Description
Technical field
The embodiment of the invention relates to the communications field, and more specifically, relates to method and the device of discontinuous reception (DRX, Discontinuous Reception).
Background technology
The service environment of mobile Internet has been overturned the traffic model of traditional circuit domain business, business model such as the QQ under the intelligent machine (Smartphone), application memory (AppStore), the blackberry, blueberry (BlackBerry) of typical mobile Internet, pushes away spy's application such as (Twitter).For synchronous service and keep heartbeat, will transmit data in order to correspondingly trigger paging and be connected flow process such as foundation every very short time (tens seconds, a few minutes) in the network, thereby cause the load of network sharply to raise.
In order to reduce the expense of state conversion in the business model variation, introduced an intermediateness in the Long Term Evolution (LTE, Long TermEvolution), i.e. the discontinuous reception of connected state (Active DiscontinuousReception, Active DRX) mechanism.Connected state DRX mechanism allows subscriber equipment, and (UE, UserEquipment) (Radio Resource Control RRC) periodically changes between sleep state and state of activation under the state of Lian Jieing keeping Radio Resource control.
Connected state DRX mechanism is divided into state of activation stage and sleep state stage with the connected state of UE.When UE is in state of activation during the stage, the reception antenna of UE is opened, so that UE downlink data receiving bag, this moment, the power consumption of UE was higher; When UE is in the sleep state stage, the reception antenna of UE is closed, and UE can not the downlink data receiving bag, and this moment, UE was in battery saving mode, but the context that RRC connects still keeps.
Existing connected state DRX mechanism enters sleep state some little free times before the stage to UE, for example UE sends dispatch request (schedule request, SR) wait for evolved base station (eNB or e-NodeB after the message, evolutional Node B) in Tiao Du the process and at the automatic repeat requests of mixing (Hybrid Automatic Repeat Request, HARQ) do not have in the stand-by period that message retransmits under the situation that other packet sends, UE still needs to remain on the state of activation stage, thereby need constantly detect Physical Downlink Control Channel (physical downlink control channel, PDCCH), cause UE power consumption more.In addition, the variation of connected state DRX cycle is to realize by changing the RRC signaling configuration, therefore adjust connected state DRX mechanism length consuming time by changing the connected state DRX cycle, postpone big and dumb.And, needing temporary changes DRX parameter or do not disposing at UE under the situation of DRX parameter, eNB can't indicate UE to enter sleep state fast.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The technical scheme of the embodiment of the invention, UE also can be referred to as portable terminal (Mobile Terminal), mobile subscriber equipment etc., can be through wireless access network (for example, RAN, Radio Access Network) communicates with one or more core net, subscriber equipment can be portable terminal, as mobile phone (or being called " honeycomb " phone) with have the computer of portable terminal, for example, can be portable, pocket, hand-hold type, mobile device built-in computer or vehicle-mounted, they and wireless access network exchange language and/or data.
From the UE aspect, power saving is endless, and especially along with the popularizing of instant messaging service, the power saving of UE becomes more important.Even if in existing connected state DRX mechanism, still there is the possibility of further optimizing, for example UE is after sending SR message, need to wait for the schedule information of eNB, in this process, still might there be free time, but should free time carries out once original connected state DRX mechanism again inadequately.In this case, can introduce new method, allow UE economize on electricity more.
Base station side is described according to the method for the DRX of the embodiment of the invention referring to Fig. 1.As shown in Figure 1.
11, eNB determines whether to dispatch in a period of time UE.
12, if determine not dispatch UE in this time period, eNB sends additional DRX order to this UE, and this additional DRX order was used to indicate this UE and carries out DRX to be in sleep state in this time period.
ENB sent additional DRX order to UE after, with reference to shown in Figure 2, the UE lateral root may further comprise the steps according to the method for the DRX of the embodiment of the invention:
21, UE receives the additional DRX order that the base station sends;
22, UE carries out DRX to be in sleep state in a period of time according to the indication of additional DRX order.
The method of the DRX of the embodiment of the invention can make that UE is quicker in not by the free time of base station scheduling and enter dormant problem, make under the prerequisite of the existing DRX configuration that does not change UE, do not have the segment of packet transmission or reception to pass through the new sleep pattern of triggering execution that additional DRX orders in free time at UE, thereby UE economize on electricity more.
From the above, the connected state DRX cycle comprises state of activation stage and sleep state stage, and wherein in the state of activation stage, UE monitors Physical Downlink Control Channel, in order to obtain the schedule information that eNB sends; And in the sleep state stage, UE does not monitor Physical Downlink Control Channel, and is in the sleep pattern.Therefore, time period is shorter than the state of activation stage of connected state DRX cycle.
