Description

A base station, terminal, measurement control method, and measurement method

technical field

The present invention relates to the technical field of communication, and in particular to a base station, a terminal, a measurement control method and a measurement method.

Background technique

In an LTE (Long Term Evolution) communication system, handover of a UE (User Equipment, user equipment) can ensure service continuity when the UE moves between different cells. The handover of the UE is based on the UE's measurement of neighboring cells. Only the neighboring cells whose measured signal quality meets the conditions configured by the base station are allowed to be used as the handover target cell by the UE. In the LTE system, UE measurements are based on frequency points, and each frequency point is called a measurement object. The base station configures a measurement object, and the UE measures all cells under the frequency point.

In the case that the base station configures multiple measurement objects, the protocol of which measurement object the UE measures first is not specified, which may cause the base station to fail to make the UE handover to a cell with a higher priority. For example, the cell where the UE is located has two neighboring cells with different frequency points, the frequency point priority of cell 1 is high, and the frequency point priority of cell 2 is low. Since the base station does not know in advance which cell satisfies the handover condition, it needs to configure the UE to perform measurement on two frequency points at the same time. The existing protocol does not specify which frequency point the UE should measure first. If the UE measures the frequency point where cell 2 is located first, and both cells meet the handover conditions, the UE usually reports the measurement report of cell 2 to the base station first, and the base station will use Cell 2 serves as the target cell and instructs the UE to perform handover. Although the frequency point priority of cell 1 is high, the UE has no chance to handover to cell 1. Therefore, in the prior art, the base station has no way to control the handover of the UE to a high-priority target cell.

Detailed ways

The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

Embodiment one:

Referring to FIG. 1 , this embodiment shows a base station that can control a terminal to measure a cell according to a measurement priority of a frequency point. When the terminal is located at the edge of the current cell and cell handover may occur, the base station can control the terminal to measure neighboring cells according to the measurement priority set by the base station for the frequency point through the measurement configuration information delivered to the terminal. In this way, the base station controls the order in which the terminal measures the cells, and the measurement report that the terminal first feeds back to the base station is the measurement report of the cell with a higher measurement priority. When the base station controls the terminal to perform cell handover, the handed over cell is a cell with a higher measurement priority among neighboring cells. Instead of the prior art, the terminal randomly measures the first cell in the neighboring cell.

Referring to FIG. 1, the base station of this embodiment includes a processing module 11 and a sending module 12. The processing module 11 is used to configure the measurement configuration for the terminal when the terminal is located at the edge of the current cell. Information, measurement configuration information is used for the terminal to measure the neighboring cells of the current cell, including the measurement priority of the frequency point where each neighboring cell is located; the measurement priority is used for the terminal to measure the neighboring cells in the order of the measurement priority; send Module 12, configured to send measurement configuration information to the terminal.

In this embodiment, the base station can obtain the location of the terminal in the current cell (ie, the serving cell) according to the data interaction with the terminal. When the terminal is located at the edge of the current cell, the base station needs to control the terminal to perform cell handover, and The handover of the cell is based on the measurement of the cell by the terminal. In this embodiment, the processing module 11 of the base station configures the measurement configuration information of each neighboring cell of the current cell, that is, each neighboring cell has corresponding measurement configuration information. It can be understood that there may be inaccessible cells in the neighboring cells of the current cell where the terminal is located, so in order to avoid wasting resources and wasting the measurement time of the terminal, the measurement configuration information configured by the processing module 11 is used for the current The accessible neighboring cells among the neighboring cells of the cell are measured.

Generally, the measurement configuration information is mainly composed of measurement objects, report configurations, and other parameters. The measurement objects are the objects that the terminal performs measurement, mainly including the target measurement system and measurement frequency points. The measurement frequency points here are the frequency points where the neighboring cells are located. , so in this embodiment, the measurement priority in the measurement configuration information configured by the processing module 11 can actually be understood as the measurement priority of the measurement object. Generally, when configuring the measurement configuration information, the base station can obtain the measurement frequency point from the neighbor cell list of the current cell.

