Description
Technical field
The present invention relates to wireless communication technology, particularly the LTE technology is a kind of method, network and user terminal of realizing variable discontinuous reception/discontinuous transmission (DRX/TX) cycle concretely.
Background technology
Stipulate in the 3-G (Generation Three mobile communication system) WCDMA 25304 v3.7.0 agreements, for reducing the power consumption under user terminal (UE) idle pulley, UE adopts discontinuous reception (DRX:DiscontinuousReception) under idle pulley, only need to monitor a PI (paging indication) in the calling time in each DRX cycle, and network side is when having beep-page message to send to UE, also correspondingly to the discontinuous transmission of UE (DTX:Discontinuous Transmitting) paging indicating message.The cycle of the DRX/DTX of UE (DRX CycleLength) is corresponding identical with network survey DRX/DTX cycle (DTX Cycle Length).UE monitors the paging indicator (PI) in the Page Indication Channel (PICH) when a DRX/DTX end cycle.If PI is 1, the expression network side has data flow to be handed down to UE, then wake UE up and receive the PCH frame, and to the PCH acquisition data of decoding.If PI is 0, the expression network side does not have data flow to be handed down to UE, and UE continues idle pulley.
UE can be attached to CS territory with specific DRX/DTX cycle and PS territory, and UE preserves the DPX cycle in CS territory and PS territory, and gets the shortest in CS territory and a PS territory DRX/DTX cycle and use.
The cycle of DRX/DTX is MAX=(2
k, PBP) frame.K is the DRX/DTX factor, can get 1,2,3,4,5,6,7,8, the some integers among the 9}, k can dispose in each territory.In circuit commutative field (CS territory), k passes through system message update; In packet-switched domain (PS territory), k is upgraded by Non-Access Stratum (NAS) process, if the NAS process does not provide the k value of negotiation, and the given DRX/DTX cycle of the equal using system message in UE and PS territory.PBP is a paging block periodicity, and PBP equals the repetition period of PICH, under fdd mode, and PBP=1.
But the division methods in this DRX/DTX cycle can not be applicable among the LTE that because cancelled the CS territory in the LTE network, if still use existing DRX/DTX cycle division methods, then the UE in the LTE network can only use a kind of DRX/DTX cycle of delimiting according to the PS territory.And can support multiple business in the LTE network, each professional activity characteristic is all different, and is also different for the demand of DRX/DTX.For example, the VoIP business for guaranteeing voice quality and professional real-time, can not be used long DRX/DTX in the voice data transmission process.And the online browsing business, it is not very high requiring for real-time, can use the long cycle to carry out the scheduling of data, can use long DRX/DTX.So for the LTE network, it is inappropriate using a kind of DRX/DTX cycle.
In the 50 the RAN2 meeting of LTE, the cycle of DRX/DTX is divided in proposition according to type of service in the LTE network, activate economize on electricity problem under (LTE_active) state to solve UE at LTE, and in 3GPP TR 25.813 V0.5.01TR, write LTE and under state of activation, support multiple DRX/DTX.
As shown in Figure 1, when UE sends Radio Resource control (RRC) connection request message to network side, that carries in this RRC connection request message sets up the type of service of having indicated UE to set up in reason (establishment cause) field; After network side is received RRC connection request message, send RRC and set up message, this RRC sets up message and includes the DRX/TX periodicity factor corresponding with type of service.After UE receives that RRC sets up message, store the DRX/DTX periodicity factor that this RRC sets up network side indication in the message.
Though such scheme has solved the shortcoming of having only a kind of DRX/DTX cycle in the LTE network.But in actual applications, this scheme still exists following shortcoming:
(1) UE need regularly monitor PICH in the blanking time between each session (session) of same business.
With the browsing page business is example, and it is exactly a session that the every click of user once links.After the user clicks a news links, network side issues data according to the professional corresponding DRX/DTX cycle of browsing page and flows to UE this locality, after UE received the data flow of this session according to the professional corresponding DRX/TX cycle of browsing page, the user read news always and does not initiate new session.After longer a period of time, the user clicks news links once more, and the data flow of carrying out new session transmits.The long period of time interval that has been separated by between twice session, and the time interval between session is unfixed.UE DRX/DTX cycle according to professional browse service correspondence in this time interval operates, and, when each DRX/DTX end cycle, monitors PICH that is, looks at whether network side has data flow to be handed down to UE.This mechanism of monitoring according to the DRX/DTX cycle on ground of solidifying is unfavorable for the UE economize on electricity.
