201, UE when moving to CELL_FACH state, the DRX of the first DRX cycle that network sends Parameter.

Wherein, RNC (Radio Network Controller, radio network controller) is by a DRX week The DRX parameter of phase is sent to NB；NB periodically broadcasts the first DRX cycle by air interface again DRX parameter is to UE, or RNC transmission dedicated signaling is to UE, and this dedicated signaling carries a DRX The DRX parameter in cycle.

Wherein, DRX parameter can comprise the Cycle Length factor of the first DRX cycle, the first DRX cycle It is one or more that Cycle Length, downlink data receive that time window and the first DRX cycle trigger in intervalometer.

Wherein, UE can also arrange downlink data reception time window and/or DRX week in advance with RNC Phase triggers intervalometer.

202, UE enter the second DRX cycle carries out starting the first DRX cycle triggering during discontinuous reception calmly Time device.

Wherein, in the present embodiment, the Cycle Length of the second DRX cycle is less than or equal to a DRX The Cycle Length in cycle.

Wherein, the second DRX cycle includes that down channel receives the time or high-speed Downlink channel receives the time, and Down channel non-reception time or high-speed Downlink channel non-reception time；UE is descending the second DRX cycle Channel receives the time or high-speed Downlink channel receives Time Continuous and monitors down channel, when down channel receives Between or high-speed Downlink channel receive the time terminate after i.e. UE to enter the down channel of the second DRX cycle non-reception Time or high-speed Downlink channel non-reception time, UE can self receiver always on, wherein, Down channel can include that (High Speed Shared Control Channel shares at a high speed control to HS-SCCH Channel processed), HS-DSCH (High Speed Down Shared Channel, high speed descending sharing channel), E-AGCH (E-DCH Absolute Grant Channel, the absolute grant channel of the dedicated channel of enhancing), E-RGCH (E-DCH Relative Grant Channel, the Relative Grant Channels of the dedicated channel of enhancing), One or more in AICH (Acquisition Indicator Channel, distribution instruction channel).

203, the NB current states determining UE, when UE carries out discontinuous reception according to the second DRX cycle Time, NB carries out discontinuous transmission also according to the second DRX cycle.

Such as, RNC calculates the week of the first DRX cycle according to the Cycle Length factor of the first DRX cycle Phase length, the permanent identification code further according to the Cycle Length calculated and UE calculates each first DRX cycle In paging occasion, RNC when there is a need to the downlink data being sent to UE, can send this downlink data and Paging occasion is to NB.

Such as, NB is when receiving downlink data that RNC sends and during paging occasion, if NB is according to the Two DRX cycles carry out discontinuous transmission, then ignore paging occasion the down channel at the second DRX cycle Reception time or high-speed Downlink channel send downlink data to UE by down channel in receiving the time.

Such as, the permanent identification code of UE can be IMSI, or other are for identifying the mark of UE.

204, NB when receiving downlink data and the paging instruction that RNC is sent to UE, at the 2nd DRX In the down channel reception time in cycle or high-speed Downlink channel reception time, transmission downlink data is to UE, and opens Sound stops condition timer.

Such as, NB is when receiving downlink data and the paging instruction that RNC is sent to UE, it is judged that current The time that whether time be time of receiving of the down channel of the second DRX cycle or high-speed Downlink channel receives, If it is, directly transmit downlink data to UE and start resting state intervalometer, if it is not, then wait into When entering down channel reception time or the high-speed Downlink channel reception time of the second DRX cycle, send lower line number According to UE and startup resting state intervalometer.

Such as, if NB sent downlink data before resting state timer expiry, then resting state is restarted Intervalometer, and continue to send remaining downlink data.If NB did not had before resting state timer expiry Downlink data, then carry out discontinuous transmission according to the second DRX cycle when resting state timer expiry.