It can be foreseen that the neighboring cells of the current cell may be cells of the same frequency, or cells of different frequencies, cells of the same system, or cells of different systems, so the processing module 11 in this embodiment configures the type of measurement configuration information for the terminal Including: same-frequency/same-system adjacent cell measurement configuration information, different-frequency/different-system adjacent cell measurement configuration information. Therefore, this embodiment is applicable to handover of a terminal between a same-frequency/same-system cell and a different-frequency/different cell.

Generally, the sending module 12 can notify the terminal of the measurement configuration message through the MeasConfig information element in the RRC Connection Reconfiguration message. And according to the above description, it is conceivable that there may be cells with the same frequency or different frequency with the current cell in each neighboring cell. Therefore, after the sending module 12 sends the measurement configuration information to the terminal, the UE performs measurement according to the measurement priority configured by the base station, the measurement object with a high measurement priority is measured first, the measurement object with a low measurement priority is measured later, and the measurement objects with the same priority are measured by the UE Determines the measurement order.

Generally speaking, for a terminal, the measurement report of the cell measured first will be sent to the base station first, and if the base station judges that the cell meets the handover conditions, it can control the terminal to access the neighboring cell. Therefore, the base station in this embodiment can realize the preferential handover to the ideal neighbor cell by controlling the measurement order of the terminal to the neighbor cell.

Wherein, generally speaking, when a terminal switches a cell, it hopes to switch to a neighboring cell with a relatively high priority. Therefore, in this embodiment, the measurement priority in the measurement configuration information may be based on the neighbor cell of the current cell. The priority of the zone is set. The processing module 11 is configured to set the measurement priority of each neighboring cell according to the priority of each neighboring cell when configuring measurement configuration information for the terminal. The priority of the neighboring cell can be understood as the priority of the frequency point where the neighboring cell is located. Generally, the frequency point priority of the adjacent cell is higher, and the corresponding measurement priority is higher, and the frequency point priority of the adjacent cell is lower, and the corresponding measurement priority is lower. The frequency points have the same priority, and the corresponding measurement priority is the same.

Further, in this embodiment, the measurement priority may be indicated by existing parameters in the current protocol, for example: a specific Offset of the Frequency of the Neighborcell (Ofn) is used to indicate the measurement priority In addition, it is also possible to indicate the measurement priority by adding parameters to the measurement object or indicate the priority of the measurement object in other feasible ways. Optionally, the processing module 11 is configured to use the frequency specific offset of the adjacent cell in the frequency point where each adjacent cell is located in the measurement configuration information as an indication of the measurement priority; or add self-defined level identification information in the measurement configuration information as Indication of measurement priority.

The above-mentioned adjacent cell frequency-specific offset is set for a frequency point, and is used to adjust the UE to preferentially switch to a specific frequency point, and adjust the difficulty of cell handover to different frequency points. For example, when the terminal can switch from the current cell to two cells with different frequency points A and B, by increasing the frequency offset of frequency point A, the UE can be handed over to the cell with frequency point A more easily. Frequency offset can be positive or negative. If it is positive, the trigger condition for handover will be lowered, and the handover will be advanced; if it is negative, the trigger condition for handover will be increased, and the handover will be delayed. In this embodiment, the larger the frequency-specific offset of the adjacent cell means the higher the measurement priority of the measurement object, and the corresponding cell is firstly measured by the terminal.

Further, the base station in this embodiment also includes a base station receiving module, which is used to receive the measurement report of each neighboring cell obtained after the terminal measures each neighboring cell according to the configuration measurement information, and control the terminal to switch from the current cell to the current cell according to the measurement report. The neighbor cell with the highest measurement priority that satisfies the handover condition.

