Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment that obtains, belong to the scope of protection of the invention.
One embodiment of the invention provides a kind of collocation method of DRX cycle, as shown in Figure 1, comprising:
101, terminal record is at every turn from receiving the situation of physical downlink control channel PDCCH data after dormant state enters activated state.
Wherein, the terminal record receives the situation of physical downlink control channel PDCCH data while from dormant state, entering activated state, comprise: statistics receives the first event times of PDCCH data when dormant state enters activated state, and the second event number of times that does not receive the PDCCH data when dormant state enters activated state.
PDCCH data described in the embodiment of the present invention, refer to that base station is via the downlink data transmission indication information of PDCCH to each terminal broadcasting.
102,, according to the described situation that receives the PDCCH data after activated state that enters from dormant state, adjust DRX cycle.
Wherein,, according to the described situation that receives the PDCCH data while from dormant state, entering activated state, adjust DRX cycle, comprising:, if described the first event times reaches the first thresholding, reduce current DRX cycle; , if described second event number of times reaches the second thresholding, increase current DRX cycle; If described the first event times does not reach the first thresholding, and described second event number of times do not reach the second thresholding, keeps current DRX cycle constant.
Concrete, as shown in Figure 9, DRX cycle comprises dormant state and activated state.Suppose that the first thresholding is that 10, the second thresholdings are 12.After each terminal entered activated state by dormant state, record received the situation of PDCCH data.If receive the PDCCH data, the first event times adds 1, if do not receive the PDCCH data, the second event number of times adds 1, can be clear and definite be that the fastest through 10 DRX cycles, the first event times can reach the first thresholding, the fastest through 12 DRX cycles, the second event number of times can reach the second thresholding; If the appearance of the first event and second event space is the longest through 21 DRX cycles, first or the second event number of times can reach respectively the first or second thresholding.As seen, in limited DRX cycle, must there is one in the first event and second event and reach thresholding.When the first event times arrives the first thresholding, reduce DRX cycle,, when the second event number of times arrives the second thresholding, increase DRX cycle, the DRX cycle (being DRX cycle 2) of an increase has been shown in Fig. 9.
According to the scheme flow process of foregoing description, when occurring that multi-service is concurrent, can be according to whether in activated state, receiving the PDCCH data, record the first event times and second event number of times,, when the first event times reaches the first thresholding, reduce DRX cycle, thereby guarantee the QOS requirement when traffic carrying capacity is more; , when the second event number of times reaches the second thresholding, increase DRX cycle, thereby reduce power consumption when traffic carrying capacity is less.
Further, terminal, except according to receiving the situation self adaptation adjustment DRX cycle of PDCCH data after dormant state enters activated state of counting on, can also be carried out the DRX parameter configuration according to the configuration of network side.For example, long in the buffering area residence time when the data of terminal of giving to be sent, base station can be by the DRX parameter of high-level signaling configurating terminal, and concrete, high-level signaling is RLC(Radio Link Control, and wireless link is controlled) signaling of layer.Terminal can receive the DRX parameter that base station sends; The described DRX parameter of terminal applies, and the first event times and the zero clearing of second event number of times are also added up again, adopt the DRX parameter adaptive ground of base station configuration to carry out the DRX cycle adjustment.Wherein, described DRX parameter comprises the first thresholding, the second thresholding and/or DRX cycle, and described DRX parameter is determined by the scheduling time delay of the described base station data to be sent corresponding according to described terminal.Perhaps, terminal can also send to base station with the dump energy information of terminal, so that described base station sends the DRX parameter according to described dump energy information to described terminal; Wherein, described DRX parameter comprises the first thresholding, the second thresholding and/or DRX cycle.
The collocation method of the DRX cycle that the embodiment of the present invention provides, record enters the situation that receives the physical downlink control channel PDCCH data after activated state from dormant state, according to the first event times or second event number of times, reduce dynamically or increase current DRX cycle, the power consumption in meeting the process that QOS requires of having alleviated that the configuration mode of prior art DRX cycle causes is too high and reducing the long problem of time delay in the process of power consumption, realized more flexibly DRX mechanism, thus balance the QOS of multi-service when concurrent require and power consumption between relation.
Another embodiment of the present invention provides a kind of collocation method of DRX cycle, and as shown in Figure 2, the method comprises:
201, the scheduling time delay of base station to be sent data corresponding according to terminal or the dump energy information of described terminal are determined the DRX parameter; Wherein, described DRX parameter comprises at least a in the first thresholding, the second thresholding and DRX cycle.
