Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.

Referring to fig. 3, fig. 3 is a flowchart illustrating a cell adjustment method of a mobile terminal according to an embodiment of the present invention, and as shown in fig. 3, the method includes:

step S301, under the condition that the plurality of pilot frequency networks meet the high-priority reselection standard, sorting the plurality of pilot frequency networks according to the cell selection quality value Squal, and selecting the cell with the highest Squal sorting order as a first cell and the cell with the highest Squal sorting order as a second cell.

In this embodiment, the contents of the high priority Reselection criteria (Cell Reselection to a high priority Inter-RAT/Inter-Frequency Cell) include: under the condition that SIB3(SystemInformationBlockType3) provides a threshold value for reselecting the current serving cell to a low-priority heterogeneous system cell, if the target cell is a 3G network or a 4G network, within a TreselectionRAT time interval, Squal > ThreshX, HighQ, wherein TreselectionRAT is the cell reselection time interval; squal represents a cell selection quality value, ThreshX, HighQ represents a signal quality threshold for high priority frequency X;

qqualmeas- (Qqualmin + Qqualmin offset), where Qqualmeas represents a cell quality measurement, Qqualmin represents a minimum quality level value, and Qqualmin offset represents an offset value relative to Qqualmin.

If the target cell is a GSM network, Srxlev > ThreshX, HighP within a TreselecterRAT time interval, wherein Srxlev represents a cell selection reception level value, ThreshX, HighP represents a signal strength threshold of a high priority frequency X;

the mobile terminal resides in the current serving cell for more than 1 second.

According to the high-priority reselection standard, if threshServingLowQ is set in the system message, the pilot frequency reselection condition can be satisfied as long as Squal > ThreshX and highQ in the TreselecterRAT time.

And if a plurality of pilot frequency networks meet the reselection condition, sequencing the pilot frequency networks according to the Squal, and selecting the cell with the highest Squal sequencing as a first cell and the cell with the highest Squal sequencing order as a second cell.

Step S302, respectively obtaining a first signal quality RSRQ of the first cell and a second RSRQ of the second cell, and judging whether the first RSRQ and the second RSRQ are both larger than a preset threshold value.

In this embodiment, RSRQ represents Signal Quality, and is generally referred to as Reference Signal Receiving Quality. The preset threshold may be a custom value or an empirically set value, for example, the preset threshold may be set to-15. For example, if the configuration parameters of the first cell include: cell 28, earfcn: 38950: RSRP: -115.00; RSRQ: 13.56; srxlev: 3; squal: 5; the configuration parameters of the second cell include: cell 55, earfcn: 38400: RSRP: -93.63; RSRQ; -14.75; srxlev: 26; squal: 4. the RSRQ of the first cell is-13.56, and the RSRQ of the second cell is-14.75 and is larger than-15.

Step 303, when both the first RSRQ and the second RSRQ are greater than a preset threshold, respectively obtaining a first signal strength RSRP of the first cell and a second RSRP of the second cell.

In this embodiment, RSRP represents Signal strength and is called Reference Signal Receiving Power. When the first RSRQ and the second RSRQ are both larger than a preset threshold, the signal quality of the first cell and the signal quality of the second cell can be ensured to be in a relatively close range through the preset threshold, and the situation that the signal quality of one cell is too small or the signal quality of the other cell is too strong cannot occur. For example, if the configuration parameters of the first cell include: cell 28, earfcn: 38950, respectively; RSRP: -115.00; RSRQ: 13.56; srxlev: 3; squal: 5; the configuration parameters of the second cell include: cell 55, earfcn: 38400: RSRP: -93.63; RSRQ; -14.75; srxlev: 26; squal: 4. the RSRP of the first cell is-115.00 and the RSRP of the second cell is-93.63.

Step 304, determining a first weight value of the first RSRQ relative to the second RSRQ, and determining a second weight value of the second RSRP relative to the first RSRP.

It is to be understood that there are various ways to calculate the first weight value, for example, a quotient obtained by dividing the first RSRQ by the second RSRQ may be used as the first weight value, and a quotient obtained by dividing a difference between the first RSRQ and the second RSRQ by the second RSRQ may be used as the first weight value, which is not limited herein. For example, a quotient obtained by dividing the first RSRP by the second RSRP may be used as the first ER weight value, and a quotient obtained by dividing a difference between the second RSRP and the first RSRP by the second RSRP may be used as the second weight value, which is not limited herein.

Step S305, when the second weight value is greater than the first weight value, selecting the second cell as a reselected cell.

When the second weight value is greater than the first weight value, that is, the network signal quality of the second cell is higher than that of the first cell, even if the Squal of the first cell is greater than that of the second cell, the second cell is used as a reselected cell, so that the network quality in the process of cell reselection connection can be ensured, and the situation that the network quality falls into a 2G or 3G network is avoided.

The cell adjusting method of the mobile terminal provided by the invention sorts a plurality of pilot frequency networks according to the cell selection quality value Squal under the condition that the pilot frequency networks meet the high-priority reselection standard, and selects the cell with the highest Squal sorting as a first cell and the cell with the highest Squal sorting order as a second cell; respectively acquiring first signal quality RSRQ of the first cell and second RSRQ of the second cell, and judging whether the first RSRQ and the second RSRQ are both larger than a preset threshold value; respectively acquiring a first signal strength RSRP of the first cell and a second RSRP of the second cell under the condition that the first RSRQ and the second RSRQ are both larger than a preset threshold value; determining a first weight value of a first RSRQ relative to the second RSRQ, determining a second weight value of the second RSRP relative to the first RSRP; selecting the second cell as a reselecting cell if the second weight value is greater than the first weight value. Therefore, the mobile terminal can select a network with stronger signal quality from a plurality of pilot frequency networks meeting the pilot frequency high-priority reselection standard to perform a network reselection connection process, so as to ensure the communication quality.

