Abstract
The invention discloses a base station and a discontinuous reception and disposal method thereof. The method comprises the following steps: firstly, when the discontinuous reception (DRX) state of a to-be-maintained terminal is in the DRX dormant state, a scheduling request (SR) sent from the terminal is scheduled after being received; secondly, the actual DRX state of the terminal is judged within a preset period of time; thirdly, according to the judgment result of the above step, the DRX state of the terminal is adjusted and maintained; fourthly, according to the adjusted DRX state of the terminal, a corresponding scheduling behavior is conducted on the terminal. In this way, the influence of the SR virtual detection condition at a base station can be effectively eliminated during the DRX configuration process, so that the DRX state is kept the same with the maintenance of UE. The occurrence of packet loss due to the inconsistency of DRX states can be reduced. Meanwhile, the normal SR scheduling treatment is not affected at all.
Description
Technical field
The present invention relates to technical field of digital mobile communication, more particularly to a kind of base station and its carry out discontinuous connecing
Receiving processing method.
Background technology
In 3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, referred to as LTE) system, it is section
The battery consumption of user equipment (User Equipment, referred to as UE, also referred to as terminal) is saved, system is matched somebody with somebody
Discontinuous reception (Discontinuous Reception, referred to as DRX) function is put.DRX can make
UE stops monitoring Physical Downlink Control Channel (Physical Downlink Control within a certain period of time
Channel, referred to as PDCCH).
Fig. 1 shows the basic functional principle of DRX, in a DRX cycle (DRX Cycle) has work
Dynamic time (Active Time) and dormancy time (Sleeping Time), when being configured with DRX, UE is only
In activity time monitoring C-RNTI (Cell Radio Network Temporary Identifier/Identity, Cell-RNTI), TPC-PUCCH-RNTI (physics
Ascending control channel TPC command is identified), (Physical Uplink Shared Channel TPC is ordered TPC-PUSCH-RNTI
Order mark) and Semi-Persistent Scheduling C-RNTI (semi-persistent scheduling cell-radio network is interim
Mark) PDCCH that scrambles.
OnDuration Timer (duration timer) define UE when DRX cycle starts to be needed continuously
Monitor the number of subframes of PDCCH.
DRX InactivityTimer (the static timers of DRX) define UE and receive under instruction new biography data
After row control information (Downlink Control Information, abbreviation DCI), in addition it is also necessary to continue continuous monitoring
The number of subframes of PDCCH.
When DRX is configured with, the activity time of UE includes duration timer or DRX
Time when InactivityTimer or DRX retransmission timers or contention resolved timer run；And scheduling please
The time for asking (Scheduling Request, abbreviation SR) to be suspended；And HARQ (Hybrid Automatic
Repeat request, hybrid automatic repeat-request) retransmit the time that distribution uplink authorization may occur；And UE
After being properly received accidental access response message, the C-RNTI that PDCCH indicates to have for UE is not yet received
Or the time of the new transmission of interim C-RNTI.
When UE needs upload data to be used for transmitting without ascending resource, UE can be by SR to base station
By detecting the SR for receiving, request ascending resource, base station judge whether UE has resource requirement, Jin Erxiang
UE sends uplink authorization.UE can also send SR in DRX dormancy times, wait uplink authorization when
Between, UE enters the activity time.
When being configured with DRX, base station side will also safeguard the DRX states of UE, when base station judges that UE is in
During inactive time, the UE will not be dispatched, only when UE being judged in the activity time, can just dispatch UE.
Do not limited by DRX states as UE sends SR, SR will also be detected in UE inactive times in base station,
If detecting SR, then it is assumed that UE enters the activity time, UE uplink authorizations are given, send DCI0, and root
According to DRX state normal consistencies UE of UE.
Due to the complexity of wireless environment, often there is the situation of the empty inspections of SR, i.e. UE does not send SR,
But base station detects SR due to the reason mistake such as interference of wireless environment.When base station is in DRX Working moulds
Empty inspection SR under formula, it is inconsistent with UE sides DRX states to will result in base station side, and then it is different Radio Link occur
Often the problems such as.For example, base station empty inspection SR under DRX resting states, will start DRX
InactivityTimer, into DRX active states, and UE actual DRX states or dormant state.This
When, if base station carries out downlink data transmission, UE is not due to detecting PDCCH, therefore cannot receive, and makes
Into packet loss, or even because the descending maximum retransmission that reaches causes abnormal call drop.

Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that obtained, belong to the scope of protection of the invention.
Embodiment one
The embodiment of the present invention provides a kind of discontinuous reception processing method of base station, is applied to base station side, such as Fig. 2
Shown, methods described comprises the steps：
Step S201, when the DRX states of the terminal safeguarded are DRX resting states, receives the end
Dispatch request SR at end；
Step S202, is scheduled to the SR, and setting time period in, the reality to the terminal
Border DRX states make decisions, according to the DRX states of the terminal of court verdict adjustment and maintenance, and
Corresponding scheduling behavior is taken according to the DRX states after adjustment to the terminal.
When implementing, start pre-set SR judgement timer, by safeguard the terminal state
It is revised as DRX SR judgement states；And under timing constraint, be to stop to the DRX states of the terminal
Dormancy state or state of activation make decisions.
Wherein, SR judgements timer acts on and is：Be indicated under DRX resting states, detect SR but
A period of time of the whether empty inspections of SR is not confirmed.SR is only dispatched in this period, is not carried out other scheduling, is kept away
Exempt from base station and enter DRX activated states in advance, it is inconsistent with the DRX states that UE sides are safeguarded, cause packet loss.
The timing length of the SR judgements timer is preferably from base station to receive SR and SR and dispatch and reaches most
Duration between last DCI0 re-transmission of big number of retransmissions.
Further, in the embodiment of the present invention, it is contemplated that base station dispatcher knows the DRX configuration parameter of UE,
Can be configured according to DRX and UE up-downgoing dispatch situations, calculate DRX associated timers operation shape
Condition.So, in the embodiment of the present invention, under timing constraint, it is preferable that according to terminal uplink CRC result
Feedback and base station side safeguard the terminal DRX associated timers ruuning situation, with reference to dormancy
The condition that state and state of activation should meet, makes decisions to the DRX states of the terminal.
In one particular embodiment of the present invention, process is made decisions to the DRX states of terminal specific as follows：
When SR judgement timers are not timed-out, judge whether to receive the correct upstream datas of CRC；
If receiving the correct upstream datas of CRC, stop the SR judgements timer, and judge whether
Have arbitrary DRX associated timers for meeting terminal state of activation operation, if so, then judge the terminal as
DRX states of activation；Otherwise, it is determined that the terminal is DRX resting states；
If being not received by the correct upstream datas of CRC, just judging whether DRX duration timers
In operation and run duration has new biography to dispatch, if so, then stop SR judgement timer, judge the end
Hold as DRX states of activation；Otherwise, the above-mentioned deterministic process of repetition, until the SR timer expiries；
When the SR adjudicates timer expiry, current whether only DRX InactivityTimer operations are judged,
If it is, stopping DRX InactivityTimer, judge that the terminal is DRX resting states；Otherwise,
Judge that the terminal is DRX states of activation.
Further, in the embodiment of the present invention, when the DRX states in the terminal safeguarded are sentenced for DRX SR
Certainly during state, if receiving the SR of the terminal, the SR is scheduled, and restarts the SR
Judgement timer, and under the timing constraint, the DRX states of the terminal are still activated for resting state
State makes decisions, according to the DRX states of the terminal of court verdict adjustment and maintenance, and according to adjustment
DRX states afterwards are dispatched behavior accordingly.
In summary, the invention provides a kind of scheme of reception discontinuous in the mobile communication network, makes base
Stand and can either ensure the scheduling of normal SR, again can be under the scene of the empty inspections of SR, it is ensured that base station and UE DRX
The uniformity of state.When UE is configured with DRX, effectively reduces base station and the DRX states of UE are inconsistent
Problem, and then reduce the generation of packet loss.
Embodiment two
The embodiment of the present invention provides a kind of discontinuous reception processing method of base station, and which passes through to disclose more skills
Art details, is described in detail to one methods described of embodiment.
In the implementation, base station dispatcher knows the DRX configuration parameter of UE, can according to DRX configure with
And UE up-downgoing dispatch situations, DRX associated timer operation conditions is calculated, and whether knows UE
In the DRX activity times.Scheduler needs to safeguard each UE for being configured with DRX one SR judgement
Timer, SR judgement timers start when base station receives the SR of the UE in DRX resting states.
