Specific embodiment
In order to solve the problems, such as that unlatching CDRX function existing in the prior art causes data transmission quality to decline, the present invention
Process is executed to the CDRX of existing scheme in embodiment to be studied in detail.
Existing CDRX implementation procedure is introduced first.
CDRX implementation procedure is exactly so that terminal is entered DRX dormant period when no data are transmitted, and have data to need to transmit
When reenter DRX activation the phase, to reduce the process of power consumption of terminal.Terminal receives the radio resource control that base station issues
After (Radio Resource Control, RRC) reconfiguration message, CDRX parameter is read, then terminal is according to established rule, week
PDCCH is monitored to phase property, for only configuring the CDRX implementation procedure in a CDRX period, CDRX parameter includes:
On Duration Timer: Active Timer, when starting which specify each CDRX period, terminal is persistently monitored
PDCCH number of sub frames.
DRX Inactivity Timer: discontinuous reception inactivity timer works as end which specify during the activation phase
After the PDCCH that an instruction upstream and downstream user data just pass is successfully decoded in end, it is continuously in continuous P DCCH of DRX activation phase
Frame number.
DRX Retransmission Timer: discontinuous reception retransmission timer, which specify receive from terminal expectation
The subframe (after HARQ RTT Timer time-out) that downlink retransmits starts, the PDCCH number of sub frames continuously monitored.
HARQ RTT Timer:HARQ return interval timer, allowing terminal, a downlink transfer is counted in the past, is continued
After the duration of the timer, the re-transmission of downlink is just begun listening for.When HARQ RTT timer time-out, and corresponding HARQ instance process connects
When the data received are not successfully decoded, terminal can be one DRX-Retransmission of the HARQ process initiation
Timer.When DRX-Retransmission Timer operation, terminal can monitor the PDCCH retransmitted for HARQ.
In the longDRX-Cycle:CDRX period, which specify a CDRX periods to account for how many a subframes.
DrxStartOffset: the starting subframe in CDRX period is specified.
If current System Frame Number (System Frame Number, SFN) meets following formula:
[(SFN*10)+subframe number] modulo (longDRX-Cycle)=drxStartOffset
Terminal starts On Duration Timer, begins listening for PDCCH:
During On Duration Timer operation, if terminal does not receive what instruction upstream and downstream user data just passed
PDCCH stops PDCCH blind examination then entering DRX dormant period between terminal after On Duration Timer end of run,
Until next CDRX period opens.
During On Duration Timer operation, if terminal receives what instruction upstream and downstream user data just passed
PDCCH, terminal will start DRX Inactivity Timer, each downlink subframe during timer operation is monitored
PDCCH.When receiving a scheduling information (PDCCH that instruction just passes) during DRX Inactivity Timer operation, terminal
The timer can be restarted.After the timer expiry, terminal can just enter DRX dormant period.
Under normal circumstances, under the premise of CDRX parameter configuration is reasonable, quality of service can guaranteed by opening CDRX function
Under the premise of reduce terminal power consumption levels.But when terminal channel quality is very poor, continuing starting CDRX function can not only be made
It can also be greatly reduced at the decline of downstream transmission quality, and at this time by CDRX function bring power consumption gain.
However in existing scheme, base station configures CDRX parameter according to the business feature of carrying, and passes through RRC reallocation message
CDRX parameter is handed down to terminal, i.e. base station data packet characteristic that business is only considered when carrying out CDRX parameter configuration, it can't
Consider the state for being configured terminal: such as terminal is presently in the channel quality etc. of position.And under CDRX parameter is once configure
It goes, terminal will execute CDRX function according to the CDRX parameter that base station provides.
It is found in actual test, when terminal is in cell edge weak signal overlay area, after CDRX function is opened in base station, phase
Compared with the scene for not opening CDRX function, data transmission quality can be declined, and the probability that uplink and downlink data retransmit also can be more
Greatly, i.e., CDRX function being opened under weak covering may bring a negative impact, and channel quality is poorer, and this negative effect is more serious.
Such as under scene that is very poor in a certain channel quality and opening CDRX function, base station is in Active Timer On Duration
The last one subframe of Timer operation has issued the PDCCH that indicating downlink user data just passes, but terminal is due to channel quality
It is too poor and lose the subframe or decoding error without receiving the instruction of this down user data, then the terminal is at this time
It not will start discontinuous reception inactivity timer DRX Inactivity Timer, but be directly entered DRX dormant period, cause
Base station enters different DRX states from terminal:
Base station thinks that terminal is still within the DRX activation phase, so it is automatic to carry out downlink data mixing according to normal flow
The scheduling of retransmission request (Hybrid Automatic Repeat Request, HARQ) process；In fact, terminal is at this time
DRX dormant period is entered, will not continue to monitor PDCCH, retransmits it is possible that will cause continuous leakage and receive base station, will lead to when serious
Entire HARQ process transmission failure.
