"and/or", describing the association relationship of the associated objects, indicating that there may be three relationships, for example, A and/or B, which may indicate that there are three cases where A exists separately, A and B exist at the same time, and B exists separately. The character "/" generally indicates that the contextual object is an "or" relationship.

For ease of understanding, the nouns involved in the embodiments of the present application are explained below.

A serving cell (Serving Cell) includes a primary cell (PCell) and a secondary cell (SCell), and refers to a cell that establishes a Radio Resource Control (RRC) connection with a terminal and provides services for the terminal.

Neighbor Cell (NCell): Also referred to as a neighboring cell, the terminal is currently accessing other cells than the serving cell. When the terminal is in the RRC connected state, the neighboring cell is measured, and the measurement information is reported to the base station, and the base station instructs the terminal to switch between the serving cell and the neighboring cell according to the measurement information.

Please refer to FIG. 1 , which is a schematic structural diagram of a mobile communication system according to an embodiment of the present application. The mobile communication system may be an LTE system or a 5th generation mobile communication (5G), also known as a New Radio (NR) system. The mobile communication system includes an access network device 120 and a terminal 140.

The access network device 120 can be a base station, and the base station can be used to convert the received radio frame with the IP packet message, and can also coordinate the attribute management of the air interface. For example, the base station may be an evolved base station (eNB or e-NodeB) in LTE, or a base station employing a centralized distributed architecture in a 5G system.

Optionally, in the mobile communication system shown in FIG. 1, different access network devices 120 correspond to respective wireless signal coverage ranges (circular areas with the access network device 120 as a center), and the wireless signal coverage is called A cell, and there is an intersection between different cells. In other possible implementation manners, the same access network device 120 may correspond to multiple cells, and each cell corresponds to a different identifier, which is not limited in this embodiment of the present application.

The access network device 120 and the terminal 140 establish a wireless connection through the wireless air interface. Optionally, the wireless air interface is a wireless air interface based on the LTE standard; or the wireless air interface is a wireless air interface based on the 5G standard, for example, the wireless air interface is NR; or the wireless air interface may be a next generation mobile based on 5G. Wireless air interface for communication network technology standards.

Terminal 140 may be a device that provides voice and/or data connectivity to a user. The terminal can communicate with one or more core networks via a Radio Access Network (RAN), which can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket, handheld, computer built-in or in-vehicle mobile device. For example, Subscriber Unit, Subscriber Station, Mobile Station, Mobile, Remote Station, Access Point, Remote Terminal , Access Terminal, User Terminal, User Agent, User Device, or User Equipment.

The measurement information reporting method provided by the embodiments of the present application is used by the terminal 140 to report the measurement result of the neighboring cell to the access network device 120 in the RRC connected state.

As shown in FIG. 1 , the area where the terminal 140 is located is covered by three cells, and in the connected state, the terminal 140 measures the serving cell and the two neighboring cells respectively, and determines according to the measurement result of the serving cell and the neighboring cell and the network configuration parameter. Whether the neighboring cell meets the Entering Condition and sends the measurement result of the neighboring cell to the access network device when the neighboring cell satisfies the entry condition. Specifically, the entry condition is: Mn+Ofn+Ocn-Hys>Mp+Ofp+Ocp+Off, where Mn is the measurement result of the neighboring cell, Ofn is the specific frequency offset of the neighboring cell, and Ocn is the specific cell bias of the neighboring cell. Hys is a hysteresis parameter, Mp is a serving cell measurement result, Ofp is a specific frequency offset of the serving cell, Ocp is a specific cell offset of the serving cell, and Off is an offset parameter.

Obviously, the terminal needs to determine whether to report the measurement result of the neighboring cell to the access network device according to the six variable network configuration parameters (Ofn, Ocn, Hys, Ofp, Ocp, Off). Since the network configuration parameters are manually set in advance, when the network configuration parameters are unreasonable, the cell signal strength of the neighboring cell finally reported by the terminal may be lower than the cell signal strength of the serving cell, that is, the measurement result of the neighboring cell with poor reporting signal. When the access network device switches the terminal to the neighboring cell according to the measurement result, because the signal of the neighboring cell is poor, the access network device still switches the terminal back to the original serving cell, and frequent cell handover will affect the terminal. Normal communication. In order to solve the above technical problem, in the embodiment of the present application, after screening the candidate neighboring cell according to the foregoing entry condition, the terminal further selects the target neighboring cell whose cell signal strength is greater than the serving cell from the candidate neighboring cell, thereby measuring the target neighboring cell. The information is reported to the access network device, and the access network device switches the terminal to the neighboring cell with better signal strength according to the measurement information reported by the terminal, so as to avoid frequent handover of the cell accessed by the terminal, thereby improving the communication quality of the terminal. Description will be made using an illustrative embodiment. The measurement information reporting method provided by the embodiment of the present application includes:

Obtaining a serving cell signal strength in the first measurement information and a neighbor cell signal strength in the second measurement information;

The cell signal strength difference is calculated according to the signal strength of the serving cell and the signal strength of the neighboring cell.

