综上所述,现有技术的缺点在于:R6中RLC层位于无线网络控制(RNC), RLC的UM实体和AM实体发送端支持基于等大小PDU的分割级联,接收端支持SDU 的有序递交及无序递交,且RLC的UM和AM实体是^^艮据业务来建立。 In summary, the disadvantages of the prior art in that: R6 RLC layer is located in the radio network controller (the RNC), a UM entity and RLC AM entity transmit end supports segmentation concatenation based on size and the like of the PDU, the receive end supports SDU ordered submit and disorderly submitted, and the UM and AM RLC entity is ^^ Burgundy data traffic to build. 在EUTRAN 系统中,RNC被取消,RLC层下移到基站,可以单独作为一层,也可与MAC层合并为MAC +层,这样为了更好的利用空口的传输效率及减少填充,分割级联可以基于灵活的PDU尺寸;且EUTRAN系统接入网架构是全IP架构,PDCP层位于接入网关(aGW),这样只有按PDCP层发数据包的顺序接收数据,才能减少解头压缩时的出错,而RLC层的SDU有序递交已不能保证PDCP层的按序接收。 In an EUTRAN system, the RNC is canceled, the RLC layer to the next base station, may be used alone as one layer, may also be combined with the MAC layer as MAC + layer, so that transmission efficiency in order to better utilize the air interface and reduce fill, segmentation concatenation can be based on a flexible PDU size; and the access network EUTRAN system is an all-IP architecture, PDCP layer is located in an access gateway (the aGW), so that only the data received by the retransmission data packet PDCP layer sequence, in order to reduce errors at the time of header compression Solutions while the SDU RLC layer can not guarantee ordered to submit sequentially receiving PDCP layer. 综上所述R6协议的RLC层AM和UM实体特性已不能满足EUTRAN系统需求。 AM and UM RLC layer entity characteristics R6 summary protocol can not meet the needs of the EUTRAN system.
