However, after the mobile terminal performs cell handover, although the signal strength of the neighboring cell is good, the signal quality may be poor, and the phenomena of poor call voice quality and even call drop are likely to occur.

Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart illustrating a method for reporting signal strength according to an embodiment of the present invention, where the method may be executed by a device for reporting signal strength, where the device may be implemented by software and/or hardware, and may be generally integrated in a mobile terminal. As shown in fig. 1, the method includes:
step 101, obtaining a first signal quality of a current serving cell and a second signal quality of an adjacent non-serving cell.
The current serving cell may be understood as a cell in which the mobile terminal is in wireless connection with the network side, that is, the current serving cell is a cell providing service for network data transmission of the mobile terminal, and a cell within a coverage area of the current serving cell or around the current serving cell may be referred to as an adjacent non-serving cell or, for short, an adjacent cell. During the movement of the mobile terminal, the handover of the cell usually occurs between the current serving cell and the adjacent non-serving cell, that is, between the serving cell and the adjacent cell.
Alternatively, the signal quality may be expressed as a signal-to-noise ratio, which is the ratio of the effective signal power to the noise signal power. Generally, the larger the signal-to-noise ratio is, the larger the effective signal power is relative to the noise signal power is, and the better the signal quality is; conversely, the smaller the signal-to-noise ratio, the lower the effective signal power relative to the noise signal power, and the worse the signal quality.
In the embodiment of the present application, a first signal quality of a current serving cell of a mobile terminal and a second signal quality of an adjacent non-serving cell are obtained, that is, the first signal quality represents the signal quality of the current serving cell of the mobile terminal, and the second signal quality represents the signal quality of the current adjacent non-serving cell of the mobile terminal. Alternatively, the Synchronization Channel (SCH) of the neighboring non-serving cell may be acquired, and the Base Station Identity Code (BSIC) corresponding to the neighboring non-serving cell is determined through the SCH, and then the signal quality of the cell corresponding to the BSIC is determined based on the BSIC, and is used as the second signal quality of the non-neighboring serving cell. In the mobile terminal moving process, the network side of the mobile communication system usually sends a neighboring cell list (i.e. a list of non-serving cells neighboring to the current serving cell) around the serving cell to the mobile terminal of the current serving cell in a broadcast manner, and the mobile terminal measures the second signal quality of each neighboring non-serving cell included in the list according to the neighboring cell list. As the mobile terminal moves continuously, the serving cell of the mobile terminal changes accordingly, and the number and the position of non-serving cells adjacent to the serving cell also change accordingly.
Step 102, when the first signal quality is higher than the second signal quality, determining a signal strength bias value based on the second signal quality.
In the embodiment of the present application, the first signal quality of the current serving cell and the second signal quality of the neighboring non-serving cell are determined. Optionally, if the signal quality includes a signal-to-noise ratio, determining the first signal quality and the second signal quality, that is, determining the signal-to-noise ratio of the current serving cell and the signal-to-noise ratio of the neighboring non-serving cell, and when the signal-to-noise ratio of the current serving cell is greater than the signal-to-noise ratio of the neighboring non-serving cell, indicating that the signal quality of the current serving cell is higher than the signal quality of the neighboring non-serving cell; otherwise, when the signal-to-noise ratio of the current serving cell is smaller than the signal-to-noise ratio of the adjacent non-serving cell, it indicates that the signal quality of the current serving cell is lower than the signal quality of the adjacent non-serving cell. When the first signal quality is higher than the second signal quality, a signal strength offset value corresponding to the second signal quality is determined based on the second signal quality. The first signal quality is higher than the second signal quality, which can be understood as that the call voice quality of the mobile terminal is better than the call voice quality of the mobile terminal in the adjacent non-serving cell during the GSM network call of the current serving cell.
