103, carry out discontinuous reception according to the first DRX cycle.

104, when the notice of described first DRX cycle monitors the notice of described base station opportunity, receive the downlink data that described base station sends to described UE.

Such as, downlink data comprises in E-AGCH (absolute grant channel of the dedicated channel that E-DCH Absolute Grant Channel strengthens), E-RGCH (Relative Grant Channels of the dedicated channel that E-DCH Relative Grant Channel strengthens), the upper data sent of HS-SCCH, HS-DSCH or AICH (Acquisition Indicator Channel distributes indicating channel).This definition is equally applicable to other embodiments, and namely downlink data can be that RNC sends to base station, also can be the data that base station self produces.

In embodiments of the present invention, the notice opportunity of the first DRX cycle is obtained according to the DRX parameter of the first DRX cycle and/or the identification code of UE; When carrying out discontinuous reception according to the first DRX cycle, monitor base station opportunity in the notice of the first DRX cycle and whether notify UE, if so, then receive the downlink data that base station sends to UE, due to just receiver downlink data receiving must be opened when only notifying in base station, thus save electric energy.Wherein, due to the power savings identical with CELL_PCH state can be realized, so when realizing saving electric energy, avoid UE frequent migration between CELL_FACH state and CELL_PCH state, and move the transmission of a large amount of signalings brought, thus save Internet resources at every turn.

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, the method that UE can adopt the present embodiment to provide to save electric energy, see Fig. 2.

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

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

Wherein, what DRX parameter can comprise in the Cycle Length factor of the first DRX cycle, the Cycle Length of the first DRX cycle, downlink data time of reception window and the first DRX cycle shot timers is one or more.

Wherein, UE can also arrange downlink data time of reception window and/or the first DRX cycle shot timers in advance with RNC.

202, UE enters when the second DRX cycle carries out discontinuous reception and starts the first DRX cycle shot timers.

Wherein, in the present embodiment, the Cycle Length of the second DRX cycle is less than or equals the Cycle Length of the first DRX cycle.

Wherein, the second DRX cycle comprises down channel time of reception or high-speed Downlink channel time of reception, and down channel non-reception time or high-speed Downlink channel non-reception time, UE monitors down channel continuously at the down channel time of reception of the second DRX cycle or high-speed Downlink channel time of reception, after down channel time of reception or high-speed Downlink channel time of reception terminate, namely UE enters down channel non-reception time or the high-speed Downlink channel non-reception time of the second DRX cycle, UE can open self receiver always, wherein, down channel can comprise HS-SCCH (High Speed Shared Control Channel, High-Speed Shared Control Channel), 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 strengthened), E-RGCH (E-DCH Relative Grant Channel, the Relative Grant Channels of the dedicated channel strengthened), AICH (Acquisition Indicator Channel, distribute indicating channel) in one or more.

203, NB determines the current state of UE, and when UE carries out discontinuous reception according to the second DRX cycle, NB also carries out discontinuous transmission according to the second DRX cycle.

Such as, RNC calculates the Cycle Length of the first DRX cycle according to the Cycle Length factor of the first DRX cycle, the paging occasion in each first DRX cycle is calculated again according to the Cycle Length of calculating and the permanent identification code of UE, RNC, when there being the downlink data needing to send to UE, can send this downlink data and paging occasion to NB.

Such as, NB is when receiving downlink data and the paging occasion of RNC transmission, if NB carries out discontinuous transmission according to the second DRX cycle, then ignore paging occasion and send downlink data to UE by down channel in the down channel time of reception or high-speed Downlink channel time of reception of the second DRX cycle.

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

204, NB, when receiving RNC and sending to downlink data and the paging instruction of UE, sends downlink data to UE, and starts inactive state timer in the down channel time of reception or high-speed Downlink channel time of reception of the second DRX cycle.

Such as, NB is when receiving RNC and sending to downlink data and the paging instruction of UE, judge whether current time is the time of the down channel reception of the second DRX cycle or the time of high-speed Downlink channel reception, if, then directly sending downlink data to UE starts inactive state timer, if not, then to wait for when entering down channel time of reception or the high-speed Downlink channel time of reception of the second DRX cycle, send downlink data to UE and start inactive state timer.

Such as, if NB sent downlink data before inactive state timer expiry, then restart inactive state timer, and continue to send remaining downlink data.If NB did not have downlink data before inactive state timer expiry, then when inactive state timer expiry, carry out discontinuous transmission according to the second DRX cycle.

