Problems solved by technology

[0007] To sum up, since both the PDCP layer and the RLC layer cache data, this increases the processing burden of the CPU and causes waste of memory, thereby limiting the processing capacity of the system

Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0030] The invention is applicable to a wireless communication system adopting an air interface protocol, and the system may be a wideband code division multiple access (WCDMA) communication system.

[0031] see figure 1 , which is a flowchart of the data processing method of the present invention. The method includes the following steps:

[0032] Step 1: The PDCP layer processes the compressed context data or the PDCP SDU from the upper layer to generate a PDCP PDU, and sends the PDCP PDU to the RLC layer.

[0033] The PDCP layer processes the compression context data as follows: adding a PDCP protocol header. The PDCP layer processes the PDCP SDU as follows: when the header compression is valid, the PDCP SDU header is compressed and the PDCP protocol header is added; when the header compression is invalid, the PDCP protocol header is not processed or added.

Abstract

This invention provides a data process method and communication devices of packet accumulation protocol layer and a radio link control layer, in which, the method includes: 1, a PDCP layer generates PDCP PDU after processing the compressed context data or the PDCP SDU from the upper layer and transmits the PDCP PDU to the RLC layer, 2, the RLC layer buffer-stores the PDCP PDU layer and processes it to generate RLC PDU and transmit it to the opposite RLC layer. When the head compression is effective, step 1 further includes, the PDCP layer transmits the un-compressed message head to the RLC layer and step 2 includes the RLC layer buffer-stores it.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a data processing method and a communication device of a packet data convergence protocol layer and a wireless link control layer in the wireless communication system. Background technique [0002] Currently, the Universal Mobile Telecommunications System (UMTS) is introduced into the wireless communication system, which mainly consists of three parts: Core Network (CN), Universal Terrestrial Radio Access Network (UTRAN) and Terminal (UE). The connection between the UE and the UTRAN is over the air interface (Uu). [0003] The air interface is divided into three layers: physical layer, data link layer and network layer. The Packet Data Convergence Protocol (PDCP) layer and the Radio Link Control (RLC) layer are located at the data link layer. The PDCP layer mainly completes the functions of data transmission, header compression, sequence number synchronization and loss...
