after receiving the measurement request message, the UE searches for the type-a cell according to the MDT parameter configuration information, and after finding the type-a cell, jumps from the b-type cell to the A type cell, performing MDT measurement on a type cell.

In the third example, the MDT parameter configuration information may also include cell frequency layer information for indicating a specific frequency point or a specific frequency band and indicating cell identification information of a specific type, and the information included in the MDT parameter configuration information is used for indication. Cell frequency layer information of a specific frequency point or a specific frequency band and cell identification information for indicating a specific type, determining the specific frequency point or a specific type in a specific frequency band The cell is a target measurement cell.

In this embodiment, the MDT parameter configuration information is specifically the feature combination information of "specific frequency point or specific frequency band + specific type". For example, the MDT parameter configuration information is specifically “band f2~fi+a type”, then the UE determines that the cell in the specific frequency band f2~β is in the specific frequency band f2~β according to the MDT parameter configuration information, and the cell of the specific type a is the target measurement cell. Here, the process of determining the cell in the frequency band β~β and determining the cell of the specific type a is the target measurement cell is the same as the previous example. The implementation of the present example can be understood as a combination of the foregoing two methods. The specific implementation process can be referred to the foregoing, and the inventors will not repeat them here.

Based on the foregoing embodiment, the MDT parameter configuration information may further include measurement area information. At this time, the UE determines a specific type of target measurement cell according to the cell frequency layer information and/or the cell identification information and the measurement area information.

Case 4: In a large measurement area, dividing a different cell by a region range, the larger measurement area can be divided into several smaller measurement areas, so as to increase the target MTD measurement of the UE to be measured. .

For a more in-depth understanding, reference is made to Figure 2 which shows a partial schematic view of the measurement area of the present invention.

In a practical application, a base station may serve one or more cells, and the measurement area may be divided according to the service area of the base station, as shown in FIG. 2, for example, the first base station serves the first Femto cell, the second Femto cell, The first Pico cell and the second Pico cell. The second base station serves the third Femto cell, the fourth Femto cell, the fifth Femto cell, and the third Pico cell. At this time, all cells served by the first base station are collectively referred to as a first cell, and all cells served by the second base station are collectively referred to as a second cell.

When the network side needs to perform MDT measurement on the first cell served by the first base station, the MDT parameter configuration information in the measurement request message sent by the network side to the UE indicates that the UE measures the first cell. After receiving the measurement request message, the UE acquires the MDT parameter configuration information, and performs MDT measurement on the first cell according to the MDT parameter configuration information. The MDT parameter configuration information used by the UE to measure the first cell may be a list, and the range information about the first cell is recorded in the list.

In this embodiment, the MDT parameter configuration information may include measurement area information for indicating a measurement area and cell frequency layer information for indicating a specific frequency point or a specific frequency band. Still following the above examples Continued explanation. If the MDT parameter configuration information includes the measurement area information of the first cell and the cell frequency layer information of the frequency point f2, that is, the MDT parameter configuration information is the feature combination information of the “first cell+frequency point f2”. Then, the specific type of target measurement cell at this time is the cell in the first cell and the frequency point is.

After receiving the measurement request message, the UE obtains the MDT parameter configuration information, and determines, according to the measurement area information of the first cell, that the first base station served in the measurement area includes the first Femto cell, the second Femto cell, the first Pico cell, and the second The first cell of the Pico cell. At the same time, the UE determines the Femto cell with the frequency point f2 according to the cell frequency layer information of the frequency point β. At this time, in combination with the first cell and the Femto cell determined by the UE, the target measurement cell of the "Femto cell in the first" zone conforming to the "first cell + frequency point" feature is determined.

In the fifth example, the MDT parameter configuration information may further include measurement area information for indicating the measurement area and cell identification information for indicating a specific type.

For example, the MDT parameter configuration information includes the measurement area information of the first cell and the area identification information of the a type, that is, the MDT parameter configuration information is the feature combination information of the “first cell + a type”. Then, the specific type of target measurement cell at this time is the cell of type a in the first cell.