Such as, when NB sends downlink data in down channel time of reception or high-speed Downlink channel time of reception, inactive state timer can not also be started, and at the end of down channel time of reception or high-speed Downlink channel time of reception, if send downlink data, then continue to carry out discontinuous transmission according to the second DRX cycle, if do not send downlink data, then stop sending downlink data, wait until the down channel time of reception of the second DRX cycle or high-speed Downlink channel time of reception time continue to send remaining downlink data.

Such as, when NB sends downlink data in down channel time of reception or high-speed Downlink channel time of reception, inactive state timer can also be started at the end of down channel time of reception or high-speed Downlink channel time of reception, when not having data to send before this timer expiry, enter the second DRX cycle, if there are data to send before the timeout, restart this timer.

In addition, in another embodiment of the invention, before send the downlink data received from RNC to UE, NB sends control information to UE by down control channels such as E-AGCH, E-RGCH, HS-SCCH or AICH.This action is equally applicable to other embodiments, repeats no more in other embodiments.

205, NB did not have downlink data to send before inactive state timer expiry, then, when inactive state timer expiry, continue to carry out discontinuous transmission according to the second DRX cycle.

Such as, UE, before inactive state timer expiry, as long as receive downlink data, just restarts inactive state timer.If UE, before inactive state timer expiry, does not receive downlink data, then when inactive state timer expiry, carry out discontinuous reception according to the second DRX cycle.

206, UE is before the first DRX cycle shot timers time-out, and as UE receives downlink data, then UE starts inactive state timer, stops the first DRX cycle shot timers, and starts downlink data receiving.

Such as, NB can send downlink data to UE in the down channel time of reception of the second DRX cycle or high-speed Downlink channel time of reception.Such as, before the first DRX cycle shot timers time-out, in the down channel time of reception or high-speed Downlink channel time of reception of the second DRX cycle, UE monitors down channel, if to listen in down channel the downlink data of self, then UE starts inactive state timer, stops the first DRX cycle shot timers, and starts from down channel, receive NB and send to downlink data.

207, if UE does not receive the downlink data that NB sends within inactive state timer expiry, then UE carries out discontinuous reception according to the second DRX cycle, restarts the first DRX cycle shot timers and makes the first DRX cycle shot timers restart timing.

Such as, if be subject to the downlink data of NB transmission before inactive state timer expiry, then UE restarts inactive state timer and restarts timing, then continues the downlink data receiving NB transmission.

208, UE is before the first DRX cycle shot timers time-out, if the downlink data not having NB to send, then UE calculates the Cycle Length of the first DRX cycle according to the first DRX cycle length factor.

209, UE calculates the paging occasion of each first DRX cycle according to the Cycle Length of the permanent identification code of self and the first DRX cycle, then carries out discontinuous reception according to the first DRX cycle.

Wherein, UE calculates the paging occasion of each first DRX cycle, whether paging in monitoring seek channel during paging occasion then in each first DRX cycle.

Wherein, if the DRX parameter of the first DRX cycle comprises the Cycle Length of the first DRX cycle instead of the Cycle Length factor 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, and then carries out the operation calculating paging occasion.

When 210, NB determines that UE carries out discontinuous reception according to the first DRX cycle, carry out discontinuous transmission according to the first DRX cycle.

Wherein, RNC is when there being downlink data to send to UE, and RNC can send paging occasion in downlink data and the first DRX cycle to NB.

211, NB, when receiving paging occasion that RNC sends and sending to the downlink data of UE, sends paging and be indicated to UE, then the downlink data of transmission and reception is to UE when NB is waited for the paging occasion of the first DRX cycle.

Such as, NB receives the paging occasion of the first DRX cycle that RNC sends and sends to the downlink data of UE, NB etc. until the paging occasion of the first DRX cycle time send paging by paging channel and be indicated to UE, and then by the downlink data of down channel transmission and reception to UE.

Wherein, paging channel can be PICH (Paging Indicator Channel Page Indication Channel) channel.In another embodiment of the invention, before send the downlink data received from RNC to UE, NB sends control information to UE by down control channels such as E-AGCH, E-RGCH, HS-SCCH or AICH.This action is equally applicable to other embodiments, repeats no more in other embodiments.

Whether 212, UE monitors NB when the paging occasion of each first DRX cycle have paging, if had, then and downlink data receiving.