Using this embodiment, the base station can configure measurement configuration information for the terminal when the terminal is located at the edge of the current cell. The measurement configuration information is used to measure each neighboring cell of the current cell, including the measurement priority of the frequency point where each neighboring cell is located. The measurement priority is used for the terminal to measure the neighboring cells according to the order of the measurement priority; after the base station sends the configured configuration information to the terminal, the terminal can measure the neighboring cells according to the order of the measurement priority configured by the base station. For measurement, the measurement report of the cell with high measurement priority is sent to the base station first, so that the base station can switch the terminal to the cell with high measurement priority. Compared with the existing technology, the solution of this embodiment can realize effective The measurement sequence of the control terminal indirectly achieves the effect of controlling the terminal to switch to an ideal cell.

Embodiment two:

Referring to FIG. 2 , this embodiment shows a terminal that can receive the measurement configuration information delivered by the base station in Embodiment 1, and sequentially switch neighboring cells according to the measurement configuration information.

The terminal in this embodiment includes: a receiving module 21, configured to receive the measurement configuration information of each neighboring cell of the current cell sent by the base station, and the measurement configuration information includes the measurement priority of each frequency point where each neighboring cell is located; a measurement module 22, configured to The order of measurement priority in the measurement configuration information of each neighboring cell is measured for each neighboring cell.

Generally, the base station can obtain the position of the terminal in the current cell (ie, the serving cell) according to the data interaction with the terminal. When the terminal is located at the edge of the current cell, the base station can detect the position of the terminal in the cell in real time, and then Configure the measurement configuration information, so generally, when the terminal is located at the edge of the current cell, it will receive the information including the measurement configuration information of the neighboring cell.

It can be understood that there may be inaccessible cells in the neighboring cells of the current cell where the terminal is located. Therefore, further, in order to avoid wasting resources and wasting measurement time of the terminal, the measurement configuration information issued by the base station is used to measure the accessible neighboring cells in the neighboring cells of the current cell.

Generally, the measurement configuration information is mainly composed of measurement objects, report configurations, and other parameters. The measurement objects are the objects that the terminal performs measurement, mainly including the target measurement system and measurement frequency points. The measurement frequency points here are the frequency points where the neighboring cells are located. , so in this embodiment, the measurement priority in the measurement configuration information delivered by the base station can actually be understood as the measurement priority of the measurement object.

It can be foreseen that the neighboring cells of the current cell may be cells of the same frequency or different frequencies, cells of the same system or cells of different systems, so the types of measurement configuration information in this embodiment include: same frequency/same frequency System adjacent cell measurement configuration information, inter-frequency/inter-system adjacent cell measurement configuration information. The measurement of the measurement module 22 in this embodiment includes the measurement of same-frequency/same-system cells and different-frequency/different cells.

Generally, the base station can notify the terminal of the measurement configuration information through the MeasConfig information element in the RRC Connection Reconfiguration message. After the terminal receives the measurement configuration information, the measurement module 22 performs measurement according to the measurement priority configured by the base station. The measurement object (cell) with a high measurement priority is measured first, and the measurement object (cell) with a low measurement priority is measured later. The measurement priority Similarly, the measurement sequence is determined by the UE.

Generally speaking, for a terminal, the measurement report of the cell measured first will be sent to the base station first, and if the base station judges that the cell meets the handover conditions, it can control the terminal to access the neighboring cell. Therefore, the base station in this embodiment can realize the preferential handover to the ideal neighbor cell by controlling the measurement order of the terminal to the neighbor cell.

Wherein, generally speaking, when a terminal switches a cell, it hopes to switch to a neighboring cell with a relatively high priority. Therefore, in this embodiment, the measurement priority in the measurement configuration information may be based on the neighbor cell of the current cell. The priority of the zone is set. The priority of the neighboring cell can be understood as the priority of the frequency point where the neighboring cell is located. Generally, the frequency point priority of the adjacent cell is higher, and the corresponding measurement priority is higher, and the frequency point priority of the adjacent cell is lower, and the corresponding measurement priority is lower. The frequency points have the same priority, and the set measurement priority is the same.