(2) do not have concrete scheme can solve UE and move a plurality of business simultaneously.
Because when the user moves a plurality of business, after the RRC connection request message of network side according to UE, send RRC to UE and set up message, this RRC sets up message and includes a plurality of DRX/DTX periodicity factors corresponding with type of service, UE indicates all DRX/DTX periodicity factors to store network side, how not handle multiple business simultaneously but there is the corresponding techniques scheme to solve UE according to the DRX/DTX periodicity factor of storage, and the DRX/DTX cycle how dynamically to adjust UE and network side.
Summary of the invention

Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer,, the embodiment of the invention is described in further details below in conjunction with embodiment and accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as a limitation of the invention.
As shown in Figure 2, the DRX/DTX cycle that increases in paging channel (PCH) is adjusted the step factor field, adjusts in the step factor field in the DRX/DTX cycle of increase, the DRX/DTX cycle is set adjust step factor n.It is a variable that the DRX/DTX cycle is adjusted step factor n, and network side is according to the DRX/DTX periodicity factor of the value adjustment network side of n, and UE adjusts the DRX/DTX periodicity factor according to the value of n.N can get { 1,2,3 by network side being carried out the backstage configuration ..., certain integer among the 9}.
Because each professional corresponding DRX/DTX Periodic MA X (2 among the LTE
k, PBP) difference, and PBP=1 under the fdd mode, so corresponding DRX/DTX periodicity factor k of each professional DRX/DTX cycle.
Embodiment one:
As shown in Figure 3, when the user only moved a kind of business, network side adopted the DRX/DTX cycle of this business correspondence as the DRX/DTX cycle, and with the scheduled time of this DRX/DTX cycle as detection buffer (Buffer).Network side indicates professional corresponding DRX/DTX periodicity factor to UE.UE stores this DRX/DTX periodicity factor, with the DRX/DTX cycle of this DRX/DTX periodicity factor correspondence, as the DRX/DTX cycle of UE, receives the data flow that network side issues.
During with UE operation web page browsing business, the user clicks news links, carries out first session of network browsing business, if network side does not have data flow to send to UE, represents first conversation end.In time period before UE initiates another web page browsing business, network side is according to whether the data flow that is handed down to UE is arranged in the scheduled time detection buffer, if the scheduled time is when finishing, when not having in the buffer to send to the data flow of user terminal, network side and UE need enter a longer DRX '/DTX ' cycle.
At this moment, the network side startup DRX/DTX cycle is adjusted step factor n, according to formula k '=k+n, DRX/DTX periodicity factor k is adjusted into DTX ' periodicity factor k '; Soon the DRX/DTX cycle is adjusted into DRX '/DTX ' cycle.Simultaneously, network side also is set to DRX '/DTX ' cycle according to DRX '/DTX ' cycle with the scheduled time.Network side go up to send PI to UE at Page Indication Channel (PICH), wakes UE up and receives PCH, and UE decodes to the PCH frame and obtains the DRX/DTX cycle that PCH carries and adjust step factor n.UE is according to formula k '=k+n, and the DRX/DTX periodicity factor k of UE is adjusted into DRX '/DTX ' periodicity factor k '.Network side and UE enable DRX '/DTX ' cycle and DRX '/DTX ' Periodic MA X (2 simultaneously
K ', PBP).
Network side is according to adjusted scheduled time detection buffer, if still be not handed down to the data flow of UE in the buffer, network side is revised as DRX with the factor k ' of DRX '/DTX ' "/DTX " periodicity factor k ", k "=k '+n.Simultaneously, network side is still according to DRX "/DTX " scheduled time is set.Network side go up to send PI to UE at Page Indication Channel (PICH), wakes UE up and receives PCH, and UE decodes to the PCH frame and obtains the DRX/DTX cycle that PCH carries and adjust step factor n, and DRX '/DTX ' factor k ' of UE is revised as k ", k "=k '+n.Network side and UE enable new DRX "/DTX " Periodic MA X (2
K ", PBP).