Referring to fig. 4, fig. 4 is a flowchart illustrating steps of another method for adjusting a cell of a mobile terminal according to an embodiment of the present invention, as shown in fig. 4, the method includes:

step S401, under the condition that the plurality of pilot frequency networks meet the high-priority reselection standard, sorting the plurality of pilot frequency networks according to the cell selection quality value Squal, and selecting the cell with the highest Squal sorting order as a first cell and the cell with the highest Squal sorting order as a second cell.

In the present embodiment, the Cell Reselection to a high priority Inter-RAT/Inter-Frequency Cell (Cell Reselection to a high priority Inter-RAT/Inter-Frequency Cell) includes the following: under the condition that SIB3(SystemInformationBlockType3) provides a threshold value for reselecting the current serving cell to a low-priority heterogeneous system cell, if the target cell is a 3G network or a 4G network, within a TreselectionRAT time interval, Squal > ThreshX, HighQ, wherein TreselectionRAT is the cell reselection time interval; squal represents a cell selection quality value, ThreshX, HighQ represents a signal quality threshold for high priority frequency X;

the mobile terminal resides in the current serving cell for more than 1 second.

In this way, the cells with the highest Squal can be quickly selected as the first cell and the next highest Squal can be quickly selected as the second cell, sorted from high to low.

Step S402, respectively obtaining a first signal quality RSRQ of the first cell and a second RSRQ of the second cell, and judging whether the first RSRQ and the second RSRQ are both larger than a preset threshold value.

The preset threshold may be a custom value or an empirically set value, for example, the preset threshold may be set to-15. For example, if the configuration parameters of the first cell include: cell 28, earfcn: 38950: RSRP: -115.00; RSRQ: 13.56; srxlev: 3; squal: 5; the configuration parameters of the second cell include: cell 55, earfcn: 38400: RSRP: -93.63; RSRQ; -14.75; srxlev: 26; squal: 4. the RSRQ of the first cell is-13.56, and the RSRQ of the second cell is-14.75 and is larger than-15.

Optionally, the step S402 of respectively obtaining the first signal quality RSRQ of the first cell and the second RSRQ of the second cell includes:

the first RSRQ may be determined from the aforementioned first measurement report according to a resolution rule of the measurement report; determining the second RSRQ from the aforementioned second measurement report.

Step 403, when both the first RSRQ and the second RSRQ are greater than a preset threshold, respectively obtaining a first signal strength RSRP of the first cell and a second RSRP of the second cell.

In this embodiment, when both the first RSRQ and the second RSRQ are greater than the preset threshold, the preset threshold may ensure that the signal qualities of the first cell and the second cell are in a relatively close range, and a situation that the signal quality of one cell is too low or the signal quality of another cell is too high may not occur. For example, if the configuration parameters of the first cell include: cell 28, earfcn: 38950, respectively; RSRP: -115.00; RSRQ: 13.56; srxlev: 3; squal: 5; the configuration parameters of the second cell include: cell 55, earfcn: 38400: RSRP: -93.63; RSRQ; -14.75; srxlev: 26; squal: 4. the RSRP of the first cell is-115.00 and the RSRP of the second cell is-93.63.

In this embodiment, the first RSRP may be determined from the aforementioned first measurement report according to a resolution rule of the measurement report; determining the second RSRP from the aforementioned second measurement report.

Step 404, determining a first weight value of the first RSRQ relative to the second RSRQ, and determining a second weight value of the second RSRP relative to the first RSRP.

In this way, a more accurate first weight value can be obtained quickly.

In this way, the more accurate second weight value can be obtained quickly.

Step S405, when the second weight value is greater than the first weight value, selecting the second cell as a reselected cell.

Optionally, the step S405 may include the following steps:

Thus, when the second weight value is greater than the product of the first weight value and N, it can be shown that the signal quality of the second cell is much greater than that of the first cell, and the second cell is selected as the reselected cell, which can ensure the signal quality of the reselected cell and improve the cell reselection effect of the mobile terminal.

Step S406, initiating a tracking area update TAU request to the second cell, and establishing a communication connection with the second cell.

In this embodiment, a communication connection may be established with the second cell by sending a TAU request, for example, the TAU request may be OTA LOG01:39:46.152 LTE NAS EMM plane otautgo messaging exchange area update request Msg 2. After sending the TAU request, an RRC connection request may also be sent, for example, the RRC connection request may be OTA LOG01:39:46.152UL _ CCCH/RRCConnectionRequestRadio Bearer ID:0, Freq:38950, SFN: 02; OTA LOG01:39: 57.080LTE NAS EMM plan OTA outlying MessageTracking area update request Msg 2.

Therefore, through the TAU request, the communication connection can be established with the second cell, the poor cell can be avoided being reselected when the terminal is in a standby state, networks such as 2G or 3G are avoided, and the mobile terminal is ensured to be always in a communication state with better signal quality.