It can be appreciated that the signal strength offset value is associated with a second signal quality of the neighboring non-serving cell. Optionally, determining a signal strength offset value based on the second signal quality includes: acquiring a preset functional relation between signal quality and signal strength bias; determining a signal strength bias value corresponding to the second signal quality based on the functional relationship with the second signal quality; wherein the signal strength offset value is inversely related to the second signal quality. Optionally, determining a signal strength offset value based on the second signal quality includes: acquiring a preset corresponding relation table between signal quality and signal strength bias; and determining a signal strength offset value corresponding to the second signal quality according to the second signal quality and the corresponding relation table between the signal quality and the signal strength offset.
It should be noted that, in the embodiments of the present application, the manner of determining the signal strength offset value based on the second signal quality is not limited.
And 103, determining the target signal strength according to the first signal strength of the adjacent non-service cell and the signal strength offset value.
Wherein the target signal strength is a difference between the first signal strength and the signal strength offset value.
In the embodiment of the present application, the signal strength may be understood as the effective signal power, and the larger the effective signal strength is, the larger the signal strength is, whereas the smaller the effective signal strength is, the smaller the signal strength is. A first signal strength of the neighboring non-serving cell is obtained, and a target signal strength is determined according to the first signal strength and the signal strength offset value determined in step 102, wherein the target signal strength is a difference between the first signal strength and the signal strength offset value. It can be understood that, when the first signal quality of the current serving cell is higher than the second signal quality of the second adjacent non-serving cell, a certain signal strength offset value is subtracted from the first signal strength of the adjacent non-serving cell, where the signal strength offset value is associated with the second signal quality, that is, the measured first signal strength of the non-serving cell is reduced by a certain amount to obtain a target signal strength, so that the target signal strength is reported to the network side as the signal strength of the adjacent non-serving cell in a subsequent step.
And step 104, taking the target signal strength as the signal strength of the adjacent non-service cell in a measurement report, and reporting the measurement report to a network side.
Illustratively, when the mobile terminal performs cell handover, the network side issues parameters such as a neighboring non-serving cell to be measured and a measurement amount and a reporting rule to the mobile terminal through a measurement control signaling, and then measures the neighboring non-serving cell based on the measurement control signaling issued by the network side during the moving process of the mobile terminal, generates a measurement report according to the measurement result, and sends the measurement report to the network side. In this embodiment of the present application, the target signal strength determined in step 103 is used as the signal strength of the neighboring non-serving cell in the measurement report, and the measurement report is reported to the network side. It can be understood that the signal strength (target signal strength) of the biased neighboring non-serving cell is reported to the network side, so that the network side determines whether to instruct the mobile terminal to perform the handover operation of the serving cell according to the signal strength of the biased neighboring non-serving cell.
It can be understood that, when the first signal quality of the current serving cell of the mobile terminal is higher than the second signal quality of the neighboring non-serving cell, the difference between the first signal strength of the neighboring non-serving cell and the signal strength offset value is taken as the signal strength of the neighboring non-serving cell in the measurement report, and the measurement report is reported to the network side, so that the network side determines whether to instruct the mobile terminal to perform the serving cell handover based on the adjusted signal strength of the neighboring non-serving cell, and can avoid switching the mobile terminal to the cell with high signal strength but poor signal quality as much as possible.
In the signal strength reporting method provided in the embodiment of the present application, a first signal quality of a current serving cell and a second signal quality of an adjacent non-serving cell are obtained, and when the first signal quality is higher than the second signal quality, a signal strength offset value is determined based on the second signal quality, and then a target signal strength is determined according to the first signal strength and the signal strength offset value of the adjacent non-serving cell, where the target signal strength is a difference between the first signal strength and the signal strength offset value, and finally the target signal strength is used as the signal strength of the adjacent non-serving cell in a measurement report, and the measurement report is reported to a network side. By adopting the technical scheme, the probability that the mobile terminal switches the service cell to the adjacent cell with poor signal quality can be effectively reduced, so that the mobile terminal can be kept or switched to the cell with high signal strength and good signal quality as far as possible, the conversation voice quality of the mobile terminal can be effectively improved, and the occurrence of call drop phenomenon can be reduced.