Wherein, when terminal receives the DRX cycle of base station transmission, directly adopt this DRX cycle value to carry out discontinuous reception.Simultaneously, terminal, with the first event times and the zero clearing of second event number of times, restarts counting, then according to the first thresholding and second thresholding of base station configuration, carries out adaptive DRX cycle adjustment.Wherein, the first thresholding is used for reaching the first thresholding when terminal judges the first event times, reduces current DRX cycle; The second thresholding is used for reaching the second thresholding when terminal judges second event number of times, increases current DRX cycle; The first thresholding and the second thresholding also are used for not reaching the first thresholding when the first event times, and described second event number of times do not reach the second thresholding, and terminal keeps current DRX cycle constant.
In the present embodiment, the scheduling time delay of the data to be sent that base station can be corresponding according to terminal is determined the DRX parameter, also can determine the DRX parameter according to the dump energy information of terminal.
202, send described DRX parameter to described terminal, so that described terminal receives the situation of physical downlink control channel PDCCH data according to described DRX parameter and while from dormant state, entering activated state, adjust DRX cycle.
Wherein, terminal DRX parameter that base station is determined is as the foundation of carrying out the adjustment of self adaptation DRX cycle.
The DRX cycle collocation method that the embodiment of the present invention provides, determine the DRX parameter by the scheduling time delay of data to be sent corresponding to terminal or the dump energy information of terminal, can adjust on the basis of DRX cycle according to the situation self adaptation that receives the PDCCH data in terminal, further with reference to data and the terminal residual information about power of giving terminal to be sent, can avoid data delay, in conjunction with the actual conditions of terminal, save power consumption.
Another embodiment of the present invention provides a kind of collocation method of DRX cycle, as shown in Figure 3, comprising:
301, terminal enters activated state from dormant state.
Wherein, the DRX of terminal mechanism is for to change between dormant state and activated state according to DRX cycle.Terminal is not monitored PDCCH under dormant state, plays the effect of saving power consumption.Terminal monitoring PDCCH under activated state, receive the PDCCH data that base station sends.PDCCH data described in the embodiment of the present invention, refer to that base station is via the downlink data transmission indication information of PDCCH to each terminal broadcasting.
302, whether terminal receives the PDCCH data; , if receive the PDCCH data, perform step 303; , if do not receive the PDCCH data, perform step 306.
303, the first event times adds 1.
Wherein, the first event is terminal from receiving the event of PDCCH data after dormant state enters activated state.If terminal receives the PDCCH data after entering activated state at every turn, the first event times adds one so.
304, judge whether the first event times reaches the first thresholding; , if the first event times reaches the first thresholding, perform step 305; , if the first event times does not reach the first thresholding, perform step 309.
In the present embodiment, the first thresholding and the second thresholding can equate, also can not wait.
305, reduce current DRX cycle, with the first event times and the zero clearing of second event number of times.
After carrying out 305, return to 301.
For example, self adaptation DRX mechanism can comprise the optional DRX cycle value of n kind, if the value of the DRX cycle of base station and terminal is i kind wherein, the title system is in i state so, be denoted as Si(i=1,2 ... n), DRX cycle value corresponding to Si increases with the increase of i.Therefore, in this scene, system is in the S1 state and means that system is current and configured minimum DRX cycle, and be in Sn, means the current maximum DRX cycle that configured.In the present embodiment by judging whether the first event times arrives the first thresholding or second event number of times and whether arrive the second thresholding and decide the whether redirect of Si state of DRX.
Wherein, suppose that current end is at the Si state, Ti represents the DRX cycle length of current terminal, so: if terminal receives the PDCCH data after the dormancy bar enters activated state, the first event times (DecTimer) adds one so, if the first event times arrives the first thresholding (DEC), illustrating so that terminal has been waken up for DEC time has continuously all listened to data and needs to receive, illustrate that in observing time in the past, packet, than comparatively dense, need to reduce DRX cycle, just can better reduce time delay.So terminal by the Si state transition to the Si-1 state, because DRX cycle corresponding to Si-1 state is less than Si.
Further alternative, if during i=1, DRX cycle has been minimum, and when DecTimer arrival thresholding DEC, DRX cycle remains unchanged so.
306, the second event number of times adds 1.
