Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
For convenience of understanding, terms referred to in the embodiments of the present invention are explained below.
Serving Cell (Serving Cell): the Primary Cell (PCell) and the Secondary Cell (SCell) are cells that establish Radio Resource Control (RRC) connection with a terminal and provide service to the terminal.
Neighbor Cell (Neighbor Cell, NCell): also called as neighboring cells, refers to other cells except the serving cell to which the terminal is currently accessing. When the terminal is in the RRC connection state, the adjacent cells are measured, the measurement information is reported to the base station, and the base station indicates the terminal to switch between the service cell and the adjacent cells according to the measurement information.
Referring to fig. 1, a schematic structural diagram of a mobile communication system according to an embodiment of the present invention is shown. The mobile communication system may be an LTE system or a fifth generation mobile communication technology (5G), which is also called a New Radio (NR) system. The mobile communication system includes: access network device 120 and terminal 140.
The access network device 120 may be a base station, which may be configured to convert the received radio frame and IP packet message into each other, and may coordinate attribute management of the air interface. For example, the base station may be an evolved Node B (eNB or e-NodeB) in LTE, or a base station in 5G system that adopts a centralized distributed architecture.
Optionally, in the mobile communication system shown in fig. 1, different access network devices 120 correspond to respective radio signal coverage areas (circular areas with the access network devices 120 as centers), the radio signal coverage areas are referred to as cells, and an intersection exists between different cells. In other possible embodiments, 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 invention.
The access network device 120 and the terminal 140 establish a wireless connection over a wireless air interface. Optionally, the wireless air interface is based on an LTE standard; or the wireless air interface is a wireless air interface based on a 5G standard, for example, the wireless air interface is NR; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.
The method for reporting measurement information provided in each embodiment of the present invention is used in a process in which the terminal 140 reports the measurement result of the neighboring cell to the access network device 120 in an RRC connected state.
As shown in fig. 1, the area where the terminal 140 is located is covered by three cells, and in a connected state, the terminal 140 measures a serving cell and two neighboring cells respectively, determines whether the neighboring cells meet an Entering Condition (Entering Condition) according to measurement results of the serving cell and the neighboring cells and network configuration parameters, and sends the measurement results of the neighboring cells to the access network device when the neighboring cells meet the Entering Condition. Specifically, the entry conditions are as follows: mn + Ofn + Ocn-Hys > Mp + Ofp + Ocp + Off, wherein Mn is a measurement result of the adjacent cell, Ofn is a specific frequency offset of the adjacent cell, Ocn is a specific cell offset of the adjacent cell, Hys is a hysteresis parameter, Mp is a measurement result of the serving cell, 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 6 variable network configuration parameters (Ofn, Ocn, Hys, Ofp, Ocp, Off). Because the network configuration parameters are preset manually, when the network configuration parameters are unreasonable, the cell signal strength of the neighboring cell reported by the terminal finally may be lower than the cell signal strength of the serving cell, that is, reporting the measurement result of the neighboring cell with a poor signal. When the access network device switches the terminal to the neighboring cell according to the measurement result, the access network device still switches the terminal back to the original serving cell because the signal of the neighboring cell is poor, and frequent cell switching affects the normal communication of the terminal. In order to solve the above technical problem, in the embodiment of the present invention, after the terminal screens out candidate neighboring cells according to the entry condition, a target neighboring cell whose cell signal strength is greater than that of the serving cell is further screened out from the candidate neighboring cells, so that measurement information of the target neighboring cell is reported to the access network device, and it is ensured that the access network device switches the terminal to a neighboring cell with better signal strength according to the measurement information reported by the terminal, thereby avoiding frequent switching of a cell accessed by the terminal, and further improving communication quality of the terminal, which is described below with an exemplary embodiment.
Please refer to fig. 2, which shows a flowchart of a method for reporting measurement information according to an embodiment of the present invention, where the method for reporting measurement information is used for the terminal shown in fig. 1 as an example for description, the method may include the following steps.