Such as, whether UE has paging when the paging occasion of each first DRX cycle in monitoring seek channel, if monitor the paging having self, then in downlink data time of reception window, receives the downlink data that NB sends to self from down channel.Wherein, if UE monitors the paging do not had to self, then continue to carry out discontinuous reception according to the first DRX cycle.

Wherein, when UE receives downlink data in downlink data time of reception window, UE can stop carrying out discontinuous reception according to the first DRX cycle, and start inactive state timer, if receive downlink data at inactive state timer expiry, then restart inactive state timer, if do not receive downlink data before inactive state timer expiry, then when inactive state timer expiry, carry out discontinuous transmission according to the second DRX cycle.

Concrete, step 208 ~ step 212 can use step 213 ~ 217 to replace.

213, UE is before first DRX cycle timer expiry, if NB does not send to the downlink data of this UE, then UE calculates the Cycle Length of the first DRX cycle according to first DRX cycle length factor, or first DRX cycle length is that network side configures to UE; And the length (DRX-on) that first DRX cycle inner receiver is opened is that network side is configurable, or predefined.

214, UE is according to the mutual identifier (H-RNTI of high-speed downstream wireless network, HS-DSCH RadioNetwork Transaction Identifer), calculate paging occasion with first DRX-on length or the first DRX cycle length gauge, then carry out discontinuous reception according to first DRX cycle.

Concrete methods of realizing is: UE calculates out the first DRX mode sequence according to H-RNTI, a DRX-on length and first DRX cycle length gauge; Then using first radio frames of the DRX-on of the first DRX mode sequence or a predefined n radio frames (wherein n is less than or equal to the length of a DRX-on), as paging occasion, wherein n is less than the length of DRX-on; Then discontinuous reception is carried out according to the first DRX mode sequence.Calculate the first DRX mode sequence method to be exemplified below:

(SFN-H-RNTI) mod DRX_cycle < Rx_burst, wherein SFN is System Frame Number, and DRX_cycle is the first DRX cycle length, and RX-burst is a DRX-on length, and mode represents delivery.

For another example, UE according to H_RNTI and the first DRX cycle length computation paging occasion, paging occasion=(H_RNTI) mode DRX_cycle+n*DRX_cycle, wherein n is 1,2 ...., n is less than the maximum of SFN, namely UE the SFN meeting this equation wake up paging receiving instruction.

215, when NB determines that UE carries out discontinuous reception according to first DRX cycle, discontinuous transmission is carried out according to the first DRX cycle.

216, when NB has downlink data to send to UE, NB first in paging occasion at PICH (Page Indication Channel, Paging Indicator Channel) channel sends paging instruction, paging instruction can pass through user ID, calculate as by persistent identifier, computational methods are illustrated: PI (Paging Indicator, paging indicates)=DRX Index mod Np

Where DRX Index=IMSI div 8192, Np is paging instruction number in a frame.

Then send downlink data to UE then.

Wherein paging occasion is predefined between UE and NB, or predefined between RNC and UE, then informs NodeB by RNC; Or RNC configures to UE's and NodeB.PI (paging instruction) informs NodeB after RNC calculates, or RNC is by user ID such as IMSI (IMSI International Mobile Subscriber Identity, International Mobile SubscriberIdentification Number) and Np send to NodeB, by NodeB calculate paging identify PI.

217, UE monitors paging in the paging time of first DRX cycle, if there is the paging of this UE to indicate, then starts wait-receiving mode data.If UE waits for that DRX-on time span does not still receive downlink data, then close receiver until the first DRX cycle terminates, otherwise carry out the continuous of downlink data or discontinuous reception.

If do not listen to the paging instruction of this UE, then close receiver, until just open receiver during the DRX-on of next first DRX mode.

Wherein, when UE receives downlink data in downlink data receive window, UE can continue to carry out discontinuous reception according to the first DRX cycle, and continues to receive down channel in downlink data time of reception window, stops receiving down channel at the non-reception time window of downlink data.

Wherein, when UE receives downlink data in downlink data receive window, UE can continue to carry out discontinuous reception according to the first DRX cycle, when downlink data time of reception window terminates, UE can restart inactive state timer, if also do not receive downlink data before inactive state timer expiry, then restart inactive state timer again, and continue downlink data receiving; If do not receive downlink data before inactive state timer expiry, then return 202; Namely perform from UE carries out disconnected operation according to the second DRX cycle again.