When if network side detects buffer and finishes at the fixed time, the data flow that will not transmit always, then again to DRX "/DTX " cycle and (or/and) the network side scheduled time carries out recursion and revises, k reaches maximum 9 up to network side DRX/DTX periodicity factor, when equaling the k value of DRX/DTX periodicity factor under the LTE_IDLE state, network side is initiated state transition, and UE is moved to LTE idle condition (LTE_idle).
Embodiment two:
Be example with UE operation browsing page business still, the arbitrary value during the professional corresponding DRX/DTX cycle of network side-draw web page browsing arrives LTE_idle week is as the scheduled time of detection buffer.
After user and network side connected, network side indicated the professional corresponding DRX/DTX periodicity factor of browsing page to UE, and UE receives the data flow that network side issues according to the DRX/DTX cycle of this DRX/DTX periodicity factor correspondence.
Network side issues data flow according to the professional corresponding DRX/DTX cycle of web page browsing, and UE is according to DRX/DTX cycle receiving data stream.Network side detects the data that whether will send to UE in the buffer in addition according to the scheduled time.If have, network side continues to issue data according to the DRX/DTX cycle and gives UE, and UE received according to the DRX/DTX cycle; If no, the method that discloses according to embodiment one was dynamically adjusted the DRX/DTX cycle of UE and the DRX/DTX cycle of network side, and the scheduled time of network side remains unchanged.K reaches maximum 9 when the network side DRX/DTX factor, when equaling the k value of DRX/DTX periodicity factor under the LTE_IDLE state, that is, the DRX/DTX cycle of network side equals LTE_IDLE during the cycle, network side is initiated state transition, and UE is moved to LTE idle condition (LTE_idle).
To those skilled in the art, can carry out equivalent variations to the embodiment of the invention one or embodiment two.As, the increase DRX/DTX cycle is adjusted the step factor field in Radio Resource control (RRC) message; Network side sends the RRC signaling, and notice UE receives cycle adjustment step factor n in the RRC message, and the DRX/DTX cycle that UE acquisition RRC message is carried is adjusted step factor n.Again for example, network side sends 1/ layer of 2 (L1/L2) control of layer signaling signaling, and the DRX/DTX cycle in the running time-frequency resource of 1/ layer of 2 (L1/L2) control of notice UE receiving layer signaling scheduling is adjusted step factor n.
As shown in Figure 4, when UE moves multiple business simultaneously, network side all indicates each professional corresponding DRX/DTX periodicity factor to UE, UE stores the DRX/DTX periodicity factor of each type of service correspondence, select the DRX/DTX periodicity factor k of a minimum value as UE, with the DRX/DTX cycle in DRX/DTX cycle of this DRX/DTX periodicity factor correspondence, receive the data flow that network side issues as UE.But network side still issues data flow according to each professional corresponding DRX/DTX cycle.
Embodiment three:
VoIP business and the web page browsing business initiated simultaneously with the user are example, UE to the DRX/DTX periodicity factor of two kinds of business relatively after, select the DRX/DTX periodicity factor of the k value of the professional correspondence of VoIP as UE, then the DRX/DTX cycle of UE equals the DRX cycle of VoIP business.UE receives the data flow of two kinds of business that network side issues with the DRX/DTX cycle, and network side still issues data flow respectively according to two kinds of professional corresponding DRX/DTX cycles respectively.
As shown in Figure 5, select DRX/DTX cycle of VoIP business and the arbitrary value during LTE_idle week as the scheduled time when network side.Whether network side has the new data stream that is handed down to UE according to the scheduled time in the detection buffer, if having, UE continues to receive new data stream.If do not have, the network side startup DRX/DTX cycle is adjusted step factor n, adjust the DRX/DTX cycle of VoIP business, and on PICH, send PI to UE, wake UE up and receive PCH, UE decodes to the PCH frame and obtains the DRX/DTX cycle that PCH carries and adjust step factor n, but the scheduled time of network side is constant.The method that UE and network side disclose according to embodiment one, the DRX/DTX cycle of dynamically adjusting UE, network side was moved to the LTE_idle state with user terminal up to equaling LTE_idle during the cycle.
