Description
Technical field
The present invention relates to wireless communication technology, particularly relate to a kind of quick paging channel (QuickPagingChannel, be called for short QPCH) adaptive power control method and realize the base station controller of QPCH optimal energy allocation.
Background technology
In the cdma 2000 system, paging channel can take periodic ranging mode, i.e. terminal periodic ground and system message on discontinuous monitoring seek channel and beep-page message, when non-be defined as paging cycle when, terminal closes receiver, thus decreases energy ezpenditure.
In order to the battery consumption of more effective saving travelling carriage, CDMA2000 agreement adds an optional attribute: the channel relevant to paging--QPCH.Terminal under base station uses QPCH notice to be in the slotted mode of idle condition: whether they should receive the Paging Channel Slot being about to arrive.One to one, just QPCH time slot starts than the paging time-slot in paging channel paging time-slot in the QPCH time slot that each mobile assignment obtains and paging channel in advance, has time enough to wake up the work of restarting of coming from sleep state to make travelling carriage.
QPCH only sends two category informations, one is paging indicating bit (PagingIndicator is called for short PI), and another is configuration change indicating bit (ConfigurationChangeIndicator, be called for short CCI), and their every 80ms repeat twice.If if travelling carriage does not support that QPCH operates or base station parameter QPCH_SUPPORTEDS=0, then travelling carriage is by each time slot monitoring seek channel in its correspondence.If if travelling carriage supports quick paging channel operation and QPCH_SUPPORTEDS=1, for the travelling carriage being in idle condition, when it is in slotted mode, check the paging indicating bit that QPCH specifies, perform and operate as follows:
(1) if travelling carriage finds that first PI is for " 0 ", travelling carriage does not need the PI detecting other, enters sleep state;
(2) if travelling carriage finds that first PI is " 1 " or Erasure, travelling carriage continues judgement second PI;
(3) if travelling carriage judges that second PI is as " 0 ", enters sleep state, otherwise the time slot that travelling carriage will go monitoring seek channel corresponding.
During idle holding state, travelling carriage only monitors quick paging channel, owing to only needing to receive and demodulate little information, thus just reaches the object of power saving.
In addition, as parameter slot cycle index (SlotCycleIndex, be called for short SCI), quick paging channel number (NumberofQPCHs), quick paging channel speed (QPCHrate), quick paging channel power level (QPCHpowerlevel), configuration change designator power level (CCIpowerlevel), paging channel number (NumberofPCHchannels), when paging channel speed (RateofPCH) or CDMAchannellist change, need to use configuration change instruction CCI to notify that travelling carriage reads the system parameters changed.
After configuration parameter changes, first quick paging channel will send CCION instruction, and continue 600s; When more than 600s, then send CCIOFF instruction, therefore the change of CCI is equal to the change of system parameters message.
QPCH power is main modulates the relative power level that accords with two relating to parameters: CCI and PI modulates the relative power level accorded with.
The balance between forward link capacity and cell phone standby time will be considered during the relative power level optimum configurations that CCI modulation accords with.The power that this parameter is established is high, then can reduce forward link capacity, but the probability that successfully detects of mobile phone improves, can extending cell phone stand-by time; If the power that this parameter is established is low, then on the contrary.Therefore, if the load of sector carrier frequency is comparatively light, this parameter value can be configured to bigger numerical; If forward direction load is heavier, then need the numerical value reducing this parameter, the suitable parameter value of this parameter is set by balance load and paging success rate.
The relative power level parameter of PI modulation symbol is first set to 2 usually, to ensure paging success rate, then suitably can reduce according to actual conditions.If the load of sector carrier frequency is comparatively light, the numerical value of this parameter is configurable larger; If forward direction load is heavier, then reduce the numerical value of this parameter, the suitable parameter value of this parameter is set by balance load and paging success rate.
The gain span of QPCH is: than the low 5dB of pilot channel to than pilot channel height 2dB, need according to different quick paging channel speed and the gain of concrete network condition amendment quick paging channel.
Experimentally room test result: open QPCH and can promote terminal standby time; When SCI=0, (corresponding paging cycle is 1.28s) opens QPCH, when completely standby without words traffic, can promote the stand-by time of 1 times, terminal; Along with SCI increases (increase of terminal sleep duration), stand-by time promotes ratio and reduces gradually; Along with the increase of terminating traffic amount, the standby time that unlatching QPCH brings promotes and reduces gradually.Traffic model for common: telephone traffic 0.02Erl, BHCA=1/ hour, called, standby time is by lifting more than 50%.
But, by taking substantially suitable with pilot channel forward power resources after the unlatching of QPCH channel, adding forward loading, making system easily there is the risk of forward direction covering or capacity constraint.

The Lower Threshold of the relative pilot of described quick paging channel is set to-∞ dB by step 101, base station controller, and arranges the dynamic range of described quick paging channel transmitting power according to the span of the relative pilot of described quick paging channel;
Step 102, base station controller adjust the transmitting power of described quick paging channel in described dynamic range;
Step 103, base station controller carry out quick paging channel access and load control according to the forward loading thresholding preset to new business.
In the step 101 of the present embodiment, the CCI of QPCH is modulated the actual span of relative power level of symbol and PI modulation symbol from existing-5dB ~+2dB, expand to-∞ ~+2dB, the dynamic range of the transmitting power of QPCH also respective extension thereupon, its minimum value can reach 0W, when QPCH power is 0, terminal cannot read QPCH, therefore must read paging channel, paging channel information can not be lost, and then ensure that the integrality that paging channel information receives.
In a step 102, the transmitting power of QPCH is tentatively adjusted by the new dynamic range of setting, carry out QPCH access and load control by step 103 pair new business again, thus solution QPCH takies the problem that forward emitting power causes forward direction covering, capacity constraint.
In another embodiment, the dynamic range setting operation of the QPCH transmitting power in step 101 is specially: base station controller sets pilot power according to nominal total power, and the dynamic range of QPCH transmitting power is set according to the span of the relative pilot of QPCH, wherein specific formula for calculation is:
The Lower Threshold of quick paging channel transmitting power Lower Threshold=pilot power+relative pilot;
The Upper threshold of quick paging channel transmitting power Upper threshold=pilot power+relative pilot.
Wherein the unit of pilot power is dBm, and the Upper threshold of relative pilot and the unit of Lower Threshold are dB, QPCH power Lower Threshold <=QPCH power Upper threshold.
On the basis of dynamic range determining QPCH transmitting power, the adjustment of QPCH transmitting power is carried out in this dynamic range, concrete adjustment is operating as: base station controller receives the transmitting power of the QPCH that base station reports, and judge whether the transmitting power of QPCH is greater than QPCH transmitting power Upper threshold, in the first adjustment process, reduce the transmitting power of QPCH gradually according to the power drop step-length preset, until the transmitting power meeting QPCH is not more than the condition of QPCH transmitting power Upper threshold, otherwise the transmitting power of QPCH is not adjusted.Namely so-called first adjustment process carries out the adjustment of the transmitting power of QPCH according to the dynamic range of QPCH transmitting power, this adjustment process is the process progressively being reduced the transmitting power of QPCH by default power drop step-length.