In some embodiments, when the first signal quality is lower than the second signal quality, the first signal strength is taken as the signal strength of the neighboring non-serving cell in a measurement report, and the measurement report is reported to a network side. It can be understood that, when the first signal quality of the current serving cell of the mobile terminal is lower than the second signal quality of the neighboring non-serving cell, the first signal strength of the neighboring non-serving cell is not subjected to offset adjustment, and the first signal strength is directly used as the signal strength of the neighboring non-serving cell in the measurement report, so that the network side directly determines whether to instruct the mobile terminal to perform the serving cell handover according to the first signal strength. It can be further understood that, when the signal quality of the neighboring non-serving cell is higher than the signal quality of the current serving cell, if the network side directly instructs the mobile terminal to perform the handover operation of the serving cell according to the first signal strength of the neighboring non-serving cell, it indicates that the first signal strength of the neighboring non-serving cell is higher than the signal strength of the current serving cell, and meanwhile, the signal quality of the neighboring non-serving cell is higher than the signal quality of the current serving cell, so that after the mobile terminal performs the handover of the serving cell, not only the occurrence of the call drop phenomenon can be avoided, but also the call voice quality of the mobile terminal can be further improved. If the network side does not indicate the mobile terminal to perform the handover operation of the serving cell directly according to the first signal strength of the adjacent non-serving cell, it indicates that the first signal strength of the adjacent non-serving cell is smaller than the signal strength of the current serving cell, and the mobile terminal continues to maintain the current serving cell for conversation.
In some embodiments, when the first signal quality is lower than the second signal quality, determining whether the second signal quality is greater than a preset quality threshold, if so, taking the first signal strength as the signal strength of the neighboring non-serving cell in a measurement report, and reporting the measurement report to a network side; or, if so, determining a signal strength offset value based on the second signal quality, and performing subsequent determination of a target signal strength according to the first signal strength of the adjacent non-serving cell and the signal strength offset value; wherein the target signal strength is a difference between the first signal strength and the signal strength offset value; and taking the target signal strength as the signal strength of the adjacent non-service cell in a measurement report, and reporting the measurement report to related operations of a network side. The advantage of such an arrangement is that although the second signal quality of the neighboring non-serving cell is lower than the first signal quality of the current serving cell, since the second signal quality is greater than the preset quality threshold, it indicates that the signal quality of the neighboring non-serving cell is not too poor, and even if the network side instructs the mobile terminal to switch the serving cell to the neighboring non-serving cell according to the measurement report, the impact on the call voice quality of the mobile terminal is not so great, and no obvious call drop occurs.
In some embodiments, after reporting the measurement report to the network side, the method further includes: receiving a cell switching instruction issued by a network side; when the target signal intensity is greater than the signal intensity of the current service cell, a network side issues a cell switching instruction; switching the current serving cell to the neighboring non-serving cell based on the cell switching instruction. It can be understood that, after receiving the measurement report sent by the mobile terminal, the network side determines whether the target signal strength in the measurement report is greater than the signal strength of the current serving cell, that is, the target signal strength after offsetting the first signal strength of the adjacent non-serving cell is compared with the signal strength of the current serving cell, when the target signal strength is greater than the signal strength of the current serving cell, it is indicated that the signal strength of the adjacent non-serving cell is much greater than the signal strength of the current serving cell, the network side issues a cell switching instruction to the mobile terminal, and the mobile terminal receives the cell switching instruction and switches the current serving cell to the adjacent non-serving cell.
Fig. 2 is a schematic flow chart of another method for reporting signal strength according to an embodiment of the present application, and as shown in fig. 2, the method includes:
step 201, obtaining a first signal quality of a current serving cell and a second signal quality of an adjacent non-serving cell.
Step 202, when the first signal quality is higher than the second signal quality, obtaining a preset functional relationship between the signal quality and the signal strength bias.
Step 203, determining a signal strength bias value corresponding to the second signal quality based on the functional relation between the second signal quality and the second signal quality.
Wherein the signal strength offset value is inversely related to the second signal quality.