Optionally, before determining the target neighboring cell included in the candidate neighboring cell according to the first measurement information and the second measurement information of each candidate neighboring cell, the method further includes:

Obtain the priority of the currently executed service, and the priority is used to indicate the service demand for communication quality;

If the priority of the currently performed service is higher than the priority threshold, the step of determining the target neighboring cell included in the candidate neighboring cell according to the first measurement information and the second measurement information of each candidate neighboring cell is performed.

Detecting whether a cell switching frequency within a predetermined duration is greater than a frequency threshold;

And if the cell switching frequency is greater than the frequency threshold, performing a step of determining, according to the first measurement information and the second measurement information of each candidate neighboring cell, the target neighboring cell included in the candidate neighboring cell.

Optionally, after the second measurement information of the target neighboring cell is reported to the access network device, the method further includes:

Calculating the proportion of the target neighboring cell in the candidate neighboring cell;

If the ratio is less than the proportional threshold, adjust the network configuration parameters.

Please refer to FIG. 2 , which is a flowchart of a method for reporting measurement information provided by an embodiment of the present application. The method for reporting the measurement information is used in the terminal shown in FIG. 1 as an example. The method may include the following. step.

Step 201: Acquire first measurement information of the serving cell and second measurement information of each neighboring cell, where the first measurement information and the second measurement information include cell signal strength.

In the connected state, the terminal performs measurement on the current access service cell and each neighboring cell, respectively, to obtain corresponding measurement information, where the first measurement information is Mp, and the second measurement information is Mn, and the measurement information includes Information such as cell signal strength, cell signal quality (such as signal-to-noise ratio), and cell identity. The signal strength of the cell uses Reference Signal Receiving Power (RSRP) and/or Reference Signal Receiving Quality (RSRQ). ) said. In a possible implementation manner, in the connected state, the terminal measures the serving cell and the neighboring cell every predetermined time interval (for example, 460 ms), or the terminal measures the serving cell every predetermined time interval, and measures When the result indicates that the cell signal strength of the serving cell is lower than the threshold, the neighboring cell is measured.

It should be noted that when the terminal does not obtain the measurement information of the neighboring cell, the terminal stops reporting the measurement information to the access network device.

Step 202: Determine a candidate neighboring cell according to the first measurement information, the second measurement information of each neighboring cell, and the network configuration parameter, where the network configuration parameter is used to indicate a cell offset of the serving cell and the neighboring cell.

For each neighboring cell, the terminal determines the candidate neighboring cell from the neighboring cell according to the first measurement information of the serving cell, the second measurement information of the neighboring cell, and the network configuration parameter corresponding to the serving cell and the neighboring cell.

In a possible implementation manner, the terminal determines, according to the first measurement information, the second measurement information of the neighboring cell, and the network configuration parameter, whether the neighboring cell satisfies an entry condition, and the neighboring cell that meets the entry condition is satisfied. Determine candidate neighbor cells.

Step 203: Determine, according to the first measurement information and the second measurement information of each candidate neighboring cell, a target neighboring cell included in the candidate neighboring cell, where the cell signal strength of the target neighboring cell is greater than the cell signal strength of the serving cell.

In the related art, when detecting that the neighboring cell meets the entry condition, the terminal directly reports the measurement information of the neighboring cell to the access network device, and the access network device can switch the terminal to the neighboring cell according to the measurement information. In the embodiment of the present application, after determining the candidate neighboring cell, the terminal further selects the candidate neighboring cell whose cell signal strength is greater than the serving cell according to the first measurement information of the serving cell and the second measurement information of the candidate neighboring cell, and Such candidate neighbor cells are determined as target neighbor cells.

In a possible implementation manner, the terminal acquires the serving cell signal strength included in the first measurement information and the neighbor cell signal strength (corresponding to the candidate neighboring cell) included in the second measurement information, where the neighbor cell signal strength is greater than the serving cell signal. When the strength is strong, the terminal determines the candidate neighboring cell as the target neighboring cell; when the neighboring cell signal strength is smaller than the serving cell signal strength, the terminal filters the candidate neighboring cell.