Wherein, the second event number of times is terminal from not receiving the event times of PDCCH data after dormant state enters activated state.If terminal does not have data from receiving PDCCH after the dormancy bar enters activated state at every turn, the second event number of times adds one so.
307, judge whether the second event number of times reaches the second thresholding; , if the second event number of times reaches the second thresholding, perform step 308; , if the second event number of times does not reach the second thresholding, perform step 309.
308, increase current DRX cycle, with second event number of times and the first event times zero clearing.
After carrying out 308, return to 301.
For example, if terminal listens to PDCCH while from dormant state, entering activated state, data are not arranged, second event number of times (IncTimer) adds one so, if IncTimer arrives the second thresholding (INC), illustrate that so continuous wake up for INC time of terminal all do not receive the PDCCH data, illustrate that observing time, interior packet was fewer in the past, DRX cycle can increase, in order to better reduce power consumption, so terminal by the Si state transition to the Si+1 state, because DRX cycle Length Ratio Si corresponding to Si+1 state is large.
Optionally, during for i=n, DRX cycle has been maximum, even when DecTimer arrived thresholding DEC, DRX cycle remained unchanged.
309, keep current DRX cycle constant, return to step 301.
the collocation method of the DRX cycle that the embodiment of the present invention provides, record enters the situation that receives the PDCCH data after activated state from dormant state, according to the first event times or second event number of times, reduce dynamically or increase current DRX cycle, the power consumption in meeting the process that QOS requires of having alleviated that the configuration mode of prior art DRX cycle causes is too high, and in reducing the process of power consumption the long problem of time delay, and the DRX cycle value of plurality of optional is set, realized DRX mechanism more flexibly, thereby balance the QOS of multi-service when concurrent require and power consumption between relation.
Another embodiment of the present invention provides a kind of collocation method of DRX cycle, can also enter the buffering area mode of priority further combined with buffer status information, observe the buffer state in a period of time, be the time delay situation of the packet to terminal to be sent in buffering area, judge whether the DRX parameter of current operation meets the requirements.If undesirable, base station will notify high-level signaling to reconfigure the DRX parameter so.As shown in Figure 4, the method comprises:
401, when the terminal originating service request of data, the base station high level, according to the business QOS characteristic of terminal request, is set up service bearer, and according to the mapping relations of prior regulation, determines the DRX parameter.
Wherein, the DRX parameter comprises INC, DEC thresholding, current DRX cycle value and optional DRX cycle value.Optional DRX cycle value described here is the optional DRX cycle value of n kind mentioned above.In a kind of optional implementation, base station side can DRX parameter corresponding to pre-configured different business QOS difference.For example, DRX cycle corresponding to the business that QOS has relatively high expectations is shorter, and opposite QOS requires DRX cycle corresponding to lower business longer.
402, current buffer status information is detected in base station, according to buffer status information, judges whether the setting of current DRX parameter meets the QOS demand; Meet the QOS demand if current DRX parameter arranges, perform step 405; , if the setting of current DRX parameter does not meet the QOS demand, perform step 403.
Wherein, buffer status information can be that the buffer data average residence time that wraps in buffering area etc. can reflect the information of dispatching time delay, and perhaps the total amount of the current packet to be sent of buffering area etc. can reflect the state information of scheduling load.
Wherein, judge that according to buffer status information the method whether setting of current DRX parameter meets the QOS demand is: buffer status information and the decision threshold of high-rise definition are compared, judge whether buffer status information exceeds decision threshold, if not exceeding thresholding illustrates and arranges rationally, do not need to reconfigure the DRX parameter, continue to move under current DRX parameter configuration; Arrange unreasonablely if exceed thresholding illustrate, system will enter the buffering area mode of priority.For instance, the average residence time that buffer data is wrapped in buffering area is as buffer status information, and decision threshold is set to 90ms.If it is 80ms that buffer data wraps in the average residence time of buffering area, do not exceed decision threshold, think that the configuration of DRX parameter is rational; If buffer data wraps in the average residence time of buffering area more than 90ms, surpass decision threshold, show that packet is long at the average residence time of buffering area, overstocking appears in data, QOS can not meet the demands, and need to readjust the DRX parameter this moment, and DRX cycle is shortened, accelerate data processing speed, to meet the QOS demand.
403, the DRX parameter is readjusted in base station, and the DRX parameter after adjusting sends to terminal.