For example, the signal quality is expressed as a signal-to-noise ratio, and the functional relationship between the signal quality and the signal strength offset can be understood as a functional relationship between the signal-to-noise ratio and the signal strength offset. For example, the functional relationship between the signal-to-noise ratio and the signal strength offset can be expressed as P ═ f (SNR), where P denotes the signal-to-noise ratio and SNR denotes the signal strength offset, and the signal-to-noise ratio is inversely related to the signal strength offset, i.e., the smaller the signal-to-noise ratio, the larger the signal strength offset; conversely, the greater the signal-to-noise ratio, the smaller the signal strength bias. That is, the higher the signal quality of the adjacent non-serving cell is, the smaller the offset amount for reducing the signal strength of the adjacent non-serving cell is; conversely, the lower the signal quality of the neighboring non-serving cell, the greater the amount of offset by which the signal strength of the neighboring non-serving cell is reduced. Alternatively, P ═ f (SNR) 20-2 SNR.
In the embodiment of the present application, when the first signal quality is higher than the second signal quality, the obtained second signal quality value (e.g., signal-to-noise ratio) may be directly substituted into the functional relation P ═ f (snr) between the signal quality and the signal strength offset, and the calculated value may be used as the signal strength offset value corresponding to the second signal quality. For example, if the SNR of a certain neighboring non-serving cell is 8dBm, the SNR is substituted into the formula P ═ f (SNR) ═ 20-2SNR, and P ═ 4dBm can be obtained, that is, the signal strength of the neighboring non-serving cell is reduced by 4 dBm.
And step 204, determining the target signal strength according to the first signal strength of the adjacent non-service cell and the signal strength offset value.
Wherein the target signal strength is a difference between the first signal strength and the signal strength offset value.
Step 205, taking the target signal strength as the signal strength of the neighboring non-serving cell in the measurement report, and reporting the measurement report to the network side.
In the signal strength reporting method provided in the embodiment of the present application, when a first signal quality of a current serving cell of a mobile terminal is higher than a second signal quality of an adjacent non-serving cell, a signal strength offset value corresponding to the second signal quality is determined based on the second signal quality and a preset functional relationship between the signal quality and the signal strength offset; the method comprises the steps of determining the signal strength bias value of a first non-serving cell in a measurement report, reporting the measurement report to a network side, and determining whether to instruct a mobile terminal to switch a serving cell or not according to the adjusted signal strength of the adjacent non-serving cell by the network side.
Fig. 3 is a schematic flow chart of another method for reporting signal strength according to an embodiment of the present application, and as shown in fig. 3, the method includes:
step 301, obtaining a first signal quality of a current serving cell and a second signal quality of an adjacent non-serving cell.
Step 302, when the first signal quality is higher than the second signal quality, obtaining a preset corresponding relation table between the signal quality and the signal strength bias.
Step 303, determining a signal strength offset value corresponding to the second signal quality according to the second signal quality and the correspondence table between the signal quality and the signal strength offset.
The correspondence table between the signal quality and the signal strength offset may be understood as an association table between the signal quality and the signal strength offset, that is, the correspondence table may be stored in the mobile terminal in advance. Optionally, when the mobile terminal needs to determine the signal strength offset value corresponding to the second signal quality of the adjacent non-serving cell, the corresponding relationship table between the signal quality and the signal strength offset stored in other mobile terminals or the server may be directly called. Optionally, the table of correspondence between signal quality and signal strength offset may be generated as follows: the method comprises the steps of obtaining a plurality of different signal qualities of a plurality of adjacent cells, and ensuring that a signal strength offset value is determined on the premise of not switching a mobile terminal to the adjacent cell when the signal quality of the adjacent cell is lower than that of a current service cell. And establishing a corresponding relation table between the signal quality and the signal strength offset based on a plurality of different signal qualities and the correspondingly determined signal strength offset values. For example, the signal quality is expressed by the signal-to-noise ratio, and the table of the correspondence between the signal quality and the signal strength offset may also be understood as the table of the correspondence between the signal-to-noise ratio and the signal strength offset.
