Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of down buffer storage data reporting method.The present invention is gone back simultaneously
It is related to a kind of Radio Link Controller RLC.
Background technology
At present, RRC (the Radio Resource in LTE (Long Term Evolution, Long Term Evolution) system
Control, wireless heterogeneous networks) layer be UE (User Equipment, user equipment) be all configured with DRX (Discontinuous
Reception, discontinuous reception) function so that UE can discontinuously monitor PDCCH (Physical after DRX functions are opened
Downlink Control Channel, Physical Downlink Control Channel) channel, so as to reach the purpose of saving power for terminal.Opening
After DRX functions, UE determines whether to monitor PDCCH according to current DRX states, and performs corresponding data transmit-receive, and network side
(eNB, base station) then performs scheduling according to UE DRX states, and carries out corresponding data transmit-receive.
As the performance that emphasis promotes in the prior art instantly, DRX application spreads all over various scenes, and is used as saving power for terminal
An important measures and means, the process performance of equipment also turns into focus of attention under DRX, be particularly due to using DRX and
The additional transmissions time delay of appearance.
By taking prior art as an example, LTE protocol provides can be that the UE in " RRC_CONNECTED " state configures DRX functions.
One DRX cycle is made up of two parts：
1. during work (On Duration)
UE monitors PDCCH during this period, for receiving descending PDSCH (Physical Downlink Shared
Channel, Physical Downlink Shared Channel) data and uplink scheduling is obtained, carry out PUSCH (Physical Uplink Shared
Channel, Physical Uplink Shared Channel) transmission, belong to the DRX inactive phases；
2.DRX activates the phase
During this period UE can skip down channel reception come reach save electricity purpose.
ENB sides are by judging whether the UE comes into DRX, if UE is in the DRX phases, base station will be no longer to this
UE is scheduled；If during being in work, the normal consistency UE.
In current LTE system, the implementation process of scheduling is as follows：
1. receive the SDU of PDCP (Packet Data Convergence Protocol, PDCP) layer
(Service Data Unit, Service Data Unit), judges that UE is presently in chain surface location, if being BO to be refreshed
Layer, is no longer handled；If empty BO layers, user is moved into layer to be refreshed.
2. subframe is interrupted, chain top layer user to be refreshed is obtained, according to the strategy of poll, calculates UE BO information successively,
And it is assembled into message
3. chain top layer has had stepped through, or has met that RLC Up Date Bo Num are configured, BO information reportings are carried out.
In above flow, it is assumed that RLC once can only be to MAC (Media Access Control, medium access control)
The buffer data size of 50 users of dispatch notification, and number of network users is 100, wherein 50 users are in the DRX activation phases, separately
Outer 50 in the DRX work phases.Because RLC (Radio Link Control, wireless link control) does not consider DRX functions spy
Property, once report middle RLC to activate the reporting of user of phase downlink data caching in DRX for 50,50 are in DRX works in addition
The user for making the phase is not reported any downlink data caching, then at current time due to having at the user that downlink data caches
The phase is activated without being dispatched in DRX, although 50 users are in the DRX work phases in addition, because not having down buffer storage
Data, still it will not be scheduled, so as to which current time base station does not have any scheduling.So as to waste interface-free resources, increase
Propagation delay time.
As can be seen here, in the implementation process of LTE base station product, each UE down buffer storage data volume is by rlc layer
Notify to MAC layer scheduler.Typically by the way of periodically timing notifies, as TD-LTE commercialization and scale are expanded rapidly
Greatly, the UE numbers accessed in base station sharply increase, it is contemplated that influence of the information exchange frequent degree to properties of product, it will usually limit
RLC notifies the UE numbers to MAC scheduler down buffer storage data volumes in each cycle.In the case of DRX functions are not opened, by elder generation
The UE of all available for transmission data of order poll afterwards；But in the case of DRX functions are opened, if still according to sequencing
Poll, it is likely that cause to notify the UE of down buffer storage data volume to be in the DRX activation phases and can not dispatch, and the place that can be dispatched
Down buffer storage data volume the situation to MAC schedulers is not notified but in the UE of DRX inactive phases, so as to cause downlink data