Similarly, after receiving the measurement request message, the UE acquires the MDT parameter configuration information, and determines, according to the measurement area information of the first cell, that the first base station serving the first base station, the second Femto cell, and the first Pico cell in the measurement area. And the first 'zone of the second Pico cell. At the same time, the UE determines the cell of type a according to the cell identification information of type a. At this time, in combination with the first cell and the a type cell determined by the UE, the target measurement cell of the "a type cell in the first cell" that conforms to the "first cell + a type" feature is determined.

In the sixth example, the MDT parameter configuration information may further include measurement area information for indicating the measurement area, cell frequency layer information for indicating a specific frequency point or a specific frequency band, and cell identification information for indicating a specific type.

For example, the MDT parameter configuration information includes measurement area information of the first cell, cell frequency layer information of the frequency point f2, and cell identification information of type a, that is, the MDT parameter configuration information is “first cell + frequency point β+a type”. Feature combination information. Then, the specific type of target measurement cell at this time is the cell of type a in the first cell, which uses the frequency point.

Similarly, after receiving the measurement request message, the UE acquires the MDT parameter configuration information, according to the first The measurement area information of the cell determines a first 'area that includes the first Femto cell, the second Femto cell, the first Pico cell, and the second Pico cell served by the first base station in the measurement area. At the same time, the UE determines the Femto cell with the frequency point f2 according to the cell frequency layer information of the frequency point. And, the UE determines the cell of type a according to the cell identification information of type a. At this time, in combination with the first cell, the Femto cell, and the a-type cell determined by the UE, the "a type cell in the Femto cell in the first cell" that meets the "first cell + frequency point f2+a type" feature is determined. The target measures the cell.

It should be noted that, when the MDT parameter configuration information is the feature combination information, in determining a specific type of target measurement cell, determining a cell range in the measurement area, determining a cell using a certain frequency point or frequency band, and determining a certain The implementation process and sequence of a type of cell are not limited. For example, the process of the UE determining that the Femto cell in the first cell is the target measurement cell may be: the UE first determines the first cell according to the measurement area information, and then determines the Femto cell in the first cell according to the cell frequency layer information. The Femto cell determined at this time is the target measurement cell; the UE may first determine all the Femto cells according to the cell frequency layer information, and then determine the Femto cell in the first cell according to the measurement area information, and determine at this time. The Femto cell is the target measurement cell; the UE may determine the process of the first cell according to the measurement area information and the process of determining the Femto cell according to the cell frequency layer information, and combine the obtained results to determine the target. Measuring the cell. Other implementations of the invention will not be enumerated by the inventors. Any implementation that achieves the objectives of the invention is within the scope of the invention.

Applying the above technical solution of the present invention, in the measurement method for minimizing the drive test based on the heterogeneous network, after receiving the measurement request message sent by the network side, the user equipment firstly configures according to the MDT parameter in the measurement request message. Information, determining a specific type of target measurement cell within the measurement area; and then performing MDT measurement for a specific type of target measurement cell to obtain MDT measurement data. Therefore, the present invention does not need to perform MDT measurement on all types of cells in the measurement area, and can directly measure the specific type of cells in the measurement area that need to perform MDT measurement, thereby improving the efficiency of measuring resources and avoiding waste of measurement resources, and The measurement work of the UE is reduced.

In addition, based on the description of the measurement method of the minimization of the drive test based on the heterogeneous network protection, the embodiment of the present invention further provides a user equipment. Referring to FIG. 7, the present invention is provided. A schematic structural diagram of a user equipment includes: a receiving module 701, a determining module 702, an MDT measuring module 703, and an MDT measurement data acquiring module 704. among them,

The receiving module 701 is configured to receive a measurement request message sent by the network side, where the measurement request message includes minimizing the drive test MDT parameter configuration information. The MDT parameter configuration information is used to indicate that the user equipment learns a specific type of target measurement cell;

In this embodiment, the MDT parameter configuration information includes at least one of cell frequency layer information and cell identity information. The cell frequency layer information and the cell identity information may be collectively referred to as cell type information. Based on the cell frequency layer information and/or the cell identity information, the type of the cell can be determined. Specifically, the cell identity information may further include cell physical identifier information and cell type identifier information.

The determining module 702 is configured to determine a specific type of target measurement cell according to the MDT parameter configuration information.

