Abstract
The invention discloses a data processing method and a device. The data processing method comprises steps of removing a message header of received data on a radio link control (RLC) layer in a cluster communication system; recombining data whose message header is removed on the RLC layer; submitting the recombined data to a PDCP layer; and removing the message header of the received data on the PDCP layer and then submitting the data to an upper layer. According to the invention, a problem of abnormal packet loss during processing on the received data by a receiving end in the prior art is solved; and because repeated detection and reordering processing are not performed, abnormal packet loss is effectively avoided.
Description
Technical field
The present invention relates to the communications field, in particular to data processing method and device.
Background technology
Conventionally, as bottom packet loss, medium access control (Media Access Control, referred to as MAC)
Layer hybrid automatic repeat-request (Hybrid Automatic Repeat Request, referred to as HARQ) process, receiving terminal
Wireless spread-spectrum technology (Radio Link Control, referred to as RLC) and PDCP (Packet Data
Convergence Protocol, referred to as PDCP) data that receives of layer exist out of order and repeat, for ensure data sequentially,
Correct is delivered to upper strata, RLC and PDCP can carry out duplicate detection and process of reordering.To this end, transmitting terminal RLC,
PDCP is translation sequence SN in PDU, PDCP head, and receiving terminal RLC, PDCP are according to the SN of current data
Judge whether duplicate packages with paid-in SN and with SN, data resequenced.Specifically, transmitting terminal RLC
One state variable of entity maintaining is also added in PDU as SN value；Receiving terminal RLC entity is according to PDU
SN safeguards one group of state variable, is recorded by this group state variable and has been filed on data, data to be received, pending data
According to the SN scope waited, after receiving new packet, the SN of this packet is compared with this group state variable, completes
Duplicate detection, process of reordering, and update corresponding state variable.It is similar to, transmitting terminal and receiving terminal PDCP entity
Safeguard state variable simultaneously, complete duplicate detection, process of reordering by SN and state variable.As can be seen here, send
End needs with receiving terminal to ensure that state variable is consistent, if inconsistent, will cause the abnormal loss of packet.
Due to group service feature, in some scenarios, RLC, PDCP of receiving terminal and transmitting terminal there may be and differ
Cause.Such as, in trunked call, user can lag access calling, and now RLC and PDCP of user terminal is
Newly-built, its state variable is all initial value, and at the beginning of the state variable of RLC and PDCP of transmitting terminal base station is not necessarily
Initial value；When user is switched to Target cell, the state variable of terminal RLC entity is it cannot be guaranteed that consistent with Target cell；
When some abnormal conditions occurs, for ensureing that calling is normally carried out, base station by RLC and PDCP volume reconstruction, its state
Variable becomes initial value, and terminal cannot be known, now base station sends SN according to new state variable, and terminal is pressed
State variable before rebuilding according to base station RLC and PDCP receives, and may cause data-bag lost, and medium surface interrupts.
Process the problem that there is abnormal packet loss for the data to receiving of the receiving terminal in correlation technique, also do not propose effective
Solution.