Such as, NB sends downlink data in down channel receives time or high-speed Downlink channel reception time Time, it is also possible to do not start resting state intervalometer, and connect in down channel reception time or high-speed Downlink channel At the end of between the time receiving, if having sent downlink data, then continue to carry out discontinuous according to the second DRX cycle Send, without having sent downlink data, then stop sending downlink data, wait until second DRX cycle Down channel receives the time or high-speed Downlink channel continues to send remaining downlink data when receiving the time.

Such as, NB sends downlink data in down channel receives time or high-speed Downlink channel reception time Time, it is also possible at the end of down channel receives time or high-speed Downlink channel reception time, start resting state Intervalometer, when not having data to send before this timer expiry, enters the second DRX cycle, if before the timeout There are data to send and then restart this intervalometer.

It addition, in another embodiment of the invention, sending before the downlink data that RNC receives to UE, NB can be sent by down control channels such as E-AGCH, E-RGCH, HS-SCCH or AICH and control letter Breath is to UE.This action is equally applicable to other embodiments, repeats no more in other embodiments.

205, NB did not had downlink data to send before resting state timer expiry, then fixed in resting state Time device time-out when, continue carry out discontinuous transmission according to the second DRX cycle.

Such as, UE is before resting state timer expiry, as long as receiving downlink data, just restarts static Condition timer.If UE is before resting state timer expiry, it is not received by downlink data, then exists When resting state timer expiry, carry out discontinuous reception according to the second DRX cycle.

206, UE before the first DRX cycle triggers timer expiry, as UE receives downlink data, then UE starts resting state intervalometer, stops the first DRX cycle and triggers intervalometer, and starts to receive lower line number According to.

Such as, NB can be when the down channel of the second DRX cycle receives the time or high-speed Downlink channel receives The interior downlink data that sends is to UE.Such as, trigger before timer expiry at the first DRX cycle, the The down channel of two DRX cycles received in time or high-speed Downlink channel reception time, and UE monitors descending letter Road, if listening to the downlink data of self in down channel, then UE starts resting state intervalometer, stops First DRX cycle trigger intervalometer, and start from down channel receive NB be sent to downlink data.

207, if UE is not received by the downlink data that NB sends within resting state timer expiry, Then UE carries out discontinuous reception according to the second DRX cycle, restarts the first DRX cycle and triggers timing Device also makes the first DRX cycle triggering intervalometer restart timing.

Such as, if the downlink data sent by NB before resting state timer expiry, then UE is again Start resting state intervalometer and restart timing, then proceeding to receive the downlink data that NB sends.

208, UE trigger before timer expiry at the first DRX cycle, without NB send descending Data, then UE calculates the Cycle Length of the first DRX cycle according to the first DRX cycle length factor.

410, if UE did not receive NB before resting state timer expiry and is sent to the lower line number of UE According to, then UE carries out discontinuous reception according to the first DRX cycle when resting state timer expiry again.

Wherein, after UE carries out discontinuous reception according to the first DRX cycle again, return 405 and start to hold OK.

Wherein, if UE is the UE supporting E-DCH resource, then when UE is in the mistake carrying out discontinuous reception Cheng Zhong, when having upstream data to need send and be assigned with the E-DCH resource for sending upstream data, when upper After row data have sent, UE is maintained at CELL_FACH state, starts to perform from 401 the most again.

Optionally, UE can start resting state intervalometer, when static when entering CELL_FACH state Do not receive downlink data before condition timer time-out and then enter the first DRX cycle discontinuous reception.This point is same Sample is applicable to other embodiment.

Embodiments provide a kind of power-saving method in CELL_FACH state.In the present embodiment, UE is the UE not supporting to strengthen up CELL_FACH ability, when UE moves to CELL_FACH state Time, UE can use method that the present embodiment provides to save electric energy, see Fig. 5.

501, UE when moving to CELL_FACH state, receives the first DRX cycle of NB transmission DRX parameter, and this DRX parameter at least includes the Cycle Length factor of the first DRX cycle.