In this embodiment, after receiving the measurement request message sent by the network side, the receiving module 701 obtains the MDT parameter configuration information included therein, and determines, according to the MDT parameter configuration information, the specific type of target measurement cell by the determining module 702. The specific type of target measurement cell is a cell with certain characteristic attributes in the measurement area.

The MDT measurement module 703 is configured to perform MDT measurement on a specific type of target measurement cell.

The MDT measurement data acquisition module 704 is configured to acquire MDT measurement data.

In this embodiment, after the determining module 702 determines a specific type of target measurement cell in the measurement area, the MDT measurement module 703 performs MDT measurement only on a specific type of target measurement cell in the measurement area, and passes the MDT measurement data acquisition module 704. Obtain MDT measurement data.

In the present invention, after receiving the measurement request message sent by the network side, the receiving module 701 determines, according to the MDT parameter configuration information in the measurement request message, the determining module 702 determines that a specific type of cell in the measurement area is the target measurement cell. . The present invention does not perform MDT measurement for all cells in the measurement area, but determines, according to the MDT parameter configuration information, the determining module 702 determines that a certain type of cell in the measurement area is the target measurement cell, and only measures the cell of the specific type. Perform MDT measurements.

For example, the Α area is a measurement area, which includes two specific cells, a Pico cell and a Femto cell. The frequency corresponding to the Pico cell is fl, and the frequency corresponding to the Femto cell is f2. At this time, the MDT parameter configuration information is the A region fl frequency, and then the specific type of target measurement cell is the cell with the frequency point fl in the A region. The determining module 502 determines, according to the information of the "A-area fl-frequency point", that the Pico cell with the frequency point fl in the A region is the target measurement cell, and performs MDT measurement on the Pico cell.

In the following, the applicant will take different MDT parameter configuration information as an example to describe in detail how the module 502 determines a specific type of target measurement cell.

Case 1, in practical applications, different types of cells use different frequency points or frequency bands. For example: Pico cell uses frequency point fl, Femto cell uses frequency point Ώ, Macro cell uses frequency point β, micro small The zone uses the frequency point f4. Or the Pico cell uses the frequency band fl~f2, the Femto cell uses the frequency band ί2~β, the Macro cell uses the frequency band β~f4, and the micro cell uses the frequency band f4~f5.

At this time, when the MDT parameter configuration information is used to indicate the cell frequency layer information of the specific frequency point or the specific frequency band, the determining module 702 is specifically configured to: determine that the specific frequency point or the cell in the specific frequency band is the target measurement cell.

For example, the MDT parameter configuration information is specifically a frequency point, then the specific frequency point is f2, that is, the MDT parameter configuration information indicates a cell with a specific frequency point. If the current UE resides in a Femto cell with a frequency of 1, the MDT measurement is performed directly on the Femto cell. If the current UE camps on another frequency point cell, such as a Macro cell with a frequency point of β, after the receiving module 701 receives the measurement request message, the determining module 702 searches for the Femto cell with the frequency point according to the MDT parameter configuration information. After the Femto cell, it is determined that the Femto cell is the target measurement cell, and the MDT measurement is performed on the Femto cell.

Here, if the determining module 702 cannot find the Femto cell with the frequency point f2, the determining module 702 can periodically set the frequency point f2. For example, after the frequency point is not found for the first time, the interval preset time, such as 2s, initiates the action of finding the frequency point again. It is also possible to set the search action for a preset time, or to reach the threshold value of the preset number of times, and then no longer search, or set the search action until the frequency is found.

Similarly, when the MDT parameter configuration information is specifically a certain frequency band, the MDT parameter configuration information indicates that the cell in the specific frequency band is the target measurement cell. The implementation process is similar to the case where the MDT parameter configuration information is a certain frequency point, and the inventors will not repeat them.

In this embodiment, when the MDT parameter configuration information includes the cell identification information for indicating a specific type, the determining module 702 is specifically configured to: determine that the specific type of cell is the target measurement cell.

Specifically, when the system message broadcasted by the cell includes the physical identifier of the specific cell type, the UE distinguishes different types of cells according to the received physical identifier. When the system message broadcasted by the cell includes specific When the information of the cell type is read, the UE directly learns the type of the cell by reading the information of the cell type.