Further, in this embodiment, the measurement priority may be indicated by a parameter that already exists in the current protocol, for example: a specific Offset of the Frequency of the Neighbourcell (Ofn); in addition, it may also be indicated by Add new parameters to the measurement object to indicate the measurement priority or indicate the priority of the measurement object in other feasible ways. Optionally, in the measurement configuration information, the specific offset of the adjacent cell frequency of the frequency point where the adjacent cell of the current cell is located is an indication of the measurement priority; or in the measurement configuration information, the user-defined level identification information is newly added, and the level identification information is used Used to indicate measurement priority.

The above-mentioned adjacent cell frequency-specific offset is set for a frequency point, and is used to adjust the UE to preferentially switch to a specific frequency point, and adjust the difficulty of cell handover to different frequency points. For example, when the terminal can switch from the current cell to two cells with different frequency points A and B, by increasing the frequency offset of frequency point A, the UE can be handed over to the cell with frequency point A more easily. Frequency offset can be positive or negative. If it is positive, the trigger condition for handover will be lowered, and the handover will be advanced; if it is negative, the trigger condition for handover will be increased, and the handover will be delayed. In this embodiment, the larger the frequency-specific offset of the adjacent cell means the higher the measurement priority of the measurement object, and the corresponding cell is firstly measured by the terminal.

Further, the terminal in this embodiment further includes a terminal sending module, configured to report a measurement report to the base station after the measurement module completes the measurement of the neighboring cell. It can be understood that the measurement report of the neighboring cell that is preferentially measured is completed first, and will be sent to the base station first.

The terminal using this embodiment can receive the measurement configuration information of each neighboring cell of the current cell issued by the base station. The measurement configuration information includes the measurement priority of the frequency point where each neighboring cell is located; Neighboring cells of the current cell are measured. Therefore, the measurement report of the cell with high measurement priority can be sent to the base station first, which is beneficial for the base station to switch to the ideal target cell.

Embodiment three:

Referring to FIG. 3, this embodiment shows a measurement control method, which is applicable to the base station in Embodiment 1, including:

S301. When the terminal is located at the edge of the current cell, configure measurement configuration information for the terminal; where the measurement configuration information is used for the terminal to measure each neighboring cell of the current cell, including the measurement priority of the frequency point where each neighboring cell is located; measure Priority is used for the terminal to measure neighboring cells according to the order of measurement priority;

S302. Send the measurement configuration information to the terminal.

In this embodiment, what is configured in S301 is the measurement configuration information of each neighboring cell of the current cell, that is, each neighboring cell has corresponding measurement configuration information. It can be understood that there may be inaccessible cells in the neighboring cells of the current cell where the terminal is located, so in order to avoid wasting resources and wasting measurement time of the terminal, further, in S301, the configured measurement configuration information is used The measurement is performed on the accessible neighboring cells in the neighboring cells of the current cell. Generally, when configuring the measurement configuration information, the base station can obtain the measurement frequency point from the neighbor cell list of the current cell. When obtaining measurement frequency points, neighbor cells on the blacklist or unhandoverable neighbor cells can be filtered out.

Generally, the measurement configuration information is mainly composed of measurement objects, report configurations, and other parameters. The measurement objects are the objects that the terminal performs measurement, mainly including the target measurement system and measurement frequency points. The measurement frequency points here are the frequency points where the neighboring cells are located. , so the measurement priority in the measurement configuration information configured in S301 can actually be understood as the measurement priority of the measurement object.