SR adjudicates timer run duration, if being received again by the SR of UE, restarts the timer.The SR sentences
Stop when certainly meeting the stop condition of setting.Wherein, stop condition includes：1) end of run terminates；2)
Stop when receiving the CRC correct results of upstream data；3) OnDuration Timer run and period has
Stop when new biography is dispatched.
Based on above-mentioned configuration, if base station is when DRX dormant states detect SR, to UE uplink authorizations, send out
DCI0 is sent, and starts SR judgement timers.If SR is not empty inspection, after UE sends SR, can enter
DRX activated states, wait DCI0 to be received, and after receiving, UE can send upstream data, if detecting after base station
It is correct to upstream data CRC (CRC), illustrate that SR is that UE truly sends, now
Stop SR judgement timers, DRX states judged according to the operation of other DRX timers, can keep with
UE safeguards side the uniformity of DRX states.If SR judgement timers run to overtime termination, illustrate in SR
After scheduling reaches maximum retransmission, the correct upstream datas of CRC are all not detected by, then it is assumed that SR is very
Possibly empty inspection, also, UE is in a dormant state, and such UE will not detect DCI0 and concurrently serve row
Data.If now base station side only InactivityTimer operations, illustrate UE also in DRX dormant states,
InactivityTimer is started after base station scheduling void examines SR, and UE can't detect DCI0 in dormant state,
InactivityTimer will not be started, now base station side needs to stop InactivityTimer, and the UE states are put
For DRX resting states, keep and UE sides DRX state consistencies.If SR adjudicates timer run duration,
OndurationTimer starts, and now UE can also enter DRX activated states, and new biography can be dispatched in base station, such as
There is new biography to dispatch, then stop SR judgement timers, and ensured and UE by other DRX timers operations
Safeguard DRX state consistencies.
Enforcement to the present embodiment methods described is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 3, the flow chart for carrying out discontinuous reception process in a sub- frame in for base station.Base station pair
Which kind of scheduling behavior UE takes, and needs to judge the DRX states that the UE for safeguarding is presently in first, bag
Include following three kinds of states：DRX states of activation, DRX resting states and DRX SR judgement state.
Secondly, the different DRX states according to the UE for safeguarding are into different handling processes, concrete to process
Difference is as follows：
The DRX states of the current UE for safeguarding are DRX states of activation：Normal consistency UE.
The DRX states of the current UE for safeguarding are DRX resting states：Judge whether to receive SR, if received
To SR, SR is scheduled, and starts SR judgement timers, modification UE states are adjudicated for DRX SR
State；If not receiving SR, UE is not dispatched.
The DRX states of the current UE for safeguarding are that DRX SR adjudicate state：Timer is adjudicated according to SR is
No time-out is made decisions to the actual DRX states of UE.
Wherein, whether time-out is made decisions specifically to the actual DRX states of UE to adjudicate timer according to SR
It is as follows：
If-SR timer expiries, current whether only DRX InactivityTimer operations are judged,
If it is, stopping DRX InactivityTimer, the DRX states for changing the UE for safeguarding are DRX dormancy
State；Otherwise, the DRX states for changing UE are DRX states of activation.
If-SR timers are not timed-out, judge whether to receive the correct upstream datas of CRC, enter
Row is following to be processed：
-- if the correct upstream datas of CRC are received, is stopped SR judgement timers, and is judged whether
There are arbitrary DRX timers for meeting UE activated states in operation, if it is, the DRX states of modification UE are
DRX states of activation；Otherwise, the DRX states for changing UE are DRX resting states.
-- if the correct upstream datas of CRC are not received by, are judged whether in OnDurationTimer
Run duration has new biography to dispatch, if it is, stopping SR judgement timers, the DRX states for changing UE are
DRX activated states；Otherwise, SR judgement states are kept, SR new biographies and re-transmission can only be dispatched, it is impossible to carry out which
It dispatches.
Generally speaking, base station passes through to judge the DRX states residing for UE, to determine which kind of is taken to UE
Scheduling behavior.Scheduling behavior to UE under three kinds of states is respectively：
1) DRX states of activation, up-downgoing can normal consistencies.
2) DRX resting states, up-downgoing are not dispatched.
3) DRX SR judgements state, descending not dispatch UE, the up new biography that dispatch SR and re-transmission.