In the embodiment of the present application, when the first signal quality is higher than the second signal quality, the signal strength offset value corresponding to the obtained second signal quality value (e.g., signal-to-noise ratio) may be directly looked up in the correspondence table between the signal quality and the signal strength offset.
Step 304, determining a target signal strength according to the first signal strength of the neighboring non-serving cell and the signal strength offset value.
Wherein the target signal strength is a difference between the first signal strength and the signal strength offset value.
Step 305, taking the target signal strength as the signal strength of the adjacent non-serving cell in the measurement report, and reporting the measurement report to the network side.
The signal strength reporting method provided in the embodiment of the present application, when the first signal quality of the current serving cell of the mobile terminal is higher than the second signal quality of the neighboring non-serving cell, determines the signal strength offset value corresponding to the second signal quality according to the second signal quality and the corresponding relation table between the signal quality and the signal strength offset, and uses the difference between the first signal strength and the signal strength offset value of the neighboring non-serving cell as the signal strength of the neighboring non-serving cell in the measurement report, and reports the measurement report to the network side, so that the network side determines whether to instruct the mobile terminal to perform the serving cell handover based on the adjusted signal strength of the neighboring non-serving cell, and can accurately and quickly determine the signal strength offset value corresponding to the second signal quality, thereby being beneficial to accurately and effectively reducing the probability that the mobile terminal switches the serving cell to the neighboring cell with the poor signal quality, the mobile terminal is kept or switched to the cell with high signal strength and good signal quality as much as possible, so that the call voice quality of the mobile terminal can be effectively improved, and the occurrence of call drop phenomenon is reduced.
Fig. 4 is a schematic flow chart of another method for reporting signal strength according to an embodiment of the present application, and as shown in fig. 4, the method includes:
step 401, obtain a first signal quality of a current serving cell and a second signal quality of an adjacent non-serving cell.
Step 402, determining whether the first signal quality is higher than the second signal quality, if so, executing step 403, otherwise, executing step 410.
And step 403, determining a signal strength offset value based on the second signal quality.
Optionally, determining a signal strength offset value based on the second signal quality includes: acquiring a preset functional relation between signal quality and signal strength bias; determining a signal strength bias value corresponding to the second signal quality based on the functional relationship with the second signal quality; wherein the signal strength offset value is inversely related to the second signal quality. Optionally, determining a signal strength offset value based on the second signal quality includes: acquiring a preset corresponding relation table between signal quality and signal strength bias; and determining a signal strength offset value corresponding to the second signal quality according to the second signal quality and the corresponding relation table between the signal quality and the signal strength offset.
Step 404, obtaining a first signal strength of the neighboring non-serving cell and a second signal strength of the current serving cell.
Step 405, determine whether the first signal strength is greater than the second signal strength, if yes, execute step 406, otherwise, execute step 410.
Step 406, determining the target signal strength according to the first signal strength and the signal strength offset value.
Wherein the target signal strength is a difference between the first signal strength and the signal strength offset value;
step 407, taking the target signal strength as the signal strength of the adjacent non-serving cell in the measurement report, and reporting the measurement report to the network side.
It can be understood that, when the first signal strength of the neighboring non-serving cell is greater than the second signal strength of the current serving cell, if the first signal strength is directly reported to the network side as the signal strength of the neighboring non-serving cell in the measurement report, because the first signal strength is greater than the second signal strength, the network side may instruct the mobile terminal to switch the serving cell to the neighboring non-serving cell with poor signal quality, which may easily cause poor call quality of the mobile terminal and may easily cause a call drop phenomenon. Therefore, the target signal strength can be generated after the first signal strength is reduced by the signal strength offset value, and the target signal strength is reported to the network side as the signal strength of the adjacent non-serving cell in the measurement report, so that the probability that the serving cell is switched to the cell with poor signal quality by the mobile terminal can be effectively reduced, and the call voice quality of the mobile terminal can be effectively ensured.