Specifically, the MDT parameter configuration information is specifically a type, and then the specific type is a, that is, the MDT parameter configuration information indicates a cell of a specific type a. After receiving the measurement request message sent by the network side, the receiving module 701 acquires the MDT parameter configuration information included in the measurement request message. At the same time, the determining module 702 receives the system message broadcasted by the cell, and determines, according to the system message, that the cell of the specific type a is the target measurement cell. If the current UE camps on the a type cell, the UE directly performs MDT measurement on the type a cell. If the current UE camps on another type of cell, such as a b-type cell, after the receiving module 701 receives the measurement request message, the determining module 702 searches for the type-a cell according to the MDT parameter configuration information, and after finding the type-a cell, determining The a type cell is a target measurement cell, and performs MDT measurement on the type a cell.

In the third example, the MDT parameter configuration information may also include cell frequency layer information for indicating a specific frequency point or a specific frequency band and the cell identification information for indicating a specific type. The determining module 702 is specifically configured to: configure according to the MDT parameter. The cell frequency layer information for indicating a specific frequency point or a specific frequency band and the cell identification information for indicating a specific type included in the information, determining that the specific frequency point or a specific type of cell in the specific frequency band is the target measurement cell.

In this embodiment, the MDT parameter configuration information is specifically the feature combination information of "specific frequency point or specific frequency band + specific type". For example, the MDT parameter configuration information is specifically "band f2~fi+a type", then the determining module 702 determines that the cell in the specific frequency band f2~β is in the specific frequency band f2~β according to the MDT parameter configuration information, and the cell of the specific type a is the target measurement cell. Here, the process of the determining module 702 determining the cell in the frequency band Ώ~β and determining the cell of the specific type a type as the target measurement cell is the same as the previous example. The implementation of the present example can be understood as a combination of the foregoing two methods. The specific implementation process can be referred to the foregoing, and the inventors will not repeat them here.

For a more in-depth understanding, reference may be made to Figure 2, which shows a portion of the measurement area of the present invention. Schematic.

When the network side needs to perform MDT measurement on the first cell served by the first base station, the MDT parameter configuration information in the measurement request message sent by the network side to the UE indicates that the UE measures the first cell. After receiving the measurement request message, the receiving module 701 in the UE obtains the MDT parameter configuration information, and the determining module 702 determines that the first cell is the target measurement cell according to the MDT parameter configuration information, and the MDT measurement module 703 performs the MDT measurement on the first 'area. The MDT parameter configuration information used to indicate that the UE measures the first 'area may be a list, and the range information about the first cell is recorded in the list.

In this embodiment, the MDT parameter configuration information may include measurement area information for indicating a measurement area and cell frequency layer information for indicating a specific frequency point or a specific frequency band. The description continues with the above examples. If the MDT parameter configuration information includes the measurement area information of the first cell and the cell frequency layer information of the frequency point f2, that is, the MDT parameter configuration information is the feature combination information of the “first cell + frequency point f2”. Then, the specific type of target measurement cell at this time is the cell in the first cell and the frequency point is. The determining module 702 is specifically configured to: determine that the cell in the measurement area, that is, the cell in the first cell, the specific frequency point f2 is the target measurement cell.

After receiving the measurement request message, the receiving module 701 obtains the MDT parameter configuration information, and the determining module 702 determines, according to the measurement area information of the first cell, that the first base station served in the measurement area includes the first Femto cell, the second Femto cell, and the first The first 'J, zone of the Pico cell and the second Pico cell. At the same time, the determining module 702 determines the Femto cell with the frequency point according to the cell frequency layer information of the frequency point f2. At this time, in combination with the determined first cell and the Femto cell, the target measurement cell of the "Femto cell in the first cell" that conforms to the "first cell + frequency point f2" feature is determined.

