Embodiment 2

Referring to Fig. 2, the embodiment of the present invention provides a kind of method that realizes discontinuous reception, comprising:

201:RN completes start-up course, connects with DeNB (Donor E-UTRAN Node B, donor base station) and core net.

Wherein, RN has little base station functions, and RN can manage a plurality of UE that reside in RN community.After RN and DeNB and core net connect, some UE in RN community will carry out the process that RRC (Radio Resource Control, Radio Resource is controlled) connects or discharges with RN.

The context of the Radio Resource control connection of the UE in 202:RN monitoring RN community, after RN monitors the context that there is no the Radio Resource of UE control connection in RN, RN determines that RN can enter RN-cell-DRX pattern (via node community DRX pattern).

Wherein, RN-cell-DRX pattern refers to that the interface between RN and DeNB enters DRX pattern, is DRX state, and RN keeps being normally connected with the Radio Resource control connection between DeNB, and the interface between RN and UE keeps normal pattern, is non-DRX state.

Wherein, when RN monitors the context that there is no the Radio Resource of UE control connection in RN, prove that the context of all connected state UE in RN community has all discharged, thereby proof there is no UE to have and be connected with its foundation.When having UE to set up to have with RN, be not connected, illustrate that the UE used in RN community has entered Idle state, in HuoRN community, do not have UE resident, now RN can enter RN-cell-DRX pattern.

It should be noted that, accuracy when guaranteeing that further RN enters RN-cell-DRX pattern, RN is when determining that it can enter the DRX pattern of connected state, except according to not having in RN the context of Radio Resource control connection of UE, can also be simultaneously according to the dump energy of RN self, current situation in daytime, sunlight strength, historical business frequent degree and/or the factors such as load of RN, decide RN whether can enter the DRX pattern of connected state.For example: when RN monitors the context that there is no the Radio Resource of UE control connection in RN, and the dump energy of RN self is during lower than default power threshold, and RN determines that RN can enter RN-cell-DRX pattern.Again for example: when RN monitors the context that there is no the Radio Resource of UE control connection in RN, the dump energy of RN self is lower than default power threshold, and current time while being night, RN determines that RN can enter RN-cell-DRX pattern.In practical application, RN, when determining whether it can enter RN-cell-DRX pattern, can carry out flexible combination by above-mentioned various conditions according to practical application situation.

203a:RN is that RN configuration RN-DRX cycle and RN-DRX control parameter, in configuration RN-DRX cycle and RN-DRX, controls after parameter, makes the interface between RN and DeNB enter DRX pattern; 203b: and RN controls parameter by himself current DRX mode state, RN-DRX cycle and RN-DRX and informs DeNB.

Wherein, DRX mode state comprises: DRX state and non-DRX state.RN-DRX controls parameter and comprises: the length of window of RN-DRX cycle original position, the number of sub frames at RN-DRX original position continuous monitoring downlink physical control channel, the sluggish duration that enters DRX deactivation status and wait data re-transmission etc.Can adopt the method for prior art, the value of DRX being controlled to the parameters comprising in parameter according to concrete application scenarios is configured, and this is not specifically limited.And, the parameters such as length of window in the number of sub frames of DRX original position continuous monitoring downlink physical control channel, the sluggish duration that enters DRX deactivation status and wait data re-transmission can realize by the mode of timer, as: timer (onDurationTimer), DRX deexcitation timer (drx-InactivityTimer), DRX retransmission timer (drx-RetransmissionTimer) of connection monitoring PDCCH (Physical Downlinkcontronl Channel, physical downlink control channel) channel etc. can be set.

Wherein, at configuration RN-DRX, during the cycle, at least can realize in the following way:

1) be configured to any one value in the paging cycle of UE the RN-DRX cycle.

Particularly, the value of the paging cycle of UE is any one in (320ms, 640ms, 1280ms and 2560ms) at present, can be according to RN to the demand of paging time delay and power saving in various degree, be configured to any one value in the paging cycle of UE the RN-DRX cycle, as the RN-DRX cycle of RN being configured to 320ms or 2560ms etc.

2) the RN-DRX cycle is configured to 320*k millisecond, wherein k is positive integer;

From 1) different be during the cycle, not only the RN-DRX cycle can be configured to current paging cycle at configuration RN-DRX, the RN-DRX cycle can also be configured to current paging cycle to do the value after expanding.

3) according to MME (Mobile Management Entity, Mobility Management Entity) page response time Ms, default paging frequency n, from idle (idle) state of UE, to MME, receive the time Ws of page response and the paging cycle T of UE, the RN-DRX cycle y that configures RN is:

y＝[(Ms*n-T-Ws)div320]*320ms

Wherein, y=[x] be called bracket function, be also Gaussian function.Can choose according to practical application situation the concrete value of n, Ms, T and Ws.Wherein, the general value of T is the maximum in the paging cycle of all UE of corresponding system standard regulation, as: in LTE-A system, the value of the paging cycle of standard regulation UE is any one value in (320ms, 640ms, 1280ms and 2560ms) at present, and therefore choosing T is 2560ms.

