N is the integer more than or equal to 1；
When the value of the number of times parameter is less than preset value, the channel quality does not meet decoding condition.
Gathering way for the number of times parameter can be more than, less than or equal to the reduction speed of the number of times parameter, i.e. institute
Stating m can be more than, less than or equal to n.
Preferably, the m is less than n, so that when channel quality is poor, subsequent treatment can be carried out as early as possible.Such as：When
1st, 8 and 12 CRCs are correct, and the 2nd ~ 7,9 ~ 11 and 13 ~ 17 CRC mistakes, and the m is 1,
The n is 2, and the preset value is 0, when the fixed value is 24, first sets number of times parameter t initial value as 24；Due to
One CRC is correct, and number of times parameter t should carry out Jia 1 operating, but be due to be changed into 25 after number of times parameter t plus 1
More than 24, therefore now, number of times parameter t value is still 24；Due to second circulation redundancy check code mistake, therefore number of times parameter t
Need to subtract 2 and be changed into 22；Due to the 3rd CRC mistake, therefore number of times parameter t needs to subtract 2 and is changed into 20；……..；
Due to the 7th CRC mistake, therefore number of times parameter t needs to subtract 2 and is changed into 12；Due to the 8th cyclic redundancy school
Test code correct, therefore number of times parameter t needs Jia 1 to be changed into 13；Due to the 9th CRC mistake, therefore number of times parameter
T, which needs to subtract 2, is changed into 11；Due to the tenth CRC mistake, therefore number of times parameter t needs to subtract 2 and is changed into 9；Due to
11 CRC mistakes, therefore number of times parameter t needs to subtract 7；Because the 12nd CRC is correct,
Therefore number of times parameter t needs Jia 1 to be changed into 8；Due to the 13rd CRC mistake, therefore number of times parameter t needs to subtract 2
It is changed into 6；……；Due to the 16th CRC mistake, therefore number of times parameter t needs to subtract 2 and is changed into 0；Due to the tenth
Seven CRC mistakes, therefore number of times parameter t needs to subtract 2 and is changed into -2, now -2 are less than preset value 0, therefore described
Channel quality does not meet decoding condition, it is necessary to continue executing with step S5.
In second specific example, judge whether the channel quality meets decoding condition and include：When the circulation is superfluous
When the number of the continuous mistake of remaining check code is more than setting value, the channel quality does not meet decoding condition.Described in the present embodiment
The span of setting value can be more than or equal to 3, if the continuous wrong number of that is, described CRC be more than or
Equal to 3, then the channel quality does not meet decoding condition.
In the 3rd specific example, judge whether the channel quality meets decoding condition and include：When the circulation is superfluous
When the number of remaining check code cumulative error is more than setting value, the channel quality does not meet decoding condition.Described in the present embodiment
The span of setting value can be more than or equal to 3, as long as the number of that is, described CRC cumulative error be more than or
Equal to 3, then the channel quality does not meet decoding condition.
The span of above-mentioned second specific example and the setting value in the 3rd specific example can be different.
When the channel quality does not meet decoding condition, step S5 is continued executing with, the reference signal is adjusted and receives work(
Rate or Reference Signal Received Quality report value.
The present embodiment can be when the channel quality meet decoding condition, by the Reference Signal Received Power or ginseng
Examine signal receiving quality and be adjusted to corresponding minimum value.Specifically, the corresponding minimum value of the Reference Signal Received Power can be with
For -150dBm；The corresponding minimum value of the Reference Signal Received Quality can be -120dB.
Such as：It is -100dBm that obtained RSRP is calculated in step S2, and current channel matter is learnt by step S3 and step S4
Amount does not meet decoding condition, therefore the RSRP that in step s 5 will obtain calculating is adjusted to -150dBm by -100dBm.
And for example：It is -95dB that obtained RSRQ is calculated in step S2, and current channel matter is learnt by step S3 and step S4
Amount does not meet decoding condition, therefore the RSRQ that in step s 5 will obtain calculating is adjusted to -120dB by -95dB.
In addition, the present embodiment by the Reference Signal Received Power or Reference Signal Received Quality be adjusted to it is corresponding most
After small value, it can also include：The Reference Signal Received Power or Reference Signal Received Quality after adjustment is sent to nothing
Line Resource Control protocols layer, the radio resource control layer carries out cell switching or system switching or falls net processing.
Specifically, being sent to radio resource control layer includes the RSRP after adjustment or the RSRQ after adjustment measurement report, due to
RSRP or RSRQ numerical value is smaller in measurement report, therefore radio resource control layer can make to be currently at and can not realize number
Cell switching is carried out according to the LTE service terminals in the serving cell of decoding or system switches or fallen net processing, so that LTE is moved
Terminal may be in the relatively good serving cell can realize data decoding of channel service quality in IDEL states, finally will not
Occur paging without situation about decode in time, improve service success rate.
Further, due in a paging cycle only by a sub- frame decoding PBCH data, a therefore paging