In a connected state, the terminal measures a current access serving cell and each neighboring cell respectively to obtain corresponding measurement information, where the measurement information includes information such as cell Signal strength, cell Signal Quality (e.g., Signal-to-noise ratio), and cell identifier, and the cell Signal strength is represented by Reference Signal Receiving Power (RSRP) and/or Reference Signal Receiving Quality (RSRQ).
In a possible implementation, in the connected state, the terminal performs measurement on the serving cell and the neighboring cell at predetermined time intervals (for example, 460ms), or performs measurement on the serving cell at predetermined time intervals, and performs measurement on the neighboring cell when the measurement result indicates that the cell signal strength of the serving cell is lower than the threshold.
It should be noted that, when the terminal does not acquire the measurement information of the neighboring cell, the terminal stops reporting the measurement information to the access network device.
And aiming at each adjacent cell, the terminal determines a candidate adjacent cell from the adjacent cells according to the first measurement information of the service cell, the second measurement information of the adjacent cell and the network configuration parameters corresponding to the service cell and the adjacent cells.
In order to be compatible with the existing protocol, in a possible implementation manner, the terminal determines whether the neighboring cell meets the entry condition according to the first measurement information, the second measurement information of the neighboring cell and the network configuration parameter, and determines the neighboring cell meeting the entry condition as a candidate neighboring cell.
In the related art, when it is detected that the neighboring cell satisfies 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 invention, after determining the candidate neighbor cell, the terminal further screens out the candidate neighbor cell having the cell signal strength greater than that of the serving cell according to the first measurement information of the serving cell and the second measurement information of the candidate neighbor cell, and determines such candidate neighbor cell as the target neighbor cell.
In a possible implementation manner, the terminal obtains the serving cell signal strength included in the first measurement information and the neighboring cell signal strength (corresponding to the candidate neighboring cell) included in the second measurement information, and when the neighboring cell signal strength is greater than the serving cell signal strength, the terminal determines the candidate neighboring cell as the target neighboring cell; when the signal intensity of the neighbor cell is smaller than that of the serving cell, the terminal filters the candidate neighbor cell.
And step 204, reporting the second measurement information of the target neighbor cell to the access network equipment.
Further, after the terminal determines the target neighboring cell through twice screening, the second measurement information of the target neighboring cell is reported to the access network device. In a possible implementation manner, the terminal sends the second measurement information of the target neighboring cell to the access network device by reporting the MR
And after receiving the second measurement information, the access network equipment switches the terminal from the current serving cell to the target neighbor cell according to the cell identifier contained in the second measurement information.
In a possible implementation manner, when the second measurement information of at least two target neighboring cells is received, the access network device further switches the terminal to one of the target neighboring cells according to the load condition and the cell signal strength of each target neighboring cell.
In summary, in the embodiment of the present invention, the terminal first screens out the candidate neighboring cells according to the measurement information of the serving cell, the measurement information of the neighboring cells, and the network configuration parameter, and further screens out the target neighboring cell from the candidate neighboring cells, where the cell signal strength is greater than that of the serving cell, so as to finally report the measurement information of the target neighboring cell to the access network device, thereby 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, avoiding frequent switching of the cell accessed by the terminal, and further improving the communication quality of the terminal.
When the terminal reports the measurement information by using the measurement information reporting method shown in fig. 2, if the cell signal strengths of the serving cell and the target neighboring cell are very close to each other, the access network device switches the terminal from the serving cell to the target neighboring cell according to the measurement information, which does not significantly improve the communication quality, but may affect the communication quality due to cell switching. In order to avoid the above problem, in a possible implementation, the terminal further determines whether the serving cell and the candidate neighboring cell have a large difference according to a cell signal strength difference between the serving cell and the candidate neighboring cell, and determines the candidate neighboring cell as the target neighboring cell when the serving cell and the candidate neighboring cell have a large difference. The following description will be made by using exemplary embodiments.
Please refer to fig. 3, which shows a flowchart of a method for reporting measurement information according to an embodiment of the present invention, where the method for reporting measurement information is used for the terminal shown in fig. 1 as an example for description, the method may include the following steps.
The implementation of steps 301 and 302 is similar to that of steps 201 to 202, and this embodiment is not described herein again.