In the fifth example, the MDT parameter configuration information may further include measurement area information for indicating the measurement area and cell identification information for indicating a specific type. At this time, the determining module 702 is specifically configured to: determine that a specific type of cell in the measurement area is a target measurement cell. For example, the MDT parameter configuration information includes the measurement area information of the first cell and the cell identification information of the a type, that is, the MDT parameter configuration information is the feature combination information of the “first cell+a type”. Then, the specific type of target measurement cell at this time is the cell of type a in the first cell. The determining module 702 is configured to determine that the cell of type a is the target measurement cell in the measurement area, that is, in the first cell.

Similarly, after receiving the measurement request message, the receiving module 701 obtains the MDT parameter configuration information, and the determining module 702 determines, according to the measurement area information of the first cell, that the first base station service includes the first Femto cell and the second Femto cell in the measurement area. And a first cell of the first Pico cell and the second Pico cell. At the same time, the determining module 702 further determines the cell of type a according to the cell identification information of type a. At this time, in combination with the first cell and the a type cell determined by the determining module 702, the target measurement cell of the "a type cell in the first cell" that conforms to the "first cell + a type" feature is determined.

In the sixth example, the MDT parameter configuration information may further include measurement area information for indicating the measurement area, cell frequency layer information for indicating a specific frequency point or a specific frequency band, and cell identification information for indicating a specific type. At this time, the determining module 702 is specifically configured to determine a specific frequency point in the measurement area or a specific type of cell in the specific frequency band as the target measurement cell.

For example, the MDT parameter configuration information includes measurement area information of the first cell, cell frequency layer information of the frequency point f2, and cell identification information of type a, that is, the MDT parameter configuration information is “first cell + frequency point β+a type”. Feature combination information. Then, the specific type of target measurement cell at this time is a cell of type a in the first cell using frequency point f2. The determining module 702 is configured to determine, within the measurement area, that is, in the first cell, the cell of type a, using the frequency point f2, is the target measurement cell.

Similarly, after receiving the measurement request message, the receiving module 701 obtains the MDT parameter configuration information, and the determining module 702 determines, according to the measurement area information of the first cell, that the first base station service includes the first Femto cell and the second Femto cell in the measurement area. And a first cell of the first Pico cell and the second Pico cell. At the same time, the determining module 702 determines the Femto cell with the frequency point β according to the cell frequency layer information of the frequency point f2. And, the determining module 702 determines the cell of type a according to the cell identification information of type a. At this time, in combination with the determined first cell, Femto cell, and a type cell, the "a type cell in the Femto cell in the first cell" that meets the "first cell + frequency point f2+a type" feature is determined. The target measures the cell. It should be noted that, when the MDT parameter configuration information is the feature combination information, the determining module 702 determines the cell range in the measurement area and determines the cell using a certain frequency point or frequency band in the process of determining the specific type of the target measurement cell. And the implementation process and order of determining a certain type of cell are not limited. Taking the example 4 as an example, the determining module 702 determines that the first intra-region Femto cell is the target measurement cell. The determining module 702 first determines the first cell according to the measurement area information, and further determines the cell frequency layer information according to the cell frequency layer information. The Femto cell is determined in the cell, and the Femto cell determined at this time is the target measurement cell; or the determining module 702 first determines all the Femto cells according to the cell frequency layer information, and further determines that the cell is located in the first cell according to the measurement area information. The Femto cell, the Femto cell determined at this time is the target measurement cell; and the determining module 702 determines the process of the first cell according to the measurement area information and the process of determining the Femto cell according to the cell frequency layer information, and the two processes are performed simultaneously. The results obtained by the combination are combined to finally determine the target measurement cell. For other implementations of the invention, the inventors will not enumerate them. Any implementation that achieves the objects of the invention is within the scope of the invention.

With the above technical solution of the present invention, in the user equipment provided by the present invention, after receiving the measurement request message sent by the network side, the determining module 702 determines the specificity in the measurement area according to the MDT parameter configuration information in the measurement request message. The type of target measurement cell; and in turn the MDT measurement module 703 performs MDT measurements for a particular type of target measurement cell, and finally the MDT measurement data acquisition module 704 acquires MDT measurement data. Therefore, the present invention does not need to perform MDT measurement on all types of cells in the measurement area, and can directly measure the specific type of cells in the measurement area that need to perform MDT measurement, thereby improving the efficiency of measuring resources and avoiding waste of measurement resources, and The measurement work of the UE is reduced.