Embodiment four:
When network side adopts the DRX/DTX cycle of VoIP business as the scheduled time, if network side is according to the new data stream that does not send to UE in this scheduled time detection buffer, then expression needs to prolong the DRX/DTX cycle of network side transmission VoIP business and the DRX/DTX cycle of UE receiving data stream.The method that discloses according to embodiment one was then adjusted the DRX/DTX cycle of DRX/DTX cycle, the scheduled time and the UE of network side.Equal LTE_idle during the cycle when the DRX/DTX cycle of network side, network side is moved to the LTE_idle state with user terminal.
When a plurality of business of UE operation, if the professional kind of UE operation reduces, UE still adopts the current DRX/DTX cycle to receive the data that network side sends.For example, user terminal has moved the professional and web page browsing business of VoIP simultaneously, and when user terminal finished the VoIP business, UE still adopted the DRX/DTX cycle identical with VoIP to receive network side and issues data flow.The service operation because UE is through with, network side also no longer issues this professional data flow, state when this moment, network side and UE returned to a kind of business of operation, can be according to the method for embodiment one, embodiment two announcements, to DRX/DTX cycle, the scheduled time of network side, and the DRX/DTX cycle of UE adjust.
To those skilled in the art, the embodiment of the invention three or embodiment four also can carry out above-mentioned equivalent variations.As, the DRX/DTX cycle that increases in RRC message is adjusted the step factor field; Network side sends the RRC signaling, and notice UE receives cycle adjustment step factor n in the RRC message, and the DRX/DTX cycle that UE acquisition RRC message is carried is adjusted step factor n.Again for example, network side sends L1/L2 control signaling signaling, and the DRX/DTX cycle in the running time-frequency resource of notice UE reception L1/L2 control signaling scheduling is adjusted step factor n.
Though, among above-mentioned four embodiment of the present invention, adjust step factor n with the DRX/DTX cycle and adjust the factor, DRX/DTX Periodic MA X (2 as a kind of DRX/DTX cycle
k, PBP) the DRX/DTX periodicity factor k in adjusts.
But to those skilled in the art, this DRX/DTX cycle that is used to adjust the DRX/DTX cycle is adjusted step factor and also can carry out equivalent variations, as, by backstage configuration new DRX/DTX periodic variable or DRX/DTX cycle are set, directly the DRX/DTX cycle of network side are adjusted network side.The new DRX/DTX cycle can be by increasing by a DRX/DTX period field or increase the DRX/DTX period field in paging channel in RRC message, the new DRX/DTX cycle that will be provided with by RRC message or beep-page message is sent to UE.Perhaps UE receives network side and sends new DRX/DTX cycle in the running time-frequency resource that L1/L2 control signaling dispatches.
And the DRX/DTX cycle also can be sent to UE by RRC message or beep-page message with this DRX/DTX periodic variable by increasing DRX/DTX periodic variable field or increase DRX/DTX periodic variable field in RRC message in paging channel.Perhaps UE receives network side and sends DRX/DTX periodic variable in the running time-frequency resource that L1/L2 control signaling dispatches.In the LTE system, the value that the above-mentioned DRX/DTX cycle is adjusted step factor, DRX/DTX cycle, DRX/DTX periodic variable also can be configured according to the flow of data flow by base station (ENB:E-Node B).
Beneficial effect of the present invention is that in the LTE network, network side starts network side and the DRX/DTX cycle of UE and the dynamic adjustment in DRX/DTX cycle according to the data flow that sends to UE in the setting-up time detection buffer, reduces the number of times of UE monitoring to PICH; Reduced UE and monitored the power consumption that causes because solidify; Also solved UE and how to have moved under multiple business and the operation multiple business state dynamic adjustment simultaneously the DRX/DTX cycle of the DRX/DTX cycle of UE and network side.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiments of the invention; and be not intended to limit the scope of the invention; within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