When the measurement information indicates that the neighbor cell signal strength of the candidate neighbor cell is better than the serving cell signal strength of the serving cell, the terminal calculates a cell signal strength difference between the candidate neighbor cell and the serving cell.
For example, when the cell signal strength in the measurement information is represented by RSRP, the serving cell signal strength is-90 dbm, and the neighbor cell signal strength is-85 dbm, the calculated cell signal strength difference is (-85) - (-90) ═ 5 dbm.
And step 304, when the cell signal strength difference value is greater than the strength difference threshold value, determining the candidate neighbor cell as a target neighbor cell.
After the cell signal strength difference is calculated, the terminal detects whether the cell signal strength difference is greater than a strength difference threshold, if the cell signal strength difference is greater than the strength difference threshold, the terminal determines the candidate neighbor cell as a target neighbor cell, and executes the following step 305; and if the cell signal intensity difference value is smaller than the intensity difference threshold value, the terminal filters the candidate adjacent cells.
When the serving cell signal strength of the serving cell is small, that is, the cell signal of the serving cell is weak, switching to an adjacent cell with high cell signal strength will greatly improve the communication quality; when the serving cell signal strength of the serving cell is high, that is, the cell signal of the serving cell is high, the handover to the neighboring cell with the high cell signal strength will not greatly improve the communication quality, but the handover will affect the communication quality. Therefore, for different signal strength levels of the serving cell, the terminal sets different strength difference thresholds in advance, and the subsequent terminal determines the target neighbor cell based on the corresponding strength difference threshold.
In one possible embodiment, as shown in fig. 4, this step includes the following steps.
In a possible implementation manner, the terminal sets a correspondence relationship between the cell signal strength and the cell signal strength level in advance, and illustratively, the correspondence relationship is shown in table one.
Watch 1
| Cell signal strength | Cell signal strength level |
| -140dbm to-110 dbm | 1 |
| -110dbm to-90 dbm | 2 |
| -90 to-50 dbm | 3 |
Correspondingly, the terminal determines the signal intensity level of the serving cell corresponding to the signal intensity of the serving cell according to the corresponding relation shown in the table one.
In a possible implementation manner, the correspondence is stored in a non-volatile memory (NV), so as to avoid data loss after the terminal is powered off and restarted.
For example, when the serving cell signal strength is-90 dbm, the terminal determines that the serving cell signal strength level is 3.
Aiming at different cell signal strength levels, corresponding strength difference threshold values are preset in the terminal, and the cell signal strength level and the strength difference threshold value are in positive correlation, namely the higher the cell signal strength level is, the larger the strength difference threshold value is, the lower the cell signal strength level is, and the smaller the strength difference threshold value is.
Illustratively, the correspondence between the cell signal strength level and the strength difference threshold is shown in table two.
Watch two
For example, when the terminal determines that the signal strength level of the serving cell is level 3, it further determines that the corresponding strength difference threshold is 7 dbm.
After determining the intensity difference threshold corresponding to the signal intensity level of the serving cell, the terminal further detects whether the cell signal intensity difference value between the serving cell and the candidate neighbor cell is greater than the intensity difference threshold, if so, the terminal determines the candidate neighbor cell as a target neighbor cell; if the number is smaller than the preset threshold, the terminal filters the candidate neighbor cells.
For example, when the signal strength of the serving cell is-90 dbm and the signal strength of the neighbor cell is-85 dbm, the terminal filters the candidate neighbor cell because the difference between the signal strengths of the serving cell and the neighbor cell is 5dbm < the strength difference threshold value of 7 dbm; when the signal strength of the serving cell is-120 dbm and the signal strength of the neighbor cell is-115 dbm, the terminal determines the candidate neighbor cell as the target neighbor cell because the difference value between the signal strengths of the serving cell and the neighbor cell is 5dbm and is larger than the intensity difference threshold value 2 dbm.
Under the condition that the signal of the serving cell is strong, the frequency of the terminal reporting the second measurement information is low because the corresponding reporting threshold is high (the intensity difference threshold is large), so that the influence of frequent cell switching of the terminal on the communication quality is avoided; and under the condition that the signal of the serving cell is weaker, the frequency of the terminal reporting the second measurement information is higher because the corresponding reporting threshold is lower (the intensity difference threshold is smaller), so that the terminal can be switched to the cell with a better signal, and the communication quality of the terminal is improved.
