Mutually.The alien frequencies reselection information includes system information block SIB3 message or SIB5 message.
The system information block that Cell can provide operator's white list and issue makes HPUE reside in its MPS process model
In enclosing, HPUE, which can be configured under high power PC2 grade, carries out power emission, and assistant base station reduces coverage area, reduces total
Network signaling overhead.Cell and base station side configure identical operator's white list, are such as HPUE by the base station of which operator
HPUE service is provided, different operators white list code is different.
It the described method comprises the following steps.
Step S11, for any one Cell of base station covering, the HPUE obtained in the Cell coverage area is reported
Minimum base station side signal receiving strength.
Step S12, according to the minimum base station side signal receiving strength and the HPUE with as defined in power grade 2 most
Power calculation when big output power PC2 work obtains the first signal receiving strength.
Where it is assumed that the Tdd sub-frame configuration of HPUE is constant, adjacent C ell is configured to 00,01 or 10 at SIB5, power
Peak power output PC2 as defined in grade 2 is 26dbm.After P-max increases to 26dbm, it is only necessary in the SIB3/ of base station side
Signal receiving strength (Minimum required Rx level in the cell in minimum basis station side is adjusted under SIB5 message
(dBm), Qrxlevmin), can regulation HPUE reside under which cell.
For example, if the Cell1 minimum base station side signal receiving strength that HPUE is reported is -85dbm/epre, then, the first letter
Number receiving intensity is equal to the minimum base station side signal that peak power output 26dbm as defined in power grade 2 and HPUE are reported and receives
The difference DELTA dB of intensity -85dbm/epre, Δ dB=26dbm- (- 85dbm/epre)=111db.Δ dB can be defined as base station
The reception intensity values (Cell selection Rx level value (dB), Srxlev) of cell selection.
Step S13, power meter when being worked according to the receiving intensity and the HPUE that are set for the Cell with PC2
Calculation obtains second signal receiving intensity.
It can be set by following steps for the receiving intensity of the Cell：In the alien frequencies reselection information of the base station
The signal receiving strength for adjusting each Cell of the base station covering, to obtain the receiving intensity for each Cell setting.Such as,
It can be directed to comprising field q-QualMin-r10 parameter value by adjusting the parameter value under SIB3/SIB5 message
The receiving intensity of Cell setting.
For example, it is assumed that receiving intensity set for Cell1 is -80dbm, then second signal receiving intensity is equal to power
The difference DELTA dB, Δ dB=of peak power output 26dbm as defined in grade 2 and the receiving intensity -80dbm for Cell1 setting
26dbm- (- 80dbm/epre)=106db.
Step S14, judges whether first signal receiving strength is greater than the second signal receiving intensity, if described
One signal receiving strength is greater than the second signal receiving intensity, thens follow the steps S15.If first signal receiving strength is small
In or equal to the second signal receiving intensity, S16 is thened follow the steps.
Step S15 refuses the HPUE and resides under the Cell.
Step S16 allows the HPUE to reside under the Cell.
For example, being directed to Cell1, the first signal receiving strength 111 is greater than second signal receiving intensity 106, thus, refusal
HPUE is resided under Cell1, and Cell1 is not used to provide HPUE service for HPUE.
In another example, it is assumed that the neighboring community each other Cell1 and Cell2, peak power output PC2 as defined in power grade 2 are
26dbm.As -100dbm/epre, the Cell2 minimum base station side signal that HPUE is reported receives the receiving intensity set for Cell2
Intensity be -85dbm/epre, then, the first signal receiving strength be equal to power grade 2 as defined in peak power output 26dbm with
The difference DELTA dB, Δ dB=26dbm- (- 85bm/ for the minimum base station side signal receiving strength -85dbm/epre that HPUE is reported
Epre)=111db.Second signal receiving intensity is equal to peak power output 26dbm as defined in power grade 2 and is directed to Cell1
The difference DELTA dB of the receiving intensity -100dbm of setting, Δ dB=26dbm- (- 100dbm/epre)=126db.Comparison is it is found that needle
To Cell2, the first signal receiving strength 111 is less than second signal receiving intensity 126, thus, allow HPUE to reside in Cell2
Under, use Cell2 to provide HPUE service for HPUE.
Please refer to Fig. 3, if two adjacent areas all in the presence of, as covered there are HPUE for the base station
More than two Cell have reported minimum base station side signal receiving strength, and the more than two minimum basis reported according to the HPUE respectively
The result that side signal receiving strength is analyzed of standing is that the HPUE can be resided under more than two Cell, it is possible to hold
Row following steps.
Step S21, adjustment can provide the two of HPUE service in the alien frequencies reselection information of the base station for the HPUE
The receiving intensity of a above Cell.
Step S22 determines what the HPUE was finally resident according to receiving intensity adjusted, for each Cell setting
Cell。
For example, according to the reference of the HPUE more than two Cell that can provide HPUE service for the HPUE reported
Signal reception power (Reference Signal Receiving Power, RSRP), adjustment can provide for the HPUE
The receiving intensity of more than two Cell of HPUE service.Such as more than two Cell reference signal reported respectively is connect according to HPUE
It receives power (Reference Signal Receiving Power, RSRP), to cooperate with the minimum basis for determining one of Cell
Stand side signal receiving strength Qrxlevmin, and then allows HPUE is selective to reside under the cell.
It, can be with by adjusting the Qrxlevmin under corresponding Cell since the RSRP value that HPUE reports adjacent C ell is different
Selectivity allows HPUE to reside in offer HPUE service under the Cell.According to actual needs, it can choose the preferable Cell of RSRP
Service is provided, RSRP poor Cell is accordingly also can choose and service is provided.
In order to more clearly illustrate the realization principle of the disclosure, now by taking following scenes as an example, to the realization stream of the disclosure
Journey is illustrated.
Base station side and HPUE are configured with consistent white list, detect that user terminal supports HPUE, function under SIB3 and SIB5
Peak power output PC2 as defined in rate grade 2 is 26dbm, the SIB3 message eigh cell config=10 of adjacent cell configuration.
Assuming that it is -89dbm that HPUE, which reports the Reference Signal Received Power of current base station cell, HPUE is resident small herein at this time
Under area, receiving power to the reference signal that adjacent cell base station reports is -105dbm.If under current base station cell under SIB3 message
Q-QualMin-r10 field is -85dbm, and the q-QualMin-r10 field of corresponding adjacent cell is -100dbm, current area
Srxlev1, which is calculated by the following formula, to be obtained：
Srxlev1=Δ dB=26- (- 85)=111dbm.
Srxlev2=Δ dB=26- (- 100)=126dbm of adjacent cell, HPUE only resides in current base station cell at this time
Without following network switching to reside under the strong cell of signal to adjacent cell namely HPUE.If being switched to adjacent cell to it
I.e. under the weaker cell of signal, it is only necessary to improve the value of current area q-QualMin-r10 field>- 85dbm reduces adjacent small
Area q-QualMin-r10<- 100dbm, then HPUE terminal can reside under the weaker adjacent area of signal.Letter is resided in it