Step 204: Report second measurement information of the target neighboring cell to the access network device.

Further, after determining the target neighboring cell through the two screenings, the terminal reports the second measurement information of the target neighboring cell to the access network device. In a possible implementation, the terminal sends the second measurement information of the target neighboring cell to the access network device by reporting the MR.

After receiving the second measurement information, the access network device switches the terminal from the current serving cell to the target neighboring cell according to the cell identifier included in the second measurement information.

In a possible implementation manner, when receiving the second measurement information of the at least two target neighboring cells, the access network device further switches the terminal to one of the targets according to the load condition of each target neighboring cell and the cell signal strength. Neighboring cell.

In summary, in the embodiment of the present application, the terminal first filters the candidate neighboring cell according to the measurement information of the serving cell, the measurement information of the neighboring cell, and the network configuration parameter, and further filters out the cell signal strength from the candidate neighboring cell to be larger than the serving cell. The target neighboring cell, and finally the measurement information of the target neighboring cell is reported to the access network device, ensuring that the access network device switches the terminal to the neighboring cell with better signal strength according to the measurement information reported by the terminal, and avoids access to the terminal. The cell performs frequent handovers, thereby improving the communication quality of the terminal.

Generally, when the number of target neighboring cells that are finally reported is significantly different from the number of candidate neighboring cells, it indicates that the currently set network configuration parameters are unreasonable. In order to improve the accuracy of the selected candidate neighboring cells, it is possible. In the embodiment, after the terminal reports the second measurement information of the target neighboring cell to the access network device, the method further includes the following steps:

1. Calculate the proportion of the target neighboring cell in the candidate neighboring cell.

After the terminal filters out the target neighboring cell, the ratio of the target neighboring cell to the candidate neighboring cell is calculated, where the ratio is the number of the target neighboring cells/the number of the candidate neighboring cells.

For example, when the number of candidate neighboring cells is 4 and the number of target neighboring cells is 1, the calculated ratio is 1/4.

2. If the ratio is less than the proportional threshold, adjust the network configuration parameters.

When the ratio is less than the ratio threshold, it indicates that the candidate neighboring cell contains more neighboring cells with poor signals. To improve the recognition rate of such neighboring cells, the terminal adjusts the current network configuration parameters. For example, the ratio threshold is 1/2.

Optionally, the terminal adjusts the Off parameter and the Hys parameter in the network configuration parameter.

Illustratively, in combination with the example in the foregoing steps, the terminal adjusts the network configuration parameters because the proportion of the target neighboring cell in the candidate neighboring cell is less than a ratio threshold of 1/2.

When the terminal uses the measurement information reporting method shown in FIG. 2 to report the measurement information, if the cell signal strength of the serving cell and the target neighboring cell are very close, the access network device switches the terminal from the serving cell to the target neighboring cell according to the measurement information. It will significantly improve the communication quality, but will affect the communication quality due to cell handover. In order to avoid the above problem, in a possible implementation manner, the terminal further determines, according to the cell signal strength difference between the serving cell and the candidate neighboring cell, whether there is a large difference between the serving cell and the candidate neighboring cell, and there is a large difference between the two. When the difference is different, the candidate neighboring cell is determined as the target neighboring cell. The following description is made using the illustrative embodiments.

Please refer to FIG. 3 , which is a flowchart of a method for reporting measurement information provided by an embodiment of the present application. The method for reporting the measurement information is used in the terminal shown in FIG. 1 as an example. The method may include the following. step.

Step 301: Acquire first measurement information of the serving cell and second measurement information of each neighboring cell, where the first measurement information and the second measurement information include cell signal strength.

Step 302: Determine a candidate neighboring cell according to the first measurement information, the second measurement information of each neighboring cell, and the network configuration parameter, where the network configuration parameter is used to indicate a cell offset of the serving cell and the neighboring cell.

The implementation of the foregoing

steps

301 and 302 is similar to the steps 201 to 202, and details are not described herein again.

Step 303: Calculate a cell signal strength difference according to the first measurement information and the second measurement information of the candidate neighboring cell.

When the measurement information indicates that the neighbor cell signal strength of the candidate neighboring cell is better than the serving cell signal strength of the serving cell, the terminal calculates a cell signal strength difference between the candidate neighboring cell and the serving cell.