Wherein, the DRX parameter of the first DRX cycle is sent to NB by RNC；NB passes through air interface again Periodically broadcast the DRX parameter of the first DRX cycle to UE, or NB send dedicated signaling to UE, And this dedicated signaling carries the DRX parameter of the first DRX cycle.

Wherein, DRX parameter can also include that downlink data receives time window.It addition, RNC can pass through DRX parameter directly transmits the Cycle Length of the first DRX cycle, and does not send the cycle of the first DRX cycle Length factor.

Wherein, for support strengthen up CELL_FACH UE, UE after receiving DRX parameter, Further determine whether the E-DCH resource of distribution, if it is not, directly perform 502, if it has, then etc. After E-DCH resource discharges, then perform 502.

502, UE carry out discontinuous reception according to the second DRX cycle, and start the first DRX cycle triggering Intervalometer.

Wherein, the second DRX cycle includes that down channel receives the time or high-speed Downlink channel receives the time, and Down channel non-reception time or high-speed Downlink channel non-reception time；UE is descending the second DRX cycle Channel receives the time or high-speed Downlink channel receives Time Continuous and monitors down channel, when down channel receives Between or high-speed Downlink channel receive the time terminate after i.e. UE to enter the down channel of the second DRX cycle non-reception Time or high-speed Downlink channel non-reception time, UE can cease listening for down channel, and wherein, down channel can To include one or more of HS-SCCH and/or HS-DSCH, E-AGCH, E-RGCH, AICH etc..

503, the NB current states determining UE, when UE carries out discontinuous reception according to the second DRX cycle Time, NB carries out discontinuous transmission also according to the second DRX cycle.

504, NB when receiving the downlink data that RNC is sent to UE, under the second DRX cycle In row channel reception time or high-speed Downlink channel reception time, transmission downlink data is to UE, and starts static shape State intervalometer.

Such as, NB is when receiving the downlink data that RNC is sent to UE, it is judged that the most whether UE is The down channel of two DRX cycles receives the time or high-speed Downlink channel receives the time, if it is, directly send out Downlink data is sent to UE and to start resting state intervalometer, if it is not, then wait and enter the second DRX cycle Down channel receive time or high-speed Downlink channel when receiving the time, send downlink data and to UE and start quiet Only condition timer.

505, NB did not had downlink data to send before resting state timer expiry, then fixed in resting state Time device time-out when, continue carry out discontinuous transmission according to the second DRX cycle.

506, UE before the first DRX cycle triggers timer expiry, if NB has is sent to UE's Downlink data, then UE starts resting state intervalometer, stops the first DRX cycle and triggers intervalometer, and opens Begin to receive downlink data.

Wherein, NB can be when the down channel of the second DRX cycle receives the time or high-speed Downlink channel receives The interior downlink data that sends is to UE.Such as, trigger before timer expiry at the first DRX cycle, the The down channel of two DRX cycles received in time or high-speed Downlink channel reception time, and UE monitors descending letter Road, if listening to the downlink data having NB to be sent to self in down channel, then UE starts resting state Intervalometer, stop first DRX cycle trigger intervalometer, and start from down channel receive NB be sent to The downlink data of self.

507, if UE does not receive downlink data at resting state timer expiry, then UE is according to second DRX cycle carries out discontinuous reception, restarts the first DRX cycle and triggers intervalometer and make a DRX Cycle triggers intervalometer and restarts timing.

Wherein, if receiving downlink data before resting state timer expiry, then UE restarts static shape State intervalometer also restarts timing, then proceedes to receive the downlink data that NB sends.

508, UE before the first DRX cycle triggers timer expiry, without receiving what NB sent Downlink data, then UE enters the first DRX cycle discontinuous reception.

509, UE identify according to self private wireless network, the Cycle Length of the first DRX cycle and/or company Continued access is received the one or more parameters in window and is calculated the group mark reception opportunity of the first DRX cycle, then root Discontinuous reception is carried out according to the first DRX cycle.

Wherein, in the present embodiment, in advance the UE in network is divided into different groups, and each group includes UE have identical group to identify.