Particularly, additional DRX order comprises the information of the execution duration that is used to indicate DRX.Therefore, no matter whether dispose the DRX parameter of connected state DRX mechanism in the network, sent above-mentioned additional DRX order as long as UE receives eNB, will in the indicated time period, carry out sleep pattern according to the information of the execution duration of the above-mentioned DRX of being used to indicate.
Further, for the situation of the DRX parameter that has disposed connected state DRX mechanism, except the DRX that starts single optimization, can also start the DRX that repeatedly optimizes.Like this, additional DRX order can comprise that being used to indicate UE carries out the information of number of times of DRX and the information that is used to indicate the execution duration of each DRX in a period of time.The execution duration of DRX is not more than this time period, and namely UE carries out the short DRX sleep of one or many in this time period.Whenever carrying out once short DRX, UE enters sleep state one time, thereby saves power consumption.
In addition, the information that is used to indicate the duration of each DRX can comprise the information of duration that UE adopts the DRX cycle of the information of DRX cycle of long or short optimization and optimization this length or weak point that is used to indicate, wherein, the DRX cycle of optimization this length or short is shorter than the state of activation stage of connected state DRX cycle.The duration of each DRX is optional, and present embodiment provides the DRX cycle of long optimization and two kinds of selections of DRX cycle of the optimization of weak point, and every kind of selection all is to having a kind of optimization of DRX sleep mechanism now.The base station can be the DRX cycle that UE selects proper optimization based on the practical application scene, makes UE not enter sleep in the time period of UE data dispatching in the base station.
Like this, UE can be according to the DRX of additional DRX command execution single or multiple optimization.
Describe the detailed process of the DRX that UE and eNB be optimized in detail below in conjunction with Fig. 3.
As shown in Figure 3, when UE has entered connection mode, and carry out in the process of proper communication with eNB, if eNB determines can not dispatch this UE in a bit of time, then trigger UE and start DRX.At this moment, eNB sends additional DRX order to UE, and indication UE carries out DRX.The DRX order can (Media Access Control, MAC) the additional DRX of layer orders and obtained, and need not to revise the DRX parameter by the RRC transmitting signaling downwards by revising the medium access control owing to should add.Generally speaking, the DRX parameter comprises: duration timer (onDurationTimer), the non-Active Timer of DRX (drx-InactivityTimer), DRX retransmission timer (drx-RetransmissionTimer), long DRX cycle skew (longDRX-CycleStartOffset), short DRX cycle (shortDRX-Cycle) and DRX short cycle timer (drxShortCycleTimer) etc.
Particularly, if UE has disposed the DRX parameter or has started connected state DRX mechanism this moment, but eNB determines this a bit of free time and the DRX parameter that has been configured or the connected state DRX mechanism of startup and does not match, for example the connected state DRX cycle is configured to 20 subframes, but eNB determines this a bit of free time and has only 2 subframes, carry out once complete connected state DRX cycle inadequately, eNB just allows UE sleep according to additional DRX order by triggering single or multiple DRX, namely allow UE 2 subframes of only sleeping, make that like this UE fully economizes on electricity.After the DRX that single or multiple is optimized finished, UE and eNB needed to recover original connected state DRX mechanism.For example, originally but the UE that had disposed the DRX parameter be not activated connected state DRX mechanism will still not start connected state DRX mechanism, the UE that had perhaps disposed the DRX parameter originally and started connected state DRX mechanism still continues original connected state DRX mechanism, namely carries out connected state DRX mechanism according to original DRX parameter.
Be appreciated that if UE does not dispose the DRX parameter, also be not activated connected state DRX mechanism, then eNB is just easier makes UE carry out the length of one's sleep of appointment by triggering single DRX.But, if UE has disposed the DRX parameter, then can carry out repeatedly DRX, can utilize timers such as duration timer, begin to enter sleep in the suitable moment.
How to dispose additional DRX below in conjunction with the specific embodiment description of Fig. 4 and Fig. 5 and order to start single or multiple DRX.Additional DRX order is different from connected state DRX order.
For example, eNB has 2 bytes (Byte) to the additional DRX order that UE sends, wherein the 1st byte used 1 bit (bit) in the obligate information position of connected state DRX order, for example utilize Fig. 4 to the 2nd bit shown in Figure 7, the DRX order of indicating eNB to send to UE is additional DRX order or connected state DRX order.Generally speaking, connected state DRX order has only 1 byte, and wherein preceding 2 bits are as the obligate information position, and the 3rd bit be as the extend information position, back 5 bits as locale identifier (Localization Identity, LCID).