In a possible implementation, the terminal acquires the signal strength of the serving cell in the first measurement information and the signal strength of the neighboring cell in the second measurement information, and calculates the difference of the signal strength of the cell according to the signal strength of the serving cell and the signal strength of the neighboring cell. Value, where the cell signal strength difference = neighbor cell signal strength - serving cell signal strength.

For example, when the cell signal strength in the measurement information is represented by RSRP, and the signal strength of the serving cell is -90 dbm, and the signal strength of the neighboring cell is -85 dbm, the calculated difference of the signal strength of the cell is (-85)-(-90 ) = 5dbm.

Step 304: When the cell signal strength difference is greater than the strength difference threshold, determine that the candidate neighboring cell is the target neighboring cell.

After the cell signal strength difference is calculated, the terminal detects whether the cell signal strength difference is greater than the intensity difference threshold. If the cell signal strength difference is greater than the strength difference threshold, the terminal determines the candidate neighbor cell as the target neighbor cell, and performs the following step 305. If the cell signal strength difference is less than the intensity difference threshold, the terminal filters the candidate neighbor cells.

When the signal strength of the serving cell of the serving cell is small, that is, the cell signal of the serving cell is weak, the handover to the neighboring cell with higher cell signal strength will greatly improve the communication quality; and when the signal strength of the serving cell of the serving cell is relatively If the cell signal of the serving cell is strong, switching to the neighboring cell with higher cell signal strength will not greatly improve the communication quality, but the cell handover will affect the communication quality. Therefore, for different signal strength levels of the serving cell, the terminal presets different intensity difference thresholds, and the subsequent terminal determines the target neighboring cell based on the corresponding intensity difference threshold.

In a possible implementation manner, as shown in FIG. 4, this step includes the following steps.

Step 304A: Determine a serving cell signal strength level according to the serving cell signal strength included in the first measurement information.

In a possible implementation manner, the terminal presets a correspondence between a cell signal strength and a cell signal strength level. The corresponding relationship is shown in Table 1.

Table I

小区信号强度Cell signal strength	小区信号强度等级Cell signal strength level
-140dbm至-110dbm-140dbm to -110dbm	11
-110dbm至-90dbm-110dbm to -90dbm	22
-90dbm至-50dbm-90dbm to -50dbm	33

Correspondingly, the terminal determines the signal strength level of the serving cell corresponding to the signal strength of the serving cell according to the correspondence shown in Table 1.

In a possible implementation manner, the foregoing correspondence is stored in a non-volatile memory (NV), so as to avoid data loss after the terminal is restarted and restarted.

For example, when the signal strength of the serving cell is -90 dbm, the terminal determines that the signal strength level of the serving cell is level 3.

Step 304B: It is detected whether the cell signal strength difference is greater than the strength difference threshold corresponding to the serving cell signal strength level, and the serving cell signal strength level is positively correlated with the intensity difference threshold.

For different cell signal strength levels, the corresponding intensity difference threshold is preset in the terminal, and the cell signal strength level is positively correlated with the intensity difference threshold, that is, the higher the cell signal strength level, the larger the intensity difference threshold, and the lower the cell signal strength level. The smaller the intensity difference threshold.

Schematically, the correspondence between the cell signal strength level and the intensity difference threshold is as shown in Table 2.

Table II

小区信号强度等级Cell signal strength level	强度差阈值Intensity difference threshold
11	2dbm2dbm
22	4dbm4dbm
33	7dbm7dbm

For example, when the terminal determines that the signal strength level of the serving cell is 3, the terminal further determines that the corresponding intensity difference threshold is 7 dbm.

Step 304C: If the cell signal strength difference is greater than the strength difference threshold corresponding to the serving cell signal strength level, determine that the candidate neighboring cell is the target neighboring cell.

After determining the strength difference threshold corresponding to the signal strength level of the serving cell, the terminal further detects whether the cell signal strength difference between the serving cell and the candidate neighboring cell is greater than the strength difference threshold. If greater than, the terminal determines the candidate neighboring cell as the target neighboring cell. If less than, the terminal filters the candidate neighbor cell.

For example, when the signal strength of the serving cell is -90dbm and the signal strength of the neighboring cell is -85dbm, the signal strength difference between the two cells is 5dbm<the intensity difference threshold is 7dbm, so the terminal filters the candidate neighboring cell; when the signal strength of the serving cell When the signal strength of the neighboring cell is -115 dbm, the difference between the signal strength of the two cells is 5 dbm > the strength difference threshold is 2 dbm. Therefore, the terminal determines the candidate neighboring cell as the target neighboring cell.