Further, in the present embodiment, the ruuning situation of timer is adjudicated according to SR, and UE is in DRX
The condition of state of activation, further, the Rule of judgment of three kinds of DRX states proposed by the present invention is as follows：
1) condition in DRX states of activation is：A) OnDuration Timer or DRX retransmission timers
Or the time during operation of contention resolved timer；B) InactivityTimer runs and SR judgement timers do not have
There is the time of operation；C) time of ascending HARQ retransfer scheduling；D) accidental access response is sent, to head
The time of individual new biography DCI.
2) condition for adjudicating state in DRX SR is：SR judgement timer operations and OnDuration
Time when Timer or DRX retransmission timers or contention resolved timer all do not run；
3) condition in DRX resting states is：After DRX starts, both the above state is not belonging to
UE is in dormant state.
As shown in figure 4, the transition figure of the three kinds of DRX states realized for the method for the invention.Can from figure
To see, the condition of three kinds of State Transferrings is：
1) activated state is converted to dormant state：The condition in activated state required in no longer meeting agreement.
2) dormant state is converted to activated state：OndurationTimer starts.
3) dormant state is converted to SR judgement states：Receive SR.
4) SR judgements state is converted to dormant state：SR judgement timer expiries stop, and do not have other to meet
The timer operation of UE activated states, or only DRX InactivityTimer operations；Or just receive CRC
Stop SR judgement timers after true upstream data, and do not have other to meet the operation of the timer of UE activated states.
5) SR judgements state is converted to activated state：The correct upstream datas of CRC are received, and has arbitrary satisfaction
The timer operation of UE activated states；Or SR judgement timer run durations, OndurationTimer startups.
6) activated state is converted to SR judgement states：OndurationTimer runs abort after starting, and SR sentences
Certainly timer is currently running.
For clearer explanation embodiments of the invention process, a concrete application of the present invention is given below
Example, as shown in figure 5, for the sequential chart of this application example, in figure：
Moment (1), UE are in DRX resting states, now detect SR, and dispatch SR, now open
Dynamic SR adjudicates timer, adjudicates state into SR.
At the moment (2), the DCI0 to SR uplink authorizations is issued, start InactivityTimer.
At the moment (3), on the corresponding running time-frequency resources of DCI0 of uplink authorization, it is correct that base station receives CRC
Uplink transmission data, illustrate that SR is not empty inspection, stop SR judgement timer, due to now
InactivityTimer is running, into DRX states of activation.
At the moment (4), InactivityTimer runs abort, and enters DRX resting states from DRX states of activation.
Moment (5), UE are in DRX resting states, and now empty inspection is not aware that to SR, now base station
SR is empty inspection, dispatches SR, starts SR judgement timers, adjudicates state into SR.
At the moment (6), the DCI0 to SR uplink authorizations is issued, start InactivityTimer.Due to UE simultaneously
SR is not sent out, DRX dormant states are constantly in, DCI0 is can't detect, therefore base station does not receive always
The correct upstream datas of CRC.
Moment (7), SR judgement timer operation time-out terminate, now only InactivityTimer operations,
Stop InactivityTimer timers, DRX resting states are entered from SR judgement states.
Between moment (1) and (3), state is adjudicated in SR, can only dispatch SR, it is impossible to carry out which
Its new biography is dispatched.
Between moment (3) and (4), in DRX states of activation, UE can be dispatched.
Between moment (5) and (7), state is adjudicated in SR, can only dispatch SR, it is impossible to carry out which
Its new biography is dispatched.
In sum, it is known that the UE to being configured with DRX of the invention, the DRX shapes of UE are safeguarded in base station side
State, and according to DRX states, be scheduled.Up-downgoing is made to dispatch DCI, can be movable in UE DRX
Time issues.The present invention adjudicates state by DRX SR, and whether indicate from SR is received to SR is confirmed is empty
A period of time between inspection, during this period of time, UE can only uplink scheduling SR, it is impossible to carry out other scheduling,
Until judging that SR is not empty inspection, or start the DRX for ensureing UE by timers such as OndurationTimer
During state of activation, could normal consistency.
The present invention is effectively guaranteed when DRX is configured, and base station can exclude the impact of the empty inspections of SR, keep
DRX states are consistent with the maintenance of UE sides, reduce the packet loss caused because DRX states are inconsistent and occur.Meanwhile,
Normal SR dispatch deals are not affected.