Wherein, in the present embodiment, when NB carries out discontinuous transmission according to the second DRX cycle, NB can notify RNC, makes RNC only send downlink data to NB during NB carries out discontinuous transmission according to the second DRX cycle; When NB carries out discontinuous transmission according to the first DRX cycle, NB can notify RNC, makes RNC send downlink data during NB carries out discontinuous transmission according to the first DRX cycle and paging is indicated to NB.

When the UE that RNC does not receive NB transmission enters the notice of the discontinuous transmission of the first DRX cycle, RNC can carry the relevant parameter of paging in row data frame type 2 at high speeds to NB, by the first DRX cycle discontinuous transmission state of NB according to UE, send paging to UE.RNC also can indicate base station to send paging to UE by sending high-speed down data frame type 3.All applicable in other examples, repeat no more.

In addition, UE and NB first can report and whether support that the ability of the discontinuous transmission of the first DRX cycle carries out the configuration of NB and UE and discontinuous transmit operation determine the ability of UE and NB to RNC, RNC after.RNC notifies that the UE of NB supports that the mode of the first DRX cycle discontinuous reception can by display and implicit expression 2 kinds of modes, the mode wherein shown is the ability that RNC carries a capable field instruction UE in downlink data frame, and wherein the mode of implicit expression supports that the ability characterizing UE is combined in the instruction of general DRX by the parameters such as paging and UE.All applicable in other examples, repeat no more.

In embodiments of the present invention, UE calculates the Cycle Length of the first DRX cycle according to the Cycle Length factor of the first DRX cycle, and the Cycle Length according to the first DRX cycle calculates the paging occasion of UE at each first DRX cycle with the permanent identification code of self; When UE carries out discontinuous reception according to the first DRX cycle, at the paging occasion monitor for pages channel of each first DRX cycle, send to the paging of self to indicate if listen to NB from paging channel, then from down channel, receive the downlink data that NB sends, so save electric energy.Wherein, the efficiency that the method that the present embodiment provides realizes saving electric energy is identical with the efficiency that CELL_PCH state realizes saving electric energy, so the present embodiment is when realizing the object of saving electric energy, avoid UE frequent migration between CELL_FACH state and CELL_PCH state, and move the transmission of a large amount of signalings brought, thus save Internet resources at every turn.

Embodiments provide a kind of power-saving method of CELL_FACH state.In the present embodiment, UE supports to strengthen the UE of up CELL_FACH ability, when UE moves to CELL_FACH state, the method that UE can adopt the present embodiment to provide to save electric energy, see Fig. 3.

301, UE, when moving to CELL_FACH state, receives the DRX cycle parameter that NB sends.

Wherein, the DRX parameter that RNC sends the first DRX cycle receives this DRX parameter to NB, NB and periodically broadcasts this DRX parameter to UE by air interface again, or NB sends specific messages to UE, and this specific messages carries DRX parameter.

Wherein, the DRX parameter of the first DRX cycle can comprise heavy one or more such as the Cycle Length factor of the first DRX cycle, the Cycle Length of the first DRX cycle, down channel time of reception window and inactive state timer.

302, UE judges E-DCH (special uplink channel that the Enhanced uplink DCH strengthens) resource that self whether also there is distribution, if so, then performs 303, if not, then performs 304.

Wherein, when UE needs to send upstream data, first ask network allocation E-DCH resource, and then utilize the E-DCH resource of distributing to send upstream data to network.

303, UE carries out discontinuous reception according to the second DRX cycle, and starts the first DRX cycle shot timers, then perform 305 after waiting for E-DCH resource release.

304, UE enters when the second DRX cycle carries out discontinuous reception and starts the first DRX cycle shot timers.

305-314, identical with the 203-212 of another embodiment or (203-207+213-217) respectively, no longer describe in detail at this.

Wherein, if UE is in the process of carrying out discontinuous reception, when having upstream data to need send and be assigned with the E-DCH resource for sending upstream data, after upstream data sends, UE remains on CELL_FACH state, and then performs from 301.