Wherein, if the DRX parameter of the first DRX cycle includes the Cycle Length of the first DRX cycle, Then UE directly reads the Cycle Length of the first DRX cycle from the DRX parameter of the first DRX cycle, so After carry out calculating the operation on reception group mark reception opportunity again.

Wherein, receive continuously window and can receive window with downlink data, or the connecing of special reception group mark Receive window.This window can also use the mode of agreement.

510, NB determine when UE carries out discontinuous reception according to the first DRX cycle, according to a DRX Cycle carries out discontinuous transmission.

Wherein, RNC is when there being downlink data to be sent to UE, and RNC can send the nothing of downlink data and UE Gauze identifies to NB.

511, NB when receiving RNC and sending downlink data, then wait until the group mark of the first DRX cycle When knowing reception opportunity, the group sending UE identifies to UE, retransmits the downlink data of reception to UE.

Such as, NB, when receiving the downlink data that RNC is sent to UE, waits until the first DRX cycle Group mark reception opportunity time, obtain the group mark of UE according to special wireless network identification, by public control Channel processed sends the group of UE and identifies to UE, sends downlink data to UE by down channel the most again.

Wherein, RNC is when sending downlink data, and the optional group mark simultaneously sending UE, so NB can To directly receive the group mark of UE；Or RNC configuration group identification list on NB in advance, NB is when receiving To RNC send downlink data time, according to downlink data include UE wireless network mark, according to UE Wireless network mark select UE group mark.

512, UE etc. until monitoring whether NB is sent to during group mark reception opportunity of the first DRX cycle The group mark of self, if it has, then receive NB to be sent to the downlink data of self.

Such as, if UE listens to NB and sends the group mark of self, then prison is identified according to the wireless network of self Listen and whether down channel has NB be sent to the downlink data of self, if it has, then when downlink data receives Between receive NB from down channel in window and be sent to the downlink data of self.

Wherein, if UE does not listen to the group mark of self opportunity in the mark reception of organizing of the first DRX cycle Know, then UE continues to carry out discontinuous reception according to the first DRX cycle.

Wherein, if UE is after the group mark reception of the first DRX cycle listens to the group mark of self opportunity, But do not listen to NB in down channel and be sent to the downlink data of self, then UE continues according to first DRX cycle carries out discontinuous reception.

Wherein, when UE receives downlink data in downlink data receives window, start resting state intervalometer, If receiving again downlink data in resting state timer expiry, restart resting state intervalometer, if static The most do not receive downlink data in condition timer time-out and then enter the second DRX cycle discontinuous reception.

Wherein, when UE keeps receiving down channel in downlink data receives window, resting state can not be started Intervalometer, stops receiving down channel at the end of downlink data receives window, keeps the first DRX cycle non- Receive continuously.

Wherein, at the end of downlink data receives time window, resting state intervalometer is started, if at static shape Receive downlink data before state timer expiry, restart resting state intervalometer, if in resting state timing The most do not receive downlink data before device time-out and enter the second DRX cycle discontinuous reception.

In embodiments of the present invention, UE calculates first according to the Cycle Length factor of the first DRX cycle The Cycle Length of DRX cycle, according to private wireless network mark, the Cycle Length of the first DRX cycle and/or The continuous one or more parameters received in window calculate UE and connect in the group mark of each first DRX cycle Time receiving machine；When UE carries out discontinuous reception according to the first DRX cycle, at each first DRX cycle Group mark receive opportunity monitor CCCH, if listen to NB sends self group identify, then from Down channel receives the downlink data that NB sends, so saves electric energy.Wherein, the side that the present embodiment provides It is identical with the efficiency that electric energy is saved in the realization of CELL_PCH state that method realizes the efficiency saving electric energy, so this enforcement Example is when realizing the purpose saving electric energy, it is to avoid UE is between CELL_FACH state and the CELL_PCH state Frequent migration, and migrate the transmission of a large amount of signalings brought every time, thus save Internet resources.