Base station is not only resulted in so constantly to be retransmitted, the resource of control channel is occupied, but also will cause serious
Downlink data packet loss.And under the scene for not opening CDRX function, even if terminal leakage has been received under a certain first biography of time slot instruction
The PDCCH of row user data, also can be by continuing to restore HARQ process and re-transmission, to avoid entire downlink data HARQ
The transmission of process fails.
And for transmitting uplink data, after terminal enters DRX dormant period, base station, which can be suspended to terminal, issues new number
According to uplink authorization, until DRX next time activates the phase that can just dispatch new transmitting uplink data.Therefore, if terminal is in letter
Condition very poor covering point in road opens CDRX function again simultaneously, when terminal causes uplink retransmission to become more since channel condition is poor
Afterwards, due to the unlatching of CDRX function, the data packet newly arrived cannot be transmitted in time: will lead to terminal uplink data packet in this way
Accumulation, causes data transfer delay, also results in and activates final end to need to apply more resource blocks in subsequent DRX to transmit
Upstream data.But the uplink transmission power of terminal be it is limited, terminal can be such that data pass because uplink transmission power is limited
Defeated degree of reliability decline, causes the probability of base station successful data reception to reduce, so as to cause uplink channel transmission quality into one
Step deteriorates.
There are also a kind of scenes being likely to occur: if rear several subframes of the base station in the DRX activation phase have issued instruction uplink
The PDCCH that user data just passes, at this point, the channel quality due to terminal is very poor, terminal is possible to that the PDCCH subframe can be lost,
So terminal can enter DRX dormant period because base station is dispatched without new data, but base station is not aware that lost terminal at this time
The PDCCH subframe still in defined downlink subframe feeding back ACK/NACK and can issue retransmission resource instruction, and terminal at this time
Due to coming into DRX dormant period, so this part of PDCCH subframe will not be received, until next time terminal swashs into DRX
Current, under worst case, terminal can just monitor again PDCCH until next CDRX period.
Based on above-mentioned analysis, the embodiment of the invention provides a kind of control programs of discontinuous reception.In the technical solution,
When starting by the CDRX period indicated in network side, the parameter value of characterization terminal present channel quality is obtained, when the parameter value
When greater than pre-set first threshold value, extend the listening period in the CDRX period to PDCCH, so that poor in channel condition
When, it is capable of the execution process of reasonably optimizing CDRX function, extends the time that terminal monitors PDCCH in the CDRX period, therefore
Can reduce as channel condition is poor and caused by terminal and network side the probability of CDRX step-out phenomenon occurs, while can also drop
The number that data retransmit occurs for low terminal, to achieve the purpose that promote data transmission quality.
The embodiment of the present invention is illustrated below in conjunction with Figure of description, it should be understood that implementation described herein
Example is merely to illustrate and explain the present invention, and is not intended to restrict the invention.And in the absence of conflict, the reality in the present invention
The feature for applying example and embodiment can be combined with each other.

Cheng Tu, specifically include the following steps:
Step 12, when starting in the CDRX period of network side instruction, the parameter value of characterization terminal present channel quality is obtained；
Wherein, as long as the parameter value can characterize terminal present channel quality, it can be, but not limited to connecing for terminal
Receive the re-transmission ratio data in signal strength or terminal current buffer data to be sent.
Step 22, when the parameter value is greater than pre-set first threshold value, extend the prison in the CDRX period to PDCCH
Listen the time.
Specifically, the listening period of PDCCH can be specifically included by extending in the CDRX period:
1, it is greater than the first threshold value in the parameter value and is less than pre-set second threshold value, and terminal is in On
Duration Timer does not receive the PDCCH that instruction upstream and downstream user data just pass during running when, in On Duration
Start pre-set extension timer after Timer end of run, is persistently supervised during extension timer operation with instruction terminal
Listen PDCCH；
Optionally, the time span for extending timer can be with are as follows:
The sum of the time span of HARQ RTT Timer and DRX Retransmission Time.
Further, terminal is during extension timer operation, if at the beginning of terminal receives instruction upstream and downstream user data
When the PDCCH of biography, then start DRX Inactivity Timer according to existing procedure, each during timer operation
Downlink subframe monitors PDCCH；It is fixed in extension if terminal is not received by the PDCCH that instruction upstream and downstream user data just pass
When device end of run after be directly entered DRX dormant period.
2, when the parameter value is greater than the second threshold value, PDCCH is persistently monitored within the CDRX period.
PDCCH is persistently monitored within the CDRX period, that is to say, that terminal independently closes CDRX function.
In the embodiment of the present invention, when starting by the CDRX period indicated in network side, characterization terminal present channel is obtained
The parameter value of quality extends the monitoring in the CDRX period to PDCCH when the parameter value is greater than pre-set first threshold value
Time, so that capableing of the execution process of reasonably optimizing CDRX function when channel condition is poor, extending terminal in the CDRX period
The middle time for monitoring PDCCH, thus can reduce as channel condition is poor and caused by terminal and network side CDRX occur lose
The probability of phenomenon is walked, while terminal can also be reduced, the number that data retransmit occurs, promotes data transmission quality to reach