In embodiments of the present invention, UE calculates the Cycle Length of the first DRX cycle according to the Cycle Length factor of the first DRX cycle, and the Cycle Length according to the first DRX cycle calculates the paging occasion of UE at each first DRX cycle with the permanent identification code of self; When UE carries out discontinuous reception according to the first DRX cycle, at the paging occasion monitor for pages channel of each first DRX cycle, the paging of self is sent to indicate if listen to NB from paging channel, then open receiver and receive from down channel NB send downlink data, so save electric energy.Wherein, the efficiency that the method that the present embodiment provides realizes saving electric energy is identical with the efficiency that CELL_PCH state realizes saving electric energy, so the present embodiment is when realizing the object of saving electric energy, avoid UE frequent migration between CELL_FACH state and CELL_PCH state, and move a large amount of signalings brought, thus save Internet resources at every turn.

Embodiment 9:

901: when UE moves into CELL-FACH state, receive the first DRX cycle length of network side transmission, a DRX-on length (length that the first DRX cycle inner receiver is opened) or a DRX-off length (length that the first DRX cycle inner receiver is closed) and inactive state timer.

Concrete, these parameters are that RNC is by system message or dedicated signaling notice UE; First DRX cycle length equals a DRX-on length and a DRX-off length sum; First DRX cycle length is for determining the Cycle Length of discontinuous reception, one DRX-On is for determining that in discontinuous receiving cycle, the time span of downlink data receiving opened by receiver, and a DRX-off is for determining that in discontinuous receiving cycle, receiver cuts out the time span of not downlink data receiving; Inactive state timer is used for determining to carry out the opportunity of the first DRX mode.

902: concerning the UE supporting common E-DCH (public-to strengthen dedicated channel), after common-E-DCH release, start inactive state timer; Before inactive state timer expires, if receive downlink data, the static timer of rebooting status, if competition is to common E-DCH resource, then stops inactive state timer.

Concerning the UE not supporting common E-DCH, receive downlink data before inactive state timer expires and start (restarting) inactive state timer.After inactive state timer expires, UE enters the first DRX mode state, starts discontinuous reception.

903:UE is according to the mutual identifier (H-RNTI of high-speed downstream wireless network, HS-DSCH RadioNetwork Transaction Identifer), calculate paging occasion with first DRX-on length or the first DRX cycle length gauge, then carry out discontinuous reception according to first DRX cycle.

Concrete methods of realizing is: UE calculates out the first DRX mode sequence according to H-RNTI, a DRX-on length and first DRX cycle length gauge; Then using predefined n the radio frames (wherein n is less than or equal to the length of DRX-on) of first radio frames of the DRX-on of the first DRX mode sequence or the DRX-on of the first DRX mode sequence as paging occasion, wherein n is less than or equal to the length of DRX-on; Then discontinuous reception is carried out according to the first DRX mode sequence.Calculate the first DRX mode sequence method to be exemplified below:

(SFN-H-RNTI) mod DRX_cycle < Rx_burst, wherein SFN is System Frame Number, and DRX_cycle is the first DRX cycle length, and RX-burst is a DRX-on length, and mod represents delivery.For another example, UE according to H_RNTI and the first DRX cycle length computation paging occasion, paging occasion=(H_RNTI) mode DRX_cycle+n*DRX_cycle, wherein n is 1,2 ...., n is less than the maximum of SFN, namely UE the SFN meeting this equation wake up paging receiving instruction.

904:UE monitors PI (PagingIndicator, paging indicates) in above-mentioned paging occasion on PICH (Page Indication Channel), if listen to one's own PI, then whether monitoring has the downlink data of oneself further; If listen to the data of oneself in DRX-on length, then start continuously or discontinuous reception downlink data.

If do not listen to PI in above-mentioned paging occasion, then close receiver, until the first DRX cycle terminates, return step 902.

Such as, first DRX cycle length is 128 radio frames, one DRX-on length is 8 radio frames, paging occasion is first radio frames of DRX-on in the first DRX cycle, then first radio frames of the DRX-On of UE in first DRX cycle monitors PI, do not listen to PI, then close receiver until the first DRX cycle terminates; If listen to PI, then judge further whether monitor one's own H-RNTI on the hs-scch channel in DRX-on, if listened to, then carry out the continuous of downlink data or discontinuous reception, otherwise enter a DRX-off state.

Wherein paging instruction can pass through user ID, calculate as by persistent identifier, computational methods are illustrated: PI=DRX Index (discontinuous reception index) mod Np (in a frame paging instruction number), wherein mod represents the meaning of mould.

Here DRX Index (discontinuous reception index)=IMSI div 8192, Np be in a frame paging instruction number, div represent divided by.