When the signal of the serving cell is strong, the corresponding reporting threshold is high (the intensity difference threshold is large), so the frequency of reporting the second measurement information by the terminal is low, so as to avoid the impact of the terminal frequently switching the cell on the communication quality; In the case that the signal of the serving cell is weak, the corresponding reporting threshold is low (the intensity difference threshold is small), so the frequency at which the terminal reports the second measurement information is high, so that the terminal can switch to the cell with better signal. Improve the communication quality of the terminal.

Step 305: Report second measurement information of the target neighboring cell to the access network device.

After the target neighboring cell is filtered out by using the foregoing steps, the server further sends the second measurement information of the target neighboring cell to the access network device, so that the access network device switches the terminal from the serving cell to the target neighboring cell according to the second measurement information. The implementation of this step is similar to the foregoing step 204, and details are not described herein again.

In this embodiment, the terminal adjusts the strength difference threshold according to the signal strength of the serving cell, and reduces the frequency at which the terminal reports the measurement information when the serving cell signal is strong, and avoids frequent switching of the cell to affect the communication; at the same time, improving the signal of the terminal in the serving cell is weak. The probability of reporting the measurement information enables the terminal to quickly switch to the neighboring cell with better signal and improve the communication quality of the terminal.

For the timing of the terminal to select the target neighboring cell from the candidate neighboring cell, in a possible implementation manner, on the basis of FIG. 2, as shown in FIG. 5, the foregoing step 203 further includes step 205.

Step 205: Obtain a priority of the currently executed service, where the priority is used to indicate a service requirement for communication quality.

In a possible implementation manner, according to the requirement of the communication quality of the service, the services in the terminal correspond to different priorities, wherein the higher the priority of the service, the higher the requirement for the communication quality corresponding to the service.

Schematically, the priority corresponding to different services in the terminal is shown in Table 3.

Table 3

业务business	优先级priority
Volte语音通话、视频聊天、在线游戏Volte voice calls, video chat, online games	11
视频播放、网页浏览Video playback, web browsing	22
邮件收发Mail sending and receiving	33

Accordingly, step 203 can be replaced with step 203A.

Step 203A: If the priority of the currently performed service is higher than the priority threshold, determine the target neighboring cell included in the candidate neighboring cell according to the first measurement information and the second measurement information of each candidate neighboring cell.

Further, the terminal detects whether the priority of the currently performed service is higher than the priority threshold, and further deletes the target neighboring cell from the candidate neighboring cell when the priority of the currently performed service is higher than the priority threshold. Optionally, when the priority of the currently performed service is lower than the priority threshold, the terminal directly sends the second measurement information of the candidate neighboring cell to the server without performing target neighbor cell screening.

In the actual implementation process, when the current implementation of the Volte voice call or the online game service with high communication quality requirements, the terminal further filters out the target neighboring cell, and avoids frequent handover of the cell to affect the current service.

In another possible implementation manner, on the basis of FIG. 2, as shown in FIG. 6, step 203 is further included before step 206.

Step 206: Detect whether a cell switching frequency within a predetermined duration is greater than a frequency threshold.

In a possible implementation, when determining whether the terminal neighboring cell needs to be further filtered from the candidate neighboring cell, detecting whether the cell switching frequency of the terminal within the predetermined duration is greater than a frequency threshold, and if the cell switching frequency is greater than the frequency threshold, the terminal is It is determined that the recently reported measurement information is inaccurate, and the target neighboring cell is selected from the candidate neighboring cell. If the cell switching frequency is less than the frequency threshold, the terminal determines that the recently reported measurement information is accurate, and directly reports the candidate neighboring cell to the access network device.

For example, the terminal detects whether the cell switching frequency of the terminal is greater than 1 time/second in the last 5 seconds.

Accordingly, step 203 can be replaced with step 203B.

Step 203B: Determine, if the cell handover frequency is greater than the frequency threshold, the target neighboring cell included in the candidate neighboring cell according to the first measurement information and the second measurement information of each candidate neighboring cell.

Further, when the terminal detects that the cell handover frequency is greater than the frequency threshold, the terminal further filters the target neighboring cell from the candidate neighboring cell.

For example, when the terminal detects that the cell handover frequency of the terminal is greater than 1 time/second in the last 5 seconds, the terminal further selects the target neighboring cell from the candidate neighboring cell.
