Based on above-mentioned 100 hardware configuration of mobile terminal and communications network system, each embodiment of the method for the present invention is proposed.
It is a kind of step process of the cell method of adjustment of mobile terminal provided in an embodiment of the present invention refering to Fig. 3, Fig. 3
Figure, as shown in Figure 3, which comprises
Step S301, in the case where multiple alien frequencies networks meet high priority reselection criteria, quality is selected according to cell
Value Squal is ranked up multiple alien frequencies networks, and Squal is selected to sort highest cell as first community and Squal sequence
Secondary high cell is as second community.
In the present embodiment, high priority reselection criteria (Cell Reselection to a higher-priority
Inter-RAT/Inter-Frequency cell) content include: as SIB3 (SystemInformationBlockType3)
There is provided current service cell gravity treatment to the different system cell of low priority threshold value in the case where, if Target cell is 3G network
Or 4G network, in a TreselectionRAT time interval, Squal > ThreshX, HighQ, wherein
TreselectionRAT is cell reselection time interval；Squal indicates cell selection quality value, and ThreshX, HighQ indicate high
The signal quality threshold of priority frequency X；
Squal=Qqualmeas- (Qqualmin+Qqualminoffset), wherein Qqualmeas indicates cell quality
Measured value, Qqualmin indicate minimum level of quality value, and Qqualminoffset indicates the deviant relative to Qqualmin.
If Target cell is GSM network, in a TreselectionRAT time interval, Srxlev > ThreshX,
HighP, wherein Srxlev indicates that cell selection reception level value, ThreshX, HighP indicate the signal of high priority frequency X
Intensity threshold；
Mobile terminal resides in current service cell 1 second or more.
If according to high priority reselection criteria it is found that alien frequencies high priority gravity treatment is provided in system message
ThreshServingLowQ, as long as then within the TreselectionRAT time Squal > ThreshX, HighQ, can meet
Alien frequencies reselection conditions.
If there is multiple alien frequencies networks meet reselection conditions, then multiple alien frequencies networks are ranked up according to Squal, are selected
Squal sorts the highest cell cell high as first community and Squal sequence time as second community.
Step S302, obtain respectively the first community the first signal quality RSRQ and the second community second
RSRQ, judges whether the first RSRQ and the 2nd RSRQ are all larger than preset threshold.
In the present embodiment, RSRQ indicates signal quality, and full name in English is Reference Signal Receiving
Quality.The preset threshold can be customized numerical value, or the numerical value being rule of thumb arranged, for example, described default
Threshold value can be set to -15.For example, if the configuration parameter of first community includes: cell 28, earfcn:38950:RSRP:-
115.00；RSRQ:13.56；Srxlev:3；Squal:5；The configuration parameter of second community includes: cell 55, earfcn:
38400:RSRP:-93.63；RSRQ；-14.75；Srxlev:26；Squal:4.The RSRQ of first community is -13.56, and second is small
The RSRQ in area is all larger than -15 for -14.75.
Step 303, in the case where the first RSRQ and the 2nd RSRQ are all larger than preset threshold, obtain institute respectively
State the first signal strength RSRP of first community and the 2nd RSRP of the second community.
In the present embodiment, RSRP indicates signal strength, and full name is Reference Signal Receiving Power.
When the first RSRQ and the 2nd RSRQ are all larger than preset threshold, first community and the may insure by preset threshold
The signal quality of two cells in range relatively, be not in a cell signal quality it is too small or another is small
The too strong situation of the signal quality in area.For example, if the configuration parameter of first community includes: cell 28, earfcn:
38950；RSRP:-115.00；RSRQ:13.56；Srxlev:3；Squal:5；The configuration parameter of second community includes: cell
55, earfcn:38400:RSRP:-93.63；RSRQ；-14.75；Srxlev:26；Squal:4.The RSRP of first community be-
115.00, the RSRP of second community is -93.63.
Step 304 determines first weighted value of the first RSRQ relative to the 2nd RSRQ, determines the 2nd RSRP phase
For the second weighted value of the first RSRP.
It is understood that there are many modes of the first weighted value of calculating, for example, can be by the first RSRQ divided by second
The quotient of RSRQ as the first weighted value, can also using the difference of the first RSRQ and the 2nd RSRQ divided by the quotient of the 2nd RSRQ as first
Weighted value, herein with no restrictions.There are many modes for calculating the second weighted value, for example, can be by the first RSRP divided by second
The quotient of RSRP as ER weighted value, can also using the difference of the 2nd RSRP and the first RSRP divided by the quotient of the 2nd RSRP as second
Weighted value, herein with no restrictions.
Step S305, in the case where second weighted value is greater than first weighted value, the second community is selected
As re-selecting cell.
When second weighted value is greater than first weighted value, that is, illustrate the network signal quality of second community than the
The network signal of one cell is strong, even if the Squal of first community is greater than the Squal of second community, also using second community as weight
Cell is selected, may insure to avoid dropping to 2G or 3G network in the network quality for carrying out cell reselection connection procedure in this way.
The cell method of adjustment of mobile terminal proposed by the invention meets high priority gravity treatment mark in multiple alien frequencies networks
In the case where standard, multiple alien frequencies networks are ranked up according to cell selection quality value Squal, select Squal sequence highest
The cell cell high as first community and Squal sequence time is as second community；The first of the first community is obtained respectively
The 2nd RSRQ of signal quality RSRQ and the second community judge whether the first RSRQ and the 2nd RSRQ is big
In preset threshold；In the case where the first RSRQ and the 2nd RSRQ are all larger than preset threshold, described the is obtained respectively
First signal strength RSRP of one cell and the 2nd RSRP of the second community；Determine the first RSRQ relative to described second
The first weighted value of RSRQ determines second weighted value of the 2nd RSRP relative to the first RSRP；In second power
In the case that weight values are greater than first weighted value, select the second community as re-selecting cell.In this way, mobile terminal can be with
The stronger network of selection signal quality carries out network reselection from multiple alien frequencies networks for meeting alien frequencies high priority reselection criteria
Connection procedure, it is ensured that communication quality.
It is the step process of the cell method of adjustment of another mobile terminal provided in an embodiment of the present invention refering to Fig. 4, Fig. 4
Figure, as shown in Figure 4, which comprises
Step S401, in the case where multiple alien frequencies networks meet high priority reselection criteria, quality is selected according to cell
Value Squal is ranked up multiple alien frequencies networks, and Squal is selected to sort highest cell as first community and Squal sequence
Secondary high cell is as second community.
In the present embodiment, high priority reselection criteria (Cell Reselection to a higher-priority
Inter-RAT/Inter-Frequency cell) include the following contents: work as SIB3
(SystemInformationBlockType3) threshold value of the offer current service cell gravity treatment to the different system cell of low priority
In the case where, if Target cell is 3G network or 4G network, in a TreselectionRAT time interval, Squal >
ThreshX, HighQ, wherein TreselectionRAT is cell reselection time interval；Squal indicates cell selection quality value,
The signal quality threshold of ThreshX, HighQ expression high priority frequency X；