Particularly, for example, in the open stage that powers on (start up) of RN, the page response time Ms of RN acquisition MME (as, at present the page response time of MME is 6s, and the page response time Ms of the MME therefore obtaining is 6s, and paging frequency n is set is 2).Simultaneously, according to the requirement definition of 3GPP, determine from UE Idle state to MME, receive page response time Ws (for example: at present, the mean value of receiving the time of page response for LTE from UE Idle state to MME is 35.5ms, the mean value of receiving the time of page response for LTE-A from UE Idle state to MME is 18.5 milliseconds, from the angle of backward compatibility, selection Ws is 35.5ms, is about 40ms).From UE Idle state, to MME, receive page response, should under the prerequisite of beep-page message of not losing UE, make the RN power saving of can trying one's best, therefore the RN-DRX that configures RN at the paging cycle that utilizes UE is during the cycle, the paging cycle that should choose UE is as far as possible longer, maximum in all paging cycle that the paging cycle T that for this reason chooses UE is UE (for example: the value of the paging cycle of UE is any one in (320ms, 640ms, 1280ms and 2560ms) at present, the RN-DRX that configures RN at the paging cycle that utilizes UE is during the cycle, and the paging cycle of choosing UE is 2560ms).Thereby the RN-DRX cycle y that obtains RN is: y=[(6000*2-2560-40ms) div320] * 320ms=9280ms.

It should be noted that, at actual disposition RN-DRX during the cycle, can dynamically change according to practical application situation the value of Ms, n, T and Ws in [(Ms*n-T-Ws) div320] * 320 milliseconds, also can Ms, n, the value of T and Ws is set to fixing value, as Ms being fixedly installed into 6s, it is 2 that paging frequency n is fixedly installed, and T is fixedly installed as 2560ms, and Ws is fixedly installed as 40ms.

And, RN can according to current to the demand of paging time delay and power saving in various degree from (320ms, 640ms, 1280ms, 2560ms and [(Ms*n-T-Ws) div32] ms), select a value as the RN-DRX cycle.For example: if by day, because there is sunlight, the demand of power saving does not get the upper hand, and considers paging time delay, can select the less values such as 320ms, 640ms; If at night, business is not too frequent, and the demand of power saving gets the upper hand, and can select value that [(Ms*n-T-Ws) div320] * 320ms etc. is larger.

It should be noted that, the interface between RN and DeNB enters DRX pattern, according to RN-DRX cycle and RN-DRX, controls the information between parameter transmission RN and DeNB.It should be noted that, in order can normally to work ShiRN community, now the interface between RN and UE is still non-DRX state, i.e. normal state.

It should be noted that in addition, this step RN just enters RN-cell-DRX pattern after configuration RN-DRX cycle and RN-DRX control parameter, in practical application, can also be, referring to Fig. 2 a, RN controlled after parameter (step 203c) in configuration RN-DRX cycle and RN-DRX, and RN sends an information current DRX mode state, RN-DRX cycle and the RN-DRX control parameter of RN informed to DeNB (step 203d).When DeNB agrees to the interface between RN and DeNB, enter RN-cell-DRX pattern, after returning and determining that response message is to RN, after RN receives, enter again RN-cell-DRX pattern (step 203e); When DeNB disagrees with the interface between RN and DeNB, enter RN-cell-DRX pattern, return negative response message to RN after, RN cannot enter RN-cell-DRX pattern.And, particularly, RN controls parameter by the state of the DRX pattern of RN, RN-DRX cycle and RN-DRX and informs DeNB, can realize by the direct mode to DeNB transmission information, also can realize by the mode of updating message (is non-DRX states as the default conditions of RN are set, when RN enters DRX pattern, then be updated to DRX state).

Or can also be when definite RN can enter RN-cell-DRX pattern, RN configuration DRX cycle and DRX control parameter, RN controls parameter by himself current DRX mode state, DRX cycle and DRX and informs base station, and enters RN-cell-DRX pattern.

Or can also be when definite RN can enter RN-cell-DRX pattern, RN sends the request command that enters DRX pattern to DeNB, after DeNB agrees to, for RN configuration DRX cycle and DRX control parameter, and send and determine response message to RN, receiving agreement that DeNB sends, it enters DRX pattern really after provisioning response message to RN, enters RN-cell-DRX pattern.

204:MME sends beep-page message to DeNb, and the UE in notice RN community receives incoming call.

205: when DeNB receives the beep-page message that MME sends, DeNB controls parameter according to RN-DRX cycle and RN-DRX, the arbitrary moment being chosen between the active period of RN sends this beep-page message to RN.

Wherein this beep-page message comprises the paging sign of UE and the paging DRX cycle of UE.

206: when RN receives the beep-page message of DeNB transmission, RN calculates paging frame and the paging time-slot of paging UE according to the paging DRX cycle of UE.

Specifically similarly to the prior art, repeat no more herein.

207:RN is according to the paging frame of UE and paging time-slot, and RN sends beep-page message in community, and the paging sign of UE is filled out in paging acknowledgment IE.

Wherein, the beep-page message that RN sends is to use P-RNTI (PAIGN-Radio Network TemporaryIdentifier, pager wireless net network temporary mark) scrambling.

208a: after paged the arriving of UE in DangRN community, UE initiates Radio Resource control connection to RN and sets up request; 208b:RN makes the interface between RN and DeNB exit DRX pattern.

It should be noted that, can also be specifically that UE initiates after Radio Resource control connection foundation request to RN, and DeNB makes the interface between RN and DeNB exit DRX pattern.

The method that realizes discontinuous reception described in the embodiment of the present invention, according to the discontinuous reception DRX pattern of connected state terminal or the traffic load of base station in the Radio Resource control connection of the terminal in via node and this via node community, via node community, control via node and enter DRX pattern, make the RN can power and energy saving.And RN can be according to the page response time of the paging cycle of UE, MME and the configuration RN-DRX cycles such as time of receiving page response from UE Idle state to MME, configuration RN-DRX periodic mode is flexible.