In addition, the information of the execution number of times that comprises the execution duration of DRX or DRX in the 2nd byte of additional DRX order and the DRX cycle of the execution duration of each DRX or long or short optimization and with the information such as duration of the corresponding DRX additional cycle of the DRX cycle of optimization long or weak point, following several mode specifically can be arranged.Need to prove that in the described mode, the positional alignment of bit can change below, and all at the protection range of the embodiment of the invention:
First kind of mode, all 8 bits are used to indicate the execution duration of DRX, are unit with the subframe, for example 00000001 indicate sleep 1 subframe, 00000011 indication sleep, 3 subframes, etc.As shown in Figure 4.
The second way, preceding 3 bits are used to indicate the number of times that DRX carries out, and for example 000 is used for expression single DRX, and 001 is used for 2 DRX of expression .... and the like, be used for 8 DRX of expression up to 111.4-8 bit is used to indicate the execution duration of concrete DRX, is unit with the subframe.As shown in Figure 5.
The third mode, preceding 3 bits are used to indicate the number of times that DRX carries out, and for example 000 is used for expression single DRX, and 001 is used for 2 DRX of expression .... and the like, be used for 8 DRX of expression up to 111.The 4th bit is used to indicate long or short DRX cycle.4 last bits are used to indicate the length of concrete DRX additional cycle.As shown in Figure 6.
The 4th kind of mode, preceding 2 bits are used to indicate the number of times that DRX carries out, and for example 00 to 11 expression repeatedly adopts the 3rd bit to indicate single DRX, as shown in Figure 7 again.In remaining 5 bits, can adopt 1 bit to indicate long or short DRX cycle, other 4 bits are indicated the length of concrete DRX additional cycle.
For example, the situation shown in Fig. 6 and Fig. 7, last 4 bits are used to refer to the DRX additional cycle in the 2nd byte of additional DRX order, so represent different values corresponding to the length of long or short DRX cycle respectively in conjunction with the 4th bit information position.
Illustrate as follows, suppose the additional DRX order indication short period, and 4 bit indications 0001 of back, if from 0000 open numbering, then lack the sf5 in the DRX cycle (shortDRX-Cycle) below the correspondence, if from 0001 open numbering, then lack the sf2 in the DRX cycle (shortDRX-Cycle) below the correspondence.Long DRX cycle skew (longDRX-CycleStartOffset) also is same method correspondence.Below provided the example of a short DRX cycle and the skew of long DRX cycle.
Need to prove, the DRX order that 1 bit in the obligate information position that utilizes connected state DRX order indicates eNB to send to UE is additional DRX order or the mode of connected state DRX order, can also on the basis of original connected state DRX order, directly expand and obtain, for example can use new LCID completely newly to construct an additional DRX order, make and aforesaid way are similar, do not give unnecessary details herein.
After UE received additional DRX order, UE entered sleep state immediately, and just the next subframe from current subframe begins to enter sleep state.And after the DRX cycle of additional DRX order indication was carried out end, UE was waken up and still returns to original connected state DRX mechanism:
Namely for the UE that carries out single DRX, if this UE does not dispose the DRX parameter before receiving additional DRX order, then still get back to the state that does not have connected state DRX mechanism; If this UE receives dispose the DRX parameter before the additional DRX order but be not activated connected state DRX mechanism, then still returned to the state that is not activated connected state DRX mechanism; If this UE has disposed the DRX parameter and has started connected state DRX mechanism before receiving additional DRX order, then still return to original connected state DRX mechanism, namely carry out sleep state according to the DRX parameter of original connected state DRX mechanism.
Namely for the UE that carries out repeatedly DRX, if this UE receives disposed the DRX parameter before the additional DRX order but be not activated connected state DRX mechanism, then still return to the state that is not activated connected state DRX mechanism.Of particular note, do not dispose the DRX parameter if carry out the UE of the DRX that repeatedly optimizes, then can't carry out the DRX that repeatedly optimizes, because there is not the timer of duration timer for example etc., UE does not know when begin to enter sleep.And, if this UE has disposed the DRX parameter and started connected state DRX mechanism before receiving additional DRX order, do not carry out the DRX that repeatedly optimizes yet, produce conflict with DRX and the original connected state DRX mechanism of avoiding optimizing.
This shows, the method of the DRX of the embodiment of the invention can solve UE can't enter dormant problem in state of activation in the free time in the stage faster, make under the prerequisite of the existing DRX configuration that does not change UE, do not have the segment of packet transmission or reception to pass through the new sleep pattern of triggering execution that additional DRX orders in free time at UE, thereby UE economize on electricity more.
