UE is during establishing connection with base station in the prior art, if UE fails in current time access base station, UE
It can continue to initiate access request to base station in subsequent time；And during waiting to be accessed, UE occupies channel resource always；
To solve the above problems, the embodiment of the present invention provides a kind of cut-in method, concrete implementation process is as follows:
Embodiment one
The embodiment of the present invention provides a kind of cut-in method, includes: as shown in Figure 2
S101, UE receive the RSRP value that base station is sent.
Optionally, this method as shown in Figure 3 and Figure 6 further include:
The access customer number L in each covering grade corresponding unit time that S104, reception base station are senti、NPRACH
Cycle TiWith subcarrier number Ni。
It should be noted that in actual application, it is assumed that CE Level i includes 3 covering grades, respectively CE
Level 0, CE Level 1 and CE Level 2 (i ∈ [0,1,2]), then connecing in each covering grade corresponding unit time
Access customer number Li, NPRACH cycle Ti(unit are as follows: second) and subcarrier number Ni, comprising:
Access customer number L when i=0, in the 0 lower unit time of CE Level0, NPRACH cycle T0And subcarrier number
N0。
Access customer number L when i=1, in the 1 lower unit time of CE Level1, NPRACH cycle T1And subcarrier number
N1。
Access customer number L when i=2, in the 2 lower unit time of CE Level2, NPRACH cycle T2And subcarrier number
N2。
S105, according to the access customer number L in each covering grade corresponding unit timei, NPRACH cycle TiWith sub- load
Wave number Ni, determine the corresponding access controlling elements F of each covering gradei。
S106, according to the corresponding NPRACH cycle T of each covering gradei, determine delay access control limitation time Di。
It should be noted that in actual application, when corresponding according to each covering grade that base station the is sent unit of UE
Interior access customer number Li, NPRACH cycle TiWith subcarrier number NiWhether can more accurately determine can occur
Access request is to base station.
Optionally, this method as shown in Figure 4 and Figure 6 further include:
S107, the corresponding access controlling elements F of each covering grade that base station is sent is receivediControl limitation is accessed with delay
Time Di；Wherein, controlling elements F is accessediIt is base station according to the access customer number in each covering grade corresponding unit time
Li, NPRACH cycle TiWith subcarrier number NiDetermining, delay access control limitation time DiIt is base station according to each covering etc.
The corresponding NPRACH cycle T of gradeiDetermining.
It should be noted that in actual application, access controlling elements F that UE is sent according to base stationiIt is accessed with delay
Control limitation time DiDiscriminate whether to occur access request to base station, without carrying out additional calculating, so that UE is more
Power saving.
It should be noted that assuming that CE Level i includes 3 covering grades, respectively CE Level0, CE Level 1
With CE Level 2 (i ∈ [0,1,2]), the first RSRP threshold value is Threshold1, and the 2nd RSRP threshold value is Threshold2；UE
From the access control parameter obtained in base station broadcast message under NPRACH configuration message and different covering grades: accessing controlling elements
FiLimitation time D is controlled with accessi。
UE is according to the measurement (RSRP information) to base station down channel and the knot compared with the threshold parameter of base station broadcast
Fruit adjudicates the covering grade CE level oneself being presently in.
If when RSRP≤Threshold2 of UE measurement, CE level=2 locating for UE.
If when Threshold2 < RSRP≤Threshold1 of UE measurement, CE level=1 locating for UE.
If when the RSRP > Threshold1 of UE measurement, CE level=0 locating for UE.
S102, UE determine the covering grade being presently according to RSRP value.
Optionally, UE determines the covering grade being presently according to RSRP value, comprising: UE determines that RSRP value is greater than first
When RSRP threshold value, determine that the covering grade being presently in is the first covering grade；UE determines that RSRP value is greater than the 2nd RSRP threshold value,
And when RSRP value is less than or equal to the first RSRP threshold value, determine that the covering grade being presently in is the second covering grade；UE is true
Determine RSRP value to be less than or when the 2nd RSRP threshold value of grade, determine that the covering grade being presently in is third covering grade；Wherein,
Two RSRP threshold values are less than the first RSRP threshold value.
UE differentiates whether the uniform random number rand generated at random is less than the corresponding access controlling elements of covering grade
Fi。
S103, UE determine that the uniform random number rand generated at random is less than the corresponding access controlling elements of covering grade
FiWhen, access request is sent to base station；Wherein, uniform random number is greater than 0 and less than 1,LiExpression is covered
Access customer number in the unit time of lid grade, TiIndicate the NPRACH period of covering grade, NiIndicate that the son of covering grade carries
Wave number.
Optionally, this method as shown in Figure 5 and Figure 6 further include:
S108, UE determine that uniform random number rand is greater than or equal to access controlling elements FiWhen, delay access control
Limit time DiAfterwards, access request is sent to base station；Wherein, Di=K × Ti, K is positive integer.
It should be noted that UE after S108, when sending access request to base station again, needs to generate again and uniformly divide
Cloth random number rand, and differentiate whether the uniform random number rand generated at random is less than the corresponding access control of covering grade
Factor Fi；In actual application, when UE sends access request to base station every time, need to generate at random equal between one 0~1
Even distribution random numbers rand decides whether energy according to the locating corresponding access controlling elements of covering grade i and covering grade i
(after needing to obtain the covering grade that UE is presently according to S101 and S102 again, differentiation generates uniform at random for enough accesses
Whether distribution random numbers rand is less than the corresponding access controlling elements F of covering gradei)。
Wherein, as rand < Fi, UE is had access to.
As rand > Fi, UE stops sending access request to base station, and sends again to base station after postponing a period of time
Access request, delay time Di。
Due to 0≤rand≤1, and each covering grade i corresponds to FiSize depend on the current operating parameter in base station；Cause
This, UE can discriminate whether to be included in request to base station transmission, to improve channel resource according to the actual operation parameters of base station
Utilization rate；Simultaneously when channel resource is less, other users can still obtain channel resource, ensure that the experience of user；Fortune
Row parameter includes at least: the access customer number L in the unit timei, NPRACH cycle TiWith subcarrier number NiAny one of.
By above scheme it is found that UE is during establishing connection with base station in the prior art, if UE connects at current time
Enter base station failure, then UE can continue to initiate access request to base station in subsequent time；And during waiting to be accessed, UE is always
Occupy channel resource；For this purpose, the cut-in method that embodiment through the invention provides, when UE determines that is generated at random uniformly divides
When cloth random number is less than covering grade corresponding access controlling elements, to base station transmission access request；To reduce with for the moment
The quantity for initiating the UE of access request is carved, that is, the quantity of UE to be accessed such as reduces, to improve the utilization of channel resource
Rate；Solve the problems, such as that the utilization rate of channel resource in the prior art is lower.
