Embodiment 1

[0129] Embodiment 1: Processing of the PDCP SDU data packet during the normal transmission process of the PDCP SDU data packet carried separately.

[0130] For the separated bearer of the UE, the aggregated base stations currently serving the separated bearer include the master base station and the secondary base station. At this time, it is assumed that the separate bearer of the UE is transmitted on the master base station and the secondary base station at the same time.

[0131] If the UE only supports downlink bearer separation, the PDCP entity in the master base station will send part of the PDCP SDUs of the UE's separate bearer to the RLC entity corresponding to the UE's separate bearer in the master base station for transmission according to the flow control technology. The other PDCP SDUs of the separated bearer are delivered to the RLC entity corresponding to the separated bearer of the UE in the secondary base station through the X2 interface for transmission.

Embodiment 2

[0135] Embodiment 2: processing of PDCP SDU data packets when the number of secondary base stations serving split bearers increases.

[0136] The master base station that provides services for the separated bearer sends an indication message for the addition of the secondary base station to the added secondary base station, and configures the resources of the added secondary base station for the UE through a radio resource control (Radio Resource Control, RRC) reconfiguration message. According to the RRC reconfiguration message, the UE allocates bearer resources of the added secondary base station, synchronizes with the added secondary base station, and feeds back a reconfiguration complete message to the master base station at the same time.

[0137] In the process of increasing the number of auxiliary base stations that provide services for the split bearer, the split bearer maintains the transmission process of the PDCP SDU data packet normally carried (see Embodiment 1 for...

Embodiment 3

[0139] Embodiment 3: processing of PDCP SDU data packets when the number of secondary base stations providing services for split bearers decreases.

[0140] The master base station or the secondary base station that provides services for the separated bearer triggers the deletion process of the secondary base station. In the secondary base station deletion process, the master base station notifies the UE to delete the corresponding secondary base station through an RRC reconfiguration message. The RRC reconfiguration message includes the separated bearer identifier. and carry information such as dedicated resources. According to the bearer admission status of the master base station, the separated bearers accepted by the master base station will be independently transmitted by the master base station (that is, the bearers are combined). The master base station performs the following processing on the accepted separated bearer: stop the transmission of the PDCP SDU data packets...

Abstract

The present invention provides a data packet processing method and device, which are used to solve the problem of how to deal with the PDCP SDU data packet of the separated bearer in the normal transmission process based on the bearer separation scenario, and when the auxiliary base station providing services for the separated bearer changes. The problem of separating and processing the PDCP SDU data packets carried by the separate carrier improves the work efficiency and resource utilization of the aggregation base station. The method of the present invention includes: determining the transmission information of each data packet in the data packet of the packet data convergence protocol PDCP service data unit SDU under the bearer separation scenario of the current transmission; according to the transmission information of each data packet, the Packets are processed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data packet processing method and device. Background technique [0002] With the rapid development of intelligent terminals and the increasing demand of users for data service transmission rate and capacity, the traditional macro base station single-layer coverage network can no longer meet the user's data service needs; To solve this problem, the technology and architecture of bearer split are introduced at the same time, so that the terminal can use the cell resources of multiple base stations at the same time, thereby enhancing the mobility management of the terminal and increasing the peak value of the terminal data service transmission rate. [0003] At present, for the processing of the separated bearer data packets, a packet data packet deletion timer is started for the packet data convergence protocol (PacketData Convergence Protocol, PDCP) service data unit (Service D...