It can be foreseen that the neighboring cells of the current cell may be cells of the same frequency or different frequencies, cells of the same system or cells of different systems, so the types of measurement configuration information configured for the terminal in S301 include: same frequency/ Measurement configuration information of neighboring cells of the same system, measurement configuration information of neighboring cells of different frequency/different systems. Therefore, this embodiment is applicable to handover of a terminal between a same-frequency/same-system cell and a different-frequency/different cell.

Generally, in S302, the measurement configuration information may be notified to the terminal through the MeasConfig information element in the RRC Connection Reconfiguration message. It is conceivable that there may be cells with the same frequency and different frequencies with the current cell in each neighboring cell. Therefore, after the measurement configuration information is sent to the terminal, the UE will perform measurement according to the measurement priority configured by the base station. The measurement object with a high measurement priority will be measured first, and the measurement object with a low measurement priority will be measured later, and the measurement object with the same priority will be determined by the UE. order.

Generally speaking, for a terminal, the measurement report of the cell measured first will be sent to the base station first, and if the base station judges that the cell meets the handover conditions, it can control the terminal to access the neighboring cell. Therefore, the base station in this embodiment can realize the preferential handover to the ideal neighbor cell by controlling the measurement order of the terminal to the neighbor cell.

Among them, generally speaking, when a terminal performs cell handover, it hopes to switch to a neighboring cell with a relatively high priority. Therefore, when configuring measurement configuration information for the terminal in S301, set the measurement parameters of each neighboring cell according to the priority of each neighboring cell. priority. The priority of the neighboring cell can be understood as the priority of the frequency point where the neighboring cell is located. Generally, the frequency point priority of the adjacent cell is higher, and the corresponding measurement priority is higher, and the frequency point priority of the adjacent cell is lower, and the corresponding measurement priority is lower. The frequency points have the same priority, and the set measurement priority is the same.

Further, the measurement priority may be indicated by existing parameters in the current protocol, for example: a specific Offset of the Frequency of the Neighbor cell (Ofn) is used to indicate the measurement priority; in addition, The measurement priority may be indicated by adding a parameter to the measurement object, or the priority of the measurement object may be indicated in other feasible ways. Therefore, when configuring measurement configuration information for the terminal, setting the measurement priority of each neighboring cell according to the priority of each neighboring cell includes taking the specific offset of the frequency of the adjacent cell at the frequency point where the neighboring cell of the current cell is located in the measurement configuration information as the measurement priority level; or add custom level identification information in the measurement configuration information as the information indicating the measurement priority. Wherein, the level identification information may be represented by the priority of the cell. For example, the priority of cell A is 2, and the priority of cell B is 3. You can write 2 in the new level identification information field of the measurement configuration information of cell A, and write the level identification information of the new measurement configuration information of cell B. Write 3 in the field.

The above-mentioned adjacent cell frequency-specific offset is set for frequency points. In this embodiment, the larger the adjacent cell frequency-specific offset, the higher the measurement priority of the measurement object, and the corresponding cell will be measured by the terminal first.

Further, after S302, it also includes: the measurement report of each neighboring cell obtained after the receiving terminal measures each neighboring cell according to the configured measurement information, and according to the measurement report, the control terminal switches from the current cell to the measurement priority cell that satisfies the switching condition. highest neighbor.

Using the measurement control method in this embodiment, the base station can configure measurement configuration information for the terminal when the terminal is located at the edge of the current cell. The measurement configuration information is used to measure each neighboring cell of the current cell, including the frequency The measurement priority of the point; after the base station sends the configured configuration information to the terminal, the terminal can preferentially measure the neighboring cells with high measurement priority, and send the measurement report of the cell with high measurement priority to the base station. This base station can implement handover of the terminal to a cell with a high measurement priority. Compared with the prior art, the solution of this embodiment can realize the effective control of the measurement sequence of the terminal by the base station, and indirectly achieve the effect of controlling the handover of the terminal to an ideal cell.

The measurement of the measurement module 22 in this embodiment includes the measurement of same-frequency/same-system cells and different-frequency/different cells.
