Description
Technical field
The present invention relates to wireless communication technology fields more particularly to a kind of data transfer control method, device and user to set
It is standby.
Background technique
UE (User Equipment, user equipment) in data transmission procedure, may by channel fading etc. influence and
It is abnormal, such as PDU (Protocol Data Unit, a protocol Data Unit) re-transmission reaches maximum times or receives mistake
State packet accidentally may make the disconnecting between UE and network side so as to cause inconsistent with the state of network side.In order to
Disconnecting is avoided, in the side UE, RLC (Radio Link Control, wireless spread-spectrum technology) layer can trigger reset process, by UE
The state of side and network side all resets to original state, guarantees that data transmission is normally carried out.
The RLC PDU that rlc layer generates first is put into caching, in the sending time slots that physical layer indicates by MAC (Media
Access Control, media access control) layer fetch from caching according to composition MAC PDU sent.It is resetted when UE is triggered
When, after network side handle reset process, data in caching will not be considered valid data by network side, therefore cache
Data should be removed.UE receives the reset confirmation of network, i.e. confirmation network performs reset process, and at this moment rlc layer can be sent out
Give one FLUSH message of MAC layer that the data in caching are all removed.
In the implementation of the present invention, inventor's discovery at least has the following technical problems in the prior art:
When the rlc layer of the side UE triggers reset, rlc layer stopping sends and receivees data, but MAC layer can also continue to send
Data in caching, the reset confirmation until receiving network side reply.Since RESET PDU is sent prior to AMD PDU, network
Side, which first receives RESET PDU, can first handle reset process, revert to original state, when the caching that the MAC layer for receiving the side UE is sent
When data, and reset can be triggered again, eventually lead to and unrecoverable error occur, and then data transmission link is caused to interrupt.
Summary of the invention

The third aspect, the present invention provide a kind of user equipment, and the user equipment includes above-mentioned data transfer controller.
Data transfer control method, device and user equipment provided in an embodiment of the present invention, when UE generation can restore to stagger the time,
So that UE is reached consistent with the state of network side as early as possible by resetting process, is removed in caching immediately once triggering resets process
Data, rather than just removed when the reset confirmation response until receiving network side reply, in avoiding to cache
Data are sent to network side and trigger unnecessary reset process and then data transmission link is caused to interrupt.