After the target adjacent cell is screened out by adopting the steps, the server further sends the second measurement information of the target adjacent cell to the access network equipment, so that the access network equipment can switch the terminal from the service cell to the target adjacent cell according to the second measurement information. The implementation of this step is similar to that of step 204, and this embodiment is not described herein again.
In summary, in the embodiment of the present invention, the terminal first screens out the candidate neighboring cells according to the measurement information of the serving cell, the measurement information of the neighboring cells, and the network configuration parameter, and further screens out the target neighboring cell from the candidate neighboring cells, where the cell signal strength is greater than that of the serving cell, so as to finally report the measurement information of the target neighboring cell to the access network device, thereby 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, avoiding frequent switching of the cell accessed by the terminal, and further improving the communication quality of the terminal.
In the embodiment, the terminal adjusts the intensity difference threshold according to the signal intensity of the serving cell, so that the frequency of reporting measurement information when the signal of the serving cell is strong is reduced, and the influence of frequent cell switching on communication is avoided; meanwhile, the probability that the terminal reports the measurement information when the serving cell signal is weak is improved, so that the terminal can be quickly switched to the adjacent cell with the better signal, and the communication quality of the terminal is improved.
In a possible embodiment, on the basis of fig. 2, as shown in fig. 5, step 205 is further included before step 203, with respect to the timing when the terminal screens the target neighbor cell from the candidate neighbor cells.
In a possible implementation manner, the services in the terminal correspond to different priorities according to the high and low demands of the services on the communication quality, wherein the higher the priority of the service is, the higher the demand of the service on the communication quality is indicated.
Illustratively, the priorities corresponding to different services in the terminal are shown in table three.
Watch III
| Business | Priority level |
| Voice call, video chat, online gaming | 1 |
| Video playing and webpage browsing | 2 |
| Mail receiving and sending | 3 |
Accordingly, step 203 may be replaced with step 203A.
Further, the terminal detects whether the priority of the currently executed service is higher than a priority threshold, and further deletes the target neighbor cell from the candidate neighbor cells when the priority of the currently executed service is higher than the priority threshold. Optionally, when the priority of the currently executed service is lower than the priority threshold, the terminal directly sends the second measurement information of the candidate neighbor cell to the server without performing target neighbor cell screening.
In the actual implementation process, when the voice call or online game service with high communication quality requirement is currently executed, the terminal further screens out a target adjacent cell, and the influence of frequently switching cells on the current service is avoided.
In another possible embodiment, on the basis of fig. 2, as shown in fig. 6, step 206 is further included before step 203.
In a possible implementation manner, when determining whether a target neighbor cell needs to be further screened from candidate neighbor cells, the terminal detects whether the cell switching frequency of the terminal is greater than a frequency threshold within a predetermined time period, if the cell switching frequency is greater than the frequency threshold, the terminal determines that measurement information reported recently is inaccurate, and screens the target neighbor cell from the candidate neighbor cells; if the cell switching frequency is smaller than the frequency threshold, the terminal determines that the recently reported measurement information is accurate, and directly reports the candidate neighbor cell to the access network equipment.
For example, the terminal detects whether the cell switching frequency of the terminal is greater than 1 time/second within the last 5 seconds.
Accordingly, step 203 may be replaced with step 203B.
Further, when the terminal detects that the cell switching frequency is greater than the frequency threshold, the terminal further screens out a target neighbor cell from the candidate neighbor cells.
For example, when the terminal detects that the cell switching frequency of the terminal is greater than 1 time/second in the last 5 seconds, the terminal further screens out the target neighbor cell from the candidate neighbor cells.
Referring to fig. 7, a block diagram of a measurement information reporting apparatus according to an embodiment of the present invention is shown, where the measurement information reporting apparatus may be implemented as part or all of the terminal 140 shown in fig. 1 through software, hardware, or a combination of the two.

and if the cell signal strength difference value is greater than the strength difference threshold corresponding to the signal strength grade of the service cell, determining the candidate neighbor cell as the target neighbor cell.