Wherein,, owing to determining in step 402 that current DRX parameter configuration is unreasonable, caused overstocking the problems such as overlong time such as the packet of buffering area, so base station can reconfigure the DRX parameter according to the direction that reduces DRX cycle by high level.
404, terminal is according to the DRX parameter operation that reconfigures self adaptation DRX mechanism shown in Figure 3.
Be understandable that, adjust DRX cycle at every turn or reconfigure other DRX parameters, terminal, all with the first event times and the zero clearing of second event number of times, restarts counting.
405, terminal continues operation self adaptation DRX mechanism shown in Figure 3 according to current DRX parameter.
When the dormant state overlong time of DRX cycle, the interval of adjacent twice activated state of terminal is elongated, and then may cause pending data to occur overstocking, thereby affect QOS, therefore the collocation method of the DRX cycle that provides of the embodiment of the present invention, judge according to buffer status information whether the setting of current DRX parameter meets QOS demand (can be specifically to judge whether the average residence time that buffer data wraps in buffering area exceeds decision threshold), if current DRX parameter does not meet QOS, base station is readjusted the DRX parameter and is configured to terminal, thereby avoids data delay.
Another embodiment of the present invention provides a kind of collocation method of DRX cycle, can also enter further combined with the dump energy of terminal the electric weight override mechanism.Electric weight override mechanism to the effect that terminal judges whether to need to adjust current DRX parameter according to terminal current residual electric weight, to reach the purpose of better reduction power consumption, by front about the analysis of self adaptation DRX mechanism as can be known, the first thresholding and two threshold values of the second thresholding are determining the tradeoff of power consumption and time delay, so in the electric weight mode of priority, the parameter configuration of modification also mainly refers to the first thresholding and two threshold values of the second thresholding.As shown in Figure 5, its flow process is as follows:
501, when terminal was initiated the data service request, base station sent DRX parameter corresponding to its business QOS that asks by descending RRC signaling to terminal.
For example, the DRX parameter can comprise optional DRX state number, DRX cycle value, INC and DEC threshold value that each state is corresponding.Optional DRX state number described here, can be with reference to the optional DRX cycle value of n kind mentioned above.
502, terminal detects the current residual information about power.
503, terminal judges whether to enter the electric weight mode of priority according to dump energy information; Enter the electric weight mode of priority during lower than certain value when dump energy, execution step 504; Otherwise, execution step 507.
Wherein, the electric weight mode of priority means that terminal will lose the service feature of a part and experience, and reduces power consumption, to exchange the service time of battery of longer time for.Because the DRX parameter is to require to be configured according to business QOS in advance, the Consideration of QOS comprises time delay, guarantees bit rate and packet loss etc., but low time delay high bit rate means the high power consumption of terminal,, so the DRX parameter configuration of electric weight mode of priority will preferentially submit to the principle that reduces power consumption, the service feature of sacrificing a part certainly will be experienced.Certainly, this adjustment is not the experience that immoderate, too poor performance not only has a strong impact on the user, and may not reach on the contrary the requirement that reduces power consumption., such as, the extra power consumption that causes the call duration time increase to bring because time delay is long, when emulation shows in the business data packet equispaced less than the 100ms left and right, increase power-dissipation-reduced that the unit time delay obtains than can be more obvious.
504, terminal is crossed uplink RRC (Radio Resource Control) signaling with the dump energy information exchange and is sent to base station.
505, modify to current DRX parameter according to described dump energy information in base station, and send to terminal.
Optionally, the step that in step 503, whether terminal judges enters the electric weight mode of priority also can transfer to by base station and carrying out, and that is to say that terminal sends to base station with dump energy information, by base station, according to dump energy information, determines whether to enter the electric weight mode of priority.
Wherein, need to pay the utmost attention to the parameter configuration that reduces power consumption in the electric weight mode of priority, for example, the adjustment of DRX parameter can be adopted the mechanism of dynamic mapping, and according to the difference of dump energy information, the amplitude that the first thresholding and the second thresholding are adjusted can be different, while as at electric weight, only remaining, being 10%, the amplitude of the first thresholding and the second thresholding adjustment is larger in the time of can being 20% than the dump energy residue, can save more power consumption like this, can realize the vernier control more meticulous to power consumption of terminal.
Concrete, following table has provided a kind of feasible dump energy and the mapping relations between the DRX parameter, and wherein B represents the dump energy of current terminal and the ratio of the total electric weight of battery, and INC represents the first thresholding, and DEC represents the second thresholding:
| Condition | Adjusted value |
